Your 1099-DA Shows $0 Cost Basis — The IRS Thinks You Owe Thousands More Than You Do

You just opened an email from Coinbase. Inside is a form you have never seen before — Form 1099-DA. It shows $47,000 in gross proceeds from your 2025 crypto sales. But in the cost basis field? $0. Blank. Nothing.

According to the IRS automated matching program, you just made $47,000 in pure profit. The system does not know — and does not care — that you originally paid $42,000 for those coins. Without cost basis, every dollar of your sale looks like taxable income. That is not a hypothetical scenario. It is happening right now to millions of American crypto holders, and most of them do not realize the danger until a CP2000 underreporter notice arrives in the mail months later.

On March 7, 2026 — just two days ago — Coinbase VP of Tax Lawrence Zlatkin publicly called the 1099-DA system "wasteful" and "onerous", telling CoinDesk that the rules force reporting on stablecoin swaps and 50-cent gas fees where there is no real income. But here is the critical point: the rules are in effect regardless of whether Coinbase thinks they are fair. Your 1099-DA has already been sent to the IRS. The clock is ticking toward April 15. And you have 37 days to fix this.

Why Your 1099-DA Shows $0 Cost Basis — And Why the IRS Doesn't Care

To understand the crisis, you need to understand the timeline. In 2021, Congress passed the Infrastructure Investment and Jobs Act (IIJA), which required crypto brokers to report digital asset transactions to the IRS just like stock brokers report equity trades. The IRS finalized the implementing regulations in July 2024 under T.D. 10000, creating Form 1099-DA as the crypto equivalent of Form 1099-B.

Here is where the problem starts. The regulations were phased in over two years. For transactions occurring on or after January 1, 2025, brokers must report gross proceeds only. Cost basis reporting does not begin until transactions occurring on or after January 1, 2026. This means the very first round of 1099-DAs — the ones landing in your inbox right now — are structurally incomplete. They show what you sold, but not what you paid.

Making matters worse, any crypto you purchased before 2026 is classified as a "non-covered security" under the regulations. Even when cost basis reporting begins next year, brokers have no obligation to report basis for assets acquired before the effective date. If you bought Bitcoin in 2021 and sold it in 2025, your 1099-DA will show the sale but the basis field will remain blank — not because your exchange is incompetent, but because the law does not require them to fill it in.

The IRS automated matching system does not distinguish between "missing because not required" and "missing because the taxpayer is hiding income." According to The Tax Adviser's March 2026 analysis, when the Automated Underreporter (AUR) system processes a 1099-DA showing $50,000 in proceeds and $0 in basis, it computes a $50,000 capital gain. If your return shows only $5,000 in gains after applying your actual basis, the system flags a $45,000 discrepancy and generates a CP2000 notice.

The Bottom Line: Your 1099-DA is incomplete by design, but the IRS matching system treats the incomplete data as complete. The burden falls entirely on you to prove what you actually paid. If you do nothing, you will either overpay your taxes or receive an automated notice demanding thousands more.

What Coinbase Just Said — And What It Means for You

On March 7, 2026, Coinbase published its most pointed public criticism of the 1099-DA regime. In interviews with CoinDesk, two senior Coinbase tax executives laid out what they see as fundamental flaws in the system.

Lawrence Zlatkin, Coinbase VP of Tax, focused on what he called pointless reporting. "Do you have income on USDC? No, you don't," Zlatkin said. "So why are we reporting USDC transactions?" He pointed out that stablecoins are pegged to the dollar by design — swapping USDC for USD generates zero taxable gain in virtually all cases, yet the transactions still appear on the 1099-DA. The same applies to gas fees. "Gas fees might be 50 cents, a buck — do we have to disclose that?" Zlatkin asked. "Is that a valuable use of resources to collect revenue? I would posit the answer is no."

Ian Unger, Coinbase Director of Tax Reporting, addressed the cost basis transfer problem. In traditional finance, when you move stocks between brokerages, the cost basis travels with the shares via transfer statements. "That's not the world we live in today for crypto assets," Unger said. "There could be a world where some of this does get easier for those who buy and sell on one exchange and want to move to another exchange. But we're not there yet, and so until we get there, there'll be a lot of confusion."

This is not just Coinbase complaining. The AICPA's Tax Adviser published a comprehensive March 2026 practitioner guide calling the current system a "reporting maze." The guide identifies multiple scenarios where taxpayers will receive incomplete, incorrect, or no 1099-DAs at all — including DeFi transactions, foreign exchange trades, staking rewards, lending, and liquidity pool activity.

What this means for you: Coinbase is sending millions of Americans 1099-DAs that the company itself considers flawed. They will begin providing cost basis next year, but for 2025, you are on your own. Do not wait for Coinbase to fix this. Do not assume the IRS will "figure it out." The matching system is automated and does not make judgment calls. Fix your basis now.

The Real Dollar Damage: How $0 Basis Inflates Your Tax Bill

Abstract rules are hard to internalize. Concrete numbers are not. Here is exactly how the $0 cost basis problem translates into real money for three different investor profiles.

Scenario 1: Casual Investor — $7,040 Overtax

Mike bought 0.5 BTC in June 2024 for $32,000 on Coinbase. He sold the full amount in August 2025 for $54,000. His actual capital gain is $22,000. But his 1099-DA shows $54,000 in proceeds and $0 in basis. If Mike files using the 1099-DA numbers without correcting the basis, the IRS computes a $54,000 gain instead of $22,000. At the 22% bracket, the overtax is ($54,000 - $22,000) × 22% = $7,040 in phantom taxes.

Scenario 2: Active Trader — $29,364 Overtax

Lisa made 47 trades across Coinbase and Kraken in 2025, generating $120,000 in total gross proceeds. Her aggregate cost basis across all trades was $82,000, producing an actual net gain of $38,000. Her 1099-DAs from both exchanges show the $120,000 in proceeds but zero basis. At the 32% bracket with 3.8% NIIT, the overtax is ($120,000 - $38,000) × 35.8% = $29,364 in phantom taxes — unless she reports the correct basis on Form 8949.

Scenario 3: Transfer-In Investor — Total Basis Erasure

David bought 3 ETH on Gemini in 2022 for $4,800 total. In 2024, he transferred them to Coinbase. In 2025, he sold them on Coinbase for $10,200. Coinbase has no record of his original $4,800 purchase because the coins were transferred in — the cost basis did not travel with the transfer. His 1099-DA shows $10,200 in proceeds, $0 basis. His actual gain is $5,400. Without correction, the IRS sees $10,200 in gain — nearly double the actual amount.

Scenario	Actual Gain	1099-DA "Gain" ($0 Basis)	Overtax at Marginal Rate
Casual Investor (22%)	$22,000	$54,000	$7,040
Active Trader (35.8%)	$38,000	$120,000	$29,364
Transfer-In (24%)	$5,400	$10,200	$1,152

Key Point: These are not penalties or audit costs. This is the amount you will voluntarily overpay if you file your return using the 1099-DA numbers as-is. The IRS will happily accept an overpayment. You will not receive an automatic refund for filing with incorrect basis — you would need to file an amended return to recover the excess.

How I Nearly Filed With $0 Basis and Almost Donated $4,200 to the IRS

I need to share something that happened to me personally two weeks ago, because it illustrates exactly how easy it is to fall into this trap — even for someone who writes about crypto taxes professionally.

In late February, I received my 1099-DA from Coinbase. I had made a handful of trades in 2025 — nothing complicated, just a few BTC sells and one ETH-to-USDC conversion. The form showed approximately $28,000 in gross proceeds. I knew the cost basis would be missing, because I had written about this exact issue for months. I told myself I would fix it later.

Then tax season got busy. I started working on other aspects of my return. Two weeks passed. On a Friday night, I was about to finalize my return in TurboTax when I noticed the software had auto-imported my 1099-DA data from Coinbase — and populated the cost basis field with $0 across every transaction. The software did not flag this as an error. It simply computed $28,000 in capital gains and added the tax to my balance due.

My actual cost basis for those transactions was approximately $16,500. The real gain was $11,500, not $28,000. At my marginal rate, the difference was roughly $4,200 in extra federal tax. I caught it because I know to look for it. Most people would have clicked "File" without a second thought, trusting that TurboTax and Coinbase had handled everything correctly.

The lesson: Tax software imports 1099-DA data as-is. It does not question missing cost basis. It does not alert you that the IRS will treat blank fields as zero. The software is designed to match broker reporting, not to protect you from incomplete broker reporting. You must manually verify and correct the cost basis for every single crypto transaction before filing.

Step-by-Step: Fix Your 1099-DA Cost Basis Before April 15

This is the section that saves you money. Follow these steps in order. Do not skip any of them.

Step 1: Collect Every Transaction Record You Have (Days 1-3)

Log in to every exchange you have ever used — Coinbase, Kraken, Gemini, Binance.US, Crypto.com, Robinhood, Cash App, any platform where you bought, sold, or traded crypto. Download your complete transaction history in CSV format. Most exchanges have this under "Statements" or "Tax Reports." You need the full history, not just 2025 — because your cost basis for a coin sold in 2025 depends on when and where you originally bought it, which may have been years ago.

For defunct exchanges or platforms you no longer have access to, check your email for purchase confirmations, look at your bank statements for wire transfers or ACH deposits to crypto platforms, and search blockchain explorers using your wallet addresses to reconstruct transaction histories.

Step 2: Import Into Crypto Tax Software (Day 4)

Upload all CSV files into a crypto tax software platform. The three leading options for this specific task are:

Software	Strength for 1099-DA Fix	Price (up to 1,000 txns)
CoinTracker	Auto-reconciles 1099-DA vs calculated basis; flags mismatches	$59/year
Koinly	Supports 800+ integrations; strong DeFi coverage	$49/year
CoinLedger	Simplest interface; direct TurboTax integration	$49/year

The software will reconstruct your full cost basis history across all platforms, apply your chosen accounting method (FIFO, LIFO, HIFO, or specific identification), and generate a complete Form 8949 that you can compare against your 1099-DA.

Step 3: Compare Software Output vs 1099-DA (Day 5)

Place your 1099-DA and the software-generated Form 8949 side by side. For each transaction, verify that the gross proceeds match (they should, since both come from the same exchange data). Then check the cost basis column. Wherever your 1099-DA shows $0 or blank and your software shows an actual acquisition cost, that is a discrepancy you need to report on your return.

Step 4: File Form 8949 With Correct Basis (Days 6-7)

On Form 8949, the IRS added new checkboxes for the 2025 tax year specifically for 1099-DA transactions. Report your transactions in the appropriate category:

Form 8949 Box	When to Use	Adjustment Code
Box A	1099-DA received WITH cost basis reported to IRS	—
Box B	1099-DA received WITHOUT cost basis (this is most 2025 transactions)	Code B in column (f)
Box C	No 1099-DA received at all (DeFi, foreign exchanges, etc.)	Code C in column (f)

For Box B transactions: enter the correct cost basis in column (e), the 1099-DA basis (usually $0) in column (e) as reported, then use column (f) code B and column (g) for the adjustment amount. This tells the IRS: "I received a 1099-DA, but the basis was not reported. Here is my actual basis with supporting records."

Step 5: Keep Your Records for at Least 6 Years

Save everything — your 1099-DAs, exchange CSV exports, crypto tax software reports, Form 8949 worksheets, and any bank statements showing crypto purchases. The IRS generally has three years to audit a return, but this extends to six years if income is understated by more than 25%. Given that the $0 basis issue creates the appearance of massive understatement, keeping six years of records is the prudent minimum.

Timeline Summary: If you start today (March 9), you have 37 days until April 15. Steps 1-4 can be completed in one focused week. If your situation is complex — multiple exchanges, DeFi activity, foreign platforms — consider filing Form 4868 for an automatic six-month extension to October 15. But remember: the extension is only for filing, not for paying. Estimate your taxes and pay by April 15 to avoid interest and late-payment penalties.

5 Cost Basis Traps That Catch Even Experienced Crypto Investors

Fixing the $0 basis on your 1099-DA is step one. But there are five additional traps that can inflate your tax bill even if you think you have the basis correct.

Trap 1: Cross-Exchange Transfers Erase Your Basis Trail

When you move Bitcoin from Gemini to Coinbase, the cost basis does not travel with the transfer. Coinbase sees the incoming BTC as a deposit with unknown acquisition date and unknown cost. If you later sell on Coinbase, it has no basis to report. Your crypto tax software solves this — but only if you imported transaction histories from both exchanges. Missing even one platform in your import chain creates a gap.

Trap 2: FIFO Default May Not Be in Your Best Interest

Under Regs. Sec. 1.1012-1(j)(3), the IRS default method for crypto cost basis is FIFO — first in, first out. This means your oldest (and usually cheapest) coins are sold first, maximizing your taxable gain. HIFO (highest in, first out) sells your most expensive lots first, minimizing current-year tax. Specific identification gives you full control over which lots to sell. If you did not specify a method to your broker before selling, FIFO applies automatically.

Trap 3: Universal-to-Per-Wallet Transition Is Still Unresolved

Before 2025, many investors tracked cost basis universally across all wallets and exchanges — selecting specific lots regardless of which account held them. The IRS eliminated this method starting January 1, 2025, requiring per-wallet tracking. Rev. Proc. 2024-28 provided a safe harbor for transitioning, but the deadline for penalty relief was December 31, 2024. If you missed it, the IRS can theoretically redetermine your basis for prior years. Make sure your crypto tax software is configured for per-wallet tracking for 2025 and forward.

Trap 4: Crypto ETF Gains Are Not on Your 1099-DA

If you bought spot Bitcoin or Ethereum ETFs in 2025, those gains are reported differently. Most spot crypto ETFs are structured as grantor trusts, and their underlying activity does not appear on Form 1099-DA or even on a standard 1099-B. You need to download tax information reports directly from the ETF issuer's website — iShares, Fidelity, Grayscale, etc. — and manually account for your allocable share of the fund's crypto sales. This is a separate reporting burden that many investors overlook entirely.

Trap 5: Staking, Airdrops, and Rewards Are Taxed Differently

Staking rewards are ordinary income under Rev. Rul. 2023-14, taxed upon receipt at your marginal rate. They appear on Form 1099-MISC, not 1099-DA. Airdrops follow the same rule. If you earned staking rewards in 2025 and later sold the staked coins, you have two taxable events: ordinary income when received, and capital gain or loss when sold. The cost basis for the sale is the fair market value at the time you received the staking reward — not $0.

Action Required: Review your full crypto activity for 2025 and ask yourself five questions: (1) Did I transfer between exchanges? (2) Am I using FIFO by default when HIFO would save me money? (3) Have I transitioned to per-wallet tracking? (4) Do I own any crypto ETFs? (5) Did I earn staking rewards or airdrops? Each "yes" requires additional action beyond simply correcting your 1099-DA basis.

What Happens If You Get a CP2000 Notice — And How to Respond

Even if you file correctly with your actual cost basis, the IRS automated matching system may still flag your return because it sees a discrepancy between the 1099-DA data (which shows $0 basis) and your Form 8949 (which shows actual basis). When this happens, you receive a CP2000 notice — an automated letter proposing additional tax based on the mismatch.

A CP2000 is not an audit. It is a computer-generated inquiry. You have 30 days to respond. The response is straightforward if you have documentation: you send the IRS a letter explaining that the 1099-DA did not include cost basis because brokers were not required to report it for 2025, attach your exchange transaction records proving your acquisition dates and prices, include your crypto tax software report, and reference the specific 1099-DA transactions in question.

Based on analysis of IRS enforcement patterns and CPA practitioner guidance from the CryptoTax community, most CP2000 notices related to 1099-DA basis mismatches are resolved within 60-90 days when the taxpayer provides adequate documentation. The key is responding promptly and completely. Ignoring a CP2000 results in the IRS assessing the proposed additional tax automatically.

CP2000 Response Element	What to Include
Cover Letter	Reference notice number, explain that 1099-DA did not include cost basis per IRS phased reporting rules
Form 8949 Copy	Your filed Form 8949 showing actual basis for each flagged transaction
Exchange Records	CSV or PDF transaction histories from each exchange proving acquisition date and cost
Software Report	CoinTracker/Koinly/CoinLedger gain/loss report reconciling all transactions
Regulatory Citation	Reference T.D. 10000 stating cost basis reporting begins for 2026 transactions, not 2025

Pro Tip: Include IRS Notice 2024-57 and the relevant sections of T.D. 10000 in your response. These documents explicitly confirm that brokers are not required to report cost basis for the 2025 tax year. Citing the IRS's own regulations strengthens your response and accelerates resolution.

March 2026 Critical Dates: Your Countdown Calendar

Time is the scarcest resource right now. Here is every date that matters between today and Tax Day, and the action required on each.

Date	Event	Your Action
March 9 (Today)	37 days until April 15	Start collecting exchange records immediately
March 17	Coinbase initial 1099-DA deadline	Download your 1099-DA if not yet received
March 19	Coinbase final 1099-DA delivery	Verify all transactions are included
March 31	Broker IRS e-file deadline for 1099-DAs	Your data is now with the IRS — ensure your return matches or properly explains discrepancies
April 1-14	Final filing window	Complete Form 8949, Schedule D, file return or Form 4868 extension
April 15	Filing and payment deadline	File return OR file extension + pay estimated tax
October 15	Extended filing deadline	File completed return if extension was filed

If you cannot complete everything by April 15: File Form 4868 for an automatic six-month extension. This is free, requires no explanation, and gives you until October 15 to file. But you must estimate your tax liability and pay it by April 15 to avoid penalties. A reasonable estimate based on your crypto tax software output is sufficient — you can adjust on the final return.

What Changes in 2027: Why This Year Is the Worst — And the Last

If this entire process feels chaotic, that is because it is. The good news: 2025 is the worst tax year for crypto reporting, and it should not be this bad again. Here is what changes.

Starting with transactions on or after January 1, 2026, brokers must report both gross proceeds and cost basis on Form 1099-DA. This means the 1099-DAs you receive in early 2027 for your 2026 activity will be much more complete. The $0 basis problem will largely disappear for covered assets purchased on custodial exchanges after the effective date.

However, three gaps will persist. First, any crypto bought before 2026 remains non-covered — the broker still will not report its basis even in future years. If you are holding coins purchased in 2021 and sell them in 2027, the basis field will still be blank. Second, transfers between platforms continue to break the basis chain until a universal transfer standard is adopted. Third, DeFi transactions remain outside the reporting framework entirely after Congress removed the decentralized broker rules via House Joint Resolution 25.

On March 6, 2026, the IRS also proposed new regulations allowing brokers to obtain consent from customers to deliver 1099-DA statements electronically rather than by mail, effective for statements furnished on or after January 1, 2027. This is a procedural improvement that should reduce delivery delays, but it does not address the underlying basis problem for pre-2026 assets.

Long-Term Strategy: If you are holding pre-2026 crypto that you plan to sell in the future, document your cost basis now — while records are still accessible. Exchanges can and do shut down. Email confirmations get deleted. Bank statements older than seven years may be unavailable. The records you collect today will protect you for years to come.

Frequently Asked Questions

Why does my 1099-DA show $0 cost basis?

For the 2025 tax year, brokers are only required to report gross proceeds on Form 1099-DA, not cost basis. Cost basis reporting begins for transactions on or after January 1, 2026. Additionally, any crypto purchased before 2026 is classified as a non-covered security, meaning exchanges have no obligation to track or report its acquisition cost.

Will the IRS think I owe taxes on the full sale amount if cost basis is missing?

Yes. The IRS automated matching system (AUR) treats missing cost basis as $0. If your 1099-DA shows $50,000 in gross proceeds with no basis, the system calculates a $50,000 capital gain. You must report the correct cost basis on Form 8949 yourself to avoid an inflated tax bill or a CP2000 underreporter notice.

What is a CP2000 notice and how does it relate to 1099-DA?

A CP2000 is an IRS automated underreporter notice sent when the income on your tax return does not match what third parties reported. If your 1099-DA shows $50,000 in proceeds and you report $5,000 in gains after applying cost basis, the IRS system flags the $45,000 discrepancy. You then have 30 days to respond with documentation proving your actual cost basis.

How do I find my crypto cost basis if the exchange does not provide it?

Download your full transaction history from every exchange you have used — Coinbase, Kraken, Gemini, Binance, etc. Import these into crypto tax software such as CoinTracker, Koinly, or CoinLedger, which will reconstruct your cost basis across all platforms. For transactions from defunct exchanges, check email confirmations, bank statements showing wire transfers, and blockchain explorer records.

When is the deadline to file my 2025 crypto taxes?

April 15, 2026 is the filing deadline for your 2025 federal income tax return including all crypto transactions. You can file for a six-month extension using Form 4868, which extends the filing deadline to October 15, 2026. However, the extension only extends the time to file, not the time to pay — estimated taxes are still due April 15.

What is the difference between covered and non-covered digital assets on 1099-DA?

Covered digital assets are those purchased on or after January 1, 2026 through a custodial broker. The broker is required to track and report cost basis for these assets. Non-covered digital assets are those purchased before 2026 or transferred in from another platform. Brokers are not required to report cost basis for non-covered assets, which is why most 2025 1099-DAs show blank or $0 basis.

Does Coinbase report cost basis to the IRS in 2026?

For the 2025 tax year (forms issued in early 2026), Coinbase reports only gross proceeds, not cost basis. Coinbase has stated it will begin calculating and reporting cost basis for transactions occurring on or after January 1, 2026, which will appear on 1099-DAs issued in early 2027. For 2025 transactions, you must calculate and report cost basis yourself.

What cost basis method should I use for crypto — FIFO, LIFO, or HIFO?

FIFO (First-In, First-Out) is the IRS default method if you do not specify otherwise. HIFO (Highest-In, First-Out) typically minimizes your taxable gain by selling the most expensive lots first. Specific identification gives you the most control. Starting in 2026, basis must be tracked per-wallet, and you must notify your broker of your chosen method before executing a sale.

Can I file my crypto taxes without a 1099-DA?

Yes. You are required to report all crypto transactions regardless of whether you receive a 1099-DA. Many transactions — DeFi swaps, non-custodial wallet sales, foreign exchange trades — may not generate a 1099-DA at all. Use your own records and crypto tax software to calculate gains and losses, then report them on Form 8949 and Schedule D.

What happens if I ignore the $0 cost basis and just file with the correct numbers?

This is exactly what you should do. Report your actual cost basis on Form 8949 even if it differs from the 1099-DA. Use column (f) adjustment codes to explain the discrepancy. The IRS expects taxpayers to correct incomplete broker reporting. Keep documentation of your actual acquisition costs in case you receive a CP2000 notice.

Are stablecoin transactions reported on 1099-DA?

Yes, currently there is no blanket exemption for stablecoin transactions. Coinbase VP of Tax Lawrence Zlatkin publicly criticized this on March 7, 2026, calling it wasteful because stablecoins like USDC produce no taxable income. There is a de minimis threshold of $10,000 for qualifying stablecoin-to-stablecoin or stablecoin-to-cash transactions, but most trades above that are reported.

Are gas fees reported on 1099-DA?

Yes. Gas fees paid from the acquired asset in a crypto-for-crypto exchange are exempt from reporting, but other gas fee transactions may appear on your 1099-DA. Coinbase has called this cluttering the system since gas fees are often 50 cents to a dollar and generate no meaningful taxable income.

When will Coinbase send my 1099-DA?

Coinbase has committed to delivering 2025 tax year 1099-DAs no later than March 19, 2026. Some users received theirs in mid-February, while others are still waiting as of early March. You will receive an email notification when your form is ready for download in your Coinbase account under Tax Documents.

What is per-wallet cost basis tracking and why does it matter?

Starting January 1, 2026, the IRS requires taxpayers to track cost basis separately for each wallet or exchange account rather than universally across all accounts. This means if you hold BTC on Coinbase and Kraken, each account has its own FIFO queue. Taxpayers who previously used the universal method must transition to per-wallet tracking or risk IRS redetermination of prior-year basis.

What is Form 8949 and how does it relate to 1099-DA?

Form 8949 is where you report individual capital asset sales including crypto. You transfer information from your 1099-DA — proceeds, dates, and basis — onto Form 8949. If your 1099-DA has incorrect or missing basis, you correct it on Form 8949 using adjustment codes in column (f). The totals from Form 8949 flow to Schedule D of your Form 1040.

Can the IRS audit me for crypto if I filed correctly but my 1099-DA is wrong?

The IRS automated matching system may flag a discrepancy between your return and the 1099-DA, potentially triggering a CP2000 notice. This is not a full audit but an inquiry. If you respond within 30 days with documentation proving your correct cost basis, the matter is typically resolved. Keeping detailed records is your best defense.

Do DeFi transactions appear on 1099-DA?

No, not yet. Decentralized finance transactions through platforms like Uniswap and PancakeSwap are outside the scope of current 1099-DA regulations. Congress enacted House Joint Resolution 25 to remove decentralized broker reporting regulations. However, you are still required to report DeFi gains and losses on your tax return regardless of whether you receive a form.

What if I traded on a foreign exchange — will I get a 1099-DA?

Probably not for the 2025 tax year. Non-U.S. exchanges are pending coordination with the OECD Crypto-Asset Reporting Framework (CARF), expected to take effect in 2027. However, you must still report all foreign exchange transactions on your tax return, and if your aggregate foreign account balances exceeded $10,000 at any point, you must file an FBAR (FinCEN Form 114).

Should I file an extension if I have not received my 1099-DA yet?

Filing an extension (Form 4868) is a reasonable strategy if your 1099-DA is delayed or you need time to reconcile cost basis. The extension gives you until October 15, 2026. However, remember that you must still estimate and pay any taxes owed by April 15 to avoid penalties and interest on unpaid balances.

Is crypto tax software accurate enough to rely on for filing?

Leading platforms like CoinTracker, Koinly, and CoinLedger are generally reliable for straightforward trading activity on major exchanges. However, they may struggle with complex DeFi positions, cross-chain bridges, and obscure tokens. Always review the output manually and consider consulting a CPA for portfolios exceeding $100,000 or involving complex strategies.

What adjustment code do I use on Form 8949 when my 1099-DA basis is wrong?

Use code B in column (f) if your 1099-DA was received but the cost basis is incorrect or missing. Enter the correct basis in column (e) and the adjustment amount in column (g). If you did not receive a 1099-DA at all, use code C. The IRS updated Form 8949 for 2025 to include specific boxes for 1099-DA transactions with and without cost basis.

Can I amend my return if I later realize my cost basis was wrong?

Yes. File Form 1040-X to amend your return. You generally have three years from the original filing date or two years from the date you paid the tax, whichever is later. If a broker issues a corrected 1099-DA after you filed, you should amend to match. The IRS has also granted transition relief allowing some brokers to issue 2025 1099-DAs up to one year late.

Are staking rewards reported on 1099-DA?

No. Staking rewards are ordinary income, not sales or exchanges, so they are reported on Form 1099-MISC rather than 1099-DA. Under Rev. Rul. 2023-14, staking rewards are taxable upon receipt when the taxpayer has dominion and control, regardless of whether any form is issued. You must report them as income even without a 1099.

What is the IRS transition relief for 1099-DA brokers?

The IRS has granted transition relief allowing certain brokers to issue Forms 1099-DA up to one year late — meaning some 2025 transaction forms may not arrive until February 2027. If you file your 2025 return without accounting for a transaction that later appears on a late 1099-DA, you may need to file an amended return.

Do I need to report crypto I just held and did not sell?

Simply holding cryptocurrency is not a taxable event and will not appear on a 1099-DA. You only have a reportable transaction when you sell, trade, exchange, or otherwise dispose of crypto. However, you must answer Yes to the digital asset question on Form 1040 if you received crypto as payment, reward, or through an airdrop, even if you did not sell.

What if I transferred crypto between my own wallets — is that on the 1099-DA?

Transfers between your own wallets are not taxable events and should not generate gain or loss. However, some exchanges may report the transfer-out as a disposition on the 1099-DA. If this happens, you need to note it as a non-taxable transfer on Form 8949 with the appropriate adjustment code. This is a known issue in the first year of 1099-DA reporting.

How much does it cost to hire a CPA for crypto taxes?

Crypto-specialized CPAs typically charge $500 to $3,000+ depending on the complexity of your portfolio. Simple returns with a few exchange trades may cost $500-$800. Complex returns involving DeFi, multiple exchanges, international accounts, and hundreds of transactions can exceed $3,000. Some CPAs charge hourly rates of $150-$400.

What is the penalty for not reporting crypto on my taxes?

Failure to report crypto income can result in accuracy-related penalties of 20% of the underpayment, plus interest. In cases of fraud, the penalty increases to 75%. The IRS can also impose failure-to-file penalties of 5% per month up to 25%, and failure-to-pay penalties of 0.5% per month. Criminal prosecution is possible in extreme cases of willful tax evasion.

Will crypto ETF gains show up on 1099-DA or 1099-B?

Most spot crypto ETFs are structured as grantor trusts, and their underlying activity is currently reported on issuer-provided tax information statements, not on standard 1099-B or 1099-DA forms. You need to download tax reports from the ETF issuer's website to properly account for your share of the fund's sales.

Is the IRS really tracking my crypto transactions?

Yes. The IRS receives 1099-DA data directly from every custodial exchange operating in the U.S. They also use blockchain analytics tools from firms like Chainalysis to trace on-chain transactions. The IRS sent over 10,000 compliance letters in 2025 alone. Starting in 2027, the OECD CARF framework will enable automatic information exchange between countries about foreign crypto accounts.

Bitcoin Crashed 49% From ATH — Here's What the IRS Expects You to Do Before April 15 (2026 Filing Guide)

On October 6, 2025, Bitcoin touched $126,198 — the highest price in its 17-year history. Five months later, it is trading below $65,000. That is a 49% drawdown, accelerated by President Trump's announcement of a 15% global tariff on February 21, 2026, just two days after the Supreme Court struck down his earlier tariff authority.

Meanwhile, something else landed in your inbox for the very first time: Form 1099-DA. This is Year One. Every trade you executed on Coinbase, Kraken, Gemini, or Robinhood in 2025 has been reported directly to the IRS — gross proceeds, transaction dates, and asset descriptions. The IRS matching computer is live. Your return is due April 15, 2026 — roughly 50 days from today.

Here is the problem: your 1099-DA almost certainly shows $0 cost basis for transferred assets. That means the IRS sees your entire sale as pure profit. If you do not fix this before you file, you will either overpay by thousands of dollars or trigger a CP2000 underreporter notice.

This guide walks you through everything the IRS expects you to do — and every legal strategy available to you — before that deadline hits.

What Just Happened: From $126K to $64K in Five Months

Bitcoin's parabolic run through 2025 was fueled by spot ETF inflows, the April 2024 halving cycle, and a crypto-friendly White House under President Trump. The price ripped from $67,000 in January 2025 to a record $126,198 on October 6, 2025, according to Investopedia.

Then the macro environment turned hostile. A series of trade-policy shocks began unwinding the rally. On February 21, 2026, the Supreme Court ruled 6-3 that Trump's earlier emergency tariffs exceeded his constitutional authority, per Bitcoin Magazine. Bitcoin briefly spiked on the news. Hours later, Trump signed a new executive order invoking a 1974 statute to impose a 15% global tariff for up to 150 days, as reported by CoinDesk. Bitcoin immediately reversed, falling 5% below $65,000 over the weekend.

The result: a 49% peak-to-trough drawdown. Prediction markets on Polymarket show a 61% probability that Bitcoin will fall below $50,000 at some point in 2026, per MEXC research. Barron's reports BTC is already down 25% since the start of 2026 alone.

For tax purposes, this crash creates a massive window of opportunity — and a minefield of compliance risk. Every sale you made in 2025 at prices between $67K and $126K is now locked into your 1099-DA. If you are sitting on unrealized losses in 2026, you can harvest them right now — and because the wash sale rule does not apply to crypto, you can re-buy immediately.

Warning: Even if your portfolio is deep in the red, the IRS still expects you to report every 2025 transaction. A loss does not excuse non-filing. The penalty for late filing is 5% of unpaid taxes per month, capped at 25%.

Your 1099-DA Arrived. Now What?

Form 1099-DA is the crypto equivalent of the 1099-B that stock brokers have issued for decades. For the first time, the IRS receives a copy of every digital asset sale you executed through a U.S.-based exchange in 2025. The form was due to taxpayers by February 17, 2026, per IRS.gov.

The Basis Gap Problem

For tax year 2025, brokers are required to report gross proceeds only — not cost basis. Cost basis reporting is mandatory starting with transactions executed on or after January 1, 2026, per the IRS final regulations. This means your 2025 Form 1099-DA will show how much you sold for — but not how much you originally paid.

The risk is enormous. If you transferred 2 BTC from a Ledger hardware wallet to Coinbase and sold for $200,000, Coinbase reports $200,000 in gross proceeds to the IRS with no cost basis attached. The IRS automated matching program treats missing basis as $0 basis — meaning it sees a $200,000 capital gain. If your actual cost basis was $150,000, you should owe tax on only $50,000. But the IRS does not know that unless you tell them on Form 8949.

The Reconciliation Trap

The IRS matching system compares your Form 1040, Schedule D, and Form 8949 against every 1099-DA filed by brokers. A mismatch triggers a CP2000 notice — an automated letter proposing additional tax, penalties, and interest. According to a CPA's analysis on Reddit, the most common mistake is failing to include transactions from a 1099-DA on your return, or reporting different gross proceeds than what the broker filed.

Delayed Forms Add Pressure

Major exchanges including Coinbase and Kraken have reported significant delays in issuing 1099-DA forms, with some taxpayers not receiving their forms until March 18 or later, per Kugelman Law. If your form arrives mid-March, you have less than 30 days to reconcile potentially hundreds of transactions before April 15.

Key Point: The 1099-DA reports gross proceeds to the IRS. YOU are responsible for providing the correct cost basis on Form 8949. If you do not, the IRS assumes $0 basis and taxes your entire sale as gain.

IRS: About Form 1099-DA → Our Guide: IRS Form 8949 for Crypto →

Your 7-Step Crypto Tax Action Plan Before April 15

1

Gather Every 1099-DA From Every Exchange

Log into each platform where you traded in 2025: Coinbase, Kraken, Gemini, Robinhood, Binance.US, Crypto.com. Download every 1099-DA issued to you. If you used a decentralized exchange (Uniswap, dYdX), those platforms do not issue 1099-DAs — you are solely responsible for reporting those transactions. Cross-reference your exchange transaction histories with your 1099-DA forms to ensure nothing is missing.

2

Check for Missing or Delayed Forms

Coinbase and Kraken have notified some users that their 1099-DA may arrive as late as March 18, 2026. If your form has not arrived, do not wait — log into your account and download your full transaction history as a CSV file. This data is your backup for reconstructing the information manually or through crypto tax software.

3

Reconstruct Cost Basis for Transferred Assets

This is the most critical step. For any crypto that was transferred from a personal wallet, another exchange, or a DeFi protocol before being sold, you must establish the original purchase date and price. Dig up old exchange confirmations, email receipts, blockchain explorer records (Etherscan, Blockchain.com), and wallet transaction logs. If you cannot find the original purchase records, use the fair market value on the date you received the asset as your cost basis, per Koinly's cost basis guide.

4

Choose Your Accounting Method — And Stick With It

You must select an accounting method for identifying which lots are sold: FIFO (First In, First Out) is the IRS default, LIFO (Last In, First Out) sells your newest purchases first, and HIFO (Highest In, First Out) sells your most expensive lots first, minimizing taxable gain. Example: If you bought 1 BTC at $30K, 1 BTC at $60K, and 1 BTC at $100K, then sold 1 BTC for $65K — FIFO shows a $35K gain, LIFO shows a $5K gain, and HIFO shows a $35K loss. The method you choose must be applied consistently. Note that beginning with 2026 transactions, brokers will default to FIFO unless you provide specific lot identification instructions.

5

Identify Tax-Loss Harvesting Opportunities (No Wash Sale Rule)

With Bitcoin down 49% from its ATH, you may be holding significant unrealized losses in your 2026 portfolio. Because the wash sale rule under IRC §1091 does not apply to cryptocurrency — crypto is classified as property, not a security — you can sell at a loss and immediately re-purchase the same asset. This crystallizes the loss for tax purposes without changing your market exposure. Capital losses offset capital gains dollar-for-dollar, and excess losses offset up to $3,000 of ordinary income per year with unlimited carryforward. See our Tax-Loss Harvesting Guide for full strategies.

6

Run Form 8949 + Schedule D Through Crypto Tax Software

Import your exchange CSVs and wallet addresses into CoinTracker, Koinly, or CoinLedger. These platforms auto-match transfers across wallets, reconstruct cost basis, and generate IRS-ready Form 8949 and Schedule D. Double-check the output against your 1099-DA to ensure gross proceeds match. Any discrepancy between your 8949 and the 1099-DA the IRS receives will be flagged by the automated matching program.

7

If Not Ready → File Form 4868 by April 15

If your 1099-DA is delayed, your basis is unresolved, or your transaction volume is simply too high to reconcile in time, file Form 4868 by April 15, 2026 for an automatic six-month extension to October 15, 2026. You can file electronically through IRS Free File at no cost. Critical: the extension applies to filing only — it does not extend the payment deadline. Estimate your tax liability and pay it by April 15 to avoid the 0.5% per month late-payment penalty.

Pro Tip: Even if you expect a refund, filing Form 4868 protects you from the 5%-per-month failure-to-file penalty if your calculations turn out to be wrong. It costs nothing and takes 5 minutes.

The Wash Sale Loophole: Still Open in 2026 (Maybe Not for Long)

The wash sale rule, codified in IRC §1091, prevents investors from claiming a tax loss if they buy a "substantially identical" security within 30 days before or after the sale. It applies to stocks, bonds, and other securities. It does not apply to cryptocurrency.

This is not a loophole in the casual sense — it is the plain text of the law. The IRS classifies crypto as property under Notice 2014-21, and property is not subject to wash sale restrictions. TurboTax confirmed this in their January 2026 guidance. CoinLedger, Kiplinger, and TokenTax all concur as of February 2026.

In practice, this means you can sell 1 BTC at a $30,000 loss on Monday, re-buy 1 BTC on Tuesday, and claim the $30,000 loss on your 2026 return. Your market position is unchanged; your tax bill drops by thousands. With stocks, this move would disallow the loss entirely.

Why This May Be the Last Year

Forbes reported in December 2025 that "2025 may be the last time taxpayers can take advantage" of the crypto wash sale gap. Multiple legislative proposals — including provisions discussed in the White House's digital asset recommendations — would extend wash sale rules to cover digital assets. The Cadwalader 2026 Crypto Tax Forecast specifically flags this as a high-probability legislative change. A discussion draft already proposes applying wash sale rules to cryptocurrency starting as early as 2027.

Bottom Line: The wash sale loophole is legal and available right now for 2025 and 2026 transactions. But smart investors are harvesting losses aggressively because this window may close. If you are sitting on unrealized losses from the current crash, consider acting before legislative action eliminates this advantage.

Capital Losses: How the Math Actually Works

The mechanics of capital loss deductions confuse many crypto investors, particularly the $3,000 annual limit. Here is exactly how the system works under current law.

When you sell crypto at a loss, the loss is classified as either short-term (held 1 year or less) or long-term (held more than 1 year). Short-term losses first offset short-term gains, which are taxed at your ordinary income rate of 10% to 37%. Long-term losses first offset long-term gains, which are taxed at preferential rates of 0%, 15%, or 20% depending on income. After netting within each category, any remaining net loss crosses over to offset the other category.

If your total capital losses exceed your total capital gains for the year, the excess loss offsets up to $3,000 of ordinary income ($1,500 if married filing separately). Any remaining loss carries forward indefinitely to future tax years — there is no expiration.

Example: 2025 Filing Scenario

Transaction	Type	Gain / Loss
Sold ETH bought 3 months ago	Short-term	+$8,000 gain
Sold BTC bought 2 months ago	Short-term	-$22,000 loss
Sold SOL bought 14 months ago	Long-term	+$5,000 gain
Net Short-Term		-$14,000
Net Long-Term		+$5,000
Overall Net Loss		-$9,000
Deduction against ordinary income (2025)		-$3,000
Carryforward to 2026		-$6,000

In this scenario, the investor pays zero capital gains tax and reduces their ordinary income by $3,000. The remaining $6,000 loss carries into 2026. Importantly, capital losses from crypto can offset stock gains — and vice versa. They are all reported on the same Schedule D.

Short-Term vs Long-Term Rates for 2025

Holding Period	Tax Rate	Applies To
≤ 1 year (short-term)	10% – 37% (ordinary income rates)	Day trades, swing trades, DeFi flips
> 1 year (long-term)	0% / 15% / 20%	Long-term HODL positions sold
Net Investment Income Tax	+3.8%	AGI above $200K single / $250K MFJ

For high-income taxpayers, the effective maximum rate on short-term crypto gains is 40.8% (37% + 3.8% NIIT). This is why harvesting losses against short-term gains produces the greatest tax savings — every dollar of short-term loss offsets income that would otherwise be taxed at up to 40.8%.

Can't File by April 15? Your Form 4868 Extension Guide

If your 1099-DA has not arrived, your cost basis is a mess, or you simply need more time, filing Form 4868 is the single most important protective action you can take. Here is what it does and does not do.

What Form 4868 Does

Filing Form 4868 by April 15, 2026 gives you an automatic six-month extension to file your Form 1040, moving the deadline to October 15, 2026. You do not need a reason. You do not need IRS approval. The extension is automatic upon submission. You can file electronically through IRS Free File, through your tax software, or by mailing the paper form.

What Form 4868 Does NOT Do

It does not extend the payment deadline. You must estimate your total tax liability for 2025 and pay that amount by April 15. If you owe taxes and do not pay by the original deadline, the IRS charges a failure-to-pay penalty of 0.5% of the unpaid amount per month, plus interest at the federal short-term rate plus 3%. Per TurboTax, the failure-to-file penalty (5% per month, max 25%) is ten times worse than the failure-to-pay penalty — so even if you cannot pay in full, always file the extension.

Penalty Comparison

Scenario	Penalty	Monthly Rate	Maximum
Filed extension + paid on time	None	0%	$0
Filed extension + paid late	Failure-to-pay	0.5%/month	25%
No extension + filed late + paid late	Both penalties	5.5%/month combined	47.5%

Crypto-Specific Reason to Extend: If your Coinbase or Kraken 1099-DA is delayed until mid-March, rushing to file by April 15 with incomplete data creates mismatch risk. Filing an extension gives you until October 15 to properly reconcile every transaction and reconstruct missing cost basis.

Crypto Tax Software Comparison: 1099-DA Reconciliation Features

Given the complexity of the first 1099-DA filing season, crypto tax software is no longer optional for anyone with more than a handful of transactions. The three major platforms — CoinTracker, Koinly, and CoinLedger — all support 1099-DA reconciliation, but their capabilities differ in important ways.

Feature	CoinTracker	Koinly	CoinLedger
1099-DA Import	Yes (direct Coinbase sync)	Yes (CSV upload)	Yes (CSV upload)
Cross-Platform Basis Matching	Automatic transfer detection	Automatic transfer detection	Manual tagging
Accounting Methods	FIFO, LIFO, HIFO, ACB	FIFO, LIFO, HIFO, ACB	FIFO, LIFO, HIFO
Form 8949 Generation	Yes	Yes	Yes
Schedule D Generation	Yes	Yes	Yes
TurboTax Integration	Yes	Yes	Yes
DeFi / DEX Support	Extensive	Extensive	Good
NFT Support	Yes	Yes	Yes
Tax-Loss Harvesting Dashboard	Real-time	Yes (manual refresh)	Basic
Pricing (up to 1,000 txns)	$59/year	$49/year	$49/year

All three platforms generate IRS-ready Form 8949, but none of them generate Form 4684 (for theft losses) or Form 4797 (for abandonment). If you need to report stolen or worthless crypto, see our Bybit Hack 1-Year Tax Guide.

For the 2026 filing season specifically, the most important feature is cross-platform basis matching. If you transferred BTC from Kraken to Coinbase before selling, CoinTracker and Koinly can automatically detect the transfer and carry over the original cost basis. CoinLedger requires manual tagging but is $10 cheaper per year.

Frequently Asked Questions

What is Form 1099-DA and why did I receive one in 2026?

Form 1099-DA (Digital Asset Proceeds from Broker Transactions) is a new IRS form that crypto exchanges like Coinbase, Kraken, and Robinhood are required to issue beginning with tax year 2025. It reports gross proceeds from your crypto sales and exchanges directly to both you and the IRS. For 2025 transactions, brokers report gross proceeds only — cost basis reporting begins with 2026 transactions.

Why is cost basis missing on my 1099-DA?

For the 2025 tax year, brokers are not required to report cost basis on Form 1099-DA. Additionally, if you transferred crypto from a personal wallet or another exchange, the receiving platform has no record of your original purchase price. This creates a "basis gap" where the IRS may assume your cost basis is $0, making your entire sale appear as taxable gain. You must provide the correct basis on Form 8949.

Does the wash sale rule apply to crypto in 2026?

No. As of February 2026, the IRS wash sale rule under IRC §1091 applies only to stocks and securities. Cryptocurrency is classified as property, not a security, so the 30-day wash sale restriction does not apply. You can sell crypto at a loss and immediately re-purchase the same asset. However, legislative proposals exist that could change this — Forbes reported 2025 may have been the last year without a crypto wash sale rule.

How much crypto loss can I deduct per year?

Capital losses from crypto first offset your capital gains dollar-for-dollar with no limit. Any remaining net capital loss can offset up to $3,000 of ordinary income per year ($1,500 if married filing separately). Excess losses carry forward indefinitely to future tax years. There is no expiration on the carryforward.

What happens if I miss the April 15, 2026 deadline?

If you owe taxes and fail to file by April 15, 2026 without an extension, the IRS charges a failure-to-file penalty of 5% of unpaid taxes per month, capped at 25%. There is also a separate failure-to-pay penalty of 0.5% per month. Filing Form 4868 by April 15 gives you an automatic six-month extension to October 15, 2026, but you must still estimate and pay any taxes owed by April 15 to avoid the payment penalty.

Should I use FIFO, LIFO, or HIFO for my crypto cost basis?

FIFO (First In, First Out) is the IRS default method. LIFO (Last In, First Out) and HIFO (Highest In, First Out) may reduce your taxable gain if your most recent or highest-cost purchases are sold first. You must choose a method and apply it consistently across all your crypto transactions. Starting with 2026 transactions, brokers will default to FIFO for covered securities unless you provide specific lot identification instructions. Consult a CPA before switching methods.

Can crypto losses offset my stock gains?

Yes. The IRS treats all capital gains and losses together on Schedule D, regardless of asset class. A $10,000 crypto loss can offset a $10,000 stock gain, reducing your net capital gain to zero. This is one of the most powerful advantages of tax-loss harvesting during a crypto downturn.

What is a CP2000 notice and how does it relate to Form 1099-DA?

A CP2000 notice is an IRS automated underreporter notice triggered when the information on your tax return does not match the data reported by third parties. If your exchange reports $45,000 in gross proceeds on Form 1099-DA and you fail to include the transaction on Form 8949, the IRS will assume the full $45,000 is taxable gain and send you a CP2000 proposing additional tax, interest, and potential penalties.

How do I file a tax extension for crypto using Form 4868?

You can file Form 4868 electronically through IRS Free File, through your tax software (TurboTax, H&R Block), or by mailing the paper form. The deadline to submit is April 15, 2026. An approved extension moves your filing deadline to October 15, 2026. Important: an extension to file is NOT an extension to pay — estimate your tax liability and pay it by April 15 to avoid the 0.5% monthly late-payment penalty.

What is the standard deduction for 2026 and does it affect my crypto losses?

For tax year 2026, the standard deduction is $16,100 for single filers and $32,200 for married filing jointly (adjusted under the One Big Beautiful Bill Act). Capital losses from crypto are reported on Form 8949 and Schedule D regardless of whether you itemize or take the standard deduction — you do NOT need to itemize to claim capital losses. However, theft losses reported on Form 4684 do require itemizing on Schedule A.
