The April 15 tax deadline is 16 days away, and if you traded, staked, or received any cryptocurrency during 2025, this filing season is fundamentally different from every year before it.

For the first time, the IRS is receiving Form 1099-DA from crypto exchanges — meaning the government now has direct visibility into your digital asset sales. At the same time, new per-wallet cost basis rules, the FIFO default trap, and ongoing confusion around staking and airdrop income are creating a minefield of potential errors.

This guide gives you everything you need: a complete step-by-step checklist, an explanation of every form involved, the five most expensive mistakes we see taxpayers make, and the tax-loss harvesting opportunity created by Bitcoin's 47% drawdown from its all-time high. Whether you file by April 15 or extend to October 15, this is the article to read before you do either.

1 · Why 2026 Is the Most Important Crypto Tax Year Ever

The 2026 filing season (covering tax year 2025) represents a watershed moment for cryptocurrency taxation in the United States. Three major changes have converged simultaneously, and together they give the IRS more information about your crypto activity than ever before.

The 1099-DA Debut

Starting with tax year 2025, digital asset brokers — including centralized exchanges like Coinbase, Kraken, and Gemini — are required to issue Form 1099-DA to both taxpayers and the IRS. Brokers were required to send these forms by February 17, 2026. The form reports gross proceeds from digital asset sales, giving the IRS a direct data point to match against your filed return.

However, there is a critical catch: for 2025 transactions, most 1099-DA forms do not include cost basis. The IRS explicitly warned in Tax Tip 2026-07 that "most of these statements will not include the basis for DA transactions in 2025 and taxpayers will have to calculate basis to determine their gain or loss." Cost basis reporting by brokers does not begin until 2027 for 2026 transactions.

IRS Data Matching Is Live

The IRS now runs automated matching between broker-reported 1099-DA proceeds and amounts reported on your Form 8949 and Schedule D. If you reported $25,000 in proceeds but your exchange reported $40,000, the IRS's Automated Underreporter (AUR) system will flag the discrepancy and generate a CP2000 notice — often with proposed taxes, penalties, and interest included. This is the same system that has caught stock and bond misreporting for decades, now extended to crypto.

The Per-Wallet Cost Basis Shift

Under Rev. Proc. 2024-28, the IRS established that starting January 1, 2025, cost basis must be tracked on a per-wallet, per-account basis. The one-time safe harbor that allowed taxpayers to allocate unused basis across wallets expired December 31, 2024. If you did not act before that deadline, your cost basis may now be fragmented across accounts — and FIFO applies by default within each account.

2 · Your Step-by-Step Filing Checklist

Whether you file yourself or work with a tax professional, follow this sequence. Each step builds on the previous one.

#	Step	Details
1	Answer the Digital Asset Question	Form 1040 asks: "At any time during the tax year, did you receive, sell, exchange, or otherwise dispose of a digital asset?" Answer Yes if you had any crypto activity. This includes staking rewards, airdrops, and crypto-to-crypto trades — not just fiat cash-outs.
2	Gather Your 1099-DA Forms	Collect 1099-DA from every exchange you used. Check email, exchange dashboards, and IRS.gov. If any are missing or late, contact the exchange. Do not skip this step — the IRS already has their copy.
3	Export Transaction History	Download CSV transaction exports from every exchange and wallet. Include deposits, withdrawals, trades, staking rewards, and airdrops. This is your source-of-truth for cost basis.
4	Reconcile 1099-DA vs. Your Records	Compare exchange-reported proceeds to your own data. Flag mismatches, missing transfers, and duplicate entries. This prevents CP2000 notices.
5	Calculate Cost Basis	For each disposal, determine: acquisition date, cost basis (purchase price + fees), holding period. Remember: 1099-DA does NOT provide basis for 2025. You must calculate it yourself.
6	Fill Out Form 8949	Report each disposal: description, date acquired, date sold, proceeds, cost basis, gain or loss. Use Box A (1099-DA with basis), Box B (1099-DA without basis), or Box C (no 1099-DA).
7	Transfer Totals to Schedule D	Aggregate short-term and long-term totals from all Form 8949 pages onto Schedule D (Form 1040).
8	Report Ordinary Income	Staking rewards, mining income, airdrops, and referral bonuses go on Schedule 1 or Schedule C (if self-employed). Report at fair market value when received.
9	File or Extend	File by April 15 if ready. If not, file Form 4868 for an automatic extension to October 15. Pay estimated taxes owed by April 15 regardless.

💡 Pro Tip:

Use crypto tax software (Koinly, CoinLedger, CoinTracker, TokenTax) to automate steps 3–7. These tools import exchange data, calculate cost basis, and generate Form 8949 — often with direct TurboTax or TaxAct integration.

3 · Form 1099-DA Explained

Form 1099-DA (Digital Asset Proceeds from Broker Transactions) is the crypto equivalent of the 1099-B that stock brokers have issued for decades. Here is what you need to know about its first year.

What 1099-DA Shows (2025 Tax Year)

For the 2025 tax year, Form 1099-DA reports gross proceeds from disposals — the total amount you received when selling or exchanging digital assets through a custodial broker. It also includes the date and type of each transaction. This information goes to both you and the IRS.

What 1099-DA Does NOT Show (2025 Tax Year)

For 2025 transactions, most 1099-DA forms will not include your cost basis. This is because broker cost-basis reporting is not mandatory until 2027 (for 2026 transactions). The IRS explicitly confirmed this in Tax Tip 2026-07. This means if you rely solely on the 1099-DA, you may overstate your gains by the full amount of proceeds — because without basis, the IRS assumes your basis is zero.

What If Your 1099-DA Is Late or Missing?

The deadline for brokers to send 1099-DA was February 17, 2026. If yours has not arrived, contact the exchange directly. Some platforms experienced delays — Kugelman Law noted that Coinbase and Kraken had issues with initial 1099-DA delivery. If you cannot obtain it in time, file Form 4868 for an extension and reconcile during the extension period. But remember: you must still report all transactions whether or not you receive a form.

What If 1099-DA Numbers Don't Match Your Records?

Transfers between your own wallets can appear as "disposals" on some exchanges, inflating reported proceeds. Compare your 1099-DA line by line against your actual trading history. If there is a mismatch, report your correct numbers on Form 8949 and attach an explanation. Do not simply copy incorrect 1099-DA numbers.

4 · Form 8949 + Schedule D: Reporting Your Crypto

Every crypto disposal — sale, swap, or use as payment — must be reported on Form 8949 (Sales and Other Dispositions of Capital Assets). The totals then flow to Schedule D (Capital Gains and Losses), which is filed with your Form 1040.

Form 8949 Columns

Column	What to Enter
(a) Description	E.g., "1.5 BTC" or "0.8 ETH"
(b) Date Acquired	The date you originally purchased or received the asset
(c) Date Sold	The date you sold, swapped, or used the asset
(d) Proceeds	Fair market value at time of sale (should match 1099-DA if reported)
(e) Cost Basis	What you paid, including transaction fees and gas fees
(f) Code	Adjustment code if applicable (see below)
(g) Adjustment	Amount of adjustment
(h) Gain or Loss	(d) minus (e), adjusted by (g)

Which Box to Check?

Form 8949 has three checkbox categories. For the 2025 tax year, most crypto transactions will fall under Box B (1099-DA received but basis NOT reported to IRS) or Box C (no 1099-DA received at all). Box A (basis reported to IRS) will become more common starting with 2026 transactions when broker basis reporting becomes mandatory.

Short-Term vs. Long-Term

Form 8949 has two sections: Part I for short-term (held ≤ 1 year) and Part II for long-term (held > 1 year). The distinction matters significantly for taxes. For the 2025 tax year, short-term gains are taxed at ordinary income rates (10%–37%), while long-term gains enjoy preferential rates of 0%, 15%, or 20% depending on income. For a single filer, the 0% rate applies up to $48,350 in taxable income, the 15% rate covers $48,351–$533,400, and the 20% rate applies above $533,400.

Schedule D

After completing all Form 8949 pages, transfer your aggregate short-term and long-term totals to Schedule D. This form calculates your net capital gain or loss for the year. If you have a net loss, you can deduct up to $3,000 per year against ordinary income, with unlimited carry-forward to future years.

5 · The FIFO Trap and Cost Basis Rules

Cost basis is the single most consequential number on your tax return. It determines whether you owe $300 or $30,000. And in 2026, the rules have gotten more complex than ever.

FIFO: The Default That Can Crush You

FIFO (First-In, First-Out) is the IRS default method for crypto. It assumes you sell your oldest units first. If you bought BTC at $5,000 in 2020 and also at $90,000 in 2024, and you sell 1 BTC today at $66,500, FIFO assigns the $5,000 basis — giving you a $61,500 taxable gain. If you could choose specific identification and select the $90,000 lot, your result would be a $23,500 loss instead. That is an $85,000 difference in taxable income on a single coin.

Specific Identification: The Alternative

The IRS allows specific identification, which lets you choose exactly which lots to sell. But there are strict rules: you must provide written instructions to your broker at or before trade execution specifying the lot you want to dispose of. Retroactive lot selection is prohibited and will result in automatic FIFO treatment.

Notice 2026-20: Temporary Relief Extended

On March 18, 2026, the IRS released Notice 2026-20, extending the temporary relief for digital asset specific-identification through December 31, 2026. During this relief period, taxpayers may use alternative methods to adequately identify which units are being sold — even if their broker's system does not yet fully support the required documentation. This is a one-year extension of the prior relief under Notice 2025-7. However, this applies only to assets held in a broker's custody, not self-custodied wallets.

Per-Wallet Tracking: The New Reality

Since January 1, 2025 (per Rev. Proc. 2024-28), cost basis must be tracked on a per-wallet, per-account basis. You can no longer pool basis across multiple exchanges. If you hold BTC on Coinbase, Kraken, and a hardware wallet, each is a separate basis pool with its own FIFO queue unless you elect specific identification.

💡 Pro Tip:

If you are an active trader using multiple exchanges, specific identification with proper documentation can save thousands of dollars annually. Set up a standing instruction protocol with each exchange before executing trades.

6 · 5 Costly Mistakes to Avoid

These are the five most expensive errors we see taxpayers make during crypto tax season. Each one can trigger IRS notices, penalties, or inflated tax bills.

❌ Mistake #1: Not Reconciling Your 1099-DA

The IRS now data-matches 1099-DA proceeds against your Form 8949. If there is a mismatch — even due to a legitimate transfer being misclassified as a sale — you will receive a CP2000 notice with proposed taxes plus a 20% accuracy-related penalty. Always compare your 1099-DA line by line against your own records before filing.

❌ Mistake #2: Not Reporting Crypto-to-Crypto Trades

Many taxpayers believe only fiat cash-outs are taxable. This is wrong. Every crypto-to-crypto swap (BTC → ETH, SOL → USDC, etc.) is a taxable event. The IRS treats each swap as a sale of the first asset at fair market value. With data-matching now in effect, unreported swaps are easily flagged.

❌ Mistake #3: Falling Into the FIFO Trap

If you do not document specific identification before trade execution, the IRS defaults to FIFO — selling your oldest, cheapest lots first and maximizing your taxable gain. For long-term holders who accumulated at low prices, this can result in gains tens of thousands of dollars higher than necessary. As detailed in Section 5, proper lot selection can dramatically reduce your tax bill.

❌ Mistake #4: Forgetting Staking, Airdrop, and Mining Income

Staking rewards, airdrops, mining income, and referral bonuses are all taxable as ordinary income at fair market value when received (IRS Rev. Ruling 2023-14). This is separate from capital gains. Many taxpayers report their trading gains but forget to include $2,000 in staking rewards — which the IRS may now see through 1099-DA or 1099-MISC reporting.

❌ Mistake #5: Missing April 15 Without Filing an Extension

The failure-to-file penalty is 5% of unpaid taxes per month, up to 25% total. The failure-to-pay penalty adds another 0.5% per month plus interest. Filing Form 4868 takes 5 minutes and gives you until October 15. There is no reason to miss the deadline — even if your crypto records are incomplete, file the extension and pay your best estimate.

Penalty Summary

Penalty Type	Rate	Max
Failure to file	5% of unpaid tax / month	25% total
Failure to pay	0.5% of unpaid tax / month	25% total
Accuracy-related (negligence)	20% of underpayment	—
Fraud	75% of underpayment	—
Criminal tax evasion	Up to $100K fine + 5 years prison	—

7 · Tax-Loss Harvesting in a War Market

With Bitcoin trading at approximately $66,500 — down 47% from its all-time high of $126,000 — and the broader crypto market under pressure from the Iran war, oil shock, and Nasdaq correction, the current environment presents one of the most compelling tax-loss harvesting opportunities in recent memory.

How It Works

Tax-loss harvesting is the strategy of selling an asset at a loss to realize a capital loss for tax purposes. The loss can offset capital gains dollar-for-dollar, and up to $3,000 of excess losses can be deducted against ordinary income each year. Any remaining losses carry forward indefinitely to future tax years.

The Crypto Advantage: No Wash-Sale Rule

Unlike stocks and securities, cryptocurrency is not subject to the IRS wash-sale rule as of 2026. This means you can sell BTC at a loss and immediately repurchase it — locking in the tax loss while maintaining your exact same position. With stocks, you would need to wait 30 days, risking price movement. Crypto has no such restriction.

Example: BTC Purchased at $100,000

Item	Amount
Purchase price (2024)	$100,000
Current price (Mar 30 2026)	$66,500
Realized loss	−$33,500
Tax savings at 20% LTCG rate	$6,700
Tax savings at 37% ordinary income rate (if offsetting ST gains)	$12,395

After selling, you immediately repurchase BTC at $66,500 — your new (lower) cost basis. You maintain the same number of coins, but you've locked in the $33,500 loss for tax purposes.

💡 Pro Tip:

While the wash-sale rule does not currently apply to crypto, proposed legislation could change this in future years. Harvest losses now while the advantage exists. Monitor CLARITY Act developments for potential wash-sale changes.

8 · Need More Time? Filing an Extension (Form 4868)

If your crypto records are incomplete, your 1099-DA is missing or inaccurate, or you simply need more time to get it right, filing an extension is the smart move. A clean, accurate return filed in October is always better than a rushed, error-filled return filed in April.

How Form 4868 Works

File Form 4868 (Application for Automatic Extension of Time to File) by April 15, 2026. This grants an automatic six-month extension, moving your filing deadline to October 15, 2026. No reason required — the extension is automatic.

Critical Rule: Extension ≠ Extra Time to Pay

An extension gives you more time to file, not more time to pay. You must still estimate and pay any taxes owed by April 15 to avoid failure-to-pay penalties and interest. If your estimate is uncertain, it is safer to overpay slightly and receive a refund when you file the complete return.

How to File

Method	Details
IRS Free File	File Form 4868 electronically at no cost through IRS Free File partners
Tax software	TurboTax, H&R Block, and other platforms include extension filing
Pay online	Making a payment through IRS Direct Pay and indicating it is for an extension can serve as your extension request
Mail	Print and mail Form 4868 with payment (keep proof of mailing)

Don't Forget State Extensions

Many states accept the federal extension automatically, but some require a separate state extension form or payment. Check your state's Department of Revenue website before assuming you are covered.

Frequently Asked Questions

Do I need to report crypto if I didn't receive a 1099-DA?

Yes. The IRS requires you to report all crypto transactions whether or not you receive a Form 1099-DA. You are responsible for tracking every taxable event — sales, swaps, staking rewards, airdrops, and mining income. The 1099-DA is an information document, not a prerequisite for reporting. As the IRS stated in Tax Tip 2026-07: "Every taxpayer must report any related income, gains, or losses, whether they receive a Form 1099-DA or not."

Are crypto-to-crypto trades taxable?

Yes. Trading one cryptocurrency for another (e.g., BTC → ETH, SOL → USDC) is treated as a sale of the first asset. You must calculate capital gain or loss based on the fair market value at the time of the swap minus your cost basis in the asset you disposed of. This applies even if you never converted to U.S. dollars.

Can I change from FIFO to specific identification mid-year?

Yes. You can use different cost basis methods for different transactions and even for different cryptocurrencies. However, you cannot retroactively change a completed transaction's lot selection. If you used FIFO for January trades, those are locked in. Starting with your next trade, you can implement specific identification — but you must provide written instructions to your broker at or before trade execution.

Does the wash-sale rule apply to crypto in 2026?

No. As of the 2025 and 2026 tax years, the IRS wash-sale rule (which prevents claiming losses on securities sold and repurchased within 30 days) does not apply to cryptocurrency. You can sell crypto at a loss and immediately repurchase to lock in the tax loss while maintaining your position. However, proposed legislation may extend wash-sale rules to crypto in future years.

What happens if I miss April 15 without filing an extension?

The IRS imposes a failure-to-file penalty of 5% of unpaid taxes per month, up to 25% total. On top of that, the failure-to-pay penalty adds 0.5% per month plus interest. Filing Form 4868 by April 15 gives you an automatic 6-month extension to October 15, 2026. The extension takes minutes to file and completely eliminates the failure-to-file penalty — making it one of the most important 5-minute tasks of the entire tax year.

Your Form 1099-DA is arriving this week — and it's unlike any crypto tax form you've seen before. For the first time in history, the IRS is receiving transaction-level data from every major U.S. crypto exchange: Coinbase, Kraken, Gemini, Robinhood, PayPal, and more.

The deadline for brokers to deliver your 1099-DA is February 17, 2026. But here's the problem: for 2025 transactions, this form reports only gross proceeds — not cost basis. That means the IRS sees every dollar you received from selling crypto as pure profit — unless you correct it yourself.

This guide walks you through exactly what the 1099-DA is, what's missing, how much it could cost you, and the step-by-step process to file correctly before April 15.

⚠️ 1099-DA DEADLINE: FEBRUARY 17, 2026 — 3 DAYS LEFT

1. What Is Form 1099-DA?

Form 1099-DA is the crypto equivalent of the 1099-B that stock brokers have been sending for decades. It's an informational tax form issued by U.S. digital asset brokers — including centralized exchanges like Coinbase, Kraken, and Gemini — to report taxable digital asset disposals to both you and the IRS.

This form exists because of the 2021 Infrastructure Investment and Jobs Act, which required crypto brokers to adopt the same reporting framework as traditional securities. After years of delays and rulemaking, 2025 is the first tax year it's in effect.

Feature	1099-DA (Crypto)	1099-B (Stocks)
First Year	2025 tax year	Decades
Issued By	Crypto exchanges (CEX)	Stock brokers
Reports Proceeds	✅ Yes	✅ Yes
Reports Cost Basis	❌ Not for 2025	✅ Yes (covered securities)
Covers DeFi/DEX	❌ No	N/A
Covers Transfers	❌ No	✅ Broker-to-broker
Filed Per	Per transaction to IRS; consolidated to you	Consolidated

⚠️ Critical Distinction: The 1099-DA is an informational form — it does NOT determine your tax owed. It does NOT replace Form 8949. It is the starting point, not the final answer. Relying on it alone without reconciling cost basis is how people accidentally overpay thousands in tax.

2. What's Reported — and What's Dangerously Missing

✅ What IS on the 1099-DA

Field	2025 Transactions	2026+ Transactions
Date of sale/disposition	✅ Reported	✅ Reported
Gross proceeds	✅ Reported	✅ Reported
Asset type (BTC, ETH, etc.)	✅ Reported	✅ Reported
Number of units	✅ Reported	✅ Reported
Cost basis	❌ NOT reported to IRS	✅ Covered assets only
Gain/loss calculation	❌ NOT reported	❌ Partial
Date acquired	❌ Often missing	✅ Covered assets

❌ What is NOT on the 1099-DA

This is where most people get blindsided. The following taxable activities are completely absent from the 1099-DA:

Activity	On 1099-DA?	Still Taxable?
Crypto transferred IN from another exchange/wallet	❌ Shows $0 basis	✅ Yes — you must report
DeFi trades (Uniswap, Aave, Curve, etc.)	❌ Not included	✅ Yes
DEX trades (Jupiter, PancakeSwap, etc.)	❌ Not included	✅ Yes
Staking rewards	❌ (on 1099-MISC if >$600)	✅ Ordinary income
Mining income	❌ Not included	✅ Ordinary income
Airdrops	❌ Not included	✅ Ordinary income at FMV
Crypto received as payment	❌ Not included	✅ Ordinary income
NFT sales under $600	❌ Threshold exemption	✅ Yes
Stablecoin sales under $10,000	❌ Threshold exemption	✅ Yes (if gain exists)
Wrapping/unwrapping (ETH→WETH)	❌ Not included	⚠️ Possibly

⚠️ Just because it's not on the 1099-DA doesn't mean it's not taxable. You are still required to report ALL taxable disposals on Form 8949 — exactly as you have in prior years. The 1099-DA is additional reporting, not a replacement.

3. The $0 Cost Basis Trap (With Dollar Examples)

This is the single most expensive mistake you can make this tax season. Here's a real-world example:

You sold 1 BTC on Coinbase in 2025 for $66,000. Here's what happens depending on how cost basis is handled:

Scenario	Cost Basis	Taxable Result	Tax @ 24%
🔴 1099-DA only (no basis)	$0	+$66,000 gain	$15,840
🟡 FIFO default (bought $35K in 2021)	$35,000	+$31,000 gain	$7,440
🟢 Specific ID (bought $97K in 2024)	$97,000	−$31,000 loss	$0 (+ deduction)

$15,840 vs. $0 — Same sale. Same Coinbase account. The only difference: whether you report cost basis correctly.

Why Does This Happen?

For the 2025 tax year, brokers are only required to report gross proceeds to the IRS. Cost basis is NOT reported. Many taxpayer copies will show $0, "unknown", or simply leave the field blank.

If you import this into TurboTax, H&R Block, or hand it to your preparer without fixing the basis — the software calculates your gain as:

$66,000 proceeds − $0 basis = $66,000 taxable gain

That's $15,840 in tax on money you may have actually lost.

✅ Key Takeaway: Never file using only 1099-DA numbers. Always calculate your actual cost basis using purchase records or crypto tax software. Use Specific Identification to select the highest-cost lots first (HIFO strategy) to minimize gains or maximize deductible losses.

4. Notice 2025-7: The IRS Relief You Must Know

The IRS knows the 1099-DA system isn't perfect yet. That's why they issued Notice 2025-7 — providing temporary relief for the 2025 tax year.

What Notice 2025-7 Allows

Relief Provision	What It Means for You
Use your own lot identification	You can choose Specific ID (including HIFO) — not stuck with FIFO
Rely on your own records	Your purchase records / crypto tax software are valid cost basis sources
Override $0 basis on 1099-DA	You can report correct basis on Form 8949 even if the 1099-DA shows $0
Transition year flexibility	The IRS acknowledges brokers have incomplete data

✅ This relief is critical. Without it, taxpayers would be forced to accept $0 or "unknown" basis — which would result in billions in overtaxation across the crypto market. The IRS explicitly says: you are allowed and expected to report your own cost basis.

⚠️ This relief is temporary. Starting with 2026 transactions, brokers must report cost basis for "covered" digital assets. The window to use broad lot-identification flexibility may narrow. Act now while the rules favor taxpayers.

5. Form 8949: Where Every Crypto Trade Goes

The 1099-DA is what the exchange sends. Form 8949 is what YOU file. Every single crypto disposal — whether it appeared on a 1099-DA or not — must be reported here.

Which Box Do You Check?

Box	When to Use	Example
Box A	Short-term, basis reported to IRS on 1099-DA	N/A for 2025 (basis not reported yet)
Box B	Short-term, basis NOT reported to IRS	N/A for 2025
Box D	Long-term, basis reported to IRS on 1099-DA	N/A for 2025
Box E	Long-term, basis NOT reported to IRS	N/A for 2025
Box G	Short-term, reported on 1099-DA, basis reported to IRS	Future years (2026+)
Box H ⭐	Short-term, reported on 1099-DA, basis NOT reported to IRS	Most 2025 CEX trades
Box I ⭐	Short-term, NOT reported on any 1099	DeFi, DEX, wallet trades
Box K ⭐	Long-term, reported on 1099-DA, basis NOT reported to IRS	Most 2025 CEX trades (held >1 yr)
Box L ⭐	Long-term, NOT reported on any 1099	DeFi, DEX, wallet trades (held >1 yr)

✅ For 2025 filing, most crypto investors will use:
→ Box H or K for trades that appear on a 1099-DA (CEX trades)
→ Box I or L for everything else (DeFi, DEX, wallet-to-wallet, mining sales, airdrop sales)

Form 8949 Column Guide

Column	What to Enter
(a) Description	e.g., "1.0 BTC"
(b) Date acquired	Original purchase date
(c) Date sold	Sale/trade date
(d) Proceeds	Sale price (should match 1099-DA)
(e) Cost basis	YOUR calculated basis (not the $0 from 1099-DA)
(f) Adjustment code	Use code B if basis was not reported to IRS
(g) Adjustment amount	Difference between 1099-DA basis and your actual basis
(h) Gain or loss	(d) minus (e) plus/minus (g)

⚠️ If your proceeds don't match the 1099-DA: The IRS computer will flag the discrepancy. Always make sure Column (d) proceeds match what the exchange reported. Adjust cost basis in Column (e), not proceeds.

6. Exchange Comparison: Coinbase vs Kraken vs Gemini vs Robinhood

Not all 1099-DAs are created equal. Each exchange handles reporting differently. Here's what to expect:

Feature	Coinbase	Kraken	Gemini	Robinhood
Issues 1099-DA	✅ Yes	✅ Yes	✅ Yes	✅ Yes
Reports gross proceeds to IRS	✅	✅	✅	✅
Reports cost basis to IRS (2025)	❌ No	❌ No	❌ No	❌ No
Shows basis on taxpayer copy	⚠️ Partial	⚠️ Partial	⚠️ Partial	✅ More complete
Tracks transferred-in basis	❌	❌	❌	❌
Includes staking on 1099-DA	❌ (1099-MISC)	❌ (1099-MISC)	❌ (1099-MISC)	❌ (1099-MISC)
Includes DeFi/DEX	❌	❌	❌	❌
CSV export available	✅	✅	✅	✅
API for tax software	✅	✅	✅	⚠️ Limited
Delivery format	Consolidated PDF	Consolidated PDF	Consolidated PDF	Consolidated PDF
Expected delivery	By Feb 17	By Feb 17	By Feb 17	By Feb 17

✅ Key Insight: No single exchange gives you the full picture. If you used multiple platforms — or ever transferred crypto between them — you need crypto tax software to reconcile cost basis across all accounts. The 1099-DA from each exchange only covers what happened on that exchange.

PayPal & Cash App Users

PayPal and Cash App also issue 1099-DAs for 2025 crypto sales. PayPal's form may show $0 proceeds for certain conversions (e.g., crypto-to-crypto within PayPal). Don't assume $0 proceeds means $0 tax — verify every line against your transaction history.

7. Per-Wallet Cost Basis: The Rule That Complicates Everything

Starting January 1, 2025, the IRS banned the universal wallet method under Revenue Procedure 2024-28. This is the second major rule change hitting you this tax season — and it directly affects how you use your 1099-DA.

Before Jan 1, 2025	After Jan 1, 2025
Pool all BTC across wallets into one "universal" lot	Each wallet/exchange = separate tax account
Choose any lot from any wallet when selling	Can only select lots from the wallet where the sale happens
Flexible tax optimization across platforms	Must track basis per-wallet; FIFO default per wallet

How This Multiplies the 1099-DA Problem

Imagine you hold BTC on both Coinbase and Kraken:

Wallet	Purchase Price	Sale Price	FIFO Result
Coinbase (bought Jan 2024)	$97,000	$66,000	−$31,000 LOSS
Kraken (bought Mar 2021)	$23,000	$66,000	+$43,000 GAIN

Same asset (BTC). Same sale price ($66K). Completely different tax outcomes — a $31K deductible loss vs. a $43K taxable gain — depending on which wallet the sale occurs in.

And both 1099-DAs show $0 cost basis. So without correction, both sales look like $66,000 in pure profit to the IRS — that's $132,000 in phantom gains and over $31,680 in unnecessary tax.

8. 7-Step Filing Action Plan

Step 1: Collect ALL 1099-DAs (By Feb 17)

Check every exchange you used in 2025: Coinbase, Kraken, Gemini, Robinhood, PayPal, Cash App, Crypto.com. Download each 1099-DA from your account's tax documents section. You should receive one per exchange.

Step 2: Export Full Transaction History from Each Exchange

The 1099-DA doesn't include everything. Download your complete CSV transaction history from each platform. This captures transfers, staking rewards, referral bonuses, and small trades that may fall below reporting thresholds but are still taxable.

Step 3: Gather All Non-Exchange Records

Collect records for: DeFi/DEX trades (Uniswap, Aave, Jupiter, etc.), wallet-to-wallet transfers, mining income, airdrops, staking rewards from non-custodial validators, crypto payments received, and gifts.

Step 4: Import Everything into Crypto Tax Software

Software	Per-Wallet Tracking	Spec ID / HIFO	8949 Generation	Starting Price
CoinTracker	✅	✅	✅	$59/yr
Koinly	✅	✅	✅	$49/yr
CoinLedger	✅	✅	✅	$49/yr
TaxBit	✅	✅	✅	Free (basic)
Awaken Tax	✅	✅	✅	$50/yr
Summ	✅	✅	✅	$45/yr

Step 5: Reconcile 1099-DA Proceeds with Software Output

Compare gross proceeds on each 1099-DA against your tax software's totals. They should match. If they don't, common reasons include: fee handling differences, stablecoin conversion rounding, crypto-to-crypto trade price discrepancies. Document any differences.

Step 6: Choose Your Accounting Method

Method	How It Works	Best For
FIFO (default)	First purchased = first sold	Rarely optimal — often triggers highest gains
LIFO	Last purchased = first sold	Better if recent buys were at higher prices
HIFO	Highest cost lot sold first	✅ Usually best — minimizes taxable gains
Specific ID	You choose which lot to sell	✅ Maximum control — requires documentation

✅ Pro Tip: HIFO (Highest In, First Out) is usually the most tax-efficient method. Under Notice 2025-7, you are explicitly allowed to use Specific Identification for 2025 transactions. Most crypto tax software can automatically apply HIFO across your portfolio.

Step 7: File Form 8949 + Schedule D

Generate Form 8949 from your crypto tax software. Use Box H/K for trades reported on 1099-DA and Box I/L for trades not reported on any 1099. Transfer totals to Schedule D. If you have more than 50 transactions, attach the 8949 as a supporting PDF — TurboTax, H&R Block, FreeTaxUSA, and TaxAct all accept crypto tax software imports.

⚠️ Filing Deadline: April 15, 2026. If you need more time, file Form 4868 for an automatic extension to October 15. The extension gives you more time to file, but NOT more time to pay. Estimate and pay any tax owed by April 15 to avoid penalties.

9. FAQ: 15 Critical Questions About the 1099-DA

Q1: What is Form 1099-DA?

Form 1099-DA is a new IRS informational tax form that reports digital asset disposals (sales, trades, conversions) from U.S. crypto brokers. It's the crypto equivalent of the 1099-B for stocks. For 2025 transactions, it reports gross proceeds only — not cost basis. IRS Source →

Q2: When will I receive my 1099-DA?

The IRS deadline for brokers to deliver 1099-DA forms to taxpayers is February 17, 2026. Check your exchange account under Settings → Tax Documents. Some exchanges deliver electronically; others may mail a physical copy.

Q3: Does the 1099-DA include cost basis?

Not for 2025 transactions. Brokers are only required to report gross proceeds to the IRS this year. Cost basis reporting to the IRS begins for transactions on or after January 1, 2026, and only for "covered" digital assets. Your taxpayer copy may show partial or $0 basis.

Q4: What happens if I file using only the 1099-DA numbers?

The IRS will treat your sale proceeds as 100% gain because no cost basis offsets it. For example, selling 1 BTC at $66,000 would appear as $66,000 in taxable gains with a $15,840 tax bill at 24%. You must report your own cost basis on Form 8949 to avoid this.

Q5: Can I report my own cost basis if the 1099-DA shows $0?

Yes. Under Notice 2025-7, Section 4.02, the IRS explicitly allows taxpayers to use their own lot identification and cost basis records. You are allowed and expected to override $0 or "unknown" basis on the 1099-DA with your actual purchase records.

Q6: Do I need to match my 1099-DA exactly?

Your gross proceeds should match what the exchange reported — the IRS will cross-check this. However, your cost basis should reflect your actual records, not the exchange's incomplete data. Use Form 8949 Column (f) Code B and Column (g) to explain adjustments.

Q7: What about crypto I transferred into an exchange from a wallet?

The exchange cannot track cost basis for transferred-in crypto. The 1099-DA will show $0 basis for these assets. You must use records from the original purchase — whether that's another exchange, a DeFi protocol, mining records, or airdrop FMV — to determine and report the correct basis.

Q8: I used multiple exchanges. Do I get multiple 1099-DAs?

Yes. Each exchange issues its own 1099-DA covering only the transactions that occurred on that platform. If you traded on Coinbase, Kraken, and Gemini, expect three separate forms. Each one goes to both you and the IRS.

Q9: Are DeFi and DEX trades on the 1099-DA?

No. Decentralized exchanges and DeFi protocols are not currently required to issue 1099-DAs (though proposed regulations may change this). You must self-report all DeFi/DEX disposals on Form 8949 using Box I (short-term) or Box L (long-term).

Q10: What about staking rewards?

Staking rewards are taxable as ordinary income at fair market value when received. They are typically reported on 1099-MISC (if over $600), NOT on the 1099-DA. When you later sell staked crypto, the sale goes on Form 8949 with your cost basis being the FMV at the time the reward was received.

Q11: Does the wash sale rule apply to crypto?

As of February 2026, the wash sale rule does not apply to cryptocurrency. You can sell crypto at a loss and repurchase immediately — this is legal tax-loss harvesting. However, Congress has proposed extending the rule to crypto in future legislation. Tax-Loss Harvesting Guide →

Q12: What is per-wallet cost basis?

Starting January 1, 2025, under Revenue Procedure 2024-28, each wallet and exchange is treated as a separate tax account. You can no longer pool cost basis across platforms. FIFO is the default per wallet unless you elect Specific Identification. Per-Wallet Guide →

Q13: Can I use HIFO instead of FIFO?

Yes. Under Notice 2025-7's temporary relief, you can elect Specific Identification (which includes HIFO — Highest In, First Out) for 2025 transactions. This is usually the most tax-efficient method. You must maintain adequate records showing which specific lots you sold.

Q14: What if I don't receive a 1099-DA?

You are still required to report all crypto transactions regardless of whether you receive a 1099-DA. The IRS may still have received a copy from the exchange. Not receiving the form is not a valid excuse for non-reporting. If you traded on a U.S. exchange, contact them to request your form.

Q15: Should I file now or wait?

Wait until you have ALL 1099-DAs (deadline Feb 17) and have reconciled cost basis using tax software. Filing too early with incomplete data can result in overpaying tax. If you need more time, file Form 4868 by April 15 for an automatic extension to October 15. Pay estimated tax by April 15 to avoid penalties.

Coinbase Q4 $667M Loss: What It Means for Your Crypto Taxes and 1099-DA

On February 12, 2026, Coinbase (COIN) reported a $667 million net loss for Q4 2025 — ending an 8-quarter profit streak. Revenue dropped 22% year-over-year to $1.78 billion. Trading revenue crashed 37% YoY to $983 million. COIN stock closed at $141, down 68% from its all-time high of $444.

But here's what most investors are missing: this earnings report has direct tax implications for every Coinbase user filing in 2026. Your 1099-DA is arriving (deadline: Feb 17), cost basis rules just changed, and the numbers on that form may be dangerously incomplete.

⚠️ 1099-DA DEADLINE: FEBRUARY 17, 2026
Coinbase must deliver your Form 1099-DA by Feb 17, 2026. For 2025 transactions, this form reports only gross proceeds — NOT cost basis. If you file using only 1099-DA data, the IRS will treat your entire sale amount as 100% profit. IRS Source →

2. Why the $667M Loss Isn't What You Think

The headline is alarming — but the breakdown tells a completely different story:

Component	Amount	Type
Crypto asset portfolio loss	$718M	Largely UNREALIZED
Strategic investment loss (incl. CRCL)	$395M	Paper loss
Adjusted Net Income (operations)	+$178M	Profitable
Adjusted EBITDA	+$566M	Cash-generating

Translation: Coinbase's core business still made money. The $667M loss was driven almost entirely by unrealized drops in their own crypto holdings (mainly BTC and ETH) — not by operational failure. They hold $11.3B in cash, repurchased $1.7B of their own stock, and still generated positive Adjusted EBITDA.

💡 Why this matters for YOUR taxes: If Coinbase — a public company with hundreds of accountants — got hit by $718M in unrealized crypto losses, the same market decline is sitting in your Coinbase account right now. The question is whether you're reporting it correctly. Unrealized losses don't help you at tax time — but realized losses through tax-loss harvesting can save you thousands.

3. Your 1099-DA: What Coinbase Reports vs. What It Doesn't

This is the first year Coinbase is required to issue Form 1099-DA. Here's what's on it — and what's critically missing:

Field	2025 Transactions (This Filing)	2026+ Transactions (Next Year)
Date of sale	✅ Reported	✅ Reported
Gross proceeds	✅ Reported	✅ Reported
Cost basis	❌ NOT reported	✅ Covered assets only
Gain/loss calculation	❌ NOT reported	❌ Partial
Transferred-in assets basis	❌ Shows $0	❌ Still shows $0
DeFi / DEX transactions	❌ Not included	❌ Not included
Crypto-to-crypto trades	✅ Reported	✅ Reported

🚨 The Critical Danger: The IRS gets a copy of your 1099-DA showing your sales proceeds. Without cost basis, the IRS computer matches your sale at $0 cost = 100% taxable profit. You sold 1 BTC for $66,000? The IRS sees $66,000 in taxable gains — unless you report the correct cost basis yourself on Form 8949.

What Coinbase Cannot Track

Even when cost basis reporting becomes mandatory for 2026 transactions, Coinbase still cannot report basis for:

→ Crypto transferred IN from another exchange (MetaMask, Kraken, Ledger, etc.)
→ Crypto purchased before your Coinbase account was created
→ Crypto acquired through mining, airdrops, staking rewards, or hard forks
→ Crypto received as payment or gifts
→ Any DeFi/DEX activity (Uniswap, Aave, etc.)

For all of these, you are responsible for calculating and reporting cost basis on Form 8949. Coinbase's 1099-DA will show these as $0 basis — which means 100% taxable if you don't correct it.

4. The Missing Cost Basis Trap (With Dollar Examples)

Let's say you sold 1 BTC on Coinbase in 2025 for $66,000. Here's what happens depending on how cost basis is reported:

Scenario	Cost Basis	Taxable Result	Tax @ 24%
1099-DA only (no basis reported)	$0	+$66,000 gain	$15,840
FIFO default (bought at $35K in 2021)	$35,000	+$31,000 gain	$7,440
Average cost (if it were allowed)	$66,000	$0	$0
Specific ID (bought at $97K in 2024)	$97,000	‑$31,000 loss	$0 (+ deduction)

$15,840 vs. $0

Same 1 BTC sale. Same Coinbase account. The only difference: whether you report cost basis correctly.

✅ Key Takeaway: Never file your taxes using only the 1099-DA numbers. Always calculate your actual cost basis using purchase records or crypto tax software. Use Specific Identification to select the highest-cost lots first (HIFO strategy) — this minimizes gains or maximizes deductible losses.

5. Per-Wallet Rules: How Coinbase Handles the New IRS Mandate

Starting January 1, 2025, the IRS banned the universal wallet method under Revenue Procedure 2024-28. This means:

→ Each wallet and exchange is treated as a separate tax account
→ Cost basis cannot be pooled across platforms
→ FIFO is the default if you don't elect Specific Identification
→ Coinbase can only track basis for crypto bought and sold within Coinbase

What This Means for Coinbase Users Specifically

Situation	Coinbase Can Track Basis?	Your Action Required
Bought BTC on Coinbase → Sold on Coinbase	✅ Yes	Verify accuracy, choose Spec ID if beneficial
Bought BTC on Kraken → Transferred to Coinbase → Sold	❌ No — shows $0 basis	Manually calculate basis from Kraken records
Received BTC from mining → Sent to Coinbase → Sold	❌ No	Use FMV at time of mining as basis
Bought BTC on Coinbase → Transferred to Ledger → Sold on Kraken	❌ Not Coinbase's problem	Track basis from original Coinbase purchase
Staking rewards earned on Coinbase → Sold	✅ Partial	Verify FMV at time rewards were received
Airdrop received in Coinbase wallet → Sold	❌ Likely missing	Record FMV at time of airdrop

💡 Critical Insight: Coinbase holds more crypto than any other company — over 12% of all crypto globally. But their 1099-DA can only track cost basis for assets bought directly on Coinbase. If you've ever transferred crypto in from any other source, the basis is on you.

6. COIN Stock Down 68% — Tax-Loss Harvesting Opportunity

This section is for investors who hold COIN stock (not just crypto on Coinbase). With COIN trading at $141 — down 68% from its $444 all-time high — there's a significant tax-loss harvesting opportunity.

Purchase Price	Current Price	Loss per Share	100 Shares Loss
$444 (ATH)	$141	‑$303	‑$30,300
$350	$141	‑$209	‑$20,900
$250	$141	‑$109	‑$10,900
$200	$141	‑$59	‑$5,900

⚠️ IMPORTANT: Wash Sale Rule APPLIES to COIN Stock
Unlike crypto, COIN is a publicly traded stock. The wash sale rule applies. If you sell COIN at a loss, you cannot repurchase it within 30 days before or after the sale — or the loss is disallowed. This is the opposite of crypto, where the wash sale rule does not currently apply.

Strategy: COIN Losses Can Offset Crypto Gains

Here's where it gets powerful: Capital losses from COIN stock can offset capital gains from crypto sales. If you have $20,000 in crypto gains and $20,000 in COIN stock losses, they cancel out — $0 tax. Any excess loss up to $3,000 offsets ordinary income. Remaining losses carry forward to future years.

7. 5-Step Action Plan Before April 15

Step 1: Receive and Review Your 1099-DA (By Feb 17)

Check your Coinbase account → Tax Documents section. Download the 1099-DA when available. Review every transaction listed. Flag any that show $0 cost basis — these need manual correction.

Step 2: Export Your Full Transaction History

Go to Coinbase → Settings → Taxes → Download Reports. Export your complete transaction history CSV. This includes transfers, staking rewards, and trades that may not appear on the 1099-DA.

Step 3: Import into Crypto Tax Software

Use a dedicated crypto tax tool to calculate your actual cost basis per wallet:

Software	Per-Wallet Tracking	Spec ID / HIFO	Starting Price
CoinTracker	✅	✅	$59/yr (100 txns)
Koinly	✅	✅	$49/yr (100 txns)
CoinLedger	✅	✅	$49/yr
TaxBit	✅	✅	Free (basic)
Awaken Tax	✅	✅	$50/yr

Step 4: Reconcile 1099-DA with Your Records

Compare the 1099-DA gross proceeds against your tax software's output. If numbers don't match, use Form 8949 Column (e) to explain the difference. Common reasons for mismatch: transferred-in crypto ($0 basis on 1099-DA), missing staking rewards, fee calculations.

Step 5: File Form 8949 + Schedule D

Report all crypto disposals on Form 8949. Use Column (f) Code B for short-term and Code E for long-term if cost basis was NOT reported on the 1099-DA. Transfer totals to Schedule D. If you have COIN stock losses, report those on a separate 8949 from your broker's 1099-B.

✅ Pro Tip: If you have more than 50 crypto transactions, most tax software generates the Form 8949 automatically. You can attach it as a supporting PDF to your tax return. TurboTax, H&R Block, and FreeTaxUSA all accept crypto tax software imports.

8. FAQ: 15 Critical Questions About Coinbase Q4 and Your Taxes

Q1: Did Coinbase actually lose $667 million?

Yes, on a GAAP (Generally Accepted Accounting Principles) basis. However, $718M came from unrealized crypto portfolio losses and $395M from strategic investment declines. On an adjusted basis, the core business generated $178M in net income and $566M in EBITDA.

Q2: Is Coinbase in financial trouble?

No. Coinbase holds $11.3 billion in cash and cash equivalents, repurchased $1.7 billion of its own stock, and has $2.3 billion remaining in buyback authorization. The company guided Q1 2026 transaction revenue of approximately $420M through Feb 10.

Q3: When will I receive my Coinbase 1099-DA?

The IRS deadline for brokers to deliver 1099-DA to taxpayers is February 17, 2026. Check your Coinbase account under Settings → Tax Documents. It may also arrive by mail or email.

Q4: Does the Coinbase 1099-DA include cost basis?

Not for 2025 transactions. The 1099-DA only reports gross proceeds this year. Cost basis reporting becomes mandatory for "covered" digital assets starting with transactions on or after January 1, 2026. IRS Source →

Q5: What happens if I just file using the 1099-DA numbers?

The IRS will treat your sale proceeds as 100% gain because no cost basis is shown. For example, selling 1 BTC at $66,000 would appear as a $66,000 taxable gain with a $15,840 tax bill at 24%. You must report your own cost basis on Form 8949.

Q6: What about crypto I transferred into Coinbase from another wallet?

Coinbase cannot track cost basis for transferred-in crypto. The 1099-DA will show $0 basis for these assets. You must use records from the original purchase platform to determine and report the correct cost basis.

Q7: Can I use HIFO (Highest In, First Out) on Coinbase?

Coinbase's default reporting may use FIFO, but you can elect Specific Identification (which includes HIFO) on your tax return. The key is proper documentation showing which specific lots you sold. Crypto tax software like CoinTracker and Koinly automate this.

Q8: I hold COIN stock at a loss. Can I harvest the loss?

Yes, but the wash sale rule applies to stocks. If you sell COIN at a loss, you cannot repurchase COIN (or a "substantially identical" security) within 30 days before or after the sale. COIN losses can offset crypto gains and up to $3,000 of ordinary income.

Q9: Does the wash sale rule apply to my crypto on Coinbase?

As of this writing (February 2026), the wash sale rule does not apply to cryptocurrency. You can sell BTC at a loss and buy it back immediately. However, Congress has proposed extending the rule to crypto — this could change in a future tax year.

Q10: What is the per-wallet cost basis rule?

Starting January 1, 2025, under Revenue Procedure 2024-28, you can no longer pool cost basis across all your wallets. Each exchange or wallet is treated as a separate tax account with its own cost basis tracking. IRS Rev. Proc. 2024-28 →

Q11: My 1099-DA shows transactions I don't recognize. What do I do?

This could be from automated conversions, staking rewards, or referral bonuses. Log into Coinbase and review your full transaction history. If you believe transactions are incorrect, contact Coinbase support and document everything before filing.

Q12: Does Coinbase report to the IRS even if I don't get a 1099-DA?

Yes. Coinbase files the 1099-DA with the IRS regardless of whether you receive your copy. You are still obligated to report all crypto transactions. Not receiving the form is not a valid excuse for not reporting.

Q13: Are Coinbase staking rewards taxable?

Yes. Staking rewards are taxable as ordinary income at fair market value when received. The cost basis for future sale is the FMV at the time the reward was issued. Coinbase earned $152M in blockchain rewards revenue in Q4, down 18% QoQ.

Q14: What about international reporting — CARF 2027?

Starting 2027, the Crypto Asset Reporting Framework (CARF) will enable 48 countries to automatically exchange crypto transaction data. U.S. taxpayers using offshore exchanges will face much tighter scrutiny. Coinbase, as a U.S.-regulated exchange, already reports to the IRS. CARF 2027 Guide →

Q15: Should I switch from Coinbase to another exchange for tax purposes?

Switching exchanges doesn't solve the tax problem — it creates more complexity. Every transfer between exchanges is a potential tracking event. The real solution is proper documentation and per-wallet cost basis tracking using crypto tax software, regardless of which exchange you use.
