Crypto Exchange Tax Reporting: Understanding Form 1099-DA

For years, filing taxes on cryptocurrency felt like trying to assemble IKEA furniture without the manual. You had five different exchanges, three different forms (or none at all), and a spreadsheet that made your eyes water by midnight. That chaos is finally ending. Starting with the 2025 tax year, the Internal Revenue Service (IRS) requires digital asset brokers to report transactions using a new, standardized document: Form 1099-DA.

This isn't just another bureaucratic tweak. It’s a fundamental shift in how the government sees your crypto activity. If you’ve ever wondered why your tax bill didn’t match your exchange dashboard, or if you’re worried about an audit because you sold Bitcoin for Ethereum and forgot to log it, this change affects you directly. The goal? To make crypto taxation as straightforward as selling stocks. But don’t pop the champagne yet-there are traps here, especially regarding when cost basis data actually arrives.

What Exactly Is Form 1099-DA?

Form 1099-DA is a tax information return titled "Digital Asset Proceeds from Broker Transactions." It was created under the Infrastructure Investment and Jobs Act of 2021 to close the gap between traditional securities reporting and the wild west of crypto. Think of it as the crypto equivalent of the Form 1099-B you get from Fidelity or Vanguard. Before this, exchanges could choose whether to send you a form, which one, and what data to include. Some sent nothing. Others sent a 1099-B that didn’t account for complex swaps. Now, every major U.S. exchange-think Coinbase, Kraken, and Binance.US-is legally required to use this specific form.

The most critical detail to understand right now is the phased rollout. For the 2025 tax year (which you file in early 2026), brokers will report gross proceeds only. This means they tell the IRS how much money you received when you sold or swapped assets, but they might not tell them how much you paid for those assets initially. Why does this matter? Because capital gains are calculated as Sale Price minus Purchase Price. If the IRS knows the Sale Price but has to guess or rely on your records for the Purchase Price, discrepancies can trigger audits. Full cost basis reporting kicks in for the 2026 tax year.

Who Has to Report and Who Doesn’t?

Not every platform sending you emails is a "broker" in the eyes of the IRS. The definition hinges on control and custody. A digital asset broker is defined as any entity responsible for regularly providing services that effectuate transfers of digital assets on behalf of another person. In plain English: if the exchange holds your keys and executes your trades, they are likely a broker. They must file 1099-DA forms.

• Centralized Exchanges (CEXs): Platforms like Coinbase, Kraken, and Gemini hold your private keys. They are definitely brokers and must report.
• Payment Processors: Services that let you pay merchants in crypto often fall under broker rules if they facilitate the transfer.
• Hosted Wallets: If you keep funds in a wallet provided by an exchange (not self-custody), expect a 1099-DA.
• Decentralized Exchanges (DEXs): Most DEXs like Uniswap do not take custody of your assets. Since you retain control, they generally aren’t considered brokers and won’t send 1099-DAs. You still owe taxes, but you have to track these yourself.
• Offshore Exchanges: Platforms that do not serve U.S. customers are exempt. However, if a global exchange serves U.S. users, they must comply.

This distinction creates a blind spot. If you trade heavily on decentralized platforms or use hardware wallets for peer-to-peer swaps, you won’t receive a 1099-DA. The IRS expects you to report this income anyway. Relying solely on the forms you receive in the mail is a recipe for underreporting.

The Cost Basis Problem: Why 2025 Is Tricky

Here is where things get messy for many investors. As mentioned, 2025 reports focus on gross proceeds. Let’s say you bought Bitcoin in 2021 for $30,000 and sold it in 2025 for $60,000. Your exchange will report the $60,000 sale to the IRS. If you don’t provide proof of the $30,000 purchase price, the IRS might assume your cost basis was zero, meaning you’d owe tax on the full $60,000. Or, they might apply a default method like FIFO (First-In, First-Out), which might not align with your actual strategy.

To avoid paying more than you owe, you need to maintain your own records until cost basis reporting becomes mandatory in 2026. Don’t trust the exchange’s auto-calculated gains if their cost basis data looks suspicious. Many users report discrepancies because exchanges sometimes fail to link deposits to withdrawals correctly across different blockchains or time periods. Keep a separate ledger or use third-party software that connects via API to verify the numbers before you file.

Handling NFTs and Staking Rewards

Non-Fungible Tokens (NFTs) have unique reporting requirements within the 1099-DA framework. Brokers must distinguish between "specified NFT sales" (typically first-time sales by creators) and other sales. If you flip NFTs frequently, you’ll see multiple entries. Ensure you categorize these correctly on your tax return. Selling an NFT for profit is a capital gain event, just like selling stock.

Staking rewards are treated differently. When you receive staking rewards, it’s ordinary income at the fair market value on the day you receive them. Later, when you sell those tokens, the difference between that initial value and your sale price is a capital gain or loss. While some exchanges previously reported staking on Form 1099-MISC, the move toward 1099-DA aims to consolidate this. Check your specific exchange’s policy, as some may still issue separate statements for income versus trading proceeds.

Practical Steps for Tax Season 2026

Filing for the 2025 tax year involves a few extra steps compared to previous years. Here is a checklist to keep you safe:

1. Gather All Forms: Collect every 1099-DA, 1099-B, and 1099-MISC you receive. Remember, each exchange sends its own form. If you used three platforms, you’ll have three forms.
2. Reconcile Gross Proceeds: Compare the total gross proceeds on your 1099-DA forms against your personal transaction history. Look for big mismatches.
3. Verify Cost Basis: Since the IRS might not have accurate cost basis data for 2025, manually check your original purchase prices. Use blockchain explorers if necessary to find transaction hashes and timestamps.
4. Report DeFi and P2P Trades: Add up all transactions that didn’t appear on a 1099-DA. Include swaps on DEXs, lending interest, and mining rewards.
5. Choose Your Method: Decide whether to use FIFO, LIFO, or Specific Identification for cost basis. Specific Identification gives you the most control but requires precise record-keeping of which coins you sold.

If you’re doing this yourself, budget at least 8-12 hours if you have multiple exchanges. Tax software like TurboTax or specialized tools like Koinly or CoinTracker can help import data, but they aren’t magic. They still require human review to catch errors in cost basis linkage.

What If I Made Mistakes in Previous Years?

The IRS has been cracking down on crypto non-compliance. Commissioner Danny Werfel has stated that enforcement is increasing through data matching. If you failed to report gains in 2022, 2023, or 2024, consider amending your returns. The penalties for underpayment can accumulate quickly, including interest and accuracy-related penalties. Professional tax preparers specializing in crypto typically charge between $350 and $600 for a return, significantly more than standard filings, but the peace of mind might be worth it given the complexity.

Also, note that receiving a 1099-DA doesn’t mean you’ve paid your taxes. It’s just information. You still must file Form 1040 and Schedule D. Ignoring the form because "I didn’t sell everything" is a common error. Even small swaps count as taxable events.
