Key Takeaways
- DeFi platforms are currently exempt from broker reporting requirements thanks to 2025 legislation.
- Centralized exchanges (CEXs) are now using Form 1099-DA to report your gross proceeds.
- You are still legally responsible for reporting all DeFi gains, losses, and income, even if you don't receive a tax form.
- Cost basis reporting from brokers is phased in; you'll likely need your own records for 2025/2026 transactions.
- The IRS uses blockchain analysis to cross-reference your filings with on-chain data.
The Big Shift: Why DeFi Protocols Aren't Reporting You
For a while, it looked like the era of "anonymous" DeFi trading was ending. In late 2025, the Treasury and the IRS tried to classify front-end services that facilitate trades as "brokers." This would have forced DeFi is a financial system built on blockchain technology that removes intermediaries by using smart contracts to provide services like lending, borrowing, and trading platforms to collect your info and send the IRS a Form 1099-DA. However, a massive shift happened on April 10, 2025, when legislation was signed that basically nullified those reporting obligations for DeFi brokers. This means that if you're using a truly decentralized exchange, that platform isn't going to be sending your data to the government. But don't confuse a "reporting exemption for the platform" with a "tax exemption for the user." You still owe taxes on your gains; the platform just isn't the one telling the IRS about them.Understanding Form 1099-DA and the CEX Gap
While DeFi platforms got a pass, your account at Coinbase or Gemini did not. These custodial brokers are now required to use Form 1099-DA, which is the official IRS information return used to report gross proceeds from the sale or exchange of digital assets. If you sold assets in 2025, you would have received this form in early 2026. Here is the catch: for the 2025 tax year, brokers only reported the gross proceeds-basically how much money you got from the sale. They aren't required to report your cost basis (what you originally paid) until the 2026 tax year. This creates a "data gap" where the IRS knows how much you sold your ETH for, but they don't know if you bought it for $100 or $3,000. You have to fill in those blanks yourself using your own wallet records.| Feature | Centralized Exchanges (CEX) | DeFi Platforms / Unhosted Wallets |
|---|---|---|
| Issues Form 1099-DA? | Yes | No |
| Reports Gross Proceeds? | Yes | No |
| Reports Cost Basis? | Phased in (starting 2026) | No |
| User Tax Obligation? | Must report all gains/losses | Must report all gains/losses |
The "Invisible" Taxable Events in DeFi
One of the biggest mistakes DeFi users make is thinking that if there's no 1099-DA, there's no tax. In reality, several common DeFi activities are fully taxable, even though they are temporarily exempt from broker reporting requirements under Notice 2024-57. Think about Liquidity Providing. When you deposit assets into a pool to earn fees, you aren't just "saving" money. Depending on how the pool works, swapping assets for an LP token can be a taxable event. The same goes for Staking; those rewards are generally treated as ordinary income the moment you earn them, valued at the fair market price on that day. Other "invisible" events include:- Wrapping and Unwrapping: Converting ETH to wETH might seem like a simple change in format, but you need to track if it triggers a disposal.
- Lending: Interest earned on platforms like Aave is taxable income.
- NFT Sales: While there are de minimis thresholds (around $600) that exempt brokers from reporting some NFT sales, you still have to report the gain if you sold an NFT for more than you paid.
How to Handle Cost Basis: FIFO and Alternatives
Since you can't rely on DeFi platforms to track your costs, you need a method to calculate your gains. The IRS default is FIFO, or First In, First Out, an accounting method where the first assets purchased are assumed to be the first ones sold. If you don't provide a specific "identification" of which token you sold, the IRS will assume you sold your oldest ones first. However, if you keep meticulous records-listing the exact date of acquisition, the cost, and the specific unit-you can use alternative methods. Notice 2025-7 provided some temporary relief for assets held in broker custody, but for your private wallets, the burden of proof is entirely on you. If you can't prove what you paid, the IRS may assume a cost basis of zero, meaning you pay tax on the entire sale amount.
The Risk of the "Audit Gap"
Why bother tracking every single swap if the DeFi protocol isn't reporting it? Because the IRS isn't just looking at 1099-DA forms. They use sophisticated blockchain analysis tools to map wallet addresses to real-world identities. If you report $50,000 in income on your tax return, but your CEX 1099-DA shows you withdrew $500,000 from a DeFi protocol into your Coinbase account, that's a massive red flag. The IRS can see the flow of funds. When your reported income doesn't match your on-chain activity, it often triggers an audit. In that scenario, the lack of a 1099-DA doesn't protect you-it just means you have to spend more time and money proving you didn't evade taxes.Do I still need to pay taxes if I didn't get a 1099-DA?
Yes. A 1099-DA is an information return for the IRS, not a trigger for your tax liability. Any time you sell, exchange, or spend a digital asset, it is a taxable event. You are legally required to report these on Form 8949 regardless of whether a broker notified the IRS.
What are the de minimis thresholds for NFTs and stablecoins?
There are thresholds of $600 for specified NFTs and $10,000 for qualified stablecoins. However, these only exempt the broker from the requirement to file a report. They do not exempt the taxpayer from paying tax on the gains.
What happens if I use an unhosted wallet?
Unhosted wallets (like MetaMask or Ledger) are currently exempt from third-party reporting requirements. This means no company is reporting your activity to the IRS, but you are still responsible for calculating your own gains and losses and reporting them on your annual tax return.
How do I handle cost basis for tokens I've moved between multiple wallets?
You must track the "transfer of basis." When you move a token from Wallet A to Wallet B, the cost basis moves with it. It is highly recommended to use crypto tax software that can sync via API or public address to track these movements automatically.
Is staking income taxed as a capital gain or ordinary income?
Generally, staking rewards are treated as ordinary income at the fair market value on the day they are received. When you later sell those rewards, any increase in value from the time you received them to the time of sale is treated as a capital gain.
Just a heads up for everyone using Kleros or other dispute protocols, make sure you're tracking those rewards too since they often fly under the radar unlike the big Aave harvests
totally agree with the CPA part 🙌 it saves so much stress in the long run
