7 Crypto Tax Mistakes That Trigger IRS Letters Most crypto investors do not get an IRS letter because they cheated. They get one because their return did not match what the IRS already knew. That gap between what you reported and what an exchange reported is what generates automated notices, and it is about to get wider. Starting with the 2025 tax year, digital asset brokers must report your sale proceeds to the IRS on a new form, Form 1099-DA. For the first time, the IRS gets its own copy of a lot of your activity. If your return does not line up, the mismatch is easy to spot. Here are seven mistakes that put you in that position, and how to stay out of it. 1. Ignoring the New Form 1099-DA For the 2025 tax year, brokers are required to report gross proceeds from digital asset sales to the IRS on Form 1099-DA, and basis reporting phases in for assets acquired starting in 2026. That means the IRS now receives a proceeds figure directly from your exchange. The mistake is assuming nobody is watching. If a broker reports $80,000 in proceeds and your return does not account for it, you have created a mismatch that a computer flags. The fix is to reconcile every 1099-DA you receive against your own records before you file. 2. Treating Crypto-to-Crypto Trades as Non-Taxable Swapping one coin for another is a taxable event, even though no dollars hit your bank account. Many investors assume tax only applies when they cash out to fiat, which is wrong and common. Every trade of one digital asset for another realizes gain or loss on the asset you gave up. Skip these and you understate income. The fix is to record every disposal, not just withdrawals to a bank. 3. Mismatched or Missing Cost Basis Across Wallets When you move assets between wallets and exchanges, cost basis does not always follow. Investors who use several platforms often end up with proceeds on one and no basis anywhere, which can inflate the gain the IRS sees. New rules generally require tracking basis on an account-by-account or wallet-by-wallet basis rather than one universal pool, which makes clean records more important than ever. The fix is consolidated tracking that ties every disposal back to what you actually paid. 4. Forgetting Staking, Airdrops, and Rewards Staking rewards, airdrops, and similar receipts are generally taxable as ordinary income at their fair market value when you receive them, and they create a basis you use later when you sell. Investors routinely forget this income entirely. The problem compounds: you owe income tax now and you need the basis later. Miss it and you can...
