The IRS crypto tax form every US trader needs to understand before filing.
1099-DA = "Digital Asset Proceeds From Broker Transactions". Your exchange sends it to you AND to the IRS. It is crypto's version of the stock 1099-B.
For 2025 (filed in 2026): the form shows what you SOLD for — not your cost basis, not your gain. Basis reporting starts with 2026 transactions.
Sold $8,000 of crypto you bought for $5,000? The form shows $8,000. Your taxable gain is only $3,000 — and you must report the basis yourself.
A blank or NA basis means the broker did not report it — not that your basis is zero. Reconstruct it from your records or you get taxed on the full proceeds.
Crypto-to-crypto swaps ARE reportable sales. Moving coins to your own wallet is not — but the gas fee can appear as a tiny disposal. Traded on 3 exchanges? You get 3 forms.
Each 1099-DA line becomes a row on Form 8949: proceeds, your basis, dates. The IRS matches both — skip a form and the CP2000 notice arrives.
The withdrawal-as-disposal trap, the double-reporting fix, the 1099-DA vs 1099-MISC split — all with worked numbers.
