What is Form 1099-DA?
Form 1099-DA is the US tax form on which a digital asset broker reports your sales of digital assets to the IRS and to you. Brokers report gross proceeds of sales from 2025, and cost basis for assets acquired from 2026 onward and kept in the same custodial account.
What it means for you
In the US, a 1099-DA can show proceeds with no cost basis — for coins acquired before 2026 or moved in from another wallet or platform — so the form alone may not show your gain or loss; your own records fill that gap. The IRS says transfers between your own wallets are not taxable even if an information return arrives.
How it works
The form reports gross proceeds, net of transaction costs, in box 1f and adjusted basis in box 1g. Basis reporting is mandatory only for covered securities: digital assets acquired after 2025 in an account where the broker provides custody and held there until sold. Coins acquired before 2026, or transferred in, are noncovered; a broker can report their basis voluntarily and check box 9. Optional reporting methods and de minimis thresholds let brokers report qualifying stablecoin sales, specified NFT sales and small payment-processor sales differently, or not at all.
An example
Say you bought a coin on a platform in 2024 and sell it there in 2026 for $5,000. Your 1099-DA can show $5,000 of proceeds, with box 9 checked and no basis, because the coin was acquired before 2026. Your gain still depends on what you paid in 2024.
