Is your 1099-DA wrong?

From tax year 2026, exchanges report cost basis only for some of your coins. Answer five yes/no questions to see how likely your form is to show sales with a blank cost basis, and why.

01 Did you sell or convert crypto in 2025 or 2026?

Selling for dollars, or trading one coin for another, both count.

02 Did you move coins between exchanges or wallets?

For example, buying on Kraken and sending the coins to Coinbase.

03 Did you buy any of those coins before 2026?

Any purchase dated 2025 or earlier.

04 Did you earn staking or other rewards?

Staking, earn programs, airdrops, interest paid in crypto.

05 Did you use more than one exchange?

Any two or more: Coinbase, Kraken, Gemini, Robinhood, Cash App, and so on.

Answer all five to see your result.

The rules behind the check

Why would my 1099-DA show a blank cost basis?

Brokers report basis only for covered digital assets: ones acquired after 2025 in an account where the broker provided custody. Coins you transferred in, or bought before 2026, are noncovered and can show a blank basis. (IRS, Instructions for Form 1099-DA)

Did my 2025 Form 1099-DA include cost basis?

Usually not. The 2025 instructions say brokers are not required to report basis information for sales effected in 2025, so the basis has to come from your own records. (IRS, 2025 Instructions for Form 1099-DA)

Do I report a blank cost basis as $0?

No. For a sale reported without basis, enter the correct basis of the property in Form 8949 column (e), and keep the records that support it. (IRS, Instructions for Form 8949)
