If you do not know your crypto cost basis, the IRS will be happy to assume it is zero. That means you pay tax on every dollar of proceeds. Here is how to fix missing cost basis 1099-da.
The Zero Basis Problem
Many taxpayers received 1099-DA forms showing sales proceeds with no cost basis. The IRS automated matching system sees income with no offsetting basis and generates a notice for the full amount. You then have to prove your actual basis to reduce the assessment. If you cannot prove it, you pay tax on the full proceeds.
Cost Basis for Different Acquisition Methods
Purchased crypto uses the purchase price plus fees as basis. Mined crypto uses fair market value at receipt. Staking rewards use fair market value at receipt. Airdropped tokens use fair market value at receipt. Hard fork tokens use fair market value at receipt (if taxable). Gifted crypto uses the donor basis. Inherited crypto uses the fair market value at date of death. Each method has different rules and documentation requirements.
Cross-Exchange Transfers
When you transfer crypto from Exchange A to Exchange B and then sell on Exchange B, the cost basis from your original purchase on Exchange A must follow the asset. Exchange B does not know your basis - they only know when the crypto arrived. This is the most common source of missing basis on 1099-DA forms.
Professional Help
Cost basis reconstruction requires both crypto expertise and tax knowledge. A crypto tax attorney can reconstruct your basis, prepare defensible documentation, and represent you if the IRS challenges your claimed basis.
