The 1099-DA Dilemma

Individuals who purchased Bitcoin in 2025 and made several disposals face uncertainty as their exchanges often lack complete transaction records. One person raised concerns about whether their future 1099-DA forms would reflect incorrect cost basis or proceeds from sales due to these unreported transactions.

A participant articulated the struggle, stating, "Will my exchange put the wrong cost basis and proceeds on a future 1099-DA?" This highlights a larger issue within the crypto community regarding accurate tax reporting amidst incomplete documentation.

The Consensus on Solutions

Recent forum discussions provide practical insights:

  1. Self-reporting is key: A user pointed out that the actual tax return controls the record. "Your tax return is what actually controls the record," they stated, underscoring the importance of accuracy in reported values. Maintaining personal records from software reports and wallet history is crucial for compliance.

  2. Wait for 1099-DA forms: An expert from a crypto tax tracking platform advised, "Some 1099-DA from exchanges are delayed, so you should wait" This suggests caution in filing tax reports to avoid mismatches that could trigger notices from the IRS.

  3. Document transaction history: Commentators emphasized that since exchanges know only what occurs on their platforms, discrepancies might arise if users donโ€™t accurately report disposals. Keeping a detailed history of transactions helps counter this issue.
