1099-DA Reconciliation
2025 is Form 1099-DA's first year, and brokers often report gross proceeds with no cost basis. See what your exchange didn't report, and fill the gap from your own on-chain history.
Reconcile your 1099-DA
Your 1099-DA never leaves your browser as a file. We only send the disposal rows you upload (asset, dates, amounts) to match against your own on-chain history.
Reporting outside the US? Exchanges in the EU report under DAC8 and others under the OECD CARF. Build a CARF summary to reconcile against those reports.
