Quick answer

A reconciliation report proves your tax numbers are right — matching every transaction to a source record before filing.

Understanding Reconciliation Report on crypto

A reconciliation report is a verification document that matches all crypto transactions recorded in a tax calculation against original source data — exchange records, on-chain history, wallet exports, and bank statements. Reconciliation identifies missing transactions, duplicate entries, incorrect valuations, and unexplained discrepancies before a tax return is filed. It is the crypto equivalent of bank account reconciliation and is essential for high-transaction-volume investors and DeFi users. Professional tax accountants typically require a completed reconciliation before signing off on a crypto tax return.

What this means for your crypto activity

Catch errors before filing

Reconciliation catches errors before filing — preventing amended returns, penalties, and audit triggers.

Balance discrepancies

Unexplained wallet balances (discrepancies between expected and actual holdings) indicate missing transactions.

DeFi complexity

DeFi reconciliation is particularly complex due to protocol interactions, reward accruals, and LP positions.

Software-generated reports

Tax software generates reconciliation reports by matching imports against calculated positions.

Audit evidence

A clean reconciliation is evidence of a well-maintained transaction history in the event of an audit.

Seeing it in action

Example scenario

Michael uses KoinX to import all his exchange and wallet data. The reconciliation report shows his ETH balance in the software is 0.3 ETH higher than his actual on-chain balance — indicating a missing withdrawal transaction. He investigates, finds a transfer to a cold wallet not yet imported, adds it, and the reconciliation clears. He can now file with confidence that his calculations are accurate.
