1099-DA reconciliation for missing basis and mismatched crypto records.

Under current IRS reporting rules, basis reporting depends in part on whether the asset is a covered security and whether the broker has the necessary custody and acquisition history. Assets acquired before the covered-security effective date or transferred into a broker may be reported without basis. Your own records are still needed to calculate and support the appropriate amount.

The issuing broker is responsible for correcting an inaccurate form. We can help document discrepancies and organize the records used in a correction request, but we cannot change a form issued by another party or require the issuer to correct it.

Form 1099-DA is an information return from the broker. For capital-asset dispositions, Form 8949 is generally used to reconcile reported proceeds and basis with the amounts used on the tax return, and Schedule D summarizes applicable capital gains and losses. Our reconciliation package organizes the source records and exceptions for the taxpayer and tax professional; it does not determine the final filing position unless that work is expressly included in a separate engagement.

Not unless those services are expressly included in a separate engagement. Reconciliation prepares and documents the underlying records; the taxpayer and engaged tax professional remain responsible for final positions and filing decisions.

Start with every Form 1099-DA received, the issuer’s transaction export, relevant wallet addresses or view-only records, transfer history, available purchase records, prior tax-lot schedules, and the filing deadline.
