A customer charged back last year's sale. How do I reconcile it with this year's 1099-K?
Cross-Year Chargebacks and Form 1099-K. A specific owner scenario, the facts that change the answer, and the records needed for a tax review.
By AE Tax Advisors Team · Updated October 28, 2026
Match the chargeback to the original sale, then determine the proper year and type of adjustment from the actual facts and accounting method. A processor's current-year reporting does not automatically require rewriting the original sale-year return.
A specific business-owner situation
A customer disputes a November purchase in February. The retailer previously reported the sale, and February's settlement reduces the bank payout. The current reconciliation must retain both the old transaction reference and the new chargeback date.
Illustrative example, not a client result.
What to establish before filing
- Locate the original sale and its prior reporting.
- Separate the refunded sale amount from dispute fees.
- Reconcile current settlements and any corrected information return.
Which fact changes the answer?
A temporary dispute hold differs from a final reversal. Preserve the resolution date and any amount recovered after appeal instead of treating every notice as an irreversible customer refund.
A mistake to avoid
Subtracting the chargeback from sales and deducting it again as a separate expense counts the same reversal twice.
Records that support the decision
- Original order.
- Chargeback notice.
- Both years' processor reports.
- Filed sales workpaper.
The decision to document
Request a two-year transaction bridge that shows the original receipt, current reversal, fees and final result. Use the applicable return method to assign the tax adjustment.
