Overview

Every year, Amazon issues IRS Form 1099-K to eligible sellers, reporting their unadjusted gross sales. Understanding how to verify these figures against your own records is essential for accurate tax filing. This guide walks through how to generate the reports you need from Seller Central and explains why your numbers may not perfectly match what appears on the 1099-K.

Key Points / What Sellers Need to Know

• 1099-K reports unadjusted gross sales — The form reflects total transaction volume before fees, refunds, and other deductions. It is not your net income or profit.
• Date-based reporting discrepancies are normal — Amazon is required to report based on shipment date, while Seller Central transaction reports are based on order date. This timing difference can cause month-over-month variations.
• You must generate separate reports for FBA and seller-fulfilled orders — To get a complete picture of your gross sales, you need date range reports covering both fulfillment methods.
• Reports can take up to one hour to generate — If your report does not appear immediately in Seller Central, check back later.
• Tax identity information drives 1099-K generation — The form is generated based on the details you provided during the US tax identity interview in Seller Central.

How to Find Transactional Level Details

To verify the individual transactions that make up your 1099-K totals, you will need to generate date range reports from the Payments section of Seller Central. Navigate to the Reports dropdown menu and select the Date Range Reports option under the Payments section. You must create separate reports for both seller-fulfilled and FBA orders to capture all transactions. When configuring the report, select the Transaction report type and specify the date range matching the tax year in question. Once generated, locate your report in the list on the Date Range Reports page — look for the Transaction type in the column listing.

To calculate your unadjusted gross sales from these transaction-level reports, you will need to sum several line items including product sales, shipping credits, gift wrap credits, promotional rebates, and related tax amounts. This total should be calculated across both seller-fulfilled and FBA orders to arrive at a figure comparable to your 1099-K.
