Sales tax documentation in Seller Central lives in several key locations. Navigate to Reports, then Tax Document Library to find your annual 1099-K forms and other tax-related documents Amazon generates. This section stores historical forms making it easy to retrieve information from previous years when needed.

For transaction-level detail, go to Reports and select Payments to access your Date Range Reports. These comprehensive files contain order-by-order information including taxes collected. You can filter by date range and download the data in various formats. The All Orders report under Orders also provides sales details with tax information.

Your Tax Settings area is another important location. Access it through Settings, then Tax Settings to view your nexus configurations, exemption certificates uploaded through ATEP, and Product Tax Code defaults. Regularly reviewing these sections ensures your documentation stays current and accessible for filing requirements or potential audits.
