Overview

Amazon’s Tax Exemption Program (ATEP) lets qualified buyers—such as federal agencies, accredited resellers, and registered charities—receive sales‑tax‑free pricing when they purchase from sellers who have opted into the service. The program automatically validates exemption certificates, applies the tax‑free status at checkout, and stores the supporting documents for the seller. Sellers who join ATEP reduce manual paperwork and see fewer post‑order tax‑refund requests, which can improve cash flow and buyer satisfaction.

Key Points

• Automatic enrollment — When a seller saves its tax configuration in Seller Central, Amazon enrolls the account in ATEP unless the seller explicitly opts out.
• Mutual participation required — An exemption is only applied when both the buyer and the seller are enrolled in ATEP; otherwise the transaction proceeds with standard sales‑tax calculation.
• Order‑level exemption — If a qualified buyer places an order that ships to a jurisdiction covered by the buyer’s certificate, Amazon removes tax from every eligible line item in that order.
• Buyer‑driven visibility filter — Buyers can limit search results to sellers that accept tax exemptions, meaning non‑participating sellers may lose exposure to institutional purchasers.
• Certificate storage within 72 hours — Amazon collects the buyer’s exemption documents, validates the information internally, and makes the certificates downloadable from the seller’s account three days after the order is fulfilled.
• Marketplace Tax Collection (MTC) limitation — In states where Amazon handles tax calculation and remittance, sellers cannot download exemption certificates for those orders, even if the buyer is exempt.

How ATEP Works

1. Buyer registers exemption — The buyer completes an ATEP enrollment form, providing the organization’s name, entity type (e.g., government, reseller, charity), and the list of states or local jurisdictions where the exemption applies. For example, a nonprofit that is exempt in California and Oregon uploads its signed certificates for those two states.
