Overview

Amazon provides a built-in tax calculation service that helps third-party sellers meet their sales tax obligations on orders shipped within the United States. This service automates rate lookups, applies product-specific taxability rules, and generates reporting data — saving sellers from having to manage tax compliance entirely on their own. Understanding how this service works is essential for any seller shipping products to US destinations.

Key Points / What Sellers Need to Know

• Marketplace facilitator vs. seller-calculated tax — In states where Amazon acts as the marketplace facilitator, the platform itself handles calculating, collecting, remitting, and refunding sales tax. For orders destined to non-marketplace facilitator jurisdictions, sellers must configure their own tax settings.
• Professional plan required — Amazon's tax calculation service and associated tax reporting are only available to sellers subscribed to the Professional selling plan. Individual plan sellers do not have access to these tools.
• Product tax codes matter — Sellers can assign product tax codes to their inventory to ensure the correct taxability is applied. Categories such as clothing, books, food, and electronics each carry different tax treatment depending on the jurisdiction.
• Automatic rate updates — Sales and use tax rates are automatically maintained and updated by Amazon's tax rate provider, so sellers do not need to manually track rate changes across thousands of jurisdictions.
• Tax reporting is your responsibility — Even though Amazon calculates the tax, sellers are responsible for downloading their tax reporting documents regularly and maintaining their own records.

How the Service Works

Amazon's tax calculation engine uses several data points to determine the correct tax rate for each transaction. These include the buyer's destination address (city, state, and zip code), order origin information, and the order acceptance location. Tax is calculated individually for each item in an order, meaning different products can be taxed at different rates depending on their assigned product tax code and the applicable jurisdiction. The service breaks down tax by jurisdiction type, calculating separate rates at the state, county, city, and district levels. It also handles excise and gross receipt taxes that are commonly treated as sales and use taxes, such as those found in certain US states. However, the service does not calculate federal, state, or local regulatory fees like bottle deposits, e-waste fees, or recycling charges, nor does it handle cross-border tax on sales originating outside the US and shipping to US destinations.
