Amazon FBA sales tax compliance

Amazon FBA sellers in the U.S. must navigate complex sales tax compliance, influenced by marketplace facilitator laws, physical presence nexus from FBA inventory, and economic nexus thresholds. Amazon acts as a marketplace facilitator in many states, calculating, collecting, and remitting state sales tax for third-party sellers. However, sellers often retain responsibilities like state registration, filing returns (even zero returns), and collecting tax on non-marketplace sales. Storing inventory in Amazon fulfillment centers creates physical presence nexus in those states, requiring sellers to monitor inventory locations and register for sales tax permits. Economic nexus, triggered by sales revenue or transaction volume, also necessitates tracking sales across all channels and registering in states where thresholds are met, even if Amazon collects marketplace tax. Sellers must verify state-specific registration and filing requirements, as these vary. Resale certificates and Amazon's Tax Exemption Program (ATEP) are relevant for exempt transactions. Amazon provides essential tax reports for recordkeeping and audits. A recommended compliance workflow includes auditing your footprint, running nexus checks, registering where needed, configuring Amazon Seller Central, using automation tools (like Avalara, TaxJar), maintaining documentation, and re-evaluating quarterly. International sellers have additional steps, often requiring EINs and U.S. payment methods. State rules vary significantly, so sellers should consult state Department of Revenue (DOR) guidance, especially for states with large Amazon footprints (e.g., CA, TX, FL, NY, WA, MI, IL, NJ). The blog should include a plain-language overview of nexus types, FBA-specific risks, marketplace facilitator explanations with Amazon’s state list, state registration/filing nuances with examples, a practical compliance checklist, recommended automation tools, and links to resources like Amazon Seller Central help and state DOR pages.
