Amazon operates one of the largest logistics networks in the world. Through the Fulfillment by Amazon program, sellers store products in Amazon warehouses that handle storage, packing, and shipping.<\/p>\n\n\n\n
While this system improves delivery speed, it also creates complex tax obligations. When inventory is stored in Amazon warehouses, sellers may create physical nexus in those states.<\/p>\n\n\n\n
Understanding how warehouse storage triggers nexus helps Amazon sellers manage compliance and avoid unexpected tax exposure.<\/p>\n\n\n\n
If you are unfamiliar with nexus rules, begin with the overview See: Economic Nexus Explained<\/a><\/strong>.<\/p>\n\n\n\n Warehouse nexus occurs when a business stores inventory in a facility located within a state.

As inventory moves between facilities, nexus may be created in additional states.<\/p>\n\n\n\n Monitoring warehouse reports helps sellers identify where inventory has been stored. Economic Nexus and Warehouse Nexus<\/p>\n\n\n\n Warehouse nexus may exist even when economic nexus thresholds have not been exceeded. Economic nexus is triggered by revenue thresholds such as $100000 in annual sales within a state.<\/p>\n\n\n\n Warehouse nexus is triggered by physical presence regardless of revenue. Because both forms of nexus may apply simultaneously, sellers must evaluate both inventory locations and sales activity.<\/p>\n\n\n\n To review economic nexus thresholds across states, visit See: Economic Nexus by State<\/a><\/strong>.<\/p>\n\n\n\n Businesses can estimate nexus exposure using the economic nexus calculator<\/a><\/strong>.<\/p>\n\n\n\n Most states require Amazon to collect sales tax for marketplace transactions.
