My FBA inventory is in the US. What should I include in a self-check?
Updated 2026-07-13
FBA can create a state footprint through inventory, while Amazon marketplace collection concerns the orders Amazon facilitates. Keep those two questions separate.
Inventory location is a separate fact from marketplace collection
A marketplace may collect tax for the transactions it facilitates. That does not erase the fact that your goods can be held in a state. Minnesota, for example, lists inventory stored in a fulfilment center in Minnesota as a reason a seller may need to register.
Minnesota is an example, not a nationwide shortcut. Each state decides how its registration and filing rules apply, so use your actual inventory-location record and verify the states involved.
Map where inventory is, not just where orders ship
Export or retain your FBA inventory-location reports and update them when fulfilment placement changes. Match each location to the relevant state's official registration guidance; do not infer an answer merely from your total US revenue.
This review also applies to third-party warehouses and other fulfilment arrangements. The location of the stock can be different from the delivery destination and from the marketplace that collected tax on an order.
Treat marketplace and direct orders as different streams
For Amazon marketplace orders, Amazon describes its own calculation and remittance role. For Shopify, wholesale or other direct orders, that marketplace collection path does not automatically apply.
Keep order data separated by channel, then review both inventory presence and direct sales state by state. That is more useful than treating FBA as simply “tax handled.”

FAQ
Does FBA inventory automatically create nexus in every state?+
Do not use an automatic rule. Inventory location is a physical-presence fact that can matter, so include it in a state-by-state self-check against current official guidance.
If Amazon remits marketplace tax, is there nothing else to do?+
Marketplace collection and your inventory footprint are separate facts. Keep both in the self-check and compare them with the relevant state's current guidance.
Why do direct-store sales matter here?+
Marketplace collection covers marketplace orders. Direct sales are not automatically on that same path, so record them separately in the self-check.
