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.
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.
Understanding how warehouse storage triggers nexus helps Amazon sellers manage compliance and avoid unexpected tax exposure.
If you are unfamiliar with nexus rules, begin with the overview See: Economic Nexus Explained.
What Warehouse Nexus Means
Warehouse nexus occurs when a business stores inventory in a facility located within a state. Because inventory represents physical presence, storing products in a warehouse can establish nexus and trigger sales tax obligations.
This means sellers may be required to
- Register for sales tax permits
- Collect sales tax on taxable transactions
- File periodic tax returns
These obligations apply even if the seller does not operate offices or employ workers in the state.
You can learn more about physical nexus rules in See: Physical vs Economic Nexus.
Amazon Fulfillment Center Network
Amazon’s fulfillment network includes hundreds of facilities across the United States.
These facilities include
- Regional fulfillment centers
- Sortation facilities
- Distribution warehouses
- Delivery stations
When sellers participate in FBA, Amazon may distribute inventory across these facilities to optimize shipping times. Because inventory may be stored in multiple locations, sellers may create nexus in several states simultaneously.
More details about Amazon inventory nexus are explained in See: Amazon Inventory Storage and Nexus.
Why Sellers Often Miss Warehouse Nexus
Amazon sellers frequently overlook warehouse nexus because inventory distribution is managed automatically by Amazon.
Sellers typically ship products to Amazon and do not control which fulfillment centers store their inventory. As inventory moves between facilities, nexus may be created in additional states.
Monitoring warehouse reports helps sellers identify where inventory has been stored. Economic Nexus and Warehouse Nexus
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.
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.
To review economic nexus thresholds across states, visit See: Economic Nexus by State.
Businesses can estimate nexus exposure using the economic nexus calculator.
Marketplace Facilitator Laws
Most states require Amazon to collect sales tax for marketplace transactions. These marketplace facilitator laws simplify tax collection but do not eliminate all compliance responsibilities.
Sellers may still need to
- Monitor inventory locations
- Evaluate nexus thresholds
- Register for sales tax permits in certain states
A detailed explanation of marketplace rules is available in See: States With Marketplace Facilitator Laws.
Managing Warehouse Nexus Risk
Amazon sellers should regularly review fulfillment center inventory reports to determine where products are stored.
Important steps include
- Monitoring inventory location reports
- Tracking warehouse distribution history
- Reviewing revenue by state
- Monitoring nexus thresholds regularly
These steps help sellers identify potential compliance obligations before exposure accumulates. Businesses can estimate potential liabilities using the sales tax exposure calculator.
