Amazon sellers often rely on the Fulfillment by Amazon program to manage logistics and shipping. While this system improves delivery speed and operational efficiency, it can also create complex tax obligations.
One of the most common compliance issues arises when Amazon stores seller inventory in multiple states. Inventory stored within a state may create physical nexus and trigger sales tax obligations.
Understanding how Amazon inventory storage creates nexus helps sellers identify potential compliance risks and manage tax obligations effectively. If you are unfamiliar with nexus rules, begin with the overview Economic Nexus Explained.
How Amazon Stores Seller Inventory
When sellers participate in Amazon FBA, they ship inventory to Amazon warehouses where products are stored until they are sold and shipped to customers.
Amazon manages inventory distribution across its fulfillment network. This network includes warehouses located throughout the United States.
Amazon may move inventory between warehouses to optimize delivery times and maintain inventory availability.
Examples of Amazon storage locations include:
- Regional fulfillment centers
- Sorting facilities
- Local delivery stations
- Distribution hubs
Because inventory may be stored in several states simultaneously, sellers may create nexus in multiple jurisdictions. You can learn more about inventory related nexus in Sales Tax Exposure From Inventory Storage.
Why Inventory Storage Creates Nexus
Sales tax nexus can arise when a business has physical presence within a state. Inventory stored in a warehouse qualifies as physical presence.
When Amazon stores seller inventory in a fulfillment center located within a state, that inventory may establish nexus.
Once nexus exists, the seller may be required to:
- Register for a sales tax permit
- Collect tax on taxable transactions
- File periodic tax returns
These obligations may apply regardless of sales thresholds. More details about physical nexus are explained in Physical Nexus vs Economic Nexus.
How Amazon Moves Inventory
Amazon frequently transfers inventory between warehouses to ensure fast delivery to customers. These transfers may occur automatically as part of Amazon’s fulfillment network.
As inventory moves between facilities, sellers may create nexus in additional states. Because sellers do not control inventory distribution, monitoring storage locations becomes important for compliance.
Amazon sellers can review inventory event reports and fulfillment center reports to identify warehouse locations where products have been stored.
Economic Nexus and Amazon Inventory
Even if inventory storage does not create nexus in a particular state, sellers may still create economic nexus through sales activity.
Economic nexus generally occurs when sales into a state exceed thresholds such as $100000 annually.
Both inventory nexus and economic nexus may apply simultaneously. To review nexus thresholds across states, visit Economic Nexus by State.
Businesses can estimate nexus exposure using the economic nexus calculator.
Marketplace Facilitator Collection
Most states require Amazon to collect and remit sales tax on behalf of marketplace sellers. While this simplifies tax collection for Amazon transactions, sellers may still have compliance responsibilities.
These responsibilities may include:
- Monitoring inventory locations
- Tracking nexus thresholds
- Evaluating sales activity outside the marketplace
A detailed explanation of marketplace rules is available in States With Marketplace Facilitator Sales Tax Laws.
How Sellers Monitor Inventory Nexus
Amazon sellers should review inventory reports regularly to identify where products are stored.
Important steps include:
- Checking fulfillment center inventory reports
- Reviewing inventory movement history
- Tracking warehouse locations across states
- Monitoring sales activity within each jurisdiction
These steps help sellers identify potential nexus obligations. Businesses can estimate potential liabilities using the sales tax exposure calculator.
Why Inventory Nexus Matters for Sellers
Inventory nexus is one of the most common reasons ecommerce sellers create sales tax obligations across multiple states. Because Amazon manages inventory distribution automatically, sellers may create nexus without realizing it.
Monitoring inventory storage and sales activity helps sellers remain compliant as their ecommerce businesses grow.
