How does Amazon FBA sales tax work in Missouri in 2026?

For 2026, Amazon collects and remits Missouri sales tax on your FBA and MFN orders as a marketplace facilitator. You are still responsible for any direct-to-consumer or Shopify sales into Missouri once those off-Amazon sales cross $100,000, and you may need Missouri registration if FBA inventory is stored in-state.

Does Amazon FBA inventory in Missouri create physical nexus?

Storing inventory in a state is the classic physical-presence trigger across US states, and it applies regardless of sales volume. Pull your Amazon Inventory Event Detail report and look for MO fulfillment-center activity. Whether Missouri then requires a registration when a marketplace facilitator already collects on all your Missouri orders is a per-state rule — some states want the registration for information reporting, others do not — so confirm Missouri's position with the Missouri Department of Revenue before you register or skip it.

Does Amazon collect Missouri sales tax on my FBA orders?

Yes — Amazon is a marketplace facilitator in Missouri and collects and remits Missouri sales tax on your FBA and MFN sales automatically.

Do I still need to register in Missouri as an FBA seller?

If Amazon stores your FBA inventory in Missouri, you may have physical nexus and need to register for informational filing. Check your Amazon inventory reports for MO distribution.

What about direct-to-consumer sales outside Amazon?

Those are your responsibility. If your Shopify store or website sells into Missouri above $100,000, you register independently.

Amazon collecting Missouri sales tax on your FBA orders does not end your Missouri obligations. This guide separates the three that remain in 2026 — marketplace collection, your own registration duty, and the physical nexus that FBA inventory stored in Missouri can create.

Amazon FBA and sales tax in Missouri

As of July 2026, Amazon FBA sales tax in Missouri is three separate duties, not one: where Missouri has a marketplace facilitator law Amazon calculates, collects, and remits the tax on the orders it facilitates; FBA inventory Amazon stores in a Missouri fulfillment center can create physical nexus on its own; and you still register and file on your direct, non-Amazon sales into Missouri once they cross $100,000.

Missouri has a marketplace facilitator law, so Amazon calculates, collects, and remits Missouri sales tax on the FBA and MFN orders it facilitates for you. You do not collect tax on those transactions yourself.

Separately, if Amazon stores your FBA inventory in a Missouri warehouse, you may have physical nexus — independent of the economic threshold. Whether that alone obliges you to register when a facilitator already remits the tax is a per-state question; several states say yes for information reporting.

The trap is that you don’t choose where your units sit. Amazon’s Inventory Placement Service can distribute one shipment across fulfillment centers in dozens of states, and it can move stock between them without asking you — so FBA inventory can appear in Missouri even if you never shipped there yourself. To see whether you actually hold units in Missouri, pull the Inventory Event Detail report (Seller Central → Reports → Fulfillment) and filter for MO fulfillment-center codes; that report, not a guess, is what tells you whether Missouri physical nexus is in play.

Whether Missouri requires a registration when a facilitator already remits is a per-state rule — confirm your position with the Missouri Department of Revenue before you register or skip it.

When you still need to file in Missouri

You sell direct-to-consumer from your own store outside Amazon (Shopify, your website) into Missouri.
You have inventory stored in a Missouri FBA center (check your Amazon Seller Central inventory reports by state).
You sell wholesale, dropship, or run retail trade shows in Missouri.
State requires an information return even for marketplace-only sales (rules vary).

Common Amazon-seller mistakes in Missouri

Assuming marketplace facilitator status covers everything — if Amazon stored your inventory in Missouri, some states still want a registration on file.
Double-collecting when you sell the same SKU via Amazon AND your own Shopify store. Amazon collects; Shopify collects. Both remit. The buyer pays tax twice. Audit your setup.
Reporting marketplace-facilitated sales on your Missouri sales tax return as taxable when they should be reported as marketplace-facilitated (non-taxable for you). State form boxes vary.

Missouri nexus note

Missouri sales tax nexus and economic nexus threshold: remote sellers and marketplace facilitators that sell tangible personal property into Missouri must collect and remit vendor's use tax when gross receipts from taxable Missouri sales exceed $100,000. Missouri uses a sales-only threshold -- no transaction-count test. The Department of Revenue FAQ says sellers check at the end of each calendar quarter using the preceding 12-month period, and collection is required no later than three months after the quarter in which the threshold is crossed. Marketplace-only sellers do not collect Missouri vendor's use tax themselves, but sellers with both marketplace and independent sales count marketplace-facilitated receipts toward the $100,000 threshold and collect on their non-marketplace sales once the threshold is met.
