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?

Yes — Amazon storing your FBA inventory in a Missouri fulfillment center generally creates physical nexus regardless of sales volume. Pull your Amazon Inventory Event Detail report and look for MO fulfillment-center activity; if present, Missouri typically expects registration even when Amazon already collects sales tax on the facilitated orders.

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.

Missouri Amazon FBA Sales Tax Guide — 2026

Updated 2026-06-08

If your Amazon business sells $100,000 into Missouri in a calendar year, you have economic nexus and must register, collect, and remit Missouri sales tax.

Amazon FBA and sales tax in Missouri

Amazon is a marketplace facilitator in Missouri, which means Amazon calculates, collects, and remits sales tax on your FBA and MFN sales to Missouri buyers. You don't collect tax on those transactions yourself.

However, if Amazon stores your FBA inventory in a Missouri warehouse, you may have physical nexus — independent of the economic threshold. Some states will ask you to register anyway for information reporting.

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.
