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

For 2026, Amazon collects and remits Mississippi 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 Mississippi once those off-Amazon sales cross $250,000, and you may need Mississippi registration if FBA inventory is stored in-state.

Does Amazon FBA inventory in Mississippi 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 MS fulfillment-center activity. Whether Mississippi then requires a registration when a marketplace facilitator already collects on all your Mississippi orders is a per-state rule — some states want the registration for information reporting, others do not — so confirm Mississippi's position with the Mississippi Department of Revenue before you register or skip it.

Does Amazon collect Mississippi sales tax on my FBA orders?

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

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

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

What about direct-to-consumer sales outside Amazon?

Those are your responsibility. If your Shopify store or website sells into Mississippi above $250,000, you register independently.

Amazon collecting Mississippi sales tax on your FBA orders does not end your Mississippi 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 Mississippi can create.

Amazon FBA and sales tax in Mississippi

As of July 2026, Amazon FBA sales tax in Mississippi is three separate duties, not one: where Mississippi has a marketplace facilitator law Amazon calculates, collects, and remits the tax on the orders it facilitates; FBA inventory Amazon stores in a Mississippi fulfillment center can create physical nexus on its own; and you still register and file on your direct, non-Amazon sales into Mississippi once they cross $250,000.

Mississippi has a marketplace facilitator law, so Amazon calculates, collects, and remits Mississippi 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 Mississippi 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 Mississippi even if you never shipped there yourself. To see whether you actually hold units in Mississippi, pull the Inventory Event Detail report (Seller Central → Reports → Fulfillment) and filter for MS fulfillment-center codes; that report, not a guess, is what tells you whether Mississippi physical nexus is in play.

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

When you still need to file in Mississippi

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

Common Amazon-seller mistakes in Mississippi

Assuming marketplace facilitator status covers everything — if Amazon stored your inventory in Mississippi, 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 Mississippi sales tax return as taxable when they should be reported as marketplace-facilitated (non-taxable for you). State form boxes vary.

Mississippi nexus note

Mississippi sales and use tax nexus threshold: out-of-state businesses with Mississippi sales exceeding $250,000 over any twelve-month period are considered to have substantial economic presence effective July 1, 2018 and must register, collect, and remit tax. Mississippi uses a sales-only threshold — no transaction-count test. Remote sellers should measure sales on a rolling twelve-month basis rather than the current-or-prior-calendar-year framing used by many other states.
