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

For 2026, Amazon collects and remits Kentucky 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 Kentucky once those off-Amazon sales cross $100,000, and you may need Kentucky registration if FBA inventory is stored in-state.

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

Does Amazon collect Kentucky sales tax on my FBA orders?

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

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

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

What about direct-to-consumer sales outside Amazon?

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

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

Amazon FBA and sales tax in Kentucky

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

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

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

When you still need to file in Kentucky

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

Common Amazon-seller mistakes in Kentucky

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

Kentucky nexus note

Kentucky sales tax nexus and economic nexus threshold: since August 1, 2026, Kentucky uses a sales-only threshold — a remote retailer must register and collect Kentucky sales tax once it has $100,000 or more in gross receipts from sales into Kentucky in the previous or current calendar year, counting tangible personal property, digital property, and services delivered, transferred electronically, or provided to a Kentucky purchaser. House Bill 757 (2026 Regular Session, enacted over the Governor's veto) removed the former 200-transaction test for both remote retailers and marketplace providers effective August 1, 2026; through July 31, 2026 either the $100,000 receipts test or 200 or more separate Kentucky sales triggered registration (Kentucky Department of Revenue Wayfair guidance, HB 487; collections required beginning October 1, 2018). Sellers that registered solely because of transaction volume should review whether they can deregister under Kentucky's trailing-nexus rules. Kentucky's marketplace facilitator law (HB 354) has been effective since July 1, 2019 — Amazon, Etsy, eBay, and Walmart collect and remit Kentucky sales tax on facilitated sales, registering once for all third-party sellers per KRS 139.450 (procedure clarified by HB 249, effective July 1, 2021). Kentucky levies a flat 6% statewide sales tax with no local sales taxes, so the rate is identical at every Kentucky delivery address. HB 757 also extended Kentucky sales and use tax to data brokering services with effect from August 1, 2026. Direct-to-consumer sales outside any marketplace remain the seller's own collection responsibility once nexus is met.
