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 in gross sales OR 200 transactions, and you may need Kentucky registration if FBA inventory is stored in-state.

Does Amazon FBA inventory in Kentucky create physical nexus?

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

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 in gross sales OR 200 transactions, you register independently.

Kentucky Amazon FBA Sales Tax Guide — 2026

Updated 2026-05-24

If your Amazon business sells $100,000 or 200 transactions into Kentucky in a calendar year, you have economic nexus and must register, collect, and remit Kentucky sales tax.

Amazon FBA and sales tax in Kentucky

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

However, if Amazon stores your FBA inventory in a Kentucky 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 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: through July 31, 2026, a remote retailer must register and collect Kentucky sales tax once it has $100,000 or more in gross receipts from sales into Kentucky OR 200 or more separate sales into Kentucky in the previous or current calendar year — meeting either test triggers the requirement (Kentucky Department of Revenue Wayfair guidance, HB 487; collections required beginning October 1, 2018). Effective August 1, 2026, House Bill 757 (2026 Regular Session, enacted over the Governor's veto) removes the 200-transaction test for both remote retailers and marketplace providers, leaving a $100,000 sales-only threshold that counts tangible personal property, digital property, and services delivered, transferred electronically, or provided to a Kentucky purchaser; sellers 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 extends Kentucky sales and use tax to data brokering services beginning August 1, 2026. Direct-to-consumer sales outside any marketplace remain the seller's own collection responsibility once nexus is met.
