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

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

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

Does Amazon collect Maine sales tax on my FBA orders?

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

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

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

What about direct-to-consumer sales outside Amazon?

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

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

Amazon FBA and sales tax in Maine

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

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

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

When you still need to file in Maine

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

Common Amazon-seller mistakes in Maine

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

Maine nexus note

Maine sales tax nexus and economic nexus threshold: Maine’s remote-seller trigger is sales-only. Under 36 M.R.S. §1754-B(1-B)(B), a person must register and collect Maine sales tax if its gross sales from delivery of tangible personal property or taxable services into Maine "in the previous calendar year or current calendar year exceeds $100,000" — there is no transaction-count prong. Read the 200-transaction figure you will find elsewhere with care: it comes from two provisions Maine has repealed. 36 M.R.S. §1951-B ("Collection of tax by remote sellers"), which set the original "$100,000 or at least 200 separate transactions" test, is repealed (PL 2019, c. 401, Pt. B, §21; PL 2019, c. 441, §7), and §1754-B(1-A) ("Persons presumptively required to register"), which carried the transaction presumption, is repealed by PL 2021, c. 181, Pt. B, §4 — the same chapter that replaced paragraph (B) with the sales-only test (PL 2021, c. 181, Pt. B, §5). Two widely used references had not caught up when this record was verified on 2026-08-10: Maine Revenue Services’ own "Guidance for Remote Sellers" page still describes the repealed §1951-B test, and the Streamlined Sales Tax Governing Board’s multistate remote-seller table still lists Maine at "$100,000 or at least 200 separate transactions." A small seller with many low-value Maine orders should not register on the transaction count alone. Marketplace facilitators are covered separately by §1754-B(1-B)(K): a facilitator registers once its Maine gross sales exceed $100,000, and that figure includes sales it facilitates for marketplace sellers as well as its own. Maine imposes a 5.5% state sales tax with no local sales tax. Maine Revised Statutes and Maine Revenue Services source data last retrieved 2026-08-10.
