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

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

Does Amazon FBA inventory in Arizona create physical nexus?

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

Does Amazon collect Arizona sales tax on my FBA orders?

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

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

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

What about direct-to-consumer sales outside Amazon?

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

Arizona Amazon FBA Sales Tax Guide — 2026

Updated 2026-05-27

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

Amazon FBA and sales tax in Arizona

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

However, if Amazon stores your FBA inventory in a Arizona 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 Arizona

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

Common Amazon-seller mistakes in Arizona

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

Arizona nexus note

Economic nexus in Arizona triggers at $100,000 in gross sales delivered into Arizona in the current or prior calendar year. No transaction count threshold.
