Amazon FBA and sales tax in Oregon

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

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

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

Common Amazon-seller mistakes in Oregon

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

Oregon nexus note

Oregon has no state or local general sales tax. Sellers do not need to register or collect sales tax on transactions shipped to Oregon customers. Oregon does impose a Corporate Activity Tax (CAT) on certain businesses with Oregon-source revenue over $1M, but this is not a sales tax.
