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

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

Does Amazon FBA inventory in Illinois create physical nexus?

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

Does Amazon collect Illinois sales tax on my FBA orders?

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

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

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

What about direct-to-consumer sales outside Amazon?

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

Illinois Amazon FBA Sales Tax Guide — 2026

Updated 2026-05-22

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

Amazon FBA and sales tax in Illinois

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

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

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

Common Amazon-seller mistakes in Illinois

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

Illinois nexus note

Illinois sales tax nexus and economic nexus threshold: beginning January 1, 2026, a remote retailer is subject to Illinois state and local Retailers' Occupation Tax when it has $100,000 or more in cumulative gross receipts from sales of tangible personal property to Illinois purchasers during the lookback period. The prior 200-transaction threshold applied from 2021 through 2025 but no longer applies for 2026 and later periods. Remote retailers and marketplace facilitators determine the threshold quarterly for the preceding 12-month period, and destination-based local ROT generally applies when the sale is sourced outside Illinois.
