Illinois Sales Tax for Amazon Sellers

Illinois sales tax for Amazon sellers: the short answer

Marketplace facilitator status: Illinois has had marketplace facilitator (MF) law in effect since 2020. Illinois implemented marketplace facilitator law on January 1, 2020 (effective for collection January 1, 2021). Amazon collects all Illinois state + local taxes.

What this means for you as an Indian FBA seller: for all your Amazon US sales delivered to Illinois customers, Amazon collects the appropriate Illinois sales tax (state + applicable local) and remits to the state directly. You see the line items in your Seller Central report. You do not need to register, collect, or remit Illinois sales tax on Amazon sales.

Illinois sales tax rates

Illinois has a 6.25% state base rate. Chicago adds 1.25% city + 0.75% county + 1.75% RTA + 0.5% MPEA = 10.25-11% combined in central Chicago. Suburban Cook County typically 9-10%.

FBA fulfillment centers in Illinois

Illinois has 7+ Amazon FBA fulfillment centers in greater Chicago: Joliet (MDW2, MDW6, MDW7, MDW9), Romeoville (MDW8), Aurora (MDW4), Plainfield (MDW5). Central US fulfillment hub for the Midwest.

Marketplace facilitator rules: when you DO have Illinois obligations

Three scenarios where Amazon\'s MF coverage doesn\'t apply to you:

1. Selling outside Amazon: if you sell on your own Shopify store, eBay (not always MF), or wholesale to Illinois-based B2B buyers, you may have direct obligations once you cross the economic nexus threshold of $100K or 200 transactions.
2. Physical presence: if your LLC has a Illinois-based employee, office, or owned warehouse, that triggers physical nexus. Illinois sales tax registration is required regardless of channel.
3. Owned property & income tax: physical presence may also trigger Illinois state income tax obligations on the portion of profit attributable to the state.

If you do need to register

If one of the above applies, registration is via Illinois Department of Revenue at tax.illinois.gov. The process typically takes 10-14 business days and requires your EIN, LLC details, and operating-history information. Filing frequency depends on volume - monthly, quarterly, or annually.

Illinois-specific FBA notes

• Illinois's "Retailers' Occupation Tax" is the official name for sales tax. Functionally equivalent.
• Cook County (Chicago metro) has the most complex layered tax stack in the US. Amazon handles this perfectly.
• Illinois actively pursues "marketplace remote sellers" who use FBA but also sell off-Amazon. Register at threshold.
• Illinois has reciprocity with some states for sales tax - irrelevant for Indian-owned LLCs but useful to know.

Common questions

Does inventory at a Illinois FBA center create nexus?

Historically yes (physical presence). Post-MF laws, this distinction is largely moot for sales tax - Amazon collects regardless. For state income tax, inventory presence creates a weak nexus that Illinois generally does not pursue aggressively against foreign-owned LLCs whose only state contact is FBA inventory.

Do I need a Illinois seller\'s permit for Amazon FBA only?

No, for Amazon FBA-only operations. Illinois\'s MF law has Amazon as the registered remitter. You don\'t need your own permit unless you sell directly via other channels above threshold.

What about returns processed in Illinois?

Amazon\'s MF remittance covers full refund flows. The sales tax originally collected gets refunded automatically when the order refunds. No separate filing required on your part.
