# Registering for a Illinois sales tax permit

Illinois's state sales tax rate is 6.25%, local taxes come on top, and its remote seller threshold is $100,000 in sales, measured over the preceding 12 months (four quarters), checked quarterly. If your business has crossed it and needs a permit, we prepare and submit the Illinois registration through tax.illinois.gov/research/publications/pubs/retailers-overview-of-sales-and-use-tax/registering-your-business.html for $99, plus any state fee at cost.

## Illinois's threshold, in its own words

Since January 1, 2026 only the $100,000 gross receipts test applies; the 200-transaction test was removed. 6.25% is the state rate on general merchandise.

Illinois has a marketplace facilitator law, so sales through a marketplace that collects for you are handled by the marketplace.

Paperwork only: whether your sales count toward the threshold is a tax question for your preparer. State fees at cost.
