Illinois sales tax rates by ZIP code
Home-rule municipalities and several special districts stack in the Chicago area. Illinois routinely has multiple rates inside a single ZIP code.
Counts and the combined rate range are drawn from our October 2026 file. Rates change monthly.
What you actually have to charge in Illinois
Local jurisdictions add their own rate on top, so the rate you must actually charge is almost never the state rate.

What's in the Illinois rate file
Illinois data ships inside every edition — we do not sell single-state files. Each row carries the ZIP code, county and city name, the rate at each jurisdiction level, the combined total, and whether shipping is taxable. The higher editions add district reporting codes, FIPS codes, effective dates and sales tax holiday windows.

Worth knowing. A Retailers' Occupation Tax state with a dense layer of overlapping local jurisdictions, so rate determination usually needs the MyTax Tax Rate Finder rather than a ZIP lookup. Illinois publishes machine-readable rate files, which is unusual and useful.
Questions
Illinois sales tax questions
What is the sales tax rate in Illinois?
The statewide base rate is 6.25%. Local jurisdictions add their own rate on top, so the rate you must actually charge is almost never the state rate.
Is shipping taxable in Illinois?
Generally no. In Illinois a delivery charge is not taxable, and combining it with handling does not make it taxable.
That distinction catches people out, which is why our file carries both flags — TAX_SHIPPING_ALONE and TAX_SHIPPING_AND_HANDLING_TOGETHER — on every row, for the specific jurisdiction. Your system doesn't have to encode the rule.
How many sales tax jurisdictions are there in Illinois?
We track 896 bodies that actually levy a sales tax in Illinois — 86 counties, 505 cities and 305 special districts — across 1,568 IL ZIP codes. We count a county, city or district only where it charges something, not merely because it appears in the file.
