Wisconsin sales tax rates by ZIP code
County and a small number of city taxes apply.
Counts and the combined rate range are drawn from our October 2026 file. Rates change monthly.
What you actually have to charge in Wisconsin
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 Wisconsin rate file
Wisconsin 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.

How local tax works in Wisconsin. State-collected. County, city, premier resort area and local exposition district taxes are all remitted to DOR, which distributes revenue to counties monthly.
Worth knowing. Beyond the state and county tax, Wisconsin layers on narrow local taxes that catch filers out — City of Milwaukee and Milwaukee County rates, premier resort area taxes in specific municipalities, and exposition district taxes on lodging, food and car rental. The rate lookup accepts full street addresses only for transactions dated 1 October 2023 or later.
Questions
Wisconsin sales tax questions
What is the sales tax rate in Wisconsin?
The statewide base rate is 5%. 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 Wisconsin?
Generally yes. In Wisconsin a delivery charge is taxable whether you bill it on its own or roll it in with handling.
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 Wisconsin?
We track 74 bodies that actually levy a sales tax in Wisconsin — 70 counties, 2 cities and 2 special districts — across 877 WI ZIP codes. We count a county, city or district only where it charges something, not merely because it appears in the file.
