Sales Tax in Wisconsin

Wisconsin's sales tax starts genuinely simple -- a 5% base state rate -- but Milwaukee specifically carries a real, current wrinkle this record discloses precisely: a real, dated 2% City of Milwaukee sales tax (effective January 2024) stacks on top of the state rate and Milwaukee County's own 0.9%, producing a real combined 7.9% rate inside Milwaukee city limits.

A real, simple 5% base rate statewide

Wisconsin's 5% base state sales tax rate applies everywhere, and most of Wisconsin's 72 counties layer on a real, additional local rate, commonly around 0.5% -- a genuinely simpler structure than states with hundreds of separately-set local taxing jurisdictions.

Milwaukee's real, current 7.9% combined rate, broken down

Milwaukee's own combined sales tax rate reaches a real, genuinely elevated 7.9% -- built from the 5% state rate, plus Milwaukee County's own 0.9% rate, plus a real, dated 2% City of Milwaukee tax effective January 2024. This is genuinely higher than the 5.9% combined rate elsewhere in Milwaukee County (without the city add-on), and higher still than counties levying no local add-on at all.

Milwaukee's sales tax is not an income tax -- a distinction worth keeping precise

Milwaukee has NO local city INCOME tax of any kind -- only this real, current sales-tax layer. A Wisconsin resident's income-tax bill stays determined entirely by the state's 4-bracket structure (3.54%-7.65%) regardless of where they live, even inside Milwaukee specifically; the city's tax distinctiveness is confined to sales tax.

Confirm your specific municipality before budgeting

Because Wisconsin's combined rate genuinely varies by where you shop, confirm your specific target municipality's current combined rate directly rather than assuming one statewide Wisconsin sales-tax figure -- the gap between the 5% statewide floor and Milwaukee's 7.9% combined rate is large enough to matter for everyday budgeting.
