Understanding Rock County Tax Rates

In Rock County, Wisconsin, the sales tax rate is a combination of the state base rate and any additional local taxes. Wisconsin imposes a 5% state sales tax, and Rock County adds a 0.5% county tax, resulting in a total combined rate of 5.5%. Some cities within the county may impose additional local taxes, so the final rate can vary slightly depending on your exact location.

Wisconsin also has a state income tax, which operates on a progressive system with four brackets ranging from 3.54% to 7.65%. Rock County does not levy an additional local income tax, so residents only pay the state income tax.
