A property tax rate above state and national medians

Sun Prairie's median effective property tax rate (1.88%, Ownwell) runs above both Wisconsin's own 1.43% statewide median and the 1.02% national median -- a real, disclosed fact reflecting Wisconsin's genuinely elevated statewide property-tax character.

Wisconsin's 4-bracket income tax, with no local layer

Wisconsin's real, 4-bracket progressive state income tax (3.50%, 4.40%, 5.30%, and a top rate of 7.65% on income over $315,310 for single filers in 2026) applies in Sun Prairie exactly as it does statewide, with no local or county piggyback layer.

A 5.5% combined sales tax

Dane County's combined sales tax rate runs 5.5% (Wisconsin's 5.0% state rate plus the county's own 0.5% rate), applying uniformly across Sun Prairie.

Statewide insurance costs, genuinely below several neighbors

No Sun Prairie-specific homeowners-insurance premium figure was found this pass -- Wisconsin's statewide average ran a real, disclosed $1,367-$1,897/year (midpoint ~$1,650), genuinely below Michigan, Minnesota, Illinois, and Iowa.
