Wisconsin has some of the highest property taxes in the Midwest, with an average effective rate well above the national average. Property taxes fund a significant portion of local government and school district budgets, and the state has implemented levy limits to control the growth of property tax collections.

How Wisconsin Property Tax Works
Full Value Assessment
Wisconsin requires all property to be assessed at 100% of fair market value. The Department of Revenue conducts an annual equalized value determination to ensure that all municipalities maintain assessments near the statutory standard. If a municipality’s assessment level deviates significantly from 100%, the state adjusts (equalizes) the values for state aid and tax distribution purposes.
Levy Limits
Wisconsin imposes levy limits on municipalities and counties, generally capping the allowable increase in property tax levies to the percentage of net new construction value plus any applicable adjustments. School districts have separate revenue limits that restrict combined state aid and property tax revenue per student.
Tax Bill Components
A typical Wisconsin property tax bill includes levies from four to five taxing jurisdictions:
| Taxing Jurisdiction | Typical Share of Bill |
|---|---|
| School district | ~45-55% |
| Municipality (city/village/town) | ~20-25% |
| County | ~15-20% |
| Technical college | ~5-8% |
| Special districts/state | ~1-3% |
Exemptions and Credits
- Lottery and Gaming Credit: Applied automatically to the property tax bill for primary residences. The credit amount varies annually but has been approximately ~$218 per parcel in recent years.
- School Levy Tax Credit: Also applied automatically to tax bills based on school district levy amounts. The credit reduces the total tax by approximately ~$200 to ~$400 per parcel depending on the district.
- First Dollar Credit: A credit applied to each parcel of land (including non-residential parcels) based on the statewide average school and technical college net mill rate applied to a minimum value.
- Homestead Credit: Wisconsin offers an income-based property tax credit for homeowners and renters with household income under ~$24,680. The maximum credit is ~$1,168. Claimed on the Wisconsin income tax return (Schedule H or H-EZ).
- Veterans and Surviving Spouses Property Tax Credit: Wisconsin veterans with a service-connected disability rating of ~100% may receive a full property tax exemption on their primary residence. Surviving spouses may also qualify.
- Agricultural Use Value Assessment: Farmland is assessed at its use value for agricultural purposes rather than market value, typically resulting in significantly lower assessments.
- Manufacturing Property Exemption: Manufacturing personal property and machinery are exempt from local property taxes (the state reimburses municipalities for the lost revenue).
Comparison to Neighboring States
| State | Avg. Effective Rate | Median Tax Paid | Assessment Ratio |
|---|---|---|---|
| Wisconsin | ~1.61% | ~$3,864 | 100% |
| Minnesota | ~1.11% | ~$3,386 | Classification system |
| Iowa | ~1.52% | ~$2,700 | Varies by class |
| Illinois | ~2.08% | ~$5,100 | 33.3% (varies) |
| Michigan | ~1.38% | ~$2,800 | 50% (SEV) |
Wisconsin’s effective rate is higher than Minnesota and Michigan but below Illinois. The state’s reliance on property taxes to fund schools contributes to the elevated rates.
Tips for Managing Wisconsin Property Taxes
- Verify your assessment by comparing it to recent comparable sales. Wisconsin assessments should reflect full market value — if your assessed value is more than ~10% above market value, consider an objection.
- File a formal objection with your Board of Review, typically held in May. You must provide evidence such as recent sales data, appraisals, or documentation of property condition issues.
- Claim the Homestead Credit on Schedule H of your Wisconsin income tax return if your household income is below ~$24,680. Both homeowners and renters qualify.
- Confirm credits are applied — check your tax bill to ensure the Lottery and Gaming Credit, School Levy Tax Credit, and First Dollar Credit appear. The Lottery Credit requires filing a claim with your municipality.
- Understand levy limits — property tax increases are constrained by state law, so large spikes are generally due to assessment increases or referenda rather than unchecked rate growth.
- Explore use value assessment if you own agricultural land, as farmland assessed at use value can have dramatically lower property taxes.
- Factor property taxes into your federal return — deduct up to ~$10,000 under the SALT cap. For details, see the federal income tax guide.
