Milwaukee County collects delinquent taxes for 18 suburban municipalities; the City of Milwaukee Treasurer collects City taxes.
- Assessment appeal

Wisconsin has no county homestead exemption. For the 2026 tax year, the Lottery and Gaming Credit is claimed on Form LC-100 through the local municipal or county treasurer for an owner-occupied primary residence; income-based Homestead Credit claims use Wisconsin DOR Schedule H or H-EZ with the applicable 2026 Wisconsin income-tax filing.
Senior relief
Wisconsin has no general age-based county property-tax exemption. Older or disabled homeowners may qualify for the income-limited Homestead Credit, Lottery and Gaming Credit, Veterans and Surviving Spouses Property Tax Credit, or WHEDA property-tax deferral loans, subject to each program's eligibility and filing rules. Milwaukee County also links Wisconsin property-tax credits for eligible disabled veterans and surviving spouses.
Valuation limits
No general parcel-level annual valuation cap identified in Wisconsin. Municipal assessments follow state market-value and uniformity requirements; Wisconsin levy limits cap aggregate local levies, not individual assessed-value growth, while state credits and relief programs reduce qualifying tax bills.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
