Tax bills & filing dates
These are the dates and qualifications recorded in the directory. Confirm your tax year and current deadline with the official office and your property’s notice.
- Tax bill mailing
- December 2026 — local municipal treasurers mail tax bills in December; no exact 2026 mailing day was published by Columbia County.
- Payment deadline
- For 2026 Wisconsin property taxes payable in 2027: full payment or the first installment is due January 31, 2027 to the local municipal treasurer; the second installment is due July 31, 2027 to the county treasurer. Late payments become delinquent under Wisconsin Statutes §§74.11, 74.12, and 74.85 and accrue statutory interest and penalty.
- Assessment appeal
- Exact 2026 dates are municipality-specific, not countywide. Wisconsin DOR's 2026 Open Book/Board of Review calendar says sessions generally occur late May through mid-June; written or oral notice of intent is due at least 48 hours before the first Board of Review meeting, and the written PA-115A objection is due before or during the first two hours of that meeting.
Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
2026 Wisconsin Homestead Credit claims are filed with the 2026 income-tax return using Schedule H or Schedule H-EZ; age 62+ at the end of the claim year is one qualifying route. For the 2026 Lottery and Gaming Credit, use Form LC-100 with the local municipal or county treasurer for a primary residence as of January 1, 2026; if the credit is missing from the bill, the ordinary local claim deadline is January 31 after the bill is issued.
Senior relief
Wisconsin has no general age-based county homestead exemption. Qualifying older or disabled homeowners may use the state Homestead Credit, Lottery and Gaming Credit, Veterans and Surviving Spouses Property Tax Credit, and WHEDA property-tax deferral loan programs, subject to each program's eligibility and filing rules.
Valuation limits
No general local annual parcel-value growth cap was identified. Wisconsin municipalities assess property under state uniformity and market-value rules; state levy limits cap aggregate levies and property-tax credits provide relief, but neither caps an individual parcel's assessed-value growth.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
