Tax relief and valuation review

Protect your exemption and appeal rights.

A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Columbia County Treasurer and Land Information Department / Real Property Lister; municipal assessors perform local valuation.

Protect your exemption window

Homestead and senior-relief filings often follow a statutory assessment calendar. Missing a filing window can defer savings until the next tax year, so verify the current requirements with Columbia County Treasurer and Land Information Department / Real Property Lister; municipal assessors perform local valuation before submitting.

Verified filing guidance: 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.

What the local record says

Homestead filing

The filing guidance for this county is: 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.

Open homestead application

Senior citizen tax 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 cap or growth limit

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.

Appealing an assessment

Build the objection around evidence and the notice date.

Calendar the window

Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.

Assemble support

Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.

File and preserve proof

Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.

The verified protest guidance for this county is: 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. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
