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
- By the third Monday in December 2026 under Wisconsin law; the county source reviewed did not publish an exact 2026 mailing date.
- Payment deadline
- For 2026 taxes payable in 2027, Portage County taxes are collected in two installments due January 31, 2027 and July 31, 2027; some municipalities collect their own first installment and the City of Stevens Point handles its own parcels. Missed installments become delinquent after the statutory grace period and accrue 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; give written or oral notice of intent at least 48 hours before the first Board of Review meeting and file PA-115A within the first two hours of that meeting, subject to statutory exceptions.
Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
Wisconsin has no county homestead exemption. For the 2026 tax year, claim the Lottery and Gaming Credit on Form LC-100 through the local municipal or county treasurer for an owner-occupied primary residence as of January 1, 2026; 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. Qualifying older or disabled homeowners may use the income-limited 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.
