Office names and responsibilities vary even within a state. The directory classifies the reviewed Wisconsin records under the following administrative models.
Repeated guidance can reveal a common state calendar, but a county notice, local ordinance, installment schedule, or special program can still control an individual property. The entries below are shown only when the same reviewed wording appears in at least two Wisconsin records.
For 2026 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. Missed installments become delinquent after the statutory grace period and accrue Wisconsin statutory interest and penalty.
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.
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.
