Manitowoc County, Wisconsin property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Manitowoc County Treasurer and Planning & Zoning Real Property Lister; municipal assessors perform local valuation.
Rate context
Confirmno single countywide effective rate is published; Wisconsin property-tax rates vary by municipality, school district, and other taxing jurisdictions.
Statement mailing
PublishedThird Monday in December 2026; Manitowoc County says bills are created by the County Treasurer and given to local municipal treasurers to mail, except City of Manitowoc and City of Two Rivers current-year taxes.
Payment deadline
PublishedFor 2026 taxes payable in 2027, the first installment or full payment is due January 31, 2027 to the local treasurer; the second installment is due July 31, 2027 to Manitowoc County. A missed January installment becomes immediately delinquent and accrues 1% interest per month.
Valuation protest
Published2026 Open Book and Board of Review dates are municipality-specific; no single countywide date is published. Wisconsin procedure requires written or oral notice of intent at least 48 hours before the first Board of Review meeting, and the written objection (PA-115A) is generally due within the first two hours of that meeting, subject to statutory exceptions.
Do not assume a grace period.
The reviewed record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat a published payment deadline as a hard operational date and retain your receipt or confirmation number.
From assessment to collection
01Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
02Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
03Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
