2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with Oceana County Equalization Department and County Treasurer.
Effective rate
no single countywide effective property-tax rate is published; Michigan property taxes are levied by local cities, townships, and villages and vary by millage district.
Statement mailing
official county sources reviewed do not publish a single countywide 2026 tax-bill mailing date; local units issue bills.
Payment deadline
2026 Michigan property-tax schedule: summer tax bills are generally issued July 1, 2026 and due September 14, 2026 unless a local charter provides another date; winter bills are generally issued December 1, 2026 and due February 14, 2027. Unpaid 2025 taxes were returned to county treasurers March 2, 2026 because March 1 was Sunday; a 4% administration fee and 1% monthly interest apply to delinquent taxes. Local-unit schedules control.
Valuation protest
2026 assessment appeals are filed with the city or township Board of Review. The organizational meeting is March 3, 2026; appeal meetings begin March 9, 2026, with a permitted local alternative on March 10 or 11; the March Board must finish by April 6, 2026. Local meeting times and petition procedures vary; further appeal to the Michigan Tax Tribunal follows statutory deadlines.
Critical payment warning
Do not assume a grace period.
The verified county 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 the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation 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.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment 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.
