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 Tioga County Assessment Office.
Effective rate
2026 county, municipal, and school millage varies by taxing district; Tioga County publishes a 2026 millage schedule on its Assessment page.
Statement mailing
County/municipal tax bills are mailed March 1, 2026; school tax bills are mailed July 1, 2026, under Tioga County's official Important Dates schedule.
Payment deadline
December 31, 2026 is the final day to pay the Tax Collector; unpaid taxes are returned to Tax Claim on January 1, 2027. County/municipal and school tax years follow the Tioga County schedule.
Valuation protest
Annual assessment appeals may be filed July 1–September 1, 2026; property owners have 40 days from a Change of Assessment Notice. October 31, 2026 is the final hearing day for annual appeals.
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.
