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 Mifflin County Assessment Office.
Effective rate
official 2026 millage rates are district-specific; no single countywide effective average is published.
Statement mailing
official Mifflin County sources reviewed publish 2026 millage rates and the current tax-collector list but not one countywide bill-mailing date.
Payment deadline
local tax collectors administer current 2026 bills and official county sources reviewed do not publish one countywide discount, face, or penalty schedule.
Valuation protest
official Mifflin County Assessment sources reviewed do not publish a verified 2026 annual assessment-appeal filing date; the assessment office and any change notice control.
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.
