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 Westmoreland County Tax Assessment Office.
Effective rate
2026 local and school millage varies by municipality and school district; Westmoreland County publishes a 2026 millage schedule with county general 25.00 mills and debt service 3.48 mills.
Statement mailing
the official 2026 county sources publish millage and tax-collector information but no uniform countywide tax-bill mailing date.
Payment deadline
local tax collectors administer current taxes; the County Tax Office/Tax Claim Bureau handles delinquent taxes, with electronic delinquent payment available through the official county-linked portal. No uniform 2026 discount/penalty schedule is published.
Valuation protest
August 1, 2026 for annual assessment appeals effective for the following tax year; a change-of-assessment appeal may be filed within 40 days of the mailing of the change notice.
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.
