Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Allegheny County Office of Property Assessments and Treasurer's Office.
Relief programs
The filing guidance for this county is: the official county source reviewed lists multiple abatements and exemptions with program-specific deadlines; no single 2026 countywide homestead application deadline was published on the reviewed page. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationAllegheny County Act 77 Senior Citizen Property Tax Relief: qualifying homeowners age 60 or older who have owned and occupied the home for at least 10 years and whose total gross household income is no greater than $30,000 may receive a 30% county-tax discount. The 2026 application deadline is June 30, 2026.
Pennsylvania has no general statewide annual assessed-value cap. County assessments are governed by uniformity requirements and Pennsylvania common-level-ratio rules; local Clean and Green preferential assessment and homestead/farmstead exclusions may change taxable value but are not a general cap.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: For tax year 2026, the annual assessment appeal window was July 1, 2025 through September 2, 2025.

If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
