How Pennsylvania Property Tax Appeals Usually Work
Deadline
Pennsylvania Appeal Deadlines Vary by County
Pennsylvania sets annual appeal deadlines county by county. Under the state assessment law, the default deadline is September 1, but a county may move it earlier, to no sooner than August 1, so many counties land on August 1 or September 1. The two largest jurisdictions run on their own calendars: Allegheny County’s annual appeal window for tax year 2027 is July 1 to September 1, 2026, and Philadelphia’s formal appeal to the Board of Revision of Taxes is due the first Monday of October, which is October 5, 2026. Always confirm your specific county’s deadline before you file.
Start With the Parcel
The county assessment record is where the assessed value, owner details, and property facts usually begin. Homespring uses the address step to orient the case before asking for more homeowner effort.
Evidence Matters More Than Frustration
A strong appeal usually depends on comparable sales, parcel detail accuracy, and any specific condition issues that affect value.
County Rules Still Control
Homespring can help homeowners organize the process, but the county record, the board’s filing steps, and the property’s facts still drive the outcome.
How Pennsylvania Appeals Work
- Confirm the county assessment record and assessed value first.
- File the county’s annual appeal application with the Board of Assessment Appeals by your county’s deadline; in Philadelphia, the formal appeal goes to the Board of Revision of Taxes.
- Gather comparable sales and evidence, keeping in mind the county’s Common Level Ratio, which can affect how assessed value compares to market value.
- If you disagree with the board’s decision, you can appeal to the county Court of Common Pleas, generally within 30 days.

Where to File and Where to Appeal Next
In most Pennsylvania counties, appeals are filed with the county Board of Assessment Appeals using that county’s annual appeal form. Allegheny County uses the Board of Property Assessment Appeals and Review, and Philadelphia uses the Board of Revision of Taxes, with the Office of Property Assessment also offering a separate First Level Review. If you disagree with the board’s decision, the next step is the county Court of Common Pleas. Homeowners can always appeal on their own for free; Homespring is for those who would rather have the comparable sales, evidence, and hearing handled for them.
