In Pennsylvania the assessment on your bill is presumed correct until you prove otherwise — and the proof that counts is fair market value: recent sales of comparable homes around Philadelphia (a sales-comparison, cost, or income analysis), not a list of other properties' assessed values.
Appeals go to the Philadelphia Board of Revision of Taxes (BRT). There is no statewide deadline — each county sets its own annual cutoff, and missing it forecloses the annual appeal for that tax year. Philadelphia County's window: By Monday, October 5, 2026 (first Monday of October). Filing fee: $0 — no filing fee.
How to appeal in Philadelphia County — step by step
- 1
Confirm your county's exact deadline
Pennsylvania deadlines vary by county (commonly August 1, with different dates in Philadelphia and Allegheny County). The date on your assessment notice or the board's website controls — verify it before anything else.
- 2
Gather comparable sales
Three to five recent sales of similar homes are the backbone of a residential appeal. The board presumes the current assessment is correct, so the burden of proving market value is on you.
- 3
File the written appeal on the county's form
Each Pennsylvania county provides its own appeal form. Submit it to the Philadelphia Board of Revision of Taxes (BRT) before the deadline — a late annual appeal is out for the year.
- 4
Deliver your evidence in advance
Boards commonly require written evidence a fixed number of days before the hearing (about 10 days is typical) and may require multiple paper copies — check your county's hearing rules when you file.
- 5
Present your case at the hearing
Walk the board through your comparable sales and your conclusion about the home's fair market value. Evidence not provided in advance generally must be presented at the hearing itself — the board will not continue the hearing to accept late evidence.
- 6
Keep paying your tax bill
An appeal does not pause collection. Pay on time; a reduction is applied after the board rules.
