Pennsylvania Property Tax Assessment Appeal Letter Generator

If you own property in Pennsylvania and believe your county assessment is too high, you have the right to appeal. Pennsylvania uses a unique system where assessed values are tied to a 'common level ratio' (CLR) published annually by the State Tax Equalization Board. Because counties reassess infrequently—some haven't done so in decades—many properties are over-assessed compared to current market values. A well-drafted appeal letter to your county Board of Assessment Appeals is the first step toward lowering your tax bill. Missing the strict statutory deadline (typically September 1) means waiting another full year. This tool helps Pennsylvania homeowners and commercial property owners create a clear, evidence-based appeal letter that complies with the Consolidated County Assessment Law.

Pennsylvania's property tax assessment system is governed primarily by the Consolidated County Assessment Law (53 Pa.C.S. §§ 8801-8868), which applies to counties of the second class A through eighth class. Philadelphia and Allegheny County operate under separate statutory frameworks (the First Class City Business Tax Reform Act and the Second Class County Assessment Law, respectively). Under Pennsylvania law, real property must be assessed at a 'predetermined ratio' of actual market value, but because reassessments are infrequent, the State Tax Equalization Board (STEB) publishes an annual Common Level Ratio (CLR) for each county that adjusts assessments to reflect current market conditions. To win an appeal, the property owner generally must prove the property's current fair market value, then apply the county's CLR to determine the correct assessed value. If the existing assessment exceeds market value times the CLR, the assessment must be reduced. Evidence typically includes recent comparable sales, a professional appraisal, income/expense data for commercial properties, photographs showing condition issues, and proof of recent purchase price. The Pennsylvania Supreme Court in Downingtown Area School District v. Chester County Board of Assessment Appeals confirmed that taxpayers may use the CLR to challenge assessments even when no countywide reassessment has occurred. Appeals proceed first to the County Board of Assessment Appeals, then to the Court of Common Pleas (de novo review), and ultimately to the Commonwealth Court. School districts and municipalities also have the right to file appeals, though Act 52 of 2017 limited reverse appeals targeting recently sold properties.

A Pennsylvania property tax appeal letter serves two purposes: it formally initiates the administrative appeal with the County Board of Assessment Appeals, and it puts the taxing authority on notice of your specific factual and legal grounds. The letter should identify the property by parcel number, state the current assessed value, state your opinion of fair market value, apply the current Common Level Ratio to calculate the requested assessed value, and attach supporting evidence. Because Pennsylvania appeals are decided on a 'clear, precise, and indubitable' evidentiary standard at the Common Pleas level, building a strong record at the Board hearing matters. Cite recent arms-length comparable sales within the same neighborhood and tax year, note any property defects (structural, environmental, functional obsolescence), and reference the STEB-published CLR for your county and tax year. For commercial properties, include capitalization-rate analyses or income approach data. Request a hearing date, identify any representative (attorney, appraiser, or authorized agent), and preserve your right to appeal further to the Court of Common Pleas within 30 days of the Board's decision. A clear, evidence-backed letter often resolves disputes informally—county boards regularly issue stipulated reductions before hearings when the taxpayer's submission demonstrates a strong CLR-based case.

Annual appeal deadlines are September 1 in most Pennsylvania counties, but Allegheny County uses March 31 and some counties use August 1—always confirm with your local Board of Assessment Appeals. Interim appeals (after a new assessment notice) must be filed within 40 days of the notice date. Filing fees vary by county, typically $25-$100 for residential and higher for commercial properties. Appeals from the Board of Assessment Appeals to the Court of Common Pleas must be filed within 30 days of the Board's mailed decision. Pennsylvania's small claims/Magisterial District Court limit of $12,000 does not apply to assessment appeals, which are heard exclusively in the Court of Common Pleas. Property owners may represent themselves before the Board, but corporations generally need counsel in court.
