Generate a Pennsylvania over-assessed property value challenge letter. Dispute unfair tax assessments under PA law with deadlines, statutes, and proven strategy.
Generate My Letter — $19If you own property in Pennsylvania and believe your county has assessed it for more than it's actually worth, you have the legal right to challenge that assessment. Pennsylvania's Consolidated County Assessment Law gives property owners a clear path to appeal an over-assessed value, but the process is deadline-driven and document-heavy. A well-drafted challenge letter sent to your county Board of Assessment Appeals is often the first and most important step. It puts the county on notice, frames your evidence, and preserves your right to a formal hearing. Because Pennsylvania uses a Common Level Ratio to convert market value into assessed value, even small valuation errors can cost you hundreds or thousands of dollars per year in overpaid property taxes.
Pennsylvania property tax assessments are 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. Allegheny County and Philadelphia operate under their own assessment statutes, but the appeal principles are similar. Under 53 Pa. C.S. § 8842, county assessors must value property at its actual fair market value as of a specified base year. That market value is then multiplied by the county's predetermined ratio or, on appeal, by the State Tax Equalization Board's Common Level Ratio (CLR) to produce the taxable assessed value.
A property owner who believes the assessed value exceeds fair market value—or that the resulting assessment exceeds what the CLR would produce—may file an annual appeal under 53 Pa. C.S. § 8844. The Board of Assessment Appeals must hear the appeal and issue a written decision. At the hearing, the county initially presents the assessment, but the burden then shifts to the taxpayer to show, by competent evidence, that the property's fair market value is lower. Acceptable evidence includes recent appraisals, comparable sales, purchase price, income/expense data for commercial property, and photographs of physical defects.
If the Board denies relief, the owner may appeal de novo to the Court of Common Pleas within 30 days under 53 Pa. C.S. § 8854. The court will hear new evidence and apply the CLR for the appropriate tax year. Uniformity is also a constitutional requirement under Article VIII, Section 1 of the Pennsylvania Constitution, meaning similar properties must be assessed similarly. Demonstrating non-uniform treatment compared to neighboring properties can be a powerful additional argument supporting a reduction.
A Pennsylvania over-assessment challenge letter serves two purposes: it formally initiates or supplements your appeal to the county Board of Assessment Appeals, and it signals to the county solicitor that you are prepared to escalate to the Court of Common Pleas if necessary. The letter should be sent by certified mail to the Chief Assessor and the Board of Assessment Appeals before the statutory deadline (generally August 1 or September 1, depending on the county).
An effective letter identifies the parcel by tax map number, states the current assessed value and your opinion of fair market value, and applies the current Common Level Ratio published by STEB to show the correct assessment. Attach supporting evidence: a recent appraisal, MLS comparable sales within the last 12 months, a settlement statement if you bought recently, or contractor estimates documenting condition issues. Cite 53 Pa. C.S. § 8844 and reference the constitutional uniformity clause if neighboring comparable properties are assessed lower.
Close by demanding a specific reduced assessment, requesting a hearing date, and reserving the right to appeal to the Court of Common Pleas under 53 Pa. C.S. § 8854. Many counties resolve clearly meritorious appeals informally after receiving a well-documented letter, avoiding the need for a contested hearing. Even when a hearing is required, the letter creates a written record that frames your case, locks in your evidence, and demonstrates to the Board that you are organized and credible. Keep the tone professional and factual—aggressive language rarely helps before an administrative board.
Filing fees vary by county, typically ranging from $0 to $100 for residential appeals and higher for commercial properties. The annual appeal deadline is August 1 in most counties and September 1 in others; Allegheny County uses March 31. Interim appeals (after a new assessment notice) must be filed within 40 days of the notice. Hearings are informal and held before the Board of Assessment Appeals. Appeals to the Court of Common Pleas must be filed within 30 days of the Board's decision and require payment of court filing fees (generally $100–$300). Pennsylvania does not use small claims court for assessment appeals—the $12,000 small claims limit does not apply. You may represent yourself, but corporations and LLCs generally must appear through counsel in Common Pleas Court.
Property tax in Pennsylvania is governed by the Consolidated County Assessment Law (Title 53, Chapter 88); appeal procedure at Section 8844 (53 Pa.C.S. § 8801 et seq. (appeals: 53 Pa.C.S. § 8844)). Assessment cycle: Base-year assessment system: counties assess at a fixed base-year value and are not required to reassess on a set statewide cycle; STEB certifies a new Common Level Ratio annually (effective July 1 through June 30) to relate base-year assessed values to current market values. Assessed value: Common Level Ratio (CLR) published annually by the State Tax Equalization Board (STEB) for each of the 67 counties. CLR is the median ratio of assessed value to market value from STEB's annual sales-ratio study. When the CLR varies by more than 15% from the county's established predetermined ratio, the board must apply the CLR to the proven market value.
County Board of Assessment Appeals / Board of Revision of Taxes (assessment appeals); State Tax Equalization Board (STEB) under the PA Department of Community & Economic Development (Common Level Ratios); county Tax Claim Bureau (tax sales); PA Department of Revenue (Property Tax/Rent Rebate). The window to act is short — set by each county; the annual appeal deadline in most counties is August 1 (some run to September 1 or October 1; Allegheny County 2027 deadline is September 1, 2026). Interim/change-of-assessment appeals: generally 40 days from the mailing date of the notice.
A recent change to watch: For 2026, STEB-published Common Level Ratios and Allegheny County-specific changes were highlighted as creating appeal opportunities (particularly for commercial property) where revised ratios lower the effective assessment; no specific statewide legislative reform to the assessment-appeal statute was verified.
How your value is assessed: Common Level Ratio (CLR) published annually by the State Tax Equalization Board (STEB) for each of the 67 counties. CLR is the median ratio of assessed value to market value from STEB's annual sales-ratio study. When the CLR varies by more than 15% from the county's established predetermined ratio, the board must apply the CLR to the proven market value.
Evidence that works: Credible evidence of fair market value: recent comparable sales, the property's own recent sale price, independent/fee appraisals, income and expense data for income-producing property, and photographs/documentation of condition.
Appeal deadline: Set by each county; the annual appeal deadline in most counties is August 1 (some run to September 1 or October 1; Allegheny County 2027 deadline is September 1, 2026). Interim/change-of-assessment appeals: generally 40 days from the mailing date of the notice.
First-level appeal: Written appeal to the county Board of Assessment Appeals (in Philadelphia, the Board of Revision of Taxes), which schedules a hearing and issues a decision.
Next-level appeal: Appeal to the county Court of Common Pleas (de novo); Allegheny and Philadelphia are subject to distinctive statutory provisions.
Grounds you can raise: The property's fair market value is overstated (over-assessment), and/or the assessment is non-uniform relative to comparable properties / the county's common level ratio; the appellant bears the burden of proving fair market value.
Exemptions to claim: Homestead/Farmstead Exclusion reduces the taxable assessed value of an owner-occupied primary residence (lowering school district taxes); full real estate tax exemption for veterans honorably discharged and rated 100% permanently service-connected disabled; state-funded Property Tax/Rent Rebate for homeowners age 65+, widows/widowers age 50+, and disabled residents age 18+ with household income up to $45,000 (rebates up to $1,000, file PA-1000 by June 30).
The hearing: Administrative hearing before the county Board of Assessment Appeals where the owner presents market-value evidence and the Board issues a decision; further review is de novo before the Court of Common Pleas.
First, written appeal to the county Board of Assessment Appeals (in Philadelphia, the Board of Revision of Taxes), which schedules a hearing and issues a decision.
If that fails, appeal to the county Court of Common Pleas (de novo); Allegheny and Philadelphia are subject to distinctive statutory provisions.
Mind the deadline: set by each county; the annual appeal deadline in most counties is August 1 (some run to September 1 or October 1; Allegheny County 2027 deadline is September 1, 2026). Interim/change-of-assessment appeals: generally 40 days from the mailing date of the notice.
