How Do I Appeal My Property Tax Assessment in Pennsylvania?

An appeal makes sense when your assessed value is out of line with what comparable homes in your area are worth. Start by looking up your assessment on your county's website, then compare it to recent sales of similar homes. If your assessment is meaningfully higher than the value those sales support, you may have a case worth pursuing.

Not every assessment is worth appealing. If your number looks in line with your neighbors and the market, the time and effort may not pay off. Focus your energy on assessments that genuinely overshoot the comparables.

Every county in Pennsylvania runs its own appeal calendar, so the deadline is your first and most important check. Most counties hold an annual appeal window, often early in the year, and missing it means waiting for the next cycle. Find your county's assessment office online and confirm the filing date, forms, and fees.

The process typically starts with an informal review, then a formal hearing before the county's Board of Assessment Appeals, and finally an appeal to court if you disagree with the board. Most successful appeals are won at the informal or board stage.

Appeals are won with comparable sales, so build the strongest set you can. Collect recent closed sales of similar homes in your area, ideally three to five of them, with sale dates, prices, and basic details. If your home has a unique condition that lowers its value, document that too.

Photographs, a simple spreadsheet of the comparables, and your assessment notice are the essentials. You do not need an attorney for most board appeals, though hiring one can help in complex or high-value cases.

At the hearing, you present your evidence calmly and clearly, and the board asks questions. Explain that your assessment does not reflect the value supported by comparable sales, and hand over your documentation. Be respectful, stick to the data, and do not argue with the board or the assessor.

Boards decide based on the evidence before them, so the quality of your comparables matters more than the strength of your argument. If you win, the board issues a new assessment that applies going forward.
