How to Appeal Your Pennsylvania Property Tax Assessment

Last updated May 18, 2026

·Independent Pennsylvania tax education

Appealing a Pennsylvania property tax assessment isn't complicated, but it is procedural. Miss the deadline and you wait a year. This step-by-step guide walks through the PA appeal process from notice to hearing.

Key takeaways

Every PA county has its own appeal process and deadline.
Most counties require appeals to be filed by August 1 or September 1.
Good evidence (recent comparable sales, photos, repair estimates) wins appeals.
Appeals are usually filed with the county Board of Assessment, not the state.

When a PA property tax appeal makes sense

Three common situations make a Pennsylvania property tax appeal worth the effort:

Your assessed value looks high relative to recent comparable sales. If three or four nearby, similar homes sold within the last year for well below your assessed value, you likely have a case.
You just bought the property below the assessed value. An arm's-length recent sale price is strong evidence of market value.
Your property has problems the assessor doesn't know about. Major condition issues, structural problems, or other factors that would lower a sale price.

Pennsylvania appeal deadlines

Each PA county sets its own annual appeal deadline. Common deadlines are August 1 or September 1. A few counties use a different date. Always confirm with your county's Board of Assessment or assessor's office.

What evidence to gather

The best evidence for a PA property tax appeal is recent comparable sales of similar homes in your neighborhood. Aim for at least three sales within the past 12 months. The closer in age, size, lot, and condition, the better.

Other useful evidence:

Photos of any condition issues (roof, foundation, water damage, outdated systems).
Repair estimates from licensed contractors.
Appraisal from a Pennsylvania-licensed appraiser (worth it for big differences).
Public information showing your house has less finished space than the assessor recorded.

Step-by-step appeal procedure

Find your county assessment notice. It typically lists the assessed value, the implied market value, and the appeal deadline.
Confirm the assessed value. Double-check the square footage, year built, lot size, and any noted improvements.
Compare similar properties. Use county assessor records, the county recorder of deeds, or a real estate agent for recent arm's-length sales.
Check the appeal deadline. Confirm with your county Board of Assessment and give yourself at least two weeks to prepare.
Gather evidence. Pull comparable sales, photographs, and any reports or appraisals.
File the appeal with the correct county office. Use your county's official appeal form. Many counties allow online filing.
Attend the hearing if required. Bring a written summary, copies of evidence, and any witnesses.
Keep records of all submissions. Save copies of the appeal form, evidence, and the board's decision.

What happens at the county hearing

Most PA county assessment hearings are short (often 10-15 minutes). You present your case, the board may ask questions, and a written decision usually follows by mail several weeks later.

Stay focused on value. The board does not adjust your tax rate. It only decides whether the assessed value is correct.

What to do after the decision

If the county Board of Assessment denies your appeal or grants only a partial reduction, you can usually appeal again to the Court of Common Pleas in your county. That stage is more formal and often warrants a Pennsylvania-licensed attorney or property tax consultant.

DIY vs hiring an attorney or consultant

Many homeowners handle PA assessment appeals themselves. For higher-value properties, commercial real estate, or appeals to the Court of Common Pleas, hiring a Pennsylvania-licensed attorney or property tax consultant is often worth it. See our guide to finding a PA tax professional and our tax attorney page for when an attorney makes sense.

Best practices

File during your county's appeal window, even if you are only mildly confident.
Pull three to five recent sales of homes most similar to yours in the same neighborhood.
Take time-stamped photos of any condition issues or deferred maintenance.
Use the county's own assessment ratio and base year to frame your evidence.
Bring a written summary to your hearing. Boards work through dozens of cases per day.

Common mistakes

Arguing about taxes instead of about value. The board only adjusts assessments.
Bringing Zillow or Redfin estimates instead of actual sales.
Filing late by even one day. Most counties strictly enforce the deadline.
Showing up without comparable sales evidence.
Skipping the annual appeal because 'last year wasn't worth it'.

Frequently asked questions

Can I appeal my PA property tax bill itself?

Usually no. You appeal the assessment that drives the bill. The taxing bodies set the rate; only the assessment is generally appealable.

How much can I save by appealing?

It varies. Many successful appeals reduce assessed value by 10-30%. If your county's millage is high, even a moderate reduction can save thousands a year.

Will my taxes go up if I appeal?

In Pennsylvania, the board can theoretically raise an assessment based on evidence presented. Strong comparable sales evidence reduces this risk, but it is worth understanding before you file.

Do I need an attorney to appeal?

Not usually for an annual appeal. Pro se filers often handle assessment appeals themselves. Attorneys, certified property tax appraisers, and consultants can be worth the cost for larger commercial properties or after-purchase appeals.

Can I appeal multiple years at once?

Each tax year typically requires its own annual appeal. Some counties allow special appeals after a sale or major change.
