How to Appeal Your Property Tax in Pennsylvania: Step-by-Step Guide
If your Pennsylvania property tax assessment seems too high, you have the legal right to challenge it — and many homeowners who do end up saving hundreds or thousands of dollars per year. Pennsylvania’s outdated assessment system, where some counties haven’t done a county-wide reassessment in 20–50 years, creates frequent situations where individual properties are assessed above their actual market value. The appeal process goes through your county’s Board of Assessment Appeals, and if you prepare solid evidence, you have a reasonable chance of winning a reduction.
This guide walks through the Pennsylvania property tax appeal process step by step, from determining whether you have a valid case to presenting evidence at a hearing.
Step 1: Determine If You Have Grounds for Appeal
Before investing time in an appeal, check whether your assessment is actually too high. Here’s how to evaluate:
| What to Check | Where to Find It | What It Tells You |
|---|---|---|
| Your Assessed Value | County assessment office website or tax bill | The value the county uses to calculate your tax |
| Common Level Ratio (CLR) | PA State Tax Equalization Board website | Ratio to convert assessed value to estimated market value |
| Your Estimated Market Value | Assessed Value / CLR | What the county thinks your home is worth at market |
| Actual Market Value | Recent comparable sales, Zillow/Redfin, appraisal | What your home would actually sell for today |
The key calculation: Multiply your assessed value by your county’s CLR. If the result is significantly higher than your home’s actual market value (based on recent comparable sales), you likely have grounds for appeal.
Example: Your home’s assessed value is $180,000. Your county’s CLR is 0.70 (70%). That means the county estimates your market value at $180,000 / 0.70 = $257,143. If comparable homes in your neighborhood are selling for $220,000, your assessment is arguably $37,000 too high — a strong case for appeal.
Most successful appeals involve at least a 10–15% discrepancy between the assessed market value and actual market value. Smaller gaps may not justify the time investment. Estimate how much you’d save with our estimate your property taxes.
Step 2: Gather Your Evidence
The strongest evidence for a property tax appeal comes from recent comparable sales. You need to prove that the county’s implied market value for your property exceeds what similar properties actually sell for.
Comparable Sales (Most Important)
- Find 3–5 homes that sold within the past 12 months within 0.5–1 mile of your property
- Comparables should be similar in size (within 20% of square footage), age (within 10–15 years), style (colonial to colonial, rowhome to rowhome), and condition
- Get sale prices from county deed records, Zillow, Redfin, or your real estate agent
- If comparable sales are lower than your implied market value, your case is strong
Property Condition Issues
- Document any condition problems that reduce your home’s value below the county’s estimate: structural issues, outdated systems, needed repairs, flood zone designation
- Photos, contractor estimates, and inspection reports all serve as evidence
- The county’s property card may contain errors — wrong square footage, incorrect number of bathrooms, finished basement listed when it’s unfinished. These factual errors are the easiest appeals to win
Recent Appraisal
- A professional appraisal ($350–$500) carries significant weight with appeal boards
- If you purchased the home recently and the sale price was below the assessed value, the purchase price itself is strong evidence
- The cost of an appraisal is usually worth it if the potential tax savings exceed $500/year
Step 3: File the Appeal
Pennsylvania property tax appeals are filed with your county’s Board of Assessment Appeals. Each county has its own procedures, but the general process:
- Obtain the appeal form from your county assessment office or website. Most counties have a simple one-page form.
- Meet the filing deadline. This is critical — deadlines vary by county but are typically in early to mid-year. Many counties set the deadline between March and September. Check your specific county’s deadline immediately; missing it means waiting until next year.
- Pay the filing fee. Most counties charge $25–$75 to file an appeal. Some counties waive the fee for senior citizens.
- Submit your evidence with the appeal form or prepare to present it at the hearing. Some counties allow you to submit documentation in advance; others only accept it at the hearing.
| County | Typical Filing Deadline | Filing Fee | Hearing Format |
|---|---|---|---|
| Philadelphia | October 1 (first Monday) | No fee | Board of Revision of Taxes |
| Allegheny (Pittsburgh) | March 31 | $50 | Board of Property Assessment |
| Montgomery | September 1 | $35 | Board of Assessment Appeals |
| Delaware | September 1 | $25 | Board of Assessment Appeals |
| Chester | September 1 | $35 | Board of Assessment Appeals |
| Lancaster | September 1 | $25 | Board of Assessment Appeals |
| Lehigh | September 1 | $25 | Board of Assessment Appeals |
Step 4: Attend the Hearing
Most county appeal hearings are informal and last 15–30 minutes. You don’t need a lawyer, though hiring one ($500–$2,000 for a residential appeal) can be worthwhile for higher-value properties where the tax savings justify the cost. Here’s what to expect:

- Present your case. Explain why you believe the assessment is too high, referencing your comparable sales, property condition issues, or factual errors in the property record.
- Show your evidence. Bring printed copies of comparable sales data, photos of property condition issues, and any supporting documents. Organize them clearly — the board sees dozens of cases per day.
- Answer questions. Board members may ask about your property’s features, renovations, or why you chose specific comparables.
- The board decides. Some boards issue decisions immediately; others mail written decisions within 30–60 days.
Tips for the hearing:
- Be concise and factual — emotional arguments don’t work
- Focus on comparable sales, not your ability to pay
- If the county’s property record has factual errors (wrong square footage, etc.), lead with those — they’re the easiest to win
- Bring extra copies of everything for the board members
- Dress professionally — it signals you take the process seriously
Step 5: If You Lose — Next Steps
If the Board of Assessment Appeals denies your appeal or doesn’t reduce the assessment enough, you have further options:
- Appeal to the Court of Common Pleas. You typically have 30 days after the board’s decision to file a statutory appeal with your county’s Court of Common Pleas. This is a more formal legal proceeding, and hiring an attorney is strongly recommended.
- Negotiate an informal settlement. After filing a Common Pleas appeal, the county solicitor’s office may offer a settlement to avoid litigation. Many cases are resolved through negotiated settlements at this stage.
- Full trial. If settlement isn’t reached, the case goes to trial before a judge. This is expensive ($3,000–$10,000+ in legal fees) and usually only makes sense for high-value properties or commercial real estate.
What You Can Expect to Save
| Assessment Reduction | Approximate Annual Tax Savings (at 2.0% effective rate) | 10-Year Savings |
|---|---|---|
| $20,000 | $400 | $4,000 |
| $40,000 | $800 | $8,000 |
| $60,000 | $1,200 | $12,000 |
| $80,000 | $1,600 | $16,000 |
| $100,000 | $2,000 | $20,000 |
A successful appeal that reduces your assessed value by $50,000 in a county with a 2.0% effective rate saves roughly $1,000 per year — every year until the next reassessment. Over 10 years, that’s $10,000 in savings from a process that costs $25–$75 in filing fees and a few hours of preparation. The math strongly favors filing if your evidence supports a reduction.

Frequently Asked Questions
When can I appeal my property tax assessment in Pennsylvania?
Filing deadlines vary by county — most fall between March and September. Some counties (like Philadelphia) have October deadlines. Check your county assessment office for the exact deadline. You can typically appeal any year, not just during a reassessment period. Missing the deadline means waiting until the following year’s filing window.
How much does it cost to appeal property taxes in PA?
Filing fees range from $0 (Philadelphia) to $75 depending on the county. If you handle the appeal yourself, total out-of-pocket is just the filing fee. Hiring an attorney for a residential appeal costs $500–$2,000. Getting a professional appraisal to support your case costs $350–$500. For potential annual savings of $500–$2,000+, the investment typically pays back within 1–2 years.
Do I need a lawyer to appeal property taxes in Pennsylvania?
Not for the initial Board of Assessment Appeals hearing. Most homeowners present their own cases successfully. If your appeal is denied and you want to escalate to the Court of Common Pleas, hiring an attorney is strongly recommended — the legal process is more formal and the county will be represented by a solicitor. For high-value properties or complex situations, an attorney adds value at any stage.
Can the county raise my assessment if I appeal?
Theoretically yes — the board could determine that your assessment is actually too low and increase it. In practice, this is extremely rare. County boards generally either reduce the assessment, leave it unchanged, or occasionally offer a smaller reduction than requested. The risk of an increase is minimal and shouldn’t deter you from filing if your evidence supports a lower value.
What is the Common Level Ratio (CLR)?
The CLR is a ratio published by the State Tax Equalization Board that converts county assessed values to estimated market values. If your county’s CLR is 0.65, it means assessed values are roughly 65% of market value on average. You use the CLR to determine whether your specific property’s assessed value (converted to market value) is higher than your home’s actual market worth. If Assessed Value / CLR exceeds your home’s true market value, you have grounds for appeal.
How long does a property tax appeal take in Pennsylvania?
The Board of Assessment Appeals process typically takes 2–4 months from filing to decision. Some counties are faster (4–6 weeks), while others with heavy caseloads (Philadelphia, Allegheny County) may take longer. If you escalate to the Court of Common Pleas, add another 6–12 months. Most residential appeals are resolved at the board level without needing further escalation. Use our tax calculator to estimate your savings from a successful appeal.
