How to Appeal Property Taxes in Pennsylvania: County Board Guide
TL;DR
Pennsylvania property tax appeals go through your county's Board of Assessment Appeals. Filing deadlines vary by county, but most fall between August 1 and October 1. PA assessment ratios and reassessment schedules differ by county, so check your county's specific rules. Appeals are free to file and you can represent yourself.
Pennsylvania's property tax system is one of the most decentralized in the country. There's no statewide reassessment schedule, no uniform assessment ratio, and no single set of deadlines. Each of the state's 67 counties runs its own show. That makes appealing more confusing than in most states, but the fundamentals are the same everywhere: if your assessed value is too high relative to market value, you have the right to challenge it.
The average effective property tax rate in Pennsylvania is around 1.53%, but it ranges from under 0.90% in some rural counties to over 2.5% in parts of the Philadelphia suburbs. School district taxes make up the largest portion of most PA tax bills.
How Pennsylvania Assessments Work
Pennsylvania counties use a "common level ratio" (CLR) system. Each county sets assessments at some fraction of market value. The State Tax Equalization Board (STEB) publishes the CLR for each county annually. This ratio represents the relationship between assessed values and actual sale prices.
For example, if a county's CLR is 85% and your property's market value is $300,000, the expected assessed value would be $255,000. If your assessment is significantly higher than what the CLR would produce, you have grounds to appeal.
The Reassessment Problem
Many Pennsylvania counties have not done a full reassessment in decades. Allegheny County last reassessed in 2012. Some rural counties are using values from the 1970s or 1980s. This creates massive inequities, as properties in rapidly appreciating neighborhoods may be under-assessed while others are over-assessed.
County-by-County Deadlines
Because each county sets its own appeal period, you must check with your county. Here are some major counties:
| County | Appeal Deadline | Effective Tax Rate |
|---|---|---|
| Philadelphia | October 7, 2026 (first Monday) | 1.36% |
| Allegheny (Pittsburgh) | March 31, 2026 | 2.15% |
| Montgomery | September 1, 2026 | 1.62% |
| Bucks | August 1, 2026 | 1.52% |
| Delaware | September 1, 2026 | 2.10% |
| Chester | September 1, 2026 | 1.55% |
| Lancaster | September 1, 2026 | 1.65% |
| Berks | September 1, 2026 | 1.70% |
Always confirm your county's specific deadline with the Board of Assessment Appeals office. Deadlines shift year to year.
Step-by-Step: Pennsylvania Property Tax Appeal
Step 1: Get Your Assessment Information
Find your property's assessed value on your county's assessment website. Note the assessed value, the property classification, and the physical characteristics on file (square footage, lot size, bedrooms, bathrooms). Errors in the property record are common.
Step 2: Calculate Your Expected Value Using the CLR
Look up your county's Common Level Ratio on the STEB website. Multiply your home's estimated market value by the CLR. If the result is significantly lower than your assessed value, you have a case.
Example: Your home's market value is $280,000. Your county's CLR is 72%. Expected assessed value = $280,000 x 0.72 = $201,600. If your assessed value is $240,000, you're over-assessed by nearly $40,000.
Step 3: Gather Evidence
Comparable sales are your strongest tool. Find 3-5 similar homes that sold recently in your area. Adjust for differences in size, condition, and features. Photos of property condition issues help too. See our comparable sales guide for detailed instructions.
Step 4: File Your Appeal
Submit the appeal form to your county's Board of Assessment Appeals. Most counties have downloadable forms on their website. Include your name, property address, parcel number, current assessed value, and requested value. There is typically no filing fee.
Step 5: Attend the Hearing
The Board of Assessment Appeals will schedule a hearing, usually within 2-6 months. Present your comparable sales, CLR calculation, and any property condition evidence. Hearings are informal and typically last 15-20 minutes. You can bring a tax consultant or attorney, but it's not required.
Step 6: Appeal the Decision
If the Board rules against you, you can appeal to the Court of Common Pleas within 30 days. This is a more formal legal proceeding where an attorney is recommended.
Pennsylvania Property Tax Exemptions
Homestead Exclusion
Pennsylvania's homestead exclusion is set at the local level. Each school district can authorize a homestead exclusion of up to 50% of the median assessed value of homesteads in the district. Not all districts have adopted it. Check with your school district.
Property Tax/Rent Rebate Program
Pennsylvania offers property tax rebates for seniors (65+), widows and widowers (50+), and people with disabilities (18+). Income limits apply (currently $45,000 for homeowners, including half of Social Security income). Maximum rebate is $1,000, though supplemental rebates can increase this in some cases.
Disabled Veterans Exemption
Veterans with 100% service-connected disability are exempt from all property taxes on their primary residence. The exemption must be applied for through the county Board of Assessment.
Effective Tax Rates by Region
PA property taxes vary enormously by location:
| Region | Effective Rate Range | Key Driver |
|---|---|---|
| Philadelphia suburbs (Delco, Montco, Bucks, Chester) | 1.40% - 2.50% | High school district levies |
| Pittsburgh metro (Allegheny, Westmoreland) | 1.80% - 2.40% | Multiple taxing bodies |
| Lehigh Valley (Lehigh, Northampton) | 1.50% - 2.00% | School taxes |
| Rural central PA | 0.90% - 1.40% | Lower land values |
| Poconos (Monroe, Pike) | 1.60% - 2.20% | School and county levies |
Tips for PA Property Tax Appeals
- Use the CLR: The Common Level Ratio is your most powerful tool. If your assessment exceeds what the CLR suggests, the math is on your side.
- Check for data errors: Many PA counties use very old property records. Verify square footage, lot size, and building details.
- School taxes are the biggest piece: Even if you can't change the assessment, check that you're getting all available school tax exemptions.
- Don't wait for a reassessment: Some counties haven't reassessed in 20+ years. You can still appeal using the CLR methodology.
- Consider a professional for high-value properties: For homes assessed above $500,000, the potential savings justify hiring a consultant. See our consultant vs. DIY comparison.
Frequently Asked Questions
Why are Pennsylvania property taxes so complicated?
Because there's no state-level uniformity. Each of 67 counties sets its own assessment ratio, reassessment schedule, and appeal deadlines. Add in separate tax levies from counties, municipalities, and school districts, and you get a system that's hard to navigate but also full of appeal opportunities.
How much can I save by appealing?
The average successful appeal in Pennsylvania reduces the assessed value by 10-20%. On a home with a $6,000 annual tax bill, that translates to $600-$1,200 per year in savings. For advice on building a strong case, see our evidence guide.
Can the school district appeal my assessment?
Yes. In Pennsylvania, school districts and municipalities can file appeals to increase your assessment. This sometimes happens after a property sale reveals the assessed value is much lower than the purchase price. It's one reason to be strategic about when and how you appeal.
Is the Property Tax/Rent Rebate the same as a homestead exemption?
No. The rebate program is a state-funded cash rebate based on income. The homestead exclusion is a local reduction in assessed value. You can qualify for both if you meet the requirements.
