How Assessment Works in Pennsylvania
Pennsylvania's assessment system varies dramatically by county. Some counties haven't reassessed in decades, using assessment ratios far below market value. The State Tax Equalization Board publishes a common level ratio (CLR) for each county to equalize values for appeal purposes.
Risk of Increase
In Pennsylvania, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ
Pennsylvania Property Tax Appeal Questions
What is the common level ratio (CLR) in Pennsylvania?
The CLR is published by the State Tax Equalization Board and represents the ratio of assessed values to market values in your county. When appealing, you multiply comparable sales prices by the CLR to determine the appropriate assessed value.
Can my Pennsylvania assessment increase on appeal?
Yes. The Board of Assessment Appeals or Court of Common Pleas can increase your assessment. However, recent court decisions have made it more difficult for taxing bodies to selectively target individual properties for increases.
Why hasn't my county reassessed recently?
Many Pennsylvania counties haven't conducted a county-wide reassessment in 10, 20, or even 40+ years because reassessment is politically unpopular and expensive. This creates wide disparities in assessment accuracy, which strengthens your appeal if you can show your property is assessed higher than comparable properties.
What is the effective property tax rate in Pennsylvania?
Pennsylvania property tax rates vary by county, municipality, and school district, but the effective rate (annual tax paid divided by market value) typically ranges from about 0.5% to 2.5%. Because Pennsylvania assesses property at Varies by county of market value, your actual tax bill depends on both the assessed value and the local millage or mill levy applied on top of it. If your assessed value is higher than comparable sales support, filing a appeal is one of the only ways to reduce your effective rate without waiting for a reassessment.
How long does a property tax appeal take in Pennsylvania?
Most Pennsylvania appeals take between 6 weeks and 6 months from filing to final decision. After you file County form, the assessor or review board schedules a hearing — typically within 30 to 90 days — and issues a written decision shortly after. Cases that settle informally resolve faster, while cases that advance to a formal hearing or court appeal can take several additional months. ProtestMax prepares your full evidence packet in minutes so you can file immediately and start the clock.
Can I appeal my property taxes every year in Pennsylvania?
Yes. In Pennsylvania, homeowners generally have the right to appeal their property tax assessment every year, as long as you file by the August-October 2026 (varies by county) deadline. Even if you won a reduction last year, your assessor can revalue your property the following year, and you retain the right to challenge the new value. Annual appeals are especially important during years when market values are flat or falling but assessments keep rising.
What evidence is most persuasive in Pennsylvania hearings?
The strongest evidence in a Pennsylvania appeal hearing is recent comparable sales — homes similar to yours in size, age, condition, and location that sold for less than your assessed value within the last 6 to 12 months. Equity comparisons (similar homes assessed for less than yours) are also highly persuasive. Photos of deferred maintenance, structural issues, or negative location factors (busy roads, flood zones, power lines) strengthen your case further. ProtestMax assembles all of this evidence into a hearing-ready packet tailored to Pennsylvania's rules.
