Philadelphia's 2027 Property Tax Appeals: Everything You Need to Know

Philadelphia Property Tax Appeal 2027: Key Deadlines, Process, and How to Reduce Your Property Assessment

Philadelphia property owners heading into the 2027 tax year should review their property assessments carefully. The City of Philadelphia’s Office of Property Assessment (OPA) updates valuations annually, and changes in market conditions can result in higher assessed values and increased real estate taxes.

An increase in your property assessment does not necessarily mean the value is accurate. Property owners have the right to challenge their property assessment through the City’s formal appeal process.

Understanding the timeline is essential. Missing a deadline can eliminate your ability to challenge your property assessment for the entire tax year.

Working With Counsel on a Philadelphia Property Tax Appeal

Property tax assessment appeals can be document-intensive and time-sensitive. Many property owners choose to work with professionals, such as attorneys or appraisers, to help evaluate whether an appeal is warranted and to prepare supporting materials.

While some tax assessment appeals can result in tax savings, outcomes vary depending on the property, supporting evidence, and market data presented during the process.

How Do I Start a Philadelphia Property Tax Assessment Appeal?

To begin the tax assessment appeal process, it is essential to gather all necessary documentation. If you have received an assessment notice from the OPA, retain all forms and correspondence. If you have not received the appropriate appeal forms, Nochumson P.C. can assist you in obtaining and completing them.

If this occurs, your tax obligation could increase. It is critical to weigh the potential risks and benefits before proceeding. Our attorneys can help you evaluate your specific situation and determine whether filing an appeal is in your best interest.

3. Understand Property-Type Differences

Understanding these distinctions is essential to building a strong appeal. Our team ensures that your filing reflects the nuances of your property type and is positioned for success.

4. Plan Ahead and Meet Deadlines

Regardless of when you receive your assessment notice, all tax assessment appeals are due on the same deadline. For the 2027 tax year, property assessment appeals are typically due by the first Monday in October.

Missing this deadline means your new assessment will go into effect for the following tax year without the opportunity for adjustment.

Early preparation is key to submitting a complete and compelling appeal on time.
