Philadelphia property owners: the deadline to appeal your 2026 property tax assessment is Monday, October 6, 2025—just a few weeks away.
Here’s what to keep in mind:
1. When an appeal may be worthwhile
- If your property is clearly over-assessed, you may have a good case.
- Appeals can also be based on non-uniformity (your home is assessed higher than comparable neighbors) or incorrect property details (square footage, number of bathrooms, etc.).
- The bigger the discrepancy, the stronger your chances.
2. When an appeal may not be the right move
- If your property is still undervalued, appealing could backfire.
- Remember: a tax assessment increasing doesn’t always mean it’s unfair—it depends on whether the new value matches market reality.
3. How to appeal
- Check your 2026 assessment online through Philadelphia’s Property Search.
- File your appeal with the Board of Revision of Taxes before October 6.
- Expect the process (and final decision) to take time.
4. Options for moving forward
- Hire an attorney who specializes in Philadelphia tax appeals.
- Work with an appraiser familiar with the process.
- Use a tax appeal service (such as InCenter), which offers contingency-based reviews and representation. For many owners, this can be the simplest path.
