Best Pennsylvania Property Tax Appeal Services in 2026 (Compared)

Last updated: June 26, 2026

Pennsylvania property tax appeals are filed with the county Board of Assessment Appeals (or equivalent body). Deadlines vary by county but most fall between September and October. Pennsylvania uses a base-year assessment system in some counties, meaning assessments may not reflect current market value until a county-wide reassessment occurs. Philadelphia and Allegheny County have among the most active appeal markets in the state. On a $400,000 home at a 1.5% effective rate, a 10% reduction saves $600 per year.
