Pennsylvania property tax appeals and assessments

Pennsylvania property tax, in counties under the Consolidated County Assessment Law, uses an assessment at a predetermined ratio of market value, never above 100%. In a Pennsylvania property tax appeal the board first finds your fair market value; the common level ratio is used only if the county's ratio differs from it by more than 15%. In Philadelphia, market value appeals are due to the Board of Revision of Taxes by the first Monday of October of the year before the tax year.
