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.

How do property tax appeals work in Pennsylvania?
What is the common level ratio in a Pennsylvania appeal?
The common level ratio is the ratio of assessed value to current market value used generally in a county, as last determined by the State Tax Equalization Board. In an appeal it is used only when a county's pre-determined ratio differs from it by more than 15%, and only after the appeal board has found the fair market value.

Law scope: Pennsylvania's Consolidated County Assessment Law sets the assessment and appeal rules in every county except Philadelphia and Allegheny, which follow their own assessment laws and home rule charter rules.
