The Office of Property Assessment (OPA) determines what every piece of property within Philadelphia is worth. The assessed dollar value is used to calculate the property’s real estate tax due. Real estate tax (also known as property tax) provides a large part of our City’s public school funding.

We also handle abatement and exemption programs that may reduce a property’s real estate tax bill. If a property owner disagrees with an assessment or believes that an abatement or exemption has not been properly applied, they can request a First Level Review of their assessment.

You can search and compare property values through the City’s online property search application.
