Real Estate Taxes and Property Assessments

Real Estate Taxes

Real Estate Taxes, referred to as property taxes, are levied on all residential, commercial, industrial, and other non-exempt real estate by three separate governmental entities:

  • Allegheny County
  • The Township of Upper St. Clair
  • The School District of Upper St. Clair
The taxes are calculated as the product of two factors; the assessed value of the property, and the millage rate.  The assessed value is 100 percent of the market value of the property.  The millage rates are set yearly by each of the three taxing jurisdictions.  A mill is 1/1000 of a dollar of total assessed property value in the Township.

Tenant Registration

Tenant registration is required by all property owners.  Registration forms must be provided to the Tax Office annually by June 30th. Changes in occupancy must be reported to the Tax Office within one month of the new or changed occupancy.

Tax Due Dates

Real Estate Taxes owed to the Township and School District are due according to the following schedule:

Tax Due To: Township School District
Bills Mailed May 1 July 1
Due - 2% discount May 1 - June 30 July 1 - Aug. 31
Due - face value July 1 - Aug. 31 Sept. 1 - Oct. 31
Due - 10% penalty after Aug. 31 after Oct. 31

Property Assessments

All properties in the Township are assessed by the Allegheny County Office of Property Assessment and assigned a Full Market Value.  Municipal governments are not permitted to realize more than a 5% increase in revenues because of increases in total assessed valuation.

The assessed values of all Township properties are available for review in the Township Tax Office or at Allegheny County's Real Estate Website.

All properties are assessed at 100% of the market value.  Taxpayers may calculate property tax in the following manner:

  • Multiply the home's Full Market Value as assigned by Allegheny County by Upper St. Clair's current Millage Rate
  • Divide the result by 1000
