Real Estate Taxes & 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 and can be found on Allegheny County's website here. 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 30. 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 owners are responsible to see that their property is properly assessed and taxed, and to request the appropriate tax bills if they have not received them by mail. No extensions or appeals will be granted due to a taxpayer not receiving a real estate tax bill.

Property Assessments

All properties in the Township are assessed by the Allegheny County Department of Real Estate and assigned a Full Market Value. The assessed values of all Township properties are available for review in the Township Tax Office or at Allegheny County's Real Estate website.

Taxpayers may calculate property tax in the following manner:

  • Multiply the home's Total Market Value by the millage rate
  • Divide the result by 1,000

Allegheny Senior Citizen Tax Relief (Act 77)

The Allegheny County Treasurer administers a program which entitles qualified senior citizen homeowners to a discount on the County and Township real estate tax amounts due on a primary residence. The County discount is 30 percent and the Township discount is 10 percent. The County Treasurer's Office determines a property owner's eligibility through an application process. More details about the process and program can be found by click this link to the Allegheny County Act 77 - Senior Citizen Tax Relief Program.
