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 government 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 of all property owners. Forms are mailed with Township real estate tax statements to all property owners each May. Changes in the status of tenants must be reported to the Tax Office every thirty days.
