Millage Rates
The millage rate is a financial tool used by municipalities to calculate property taxes. In 2025, Allegheny County Executive Sara Innamorato and County Council came to a joint agreement to increase the millage rate to 6.43.
This means that a property's tax will be $6.43 per $1,000 of its valuation.
Property Assessment Tax Calculator Millage Rates
Different entities such as municipalities and school boards set their own mill rates. While the Treasurer's Office provides information about the millage rates for local municipalities and school districts, the office ONLY COLLECTS Allegheny County Real Estate Taxes. Please contact your local municipality and/or school district for questions about any other taxes.
Gross (Face) Tax
Allegheny County provides residents with a 2% discount on their real estate taxes if their current-year tax payment is submitted by March 31. Gross, also known as Face, Tax is the base tax amount due, as determined by the Allegheny County Office of Property Assessment.
Delinquent Taxes
The Treasurer's Office only collects real estate taxes for the current tax year. Unpaid past due taxes become delinquent and are turned over to Jordan Tax Service on January 1 of each year. Unpaid taxes accrue a one-time penalty of 5% after the gross tax due date, and accrue 1% interest on the gross tax per each month the tax remains unpaid.
For delinquent and liened tax years contact Jordan Tax Service at 412-835-5243.
NOTE: Continued failure to pay taxes may lead to a Sheriff Sale of your property.
