Allegheny County Property Tax Calculator
The Allegheny County Office of Property Assessments values property across the Pittsburgh area, and that assessed value is then taxed by overlapping county, municipal, and school district millage rates. Because Pennsylvania counties reassess infrequently, an owner's assessed value can sit well behind current market conditions until the next countywide reassessment.

- Homestead-type relief is available in some Allegheny County municipalities and school districts, reducing the taxable value of a primary residence.

Frequently asked questions
How is property tax calculated in Allegheny County?
The Office of Property Assessments fixes an assessed value, and county, municipal, and school district millage rates are each billed against that figure separately, combining into your total statement. Because full countywide reassessment happens infrequently, the assessed value you're taxed on may not reflect current market conditions.
How do I appeal my Allegheny County assessment?
A formal case goes to the county Board of Property Assessment Appeals and Review before the annual deadline, backed by comparable sales or similar records showing the figure is out of line.
Does Allegheny County offer a homestead exemption?
Some Allegheny municipalities and school districts run their own homestead-type exclusion that cuts a primary residence's taxable figure — whether it's available, and how much it's worth, depends on your specific local taxing bodies rather than one countywide program.
Why does my Allegheny County assessment seem out of date?
Pennsylvania counties, including Allegheny, don't reassess every property on a fixed short cycle, so your assessed value can lag well behind what the home would actually sell for today until the next countywide reassessment catches it up.
