How the Common Level Ratio (CLR) Works

Every county in Pennsylvania has a state-mandated Common Level Ratio (CLR). It represents the ratio of assessed value to actual market value county-wide.

For tax year 2027 appeals in Allegheny County, the ratio is locked at 49.30%. This means if your home's current fair market value is $200,000, your assessment should be $98,600. If your current county assessment is higher, you are being over-assessed.

If your county assessment reads $140,000 but the math indicates $98,600, a BPAAR appeal could reduce your assessment by $41,400, lowering your annual school, municipal, and county tax bills.
