How Allegheny County property taxes are calculated - USA Today
Allegheny County homeowners can better understand their property tax bills by knowing how assessed values, millage rates and payment deadlines determine what they owe.
Property tax bills rely on several figures. The calculation begins with a property's assessed value, which is used with a millage rate to determine the tax owed.
Homeowners may see more than one millage rate because Allegheny County, municipalities and school districts can each establish their own rates. Those separate taxes contribute to a property's overall tax burden.
Payment timing can affect how much a homeowner owes.
For Allegheny County real estate taxes, taxpayers received a 2% discount for paying by March 31. The face amount was due April 30.
After that deadline, the county applies a one-time 5% penalty, then 1% interest for each month the bill remains unpaid.
Those dates apply to county real estate taxes and should not automatically be used for every property tax bill. Municipalities and school districts can have different collection schedules.
Property reassessment adds another factor for Allegheny County homeowners to watch.
The county has been using 2012 base-year property values, but a court has ordered a countywide reassessment. That process. to being in 2027, could eventually change the assessed value used to calculate an individual property's taxes.
A reassessment does not mean every homeowner's tax bill will automatically increase. The eventual effect on an individual property will depend on the values and tax rates used to calculate its bill.
When reviewing a property tax bill, homeowners should look closely at four details: the assessed value, millage rate, taxing body and payment deadline. Together, those numbers show how the amount owed was calculated and when it must be paid.
