Rate Breakdown

Property taxes in Allegheny County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Allegheny County

Property taxes in Allegheny County are determined by two primary factors: the assessed value of your property and the combined millage rates of your local taxing bodies. The assessed value is calculated by the Allegheny County Office of Property Assessments (OPA) based on the property’s base-year market value, which is currently set to 2012 levels. To calculate your annual tax burden, the county applies a millage rate—a tax rate expressed as dollars per $1,000 of assessed value—across three entities: the county, your municipality, and your local school district.

Because these three entities set their own millage rates independently, your total tax bill reflects the sum of these individual requirements. It is important to note that when a property is sold, the assessment may be subject to a "spot appeal" by the school district or municipality, which can lead to a reassessment of the property’s value to reflect the current sale price.

Available Exemptions

Pennsylvania offers several programs to help property owners reduce their tax liability. Eligibility requirements are strictly enforced, and many require annual renewal:

• Homestead/Farmstead Exclusion: This reduces the assessed value of your primary residence, lowering the school district portion of your tax bill.
• Senior Citizen Tax Relief: The state-run Property Tax/Rent Rebate Program provides rebates to eligible seniors (65+), widows/widowers (50+), and individuals with disabilities (18+).
• Disabled Veterans Real Property Tax Exemption: Honorably discharged veterans who are 100% permanently disabled due to service-connected injuries may be eligible for a full exemption from real estate taxes.
• Longtime Owner Occupant Program (LOOP): Designed to assist residents in areas experiencing rapid property value appreciation, this program provides tax relief for those who have lived in their homes for a specified period.

Payment Schedule & Deadlines

In Allegheny County, tax bills are typically issued in early spring. While specific dates vary by municipality, the standard cycle generally follows these parameters:

• Discount Period: Most jurisdictions offer a 2% discount if the full tax amount is paid within the first two months of the billing cycle.
• Face Period: Taxes paid at the base amount are due by the end of the second month.
• Penalty Period: Payments made after the face period deadline are subject to a 10% penalty.

Failure to pay property taxes by the end of the calendar year may result in the filing of a tax lien against the property, which can lead to legal action or the eventual sale of the property at a sheriff's sale.

Appealing Your Assessment

If you believe your property’s assessed value does not accurately reflect its market value, you have the right to file an appeal with the Allegheny County Board of Property Assessment Appeals and Review (BPAAR). Appeals must generally be filed by March 31st of the current tax year. You will need to provide evidence, such as recent appraisals or comparable sales data, to support your claim. It is highly recommended to consult with a professional appraiser or real estate attorney to ensure your appeal is properly documented and presented.
