Property Tax in Westmoreland County, 2026

A calculator and field guide for Greensburg-area homeowners — and for anyone considering a move to Westmoreland County — including Pennsylvania's millage-per-$1,000-AV system, the Common Level Ratio that bridges stale assessments to market value, the per-school-district Homestead Exclusion (Act 1), and the Property Tax/Rent Rebate program for income-qualified seniors.

Westmoreland County, home to Greensburg and 350k Pennsylvanians, operates within PA's complex multi-layered property tax system. Each county sets its own predetermined assessment ratio, the State Tax Equalization Board issues an annual Common Level Ratio (CLR) to bridge stale assessments to market value, and total tax combines three independent authorities: county + municipality + school district. School district millage typically dominates the bill — often 70%+ of the total.

How the bill is built

Pennsylvania's calculation has three steps. Step 1: Assessed Value. Each county uses its own ratio — some assess at 100% of current market value (Lancaster, Allegheny since 2012), others at lower stated ratios (Bucks at ~3% effective ratio, Philadelphia at 100%). Step 2: Common Level Ratio (CLR). The State Tax Equalization Board calculates an annual CLR to bridge stated AV to current market value. This matters most for stale-assessment counties (Bucks, Chester, Allegheny, Lehigh) where the CLR can be the basis for tax appeal valuation. Step 3: Tax. Multiply AV by the combined millage (county + municipality + school district) and divide by 1,000. For Greensburg, total millage is approximately 44.44 mills.

School district millage is the largest portion of the bill. Pennsylvania has 501 independent school districts, each setting their own millage and Homestead Exclusion. Within Westmoreland County, school district choice can change a homeowner's annual tax bill by $1,500-$5,000+ on similar-priced homes — making "what school district is this in?" the single most important question for PA relocation buyers.

Homestead Exclusion (Act 1, 2006) is state-funded. Each school district allocates its slot of the state Property Tax Reduction Allocation to homestead-qualified properties — typical reduction is $300-$700 per year. Apply once with the Westmoreland County Assessment Office (Form available March 1; deadline March 1 of the following year for that year's bill).

Property Tax/Rent Rebate (PTRR) for seniors and disabled. PA's PTRR program provides up to $1,000 base rebate for income-qualified homeowners 65+ or disabled (income limit raised to $46,520 in 2024). Residents of Philadelphia, Pittsburgh, or Scranton receive supplemental rebates of $500-$1,500. PA also exempts retirement income (including Social Security) from state income tax, which substantially boosts the effective retiree benefit. File Form PA-1000 with PA Department of Revenue.

As of April 27, 2026 · From Westmoreland County Assessment Office.

Note: Westmoreland County is the principal eastern suburb of Pittsburgh — Murrysville, Penn Township, and Hempfield Township function as commuter bedroom communities for Pittsburgh's eastern corridor. The county's economy diversified substantially after the collapse of steel/glass manufacturing (Westmoreland produced ~25% of US glass at peak in the early 20th century). Latrobe is the home of Rolling Rock beer and Arnold Palmer.

Note: Pennsylvania has no statewide assessment ratio — each county sets its own pre-determined ratio (Westmoreland uses 17.7% of 1972 base year, last reassessment 1972). This produces dramatic inconsistency between counties. Real-world effective rates depend on the millage applied to the artificial base-year-1972 AV. Combined county + municipal + school typical rate ~44 mills, producing 1.50% effective rate on current market value.

Note: PA's Property Tax/Rent Rebate Program (expanded by Act 7 of 2023, effective claims year 2024+) provides up to $1,000 rebate for homeowners 65+/widow(er) 50+/disabled with HHI ≤ $45,000 — significantly expanded from the pre-2024 $35,000 income limit. Apply with PA Department of Revenue (REV-573). Westmoreland's substantial 65+ population (24% of residents, among the oldest in PA) makes this rebate widely used.

Homestead, exemptions, and senior programs for 2026

Pennsylvania's homeowner tax relief works through three primary mechanisms: (1) the per-school-district Homestead Exclusion, (2) the income-tested Property Tax/Rent Rebate (PTRR) for seniors and disabled, and (3) the Disabled Veterans Real Estate Tax Exemption for 100% service-connected disabled veterans.

Homestead Exclusion (Act 1, 2006)

Pennsylvania's Homestead Exclusion is funded by the state's gaming revenue and allocated to school districts via the Property Tax Reduction Allocation. Each school district then applies the allocation as a reduction in assessed value for owner-occupied homes. Typical reductions in Westmoreland County range from $300-$700 per year. Apply once with the Westmoreland County Assessment Office; the application form becomes available March 1 of each year, with a March 1 deadline of the following year for that year's bill. Once granted, the exclusion auto-renews.

Property Tax/Rent Rebate (PTRR)

Pennsylvania's PTRR is one of the more generous senior property tax programs in the country. Eligible homeowners (65+ or disabled with income under $46,520) receive a base rebate of up to $1,000. Residents of Philadelphia, Pittsburgh, and Scranton receive an additional $500-$1,500 supplemental rebate. The program is funded by the Pennsylvania Lottery and is filed annually with the PA Department of Revenue (Form PA-1000). The June 30 application deadline applies to the following year's rebate.

Pennsylvania also exempts retirement income (including Social Security) from state income tax — boosting the effective retiree benefit substantially. Combined with PTRR, PA retirees can have very low total state-tax burden despite the moderate-to-high property tax rates.

Disabled Veterans Real Estate Tax Exemption

Pennsylvania veterans with a 100% service-connected disability rating qualify for full property tax exemption — but the exemption is income-tested. Income limit is approximately $108,046 in 2025 (annual cost-of-living adjustment). File Form MV-77L with the PA Department of Military and Veterans Affairs. The State Veterans Commission reviews each application; approval can take several months. Surviving spouses retain the exemption under specific conditions.

Appealing your assessment

Pennsylvania's appeal deadline is typically August 1 in most counties for the following tax year (varies — check with the Westmoreland County Assessment Office). The county Board of Assessment Appeals reviews based on comparable sales evidence, with the Common Level Ratio applied to convert market value comparisons to assessed value comparisons. PA's stale-assessment counties (Bucks last reassessed 1972, Chester 1996, Allegheny 2012) have particularly favorable appeal dynamics — recent buyers can often reduce their assessment substantially by demonstrating their purchase price is below the indicated assessed value × CLR.

Frequently asked questions

When are Westmoreland County property taxes due?

Pennsylvania has different bill cycles for the three taxing authorities. County and municipal taxes are billed in spring (typically March-April due) with discount available if paid early. School district taxes are billed in summer (typically July-September due). Each authority has its own discount/face/penalty schedule — typically a 2% discount for early payment, then face value, then 10% penalty for late payment.

Why is the school district millage so much higher than the county millage?

Pennsylvania has 501 independent school districts that fund roughly 50-60% of school operating costs through property tax (the remainder comes from state aid and federal funds). Combined with very modest county-level millage (typically 4-8 mills), the school portion ends up dominating the total bill. Within Westmoreland County, school district choice can change a homeowner's annual tax bill by $1,500-$5,000+ on similar-priced homes.

What is the Common Level Ratio (CLR)?

PA's CLR is an annual State Tax Equalization Board calculation that bridges stated assessed values to current market value. In stale-assessment counties (Bucks last reassessed 1972, Chester 1996, Allegheny 2012, Lehigh 1991), the CLR adjusts upward to compensate for the gap. The CLR matters most for tax appeals — your assessment can be challenged if it produces an effective rate higher than the county's CLR-adjusted level.

How do I qualify for PTRR (Property Tax/Rent Rebate)?

You must be 65+ or disabled, with household income under approximately $46,520 (2024). Residents of Philadelphia, Pittsburgh, or Scranton qualify for additional supplemental rebates. File Form PA-1000 with the PA Department of Revenue by June 30 for the following year's rebate. Pennsylvania also exempts retirement income from state income tax — making PA one of the more retiree-friendly states overall.
