Pennsylvania assesses at market value (Allegheny) or a fraction of it via the county's Common Level Ratio (CLR). If the County's number is higher than what your property would actually sell for, you're over-assessed — and likely over-paying. Beaver County (PA 3rd–8th class) sets its annual assessment-appeal deadline under 53 Pa.C.S. §8844; the statutory default for 3rd–8th class counties is August 1. PA assesses at a fraction of market value via the county's Common Level Ratio (CLR) — apply the CLR to test whether your assessment over-states market value.
Honest null: Beaver County's live assessment roll isn't onboarded yet, so we can't run the per-parcel over-assessment check here. Use your county's assessor portal + the Common Level Ratio (CLR) to test your own parcel, or see the live Allegheny example.
1. Confirm your assessed value on the Beaver County assessor portal. 2. Find your market value (recent sale, or assessed ÷ CLR). 3. If over-stated, file an appeal with the Beaver County county Board of Assessment Appeals on or before August 1 2026. 4. Present comps at the hearing.
Most owners who win use a contingency property-tax appeal firm — it costs nothing unless they cut your bill, then takes a share of the first-year saving. We connect Beaver owners with vetted contingency firms.
