Beaver County questions
When is the Beaver County assessment appeal deadline in 2027?

How do I appeal my assessment in Beaver County?
File the Notice of Intention to Appeal (2027 Tax Year) with the Beaver County Board of Assessment Appeals, Board of Assessment Appeals, Beaver County Courthouse, 810 Third Street - Assessment Office, Beaver, PA 15009-2194.
What is the common level ratio and why does it matter?
The State Tax Equalization Board publishes each county’s common level ratio: assessed value as a share of market value. The board finds your market value, then applies the county’s ratio, or the common level ratio if the two differ by more than 15%. That is how a market-value argument becomes a lower assessment.
Can my assessment go up if I appeal?
Yes. The board decides the correct value, which can be higher, and school districts and other taxing bodies can join or file appeals. Bring evidence that supports a lower value, ideally an appraisal or recent comparable sales.

Do I keep paying taxes during the appeal?
Yes. Taxes stay due on the appealed assessment. If the value is lowered, the overpayment is refunded with interest (53 Pa.C.S. §8854(c)). A pending appeal also carries over to later years until it is decided.
