Appeal Your Property Assessment With the Berks County Assessment Office
The Berks County Assessment Office takes appeals from property owners who believe their property assessment is wrong, and it posts the forms needed to file one. The office maintains ownership and assessment records for parcels within Berks County and works with property owners, municipalities, tax collectors and school districts concerning assessments. It does not issue tax bills or collect taxes, so for current taxes you contact the appropriate Tax Collector and for delinquent taxes you contact Tax Claim.
Two appeal forms are posted on the Assessment Office forms page, both marked Updated 03/19/2026: an Appeal Form and an Annual Appeal Form. A form is required to appeal a property assessment. The open appeal period to file an Annual Appeal is June 15 to August 1 each year. No filing period is printed for the other Appeal Form, so ask the office which form fits your situation and when it may be filed.
There is a filing fee. The appeal and the filing fee must be received on or before the filing deadline. The page points to New Filing Fees for Assessment Appeals effective January 1, 2026 for more information about the fees but does not print the amounts, so ask the office what you will owe.
The appeal form is a two-page document, and it is important to read and complete both pages. Keep the information on the form clear and legible. All supporting documentation should be submitted with the appeal form so the Board can make an informed decision at the time of the hearing. You must provide one copy of all evidence submitted, to be retained in the appeal file, and a picture of the subject property. Common Level Ratio (CLR) information, which is used when filing for an appeal, is on the county's Common Level Ratio (CLR) page.
To file:
- Print and complete both pages of the form. The forms page advises using Internet Explorer to complete a form online and print it; otherwise, simply print the form.
- Attach your evidence and a picture of the property.
- File the appeal and any attachments by mail or in person, with the filing fee.
Appeal forms may not be sent via e-mail or fax. The forms page refers to filing "at the above address" without printing it, so confirm with the office where to mail or drop off your appeal before you file.
The Assessment Office is at County of Berks South Campus, 400 E. Wyomissing Avenue, Mohnton, PA 19540, open Monday through Friday 8:00 am to 5:00 pm. The office has installed a drop box for customer convenience. Its general-questions number is 610-478-6262 and its general email address is assessment@berkspa.gov.
All appeals will be conducted in person, and instructions will be on your hearing notice. If you have an expert witness or counsel, it is necessary for them to be with you at the time of your hearing.
