Cumberland County Property Tax Appeal, Pennsylvania

Travis BunnTravis Bunn·Updated July 22, 2026

Cumberland County is located in South Central Pennsylvania with a population of approximately 277,000 as of 2025. The county seat is Carlisle, and major population centers include Hampden, Mechanicsburg, and Carlisle. Property tax appeals are particularly important here because Cumberland County's median annual property tax bill of $3,586 is significantly higher than the national median of $2,400. The county assesses property at 100% of 2010 base-year values, which can result in assessment inequities as market conditions change. With an effective tax rate of 2.06%, Cumberland County homeowners pay nearly double the national median rate of 1.02%, making accurate assessments critical for fair taxation.

On the typical Cumberland County home, valued near $174,600 at the county’s effective tax rate of 2.06%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: September 1, 2026

The deadline to file your Property Assessment Appeal Form is annually September 1. Your Appeal Form must be received in the Assessment Office by close of business (4:30 pm) on September 1, annually.

How Cumberland County Assesses Property

100%of market value

Assessed by: Cumberland County Assessment Office

Assessment cycle: base-year (2010)

Notices typically mailed: Spring (typically April)

Cumberland County assesses all real estate property at 100% of 2010-year value. Unlike many Pennsylvania counties that use lower assessment ratios, Cumberland County uses full market value from its 2010 base year. For example, if your home's current market value is $350,000 but your assessed value remains at $250,000 from the 2010 base year, you would pay approximately $5,150 annually at the county's 2.06% effective rate based on that $250,000 assessed value, not the current market value. However, if your assessed value is higher than comparable properties from the same base year, you have grounds for an appeal even though the assessment ratio is 100%.

The Appeal Process

Appeals are heard by the Board of Assessment Appeals. The Board of Assessment Appeals will schedule a hearing where you present your evidence to an independent board appointed by the County Commissioners. Hearings are typically informal, lasting 10-15 minutes, where you can present comparable sales, photos, and other documentation showing your property is over-assessed.

1

Step 1: Obtain the appropriate appeal form from the Cumberland County Assessment Office at Room 104, One Courthouse Square, or download from the county website. Select the Residential/Land Appeal Form, Agricultural Appeal Form, or Commercial Industrial Form based on your property type.

2

Step 2: Gather evidence to support your appeal, including recent comparable sales (within the past 12-18 months), photos documenting property condition, repair estimates for any defects, and your property record card from the county showing the assessment details. Research sales of similar properties in your neighborhood using the Cumberland County Property Mapper or DataScout tools.

3

Step 3: Complete the appeal form with accurate property information and your proposed assessed value. Include your reasoning and attach all supporting documentation. Pay the required appeal filing fee (check county website for current fee amount) payable to Cumberland County General Fund.

4

Step 4: File your completed appeal form, evidence, and filing fee with the Assessment Office by September 1 at 4:30 PM. Forms can be submitted in person at Room 104 or mailed to One Courthouse Square, Room 104, Carlisle, PA 17013. If filing by mail, ensure it is received by the deadline, not just postmarked.

5

Step 5: Attend your hearing before the Cumberland County Board of Assessment Appeals. You will have the opportunity to present your evidence and explain why your assessment should be reduced. The Board will review your evidence, may ask questions, and will issue a written decision after the hearing.

6

Step 6: If you disagree with the Board's decision, you can file an appeal to the Court of Common Pleas of Cumberland County within 30 days of the Board's decision.

7

Step 7: As a final option, if the Court of Common Pleas decision is unfavorable, you may appeal to the Pennsylvania Commonwealth Court, though this level typically requires legal representation.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Cumberland County for 2026?
The deadline to file your property tax assessment appeal in Cumberland County is September 1, 2026, by 4:30 PM. Your appeal form must be received at the Assessment Office by this deadline, not just postmarked. This is an annual fixed deadline that applies each year. However, if you receive a Change of Assessment Notice at any time during the year, you have 40 days from the mailing date of that notice to file an appeal, regardless of the annual September 1 deadline. Missing the deadline means you'll have to wait until the following year to appeal and will continue paying taxes based on your current assessment.
How do I file a property tax appeal in Cumberland County?
To file a property tax appeal in Cumberland County, you must obtain and complete the appropriate appeal form from the Assessment Office at One Courthouse Square, Room 104, in Carlisle. Select either the Residential/Land Appeal Form, Agricultural Appeal Form, or Commercial Industrial Form depending on your property type. Complete the form with your property information and proposed assessed value, attach supporting evidence such as comparable sales and photos, and include the required filing fee payable to Cumberland County General Fund. You can file in person at Room 104 between 8:00 AM and 4:30 PM Monday-Friday, or mail it to One Courthouse Square, Room 104, Carlisle, PA 17013, ensuring it's received by the September 1 deadline.
What evidence do I need for a successful property tax appeal in Cumberland County?
For a successful appeal in Cumberland County, you need strong comparable sales evidence showing similar properties in your neighborhood that sold for less than your assessed value within the past 12-18 months. Include at least 3-5 comparable sales with similar square footage, age, condition, and location. Photos documenting any property defects, damage, or poor condition are essential. Repair estimates from licensed contractors for needed work strengthen your case. You should also obtain your property record card from the Assessment Office to verify the county has accurate information about your property's characteristics. A professional appraisal can be helpful but is not required. The Board wants objective market data, not opinions about property values.
What is the homestead exemption worth in Cumberland County?
Cumberland County participates in Pennsylvania's Homestead/Farmstead Exclusion program (Act 50), which provides school property tax reductions for owner-occupied primary residences. The benefit amount varies by school district in Cumberland County, typically ranging from $100 to $300 in annual school tax savings, depending on which school district your property is located in and how much gaming revenue funding is allocated. To receive this benefit, you must apply by March 1st with the Assessment Office at (717) 240-6350. Once approved, the exclusion remains valid until you change residence or sell the property, so you don't need to reapply annually. Contact the Assessment Office for your specific school district's current exclusion amount.
How does Cumberland County's 100% assessment ratio affect my property taxes?
Cumberland County assesses all real estate at 100% of 2010 base-year values, which means your assessed value should theoretically equal your property's market value as of 2010. However, because the county hasn't conducted a countywide reassessment since 2010, your current assessed value may not reflect today's market conditions. This creates appeal opportunities because if similar properties in your area have lower 2010 base-year assessments, you may be over-assessed relative to those comparable properties even though both use the 100% ratio. When appealing, you'll use comparable sales and the Pennsylvania State Tax Equalization Board's Common Level Ratio to demonstrate that your assessment is too high compared to similarly situated properties from the same 2010 base year.
What happens after I file my appeal with Cumberland County?
After you file your appeal with the Cumberland County Assessment Office by September 1, the Board of Assessment Appeals will schedule a hearing, typically held in the fall (before October 31). You'll receive written notice of your hearing date, time, and location. At the hearing, you'll have approximately 10-15 minutes to present your evidence to the Board, which is an independent board appointed by the County Commissioners to hear assessment appeals. You should bring multiple copies of your evidence including comparable sales data, photos, and any other supporting documentation. The Board will review your evidence, may ask questions, and will issue a written decision typically within a few weeks. If you disagree with the Board's decision, you have 30 days to appeal to the Court of Common Pleas of Cumberland County.
Can I appeal if I just bought my property in Cumberland County?
Yes, you can appeal your property assessment in Cumberland County even if you recently purchased the property, but your purchase price can actually work against you in an appeal. If you paid market value in a recent arm's-length transaction, the Assessment Office and Board may argue that your purchase price proves the current assessment is accurate or even too low. However, you can still appeal if you believe comparable properties have lower assessments, if there were special circumstances affecting your purchase price, or if you have evidence of property defects discovered after purchase that reduced the value. The key is demonstrating assessment inequity compared to similar properties using the 2010 base-year valuations, not just arguing that your current assessment is too high. Recent buyers sometimes have valid appeals based on uniformity issues with neighboring properties.
Are disabled veterans exempt from property taxes in Cumberland County?
Yes, honorably discharged veterans with a 100% permanent and total service-connected disability rating from the VA may qualify for complete exemption from all real estate taxes in Cumberland County, including county, municipal, and school district taxes. To qualify, you must have served during wartime or received an Armed Forces Expeditionary Medal, demonstrate financial need (gross annual income of $114,637 or less), and the property must be your primary residence. Unremarried surviving spouses of eligible veterans can also receive this exemption. The exemption is valid for 5 years and can be renewed. To apply, contact the Cumberland County Assessment Office at (717) 240-6350 or visit Room 104 at One Courthouse Square in Carlisle. This is a state program administered at the county level.
