Cumberland County, PA property tax rates for 2026 start with a county millage of 2.875 mills, but that number alone won’t tell you what you owe. Every property in the county is taxed by three separate bodies: the county, your municipality, and your school district. The school portion is almost always the biggest, and the municipal rate depends entirely on where you live. Two homes with identical assessed values can end up with very different bills.
The 2026 County Millage Rate
The Board of Commissioners sets one countywide rate that applies to every taxable parcel. For 2026, that rate is 2.875 mills, or 0.002875 as a decimal.1Cumberland County. 2026 County and Municipal and 2025-26 School Tax Rates Multiply your property’s assessed value by 0.002875 to get the county portion of your bill. A home assessed at $200,000 owes $575 in county tax.
That figure is uniform across the county. Whether your parcel is in Carlisle Borough or a rural township, the county line on your bill uses the same 2.875 mills.
Municipal Tax Rates
Municipal rates for 2026 range from zero to 7.581 mills. Three townships (Hopewell, Lower Mifflin, and Upper Mifflin) charge no municipal real estate tax at all. Newville Borough sits at the top with 7.581 mills.1Cumberland County. 2026 County and Municipal and 2025-26 School Tax Rates Most boroughs and townships fall somewhere between those endpoints, funding local road maintenance, zoning enforcement, and emergency services through their levy.
School District Tax Rates
School taxes are the largest line on almost every Cumberland County property tax bill. For the 2025–26 school year, district rates range from 12.414 to 20.455 mills.1Cumberland County. 2026 County and Municipal and 2025-26 School Tax Rates Rates for the major districts:
- Cumberland Valley (Hampden, Silver Spring, Middlesex, Monroe): 12.414 mills
- South Middleton Township (Cumberland Valley): 13.563 mills
- West Shore (Lemoyne, Lower Allen, New Cumberland, Wormleysburg): 14.766 mills
- Shippensburg Area (Shippensburg Borough/Township, Southampton, Hopewell): 14.781 mills
- East Pennsboro Area: 15.177 mills
- Big Spring (Newville, Cooke, Penn, and surrounding townships): 16.287 mills
- Mechanicsburg Area (Mechanicsburg, Shiremanstown, Upper Allen): 17.049 mills
- Carlisle Area (Carlisle Borough, Dickinson, North Middleton): 17.369 mills
- Camp Hill Borough (West Shore): 20.455 mills
What a Real Bill Looks Like
Take a $200,000 assessed value in Hampden Township. The owner pays $575 in county tax plus roughly $2,483 in school tax, plus whatever Hampden charges municipally. The same $200,000 assessment in Camp Hill produces $575 in county tax plus about $4,091 in school tax. That’s a gap of more than $1,600 on the school portion alone, before either municipal rate is added.
The lesson: the county rate is the same everywhere, but your total bill is driven mostly by which school district you’re in.
How Assessed Value Is Determined
All three taxing bodies apply their millage to the same base: the assessed value set by the Cumberland County Tax Assessment Office. Pennsylvania law requires assessments to be uniform, so similar properties should carry similar values.
Cumberland County uses a base-year system, with property values pegged to approximately 2011 market conditions from the county’s most recent reassessment. Your assessed value does not automatically move when the market moves. It stays fixed unless you make physical improvements (an addition, a new structure) or the county conducts a full reassessment. A neighbor who bought recently at today’s prices is taxed on the same base-year figure as everyone else on the street.
The Common Level Ratio
Because base-year values drift from real market prices over time, the state publishes a Common Level Ratio (CLR) for each county. The State Tax Equalization Board releases updated ratios every July 1, and the Pennsylvania Department of Revenue publishes them for use in realty transfer tax and assessment appeals.2Cumberland County, PA – Official Website. Common Level Ratio The CLR matters most if you’re appealing your assessment or buying property, because it converts current market value into the base-year equivalent the county actually taxes. The current ratio is posted on the Pennsylvania Department of Revenue’s website.3Commonwealth of Pennsylvania. Common Level Ratios
Ways to Reduce What You Owe
Appealing Your Assessment
If your assessed value looks too high compared to similar properties, you can appeal to the Cumberland County Board of Assessment Appeals. The deadline is September 1 each year, and the completed form must reach the Assessment Office by 4:30 p.m. that day.4Cumberland County, PA – Official Website. Frequently Asked Questions – Property Assessment Appeal Deadline A filing fee applies, payable to the Cumberland County General Fund.5Cumberland County, PA – Official Website. Property Appeal Information A recent sale price well below your assessed value (adjusted by the CLR) is strong evidence; professional appraisals can also be submitted.
Homestead Exclusion
The Homestead Exclusion reduces the assessed value used to calculate your school district taxes, cutting that portion of your bill directly. It was created under the Taxpayer Relief Act (Act 1 of Special Session 1 of 2006).6Pennsylvania Department of Community and Economic Development. Property Tax Relief Through Homestead Exclusion The property must be your primary residence, and you apply by March 1 before the tax year you want relief in. Once approved, it stays in place until your eligibility changes; there’s no annual reapplication. Working farms may qualify for a separate farmstead exclusion under the same law.7Pennsylvania General Assembly. Taxpayer Relief Act
Property Tax/Rent Rebate Program
Older adults and people with disabilities may qualify for a state rebate on property taxes paid. Household income must be $48,110 or less, and you must be age 65 or older, a widow or widower age 50 or older, or a person with a disability age 18 or older.8Commonwealth of Pennsylvania. Property Tax/Rent Rebate Program For the 2026 cycle (covering property taxes paid in 2025), the deadline is June 30, 2026. The rebate comes as a state check after the fact, so you still pay the full bill up front. Renters meeting the same income and age tests can also apply.
Clean and Green
Owners of larger tracts used for farming, forestry, or open-space preservation can enroll in Pennsylvania’s Clean and Green program (Act 319), which taxes enrolled land at use value rather than market value.9Commonwealth of Pennsylvania. Clean and Green The property generally must be at least ten acres. Smaller parcels can still qualify under the agricultural use category if they produce at least $2,000 in annual farm income. Leaving the program (through a change in use or a development sale) triggers rollback taxes covering seven years plus 6% simple interest per year on the affected acreage, so the exit needs planning.
When Payments Are Due
Pennsylvania’s Local Tax Collection Law splits payment into three windows measured from the mailing date of your tax notice. The first two months carry at least a 2% discount. Months three and four are the face-value period. After four months, a penalty of up to 10% is added. Timing is set by postmark, not by when the tax collector receives payment, and the discount is only available if you pay the full bill at once.
Bills typically go to a local tax collector assigned to your municipality, not to the county directly.
If You Don’t Pay
Unpaid taxes become delinquent on December 31 of the year they were due. The following spring, your local collector returns the account to the Cumberland County Tax Claim Bureau. By late July, the bureau sends notice starting a one-year period to pay the full balance. If the debt is still unpaid at the end of that period, the claim becomes absolute on January 1, and the property can be listed for an upset tax sale held between the second Monday of September and October 1.10Pennsylvania General Assembly. Real Estate Tax Sale Law Interest and fees accrue the entire time, so paying late is always cheaper than paying at the end.
