Property taxes in Lancaster County are the combined total of three separate bills: one from the county, one from your municipality, and one from your school district. Each body sets its own millage rate every year, and the school district portion is almost always the largest piece. Your bill is calculated by multiplying your property’s assessed value by the total millage and dividing by 1,000, then adjusted by any relief programs you qualify for and by when you pay.1Lancaster County, PA – Official Website. Property Assessment
How Your Bill Is Calculated
A mill equals one dollar of tax for every $1,000 of assessed value. On a home assessed at $150,000 with a combined rate of 25 mills across all three taxing bodies, the annual tax works out to $3,750.
The county commissioners set the county rate, your municipal governing body sets the local rate, and your school board sets the school rate. All three are adopted separately during annual budget sessions and can change from year to year. Lancaster County publishes current millage for every municipality and school district on its website, so you can look up the exact rates that apply to your address.2Lancaster County, PA – Official Website. Millage Rates
Why Your Assessed Value Reflects 2018
The Lancaster County Property Assessment Office determines the taxable value of every parcel. All assessed values are currently based on property market values as of January 1, 2018.3Lancaster County, PA – Official Website. Property Assessment The figure on your bill is what the county determined your property was worth during that base year, not what it would sell for today.
In neighborhoods where prices have climbed since 2018, the gap can be large. That alone doesn’t mean your taxes are wrong, because every property in the county is measured against the same base year. What it does mean is that any appeal or new construction valuation gets pegged back to 2018 conditions, not current market value.
Interim Assessments After Improvements
Finishing a basement, adding a deck, or building an addition triggers an interim assessment. The Assessment Office recalculates your property’s value to account for the improvement, and that added value should reflect only what the work contributed, not a full re-rating of the whole property. Once you receive the notice, you have 40 days to appeal the new figure if you disagree with it.1Lancaster County, PA – Official Website. Property Assessment
When to Pay, and What It Costs If You Wait
Lancaster County tax bills carry three payment windows, and when you pay changes what you owe. Pennsylvania’s Local Tax Collection Law requires at least a 2% discount for paying within two months of the notice date and allows up to a 10% penalty on bills unpaid after four months.4Pennsylvania General Assembly. Local Tax Collection Law, Act of May 25, 1945, P.L. 1050, No. 394 The Lancaster County Tax Collection Bureau applies those windows this way:5Lancaster County Tax Collection Bureau. Real Estate Tax Office
- Discount period, through August 31: pay the full amount and take a 2% discount.
- Face period, September 1 through October 31: pay the base amount with no discount and no penalty.
- Penalty period, November 1 through December 31: a penalty is added to the outstanding balance.
Some school districts offer installment plans. The School District of Lancaster, for example, splits the base amount into three equal payments due August 15, October 15, and December 15, and you have to make the first installment on time to stay on the plan.6School District of Lancaster. Real Estate Taxes Terms vary across the 17 districts, so check with yours.
How to Pay
Find your Uniform Parcel Number (Parcel ID) on your tax bill before paying so the money is credited correctly. If you’ve misplaced the bill, both the Lancaster County Treasurer’s website and the Tax Collection Bureau’s online portal have search tools.

Lancaster County Tax Collection Bureau Mailed checks are credited by the U.S. Postal Service postmark date, and you can pay in person at the county administration building during business hours. Write your Parcel ID on the check.
If Your Mortgage Has an Escrow Account
With an escrow account, your lender collects a portion of estimated annual property taxes with each mortgage payment and pays the tax bills on your behalf. The lender runs an annual escrow analysis and will tell you if your monthly amount is changing. If taxes rise and the escrow balance can’t cover them, you’ll either pay a lump sum or absorb the shortfall across next year’s monthly payments. Supplemental bills the escrow doesn’t cover remain your responsibility, so review your records rather than assuming everything is handled.
Programs That Can Reduce What You Owe
Several state programs lower what Lancaster County homeowners actually pay. Some trim the assessed value before millage is applied; others send cash rebates after the fact. Most homeowners qualify for at least one.
Homestead and Farmstead Exclusion
The Taxpayer Relief Act (Act 1 of Special Session 1 of 2006) reduces the assessed value of owner-occupied homes and qualifying farmsteads before the school district rate is applied, which directly lowers the school portion of your bill.9Pennsylvania Department of Community and Economic Development. Property Tax Relief Through Homestead Exclusion The dollar value of the exclusion varies by district because it depends on state gambling revenue allocations. The School District of Lancaster’s exclusion was $847.93 for the 2025 tax year.6School District of Lancaster. Real Estate Taxes Only your primary residence qualifies; rentals and second homes do not.
Clean and Green (Act 319)
The Pennsylvania Farmland and Forest Land Assessment Act gives preferential tax treatment to land used for agriculture, forestry, or open-space preservation. A property must be at least ten acres, or if smaller, generate at least $2,000 a year in farm income.10Commonwealth of Pennsylvania. Clean and Green Enrolled land is taxed on its use value rather than its development potential, which can mean much lower assessments for farmland near growing suburbs. Converting enrolled land to a non-qualifying use triggers rollback taxes: you’ll owe the difference between the preferential and normal assessments for up to seven years.
Disabled Veteran Exemption
Veterans with a 100% permanent and total service-connected disability rating from the U.S. Department of Veterans Affairs can receive a complete exemption from real estate taxes on their primary residence. The local board of assessment grants the exemption after receiving certification of need from the State Veterans’ Commission.11Pennsylvania General Assembly. Pennsylvania Code 51 Section 8903 – Duty of Board It covers county, municipal, and school district taxes on the qualifying dwelling. Surviving spouses who have not remarried may also be eligible. Applications go through the Lancaster County Board of Assessment Appeals.
Property Tax/Rent Rebate Program
Pennsylvania’s Property Tax/Rent Rebate Program sends cash rebates to older adults, widows and widowers age 50 and over, and people with disabilities age 18 and over. Household income must be $48,110 or less annually, and you can exclude half of your Social Security income when calculating eligibility. Standard rebates run from $380 to $1,000, with supplemental rebates of $190 to $500 for those who qualify. The maximum combined rebate is $1,500 for households with income between $0 and $8,550. The deadline to file for the 2025 tax year rebate is June 30, 2026.12Pennsylvania Department of Revenue. Property Tax/Rent Rebate Program
Appealing an Assessment You Think Is Too High
If your assessed value looks too high, either because comparable properties are assessed lower or because the 2018 base-year number was off, you can challenge it through the Board of Assessment Appeals.
Annual Appeals
The deadline for an annual appeal is 5:00 p.m. on August 1. The official appeal form must reach the Board of Assessment Appeals by that time.13Lancaster County. Lancaster County Board of Assessment Appeals Appeal Procedures, Rules, and Regulations You can start the filing with a letter, but the official form still has to be returned before a hearing is scheduled; if it isn’t, the county treats the appeal as abandoned. Filing fees vary by property classification.
At the hearing, you present evidence that the assessed value doesn’t reflect the property’s 2018 base-year market value. The strongest evidence tends to be a professional appraisal (expect $250 to $1,200 depending on property complexity), recent sale prices for comparable properties, and documentation of condition issues that reduce value. The board mails a written decision, and a successful appeal applies to the following tax year.14Lancaster County, PA – Official Website. Property Assessment – Yearly Appeals and Pricing Information
Interim Appeals
When the Assessment Office changes your value because of new construction or improvements, you don’t wait for the August 1 cycle. You have 40 days from the date on the assessment change notice.1Lancaster County, PA – Official Website. Property Assessment The evidence standards are the same, but the argument is narrower: you’re challenging the value added for the improvement, not the whole assessment.
Using the Common Level Ratio
Because the county uses a 2018 base year while properties sell at current prices, the state publishes a Common Level Ratio that bridges the two. For July 1, 2025 through June 30, 2026, Lancaster County’s CLR factor is 1.87.15County of Lancaster, Office of Recorder of Deeds. Common Level Ratio (CLR) Real Estate Valuation Factors for Lancaster County The ratio is mainly used for realty transfer tax calculations, but it gives useful context in an appeal by showing roughly how assessed values relate to current sale prices.
What Happens If You Fall Behind
Taxes become delinquent on December 31 of the year they were due, and the unpaid balance is turned over to the Lancaster County Tax Claim Bureau.16Lancaster County, PA – Official Website. Tax Claim Bureau Interest starts accruing monthly on the first of each month.
Pennsylvania’s Real Estate Tax Sale Law takes over from there. Once the tax claim becomes absolute, generally after remaining unpaid for two or more years, the bureau can schedule the property for an upset tax sale, held between the second Monday of September and October 1. The bureau sets an upset price equal to all outstanding tax liens, accrued taxes, municipal claims, and sale costs, and no bid below that price is accepted.17Pennsylvania General Assembly. Real Estate Tax Sale Law, Act of Jul. 7, 1947, P.L. 1368, No. 542 If the property sells, a former owner who lived in the home may have a limited window, typically nine months from the sale date, to reclaim it by paying the full purchase price plus 10% and additional costs. If you’re falling behind, call the Tax Claim Bureau early about a payment arrangement; it’s far cheaper than fighting a tax sale.
