Real estate tax in Washington County, PA is billed by three separate authorities — the county, your borough or township, and your school district — each applying its own millage rate to your property’s 1981 base-year assessed value. County and municipal bills go out around the end of February or early March; school bills follow in late July or early August. Paying within the first two months earns a 2% discount; paying after four months adds a 10% penalty.
Three Bills, One Property
Your annual obligation comes from three independent taxing bodies. Washington County funds courthouse operations, emergency services, and infrastructure. Your borough or township funds local roads, police, zoning, and municipal services. Your school district levies the third tax, which is almost always the largest of the three.
Each body sets its own millage based on its own budget. A mill equals one dollar of tax per $1,000 of assessed value, and the three rates stack. Two properties with identical assessments can face very different total bills depending on the municipality and school district they sit in.1Washington County, PA – Official Website. Tax Revenue
How the County Values Your Property
Washington County uses a base-year assessment system administered by the Tax Revenue Department’s Assessments division.1Washington County, PA – Official Website. Tax Revenue The county last revalued properties in the late 1970s and locked in a base year of January 1, 1981. Every parcel’s assessed value reflects what the property would have been worth on that date, not its value today. New construction and major improvements are also valued as of the 1981 base year, even when the work is recent.2McGuffey School District. Washington County Property Reassessment
To calculate the tax, divide the millage rate by 1,000 and multiply by your 1981 assessed value. On a property assessed at $25,000 with combined millage of 150, the annual tax is $3,750. The base-year approach means rising neighborhood prices don’t automatically push your assessment up, but it also means the number on your bill may not track a decline in the local market. The State Tax Equalization Board publishes a common level ratio each year that becomes relevant if you appeal.
When the Bills Come and When to Pay
County and municipal bills are mailed around the end of February or early March. School district bills arrive at the end of July or early August.3Borough of East Washington, PA. Tax Collection Information Each bill runs through three payment windows:
- Discount period, first two months: pay and take 2% off.
- Face period, months three and four: pay the full amount, no discount, no penalty.
- Penalty period, after four months: a 10% penalty is added.
For a March county and municipal bill, the discount window runs roughly through April, face through June, and the penalty starts July 1. For an August school bill, the discount ends around the end of August, face runs through October, and the penalty applies November 1. Exact dates vary by municipality and school district, so check the due dates printed on your bill.3Borough of East Washington, PA. Tax Collection Information
If you mail your payment, the U.S. Postal Service postmark controls whether you made the deadline. Metered mail dates don’t count.
Paying Online, In Person, or Through Escrow
The Washington County Treasurer’s office accepts online payments for current and delinquent taxes. Credit and debit cards carry a 2.50% processing fee with a $2.00 minimum; ACH electronic check payments cost $1.50 per transaction.4Washington County, PA – Official Website. Treasurer In-person payments are accepted at the County Courthouse during normal business hours.
One recent change matters if you have fallen behind: as of October 2025, the Treasurer’s office no longer accepts personal checks for delinquent tax payments. You will need a certified check, money order, cash, or a debit or credit card.4Washington County, PA – Official Website. Treasurer
If you have a mortgage, your lender likely collects taxes as part of your monthly payment, holds them in escrow, and pays each taxing authority directly. That does not change what you owe. If a millage rate or your assessment changes, your monthly escrow will adjust and you may owe a lump-sum shortage. Watch the annual escrow statement.
Programs That Can Lower the Bill
Several state programs reduce what qualifying owners pay. Eligibility turns on how you use the property, your income, and in some cases your military service.
Homestead and Farmstead Exclusion
The Homestead and Farmstead Exclusion reduces the assessed value of your primary residence for school tax purposes. It was originally created by Act 50 of 1998 and expanded under the Taxpayer Relief Act of 2006. Only your permanent home qualifies; rental properties and vacation homes do not. The exclusion amount varies by school district because it depends on how much gaming revenue the state allocates to your district.5PA Department of Community and Economic Development. Property Tax Relief Through Homestead Exclusion You apply through the county. Once approved, the exclusion renews automatically unless your circumstances change, but if you buy a new home, you need to reapply.
Clean and Green
Pennsylvania’s Clean and Green program (Act 319) taxes qualifying land on its use value rather than its fair market value, which usually produces substantial savings for farmland, forest land, and open space. The property must be at least ten acres in agricultural use, agricultural reserve, or forest reserve. Smaller parcels can still qualify if the land produces at least $2,000 in annual farm income.6Commonwealth of Pennsylvania. Clean and Green
Converting the land to a non-qualifying use later — subdividing for residential development, for instance — triggers rollback taxes covering up to seven years of the tax difference, plus interest. Factor that into any decision to change the use.
Property Tax/Rent Rebate
Pennsylvania offers direct rebates to homeowners and renters who are 65 or older, to widows and widowers 50 or older, and to people with disabilities age 18 and up. Household income must be $48,110 or less. The standard property tax rebate ranges from $380 to $1,000 depending on income.7Commonwealth of Pennsylvania Department of Revenue. Property Tax/Rent Rebate Program
Supplemental rebates of $190 to $500 are added for qualifying applicants with income of $32,070 or less whose property taxes exceed 15% of their income. Residents of Philadelphia, Pittsburgh, and Scranton also qualify for supplemental rebates. At the highest tier, the total can reach $1,500.7Commonwealth of Pennsylvania Department of Revenue.

Disabled Veteran Exemption
Veterans rated 100% permanently and totally disabled by the U.S. Department of Veterans Affairs can receive a full exemption from real estate taxes on their primary residence under 51 Pa.C.S. Chapter 89. The exemption covers all three taxing bodies. Surviving spouses who have not remarried may also qualify. Applications go through the county’s Board of Assessment Appeals.
Appealing Your Assessment
If your assessed value looks high compared with similar properties or with what your home would actually sell for, you can challenge it through the Washington County Board of Assessment Appeals. Start by getting the appeal form from the Tax Revenue Department and entering your parcel number, current assessment, and the value you believe is correct. The county sets an annual filing deadline; miss it and you wait a year.
Evidence carries the hearing. A recent independent appraisal or comparable sales showing that similar properties sold for less than your assessment implies is the most persuasive material you can bring. The board weighs the State Tax Equalization Board’s common level ratio when judging whether your assessment lines up with market value countywide.
If the board rules against you, you can file a petition of appeal in the Washington County Court of Common Pleas within 30 days of receiving the formal decision.8Washington County Courts, PA. Tax Assessment Appeals
What Happens If You Don’t Pay
Unpaid taxes become delinquent on December 31 of the year they were due. By the following April, the local tax collector turns the unpaid account over to the county Tax Claim Bureau. The bureau enters a formal claim against the property and, no later than July 31, sends notice that a one-year discharge period has begun. Fail to pay in full during that year and the property will be advertised for sale.9Pennsylvania General Assembly. Real Estate Tax Sale Law, Act 542 of 1947
If the claim is still unpaid the following January, it becomes absolute and the county can schedule an upset tax sale, typically between September and year-end. The bureau must advertise in two newspapers and the legal journal at least 30 days ahead and must send notice by certified mail with return receipt requested. If certified mail isn’t acknowledged, first-class mail follows and notice is posted on the property.10New York Codes, Rules and Regulations. Pennsylvania Consolidated Statutes 72 PS 5860.602 – Notice of Sale
You can stop the sale at any point by paying the full amount owed plus charges and interest. The bureau may also allow a written agreement to stay the sale if you pay at least 25% of the total up front.9Pennsylvania General Assembly. Real Estate Tax Sale Law, Act 542 of 1947
If a property doesn’t sell at the upset sale or the delinquency continues, it can proceed to a judicial sale scheduled by the Tax Claim Bureau.11Washington County, PA – Official Website. Claims – Judicial Sale A judicial sale strips all liens from the property, which is why letting an account reach that stage is so consequential for the owner.
