How Property Tax Works

Chester County, Pennsylvania operates on a property tax system that serves as the primary funding mechanism for essential local services including schools, municipal operations, emergency services, and county administration. Property taxes in Chester County are collected annually based on assessed property values and current mill rates established by the county, local municipalities, and school districts.

The effective property tax rate in Chester County varies by location within the county due to different combinations of municipal, school district, and special taxing district rates. For 2025, the county mill rate is 1.49 mills, but total effective rates typically range from approximately 15-25 mills when combined with municipal and school district taxes. Property owners should note that their actual tax rate depends on their specific location within Chester County, as different townships, boroughs, and school districts maintain separate mill rates that are added to the county rate.

Supplemental Tax Bills

Supplemental taxes in Chester County are additional property tax assessments that occur when there are changes to a property's assessed value during the tax year. The most common triggers include new construction, major renovations that add significant value, property improvements, or corrections to assessment errors discovered mid-year.

When a supplemental assessment is issued, the additional tax is calculated by applying the current mill rate to the increased assessed value, prorated for the portion of the tax year remaining after the change occurred. For example, if a $100,000 home addition is completed in January and the total mill rate is 20 mills, the supplemental tax would be approximately $2,000 ($100,000 ÷ 1,000 × 20 mills) for that tax year. Property owners typically receive a separate supplemental tax bill that must be paid according to the same schedule as regular property taxes.

Example Calculation

Example 1: $300,000 Property

  • Assessed Value: $300,000
  • Assumed Total Mill Rate: 18 mills
  • Annual Tax: $300,000 ÷ 1,000 × 18 = $5,400
  • Monthly Escrow: $450

Example 2: $600,000 Property with Homestead Credit

  • Assessed Value: $600,000
  • Homestead Credit Applied: Caps assessment increases (varies by application)
  • Assumed Total Mill Rate: 20 mills
  • Annual Tax: $600,000 ÷ 1,000 × 20 = $12,000
  • Monthly Escrow: $1,000

Example 3: $1,000,000 Property

  • Assessed Value: $1,000,000
  • Assumed Total Mill Rate: 22 mills
  • Annual Tax: $1,000,000 ÷ 1,000 × 22 = $22,000
  • Monthly Escrow: $1,833

Note: Tax credits such as homestead must be applied for annually and are not automatic. Actual mill rates vary by specific location within Chester County.

Escrow & Property Taxes

Most mortgage lenders in Chester County require property tax escrow accounts to ensure timely payment of annual property taxes. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in an escrow account until taxes are due. Lenders typically pay property taxes directly to the county tax collector before the discount deadline to take advantage of available savings.

Property owners should review their annual escrow analysis statement to verify that adequate funds are being collected, especially after reassessments or mill rate changes. If property taxes increase significantly, you may need to increase monthly escrow payments or pay a shortage. When property taxes decrease or if you've overpaid, you may receive a refund or reduction in future escrow payments. Contact your lender immediately if you notice discrepancies in your escrow account or property tax payments.

Q: What is the homestead credit and how do I apply? A: The homestead credit caps annual assessment increases on your primary residence, limiting the growth rate rather than reducing market value.

Q: Are there other tax credits available that require application? A: Yes, various tax credits may be available for seniors, veterans, disabled individuals, and other qualifying circumstances. These are tax credits that reduce your tax bill, not exemptions that reduce assessed value. All require separate applications with specific deadlines.

Q: How often are properties reassessed in Chester County? A: Chester County conducts periodic countywide reassessments, though the schedule varies. Individual properties may also be reassessed due to improvements, sales, or appeals. Contact the Assessment Office for current reassessment schedules.

Q: Can I appeal my property assessment? A: Yes, property owners can appeal their assessments through the Chester County Board of Assessment Appeals. Appeals must typically be filed within specific timeframes after receiving assessment notices.

Q: What are the penalties for late property tax payments? A: Late payments incur interest and penalties that accumulate monthly. Severely delinquent taxes may result in tax liens or potential tax sales. Contact your local tax collector for specific penalty rates and collection procedures.
