As part of County Treasurer Patricia Maisano's commitment to provide citizens with efficient, convenient service, Chester County offers secure electronic payment of taxes using credit cards and electronic checks. Additionally, we accept payment for 18 municipalities. For credit card transactions, the customer is charged a fee of 2.25% of the payment amount or a flat fee of $1.50 for an electronic check transaction. Chester County does not receive this fee. Payment will be credited within two business days of the transaction. Partial payments will not be accepted. You are required to enter the invoice number from your current tax bill when paying. A confirmation email will be sent and will served as a record of your payment. The charge will appear on your credit card or bank statement as two charges: the tax amount, and the convenience fee.
