When are property taxes due in Chester County?
Every due date for the 2026 bill has passed, and Chester County had not posted the next cycle's dates when we checked on September 23, 2026. If that bill is still unpaid, the late-payment rules below apply to it. Counties usually repeat the schedule, but confirm the new dates on your next bill. For the 2026 bill, Chester County has one due date: May 15, 2026. The Treasurer mails county tax bills on January 15. Paying the whole bill within 60 days of that date earns a 2% discount; the face amount is due during the next 60 days. This date follows the county's published rule of two months at discount and two months at face from the bill date; the exact discount and face dates for your property are printed on your bill. Partial payments are not accepted. After the face period a 10% penalty is added. The Treasurer accepts payment with the penalty until December 31, and a payment must be postmarked or made by that day, with no exceptions. Unpaid taxes are then returned to the county Tax Claim Bureau in January, where interest of 3/4 of 1% a month (9% a year) accrues.
From Chester County's published schedule, checked September 23, 2026. The county had not posted a calendar labeled for this cycle when we checked, so these dates come from state law and the county's standing schedule; the date on your bill is the one that binds you.
