New Castle County property tax payment deadline Oct. 1

Reading Time: 2 minutes

New Castle County taxpayers face an Oct. 1 deadline for 2018 State of Delaware school taxes and New Castle County property taxes.

Since the September 30 deadline falls on a weekend this year, payments are being accepted by the county Finance Department without penalty through Monday, October 1, 2018. By county law, any unpaid balance after that deadline is subject to a six percent penalty, and an additional one percent penalty each month thereafter.

This year’s billing statements were sent to all New Castle County property owners in July.

School district property taxes account for approximately 75 percent of the average total property tax bill, and New Castle County property taxes account for approximately 25 percent of the average total property tax bill.

County property taxes are the largest source of county government revenue and funds over 60 percent of general fund expenditures, including police, paramedics and 911 communications, along with libraries, parks and many of the public services provided to residents.

New Castle County provides a variety of convenient ways for property owners to pay their property tax bills on time and avoid late fees.
