New Castle County property taxes are due Sept. 30, but will be accepted until Oct. 1 without penalty.

The county property taxes and state of Delaware school taxes are due at the end of September, but since the Sept. 30 deadline falls on a weekend this year, payments will be accepted without penalty until Monday, Oct. 1.

After Oct. 1, any balance that remains on accounts will be subject to a 6 percent penalty and a 1 percent penalty each month after.

County property taxes and school taxes are combined into one billing statement. Property owners may pay both amounts with a single check or money order.
