County Executive Meyer announces special arrangements for last-minute property tax bill payment

The deadline for payment of the 2020 New Castle County property and State school tax bill is Wednesday, September 30. New Castle County Executive Matt Meyer, along with Chief Financial Officer Michael Smith recently announced special arrangements for people seeking to make their property tax payments. While the New Castle County Government Center will not be open to the public, a “drive-up” environment will be set up where taxpayers are welcomed to “drop off” their payments without having to get out of their vehicle. This service will be offered at the Government Building beginning Monday, September 28th through Friday, October 2nd, between 8:00 a.m. and 4:00 p.m. Tax payments must be received by NCC no later than September 30, 2020.

 Other payment methods include:

  • Use our third-party vendor, Paymentus, to pay using credit cards, debit cards, or e-check services from your checking account with NO FEE
    • Pay online at, and click on “Online Tax and Sewer Payments”
    • Pay over the phone by calling 1-877-225-7351
  • Mail payments to PO BOX 782888 Philadelphia, PA  19178-2888; please do NOT mail cash
  • Use your own banking institution to send an electronic payment to New Castle County at PO Box 782888, Philadelphia, PA 19178-2888
  • Use the 24-hour drop box located in the front of the Government Center Building located at 87 Reads Way, New Castle, DE 19720

County residents are reminded to always put their account number on all payment information for it to be applied timely and accurately.

Cash payments will be accepted, however, County officials are discouraging cash payments, as change is not available while the building is closed.  Any overpayments will be applied to the account as a credit toward future bills.

During the “drop off” environment traffic could be heavy, and you should anticipate long lines.   This is an opportunity for customers to bring their payments to the building, while remaining safe in their cars during the entire experience. 

For concerns, taxpayers can call 302-395-5340 and speak to someone in the County’s Treasury department, keeping in mind as we get closer to the September 30th deadline, call volume will increase. Due to the anticipated high call volume Treasury also encourages people to reach out by sending an email to


If you escrow your property taxes with your mortgage lender and recently received a bill, you are not required to remit payment directly to New Castle County.

On July 23, it came to the Office of Finance’s attention that our contract vendor printed and mailed out approximately half of an image-only mortgage file in error. This mortgage file contained 102,417 parcels, so it is estimated that approximately 51,000 bills were mailed to these citizens in error. The Office of Finance is working with the vendor to identify all affected individuals so that a letter can be sent to them explaining the error and that there is no need for them to remit payment because their mortgage company will remit on their behalf. 

If you are unsure if you escrow your property taxes or would like more information, please contact the Treasury Department at (302) 395-5340.

Pre-Payment of Property Taxes

In an effort to assist customers in managing the amount of their annual property tax bill amounts, New Castle County allows you to pay on your account in advance.

Any advance payment made will post to your account as a credit and apply to the next bill generated on your account. The County accepts “pre-payments” by all accepted payment types listed in the above “Methods of Payment” section.

You may also choose to make pre-payments through an online payment service, possibly through your bank. If you choose to make payments to us in this manner, you will need to have your account number (for property tax bills, this is referred to as your “parcel number”), and our name and mailing address for payments.

You may get your account/parcel number from your bill or from our website. You may search for your account/parcel number on our website with your property address.
