Check Your Payment Status

Taxpayers can access their property tax information and payment status online. Property owners who misplace or who do not receive their bills can download a printable version via the site, which also provides detailed account information including payment history and a breakout of specific charges for property, school, light, and crossing guard taxes. If your tax bills are paid by a mortgage company or bank, you are still responsible to make sure the bill is paid.

Methods of Payment

  • Walk-in payments are accepted at the New Castle County Government Center, located at 87 Reads Way in New Castle. Payments by cash, check, money order, and debit card are accepted. The payment window is open between the hours of 8 a.m. and 4 p.m., Monday through Friday. Please note: The payment window will be open from 8 a.m. to 6 p.m. on Friday, September 29 and Monday, October 2.

Change to Discover Card Payments

Discover has discontinued the government payment program that New Castle County has been using to accept and process Discover Card payments by phone and at the New Castle County Government Center.  As a result, New Castle County will no longer be able to accept Discover Card payments directly by phone or at the Government Center payment window.  Customers can still use their Discover Card to pay tax or sewer bills, but will need to do so through the Paymentus payment platform. 

To make a payment with a Discover Card, customers may call Paymentus at (877) 225-7351, or through the County website by clicking here.  Paymentus charges users a service fee equal to 2.5% of the total tax payment.

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 by clicking HERE.
