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 process Discover Card payments directly. Customers can still use their Discover Card to pay tax or sewer bills, but will need to do so through our 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 of $5.25 for each transaction per $650 increment.
Pre-Payment of Sewer Service Charges
In an effort to assist customers in managing the amount of their annual sewer 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 sewer 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.
