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, & 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.
  • A drop box is also available for making check and money order payments 24 hours a day at the main entrance of the New Castle County Government Center.
  •  If you lose or misplace the self-addressed envelope that was sent with the bills, you can mail your payment to:
    New Castle County Taxes
    P.O. Box 430
    Claymont, DE 19703
  • Major credit cards are accepted through Paymentus, a third-party company that accepts Visa, MasterCard, Discover, American Express, and electronic check. You can pay your property and/or school tax online, or by calling Paymentus toll-free at 877-225-7351. Paymentus charges users a service fee equal to 2.5% of the total payment. If you have any questions concerning making payments through Paymentus, you may call their Customer Contact Center at 800-420-1663.

Billing Schedule

The 2018 tax billing statements will be mailed the third week of July 2018. If you have not received your bill by August 8, 2018, call the New Castle County billing information line at 302-323-2600.

Because the normal September 30 deadline falls on a Sunday, both New Castle County and local school property taxes will be due Monday, October 1, 2018. Any balances that remain on accounts as of October 2, 2018 are subject to a 6% penalty on County line items, a 5% penalty on school line items, and a 1% penalty for all line items each month thereafter.

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.

Monthly Installment Option

If your account is in good standing (no delinquent balance owed) and you wish to pre-pay your property taxes in lower monthly installments rather than one lump sum, New Castle County now offers this convenient option. Pre-payments can be made either by automatic debit through your checking or savings account, or by mailing in monthly payments by check. Click here for more information.
