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.

Property Tax Bill Deadline

County Executive Matt Meyer continues to strive to keep constituents safe during the COVID-19 pandemic and is waiving service fees.

Be safe, stay at home, and make your payment electronically.

New Castle County Executive Meyer to support emergency tax relief ordinances for residents

On March 31, 2020, New Castle County Executive Matt Meyer announced that he will support a slate of emergency ordinances that will help ease the financial burden on New Castle County residents through the duration of the COVID-19 pandemic. County Executive Meyer will also waive certain fines and fees through County Executive administrative powers. The emergency ordinance is expected to go into effect immediately.

“We’re all searching ways to do our part,” said County Executive Meyer. “I am happy to support these emergency ordinances as well as enact the executive orders to help some of our taxpayers in a challenging time.”

The fines and fees suspended through the duration of the COVID-19 pandemic enacted by the emergency ordinances include:

  • Suspension of monthly penalty charges on unpaid sewer fees for residential accounts only
  • Waiving returned check fees
  • Waiving any library fines and fees
  • Suspending collections of county accommodations tax
  • Waiving any fees for building permits for signs

“I am happy we could come together and offer New Castle County residents this little bit of relief during this difficult time,” said District 11 County Councilman David Tackett. “I look forward to working with my Council colleagues and County Executive Meyer to find other ways we can help unburden our citizens in this time of uncertainty.”

The County Executive, through executive order, will waive the following taxes and fees:

  • Waiving Maintenance Corporation Billing Service fees
  • Waive credit card fees for all tax and sewer payments made for so long as the state emergency declaration is in place

The executive order will also suspend Sheriff sales for so long as the state emergency declaration is in place.

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.

Mailing address (For a PROPERTY TAX payment): 

New Castle County
P.O. Box 782888

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.
