New Castle County Reassessment

Date Posted: Wednesday, July 13th, 2022

From New Castle County Councilman Dave Carter,  

As part of a law suit settlement, New Castle County has begun undergoing a property tax reassessment countywide.   Residents may have begun to see data collectors making their way through New Castle County to reassess parcels. 

New Castle County has engaged Tyler Technologies to conduct the reassessment project. 

Beginning on or around July 18, property owners should be on the lookout for data collectors in our community. They will be making their way through Southern New Castle County, visiting every parcel and collecting data. The data collector may also ask the occupants about the property such as the year it was built, the number of bedrooms, or square footage.

Once the data has been collected, a data mailer will be mailed to the property owner with the information that was collected. Please contact the County assessment office (302-395-5520) if there is an error or if something was missed. The most accurate information will ensure the most accurate value for the property.

For more information on this process, please view the FAQ regarding the reassessment, and continue to check the County website for updates.
