New Castle County
Property Reassessment

All things change with time. New Castle County’s Assessment system is no exception. New Castle County has contracted with Tyler Technologies to conduct a reassessment project to update property assessments from a base year of 1983, providing an efficient technical process with current, accurate property values.

The purpose of conducting the reassessment is to remedy a Delaware Chancery Court ruling in 2020 that found property taxing systems in each of the state's three counties to be unconstitutional and not in compliance with Delaware law.

Property Owners should be on the lookout for our data collectors. They will be making their way through New Castle County, visiting every property, measuring improvements on the property and collecting data. The data collector may also ask the occupants several questions about the property.

Once the data has been collected, a data mailer will be mailed to the property owner with the information that was collected. Please let us know if there is an error or if something was missed. The most accurate information will ensure the most accurate value for the property.

After all the data is collected and data mailers have been returned and reviewed, Tyler Technologies will begin analyzing the data. 

For more information, please download our frequently asked questions document and check back for updates as the project progresses. Key dates as well as pictures of the Data Collectors will be uploaded to this website. If you have any doubt if a data collector is in your area, please feel free to call your County Assessment Office at 302-395-5520.
