Reassessment Project

Sussex County will begin a court-ordered reassessment of residential, agricultural and commercial properties in 2021. The reassessment was ordered in 2020 to address the issue that the County assessments were not representative of the “true value of money.”

The reassessment process is being conducted by Tyler Technologies, nationally recognized experts, which will survey approximately 182,000 properties over a three-year period. New assessment values are being set at what is projected to be the fair market value of the property (i.e. the amount the property could be sold for) as of July 1, 2023.

The county and the school districts are capped by law on how much additional revenue can be generated from reassessment. Following the reassessment, property tax rates will be adjusted to ensure the taxing entity does not collect more than allowed by statute. Per State Code, the County cannot yield property tax revenues greater than 15 percent of the preceding year in which the reassessment occurred. The State Code caps school districts to a 10 percent revenue increase due to a reassessment.

Once the assessed value of a property is established, a corresponding tax bill will be generated in 2024. While it is too early to determine whether the value of an individual property may increase, decrease, or stay the same, there will be multiple opportunities to appeal your property's valuation if it appears to be too high, including through both an informal and formal process.

Public presentations are scheduled to discuss the reassessment process at the following times and locations:

  • Thursday, Sept. 23, 2021, from 2 to 4 p.m., at Milton Fire Department, 116 Front St., Milton;
  • Thursday, Sept. 23, 2021, from 6 to 8 p.m., at Delaware Technical Community College-Owens Campus, 21179 College Drive, Georgetown;
  • Monday, Sept. 27, 2021, from 6 to 8 p.m., at the Delaware National Guard-Bethany Beach Training Site, 163 Scannell Boulevard, Bethany Beach;
  • Wednesday, Sept. 29, 2021, from 6 to 8 p.m., at Millsboro Town Center, 322 Wilson Highway, Millsboro;
  • Thursday, Sept. 30, 2021, from 6 to 8 p.m., at Seaford Volunteer Fire Department, 302 King St., Seaford.

In addition to the in-person sessions, one virtual session featuring the same presentation will be conducted, as well. That meeting will be held: Monday, Sept. 27, 2021, from 2 to 4 p.m., available on any computer or mobile device at

Additional information on the reassessment project is available on the Sussex County Property Reassessment website.
