Delaware Expertise with a National Footprint
Currently, Kent, New Castle, and Sussex counties are undergoing complete revaluations of properties. This initiative was triggered by a State Supreme Court order that directed New Castle County to reassess properties following a lawsuit filed by the City of Wilmington School District. The lawsuit raised concerns about uniformity and underassessment issues in property assessments. Throughout this revaluation process, some incorporated towns have conducted reassessments independently, leading to instances where parcels have two distinct assessors, collectors, and property values.
Current guidance on New Castle County’s revaluation has the third-party contractor, Tyler Technologies, mailing new value notices for summer 2024 and informal meeting notices for fall/winter 2024, with new values in place for the 2025 tax year.
Based on State House Bill 62 approved in August of 2023, all three counties will now be held to five-year revaluation cycles. The bill amends Title 9 of the Delaware Code on real property assessment and states that the five-year revaluation cycle will begin upon the completion date of the current countywide revaluations.
