New Castle County, Delaware’s most populous county, has agreed to reassess property values for taxation purposes for the first time in more than 30 years, settling part of a lawsuit seeking to revamp the state’s school funding system. The reassessment will take effect in fiscal year 2024. The lawsuit alleged that Delaware underfunded schools that have large populations of students with disabilities, students from low-income households or English language learners. Local property taxes make up about a third of Delaware school districts’ funding.
