DE SB228

New Castle County's Office of Finance is authorized to conduct quality control reviews of property assessments from the recent general reassessment, particularly targeting non-residential parcels valued at $300,000+ that decreased in value or increased less than expected.

Reviews may be triggered when a non-residential property's assessed value is at least 25% below its actual sale price from the past 5 years, or when clerical, mathematical, or factual errors occurred during reassessment.

All assessment revisions and corrections must be completed by September 30, 2026, with affected property owners receiving notice and appeal rights.

Tax payment deadlines for New Castle County are extended, with taxes due October 12, 2026, statements mailed by November 16, 2026, and final payment due December 31, 2026.

The legislation expires March 31, 2027, and school districts within New Castle County experiencing funding shortfalls due to the delayed timeline may request advances from State Division I funds.
