Reassessment Updates 20 August 2025

 

Following the recent property reassessment in New Castle County, Delaware, several school districts have been revising their tax rates to address a shift in the tax burden towards homeowners. WDEL has been reporting on these developments: 

• Red Clay School District: WDEL reported on August 20, 2025, that the Red Clay School District voted to lower residents' school tax bills by shifting more of the burden back to businesses. The new tax rate for residents is $0.59180 per $100 of assessed value.
• Brandywine School District: WDEL reported on August 18, 2025, that the Brandywine School District changed its property tax rates and removed a post-reassessment increase, which means landowners will be receiving new tax bills.
• Colonial School District: WDEL reported on August 20, 2025, that the Colonial School Board voted to change their tax rates, but unlike Brandywine, they opted to keep some of the increase that was implemented after the reassessment.
• Appoquinimink and Christina School Districts: WDEL indicated that both districts were scheduled to hold meetings on Thursday to discuss their tax rates, with both needing to address the split rates and the fact that both had implemented a 10% increase after the reassessment. 

Important Notes:

• New Castle County school districts were authorized by the state legislature to create different school tax rates for residential and non-residential properties.
• The due date for both County and school district taxes has been extended to November 30, 2025.
• New tax bills will be designated "supplemental school tax bills" and will be reflected as such online and in mailed bills.
• If you have already paid the higher tax bill and the revised bill is more than $50 cheaper, you can request a refund or have the overpayment credited to next year's bills.
• For questions regarding your tax bill, you can contact New Castle County's Constituent Services Office at (302) 395-5114 or the Treasury Division at (302) 395-5340. You can also find updated information and contact details on the New Castle County website.
