How Kent County Assesses Property
Assessed by: Kent County Assessment Office
Assessment cycle: periodic reassessment
Notices typically mailed: varies by reassessment cycle
Kent County assesses property at 100% of fair market value as determined by the Kent County Assessment Office. Delaware recently updated assessment practices requiring 100% assessment ratio across all counties. For example, if your home's market value is $290,600, at Delaware's 100% assessment ratio your assessed value would be $290,600, resulting in approximately $1,337 in annual taxes at the county's effective rate of 0.46%.
The Appeal Process
Appeals are heard by the Board of Assessment Review. The Board of Assessment Review consists of seven Kent County residents appointed by commissioners who serve as impartial judges. They hear disputes presented by appellants and decide based on evidence, with decisions subject to Superior Court appeal within 30 days.
Step 1: Review your property assessment notice from Kent County Assessment Office and verify all property details including square footage, lot size, bedroom count, year built, and property condition for accuracy.
Step 2: Research comparable sales in your area from recent months showing properties similar to yours that sold for less than your assessed value. For residential appeals, comparable sales are required evidence.
Step 3: Gather supporting evidence including comparable sales data, photographs of your property showing condition issues, repair estimates, appraisals, and any documentation that supports a lower valuation.
Step 4: File your appeal with the Kent County Assessment Office by the applicable deadline. Submit your appeal form and supporting documentation online at https://www.co.kent.de.us/assessment.aspx, by mail, or in person at 555 Bay Road, Dover, DE 19901.
Step 5: The assessor will review your appeal and supporting documents. If you and the assessor agree on a value, you'll sign a stipulation form that goes to the Board of Assessment Review for approval.
Step 6: If no agreement is reached with the assessor, your appeal advances to a formal hearing before the Kent County Board of Assessment Review, a seven-member panel that acts as an impartial judge between you and the Assessment Office.
Step 7: Attend your hearing before the Board of Assessment Review, present your evidence clearly, and be prepared to answer questions about your comparable sales and property condition. The Board will issue a written decision.
Step 8: If you disagree with the Board's decision, you have 30 days from notification to file an appeal with the Superior Court of Kent County to pursue your appeal further.
