Property Tax Appeals · Delaware
Appeal your property taxes
in Delaware.
Delaware has just three counties — New Castle, Kent, and Sussex — and each runs its own assessment office and Board of Assessment Review. After decades of frozen, decades-old base-year values, all three counties recently completed court-ordered general reassessments, putting every property on current market value at once. That kind of mass revaluation is precisely when individual errors are made, so checking the new number is worth it. You appeal by filing with your county’s assessment office and presenting evidence to the Board of Assessment Review.
Appeal deadlines are set county-by-county in Delaware’s three counties — your reassessment notice states yours.
School taxes make up the bulk of a Delaware property tax bill, so an assessment cut flows through several taxing lines at once. The review board’s question is your home’s market value on the county’s valuation date — documented comparable sales, the substance of a licensed appraisal, are what it can act on.
The evidence
Boards act on value,
not frustration.
However Delaware labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today

All three counties completed court-ordered general reassessments after decades without one, resetting values to current market levels. New mass-appraisal values are exactly the ones worth verifying against real comparable sales.
File an appeal with your county assessment office by the deadline on your notice, then present market-value evidence to the county Board of Assessment Review. Deadlines and procedures differ among New Castle, Kent, and Sussex.
