Delaware average effective property tax rate is 0.57%. On a home valued at $295,000, that works out to about $1,682 per year. Whether that feels high or manageable depends on your situation, but the fact remains: if you are not using every tool available to reduce your bill, you are likely overpaying.
Here is every method available to reduce your Delaware property tax bill in 2026.
Method 1: Claim the Senior School Tax Exemption
Delaware homeowners 65 and older are exempt from the school portion of property taxes on their primary residence. Since school taxes make up the majority of property tax bills in Delaware, this exemption provides major savings. Apply with your county.
Method 2: Appeal Your Assessment
File with your County Board of Assessment Review within 30 days of your assessment notice. Delaware assessments are notoriously outdated (some based on 1980s values), creating significant inequities. See our Delaware property tax appeal guide.
Method 3: Push for Reassessment Equity
Delaware counties have some of the oldest base-year assessments in the country. New Castle County last reassessed in 1983. If your property is overvalued relative to others under this outdated system, an equity argument can be powerful.
Method 4: Disabled Veteran Exemption
Disabled veterans receive exemptions that vary by county and disability rating. Contact your county assessment office for specific amounts and application requirements.
Method 5: Check for Data Errors
With assessments based on decades-old data, property records may contain outdated or incorrect information about your home size, features, or condition. Verify your property card.
How Much Can You Save?
| Strategy | Potential Annual Savings |
|---|---|
| Senior School Tax Exemption | $200-$2,000+ |
| Assessment Appeal (10% reduction) | $168+ |
| Senior/Disability Exemptions | $500-$5,000+ |
| Correcting Property Record Errors | $100-$1,000+ |
These strategies stack. You can claim exemptions and appeal your assessment at the same time. The combined savings can be significant.

Frequently Asked Questions
What is the easiest way to lower property taxes in Delaware?
File for every exemption you qualify for. Many homeowners miss exemptions they are entitled to simply because they never applied. Check with your county assessor office for a complete list of available exemptions.
How often should I appeal my property tax assessment?
Check your assessment every year. If it seems too high compared to what your home would actually sell for, or compared to similar homes in your area, file an appeal. There is generally no penalty for appealing, and your assessment cannot go up as a result.
Can I lower my property taxes without appealing?
Yes. Exemptions, credits, and property record corrections can all reduce your taxes without going through the formal appeal process. Start with exemptions, then consider an appeal if your assessed value is still too high.
What is the deadline to appeal property taxes in Delaware?
The appeal deadline is within 30 days of assessment notice. Check with your county for the exact date, as some deadlines vary by locality.
Do I need professional help to lower my property taxes?
Most homeowners can handle exemption applications and basic appeals on their own. For complex situations or high-value properties, professional assistance may be worth the cost. PropertyTaxFight provides the data and guidance you need for $79, without hiring an attorney or consultant.
