Understanding method 1: claim the senior school tax exemption starts with the basics. That is why understanding how to lower property taxes in delaware: every method available is worth your time.
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 Delaware assessments are notoriously outdated (some based on 1980s values), creating significant inequities.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 If your property is overvalued relative to others under this outdated system, an equity argument can be powerful.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With assessments based on decades-old data, property records may contain outdated or incorrect information about your home size, features, or condition.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.

The Delaware Appeal Process: Timeline and What to Expect
Understanding the full appeal timeline helps you plan ahead and avoid getting caught off guard. Here is how a typical Delaware property tax appeal plays out from start to finish.
Step 1: Receive Your Assessment Notice
Your county assessor mails your assessment notice, usually once a year. This document shows the assessed value of your property for the upcoming tax year. Read every detail on it. Check the property description, square footage, lot size, and any listed features. Errors here are more common than you might think, and they directly inflate your tax bill.
Step 2: File Your Appeal
In Delaware, appeals go to the county Board of Assessment Review. You will need to complete a formal petition or protest form. Most counties accept these online or in person. The form asks for your parcel number, current assessed value, the value you believe is correct, and a brief explanation of why. Keep the explanation factual. Stick to evidence, not opinions about whether your taxes are fair.
Step 3: Prepare Your Evidence Package
Between filing and your hearing date, assemble your case. The strongest evidence is comparable sales data showing similar homes sold for less than your assessed value. Supplement this with photos of your property's condition, documentation of any needed repairs, and your property record card with errors highlighted. Organize everything clearly so the review board can follow your argument in a few minutes.
Step 4: Attend Your Hearing
Most Delaware appeals begin with an informal review. This is a conversation, not a trial. Present your comparable sales first since that is what carries the most weight. Be prepared to answer questions about your property and your comparisons. Stay calm and stick to facts. If the informal review does not resolve your case, you may have the option to proceed to a formal hearing or a higher appeal body.
Step 5: Receive the Decision
After the hearing, the board issues a written decision. If they reduce your assessment, the reduction applies to your current tax year and typically carries forward until the next reassessment. If they deny your appeal, you usually have the right to escalate to a state-level board or court, though this adds time and complexity.
Key Deadlines for Delaware Homeowners
Missing a deadline in Delaware means waiting a full year for your next chance to appeal. That is another 12 months of overpaying. Here are the dates you need to know.
Assessment notice. When your notice arrives, your appeal clock starts. In most Delaware counties, you have 30 to 45 days from the notice date (not the date you received it) to file. Check the notice itself for the exact deadline.
Exemption applications. Most exemptions must be filed before the start of the tax year or within a specific window after you purchase your home. If you recently moved to Delaware or turned 65, check whether you qualify for exemptions you have not yet claimed. Late applications typically mean you lose the benefit for the entire year.
Payment due dates. Even if you are appealing, you generally still need to pay your tax bill on time. Failing to pay while appealing can result in penalties and interest. If your appeal succeeds, you receive a refund or credit for the overpayment.
Pro tip: Set a calendar reminder for 2 weeks before each deadline. That gives you time to gather documents and file without rushing.

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.
