Delaware County DE Homestead Exemption: Rules, Senior School Tax Credit & Savings
Delaware does not have a county named “Delaware County.” The state has three county jurisdictions for property-tax filing: New Castle County, Kent County and Sussex County. So if you searched “Delaware County homestead exemption,” the practical question is usually: which Delaware property-tax credit or exemption can reduce my bill, and which county office receives the application?
This guide explains the real Delaware homeowner relief programs: the Senior School Property Tax Credit, the Disabled Veterans School Tax Credit, county-level elderly/disability exemptions where available, assessment appeals, and the correct county offices for filing.
Does Delaware Have a Homestead Exemption?
Delaware does not use a single statewide “homestead exemption” program like Texas or Florida. Instead, homeowners usually look for a school property-tax credit, a county senior/disability exemption, a disabled-veteran school tax credit, or an assessment appeal. The application is usually filed with the county property-tax or assessment office where the home is located.
Senior School Property Tax Credit
Homeowners age 65 or older may qualify for a credit against regular school property taxes on a primary residence. The credit is 50% of eligible regular school tax, up to $500.
Deadline: April 30 for the upcoming tax year.
Disabled Veterans School Tax Credit
A qualifying veteran with 100% VA disability compensation due to service-connected permanent and total disability, including individual unemployability, may qualify for a 100% non-vocational school property-tax credit.
Cannot combine: This credit cannot be claimed with the senior school credit for the same year.
County Exemptions and Assessments
New Castle, Kent and Sussex have local assessment and tax offices. County programs may include disability, elderly, nonprofit, farmland or other exemptions depending on county law and documentation.
Start with: the county where the property is physically located.
Delaware Homestead-Style Property Tax Relief Programs Compared
Delaware homeowner tax relief is easier to understand when you separate school credits, county exemptions and assessment appeals. They solve different problems.

|---|---|---|---|---|
| General Delaware homestead exemption | Delaware does not have one universal homeowner homestead exemption application for all owner-occupied homes. | Not available as a single statewide program. | No general deadline because this specific program does not exist. | Use the actual senior, veteran, disability, county or appeal program instead. |

How to Apply for Delaware Senior, Veteran or County Property Tax Relief
Use this workflow before downloading a form. It prevents the most common mistake: filing with the wrong county or requesting a program that does not match the homeowner’s status.
Identify the Correct County
First confirm whether the property is in New Castle, Kent or Sussex County. Postal city names do not always explain the correct county filing office.
Choose the Actual Relief Program
Choose senior school tax credit if the homeowner is 65 or older. Choose disabled-veteran school tax credit if the homeowner meets the VA disability rule. Choose county exemption if your county has a local senior, disability, nonprofit, farmland or other program.
Confirm Primary Residence and Domicile Rules
Delaware senior and disabled-veteran school credits are for a primary residence. New senior applicants who became legally domiciled in Delaware on or after January 1, 2018 generally need 10 consecutive years of Delaware domicile for the senior school credit.
Gather ID and Proof Documents
Senior credit applicants should include a valid driver’s license or official state ID for each applicant. Disabled-veteran credit applicants should include valid ID, VA disability documentation and a copy of the Social Security card as required by Delaware Department of Finance guidance.
File With the County by April 30 When Applicable
Senior school credit and disabled-veteran school credit applications for the upcoming tax year are due April 30. County elderly/disability exemptions may also use April 30, but you should verify the exact local form and filing rule before relying on any deadline.
Check the Tax Bill After Approval
The senior school credit is deducted from the property-tax bill before the county mails the bill. If the credit or exemption is missing, contact the county office that administers the program before assuming the school district or state has made an error.
Documents Delaware Homeowners Should Prepare
The correct document set depends on the program. Do not upload or mail a generic “homestead” form until you know whether you are applying for senior school credit, disabled-veteran school credit, local county exemption or assessment correction.
| Situation | Likely Form / Proof | Where to File | Common Mistake |
|---|---|---|---|
| Age 65+ senior school credit | Senior School Property Tax Credit application, valid driver’s license or official state ID for each applicant. | County property-tax or assessment office where the home is located. | Missing April 30 or assuming the credit applies without an application. |
| Senior applicant moved to Delaware after 2017 | Proof supporting 10 consecutive years of legal Delaware domicile. | County office receiving the senior credit application. | Confusing seasonal residence with legal domicile. |
| Disabled veteran school credit | Disabled Veterans School Property Tax Credit application, valid ID, VA disability proof and Social Security card copy. | County where the principal residence is located. | Trying to claim both disabled-veteran school credit and senior school credit in the same year. |
| Kent County elderly/disability exemption | Kent County elderly/disability property-tax exemption application and income/supporting documents. | Kent County Assessment Office. | Forgetting that Kent County requires annual re-application for certain local exemption records. |
| Property owned by trust | Trust or ownership documentation showing the applicant’s qualifying relationship to the property. | County assessment office. | Assuming a trust-owned property qualifies without county review. |
| Assessment seems incorrect | County appeal form, comparable property evidence, factual correction evidence, photos, measurements or other proof. | County assessment appeal office or Board of Assessment Review. | Filing a senior credit application when the real problem is an incorrect assessment. |
