Bottom line: Delaware is easier on many retirees than some states. It does not tax Social Security, and people age 60 or older can usually exclude up to $12,500 each of eligible retirement income on the Delaware return. But property-tax relief is a different story: it is local, not automatic, and many seniors miss savings because county, school, and city programs use different rules and deadlines.

What senior taxes in Delaware actually look like

Do not start with the Delaware return until your federal return is done. The resident instructions tell taxpayers to complete the federal return first because Delaware starts from federal adjusted gross income, also called adjusted gross income (AGI).

For most older adults in Delaware, there are really two different tax questions. One is the state income-tax question: How does Delaware treat Social Security, pensions, individual retirement account (IRA) withdrawals, 401(k) withdrawals, annuities, interest, and capital gains? The other is the local property-tax question: What help is available from the state, county, school-tax system, city, or town?

That split matters because the calendars are different. Delaware income-tax filing in spring 2026 usually means filing a 2025 return by April 30, 2026. Property-tax programs often run on county fiscal years that start July 1, and some deadlines are in April while others are in June or later.

Delaware is friendly to many retirees in a few important ways. The state says Social Security is not taxable. Delaware also says there are no state or local sales taxes. But that does not mean retirees can ignore taxes. Delaware still has a personal income tax, with graduated rates under $60,000 and a top 6.60% rate above that level, and local property-tax bills can be the bigger financial problem for seniors on fixed income.

Quick facts

Who this page is for

  • Retirees living in Delaware full time
  • Older adults thinking about moving to Delaware
  • Low-income seniors trying to reduce a tax or property-tax bill
  • Homeowners and renters who are confused about what Delaware actually offers
  • Caregivers and adult children helping a parent organize tax papers or call an office
If you need help with Best place to start What to ask
Delaware state return, refund, or 1099-R issue Division of Revenue Public Service or the state filing page “Do I need to file, how is this retirement income treated, and where is my refund?”
Senior school-tax credit State Senior School Property Tax Relief through your county office “Do I meet the age, domicile, and payment-current rules, and what is my deadline?”
County or city property-tax break New Castle County, Kent County, Sussex County, or Wilmington “Which program fits my age, income, and residency, and what documents do you need?”
Free tax preparation AARP Foundation Tax-Aide or IRS Volunteer Income Tax Assistance and Tax Counseling for the Elderly “Can you handle Delaware returns with pensions or IRA withdrawals, and what should I bring?”
Town or city senior discount The official Delaware cities and towns directory “Does my town have its own senior property-tax or utility discount on top of county relief?”

Does Delaware tax Social Security?

No. Delaware says in both its personal income-tax frequently asked questions and its resident instructions that Social Security benefits are not taxable in Delaware. The same rule applies to Railroad Retirement benefits.

That is good news for older adults whose income is mostly Social Security. But do not stop there. If you also have pension income, IRA withdrawals, dividends, interest, capital gains, wages, or rental income, you may still need to file. Delaware’s filing thresholds increase with age, which helps some seniors, but they do not erase the filing requirement for everyone.

Simple Delaware filing-threshold examples for 2025 returns Under 60 Age 60 to 64 Age 65 or older, or blind Age 65 or older and blind
Single or head of household $9,400 $12,200 $14,700 $17,200
Married filing joint $15,450 $17,950 $20,450 $22,950

These numbers come from the 2025 resident instructions. If you file married separate, combined separate, or are claimed as someone else’s dependent, use the official instructions to check your exact threshold.

Does Delaware tax retirement income?

Usually yes, but not all of it. Delaware starts with the amount of pension, IRA, 401(k), and other retirement-plan income that is taxable on your federal return. Then Delaware lets many seniors subtract some or all of that income through its retirement-income exclusion rules.

The biggest rule is this: if you were 60 or older on December 31, 2025, Delaware generally allows an exclusion of up to $12,500 per person for your combined pension and other “eligible retirement income.” That is a combined bucket, not a separate exclusion for every income type.

Income type How Delaware treats it for many seniors What to watch for
Social Security Not taxable Do not include it in Delaware taxable income.
Pensions Taxable if federally taxable, but age 60+ may exclude up to $12,500 per person Under age 60, the exclusion is much smaller for most people.
IRA withdrawals Taxable if federally taxable; age 60+ can use the same combined exclusion Do not assume IRA money gets a separate extra deduction.
401(k), 457, and similar plan withdrawals Taxable if federally taxable; age 60+ can use the same combined exclusion If withholding is too low, you can still owe Delaware tax in April.
Interest, dividends, capital gains, and net rental income These can count toward the same $12,500 age-60-plus cap This is often missed. It is still one combined per-person limit.
Annuities or other 1099-R income Usually follows federal taxability, then Delaware exclusion rules may apply If you are unsure whether it came from a qualifying retirement plan, ask a preparer or the state help line.
Early withdrawals Do not qualify for the pension exclusion if the 1099-R shows code 1 or you paid the federal early-withdrawal penalty This is one of the most common mistakes.
Military pension before age 60 The resident instructions give military retirees under 60 a special exclusion up to $12,500 That is better than the usual under-60 rule.

Example: If both spouses are 67 and one spouse has an $8,000 pension while the other takes a $6,000 IRA withdrawal, each spouse calculates their own exclusion. If they also share $4,000 of joint interest and dividends, each spouse may count half of that toward their own exclusion. One spouse does not get to use the other spouse’s unused amount.

Delaware also says in its retirement frequently asked questions that the top state rate is 6.60%, so retirees who want state tax withheld from pension or IRA payments usually do not need more than that withheld. If you take large withdrawals without enough withholding, consider asking about Delaware withholding or using the state’s estimated-tax forms.

Senior tax breaks, deductions, and rules that matter most

The most valuable Delaware breaks for seniors are real, but they are easy to misunderstand.

  • Social Security and Railroad Retirement are not taxed: confirmed in the resident instructions.
  • Age 60+ retirement-income exclusion: usually up to $12,500 per person.
  • Under-60 rule: the state says the usual under-60 pension exclusion is limited to $2,000, while military retirees under 60 have a better rule in the resident instructions.
  • Extra Delaware standard deduction for age 65+ or blindness: the state allows an additional $2,500 per qualifying person, but only if you use the Delaware standard deduction. If you itemize, you do not get this extra amount.
  • No state or local sales tax: Delaware says this plainly on its tax information page. That helps everyday budgets, even though it is not a filing credit.

What seniors in Delaware miss most often

  • The $12,500 is one combined bucket per person. It is not $12,500 for pension plus another $12,500 for IRA plus another $12,500 for interest.
  • Recent movers can be surprised. You can be a Delaware resident for income-tax filing and still not qualify yet for the senior school-tax credit because of the state domicile rule.
  • Property-tax relief is not automatic. County and city programs often need a separate application even if your Delaware return is already filed.
  • Paper returns can be slow. Delaware says e-file refunds may come in as little as 10 days if no extra review is needed, but paper returns and manually reviewed returns average 12 weeks.

Property-tax relief overview

If you own your home, check both the state school-tax credit and your county or city program. In Delaware, one application does not cover every possible break. If your main problem is the bill on your home rather than your income-tax return, use our deeper Delaware property-tax relief coverage after you read this overview.

The broad statewide program is the Senior School Property Tax Relief credit. It gives homeowners age 65 or older a credit against regular school property taxes of 50% up to $500 on a primary residence. The state says taxes must be paid in full by the end of the tax year to qualify for the next year’s credit, the deadline is April 30, and a Delaware driver’s license or state identification card is required. The state also says that for people who first established Delaware legal domicile on or after January 1, 2018, the wait is generally 10 consecutive years before eligibility.

Once you qualify for the statewide school-tax credit, the state frequently asked questions say you generally do not need to reapply every year unless you move. If only one spouse is 65, the state says that spouse can still apply if the couple owns the property together in the usual married way, but only one credit per property can be granted in a year.

Where you live Relief to check first Key facts Best next step
Statewide Senior School Property Tax Relief Age 65+, primary residence, 50% of regular school tax up to $500, April 30 deadline, domicile rule for newer residents, taxes must be current Call your county office listed on the state relief page.
New Castle County Over-65 exemption and the county’s separate school-tax exemption rules 2026 form shows up to $173,000 assessed-value reduction for county tax, household income cap of $65,000 for the county exemption, lower income caps for the separate school-tax exemption, June 1 deadline, and a 10-year Delaware domicile rule Call the Office of Assessment at 1-302-395-5520.
Kent County Elderly/Disability Property Tax Exemption Annual application; age 65 by May 31 or qualifying disability; 1 year in the home; 5 years as a Delaware resident; income caps of $18,000 single or $24,750 married, excluding Social Security; county page describes a taxable-assessment reduction but does not post one simple statewide-style dollar cap Call the Tax Office at 1-302-744-2341 or Assessment at 1-302-744-2401.
Sussex County Over-65 Exemption and Property Tax Subsidy Over-65 exemption requires age 65 by June 30, 5 years of county residency, and income other than Social Security under $6,000 single or $7,500 married; exemption applies up to $229,000 of assessed value. The separate subsidy applies only to the county portion and uses different income and asset limits. Call Sussex Billing at 1-302-855-7871.
City of Wilmington City property-tax exemption Applies to the first $210,300 of assessed valuation for qualifying homeowners age 65+, with income caps and a water/sewer discount; April 30 deadline. Wilmington also has a Senior Property Tax Assistance Program with grants up to $3,000 for older homeowners facing foreclosure because of delinquent city taxes or sewer/water bills. Call City Finance at 1-302-576-2400 or Delaware State Housing Authority at 1-302-577-5001 for the assistance program.

Local variation matters a lot in Delaware. New Castle, Kent, and Sussex do not use the same income limits, deadlines, or residency rules for their local senior programs. Cities and towns may also add their own rules. If you live inside town or city limits, use the official Delaware local-government directory and ask whether there is an extra senior exemption, discount, or utility break where you live.

Rent rebate or circuit-breaker overview

Do not wait for a broad statewide renter tax rebate in Delaware. As of April 2026, the official Delaware state and county tax-relief pages reviewed for this guide focus on homeowners, school-tax credits, and local property-tax exemptions. They do not show a broad statewide senior rent-rebate or circuit-breaker cash program like the programs some people know from neighboring states.

If you rent in Delaware, that means your best next step is usually housing-cost help, not the tax office. Start with the Delaware State Housing Authority, the Division of Social Services emergency assistance page, or your local housing authority if rent is the real problem. If you are looking for more detail on what Delaware does and does not offer here, use our Delaware rent-rebate and circuit-breaker coverage.

Free tax help in Delaware

You do not always need to pay a tax preparer. Delaware and federal partners offer several lower-cost or no-cost ways to get help.

  • Delaware online filing: the state’s file-online page says Delaware offers free online filing with no income requirements.
  • AARP Foundation Tax-Aide: use the Tax-Aide locator or call 1-888-227-7669. The Delaware AARP page says sites may be in senior centers, libraries, and other local locations.
  • Volunteer Income Tax Assistance and Tax Counseling for the Elderly: the Internal Revenue Service says these programs help people who generally make $69,000 or less, persons with disabilities, limited-English taxpayers, and adults age 60 or older. Call 1-800-906-9887.
  • Revenue offices in all three counties: the Division of Revenue office page lists public-service offices in Wilmington, Dover, and Georgetown, plus the toll-free number 1-800-292-7826.
  • Paper forms and library access: Delaware says on its paper forms page that forms are no longer sent to post offices and stores, but many public libraries have forms available for photocopying. You can also call 1-302-577-8209 to have forms mailed.

If an adult child or caregiver is helping with a parent’s tax matter, Delaware also posts Form ATH-RTF, Authorization to Release Tax Information. If you are handling a final return after a death, Delaware lists Form PIT-CFR, Claim for Refund of Deceased Taxpayer on its forms page.

What to gather before filing or asking for help

  • ☐ Your federal return, or a rough draft of it
  • ☐ Last year’s federal and Delaware returns, if you have them
  • ☐ All Forms 1099-R for pensions, annuities, IRAs, and 401(k) withdrawals
  • ☐ Your Social Security Benefit Statement, Form SSA-1099
  • ☐ Any Forms 1099-INT, 1099-DIV, 1099-B, W-2, or 1099-NEC
  • ☐ Your current property-tax bill and parcel number if you are asking about home-tax relief
  • ☐ Delaware driver’s license or state identification card
  • ☐ The date you became legally domiciled in Delaware and, if different, the date you moved into the current home
  • ☐ Bank routing and account numbers if you want direct deposit
  • ☐ Power of attorney or Delaware authorization form if you are helping a parent

What to do first without wasting time

  • Sort the problem: is this a Delaware income-tax issue, a local property-tax issue, or both?
  • Do the federal return first: Delaware starts with federal adjusted gross income.
  • List income by type: Social Security, pension, IRA or 401(k), investment income, work income, and rental income.
  • Check whether you even need to file: use the age-based Delaware filing thresholds in the resident instructions.
  • If home taxes are the stress point, call the county before you assume you are out of options.
  • Book free help early: AARP and Internal Revenue Service volunteer sites fill up quickly near deadlines.
  • If you owe and cannot pay in full, file or extend on time anyway: Delaware says there is no extension of time to pay, only extra time to file.

Most useful phone scripts

State tax department

“Hi, I’m helping my parent with a Delaware return. Their income is Social Security plus a 1099-R. Can you tell me whether they still need to file and which retirement exclusion applies?”

County assessor or tax office

“Hi, I’m 67 and my property-tax bill is getting hard to manage. Which senior credit or exemption should I check first, what is the deadline, and what documents do you need from me?”

Free filing-help site

“Hi, do you prepare Delaware state returns for retirees with pension and IRA income? What should I bring, and do you have appointments by phone, in person, or both?”

City or town finance office

“Hi, I live inside city or town limits. Does my municipality offer any senior property-tax or utility discount on top of county or state programs?”

Reality checks

  • Refunds can still take time: Delaware says e-file refunds may be as fast as 10 days if no extra review is needed, but paper or manually reviewed returns average 12 weeks.
  • One missed deadline can cost real money: the state school-tax credit usually uses an April 30 deadline, while some county programs use different dates.
  • Recent movers often get surprised: Delaware may welcome you as a resident for income-tax filing right away, but the state senior school-tax credit still has a long domicile rule for many newer residents.
  • Local relief is not uniform: New Castle, Kent, Sussex, Wilmington, and some towns all use different income rules, residency tests, and benefit amounts.

Common mistakes to avoid

  • Thinking Delaware taxes Social Security when it does not
  • Forgetting that interest, dividends, capital gains, and net rental income can count toward the age-60-plus retirement exclusion cap
  • Claiming the extra age-65 Delaware deduction while itemizing deductions
  • Assuming one property-tax application covers state, county, school, and city relief
  • Missing the April 30 or June 1 deadline because you thought all tax deadlines were the same
  • Filing before all 1099-R forms arrive
  • Ignoring Delaware withholding or estimated tax after a large IRA withdrawal

Best options by need

  • If your income is mostly Social Security: check whether you need to file at all, then shift your attention to property-tax relief if you own your home.
  • If your income is pension or IRA-heavy: use the retirement exclusion carefully and review Delaware withholding on future withdrawals.
  • If you just moved to Delaware: do not assume you qualify right away for the state senior school-tax credit.
  • If you are a low-income homeowner: county and city exemptions may save more money than anything you do on the income-tax return.
  • If you are a renter on fixed income: start with housing-cost help, not a tax-rebate search.
  • If you are helping a parent: gather permission paperwork early and use a free preparer if the return is simple.

What to do if overwhelmed or stuck

  • Stop and sort the papers into three piles: state income tax, property tax, and “other.”
  • Ask one narrow question at a time: “Do I need to file?” is easier to answer than “Can you fix everything?”
  • Use the right office: the Division of Revenue handles the state return; county offices handle most home-tax relief; city finance offices handle city programs.
  • Ask for the exact document list before you go: this prevents repeat trips.
  • If you missed a deadline: ask whether there is a future-year application, a payment plan, or a factual-error correction route for assessments. For example, New Castle County’s 2026 presentation says factual-error corrections can be requested at any time.
  • If you cannot use the internet easily: call the toll-free state line, ask for mailed forms, or use a public library.

Local resources

Diverse communities

Low-income seniors

Low-income older adults in Delaware often get more value from county exemptions, Sussex subsidy rules, or Wilmington city relief than from state income-tax planning alone. Free filing help through IRS volunteer programs can also reduce mistakes.

Veteran seniors

Veterans should ask about the special military retirement exclusion for some people under age 60 and the disabled veteran school-tax credit. In New Castle County, the county’s 2026 presentation also describes a separate county disabled-veteran exemption.

Rural seniors with limited access

If travel is hard, use the state’s toll-free line, ask for mailed paper forms, or use a local library. Sussex County also posts direct tax phone numbers for current taxes, delinquent taxes, and exemptions.

Seniors with disabilities

Delaware’s resident instructions say an authorized agent, guardian, or fiduciary may file if the taxpayer cannot do so. County disability exemptions are also available in New Castle, Kent, and Sussex.

Immigrant and refugee seniors

The Internal Revenue Service says Volunteer Income Tax Assistance sites help limited-English taxpayers. When you call, ask what language help is available before you travel to the site.

Frequently asked questions

Does Delaware tax Social Security for seniors?

No. Delaware says in its retirement frequently asked questions and its resident instructions that Social Security benefits are not taxable. The same is true for Railroad Retirement benefits. That makes Delaware easier on many retirees, but you may still need to file if you have other taxable income.

Does Delaware tax pensions, IRA withdrawals, and 401(k) withdrawals?

Yes, if they are taxable on your federal return, but Delaware then applies its own exclusion rules. For many people age 60 or older, Delaware allows up to $12,500 per person of combined pension and eligible retirement income to be excluded. That same bucket can also include interest, dividends, capital gains, and some net rental income, which is a rule many people miss.

I moved to Delaware recently. Can I get the senior school-tax credit right away?

Maybe not. The state’s Senior School Property Tax Relief page says people who established Delaware legal domicile on or after January 1, 2018 generally need 10 consecutive years of Delaware domicile before they qualify. That is one of the most misunderstood Delaware senior tax rules.

What if only one spouse is 65?

The state’s program frequently asked questions say that if a married couple owns the home together in the usual married way, the spouse who is 65 or older can apply even if the other spouse is younger. But only one full credit may be granted for the property in a year.

Does Delaware have a renter rebate or circuit-breaker program for senior renters?

As of April 2026, the official Delaware state and county tax-relief pages reviewed for this guide did not show a broad statewide senior renter rebate or circuit-breaker cash program. Delaware’s official tax-relief pages are focused mostly on homeowners, school-tax credits, and local property-tax exemptions. If you rent and need help, start with the Delaware State Housing Authority or the Division of Social Services emergency assistance page.

Which property-tax program should I check first in New Castle, Kent, or Sussex County?

Every senior homeowner should first check the state senior school-tax credit. After that, local rules matter. New Castle has separate over-65 county and school-tax exemptions with a June 1 deadline on the 2026 county form. Kent uses an annual elderly/disability application. Sussex posts both an over-65 exemption and a separate property-tax subsidy.

I help my parent with taxes. What should I bring, and do I need permission paperwork?

Bring the federal return, all 1099-R forms, the Social Security statement, last year’s return, the current property-tax bill, and identification. If you need to speak with Delaware about a parent’s tax matter, look at Form ATH-RTF, Authorization to Release Tax Information. If you are handling a return after a death, Delaware lists Form PIT-CFR for refund claims involving a deceased taxpayer.

I still work part-time in Maryland or another state. Can Delaware tax the same income twice?

Delaware residents may be able to claim a credit for taxes paid to another state on the same income. Delaware explains this on its personal income-tax frequently asked questions. If this applies to you, gather the other state return before you do Delaware, because the credit usually requires that paperwork.

Resumen en español

Para muchos adultos mayores, Delaware es un estado relativamente favorable porque no cobra impuesto estatal sobre el Seguro Social. Además, muchas personas de 60 años o más pueden excluir hasta $12,500 por persona de ciertos ingresos de jubilación en la declaración estatal. Pero la ayuda con los impuestos sobre la propiedad es más complicada, porque depende mucho del condado, la ciudad y las fechas límite locales.

Si necesita ayuda rápida, comience con la División de Ingresos de Delaware para preguntas sobre la declaración estatal, o con la página oficial del crédito escolar para personas mayores si el problema es el impuesto de la casa. Para ayuda gratuita con la preparación de impuestos, puede usar AARP Foundation Tax-Aide o los programas gratuitos del Servicio de Impuestos Internos. Si usted alquila y busca una “rent rebate,” tenga cuidado: en las páginas oficiales revisadas para esta guía no aparece un programa amplio estatal para inquilinos mayores, así que puede ser mejor empezar con la Autoridad de Vivienda del Estado de Delaware o con la asistencia de emergencia del estado.
