Does Delaware Tax Social Security? (w/Examples) + FAQs

Currency note: This article reflects federal rules and Delaware rules as of June 2026 and covers tax year 2025 (the 2026 filing season). Tax law changes — confirm current figures with the Delaware Division of Revenue and IRS.gov before you file.

Quick Answer

No. Delaware does not tax Social Security benefits for tax year 2025. The state fully excludes Social Security and Railroad Retirement benefits from taxable income, no matter your age or how much you earn. You still report them on your federal return, but Delaware subtracts them out completely.

Delaware is one of the most tax-friendly states for retirees, and Social Security is the clearest example: every dollar of your benefit escapes state income tax. That matters because the average monthly Social Security retirement benefit reached about $2,008 in early 2025, or roughly $24,000 a year — income that a less friendly state could tax but Delaware leaves alone.

The catch is that “no tax on Social Security” does not mean “no tax in retirement.” Your pension, your 401(k) withdrawals, and your IRA distributions are a different story, and the rules there have real dollar consequences if you plan poorly or miss a deadline. This guide walks you through all of it.

The Short Version: Delaware and Social Security

Delaware treats Social Security the same way it treats Railroad Retirement benefits: as fully off-limits for state income tax. The Delaware Division of Revenue states plainly that “Social Security and Railroad Retirement benefits are not taxable in Delaware and should not be included in taxable income.”

This is a true, complete answer, and it does not change with your income level. Some states that do tax Social Security only tax it above an income threshold. Delaware has no such threshold because it does not tax the benefit at all. A retiree earning $30,000 and a retiree earning $300,000 both pay the same Delaware tax on Social Security: nothing.

The reason this works mechanically is that Delaware starts your state return from your federal adjusted gross income (AGI), then makes adjustments. Because some of your Social Security may be taxable at the federal level, that amount flows into your federal AGI. Delaware then subtracts it back out as a modification, so it never reaches your Delaware taxable income. The consequence of understanding this: if you forget the subtraction, you tax yourself, and the state will not refund money you never told them you overpaid unless you amend.

What you should do about it: confirm the Social Security subtraction is taken on your Delaware return every year, even if your software “should” do it automatically. One skipped line can cost you hundreds of dollars.

Federal First: Washington May Still Tax Your Social Security

Delaware leaves your Social Security alone, but the federal government might not. This is the single most confused point in retirement taxes, so separate the two clearly: the state answer is no, and the federal answer is “it depends on your income.”

At the federal level, the IRS uses a measure called combined income (your AGI, plus nontaxable interest, plus half your Social Security). The consequence of crossing certain combined-income lines is that part of your benefit becomes federally taxable.

For a single filer, up to 50% of benefits become taxable once combined income tops $25,000, and up to 85% once it tops $34,000.
For a married couple filing jointly, the same 50% and 85% tiers begin at $32,000 and $44,000.

A common misconception is that “85% taxable” means you lose 85% of your benefit. It does not. It means up to 85% of the dollar amount gets added to your taxable income and is then taxed at your ordinary rate — often a far smaller real hit.

What you should do about it: even though Delaware ignores your benefit, run the federal math, because the taxable portion still raises your federal AGI, which is where your Delaware return begins. Lowering federal taxable Social Security can indirectly shrink your Delaware bill too.

The 2025 Federal “Senior Deduction” (OBBBA)

A new federal break changes the federal picture for tax year 2025. The One Big Beautiful Bill Act created an extra senior deduction of up to $6,000 per person age 65 or older ($12,000 for a married couple where both qualify).

This deduction is temporary: it applies to tax years 2025 through 2028 and then sunsets unless Congress extends it. It is not a repeal of Social Security taxation, but for many seniors it wipes out the tax on the taxable portion of their benefits anyway by lowering taxable income.

The deduction phases out above a modified AGI of $75,000 (single) or $150,000 (married filing jointly), falling by 6 cents per dollar over the line and disappearing entirely at $175,000 / $250,000. Married-filing-separately seniors cannot claim it. What you should do: if you are 65+, make sure your 2025 federal return claims this deduction — it stacks on top of the regular standard deduction and the existing extra standard deduction for seniors.

Which Situation Applies to You?

Delaware’s answer on Social Security is the same for everyone, but your overall Delaware retirement tax depends on your facts. Find your row and read the matching section below.

You live on Social Security only. You almost certainly owe Delaware nothing. Skip ahead to Example 1.
You are 60 or older with a pension or 401(k). The $12,500 pension exclusion is your key tool — see the pension section and Example 2.
You are under 60 with retirement income. Your exclusion is capped at $2,000, so plan around the age-60 cliff.
You are a military retiree. A special rule may give you a larger exclusion even before age 60 — see the military section.
You are moving to Delaware soon. Read the property tax, sales tax, and inheritance sections, because those round out why retirees relocate here.

Delaware’s Pension and Retirement Income Exclusion

This is where “tax-friendly” gets nuanced. Delaware does tax pensions, 401(k) withdrawals, and IRA distributions to the extent they are taxable federally — but it gives older residents a generous exclusion that erases a large chunk of it.

For tax year 2025, a person age 60 or older can exclude up to $12,500 of eligible retirement income per person, as confirmed by the Delaware Division of Revenue. A person under age 60 can exclude only $2,000. The exclusion is per person, so a married couple where both spouses are 60+ can shelter up to $25,000 combined.

Eligible retirement income is broad. It includes pensions, distributions from IRAs, 401(k)s, and Keogh plans, government deferred-comp (Section 457) plans, plus dividends, interest, capital gains, and net rental income from real property. The consequence of the $12,500 cap is that high-income retirees still pay Delaware tax on retirement income above the exclusion — the break is meaningful but not unlimited.

A common misconception is that Social Security counts against this $12,500. It does not. Social Security is excluded separately and in full, so it never eats into your pension exclusion. What you should do: claim the exclusion on your Delaware return every year you qualify, and time large IRA withdrawals to make the most of it.

Heads-Up: The Proposed $25,000 Increase Is Not Law Yet

You may have read that Delaware raised the exclusion to $25,000. As of June 2026, that is a proposal, not law. House Bill 108 would double the exclusion from $12,500 to $25,000 for residents 60+ (and for military pensions under 60) starting in tax year 2025, but reporting in early 2026 confirms the bill was still pending in the General Assembly.

The consequence of treating the proposal as current law is real: if you exclude $25,000 on a 2025 return before the bill passes, you understate your tax and risk penalties and interest. What you should do: file using the $12,500 figure for tax year 2025, and watch the Delaware General Assembly site for final passage before relying on the higher number.

Military Pensions: A Bigger Break

Delaware gives military retirees an edge. Under current rules, a military pensioner can exclude up to $12,500 even if under age 60, instead of being held to the $2,000 under-60 cap that applies to civilians. This recognizes that many service members retire well before 60.

The consequence is a much lower Delaware bill for younger veterans living on a military pension. A common misconception is that the bigger break also covers a veteran’s civilian second-career pension; the exclusion still tops out at the per-person cap across eligible income. What you should do: if you are a military retiree under 60, claim the larger exclusion and keep your retirement-pay statement (1099-R) as proof.

Worked Examples: What Delaware Actually Charges

Numbers make this concrete. Delaware’s 2025 brackets run from 2.2% up to 6.6% on taxable income of $60,000 or more, with the first $2,000 untaxed, per the Delaware rate schedule. The 2025 standard deduction is $5,700 (single) / $11,400 (married filing jointly). Below are three representative retirees; figures are illustrative and rounded.

Example 1 — Margaret, age 68, Social Security only

Margaret is single and lives in Lewes on $26,000 a year, all Social Security. Delaware excludes 100% of her Social Security, so her Delaware taxable income is $0. Her Delaware income tax: $0. Even at the federal level, her income is low enough that little or none of her benefit is taxable, and the new senior deduction would erase any remainder.

Example 2 — Robert and Susan, both 65, Social Security + pension

This married couple lives in Dover with $40,000 Social Security and a $50,000 pension. Delaware drops the full $40,000 of Social Security. Each spouse claims the $12,500 exclusion, removing $25,000 of the pension. That leaves $25,000 of pension as Delaware income, minus the $11,400 standard deduction = about $13,600 taxable. Their Delaware tax lands near $450 — a fraction of what a high-tax state would charge.

Example 3 — David, age 58, early-retired with a 401(k)

David is single, retired early in Wilmington, and pulls $45,000 from his 401(k) plus $18,000 Social Security. Delaware excludes all $18,000 of Social Security. But because David is under 60, his retirement-income exclusion is only $2,000, not $12,500. So $43,000 of his 401(k) is Delaware income, minus the $5,700 standard deduction = about $37,300 taxable, for a Delaware tax near $1,750. Waiting until age 60 to tap the 401(k) would have unlocked the far larger exclusion.

Three Common Scenarios at a Glance

Each table below shows a situation and the Delaware result.

Scenario A — Retiree living on Social Security alone

Your Situation	Delaware Result
100% of income is Social Security	Fully excluded; Delaware taxable income is $0
Any age, any benefit amount	No Delaware tax on the benefit, ever
You forget to subtract it on the return	You overpay; must amend to recover

Scenario B — Retiree age 60+ with a pension

Your Situation	Delaware Result
Pension plus Social Security	Social Security fully excluded; up to $12,500 of pension excluded per person
Married, both 60+	Up to $25,000 combined retirement-income exclusion
Pension above the exclusion	Excess taxed at 2.2%–6.6%

Scenario C — Early retiree under age 60

Your Situation	Delaware Result
401(k) or IRA withdrawals before 60	Social Security still fully excluded
Retirement-income exclusion	Capped at $2,000, not $12,500
Military pensioner under 60	Larger $12,500 exclusion may apply

How Delaware Stacks Up Against Its Neighbors

Delaware’s no-tax-on-Social-Security stance is common nationwide, but its full retiree package stands out in the Mid-Atlantic. The table contrasts the core retirement-tax features for tax year 2025.

State	Retiree Tax Snapshot
Delaware	No Social Security tax; $12,500 pension exclusion (60+); no sales tax; no inheritance/estate tax
Pennsylvania	No tax on Social Security or retirement income for those past retirement age; 6% sales tax; has an inheritance tax
Maryland	No Social Security tax; pension exclusion available; 6% sales tax; has estate and inheritance taxes
New Jersey	No Social Security tax; generous retirement-income exclusion at lower incomes; 6.625% sales tax

Delaware’s edge is the combination: it pairs the Social Security exemption with no state or local sales tax — one of only a handful of states with none — and no estate or inheritance tax. Pennsylvania matches Delaware on income but still charges sales tax and an inheritance tax. What you should do: weigh the whole picture, not just one tax, when comparing states.

A Word on the No-Tax States

Florida, Texas, Tennessee, and several others levy no state income tax at all, so they tax neither Social Security nor pensions. Delaware cannot beat a zero income-tax state on income tax alone. But Delaware often competes well overall because those states typically rely on higher sales or property taxes, while Delaware has no sales tax and relatively low property taxes. What you should do: compare total tax burden, including property and sales tax, before assuming a no-income-tax state is cheaper.

Beyond Income Tax: Why Retirees Choose Delaware

Social Security is the headline, but three more features seal the deal for many retirees.

First, no sales tax. Delaware charges no state or local sales tax, which lowers the cost of everyday spending and big purchases alike. The consequence over a retirement is large: on $30,000 of annual taxable spending, a 6% sales tax elsewhere would cost about $1,800 a year that Delaware residents keep.

Second, low property taxes. Delaware’s effective property tax rates are among the lowest in the country, and seniors may qualify for additional school-property-tax credits. What you should do: contact your county assessor — [New Castle (302) 323-2600], Kent (302) 736-2077, or Sussex (302) 855-7760 — to ask about senior reductions.

Third, no estate or inheritance tax. Delaware repealed its estate tax, so heirs are not taxed by the state on what they inherit. This makes Delaware attractive for passing assets to family, though large estates may still face the federal estate tax.

Mistakes to Avoid

Each error below carries a real cost.

Including Social Security in Delaware taxable income. This inflates your tax and forces an amended return to recover the overpayment.
Treating the proposed $25,000 exclusion as current law. Using $25,000 for 2025 understates your tax and can trigger penalties of 5% per month plus interest.
Tapping a 401(k) at 58 instead of waiting until 60. You lose the $12,500 exclusion and keep only the $2,000 cap, as in Example 3 — a difference of thousands.
Forgetting the exclusion is per person. A married couple that claims only one $12,500 leaves up to $12,500 of shelter unused.
Assuming “no Social Security tax” means no federal tax. Up to 85% of your benefit can be federally taxable, which also raises your Delaware starting point.
Skipping the 2025 federal senior deduction. Eligible 65+ filers who miss the $6,000/$12,000 break overpay federal tax outright.
Over-withholding Delaware tax. Withholding more than 6.6% on distributions ties up cash you will only get back as a refund.
Counting out-of-state municipal bond interest as exempt. Only Delaware municipal bonds are state-tax-free; out-of-state bond interest is taxable to Delaware residents.

Do’s and Don’ts

Do confirm the Social Security subtraction on every Delaware return, because one missed line costs real money.
Do claim the $12,500 exclusion for each qualifying spouse, since it is per person.
Do wait until age 60 for big retirement withdrawals when possible, to unlock the larger exclusion.
Do keep your 1099-R and SSA-1099 forms, because you need them to support every exclusion.
Do check the General Assembly before relying on the proposed $25,000 figure, so you file on actual law.
Don’t include Social Security in Delaware taxable income, because it is fully exempt.
Don’t over-withhold above 6.6%, since that just lends the state money interest-free.
Don’t assume military and civilian pensions get separate full exclusions, because the per-person cap still applies.
Don’t ignore federal Social Security taxation, because it feeds your Delaware AGI.
Don’t treat a no-income-tax state as automatically cheaper, because sales and property taxes can erase the gap.

Pros and Cons of Delaware for Retirees

Pro: Social Security is 100% exempt, protecting your most reliable income stream.
Pro: No state or local sales tax saves money on every purchase, year after year.
Pro: No estate or inheritance tax helps you pass more to your heirs.
Pro: Low property taxes and senior credits cut a major housing cost.
Pro: A real pension exclusion shelters up to $25,000 for a qualifying couple.
Con: Pensions, IRAs, and 401(k) withdrawals above the exclusion are still taxed up to 6.6%.
Con: The under-60 exclusion is only $2,000, penalizing early retirees.
Con: The exclusion is capped, so high-income retirees still owe meaningful tax.
Con: No-income-tax states can beat Delaware on income tax alone.
Con: The promised $25,000 exclusion is not yet law, creating planning uncertainty.

What to Do Next

Take these steps in order to lock in the savings.

Gather your forms. Collect your SSA-1099 (Social Security), every 1099-R (pensions, IRAs, 401(k)s), and last year’s return before you start.
Run the federal return first. Determine how much Social Security is federally taxable and claim the 2025 senior deduction if you are 65+.
Start the Delaware return from federal AGI, then subtract 100% of Social Security and Railroad Retirement.
Apply the pension exclusion — $12,500 per person 60+, $2,000 if under 60 — using the correct figure for tax year 2025.
File the right form, generally the Delaware resident return (Form PIT-RES) by the April deadline, and keep copies.
Call a pro if your situation is complex — large IRA balances, a recent move, an estate, or a planned Roth conversion. A CPA or tax attorney can model the timing and usually saves more than the fee.

Frequently Asked Questions

Does Delaware tax Social Security benefits? No. For tax year 2025, Delaware fully excludes Social Security and Railroad Retirement benefits from taxable income at any age or income level. You report them federally, but Delaware subtracts them entirely from your state return.

Does Delaware tax 401(k) or IRA withdrawals? Yes. Delaware taxes 401(k) and IRA distributions to the extent they are taxable federally. But residents 60 or older can exclude up to $12,500 of eligible retirement income per person for tax year 2025.

How much retirement income can Delaware residents exclude? $12,500 per person age 60 or older for tax year 2025, or just $2,000 if under age 60. The exclusion is per person, so a qualifying married couple can shelter up to $25,000 combined.

Did Delaware raise the pension exclusion to $25,000? No, not yet. House Bill 108 proposes raising it from $12,500 to $25,000 starting in 2025, but as of June 2026 the bill was still pending. File using $12,500 for tax year 2025.

Does Delaware tax military retirement pay? Yes, but generously. Military pensions are taxable, yet a military retiree can claim the larger $12,500 exclusion even when under age 60, instead of the $2,000 cap that limits other early retirees.

What is Delaware’s income tax rate for retirees? 2.2% to 6.6% for tax year 2025. The first $2,000 of taxable income is untaxed, rates rise through the brackets, and the top 6.6% rate applies to taxable income of $60,000 or more.

Does Delaware have a sales tax? No. Delaware charges no state or local sales tax, one of only a handful of states with none. This lowers everyday and major-purchase costs and is a key reason retirees relocate there.

Does Delaware have an estate or inheritance tax? No. Delaware has no state estate tax and no inheritance tax, so heirs are not taxed by the state on what they inherit. Large estates may still owe federal estate tax.

Will I still owe federal tax on my Social Security in Delaware? Possibly. Up to 85% of your benefit can be federally taxable depending on your combined income, even though Delaware exempts it. The new 2025 federal senior deduction can offset much of that federal tax.

Which form do I use to claim the Social Security exclusion in Delaware? Form PIT-RES, the Delaware resident income tax return, for full-year residents. Start from federal AGI, subtract Social Security and Railroad Retirement, then apply your pension exclusion. File by the April deadline.

Is Delaware a good state to retire for taxes? Yes, for most retirees. It exempts Social Security, charges no sales tax, has low property taxes, and levies no estate or inheritance tax. The main drawback is that larger pensions and 401(k) withdrawals are still taxed.
