Does Iowa Tax Retirement Income? Exclusions and Who Qualifies

Iowa does not tax most retirement income once you turn 55, and Social Security and military retirement pay are exempt regardless of age. Starting with the 2023 tax year, the state excludes distributions from IRAs, 401(k) plans, pensions, IPERS, and most other employer-sponsored retirement accounts from Iowa income tax if you’re 55 or older, disabled, or a qualifying survivor. Iowa’s flat income tax rate is 3.8% for 2026, but qualifying retirees owe nothing on their retirement distributions.¹

Who Qualifies for the Exclusion

The retirement income exclusion was enacted as part of House File 2317 in 2022 and applies to tax years beginning on or after January 1, 2023. You qualify if, by December 31 of the tax year, you meet any one of these conditions:²

You are 55 or older. There is no upper age limit.
You are disabled under Iowa’s definitions, at any age.
You are a surviving spouse of someone who qualified or would have qualified.
You are another qualifying survivor with an “insurable interest,” which Iowa limits to the son, daughter, mother, or father of the original account holder.

The survivor rule catches people off guard. If you inherit a retirement account from a parent or child who was 55 or older or disabled, the distributions you take are excluded. A sibling, niece, nephew, or friend who inherits the same account does not qualify under the survivor rule and would have to independently meet the age or disability test.²

Surviving spouses of law enforcement officers, firefighters, and sheriffs get broader treatment. If the deceased spouse’s pension came from one of these protection occupations, the surviving spouse can exclude the payments even if the deceased had not yet reached 55 or become disabled.²

Retirement Accounts That Are Exempt

The exclusion covers the account types most retirees actually hold:²

Traditional IRAs.
Roth IRAs, including income from Roth conversions.
401(k) plans and other qualified deferred compensation plans.
Defined benefit pensions, profit-sharing plans, stock bonus plans, and employee stock ownership plans.
457(b) deferred compensation plans, commonly offered by state and local governments.
IPERS (Iowa Public Employees’ Retirement System) benefits.
Qualified annuity distributions.

It doesn’t matter whether you take the money as monthly checks or a single lump sum. If the account qualifies and you meet the eligibility criteria, the distribution is excluded from Iowa taxable income.

Roth IRAs are on the list even though qualified Roth distributions are already tax-free federally. That matters mainly if you take a non-qualified Roth distribution that would otherwise be partially taxable.²

Retirement Income That Is Not Exempt

Two kinds of distributions fall outside the exclusion:²

Nonqualified deferred compensation plans under IRC Section 409A, which include supplemental executive retirement plans and similar arrangements that don’t meet ERISA qualification standards.
Nonqualified annuities, which typically show a distribution code of “D” in Box 7 of your Form 1099-R.

If you bought an annuity outside of an employer plan or IRA, it’s likely a nonqualified annuity and the distributions remain taxable at Iowa’s 3.8% rate, even if you’re over 55. The line between qualified and nonqualified isn’t always obvious from the account name, so check Box 7 on your 1099-R or ask your plan administrator.

Social Security Benefits

Iowa fully excludes Social Security from state income tax. This covers retirement, disability, and survivor benefits alike. Iowa Code Section 422.7 directs taxpayers to subtract all Social Security amounts that are taxable federally, which zeroes them out for Iowa purposes.³ No Social Security benefits have been taxable on the Iowa return since 2014.⁴

There is no income phaseout. Even if the federal government taxes up to 85% of your benefits based on combined income, Iowa ignores them entirely.

Military Retirement Pay

Military retirement pay has its own exclusion under Iowa Code Sections 422.7(31A) and 422.7(31B), and it is more generous in one key respect: there is no age or disability requirement. Military retirement pay is excluded from Iowa income tax whether you’re 40 or 80.⁵

The exclusion covers armed forces, armed forces reserves, and National Guard retirement pay, along with survivor benefits received under the Survivor Benefit Plan. It applies to both Iowa residents and nonresidents. Military retirement pay also isn’t counted when determining whether you meet the filing threshold for an Iowa return.⁵

If You’re Under 55 and Not Disabled

The retirement income exclusion does not apply to you if you’re under 55 and don’t qualify as disabled or an eligible survivor. Early retirees taking distributions in their late 40s or early 50s will owe Iowa income tax at the 3.8% flat rate for 2026.¹

When your plan administrator knows you don’t qualify, Iowa requires them to withhold state income tax from your distributions at 3.8%.⁶ The year you turn 55 is the first year you can claim the exclusion, as long as your birthday falls on or before December 31.

Moving To or From Iowa During Retirement

If you move into or out of Iowa mid-year, you file as a part-year resident. Pension, annuity, and IRA distributions received while you lived in Iowa count as Iowa-source income on Schedule IA 126.⁷ You still complete the full IA 1040, then use Schedule IA 126 to calculate a credit that limits the tax to Iowa-source income. The exclusion still applies to qualifying distributions you received during the Iowa-resident portion of the year if you meet the age, disability, or survivor rules. Distributions received after you moved away are not Iowa income.

How To File with Retirement Income

Gather every Form 1099-R from each account that paid you during the year before you start. Box 1 shows your gross distribution and Box 2a shows the federally taxable amount.⁸

On your IA 1040, retirement income adjustments flow through Schedule 1, which captures differences between federal and Iowa taxable income.⁹ Qualifying retirement income is subtracted from total income to arrive at Iowa net income. If all your income comes from exempt retirement sources and Social Security, your Iowa taxable income can be zero.

Estimated Tax Payments

If you have taxable income that isn’t subject to Iowa withholding and you expect to owe $1,000 or more in state tax, you’re required to make quarterly estimated payments.¹⁰ This typically affects retirees under 55 whose distributions aren’t adequately withheld, and retirees of any age with significant non-retirement income such as rental income or investment gains.

For 2026, the quarterly due dates are April 30, June 30, September 30, and January 31 of the following year.¹¹ If a due date falls on a weekend or holiday, it shifts to the next business day. Missing deadlines can trigger an underpayment penalty even if you pay the full amount with your return.

Most retirees over 55 whose income is entirely exempt retirement distributions and Social Security won’t need to make estimated payments. If you have a mix of exempt and taxable income, run the numbers early in the year.
