Does Iowa Tax Retirement Income?

No. Iowa does not tax Social Security benefits.

Social Security benefits are not taxed by Iowa at any age or income level.

The Iowa answer is separate from the federal one. Depending on combined income, up to 85% of Social Security benefits can be taxable on the federal return regardless of what Iowa does, so the state rule changes the state line only. Our guide to states that do not tax Social Security shows where Iowa sits among the states that still tax benefits.

Iowa's treatment of pension income: Exempt at 55+.

Public and private pension income, including IPERS and defined-benefit plans, is excluded once the recipient is 55 or older on December 31 of the tax year. Nonqualified deferred compensation and nonqualified annuities do not qualify.

The exclusion is unlimited in dollars and has no income cap. Eligibility turns on being 55 or older on the last day of the tax year, being disabled, or being a surviving spouse or survivor with an insurable interest in someone who would have qualified. A 54-year-old taking the same distribution pays 3.8% on it.

Public and private pensions, annuities, and retirement-plan distributions do not always get the same treatment. The pension comparison lists which states exempt pensions broadly, partly, or only for certain plans.

Iowa's treatment of traditional 401(k) and IRA withdrawals: Exempt at 55+.

Distributions from traditional and Roth IRAs, 401(k), 403(b), SEP and SIMPLE IRAs, Keogh plans, and 457(b) deferred-compensation plans are excluded for taxpayers 55 or older, with no dollar cap.

Two timing points matter in Iowa. A Roth conversion is taxable in the year it is done, and Iowa starts from federal adjusted gross income, so a large conversion can land in a year when the state exclusion does not cover it. Qualified Roth withdrawals later are generally not taxable at either level. Required minimum distributions follow the same Iowa rules as any other traditional-account withdrawal.

Every state page on this site runs the same retiree profile so the states can be compared: $30,000 of Social Security, $40,000 withdrawn from a traditional 401(k), and a $20,000 private pension, $90,000 in total.

A 68-year-old with $30,000 of Social Security, $40,000 from a 401(k), and a $20,000 pension excludes all $90,000 from Iowa income. The Iowa tax on this retirement income is zero.

Step one, Social Security is not Iowa income at any age. Step two, the retiree is 68, so the $40,000 of 401(k) distributions and the $20,000 pension are subtracted in full as retirement income. Step three, Iowa taxable income from these sources is zero, and the 3.8% rate never applies. Contrast a $150,000 lump-sum IRA withdrawal at 68: it is also excluded, so Iowa tax stays at zero and the only cost is federal. Now contrast a 52-year-old taking the same $60,000 from a 401(k) and pension: none of it is excluded, so after the standard deduction roughly $45,000 is taxed at 3.8%, about $1,700 of Iowa tax that disappears once the taxpayer is 55 on December 31.

The same $90,000 profile looks different a state line away. The rows below come from the reviewed 51-state table; each state name links to its own guide.

• Illinois: treats Social Security as exempt, pensions as exempt, and 401(k) and IRA withdrawals as exempt, with a top rate of 4.95% and qualified retirement income is subtracted.
• Missouri: treats Social Security as exempt, pensions as partially taxed, and 401(k) and IRA withdrawals as partially taxed, with a top rate of 4.70% and public-pension deduction and phased $6,000 private exemption.
• Nebraska: treats Social Security as exempt, pensions as taxed, and 401(k) and IRA withdrawals as taxed, with a top rate of 4.55% and military retirement pay is exempt.

The age line, not the type of income, is what catches people. Someone who retires at 52 and starts drawing a pension pays Iowa tax on it for three years, then pays nothing, and nonqualified annuities and deferred compensation never qualify no matter how old the recipient is.

Military retirement: Military retirement pay is excluded from Iowa income regardless of age. See the military retirement tax map for every state's treatment.

Estate and inheritance tax: Iowa repealed its inheritance tax for deaths on or after January 1, 2025, and has no estate tax.

Selling a home or investments in Iowa: retirement-income rules do not cover capital gains. See Iowa capital gains tax before selling appreciated property or a brokerage position in the year you move or retire.

• Confirm the exclusion you are claiming. The exclusion is unlimited in dollars and has no income cap. Eligibility turns on being 55 or older on the last day of the tax year, being disabled, or being a surviving spouse or survivor with an insurable interest in someone who would have qualified. A 54-year-old taking the same distribution pays 3.8% on it.
• Part-year residents. If you moved into or out of Iowa during the year, retirement income is generally allocated to the period of residency, and the former state may still tax distributions received before the move. Document the move date, the new domicile, and where each distribution was received.
• Withholding and estimates. Pension and IRA custodians often withhold federal tax but not Iowa tax. If Iowa taxes any part of your retirement income, check whether quarterly estimated payments are needed to avoid an underpayment penalty.
• Federal side. The federal return has its own rules: up to 85% of Social Security can be taxable, the temporary $6,000 federal senior deduction is available for 2025 through 2028 subject to income limits, and Roth conversions are taxed in the conversion year. State exemptions do not change any of that.
• Large one-time distributions. For an early retiree, time large distributions for the year you turn 55, because eligibility is measured on December 31. Under 55, live on taxable brokerage assets or Roth basis and let qualified plan distributions wait for the exclusion.
