As of 2023, Iowa stopped taxing retirement income altogether for anyone 55 or older.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance This is a recent and sweeping change: pensions, IPERS, IRA, 401(k), 403(b), 457(b), SEP, SIMPLE, and annuity income are all fully exempt for qualifying retirees, and Social Security was already untaxed. Layer on Iowa's new flat 3.8 percent rate, and a state that used to tax retirement income now barely touches it for most seniors. The Iowa retirement income tax has become one of the most retiree-friendly in the country, which is a genuine reversal worth understanding in full.
This guide breaks down how Social Security, pensions, IRA and 401(k) income, and the broad senior exemption each work after Iowa's recent overhaul.

Iowa Retirement Income Tax at a Glance
Iowa's rules became dramatically simpler in 2023. Social Security is out. Nearly every other kind of retirement income is out too, as long as you are 55 or older. What little remains taxable is taxed at a single flat rate. The table below lays out each source.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance
| Income type | Treatment | Limit or amount | Who qualifies |
|---|---|---|---|
| Social Security | Fully exempt | 100% of benefits | All retirees |
| Pension and IPERS | Fully exempt | 100% | Age 55+ (also disabled, certain survivors) |
| IRA and 401(k) income | Fully exempt | 100% | Age 55+ (also disabled, certain survivors) |
| 403(b), 457(b), SEP, SIMPLE, annuities | Fully exempt | 100% | Age 55+ (also disabled, certain survivors) |
| Senior-specific exclusion | The 55+ exemption covers retirement income broadly | 100% | Age 55+ |
Iowa moved to a flat individual income tax of 3.8 percent for all income beginning with tax year 2025.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance For qualifying retirees, very little retirement income reaches that rate at all.
Iowa Retirement Income Tax: How It Works
Iowa overhauled its treatment of retirement income, and the result is unusually clean. The Iowa Department of Revenue confirms that beginning with tax year 2023, retirement income is exempt for taxpayers who are 55 or older, as well as for the disabled and certain surviving spouses.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance Social Security was already untaxed, and the flat 3.8 percent rate adopted for 2025 simplifies whatever is left.
The breadth of the exemption is the headline. There is no dollar cap and no income test. It is a full exclusion of qualifying retirement income.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance The main gates are age (55 and older) and the type of income, which spans virtually every common retirement vehicle. For most Iowa retirees, that combination means the state tax on their pension and account income drops to zero.
Social Security
Iowa does not tax Social Security benefits.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance There is no income test and no phase-out, so every Iowa retiree keeps the full amount of their benefits regardless of other income.
This was true before the broader overhaul and remains true now. Combined with the 55-and-older exemption on other retirement income, it means a typical retiree living on Social Security plus a pension or IRA owes the state nothing on that income.
The 55-and-Older Exemption
The centerpiece of the 2023 change is a full exemption of retirement income for taxpayers 55 and older.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance The exemption also reaches the disabled and certain surviving spouses, so it is not limited strictly to those who hit the age threshold.
What counts as retirement income here is broad: pensions and IPERS, IRA, SEP, SIMPLE, 401(k), 403(b), 457(b), and annuity income.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance IPERS is the Iowa Public Employees' Retirement System, the pension that covers Iowa's teachers, state employees, and most local government workers, so a large share of the state's retirees draw their pension through it. Because there is no dollar cap, the size of your pension or account balance does not erode the benefit the way a fixed exemption would in other states. A retiree with a large IPERS pension and a retiree with a modest one are treated the same: both exempt.
One gate matters. The full exclusion is for taxpayers 55 and older (plus the disabled and certain surviving spouses). If you are under 55 and not disabled, your retirement income distributions remain taxable at Iowa's flat 3.8 percent rate.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance
Pensions, IRAs, and 401(k)s
Under the old rules, Iowa taxed most of this income with only limited exclusions. Under the current rules, pensions, IPERS, IRA withdrawals, and 401(k), 403(b), and 457(b) distributions are all fully exempt for qualifying taxpayers.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance The same applies to SEP and SIMPLE accounts and to annuity income.
For retirees who built their savings in private accounts rather than a government pension, this is the most meaningful part of the change. In many states, IRA and 401(k) income is exactly what gets taxed; in Iowa, it is now exempt for the 55-and-older group. The practical effect is that a retiree can draw down a 401(k) to cover living costs or care without owing Iowa income tax on those withdrawals.
If you are weighing how much to draw from these accounts to cover care, retirement accounts for care walks through the tradeoffs.
Putting It Together
The practical takeaway is that Iowa flipped from a state that taxed retirement income to one that largely does not. For a qualifying retiree, Social Security, pension, IPERS, IRA, and 401(k) income can all be exempt, leaving little or nothing for the flat 3.8 percent rate to touch. For someone on a fixed income, that shift can mean hundreds of dollars a year that stay in their pocket rather than going to the state.
Picture a single retiree, age 60, with $24,000 in Social Security and $45,000 drawn from a traditional 401(k). Under the current rules, the Social Security is exempt and the entire $45,000 401(k) withdrawal is exempt because the retiree is 55 or older, so Iowa income tax on this retirement income is zero.Iowa Department of Revenue. (n.d.). Retirement Income Tax Guidance. revenue.iowa.gov. Retrieved Jun 24, 2026, from https://revenue.iowa.gov/taxes/tax-guidance/individual-income-tax/retirement-income-tax-guidance Under Iowa's pre-2023 rules, a large share of that $45,000 would have been taxable. The figures here are hypothetical and shown only to illustrate how the 55-and-older exemption works; they are not a real case and not a prediction of your own outcome.
This is general information rather than personalized tax advice, and whether your specific income type and filing situation qualify under the 55-and-older rule is exactly the kind of detail worth confirming with the Iowa Department of Revenue or a tax professional before you plan withdrawals. If retirement savings are part of how you will fund care, building a senior care funding plan is a useful next step.
