Iowa retirement taxes in 2026: what retirees pay

Iowa is a friendly state for retirees. Social Security isn't taxed here at all, and once you reach the qualifying age shown below, Iowa also leaves pension income and withdrawals from retirement accounts alone. Iowa does have an income tax, charged at a single flat rate. For many retirees, though, most of the money they live on falls outside it. This page shows which kinds of income Iowa taxes and which it doesn't, so you can see where your own income fits.

What three retirees would pay in Iowa

These are estimates from Monte Climb's planner on 2026 law, for three example households. They start, as the app does, from federal taxable income: the 2026 standard deduction plus the extra amount at 65 3, the taxable part of Social Security 4 and the senior deduction 5. Those federal deductions are already taken off, and most states allow less of their own, so Iowa's real bill can be higher than shown.

• A single retiree, 67 with $54,000 of income would owe about $0 to Iowa, after $30,000 of retirement income is excluded and $11,300 of taxable Social Security is left out.
• A married couple, both 67 with $106,000 of income would owe about $0 to Iowa, after $60,000 of retirement income is excluded and $35,700 of taxable Social Security is left out.
• A married couple, both 62, before Social Security with $76,000 of income would owe about $0 to Iowa, after $70,000 of retirement income is excluded.

Every figure here starts from federal taxable income, as above, so a state whose own deductions are smaller can tax more than shown.

What these estimates leave out

• Iowa's own standard deduction, exemptions and credits: the estimate starts from federal taxable income instead, which takes off the larger federal deductions.
• City income taxes, and capital gains rules a state applies apart from its rate.
• Rules for military and public-employee pensions that some states treat separately.

What this means for your plan

If most of your income will come from Social Security, a pension or retirement-account withdrawals, Iowa may tax very little of it once you're past the qualifying age. Timing still matters. Withdrawals taken before that age, and income from other sources like wages, are where Iowa's flat rate can still apply. Monte Climb runs Iowa's rules on your own plan, including when each income source starts, so you can see how the state's treatment fits your timeline.
