Iowa cut its income tax from a top rate of 8.53% in 2022 to a flat 3.8% from 2025. Since 2023, retirement income is excluded for residents aged 55 or older, disabled residents, and surviving spouses, and Social Security is not taxed. Iowa has no estate tax, and its inheritance tax was repealed for deaths on or after 1 January 2025. Property tax averages about 1.33% of home value. Sales tax is 7% (6% state + 1% local option) in most areas.

Introduction
Iowa has undergone a tax transformation unlike almost any other state in the country over the past five years. In 2022, Iowa’s top marginal income tax rate stood at 8.53% — one of the highest flat or near-flat rates in the Midwest. Governor Kim Reynolds signed sweeping tax reform legislation that initiated a multi-year phase-down: 2023 saw the top rate drop to 6%; 2024 used three brackets with a top rate of 5.7%; and 2025 brought a flat 3.8% under a 2024 law that accelerated the schedule — a top-rate reduction of over 4.7 percentage points in three years.
Equally significant: from 2023 Iowa excludes retirement income from state income tax for residents aged 55 or older, disabled residents, and qualifying surviving spouses. Pensions, Social Security, IRA distributions, 401(k) withdrawals, and military retirement are all now untaxed in Iowa. Iowa has no state estate tax (its estate tax applied only to deaths before 2005 and the statutes were repealed in 2014), and its inheritance tax was repealed for deaths on or after January 1, 2025. For retirees, Iowa has pivoted from one of the most burdensome states to one of the most attractive in the region. This guide explains what changed, what’s current for 2026, and what Iowa’s overall tax picture means for workers and retirees.
Section 01
Iowa Income Tax: From 8.53% to 3.8% — The Story of the Decade
Where Iowa Started
To understand how dramatic Iowa’s tax transformation is, consider the starting point. In 2022, Iowa had nine income tax brackets with rates from 0.33% to 8.53%.
The Multi-Year Phase-Down
Governor Reynolds’ 2022 tax reform bill set a legislated schedule for rate reductions, which a 2024 law (SF 2442) accelerated to a flat 3.8% in 2025:
2022: Graduated brackets with top rate 8.53%
2023: Brackets consolidated; top rate 6.0%
2024: Three brackets, top rate 5.7%
2025: Flat rate 3.8%
2026: Flat rate 3.8% (unchanged)
Supporters argued the cuts would help Iowa keep and attract residents and businesses, including retirees and high-income households, relative to states with no or low income taxes.
How Iowa’s Flat Tax Works Today
For 2025 and 2026, Iowa taxes all income above the standard deduction at a flat 3.8%. Since 2023, Iowa starts from federal taxable income, so the federal standard deduction ($16,100 for a single filer in 2026) applies. Iowa’s former deduction for federal income taxes paid no longer applies for 2026, and a $40 personal exemption credit (single filer) is applied against the tax.

Section 02
Iowa’s Full Retirement Income Exemption: A Game-Changer for Retirees
What Changed in 2023
Effective January 1, 2023, Iowa made retirement income exempt from state income tax for residents who are 55 or older, disabled, or the qualifying surviving spouse of someone who qualified. Prior to 2023, Iowa taxed most pension and IRA/401(k) distributions as ordinary income, although Social Security benefits were already not taxed. The change was part of the same 2022 tax reform package that initiated the income tax rate reductions.
What’s Now Fully Exempt
The following retirement income sources are completely exempt from Iowa income tax for qualifying residents (age 55+):
Social Security benefits: Not taxed by Iowa (at any age)
Pension income: All pension distributions, including Iowa Public Employees’ Retirement System (IPERS), city and county pensions, and private defined benefit pensions
IRA distributions: Traditional IRA, Roth IRA, SEP-IRA, SIMPLE IRA
401(k) and 403(b) distributions: Fully exempt
Military retirement pay: Fully exempt
Annuity income: Qualifying annuity distributions exempt
For a retired Iowa couple (both 55 or older) receiving $30,000 in Social Security, $40,000 in pension income, and $20,000 in IRA distributions — a combined $90,000 in retirement income — the Iowa income tax bill on that income is $0. Under the pre-2023 system, that same couple could have owed state income tax on the $60,000 of pension and IRA income.
Iowa’s Transformation as a Retirement Destination
With the combination of the retirement income exemption and the flat 3.8% rate on non-retirement income, Iowa has pivoted dramatically. The state now competes meaningfully with Wisconsin (which taxes most retirement income) and Minnesota (top rate 9.85%, retirement income largely taxable) for residents who want to remain in the upper Midwest without facing heavy state income taxes on their retirement savings withdrawals.
Section 03
Iowa Property Tax, Sales Tax, and Estate and Inheritance Tax
Property Tax: Above-Average Burden
Iowa’s effective property tax rate of approximately 1.33% of market value is above the national average of about 0.90%, nearly the same as Wisconsin's (1.32%), lower than Illinois's (1.88%), and higher than Minnesota's or South Dakota's (1.00% each) (Tax Foundation, 2024 Census data). Property taxes in Iowa are administered at the county level and fund local governments and school districts. Iowa assesses property at 100% of market value for residential properties. Rates vary by county and city.
Illustrative Iowa Property Tax Estimates (approximate, not official figures)
Des Moines (Polk County, $250,000 home): approximately $3,500–4,000/year
Cedar Rapids (Linn County, $220,000 home): approximately $3,200–3,600/year
Iowa City (Johnson County, $280,000 home): approximately $4,200–4,800/year (university area, higher school millage)
Sioux City (Woodbury County, $180,000 home): approximately $2,600–3,000/year
Property Tax Credits and Exemptions
Iowa offers several property tax relief programs:
Homestead Credit: A credit equal to the levy rate times the first $4,850 of actual value of a primary residence (must apply through the county assessor)
Elderly and Disabled Credit: Low-income homeowners aged 65+ or disabled may qualify for an income-based credit against property taxes paid (limits are set by the Iowa Department of Revenue)
Military Exemption: Qualifying veterans receive a reduction of up to $4,000 in taxable value (assessment year 2023 and later)
Sales Tax: Simple and Predictable at 7%
Iowa’s sales tax is among the more straightforward systems in the country: 6% state rate plus a 1% local option sales tax that most, but not all, Iowa cities and counties have adopted, giving a combined 7% in most places and 6% in some. The local option is capped at 1%.
Iowa exempts groceries (unprepared food) from sales tax — a meaningful relief for families. Prescription drugs are also exempt. Prepared food from restaurants is taxed at the standard 7% rate.
Estate Tax and Inheritance Tax: Both Gone
Iowa has no state estate tax. Its former estate tax applied only to deaths before January 1, 2005, and the underlying statutes were repealed in 2014.
Iowa had an inheritance tax that applied to non-immediate-family heirs. The 2021 tax reform legislation phased this out over several years, reducing rates each year until the tax reached 0% effective January 1, 2025. Iowa no longer has an inheritance tax. For all practical purposes, Iowa is now a no-estate-tax, no-inheritance-tax state — a significant improvement for families with meaningful assets to transfer.

Iowa’s income tax rate is a flat 3.8% for 2026. Iowa’s top rate was 8.53% as recently as 2022. The top rate was reduced to 6% in 2023 and 5.7% in 2024, and the rate became a flat 3.8% in 2025.
Q
Is retirement income taxed in Iowa?
No. Iowa made all retirement income fully exempt from state income tax effective January 1, 2023, for residents aged 55 and older, disabled residents, and qualifying surviving spouses. This includes Social Security benefits, pension income (including IPERS and private pensions), IRA distributions, 401(k) and 403(b) withdrawals, military retirement pay, and qualifying annuities. A retired Iowan with income solely from these sources pays $0 in Iowa state income tax.
Q
Does Iowa have an estate tax?
No. Iowa has no estate tax (its former estate tax applied only to deaths before 2005). Iowa also phased out its inheritance tax, which was repealed for deaths on or after January 1, 2025. Iowa is now a no-estate-tax, no-inheritance-tax state. Federal estate tax may still apply for very large estates exceeding the federal exemption threshold, but Iowa imposes no additional state-level tax.
Q
What is the property tax rate in Des Moines?
Iowa has moderately above-average property taxes, with an effective statewide average rate of approximately 1.33% of market value — above the national average of about 0.90%, and roughly on par with Wisconsin, though below Illinois. Our rough illustrative estimate for a $250,000 home in Des Moines (Polk County) is $3,500–4,000 a year; check your county’s levy rates. Iowa offers a Homestead Credit (the levy rate applied to the first $4,850 of actual value) for primary residences, but this provides only modest relief against what are above-average property tax bills.
Q
What is Iowa’s sales tax rate?
Iowa’s sales tax is 7% in most areas — a 6% state rate plus a 1% local option sales tax that most, but not all, Iowa jurisdictions have adopted, so a few places charge only 6%. The local option cannot exceed 1%, which keeps Iowa’s sales tax relatively simple. Unprepared groceries and prescription drugs are exempt from Iowa sales tax.
Q
Is Iowa becoming more attractive for retirees?
Yes, from a tax standpoint. Before 2023 Iowa taxed most pension and IRA distributions, and its top income tax rate was 8.53% in 2022. The combination of the retirement income exclusion (effective 2023), the flat 3.8% income tax rate, and the end of the inheritance tax (2025) has improved Iowa’s tax position for retirees. The main remaining drawback is moderately above-average property taxes averaging ~1.33%, but for retirees with significant retirement account balances, the income tax benefits now outweigh this in many scenarios.
Q
How does Iowa’s tax reform compare to other states?
Iowa’s reduction from a top rate of 8.53% to a flat 3.8% in just three years is a drop of more than 4.7 percentage points in the top rate over three years. Other states, including North Carolina and Georgia, have also reduced rates significantly. The full retirement income exemption added in 2023 reinforces that Iowa has fundamentally repositioned its tax competitiveness, especially for the retirement-age population.
