Iowa has slashed its income tax from a top rate of 8.53% (as recently as 2022) to a flat 3.8% — one of the most dramatic state income tax cuts in modern US history. All retirement income is fully exempt from Iowa income tax since 2023. The estate tax was eliminated in 2022. Property tax is moderately above average at ~1.33%. Sales tax is a straightforward 7% (6% state + 1% local) 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 moved to a flat 4.82%; and 2025 brought the rate to a flat 3.8% — a reduction of over 4.7 percentage points in just three years.
Equally significant: Iowa made all retirement income fully exempt from state income tax effective 2023. Pensions, Social Security, IRA distributions, 401(k) withdrawals, and military retirement are all now untaxed in Iowa. The state also eliminated its estate tax effective January 1, 2022, and phased out its inheritance tax. 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%. At the top bracket, Iowa’s income tax rate was among the highest in the Midwest and competitive even with some coastal states. A high-income Iowan was paying nearly the same percentage in state income tax as someone in California (which tops out at 13.3%) on a relative basis.
The Multi-Year Phase-Down
Governor Reynolds’ 2022 tax reform bill set a legislated schedule for rate reductions:
2022: Graduated brackets with top rate 8.53%
2023: Brackets consolidated; top rate 6.0%
2024: Flat rate 4.82%
2025: Flat rate 3.8%
Future: Further reductions toward a target rate of approximately 3.5% are under active legislative discussion
The driving argument for the cuts: Iowa was losing residents — particularly retirees and high-income households — to nearby states with no or low income taxes, particularly South Dakota (no income tax) and Florida. The reform aimed to arrest that outflow and attract new residents and businesses.
How Iowa’s Flat Tax Works Today
For 2025 and 2026, Iowa taxes all income above the standard deduction at a flat 3.8%. Iowa uses federal adjusted gross income (AGI) as the starting point, with Iowa-specific modifications. Iowa couples the flat tax with a standard deduction based on federal amounts. One notable Iowa provision: Iowa allows a deduction for federal income taxes paid on the Iowa return (partially, and subject to limitation), which can modestly reduce Iowa taxable income for some filers.

Section 02
Iowa’s Full Retirement Income Exemption: A Game-Changer for Retirees
What Changed in 2023
Effective January 1, 2023, Iowa made all retirement income exempt from state income tax for residents who are 55 years of age or older. Prior to 2023, Iowa taxed most retirement income — including Social Security, pension distributions, and IRA/401(k) withdrawals — as ordinary income. 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: Fully exempt
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 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 is $0. Under the pre-2023 system with the old 8.53% top rate, that same couple could have owed thousands of dollars in state income tax.
Iowa’s Transformation as a Retirement Destination
Prior to 2022, Iowa was routinely ranked among the less tax-friendly states for retirees. 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 the Eliminated Estate 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 1.1%, and comparable to Wisconsin's rate — though still lower than Illinois's, and higher than Minnesota's or South Dakota's. 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.
Sample Iowa Property Tax Estimates
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 tax credit of approximately $145–200/year for all Iowa homeowners on their primary residence (must apply through the county assessor)
Elderly and Disabled Credit: Low-income homeowners aged 65+ or disabled may qualify for a credit of up to $1,000/year against property taxes paid, depending on income
Military Exemption: Veterans with qualifying service receive a $1,852 reduction in assessed value on their primary home
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 mandatory 1% local option sales tax in most counties (which has been adopted by virtually all Iowa counties), resulting in a uniform 7% rate across nearly all of Iowa. There are no additional city-level sales tax additions beyond this 1% local option.
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. Iowa has expanded its sales tax to cover certain digital services and software-as-a-service in recent years as part of efforts to modernize its tax base.
Estate Tax and Inheritance Tax: Both Gone
Iowa eliminated its state estate tax effective January 1, 2022. Prior to this, Iowa had a separate state estate tax for larger estates. There is no Iowa estate tax for deaths occurring on or after January 1, 2022.
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. This is one of the most dramatic state income tax reductions in recent US history — Iowa’s top rate was 8.53% as recently as 2022. The rate was reduced to 6% in 2023, 4.82% in 2024, and 3.8% in 2025. Further reductions toward approximately 3.5% are under legislative consideration.
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. 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 eliminated its estate tax effective January 1, 2022. Iowa also phased out its inheritance tax, which reached 0% effective 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 1.1%, and roughly on par with Wisconsin, though below Illinois. In Des Moines (Polk County), a $250,000 home typically generates an annual property tax bill of approximately $3,500–4,000. Iowa offers a Homestead Credit of approximately $145–200/year 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 has been adopted by virtually all Iowa counties. Unlike many states, there are no additional city-level sales tax additions, making Iowa’s sales tax one of the more predictable and simple systems in the country. Unprepared groceries and prescription drugs are exempt from Iowa sales tax.
Q
Is Iowa becoming more attractive for retirees?
Yes, significantly so. Iowa was routinely ranked as unfavorable for retirees when its top income tax rate was 8.53% and retirement income was taxable. The combination of the full retirement income exemption (effective 2023), the flat 3.8% income tax rate, and the elimination of the estate and inheritance taxes has transformed Iowa’s standing. 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 one of the largest and fastest income tax reductions of any US state in modern history in terms of rate magnitude. States like North Carolina and Georgia have reduced rates significantly, but Iowa’s absolute reduction of over 4.7 percentage points from a high starting point is exceptional. The full retirement income exemption added in 2023 reinforces that Iowa has fundamentally repositioned its tax competitiveness, especially for the retirement-age population.
