Retiring in Iowa: What the State Actually Takes

On the ordinary retirement profile — $34,000 of Social Security and $61,000 of plan distributions — Iowa takes $0 a year in state income tax.

That is the number people compare, and it is the smallest of three. Property tax adds about $3,275 on the state's $250,000 median home, and insurance another $3,765. The three together come to $7,040, placing Iowa 24th of 50.

A note before you start. This is general education, not tax advice. Every Iowa figure comes from this site's own fifty-state income-tax dataset and its retirement tax engine, computed for a single filer aged 70 unless stated otherwise; property tax, median home price and insurance figures come from the site's core state dataset. Rates are for tax year 2026. Property tax is assessed locally in most states, so the effective rate here is a statewide figure rather than your county's.

1. What Iowa takes from retirement income

On Social Security. Iowa does not tax Social Security benefits. Because Iowa's return begins from federal taxable income, any federally taxable portion of benefits arrives in the Iowa base and is removed by a subtraction on IA 1040 Schedule 1.

On 401(k) and IRA distributions. Fully exempt with no dollar cap, but only for a taxpayer who meets an eligibility condition, which is the part the headline lists routinely drop. Under Iowa Code section 422.7 as amended by House File 2317 (2022) and Senate File 181 (2023), and Iowa Administrative Code rule 701-302.47, the retirement income exclusion is available to a taxpayer who is 55 years of age or older on December 31 of the tax year, OR is disabled, OR is a surviving spouse or a survivor having an insurable interest in an individual who would have qualified. A separate branch covers a surviving spouse receiving a deceased spouse's pension from a protection occupation or as a sheriff, deputy sheriff, firefighter or police officer. For a married couple the test is per spouse: only the spouse who personally meets a condition may exclude their own retirement income, so a 57-year-old and a 52-year-old filing jointly do not both qualify. The scope is broad but not unlimited. Qualifying distributions include traditional IRAs (IRC 408(a)), Roth IRAs (408A) and Roth conversion income, SEP plans (408(k)), simple IRAs (408(p)), 401(k) plans, section 457(b) deferred compensation, defined benefit, pension and profit-sharing plans under IRC 401 including IPERS and ESOPs, Keogh plans, and section 414(x) combined plans.

2. The rule that decides your Iowa bill

Private and public pensions are exempt on the same terms as qualified plan distributions, through the same Iowa Code 422.7 retirement income exclusion, so both carry the age-55 / disabled / qualifying-survivor condition. Iowa is one of the few states where private and public pensions genuinely receive identical treatment, which is why all three entries read the same. Military retirement is the exception and is broader: it has its own standalone subtraction on IA 1040 Schedule 1 line 4, 'the amount of military retirement benefits received to the extent included in federal taxable income', with NO age condition, NO disability condition and no dollar cap. A 45-year-old Iowa military retiree excludes their pension in full while a 45-year-old with a private pension excludes nothing.

The single most consequential Iowa fact for a retirement calculator: a 54-year-old and a 55-year-old with identical 401(k) distributions face completely different Iowa tax. The exclusion is a cliff at age 55 on December 31, not a phase-in.

Iowa's exclusion has no dollar cap. That makes Iowa materially more generous than the capped-exclusion states it is often grouped with, where a large distribution exhausts the exclusion and the remainder is taxed.

3. What Iowa charges at three income levels

The same state, three retirements. All figures are for a single filer aged 70.

Read down the middle column. The exemption that makes a modest retirement free here is worth nothing to an affluent one — the bill goes from $0 to $908 as income rises. That is a phase-out, and it is the single most misreported feature of state retirement taxation.

A married couple with $48,000 of Social Security and $62,000 of distributions pays $0.

4. Property tax, and why it lands harder in retirement

An effective rate of 1.3% on the state's $250,000 median home is about $3,275 a year.

For a retiree this is a harder cost than income tax, and the reason is structural: property tax is levied on the house, while retirement income falls. A bill sized to a working income arrives every year after the income has gone.

It is also assessed locally almost everywhere, so a statewide effective rate conceals real variation between counties. Treat the figure above as the state's shape rather than as your bill.

Iowa does have a homestead provision, and it is the one lever on this line worth understanding.

Iowa converted its longstanding Homestead Tax Credit into a Homestead Tax Exemption effective assessment year 2026 (claimants who already had the credit before July 1, 2026 were automatically transitioned, no refiling required). The exemption reduces a homestead's taxable value by 10%, subject to a minimum exemption of $5,500 and a maximum of $20,000 in taxable value (the maximum begins adjusting annually for inflation starting January 1, 2027); an additional $6,500 taxable-value exemption is available for qualifying homeowners age 65+. The separate 100%-disabled-veteran homestead tax credit was not affected by this change and remains available. Iowa also has one of the broadest homestead exemptions in the country for creditor/judgment protection (unlimited dollar value on a qualifying homestead, subject to acreage limits — roughly 1/2 acre in a city plat or 40 acres in the country), a different, non-property-tax benefit under Iowa Code Chapter 561.

Two things about homestead rules catch people out after a move. They almost always require the property to be your primary residence, which a snowbird splitting the year has to be able to demonstrate. And several states require an application to the county rather than granting it automatically — a benefit you qualify for and never claimed is worth nothing.

5. Insurance, the line nobody prices

Average home insurance in Iowa: $3,765 a year — 40th cheapest of the fifty states.

This is the line almost no retirement comparison includes, and across the country it varies more than income tax does: from Hawaii's $900 to Florida's $8,375, a ninefold spread.

For a retiree it behaves like a second property tax. It rises independently of income, a fixed-income household absorbs the whole increase, and it is a condition of the mortgage if you still have one.

6. What retiring in Iowa actually costs

Income tax on the typical retirement profile, plus property tax and insurance on each state's own median home. Iowa is shown against its own neighbours in the ranking, and against the extremes.

Iowa comes to $7,040, 24th of 50.

Income tax is 0% of that total, which is the whole point: the number everybody checks contributes nothing to the number that matters.

One large caveat, and it matters. Each row uses that state's own median home, and those differ a great deal. So this compares the typical house in each state, not the same house in each state — buying below a state's median improves its figure materially.

7. The exemption shrinks as your income rises

Iowa's exemption is not a flat one. It shrinks as income rises, from $0 on a modest retirement income to $908 on an affluent one. Fully exempt with no dollar cap, but only for a taxpayer who meets an eligibility condition, which is the part the headline lists routinely drop. Under Iowa Code section 422.7 as amended by House File 2317 (2022) and Senate File 181 (2023), and Iowa Administrative Code rule 701-302.47, the retirement income exclusion is available to a taxpayer who is 55 years of age or older on December 31 of the tax year, OR is disabled, OR is a surviving spouse or a survivor having an insurable interest in an individual who would have qualified. A separate branch covers a surviving spouse receiving a deceased spouse's pension from a protection occupation or as a sheriff, deputy sheriff, firefighter or police officer. For a married couple the test is per spouse: only the spouse who personally meets a condition may exclude their own retirement income, so a 57-year-old and a 52-year-old filing jointly do not both qualify. The scope is broad but not unlimited. Qualifying distributions include traditional IRAs (IRC 408(a)), Roth IRAs (408A) and Roth conversion income, SEP plans (408(k)), simple IRAs (408(p)), 401(k) plans, section 457(b) deferred compensation, defined benefit, pension and profit-sharing plans under IRC 401 including IPERS and ESOPs, Keogh plans, and section 414(x) combined plans. A phase-out is a marginal rate in disguise. Inside the phase-out band an extra dollar of income costs the ordinary rate plus the exemption it withdraws — so the real cost of a larger withdrawal is higher than the headline schedule suggests.

8. What a Roth conversion costs in Iowa

A conversion of $100,000 costs $0 in Iowa state tax, even though Iowa has an income tax.

That is because the state exempts retirement plan distributions outright, and a Roth conversion is a distribution. There is no ceiling at which the exemption stops in the range tested here.

The federal tax is unchanged and still due, along with the IRMAA consequence two years later. The state's share is what disappears.

9. What part-time work costs here

Here is the asymmetry that defines Iowa for a retiree: $100,000 of plan distributions costs $0, and $20,000 of part-time work costs $148.

The state exempts retirement income and taxes wages. So the marginal cost of another dollar of 401(k) money is nothing, and the marginal cost of another dollar earned is 0.7%.

That inverts the usual advice. The conventional counsel is to work a little longer and preserve the balance. In this state the arithmetic points the other way — drawing on the pre-tax balance is the cheaper source of the next dollar, by a wide margin.

10. The order to draw your accounts in

The order you draw accounts in is worth real money, and the right order depends on the state.

Draw the pre-tax balance first, which is the opposite of the usual advice. In Iowa the state cost of a plan distribution is zero and the state cost of earned income is 0.7%, so the pre-tax account is the cheapest dollar available.

Roth money is worth less here than elsewhere, because the thing a Roth protects against — state tax on the withdrawal — does not exist in this state. It still protects against federal tax, and against a future move to a state that does tax distributions.

Required minimum distributions overrule all of this from 73 onward. Once they begin you must take the calculated amount whether the order suits you or not, which is the argument for drawing down or converting the pre-tax balance in the years before.

11. Or move across the state line

For most people the real alternative to Iowa is not Wyoming — it is the state on the other side of the line, near the same family, the same doctors and the same weather.

South Dakota is the cheapest of the group at $6,351, $689 below Iowa. Whether that is worth a move is a question about your life rather than your spreadsheet — but it is the comparison worth running, because it is the one you could actually act on.

One thing this table cannot show is the county. Property tax is set locally, and the spread inside a single state is routinely wider than the gap between two neighbouring states. A border move to a cheaper state and an expensive county can leave you worse off.

12. If you are moving to Iowa from somewhere else

The eight most populous states people leave, measured against Iowa on the same three lines.

Iowa is cheaper than 5 of these eight. Which means the answer genuinely depends on where you are starting from.

A move is not free, and this table does not price it. Transaction costs on both houses run to several per cent of the sale price, and at typical values that is often more than the first two or three years of the saving.

Iowa charges a transfer tax on the purchase itself — 0.2%, customarily paid by the seller. On the state's $250,000 median home that is about $400, once, at the point of sale. Closing costs here run about 2% to 5% of the price — $5,000 to $12,500 on the median home, which is the real entry fee for the annual saving this article has been describing.

13. What Iowa does not exempt you from

The federal system, entirely. This is the commonest misunderstanding about state retirement taxation, and it is worth stating plainly.

Required minimum distributions still apply. The amount is federal — your prior-year balance divided by an IRS life expectancy factor — and identical in all fifty states. A state changes what the distribution costs you, not whether you must take it.

Social Security is still federally taxable, on the federal provisional-income calculation, whatever your state does with it.

IRMAA still applies, with its two-year lag. A large conversion or distribution raises a Medicare premium two years later regardless of address.

And capital gains are still federally taxed. What Iowa adds on top is a separate question from what the federal system takes.

14. Establishing that you actually live here

Any state tax advantage is worth nothing until Iowa is your domicile, and the state you left may disagree about when that happened.

High-tax states audit departing residents. The question is not whether you own a home here; it is whether you genuinely abandoned the old domicile. Days spent in each state, voter registration, vehicle registration, where your doctors are and where you claim a homestead all bear on it.

The snowbird case is the risky one. Splitting the year between two states while keeping a home in both is exactly the profile a residency audit is built for. If a plan depends on the saving, count the days from the first year rather than reconstructing them afterwards.

15. Who Iowa actually suits

Someone on a modest retirement income. Iowa charges $0 at the modest profile — the exemption does its work at the bottom of the range.

It suits an affluent retiree least. At the affluent profile the bill is $908, and whatever exclusion helps a modest income has stopped helping by then.

It suits a homeowner less than a renter, because $3,765 of average insurance attaches to the property rather than to the income.

16. What to check before you decide

Get your county's actual property tax rate, not the state average. Property tax is levied locally almost everywhere, and the spread inside a state is often wider than the spread between states.

Get a real insurance quote on a real address. $3,765 is the state average; construction, roof age and exposure move it a long way.

Work out your own income tax rather than using the profile above. $95,000 split one way is not $95,000 split another, and in Iowa the mix between Social Security and distributions changes the answer.

And check what your current state actually charges you before assuming it is worse. On these three lines the ranking surprises people in both directions.

Frequently asked questions

Does Iowa tax Social Security? No. Iowa does not tax Social Security benefits. Because Iowa's return begins from federal taxable income, any federally taxable portion of benefits arrives in the Iowa base and is removed by a subtraction on IA 1040 Schedule 1.

Does Iowa tax 401(k) or IRA withdrawals? Fully exempt with no dollar cap, but only for a taxpayer who meets an eligibility condition, which is the part the headline lists routinely drop. Under Iowa Code section 422.7 as amended by House File 2317 (2022) and Senate File 181 (2023), and Iowa Administrative Code rule 701-302.47, the retirement income exclusion is available to a taxpayer who is 55 years of age or older on December 31 of the tax year, OR is disabled, OR is a surviving spouse or a survivor having an insurable interest in an individual who would have qualified.

For a married couple the test is per spouse: only the spouse who personally meets a condition may exclude their own retirement income, so a 57-year-old and a 52-year-old filing jointly do

What about pensions — private, government, or military? A $50,000 pension costs $0 if private, $0 if a government pension, and $0 if military retired pay.

What does retiring in Iowa actually cost? Income tax of $0 on the typical profile, plus about $3,275 of property tax and $3,765 of insurance on the median home — $7,040, which is 24th of 50.

Is Iowa a cheap state to retire in? On these three lines it ranks 24th of 50. Whether that makes it cheap for you depends far more on the house than on the tax code.

Does the exemption phase out? Yes. It is worth most at a modest income — $0 — and nothing by the affluent profile, where the bill is $908.

What does a Roth conversion cost in Iowa? An extra $0 in state tax on $50,000 converted, and $0 on $100,000. The federal tax on the conversion is unchanged and still due.

Does part-time work get taxed differently from my 401(k) withdrawals? Yes — and the gap is large. $20,000 of earnings costs $148 here while $100,000 of plan distributions costs $0, because Iowa exempts retirement income and taxes wages.

Would a neighbouring state be cheaper than Iowa? South Dakota is the cheapest of Iowa and its neighbours at $6,351 against Iowa's $7,040.

Do required minimum distributions change if I move here? No. The required amount is a federal calculation and identical in every state. What changes is what the distribution costs once taken.

Does this article include local income tax? Some Iowa municipalities levy their own income tax on top of the state figure above. This calculator does not include it.

Will Iowa's treatment still apply in ten years? State legislatures revise retirement taxation regularly — several states have changed theirs in the past three years. Figures here are for tax year 2026 and are worth re-checking before a move.
