Moving from Indiana to Iowa: Residency, Taxes, and What to Prove
Indiana's 2.95% (flat, state) + county income tax top income tax rate becomes 3.80% (flat) in Iowa. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
Indiana's statutory residency test uses a 183-day threshold. Iowa does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | Indiana | Iowa |
|---|---|---|
| Statutory Residency Test | Indiana Code 6-3-1-12 and 45 IAC 3.1-1-21 define a resident two independent ways: an individual domiciled in Indiana during the tax year, or an individual who is not domiciled in Indiana but maintains a permanent place of residence in the state and spends more than 183 days of the taxable year in Indiana. Indiana guidance explicitly notes the 183-day/permanent-residence test is a separate, independent basis for residency, not itself a test for domicile. | Iowa does not run a separate day-count statutory residency test layered on top of domicile the way New York, Missouri, or Nebraska do. Iowa Department of Revenue guidance treats domicile as the controlling test: an individual domiciled in Iowa for the tax year is an Iowa resident regardless of time spent physically present or absent, and Iowa administrative rules presume a person who maintains a permanent place of abode in Iowa and spends a substantial part of the year in the state is Iowa-domiciled absent clear evidence of a change. |
| Domicile Test | Under 45 IAC 3.1-1-22.5, Indiana presumes a person has not abandoned Indiana domicile if they maintained a permanent residence in Indiana and satisfy at least one of: claiming a homestead deduction or military tax exemption on an Indiana home, voting in Indiana, occupying an Indiana residence more days of the year than any other single state, claiming a federal tax benefit based on Indiana being the principal residence, or having a place of employment or business in Indiana. Supplementary factors include driver's license and vehicle registration location, dependent claims, mailing address, bank accounts, organizational memberships, and where professional services and valuables are located. | Iowa applies the standard facts-and-circumstances domicile factors under Iowa Administrative Code rule 701-38.17: permanent home, driver's license and vehicle registration, voter registration, location of family, employment, financial accounts, and stated intent. Iowa's guidance emphasizes that domicile, once established, continues until affirmatively changed by both the intent to abandon it and actual relocation; simply leaving Iowa temporarily does not end Iowa domicile. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | Indiana's statute uses 'more than 183 days,' which mirrors New York's and Illinois's phrasing; Indiana guidance does not publish a specific carve-out exempting partial days, and practitioners treat any day with meaningful Indiana presence as counting toward the total absent a documented exception like medical treatment or transit. | Not applicable. Iowa has no statutory day-count test, so there is no rule treating a partial day of physical presence as a full day for residency purposes. An Iowa domicile dispute turns on the totality of conduct and intent, not a day tally. |
| Presumptions | 45 IAC 3.1-1-22.5 creates a presumption against abandonment of Indiana domicile whenever a person kept a permanent Indiana residence and meets at least one of the five primary factors listed above (homestead claim, voting, most-days-in-state, federal filing benefit, or Indiana employment); this presumption is rebuttable but places real weight on continuing to hold any one of those Indiana connections. | None published |
| Safe Harbors | None published | None published |
Leaving Indiana
Indiana is not generally characterized by practitioners as an aggressive residency-audit state compared with its neighbors; its flat, comparatively low income tax rate reduces the dollar incentive for the Department of Revenue to pursue contested domicile cases the way high-rate states do. The Department does issue individual Letters of Findings resolving residency disputes, including cases finding a taxpayer was not subject to Indiana tax because they had established domicile in another state based on objective evidence like a home purchase and filings there, showing Indiana does examine claims on a case-by-case basis rather than running the kind of broad, headline exit-audit programs seen in New York or Minnesota.
Trailing Income
Indiana has no convenience-of-the-employer rule, so a former resident who works remotely from another state for an Indiana-based employer is generally not taxed by Indiana on those wages once genuinely nonresident, since Indiana sources employee compensation to where the work is physically performed. Indiana does continue to tax Indiana-source income after departure, including gain on Indiana real property and a departing resident's share of Indiana business income for the period they operated in the state.
Part-Year Filing
Form IT-40PNR, Indiana Part-Year and Full-Year Nonresident Individual Income Tax Return, is used for the year a taxpayer moves into or out of Indiana. It allocates income between the Indiana-resident portion of the year and the nonresident portion, and also handles the county income tax allocation based on county of residence or principal work location as of January 1 or as of the move date, depending on the specific county tax rule that applies.
Enforcement Methods
Common Exit Mistakes
Establishing Iowa Residency
| Action | Agency | Deadline |
|---|---|---|
| Title and register vehicles in Iowa | Iowa Department of Transportation, Motor Vehicle Division | within 30 days of becoming a resident, even if out-of-state plates are still valid |
| Obtain an Iowa driver's license | Iowa Department of Transportation | within 30 days of establishing residency |
| Register to vote | Iowa Secretary of State | at least 15 days before an election by mail or online; Iowa also allows Election Day registration in person with proof of identity and residency |
| File a Homestead Tax Credit and Exemption application | County Assessor | by July 1 of the year the credit is first claimed |
Declaration of Domicile
Iowa has no formal declaration-of-domicile filing comparable to Florida's county-recorded declaration. Iowa domicile is established through conduct: home purchase or lease, driver's license, vehicle titling, voter registration, and the pattern of actual presence and intent, with Iowa's rule that once domicile is established it continues until affirmatively abandoned.
Homestead
Iowa's Homestead Tax Credit and Exemption reduces the taxable value of an owner-occupied primary residence and is available to any qualifying homeowner, not just seniors or the disabled, which is broader than many neighboring states' age- or income-restricted programs. It must be filed once with the county assessor by July 1 of the first year claimed and then continues automatically as long as the homeowner still occupies the property as their primary residence, making it a persistent piece of domicile evidence that auditors check for a taxpayer claiming to have left Iowa.
Voter Registration
Register online or by mail at least 15 days before an election, or register and vote the same day in person at your county auditor's office or polling place with proof of identity and residency. https://sos.iowa.gov

New Resident Tax Traps
Iowa taxes worldwide income from the date Iowa residency begins, reported on the full-year IA 1040 or as a part-year filer using Form IA 126. New residents 55 or older should note that Iowa's full retirement-income exemption only applies once Iowa residency is established, so retirement distributions received before establishing Iowa domicile in the year of a move may need to be allocated between the prior state and Iowa depending on when the change actually occurred.
What Changes on Tax
Indiana Top Rate
2.95% (flat, state) + county income tax
Iowa Top Rate
3.80% (flat)
Moving from Indiana to Iowa raises the top marginal income tax rate from about 2.95% to about 3.8%, an increase of roughly 0.85 percentage points.
Withholding Reciprocity
Indiana and Iowa do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
Indiana and Iowa both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Indiana
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the flat state rate plus the applicable county rate.
Estate or inheritance tax: Indiana has no state estate tax and no inheritance tax; Indiana repealed its inheritance tax effective 2013. Only the federal estate tax, with its roughly $15 million per-person exemption in 2026, can apply to an Indiana decedent's estate.
Property tax: Indiana's average effective property tax rate is around 0.8% of home value, among the lower rates in the Midwest. The Homestead Standard Deduction reduces assessed value by the lesser of $48,000 or 60% of assessed value for an owner-occupied principal residence, with an additional supplemental deduction on the remaining value; county auditors are directed to develop procedures specifically to catch owners whose actual principal residence is outside Indiana.
Sales tax: Indiana has a flat statewide 7% sales tax, sometimes called the Gross Retail Tax, with no additional local sales tax layered on top anywhere in the state.
Iowa
Capital gains: Iowa taxes most capital gains as ordinary income at the flat 3.80% rate. Iowa retains a narrow capital gains exclusion for the sale of certain qualifying farmland and closely held business interests held long enough and meeting active-participation requirements, one of the more generous small-business and farm exclusions among flat-tax states.
Estate or inheritance tax: Iowa fully repealed its inheritance tax as of 2025, the final step of a phase-out enacted in 2021 (SF 619) that reduced rates by 20 percentage points each year from 2021 through 2024 before eliminating the tax entirely for deaths occurring on or after January 1, 2025. Iowa has no separate estate tax.
Property tax: Effective property tax rate on owner-occupied housing runs about 1.33%. Iowa's Homestead Tax Credit and Exemption reduces taxable value on an owner-occupied primary residence for any qualifying homeowner (not just seniors), which is broader than many neighboring states' age- or income-restricted programs, and is a standard piece of domicile evidence in a residency dispute.
Sales tax: State rate is 6.0%, with a statewide average combined rate (state plus local option sales tax) of about 6.94%.
Who This Move Applies To
Travel Nurses
In Indiana
Indiana applies its ordinary domicile and 183-day/permanent-residence tests to a travel nurse the same as anyone else: a nurse not domiciled in Indiana who keeps a permanent Indiana residence and is present more than 183 days becomes an Indiana resident on worldwide income for that year, plus the applicable county tax. The more frequent exposure runs the other way, where a nurse claims a Florida or Texas tax home while actually renting in Indiana for most of an assignment; Indiana taxes nonresident wages for days actually worked in the state regardless of the claimed tax home.
In Iowa
Iowa has no statutory carve-out for travel nurses distinct from its general domicile test; the federal tax-home question under IRS Publication 463 governs stipend treatment, and Iowa's domicile-continuity rule then applies independently. Iowa's major hospital systems in Des Moines, Cedar Rapids, and Iowa City draw a steady stream of travel nursing assignments, and this is also the specific fact pattern national travel-nurse forums warn about: nurses who claim a Florida or Texas tax home on paper while actually living in an Iowa rental apartment and rarely visiting the claimed home state have had their tax-home status disallowed, which exposes the tax-free stipends and typically requires filing an Iowa resident return alongside nonresident returns in every other state worked.
Professional Athletes
In Indiana
Indiana taxes nonresident professional athletes using the standard duty-day formula applied across nearly all income-tax states: total season compensation multiplied by the ratio of Indiana duty days (games, practices, and mandatory team functions in the state) to total duty days for the season. This applies to visiting NFL and NBA teams playing the Colts and Pacers in Indianapolis, and Indiana's flat, comparatively low rate means the dollar amount at stake per game is smaller than in higher-rate states, though the filing obligation is the same.
In Iowa
Iowa has no major professional sports franchise, though the University of Iowa and Iowa State athletic programs generate significant visiting-team and visiting-official travel, and touring concerts and events at Des Moines and Cedar Rapids venues bring nonresident performers into the state regularly. Iowa applies duty-day apportionment to nonresident athletes and entertainers earning income from Iowa events, consistent with how most income-tax states administer the jock tax.
Snowbirds, Long Visitors, and RVers
In Indiana
The Indiana snowbird risk runs through the same domicile-abandonment presumption that protects year-round Indiana residents: a retiree who keeps a permanent Indiana residence, continues to vote in Indiana, or keeps the homestead deduction active while wintering in Florida is presumed not to have abandoned Indiana domicile. Separately, spending more than 183 days in Indiana in a year while maintaining a permanent Indiana residence independently triggers Indiana residency regardless of domicile intent.
In Iowa
Because Iowa has no day-count statutory residency test, an Iowa snowbird who winters in Florida or Arizona does not face a bright-line day-count trigger the way a New York or Missouri resident with a similar arrangement would; the question is whether Iowa domicile has actually been abandoned and replaced, and Iowa's continuity rule means simply spending part of the year elsewhere does not by itself end Iowa residency. The Homestead Tax Credit is the practical tripwire: it requires the property be the claimant's primary residence, so a snowbird who spends the majority of the year in a warm-weather state should reassess whether continuing to claim it is still accurate.
Remote Workers
In Indiana
Indiana has no convenience-of-the-employer rule. A nonresident who works remotely from another state for an Indiana-based employer is generally not taxed by Indiana on those wages, since Indiana sources employee compensation to where the work is physically performed rather than to the employer's location.
In Iowa
Iowa has no convenience-of-the-employer rule, so a genuine Iowa resident working remotely for an out-of-state employer is taxed as an Iowa resident regardless of employer location, and a nonresident working remotely for an Iowa employer generally is not pulled into Iowa tax solely because the employer is headquartered there. The Quad Cities (Davenport/Bettendorf, Iowa and Rock Island/Moline, Illinois) and the Omaha-Council Bluffs metro both produce a meaningful population of cross-border remote and hybrid workers whose actual physical work location, not their employer's address, governs Iowa tax exposure.
Military
In Indiana
Indiana follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose domicile was Indiana before entering service remains an Indiana domiciliary regardless of duty station unless they affirmatively establish a new domicile, while a servicemember stationed in Indiana on orders, and a qualifying spouse, does not become an Indiana resident solely because of the posting; Indiana also allows a deduction for certain military retirement income.
In Iowa
Iowa follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Iowa remains an Iowa domiciliary and taxpayer regardless of duty station, and Iowa does not tax a nonresident servicemember's military pay solely because they are stationed in Iowa under orders. A nonmilitary spouse residing in Iowa solely due to military orders can elect the servicemember's state of legal residence under MSRRA for Iowa tax purposes.
Airline Crew
In Indiana
Federal law (49 U.S.C. §40116) limits states to taxing airline employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned, protecting flight crew based at Indianapolis International who are domiciled outside Indiana from full-income Indiana taxation based solely on their duty station.
In Iowa
Federal law (49 U.S.C. §40116) limits any state's ability to tax an air carrier employee's pay to the employee's state of residence and any state where more than 50% of pay is earned. Iowa's airports are not major airline crew bases, so this carve-out is less frequently in play for Iowa specifically, but it still protects any Iowa-domiciled crew member from having their full income pulled into a duty-station state's tax.
Tools for This Move
Indiana to Iowa FAQ
Does Indiana have a 183-day rule separate from domicile?+
Yes, and Indiana is explicit that the two are independent tests. Under IC 6-3-1-12 and 45 IAC 3.1-1-21, you're an Indiana resident if you're domiciled in Indiana, or separately, if you're not domiciled in Indiana but maintain a permanent Indiana residence and spend more than 183 days in the state during the year. Indiana's own guidance says the 183-day test is not itself a test for domicile, so you can fail one and still be caught by the other.
Does Iowa have a day-count rule like the 183-day tests other states use?+
No. Iowa relies entirely on domicile, not a day count. Once you're domiciled in Iowa, you stay an Iowa resident for tax purposes until you both intend to abandon Iowa domicile and actually relocate; simply spending months out of state doesn't end Iowa residency on its own, and there's no statutory day threshold that resets the clock.
If I move to Florida but keep voting absentee or in person in Indiana, does that hurt my case?+
Yes, directly. Indiana's domicile-abandonment rule under 45 IAC 3.1-1-22.5 presumes you haven't given up Indiana domicile if you keep a permanent Indiana residence and continue voting in Indiana, among other listed factors. Re-registering to vote in your new state, and actually voting there, is one of the more concrete steps that supports a genuine domicile change.
Is Iowa a flat tax state now?+
Yes. Iowa completed its transition to a flat 3.80% individual income tax rate starting with tax year 2025, replacing the old multi-bracket system. Income below $9,000 (single) or $13,500 (married filing jointly) owes no Iowa tax at all, and the exemption threshold is higher for filers 65 and older.
Will keeping the homestead deduction on my Indiana house hurt me if I claim I moved to Florida?+
Yes. Indiana law specifically directs the Department of Local Government Finance and county auditors to develop procedures to identify homestead deduction claimants whose actual principal residence is outside Indiana, so continuing to claim it while filing as a nonresident elsewhere is exactly the kind of contradiction those procedures are built to catch. If you've genuinely moved, notifying your county auditor to remove the deduction is one of the concrete steps supporting your new domicile.
Does Iowa still have an inheritance tax?+
No, Iowa fully repealed its inheritance tax as of January 1, 2025, the final step of a phase-out that had been reducing rates by 20 percentage points a year since 2021. Deaths occurring on or after that date owe no Iowa inheritance tax regardless of who inherits.
How does Indiana's county income tax work if I move counties or move out of state mid-year?+
On top of the flat 2.95% state rate, every Indiana county levies its own income tax, ranging roughly from 0.5% to over 3%, and your county rate generally depends on your county of residence. When you move into or out of Indiana mid-year, Form IT-40PNR handles both the state and county allocation for the split year, which makes Indiana's exit-year filing meaningfully more involved than a state with a single flat rate and no local layer.
I moved out of Iowa for a job but kept my Iowa house and driver's license just in case. Am I still an Iowa resident?+
Very likely yes. Iowa's domicile-continuity rule means your Iowa residency persists until you affirmatively abandon it, and keeping an Iowa driver's license and an available Iowa house are exactly the kind of evidence that shows you haven't actually abandoned Iowa domicile, regardless of how long you've been physically absent.
I live in Kentucky and work in Indiana. Do I owe Indiana income tax on my wages?+
No, not on wages. Indiana has reciprocity agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin, so a Kentucky resident's wages earned working in Indiana are taxed only by Kentucky, not Indiana, and Indiana withholding should not apply. Reciprocity covers wage income only; investment, rental, and business income from Indiana sources are still taxable by Indiana.
Does Iowa tax my retirement income?+
Not if you're 55 or older. Iowa fully exempts pensions, 401(k) and IRA distributions, and Social Security benefits for taxpayers 55 and up, a change that took effect for the 2023 tax year and makes Iowa notably more retirement-friendly than its flat income tax on wages might suggest.
Does Indiana tax my Social Security or pension after I retire?+
Social Security is fully exempt from both Indiana state and county tax. Pension, 401(k), and IRA distributions are taxed as ordinary income at the flat state rate plus your county's local rate, since Indiana doesn't offer the kind of broad age-based retirement income exclusion that Illinois or Michigan provide, aside from a modest deduction for certain military and railroad retirement income.
What form do I file if I only lived in Iowa part of the year?+
Part-year residents and nonresidents file Form IA 1040 along with Form IA 126, the Nonresident/Part-Year Resident Credit Schedule, which calculates what percentage of your income is Iowa-source and applies that ratio to your Iowa tax.
