Moving from Nebraska to Iowa: Residency, Taxes, and What to Prove
The top income tax rate drops from 4.55% in Nebraska to 3.80% (flat) in Iowa. Establishing Iowa residency correctly is what protects that benefit.
Residency Tests Side by Side
Nebraska'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 | Nebraska | Iowa |
|---|---|---|
| Statutory Residency Test | Nebraska's residency test is set directly by statute, Neb. Rev. Stat. §77-2714.01(7): a resident individual is one who is domiciled in Nebraska, or who is not domiciled in Nebraska but maintains a permanent place of abode in the state and spends in the aggregate more than six months (commonly applied as more than 183 days) of the taxable year in Nebraska. This gives Nebraska two independent paths into residency, domicile or the permanent-abode-plus-presence test, similar in structure to New York's and Missouri's statutory residency frameworks. | 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 | Nebraska applies the standard facts-and-circumstances domicile factors: permanent home location, driver's license and vehicle registration, voter registration, family and employment location, and financial ties. No published Nebraska regulation lists a closed set of weighted factors comparable to New York's; the Department of Revenue and courts apply the general common-law domicile test. | 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 | Nebraska's statute does not define whether a partial day counts toward the more-than-six-months threshold for non-domiciliaries maintaining a permanent Nebraska abode. No published Department of Revenue guidance sets a bright-line any-part-of-a-day standard comparable to New York's or California's, so this is treated as a facts-and-circumstances presence question rather than a strict per-day trigger. | 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. |

Leaving Nebraska
Nebraska is not among the aggressive exit-audit states most frequently named on r/tax and by practitioners, a list dominated by New York, California, New Jersey, Connecticut, Maryland, and Minnesota. The state's real residency friction is more likely to arise from its own statutory permanent-abode-plus-183-day test: a taxpayer who claims to have left Nebraska but keeps a Nebraska home available and returns often enough to cross six months of aggregate presence becomes a Nebraska statutory resident regardless of where they consider their true domicile to be. Omaha's proximity to Council Bluffs, Iowa, across the Missouri River also creates a smaller-scale version of the metro-straddling residency issue seen in Kansas City and St. Louis.
Trailing Income
Nebraska continues to tax Nebraska-source income earned by a nonresident after departure: wages for work physically performed in Nebraska, Nebraska-based business income, and gain on Nebraska real property. Nebraska has no published convenience-of-the-employer rule, so a former Nebraska resident working remotely for a Nebraska employer after relocating is generally not taxed by Nebraska on those wages solely because the employer is Nebraska-based.
Part-Year Filing
Part-year residents and nonresidents file Nebraska Form 1040N together with the Nebraska Schedule III, Computation of Nebraska Tax for Nonresidents and Partial-Year Residents, which allocates Nebraska-source income and applies the appropriate ratio to compute Nebraska tax due.
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
Vehicle Registration Deadline
30 days
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
Nebraska Top Rate
4.55%
Iowa Top Rate
3.80% (flat)
Moving from Nebraska to Iowa drops the top marginal income tax rate from about 4.55% to about 3.8%, a reduction of roughly 0.75 percentage points.
Withholding Reciprocity
Nebraska 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
Nebraska and Iowa both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Nebraska
Capital gains: Nebraska has no separate capital gains rate; gains flow through federal adjusted gross income into Nebraska taxable income and are taxed at the same graduated rates as ordinary income, aside from a narrow special election available to certain shareholders on the sale of stock in a Nebraska corporation held long-term.
Estate or inheritance tax: Nebraska is one of the few remaining states with an inheritance tax, administered at the county level rather than the state level. Rates and exemptions vary by the heir's relationship to the decedent: close relatives (spouses are fully exempt; children and other close family get a higher exemption and lower rate) pay less than distant relatives or unrelated heirs. LB 310 (2022) and later legislation raised exemptions and lowered rates in stages through 2025, softening what had been one of the more burdensome inheritance tax regimes in the country. Nebraska has no separate state-level estate tax.
Property tax: Effective property tax rate on owner-occupied housing runs about 1.44%, among the higher rates in the region and a persistent point of political pressure in the state. Nebraska's homestead exemption program reduces taxable value for qualifying elderly, disabled, and disabled veteran homeowners, subject to income caps that are adjusted annually.
Sales tax: State rate is 5.5%, with a statewide average combined rate (state plus local) of about 6.98%.
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 Nebraska
Nebraska has no statutory carve-out for travel nurses distinct from its general residency test; the federal tax-home question under IRS Publication 463 governs stipend treatment, and Nebraska's statutory permanent-abode-plus-183-day test then applies independently. Omaha's large hospital systems (Nebraska Medicine, CHI Health) draw a steady stream of travel nursing assignments, and a nurse who claims an out-of-state tax home while actually maintaining a Nebraska residence and spending more than six months in the state during the year risks Nebraska statutory residency regardless of the federal stipend question.
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 Nebraska
Nebraska has no major professional sports franchise, though the University of Nebraska's athletic programs generate significant visiting-team and visiting-official travel. Nebraska applies duty-day apportionment to nonresident athletes and entertainers who earn income from events held in the state, consistent with how most income-tax states administer the jock tax for touring and visiting performers.
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 Nebraska
A Nebraska snowbird who is Nebraska-domiciled and winters in Arizona or Florida remains a Nebraska domiciliary unless they take affirmative steps to change domicile; simply spending part of the year away does not by itself end Nebraska residency. A non-domiciled owner of a Nebraska vacation or second home faces the statutory test directly: maintaining a permanent Nebraska abode and spending more than six months (roughly 183 days) in the state during the year makes them a Nebraska statutory resident regardless of where they consider their true domicile.
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 Nebraska
Nebraska has no convenience-of-the-employer rule, so a genuine Nebraska resident working remotely for an out-of-state employer is taxed as a Nebraska resident regardless of employer location, and a nonresident working remotely for a Nebraska employer generally is not pulled into Nebraska tax solely because the employer is headquartered there. Omaha's status as a regional corporate hub (Berkshire Hathaway, Union Pacific, several major insurers) means a meaningful population of remote and hybrid workers whose employer is Nebraska-based but who live in Iowa or elsewhere; Nebraska's statutory abode-plus-presence test, not the employer's location, governs whether they owe Nebraska tax.
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 Nebraska
Nebraska follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Nebraska remains a Nebraska domiciliary and taxpayer regardless of duty station, and Nebraska does not tax a nonresident servicemember's military pay solely because they are stationed in Nebraska under orders. Offutt Air Force Base near Omaha is the state's major installation, and a nonmilitary spouse residing in Nebraska solely due to military orders can elect the servicemember's state of legal residence under MSRRA.
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 Nebraska
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. Eppley Airfield in Omaha is not a major airline crew base, so this carve-out is less frequently in play for Nebraska specifically, but it still protects any Nebraska-domiciled crew member from having their full income pulled into a duty-station state's tax.
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
Nebraska to Iowa FAQ
Does Nebraska use a 183-day rule?+
Effectively yes, but only for people who aren't Nebraska-domiciled. Nebraska statute treats you as a resident if you're domiciled in Nebraska, full stop, or if you're not domiciled in Nebraska but maintain a permanent Nebraska home and spend more than six months (in practice, more than 183 days) in the state during the year. If you're Nebraska-domiciled, the day count doesn't save you; you need to actually change your domicile.
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.
I moved out of Nebraska but still own the house and visit often. Am I still a resident?+
It depends which side of the domicile line you're on. If you're still Nebraska-domiciled, occasional visits don't change anything, you're still a resident regardless of day count. If you've genuinely changed your domicile elsewhere but kept the Nebraska house available and usable, you become a Nebraska statutory resident anyway if your total days in Nebraska for the year exceed roughly 183, so frequent return visits to a retained property are exactly what trips this test.
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.
Does Nebraska tax Social Security benefits?+
No, Nebraska fully exempts Social Security benefits from state income tax as of tax year 2024, following a multi-year phase-in of the exclusion.
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.
What form do I file if I only lived in Nebraska part of the year?+
Part-year residents and nonresidents file Nebraska Form 1040N along with Nebraska Schedule III, which allocates Nebraska-source income and computes the appropriate ratio to apply to your Nebraska tax.
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.
Does Nebraska really still have an inheritance tax?+
Yes, Nebraska is one of the few remaining states with an inheritance tax, and it's collected at the county level rather than by the state. Rates and exemptions depend on how closely related the heir is to the decedent, spouses are exempt and close family gets a lower rate and higher exemption than distant relatives or unrelated heirs. Legislation in 2022 and after (LB 310 and subsequent bills) raised exemptions and cut rates in stages through 2025, making it meaningfully less burdensome than it used to be, but it hasn't been repealed.
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.
Is Nebraska an aggressive state for residency audits?+
No, Nebraska is not on the short list of states practitioners and taxpayer forums consistently flag as aggressive, a list dominated by New York, California, New Jersey, Connecticut, Maryland, and Minnesota. That said, Nebraska's statutory permanent-abode-plus-183-day test is a real, objective trigger for anyone who keeps a Nebraska home after claiming to have moved.
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.
