Moving from Iowa to Louisiana: Residency, Taxes, and What to Prove

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.

In Louisiana

Louisiana's hospital systems in New Orleans and Baton Rouge draw significant travel-nurse staffing, and Louisiana taxes nonresident wages for work physically performed in the state regardless of the nurse's claimed tax home elsewhere, requiring a nonresident IT-540B on those wages. A nurse whose combined time in Louisiana across contracts exceeds six months while maintaining a place to stay risks the statutory-residency test pulling them into full resident status for the year.

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.

In Louisiana

The New Orleans Saints (NFL) and New Orleans Pelicans (NBA) are Louisiana's major professional franchises. Louisiana taxes nonresident athletes and entertainers on income allocated to duty days or performances in the state, the standard jock-tax structure, while Louisiana-domiciled players on those teams are taxed on their full salary as residents, subject to credits for tax paid to other states on road games.

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.

In Louisiana

Louisiana's statutory six-month-plus-abode test is the practical trap for long visitors: someone who splits time between a Louisiana camp or second home and another state can be pulled into full Louisiana residency simply by crossing 183 days while maintaining that Louisiana abode, regardless of where they consider themselves domiciled. Post-hurricane displacement (evacuation for Katrina, Ida, and similar storms) has also raised genuine questions about whether temporary out-of-state sheltering interrupts domicile; the general rule is that involuntary, temporary displacement does not by itself establish a new domicile or abandon the Louisiana one.

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.

In Louisiana

Louisiana has no convenience-of-the-employer rule; wages are sourced to where the work is physically performed. A Louisiana resident working remotely for an out-of-state employer owes Louisiana tax on that income as a resident, and someone who leaves Louisiana but still works occasional in-state days can owe nonresident tax on just those days.

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.

In Louisiana

Louisiana fully exempts military retirement pay from state income tax. Active-duty pay follows the servicemember's SCRA state of legal residence, and a nonresident military spouse in Louisiana solely due to the servicemember's orders can generally avoid Louisiana tax on their own income under the Military Spouses Residency Relief Act, provided they share the same non-Louisiana domicile as the servicemember.

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.

In Louisiana

Louisiana has no major airline hub or flight-crew domicile base comparable to Dallas-Fort Worth or Atlanta; Louis Armstrong New Orleans International is served by multiple carriers but is not a crew base of national significance, so the federal Mobile Workforce carve-out for air carrier employees has limited practical relevance for Louisiana residents specifically.
