Iowa 183-Day Rule Checker
Iowa has no bright-line day-count residency test. Here is what actually controls, and what a day count does and does not prove.
Iowa's actual test
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 controls instead
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.

This jurisdiction does not run a bright-line day-count residency test. Domicile, the place you treat as your true, fixed, permanent home, controls instead, regardless of how many days you spend here.

Iowa Day-Count FAQ
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.
Is Iowa an aggressive state for residency audits?+
No, Iowa 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. Iowa's domicile-continuity approach does mean the state can be persistent about treating someone as a resident until they've clearly abandoned Iowa ties, even without a day-count test to enforce.
How does Iowa treat travel nurses who claim a tax home somewhere else?+
Iowa has no separate statutory rule for travel nurses; the federal tax-home concept under IRS Publication 463 determines whether stipends stay tax-free, and Iowa's domicile-continuity test then applies just as it would to any other taxpayer. This is the exact pattern documented on national travel-nurse forums: a nurse who claims a Florida or Texas tax home while actually living in an Iowa rental most of the year and rarely visiting the claimed home state risks having that tax home disallowed, which would also mean filing an Iowa resident return.
