Moving from South Dakota to Arkansas: Residency, Taxes, and What to Prove

In South Dakota

South Dakota is a genuine, common tax-home domicile choice for travel nurses because it imposes no income tax and its driver's license rule (one overnight stay plus a mailing address) is achievable even for someone who is only in the state briefly between assignments. As with any tax-home claim, the IRS still requires the nurse to actually maintain and periodically return to a real home base, not just a mailing address, or the tax-free housing stipend can be reclassified as taxable wages; a South Dakota mail-forwarding address with no genuine pattern of returning to the state is a weaker tax-home claim than one paired with real, if infrequent, physical presence.

In Arkansas

Northwest Arkansas's hospital growth and rural facilities statewide create real travel-nurse demand. Arkansas taxes nonresident wages for work physically performed in the state regardless of the nurse's claimed tax home, requiring a nonresident AR1000NR on that income, and because any one prong of Arkansas's three-pronged test is enough to establish residency, a nurse who maintains lodging in Arkansas and crosses 183 days there across contracts risks being pulled into full resident status rather than nonresident treatment.

In South Dakota

South Dakota has no major professional sports franchise. South Dakota itself never taxes any athlete's income regardless of domicile, but a South Dakota-domiciled athlete still owes nonresident jock tax in every state with an income tax where they play, based on duty-day apportionment; South Dakota's appeal as a domicile is that it eliminates the home-state slice of that calculation entirely.

In Arkansas

Arkansas has no major professional sports franchise (the Razorbacks are a college program, not a professional team), so it is not a significant duty-day jurisdiction for the traditional pro-athlete jock tax the way Texas, Oklahoma, or Louisiana are with their franchises. College athlete NIL income sourced to Arkansas is a newer area where formal state guidance is still developing.

In South Dakota

South Dakota is less commonly the destination for classic snowbird arrangements (that role is dominated by Florida, Arizona, and Texas) and more commonly the domicile-of-record for people who are mobile year-round, especially full-time RVers who don't have a fixed second home anywhere. Because South Dakota imposes no exit test of its own on people leaving and no entry test creating South Dakota tax liability, the entire audit risk in a South Dakota domicile arrangement sits with whatever state the person actually spends significant time in, most often assessed under that state's own statutory residency or day-count rules.

In Arkansas

Arkansas's three-pronged test is the sharpest trap for long visitors of the states in this comparison set, because satisfying any single prong establishes residency rather than requiring both an abode and a day count together. A part-year visitor who keeps a place to stay in Arkansas and spends more than six months there in a given year can be treated as a resident even without ever intending Arkansas as a permanent domicile.

In South Dakota

There is no convenience-of-the-employer rule to worry about because South Dakota has no income tax to apply one under. A remote worker who establishes genuine South Dakota domicile, meaning an actual driver's license, mailing address, and a credible pattern of connection to the state, owes $0 South Dakota tax regardless of where their employer is headquartered, which has made South Dakota a popular domicile choice for remote workers leaving California, New York, and other high-tax states, alongside Texas and Florida.

In Arkansas

Arkansas has no convenience-of-the-employer rule; wages are sourced to where work is physically performed. A remote worker living in Arkansas and working for an out-of-state employer owes Arkansas tax on that income as a resident, while someone who moves away but still occasionally performs work from Arkansas can owe nonresident tax on just those days.

In South Dakota

South Dakota follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Because South Dakota has no income tax, service members and spouses who elect South Dakota domicile under MSRRA simply owe no state tax on military pay or spousal income. Ellsworth Air Force Base near Rapid City is the state's major installation and a common source of South Dakota domicile elections among service members and their spouses.

In Arkansas

Arkansas 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 present in Arkansas solely due to military orders can generally avoid Arkansas tax on their own wages under the Military Spouses Residency Relief Act if they share the servicemember's non-Arkansas domicile.

In South Dakota

Federal law (49 U.S.C. §40116) limits taxation of air carrier employees to their state of residence and any state where they earn more than 50% of pay. South Dakota is not a major airline crew base, but since South Dakota itself never taxes income, South Dakota-domiciled crew simply owe $0 South Dakota tax and rely on the federal rule to limit exposure to whichever state actually taxes them.

In Arkansas

Arkansas has no major airline hub or flight-crew domicile base; Northwest Arkansas National Airport has grown alongside the Walmart, Tyson, and J.B. Hunt corporate presence in the region, but it functions as a corporate and leisure airport, not a crew base, so the federal Mobile Workforce carve-out for air carrier employees has limited practical relevance for Arkansas residents.
