Moving from South Dakota to Tennessee: 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 Tennessee

Nashville, Memphis, and Knoxville's hospital systems are active travel-nursing markets, but since Tennessee has no income tax, a travel nurse working a Tennessee contract owes no Tennessee state tax on those wages regardless of tax-home status elsewhere; the nurse's tax exposure runs entirely through whatever state actually claims their tax home and any other income-tax states they work in during the year.

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 Tennessee

Tennessee is home to the Titans (NFL), Grizzlies (NBA), and Predators (NHL), and because the state has no individual income tax, it cannot and does not impose a jock tax on visiting players the way most other franchise states do; Tennessee-based players keep more of their income than a comparable player based in a state like California or New York, since neither their home-team income nor any Tennessee duty days are taxed at the state level (visiting players still may owe tax to their own home state and to other states with jock-tax regimes on away-game duty days, just not to Tennessee).

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 Tennessee

Tennessee is not a classic snowbird destination the way Florida or Arizona are, and because it has no income tax, long-term visitors face none of the statutory-residency day-count exposure that snowbirds worry about in states like New York, California, or Hawaii; a person splitting time between Tennessee and a high-tax state should instead focus their planning on that other state's day-count and domicile rules, since Tennessee itself creates no tax trigger.

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 Tennessee

A remote worker who relocates to Tennessee and works for an out-of-state employer owes no Tennessee tax on those wages, since there is nothing to tax; any exposure runs entirely through the employer's home state and whether that state applies a convenience-of-the-employer rule to the arrangement, which is the reason many remote workers specifically target no-income-tax states like Tennessee for the move.

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 Tennessee

Tennessee hosts significant military presence (Fort Campbell straddles the Tennessee/Kentucky line, Arnold Air Force Base, Millington Naval Support Activity), and follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act; since Tennessee has no income tax, SCRA and MSRRA questions here matter mainly for driver's license, vehicle registration, and voting purposes rather than tax liability.

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 Tennessee

Nashville International Airport is a growing Southwest Airlines base and a secondary hub for several carriers; federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence, which is moot for Tennessee-domiciled crew since Tennessee has no income tax to apply to any portion of their wages regardless of how flight time is distributed.
