Moving from South Carolina to Nevada: Residency, Taxes, and What to Prove

In South Carolina

South Carolina's large hospital systems (MUSC in Charleston, Prisma Health, McLeod) make it a significant travel-nurse assignment market. Because South Carolina has no day-count residency trigger, a nurse working consecutive South Carolina contracts is not automatically pulled into residency the way they would be in a 183-day state; the exposure runs through South Carolina's domicile test instead, meaning a nurse who buys a home, registers to vote, or otherwise shows intent to make South Carolina permanent can become domiciled regardless of the nominal 'tax home' claimed elsewhere.

In Nevada

Nevada is a popular tax-home domicile choice for travel nurses precisely because Nevada itself never taxes the income, though every other state where the nurse takes an assignment still taxes the nonresident wages earned there. A Nevada tax home has to be a real, maintained residence the nurse actually returns to between contracts, not just a mailing address; without that, the IRS or another state can deny the tax-free stipend treatment and reclassify the housing allowance as wages.

In South Carolina

Charleston and Greenville host minor-league and college sports rather than a major-league franchise, so South Carolina's jock-tax exposure is almost entirely on the visiting-player side: nonresident athletes on teams playing in South Carolina owe apportioned South Carolina tax on the personal-service income allocated to South Carolina duty days, following the state's general rule taxing nonresidents on South Carolina-source personal service income.

In Nevada

Nevada is home to the Raiders, the Golden Knights, and the Aces. Nevada itself never taxes any athlete's income, but Nevada-domiciled athletes still owe nonresident jock tax in every state with an income tax where they play, based on duty-day apportionment. Nevada's appeal as a domicile is that it eliminates the home-state slice of that calculation entirely, unlike a high-tax home state that would otherwise tax 100% of income before credits.

In South Carolina

Because South Carolina runs no day-count test, a snowbird can spend an extended winter in South Carolina without becoming a resident, as long as they do not develop the intent to make South Carolina their permanent home; the Department's own guidance states a nonresident spending winter months in South Carolina does not automatically become a South Carolina resident. The risk flips for someone who buys a South Carolina home, joins clubs, opens local bank accounts, and gradually shifts their center of life there, as in Brown, where the taxpayer was found domiciled in South Carolina despite lacking a South Carolina driver's license or vehicle registration that year.

In Nevada

Las Vegas, Reno, and the Lake Tahoe area draw heavy seasonal traffic from California and other high-tax states. Because Nevada imposes no exit test of its own on people leaving, and no entry test creating Nevada tax liability, the entire audit risk in a snowbird's dual-home arrangement sits with the origin state's presumption rules (for example California's nine-month presumption), not with Nevada.

In South Carolina

South Carolina has no convenience-of-the-employer rule. A remote worker physically performing work from South Carolina owes South Carolina tax on that personal service income (since South Carolina taxes residents' personal service income regardless of source and nonresidents' South Carolina-source personal service income), and the credit for taxes paid to other states (Code § 12-6-3400) is the mechanism for avoiding double taxation if the employer's home state also asserts a claim.

In Nevada

There is no convenience-of-employer rule to worry about because Nevada has no income tax to apply one under. A remote worker who establishes genuine Nevada domicile owes $0 Nevada tax regardless of where their employer is headquartered, which is a major driver of remote-worker relocation to Nevada from California and other high-tax states.

In South Carolina

South Carolina follows the federal Servicemembers Civil Relief Act, the Military Spouses Residency Relief Act, and the Veterans Benefits and Transition Act: a servicemember does not lose or acquire South Carolina domicile solely by being present or absent under military orders, and a spouse may elect to use the servicemember's state of residence for tax purposes regardless of when the marriage occurred. Under S.C. Regulation 117-640.2, a servicemember who entered service while domiciled in South Carolina is presumed to remain a South Carolina resident for tax purposes unless they affirmatively establish a new domicile and abandon South Carolina, even if the new state (like Texas or Florida) has no income tax.

In Nevada

Nevada follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Because Nevada has no income tax, service members and spouses who elect Nevada domicile under MSRRA simply owe no state tax on military pay or spousal income. Nellis Air Force Base and Naval Air Station Fallon are both active hubs for service members establishing Nevada domicile for exactly this reason.

In South Carolina

Charlotte Douglas (just across the North Carolina line) and smaller in-state airports mean some airline crew live in South Carolina while based elsewhere. Federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence and, narrowly, a state where more than 50% of pay is earned; crew domiciled in South Carolina are taxed on personal service income under the state's standard resident rules.

In Nevada

Nevada hosts a crew base for Allegiant Air in Las Vegas. 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, but since Nevada itself never taxes income, Nevada-domiciled crew simply owe $0 Nevada tax and rely on the federal rule to limit exposure elsewhere.
