Moving from Nevada to Idaho: Residency, Taxes, and What to Prove

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 Idaho

Boise's hospital systems and Idaho's rural-hospital travel contracts make the state a modest but real travel-nurse market. A nurse genuinely domiciled in Idaho who takes Idaho contracts is simply taxed as a resident. A nurse claiming an Idaho tax home while working elsewhere needs a real, regularly used, duplicated-expense Idaho residence; claiming Idaho as a federal away-from-home tax home while also trying to use the 445-day absence exception for Idaho state tax purposes is explicitly disqualifying under Idaho's own rule, so the two claims cannot be made consistently.

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 Idaho

Idaho has no major professional sports franchise in the four big US leagues, so jock-tax exposure runs almost entirely one direction: Idaho-domiciled or Idaho-resident athletes are taxed on income earned while playing in other states under those states' own apportionment rules, and nonresident athletes visiting Idaho for occasional events owe Idaho tax on Idaho-source duty days under the state's standard nonresident income sourcing.

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 Idaho

Idaho's 270-day statutory threshold is unusually generous compared to the 183-day standard most states use, but it comes paired with the strict any-part-of-a-day counting rule, so a snowbird or long-term visitor who owns or leases an Idaho home needs to track every day with any Idaho presence, not just overnight stays, against that 270-day ceiling. Idaho's own seasonal-worker example (a couple splitting time between an Alaska fishing operation and an Idaho off-season home) shows the state applies the ordinary domicile-or-270-day test to seasonal residents just as it would to anyone else, with no special seasonal carve-out.

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 Idaho

Idaho has no convenience-of-employer rule: a nonresident performing all work physically outside Idaho for an Idaho-based employer is not Idaho-taxed on those wages. Idaho, particularly the Boise metro area, has drawn a steady stream of remote workers relocating from higher-cost West Coast states since 2020; because Idaho and Washington are both community property states, a remote-working couple split between the two needs to account for the community-property income-sharing rule on their Idaho return, not just source-based sourcing.

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 Idaho

Idaho follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act, and Idaho's own guidance walks through the distinction between military home of record and state of legal residence/domicile: a service member stationed in Idaho under orders (for example, at Mountain Home Air Force Base) is taxed based on domicile, not the posting, active-duty military pay is not Idaho-taxed for nonresident service members, and a nonmilitary spouse can independently be a resident, part-year resident, or nonresident depending on their own domicile and MSRRA elections.

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.

In Idaho

Boise Airport is not a major airline crew base, so Idaho's most relevant federal transportation carve-out runs to interstate rail and motor carrier employees rather than airline crew specifically: Idaho's guidance confirms that employees of interstate rail or motor carriers with regularly assigned duties in more than one state are, under federal law, taxable only in their state of residence, with the Idaho-earned portion of a nonresident's income remaining Idaho-taxable.
