Moving from Montana to U.S. Virgin Islands: Residency, Taxes, and What to Prove

In Montana

Billings, Missoula, and Montana's regional hospital systems generate real but modest travel-nurse demand given the state's population. A nurse genuinely domiciled in Montana who takes Montana contracts is taxed as an ordinary resident. A nurse claiming a Montana tax home while working elsewhere needs a real, regularly used, duplicated-expense Montana residence, since Montana's facts-and-circumstances domicile standard applies the same evidentiary weight to a claimed tax home as it does to any other domicile dispute.

In U.S. Virgin Islands

The USVI is not a major travel-nurse assignment hub, but the federal tax-home analysis applies identically: a nurse claiming a USVI tax home for stipend purposes must genuinely maintain and return to a USVI home between mainland assignments, not simply hold a mailing address there, or risk having both the stipend tax-home claim and any bona fide residency position challenged together.

In Montana

Montana has no major professional franchise in the four big US leagues, so jock-tax exposure runs primarily one direction: Montana-domiciled athletes playing professionally elsewhere are taxed by those other states under their own apportionment rules, while nonresident athletes competing in occasional Montana events (college sports revenue aside) owe Montana tax on Montana-source income under standard nonresident sourcing.

In U.S. Virgin Islands

No major U.S. professional sports franchise is based in the USVI, so there is no home-team jock-tax apportionment regime. Visiting athletes competing in USVI-based events or exhibitions owe USVI-source tax on income attributable to duty days physically worked in the territory under the mirrored federal withholding framework administered by BIR.

In Montana

Because Montana's permanent-place-of-abode test has no codified day-count threshold, a long-term visitor or second-home owner in a resort area like Whitefish, Big Sky, or the Flathead Valley cannot rely on staying under a specific number of days the way they could in a state with a 183-day rule; the Department instead weighs the full facts and circumstances of how the home is used and how much time is actually spent there. Montana's own domiciliaries who winter in Arizona or elsewhere remain presumed Montana residents under the 'residence cannot be lost until another is gained' rule unless they affirmatively establish a new domicile.

In U.S. Virgin Islands

A mainland resident who buys a USVI vacation property and spends significant time there while keeping a permanent mainland home is the classic closer-connection failure pattern; Vento illustrates exactly this dynamic, where family members with the same island property and similar day counts reached different residency outcomes because their individual ties to the mainland differed. Simply hitting a day-count threshold is not enough if family, banking, and business remain mainland-centered.

In Montana

Montana has no convenience-of-employer rule: a nonresident performing all work physically outside Montana for a Montana-based employer is not Montana-taxed on those wages. Montana, particularly Bozeman, Missoula, and the Flathead Valley around Whitefish and Kalispell, has drawn a wave of remote workers relocating from higher-cost states since 2020, and the lack of a sales tax is a frequently cited draw alongside the income tax simplification.

In U.S. Virgin Islands

The USVI has no convenience-of-the-employer rule of its own, but a mainland employer's own state convenience rule can still reach a USVI-based remote worker's wages if the employer continues to treat them as sourced to the mainland office. This is a real friction point because most mainland payroll systems are not set up to withhold for BIR, and getting an employer to correctly register and withhold for the USVI is often the first practical obstacle for a new remote-worker resident.

In Montana

Montana follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A service member stationed in Montana under orders (Malmstrom Air Force Base near Great Falls is the state's major installation) does not become Montana-domiciled from the posting alone. Montana's 2024 tax simplification added a subtraction for certain resident working military retirees and military survivor-benefit recipients, on top of the general federal SCRA/MSRRA protections.

In U.S. Virgin Islands

The USVI follows the federal Servicemembers Civil Relief Act (SCRA) and Military Spouses Residency Relief Act (MSRRA): a servicemember's home-of-record does not change solely because of orders stationing them in the USVI, and a civilian spouse can elect to keep the servicemember's tax residence when relocating under military orders. A servicemember who qualified as a bona fide USVI resident in an earlier year does not lose that status due to an absence in compliance with military orders, but merely being stationed there under orders does not itself create bona fide residency.

In Montana

Montana's airports (Bozeman Yellowstone International being the busiest) are not major airline crew bases, so the more relevant federal carve-out for Montana residents working in transportation is the interstate rail and motor carrier employee rule: federal law limits taxation of such employees with regularly assigned duties in more than one state to their state of residence.

In U.S. Virgin Islands

The federal carve-out at 49 U.S.C. section 40116, which limits taxation of air carrier employees to their state or territory of residence and, in limited cases, a jurisdiction where they earn more than half their pay, applies to the USVI the same way it applies to the 50 states. Crew who are bona fide USVI residents owe USVI tax on their wages under the mirrored federal framework rather than IRS tax on USVI-source pay.
