Moving from Guam to Alaska: Residency, Taxes, and What to Prove

In Guam

Guam is not a major travel-nurse assignment market compared to the 50 states, but Guam Memorial Hospital and private facilities do draw contract clinical staff; the underlying federal tax-home analysis is identical to any state, requiring genuine maintenance of and return to a Guam home between assignments to sustain a Guam tax-home claim.

In Alaska

Alaska is a genuine travel-nursing destination (Anchorage, Fairbanks, and rural hub hospitals pay premium rates for remote-area coverage), but since Alaska has no income tax, a travel nurse working an Alaska contract owes no Alaska state tax on those wages regardless of tax-home status elsewhere. The only residency question that matters here is whether a nurse who relocates to Alaska long-term wants to pursue PFD eligibility, which requires a full prior calendar year of residency and is generally not realistic for someone on a series of short travel contracts.

In Guam

No major U.S. professional sports franchise is based in Guam, so there is no home-team jock-tax apportionment regime specific to the territory. Visiting athletes or performers earning income from events physically held in Guam owe Guam-source tax on income attributable to that work under the mirrored federal withholding framework administered by DRT.

In Alaska

Alaska has no major professional sports franchises subject to jock-tax duty-day apportionment, and because the state has no income tax, it could not impose one on visiting athletes even if a franchise existed. This is a non-issue for Alaska.

In Guam

A mainland resident who buys a Guam property and spends significant time there while keeping a permanent mainland home risks failing the closer connection test even with a solid day count, unless family, banking, and business ties also shift to Guam. Publication 570's own example addresses a related pattern directly: someone with ties to both Guam and the CNMI must determine which is the actual tax home based on where their regular place of business is located, not simply where they own property.

In Alaska

Alaska's snowbird dynamic runs in reverse from Sun Belt states: Alaskans who winter in Arizona, Hawaii, or the Lower 48 to escape the cold risk crossing the 180-day cumulative absence threshold for PFD eligibility if that time away is not documented against an allowable absence category, since 'wanted warmer weather' is not itself one of the enumerated exceptions. A long-term visitor to Alaska who is not actually relocating does not become an Alaska resident by physical presence alone, since PFD eligibility requires the pre-January-1 affirmative-step evidence and a full qualifying calendar year of residency, not just time spent in the state.

In Guam

Guam has no convenience-of-the-employer rule of its own, but a mainland employer's own state convenience rule can still reach a Guam-based remote worker's wages if the employer continues to treat them as mainland-sourced. Guam's IRC section 931 exclusion for bona fide residents' Guam-source income is valuable, but only applies cleanly once the employer correctly treats the work as Guam-sourced and DRT-withheld rather than leaving it entangled with a mainland payroll system.

In Alaska

A remote worker who physically relocates to Alaska and works for an out-of-state employer owes no Alaska tax on those wages, since there is nothing to tax; the employer's home state may still apply its own convenience-of-employer rule to the arrangement, so the exposure runs entirely through the other state's rules, not Alaska's. Alaska residency itself, separate from the tax question, only matters here if the worker also wants PFD eligibility, which layers on the year-long residency and intent requirements above.

In Guam

Guam hosts significant U.S. military presence (Andersen Air Force Base and Naval Base Guam) and 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 due to Guam orders, and a civilian spouse can elect to keep the servicemember's tax residence. A servicemember who qualified as a bona fide Guam resident before deployment elsewhere does not lose that status due to absence under military orders, but being stationed on Guam under orders alone does not create bona fide residency.

In Alaska

Alaska hosts significant active-duty populations (JBER, Eielson AFB, Fort Wainwright), and follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember stationed in Alaska on orders does not become an Alaska domiciliary solely because of the posting. Separately, active duty military service is one of the PFD's specifically allowed absence categories, so an Alaska-resident servicemember posted outside the state on orders does not lose PFD eligibility for that absence, and a nonresident servicemember stationed in Alaska on orders generally cannot claim PFD residency based on the posting alone.

In Guam

Guam's A.B. Won Pat International Airport is a hub connection point for trans-Pacific carriers, and the federal carve-out at 49 U.S.C. section 40116, limiting 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 Guam the same way it applies to the 50 states. Crew who are bona fide Guam residents owe Guam tax on their wages under the mirrored federal framework rather than IRS tax on Guam-source pay.

In Alaska

Federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence, which is moot for Alaska-domiciled crew since Alaska has no income tax to apply to any portion of their wages regardless of where flight time is flown.
