Moving from American Samoa to Utah: Residency, Taxes, and What to Prove
The top income tax rate drops from Secondary sources cite individual rates ranging from roughly 4% to 15%; the American Samoa Government Tax Office administers the schedule directly and does not publish an English-language bracket table online, so a filer should confirm the current-year schedule directly with the Tax Office in American Samoa to 4.45% in Utah. Establishing Utah residency correctly is what protects that benefit.
Residency Tests Side by Side
American Samoa and Utah both use a 183-day statutory residency threshold, so the day-count mechanics will feel familiar even though the underlying facts and enforcement differ.
| Factor | American Samoa | Utah |
|---|---|---|
| Statutory Residency Test | American Samoa uses the same federal IRC section 937 bona fide residency test that applies to all five territories: the presence test, the tax home test, and the closer connection test, all of which must be met for the same tax year. This federal test determines whether someone's American Samoa-source income is exempt from U.S. tax; American Samoa's own independent tax code separately determines what is owed to the territory itself. | Utah Code §59-10-103(1)(q) and Rule R865-9I-2 define a resident individual as either someone domiciled in Utah for any part of the tax year, or someone not domiciled in Utah who maintains a permanent place of abode in Utah and spends, in the aggregate, 183 or more days of the taxable year in the state. |
| Domicile Test | Closer connection functions as the domicile test, weighing permanent home, family, personal belongings, social/cultural/religious affiliations (which in American Samoa often includes matai title and extended-family/aiga ties), banking, business activity, and the jurisdiction of a driver's license and voter registration, against the total of U.S. and foreign-country contacts under Treasury Regulation 1.937-1(c). | Utah's domicile statute, §59-10-136, is unusual among states: it lists automatic domicile triggers before reaching the general facts-and-circumstances test. An individual is considered domiciled in Utah if a dependent claimed on their federal return is enrolled in Utah public school, if the individual or spouse is a Utah resident student enrolled in a Utah higher-education institution, or if the individual or spouse votes in a Utah election in that tax year without having registered to vote in another state. Only if none of those triggers apply does the statute fall back to the general rule: a permanent home in Utah the person intends to return to, combined with voluntarily fixing habitation here for other than a special or temporary purpose, evaluated under a 'preponderance of the evidence' standard across a long list of factors including driver's license, the primary-residence property tax exemption, spouse or dependent presence, vehicle registration state, church or club membership, and mailing address on record. |
| Day Count Threshold | 183 days | 183 days |
| Any Part of a Day Rule | Any part of a day physically present in American Samoa counts as a full presence day, and a day spent in both American Samoa and the mainland U.S. counts toward American Samoa. Publication 570 includes an American Samoa-specific example involving a fishing-vessel worker: days spent on a vessel predominantly used in local and international waters do not count as a tax home outside the territory, a rule of particular relevance to American Samoa's tuna-fleet economy. | Utah's current administrative rule (R865-9I-2, implementing §59-10-136) defines a countable day as one on which the individual spends more time in Utah than in any other single state, a majority-of-day standard rather than the any-part-of-a-day rule used in states like New York. This is a change from the Tax Commission's own 1997 advisory opinion (97-016), which stated under the prior statute that 'a fraction of a calendar day shall be counted as a whole day'; the current rule text supersedes that older, stricter reading. |
| Presumptions | None published | None published beyond the domicile triggers described above; Utah does not publish a separate day-count presumption analogous to California's nine-month or New Mexico's 185-day rule. |
| Safe Harbors | 183-day presence test; 549-day / 3-year test; 90-day U.S. cap; Low U.S.-earned-income test; No significant U.S. connection | None published |
Leaving American Samoa
No widely published American Samoa-specific bona fide residency court case surfaced in research. Exit exposure runs through the same federal IRC section 937 framework used across the territories, but American Samoa's independent tax system and its status as one of the smaller, less economically active territories mean it has not attracted the concentrated IRS compliance-campaign attention that Puerto Rico's Act 60 program has.
Trailing Income
Bona fide residents of American Samoa may not exclude gain from the disposition of certain U.S.-connected property (stock in a U.S. corporation, U.S. real estate, and similar assets) held in the 10 years before becoming a bona fide resident; that gain remains U.S.-source and subject to U.S. tax under the special rules in Publication 570. This 10-year lookback applies the same way to Puerto Rico. For the mirror-code territories (CNMI, Guam, and the USVI), Publication 570 frames the same 10-year-lookback property differently: that gain simply will not qualify for the local tax-reduction or rebate mechanisms those territories otherwise offer bona fide residents on territory-source income.
Part-Year Filing
Form 390 is American Samoa's individual tax return. A bona fide resident generally files an American Samoa return reporting gross income from worldwide sources and files a U.S. return only if required, excluding American Samoa-source income using Form 4563 attached to Form 1040 or 1040-SR. A U.S. citizen who was a bona fide American Samoa resident for at least two years before the move can qualify as a bona fide resident for the part of the tax year before the move, under the same year-of-move framework Publication 570 applies across the territories.
Enforcement Methods
Common Exit Mistakes
Establishing Utah Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a Utah driver's license | Driver License Division (DLD), Utah Department of Public Safety | within 60 days of establishing residency |
| Title and register vehicles in Utah | Utah DMV, Utah State Tax Commission | within 60 days of establishing residency |
| Register to vote | Utah Lieutenant Governor's Office / county clerk | 11 days before an election for online or mail registration; same-day registration is available in person at an early voting location or vote center through Election Day |
Declaration of Domicile
Utah has no formal declaration-of-domicile filing comparable to Florida's. Because §59-10-136 treats specific acts (enrolling a dependent in Utah public school, voting in Utah without registering elsewhere, claiming resident-student status) as automatic domicile triggers, the fastest documented path to Utah domicile is often simply registering to vote here and not being registered anywhere else, combined with the general permanent-home-and-intent factors.
Homestead
Utah's homestead exemption under Utah Code §78B-5-503 automatically protects up to $42,000 of equity in a primary personal residence from most judgment creditors (versus $5,000 for property that is not the primary residence), without any filing requirement. This is a creditor-protection statute, not the same thing as the separate 45% primary-residence property tax exemption; together they mean Utah cross-checks 'primary residence' status through both the tax assessor's exemption records and, in a dispute, the homestead-exemption claim itself.
Voter Registration
Online or mail registration must be received by the county clerk 11 days before an election; Utah also allows same-day registration in person at an early voting location or vote center, including on Election Day. https://vote.utah.gov
Vehicle Registration Deadline
60 days
New Resident Tax Traps
Utah taxes a new resident's income from the date Utah domicile begins, which, per §59-10-136, can be triggered automatically and immediately by enrolling a child in a Utah public school or by voting in a Utah election in that same tax year, even before the person has moved most of their belongings or spent significant time in the state.
What Changes on Tax
American Samoa Top Rate
Secondary sources cite individual rates ranging from roughly 4% to 15%; the American Samoa Government Tax Office administers the schedule directly and does not publish an English-language bracket table online, so a filer should confirm the current-year schedule directly with the Tax Office
Utah Top Rate
4.45%
Moving from American Samoa to Utah drops the top marginal income tax rate from about 15% to about 4.45%, a reduction of roughly 10.55 percentage points.
Withholding Reciprocity
American Samoa and Utah do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
American Samoa and Utah both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
American Samoa
Capital gains: American Samoa taxes capital gains under its own code, modeled on but not identical to the federal framework; no separate 0%-style preferential regime comparable to Puerto Rico's Act 60 has surfaced in research, and bona fide residents should confirm current treatment directly with the ASG Tax Office.
Estate or inheritance tax: No separate American Samoa territorial estate or inheritance tax was identified in research; because most land is communally held rather than individually owned and cannot pass through ordinary inheritance to non-Samoans, estate planning in American Samoa is governed as much by customary land law (matai/family succession) as by tax law.
Property tax: Effective property tax rates are described by secondary sources as very low, well under 1% of property value annually, but the more important fact for most people is that over 90% of American Samoa's land is communal land held by extended families under the matai (chief) system and generally cannot be purchased outright by non-natives, so 'property tax' is a minor issue for most newcomers compared to the land-access question itself.
Sales tax: American Samoa has no general state-level sales tax comparable to a mainland state; secondary sources describe local excise-style and business taxes rather than a broad retail sales tax, and current details should be confirmed with the ASG Tax Office.
Utah
Capital gains: Taxed as ordinary income at the flat rate with no separate capital gains rate or general exclusion. Utah offers targeted, narrow credits elsewhere in the code (for example, an angel investor tax credit), but there is no broad long-term capital gains subtraction comparable to Arizona's or Colorado's.
Estate or inheritance tax: None. Utah has no estate tax and no inheritance tax.
Property tax: Effective rate is roughly 0.48% of value, among the lower rates nationally. Utah's primary-residence exemption reduces the taxable value of an owner-occupied home by 45%, so property tax is assessed on only 55% of fair market value; it applies automatically to a household's primary residence but not to second homes.
Sales tax: 6.10% state rate, with an average combined state-and-local rate of about 7.19% once city and county add-ons are included.
Who This Move Applies To
Travel Nurses
In American Samoa
American Samoa has essentially no travel-nurse assignment market comparable to the 50 states or even Guam; the territory's single hospital system (LBJ Tropical Medical Center) is not a typical travel-nursing agency placement, so this persona is largely not applicable here. The underlying federal tax-home principles would apply identically if it ever were.
In Utah
Salt Lake City and the Wasatch Front hospital systems (Intermountain Health, University of Utah Health) make Utah an active travel-nurse market. A nurse who is genuinely Utah-domiciled and takes Utah contracts is taxed as an ordinary resident. A nurse claiming a Utah tax home while working assignments elsewhere needs a real, regularly used, duplicated-expense Utah residence; Utah's own domicile factor list (driver's license, voter registration, mailing address) is the same list an IRS or state auditor would use to test whether a claimed tax home is genuine.
Professional Athletes
In American Samoa
No major U.S. professional sports franchise is based in American Samoa, and there is no jock-tax apportionment regime. American Samoa is, however, well known as an outsized per-capita source of NFL and college football talent; players who grew up there and later earn NFL income are taxed on that income under the ordinary duty-day rules of whatever states and teams they play for, not under any American Samoa-specific regime.
In Utah
The Utah Jazz (NBA) and Real Salt Lake (MLS) are Utah's major professional franchises, and nonresident athletes on visiting teams owe Utah tax on Utah duty days under standard apportionment against total season duty days. Utah's flat 4.45% rate keeps the jock-tax burden comparatively modest next to graduated-rate states.
Snowbirds, Long Visitors, and RVers
In American Samoa
Long-term visitors face the same closer-connection analysis as anywhere else, complicated by the land-tenure system: without the ability to buy communal land outright, a snowbird-style arrangement in American Samoa typically means a long-term lease rather than home ownership, which changes the kind of documentary evidence (lease agreements, utility bills in the resident's name) that would need to substitute for a deed or homestead filing in a residency dispute.
In Utah
Utah's Park City and Deer Valley resort corridor draws the same kind of second-home buyer as Colorado's mountain towns. Because the statutory 183-day test only applies to someone who is not domiciled in Utah but maintains a permanent place of abode here, an out-of-state owner of a Park City ski home needs to track aggregate Utah days against 183 using the state's majority-of-day counting rule; a day only counts as a Utah day if more time was spent in Utah than in any other single state that day, which is more forgiving than states using an any-part-of-a-day standard.
Remote Workers
In American Samoa
American Samoa has no convenience-of-the-employer rule, and because it runs a separate tax code rather than a mirror code, a mainland employer's payroll system is even less likely to be set up to handle American Samoa withholding correctly than for Guam or the USVI. A remote worker relocating to American Samoa should expect to actively manage employer withholding and filing status rather than assume standard mainland payroll processes will translate correctly.
In Utah
Utah has no convenience-of-employer rule: a nonresident performing all work physically outside Utah for a Utah-based employer is not Utah-taxed on those wages. Utah has been a significant landing spot for remote tech workers (the Silicon Slopes corridor between Salt Lake City and Provo) relocating from California and elsewhere; because domicile can be triggered automatically by voting or school enrollment under §59-10-136, remote workers who move mid-year should be deliberate about the order in which they register to vote and enroll children in school relative to their old state.
Military
In American Samoa
American Samoa follows the federal Servicemembers Civil Relief Act (SCRA) and Military Spouses Residency Relief Act (MSRRA), and Publication 570 specifically addresses active-duty members whose state of legal residence is American Samoa: their military pay is American Samoa-source income and follows the U.S. Government employee wage rules described above regardless of duty station, meaning it is taxable on the U.S. return even though they are American Samoa residents.
In Utah
Utah follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Hill Air Force Base, north of Salt Lake City, is a major installation; a service member stationed in Utah under orders does not become Utah-domiciled from the posting alone, and Utah offers a full exemption for active-duty military pay along with credits addressing military retirement income.
Airline Crew
In American Samoa
Pago Pago International Airport has limited scheduled service compared to Guam or the mainland, and American Samoa is not a significant airline crew base; the federal carve-out at 49 U.S.C. section 40116 for air carrier employees would apply the same way it does elsewhere if it became relevant, but this is a marginal persona for American Samoa specifically.
In Utah
Salt Lake City International Airport (SLC) is a major hub for Delta Air Lines and the primary base for regional carrier SkyWest Airlines, giving Utah a substantial resident airline crew population. Federal law (49 U.S.C. §40116) limits state taxation of air carrier employees to their state of residence and any state where they earn more than 50% of their pay.
Tools for This Move
American Samoa to Utah FAQ
Is American Samoa's tax system the same as Guam's or the US Virgin Islands'?+
No. Guam, the USVI, and the CNMI use a 'mirror code' that applies the U.S. Internal Revenue Code word for word with the territory's name substituted in. American Samoa has its own separate and independent tax system: A.S.C.A. section 11.0403 incorporates much of the Internal Revenue Code by reference, so the law is modeled on federal law, but rates and specific rules are set independently by the American Samoa Government, not automatically updated when Congress changes the federal code.
Does Utah use the 183-day rule?+
Yes, but only as a backstop to domicile. If you're not domiciled in Utah, you still become a statutory resident if you keep a permanent place of abode in Utah and spend 183 or more days here in the aggregate during the year. Utah counts a day toward that total only if you spent more time in Utah that day than in any other single state, a more forgiving standard than states that count any part of a day.
Can I buy a house in American Samoa the way I would in any other U.S. territory?+
Generally, no. Over 90% of American Samoa's land is communally owned by extended families under the matai (chief) system, and non-natives cannot acquire that land outright; transferring communal land to individual ownership requires Land Commission recommendation and Governor approval, or 30 years of adverse possession. Most non-native residents live under a long-term lease rather than owning a home, which changes what proof-of-residence documentation looks like compared to anywhere else in this guide.
If I enroll my kid in a Utah public school, does that make me a Utah resident for tax purposes?+
It can, automatically. Utah Code §59-10-136 treats a dependent's enrollment in Utah public kindergarten, elementary, or secondary school as an automatic domicile trigger for the parent claiming that dependent, independent of the general intent-based domicile test, unless a specific noncustodial-parent exception applies.
Do I pay U.S. federal income tax on income I earn in American Samoa?+
If you're a bona fide American Samoa resident under the federal presence, tax home, and closer connection tests, your American Samoa-source income is generally exempt from U.S. federal tax. You do need to report worldwide income on your American Samoa return, and if you have non-American Samoa-source income above the filing threshold, you'll still need to file a U.S. return excluding the American Samoa income using Form 4563.
Can voting in Utah make me a Utah tax resident even if I haven't moved everything yet?+
Yes. If you or your spouse vote in a Utah election in a given tax year and have not registered to vote in another state, that alone establishes Utah domicile under §59-10-136(1)(a)(iii), regardless of how much of the year you actually spent in Utah.
I work for the U.S. Government in American Samoa. Is my pay exempt like other residents' income?+
No, and this is a common and costly misunderstanding. Publication 570 specifically requires that wages and cost-of-living allowances paid by the U.S. Government for services performed in American Samoa be included in gross income on both your U.S. and American Samoa income tax returns, regardless of whether you are a bona fide American Samoa resident. A foreign tax credit is available for the American Samoa tax paid on the same income to avoid double taxation, but the U.S. filing obligation itself does not go away.
I own a ski condo in Park City but I'm domiciled elsewhere. How many days can I spend there before Utah taxes me?+
Up to 183 days in the aggregate during the year, using Utah's majority-of-day counting rule where a day only counts if you spent more time in Utah that day than anywhere else. Cross the 183-day line while keeping a permanent place of abode (owned or leased) in Utah, and the statutory residency test applies regardless of your domicile elsewhere.
What if I'm not a U.S. citizen born in American Samoa? Can I still vote?+
People born in American Samoa are U.S. nationals, not automatically U.S. citizens, unless a parent was a U.S. citizen or they separately naturalize. This status allows a U.S. passport and mainland residency rights, but American Samoa residents, whether national or citizen, do not vote in U.S. presidential elections, and the territory's Congressional delegate is non-voting. Local territorial elections are separately administered by the American Samoa Election Office.
What form do I file if I only lived in Utah part of the year?+
Form TC-40 together with Schedule TC-40B, which apportions your income between the period you were a Utah resident and the period you were not.
How many days do I need to be in American Samoa to count as a bona fide resident?+
183 days in the tax year is the cleanest path under the federal presence test, but there are four alternatives, including 549 days across the current and two prior years with at least 60 days each year. Meeting a presence prong alone is not enough; you also need to pass the tax home test and the closer connection test, which for American Samoa often weighs matai title, extended-family (aiga) ties, and lease-based home arrangements rather than conventional homeownership.
Does Utah tax Social Security?+
Yes, at the flat rate, but a Social Security Benefits Tax Credit equal to the flat rate applied to your federally taxable Social Security largely or entirely offsets the tax for filers with modified AGI at or below roughly $54,000 single or $90,000 married filing jointly. Above those thresholds the credit phases out and more of your Social Security is effectively taxed.
