Moving from Oregon to American Samoa: Residency, Taxes, and What to Prove
Oregon's 9.9% top income tax rate becomes 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. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
Oregon uses a 200-day statutory residency threshold, while American Samoa uses 183 days. Track both thresholds separately during a transition year rather than assuming they line up.
| Factor | Oregon | American Samoa |
|---|---|---|
| Statutory Residency Test | ORS 316.027 defines a resident as anyone domiciled in Oregon (unless they meet a narrow foreign-presence exception), or anyone who is not domiciled in Oregon but maintains a permanent place of abode in Oregon and spends more than 200 days of the tax year in the state, unless they can prove the presence was only temporary or transitory. | 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. |
| Domicile Test | Oregon follows the common-law domicile standard under Or. Admin. Code §150-316-0025: your permanent home, the place you intend to return to after any temporary absence. You can maintain multiple residences but only one domicile at a time, and domicile continues until affirmatively abandoned in favor of a new one, evidenced by concrete conduct rather than stated intent alone. | 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). |
| Day Count Threshold | 200 days | 183 days |
| Any Part of a Day Rule | Oregon's 200-day statutory residency test counts aggregate days present in the state; Department of Revenue guidance and case law (see Thompson v. Dept. of Revenue) focus on the totality of ties rather than publishing a strict any-part-of-a-day rule the way California does, but any day with meaningful presence counts toward the 200-day aggregate. | 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. |
| Presumptions | 200-day rule under ORS 316.027 for non-domiciliaries who maintain a permanent Oregon place of abode: more than 200 days of presence creates statutory residency regardless of domicile, unless rebutted as temporary or transitory. | None published |
| Safe Harbors | None published | 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 |
Leaving Oregon
Oregon Department of Revenue audits are less publicized than California's but still substantive, particularly for people who sold an Oregon business or Oregon real estate near their claimed departure date. Oregon's own case law (Thompson v. Dept. of Revenue, White v. Dept. of Revenue) shows the Department looks past stated intent to continued use of Oregon utilities, insurance, and household services, and to whether the taxpayer actually took concrete steps like changing driver's license, voter registration, or filing status elsewhere.
Trailing Income
Oregon-source income, including income from an Oregon business, Oregon real property, and wages for work physically performed in Oregon, continues to be taxed to nonresidents after departure. Oregon's estate tax also continues to apply to Oregon-situs real and tangible property even after a decedent has become domiciled elsewhere, since real property is taxed where it sits regardless of the owner's domicile at death.

Enforcement Methods
Common Exit Mistakes
Establishing American Samoa Residency
| Action | Agency | Deadline |
|---|---|---|
| Register with the American Samoa Tax Office and obtain filing instructions | American Samoa Government Tax Office | before the applicable filing season begins (recent filing seasons have opened in late January) |
| Obtain a REAL ID-compliant driver's license or ID, or carry a U.S. passport | American Samoa Government | required for domestic air travel identification purposes as of May 7, 2025; territory-wide REAL ID adoption was reported at only about 16% as of the announcement |
| Register to vote in territorial elections | American Samoa Election Office | confirm current registration windows with the Election Office |
| Understand land-access limits before assuming any purchase of a primary residence | American Samoa Land Commission / Governor's Office (for any alienation of communal land) | N/A, non-natives generally cannot acquire communal land outright and must lease instead |
Declaration of Domicile
American Samoa has no sworn declaration-of-domicile filing. Bona fide residency for U.S. federal tax purposes is established through the standard section 937 factual record (presence, tax home, closer connection), while American Samoa's own tax obligations are separately determined by A.S.C.A. section 11.0403 and administered directly by the ASG Tax Office.
Homestead
American Samoa has no homestead exemption program in the mainland or Puerto Rico sense, because the underlying land-tenure system is fundamentally different: over 90% of land is communally owned by extended families (aiga) under matai leadership and cannot be individually alienated to non-Samoans without Land Commission recommendation and Governor approval, or 30 years of adverse possession. Most non-native residents establish a home through a lease rather than a fee-simple purchase, which changes what 'proof of residence' evidence looks like compared to any other U.S. jurisdiction in this guide.
Voter Registration
Register through the American Samoa Election Office (https://www.aselectionoffice.gov). Because people born in American Samoa are U.S. nationals rather than U.S. citizens (unless a parent was a U.S. citizen or they separately naturalize), American Samoa residents, whether U.S. national or citizen, do not vote in U.S. presidential elections and American Samoa's Congressional delegate is non-voting; local territorial elections are separately administered.

New Resident Tax Traps
The most distinctive trap is assuming American Samoa functions like Guam or the USVI's mirror-code systems; it does not; A.S.C.A. section 11.0403 modeling on the Internal Revenue Code does not mean identical rates or identical rules, and U.S. Government employee wages earned in American Samoa remain taxable on the U.S. return regardless of bona fide residency status, unlike ordinary private-sector American Samoa-source wages.
What Changes on Tax
Oregon Top Rate
9.9%
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
Moving from Oregon to American Samoa raises the top marginal income tax rate from about 9.9% to about 15%, an increase of roughly 5.1 percentage points.
Withholding Reciprocity
Oregon and American Samoa 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
Oregon and American Samoa both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Oregon
Capital gains: Taxed as ordinary income at the same 4.75% to 9.9% brackets, with no separate or preferential long-term capital gains rate.
Estate or inheritance tax: Oregon has an estate tax with an unusually low $1 million exemption threshold, one of the lowest in the country. Rates are graduated from 10% up to 16% on the value above $1 million. There is no separate inheritance tax.
Property tax: Statewide median effective rate is roughly 0.87%, with Portland running higher at about 1.08% and Multnomah County around 0.98%, driven by layered school district, city, county, and Metro levies. Measure 50 caps annual assessed value growth at 3% regardless of market appreciation.
Sales tax: Oregon is one of only five states with no state or local sales tax of any kind.
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.
Who This Move Applies To
Travel Nurses
In Oregon
Portland-area hospital systems are a significant travel nursing market, and Oregon's no-sales-tax status has no bearing on income tax exposure for nurses working Oregon contracts. A nurse's tax home has to be a genuine, regularly used residence with duplicated living expenses to support tax-free stipend treatment; an Oregon-domiciled nurse working travel assignments elsewhere remains an Oregon resident taxed on worldwide income unless domicile is affirmatively changed.
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.
Professional Athletes
In Oregon
The Trail Blazers are Oregon's major professional franchise. Oregon applies standard duty-day allocation to nonresident athlete income at rates up to 9.9%, among the higher jock-tax burdens nationally given Oregon's steep top bracket, though Oregon-based players avoid a second layer of sales tax that would apply in most other NBA cities.
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.
Snowbirds, Long Visitors, and RVers
In Oregon
Oregon's 200-day rule is narrower than most states' snowbird thresholds: a non-domiciliary who maintains a permanent Oregon place of abode and spends more than 200 days in the state becomes a statutory resident even without ever forming domiciliary intent. This makes Oregon less forgiving than a nine-month (roughly 274-day) presumption state for anyone splitting time with a retained Oregon home.
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.
Remote Workers
In Oregon
Oregon has no convenience-of-employer rule. A nonresident performing all their work physically outside Oregon for an Oregon-based employer is not Oregon-taxed on those wages. This matters heavily for the many Washington residents who work for Portland-based employers: wages for days physically worked in Oregon are Oregon-taxable, but days worked remotely from a Washington home office generally are not, which is the structural reason so many Portland-area workers live just across the Columbia River in Vancouver, Washington.
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.
Military
In Oregon
Oregon follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Nonresident military stationed in Oregon under orders don't become Oregon residents from the posting alone. Oregon does tax military retirement pay as ordinary income for Oregon-domiciled veterans, unlike Arizona, which fully exempts it, a distinction that matters for military retirees choosing between the two states.
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.
Airline Crew
In Oregon
Portland International Airport (PDX) hosts crew bases for Alaska Airlines and other carriers. 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, protecting Oregon-based crew flying multistate routes from Oregon taxing 100% of their income.
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.
Tools for This Move
Oregon to American Samoa FAQ
Does Oregon use the 183-day rule?+
No. Oregon's statutory day-count threshold is 200 days, not 183, and it only applies to people who are not domiciled in Oregon but who maintain a permanent Oregon place of abode. If you're Oregon-domiciled, the 200-day rule doesn't even apply; you're a resident based on domicile alone regardless of day count.
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.
Can I live in Washington and work in Portland without paying Oregon income tax?+
Only on the portion of wages for days you physically worked outside Oregon. Oregon taxes wages for days you physically worked within Oregon regardless of where you live, so a Washington resident commuting into Portland for in-office work owes Oregon tax on those workdays, while remote workdays performed from a Washington home office generally don't.
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.
Does Oregon have a sales tax?+
No. Oregon is one of only five states with no state or local sales tax at all, which is a major reason it draws cross-border shoppers from Washington and California.
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.
What's the Oregon kicker and does it depend on residency?+
The kicker is a unique Oregon mechanism that refunds excess state revenue as a tax credit when actual collections exceed the state's forecast by 2% or more. It's unrelated to your residency status; it's calculated off your prior-year Oregon tax liability.
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.
Does Oregon tax Social Security?+
No. Oregon fully exempts Social Security benefits from state income tax, though pensions and 401(k)/IRA withdrawals are generally taxed as ordinary income at rates up to 9.9%.
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.
How does Oregon prove I never actually left?+
Oregon's own case law shows the Department of Revenue looks at continued Oregon utility, insurance, cable, and household service accounts, along with whether you actually changed your driver's license, voter registration, and moved your belongings, not just what you say your intent was.
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.
