Moving from Oklahoma to American Samoa: Residency, Taxes, and What to Prove
Oklahoma's 4.5% 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
Oklahoma and American Samoa 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 | Oklahoma | American Samoa |
|---|---|---|
| Statutory Residency Test | An individual is treated as an Oklahoma resident for the year if domiciled in Oklahoma for any part of the year, or, independent of domicile, if the person maintains a place of abode in Oklahoma and is physically present in the state more than 183 days of the tax year. A part-year resident is someone domiciled in Oklahoma for less than the full 12 months; a nonresident is someone whose domicile was never in Oklahoma during the year. | 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 | Oklahoma defines domicile as the place established as a person's true, fixed, and permanent home, the place they intend to return to whenever absent. A domicile, once established, continues until a new one is actually acquired elsewhere; simply leaving the state does not by itself end Oklahoma domicile. | 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 | 183 days | 183 days |
| Any Part of a Day Rule | Oklahoma's own published guidance frames the test as spending 'more than 183 days' in the state; the OTC has not published a detailed any-part-of-a-day rule comparable to New York's, so travelers should not assume a brief pass-through is automatically excluded and should keep their own records rather than rely on an unstated exception. | 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 | None published | 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 Oklahoma
Oklahoma's residency exposure on the way out is lower-profile than the marquee high-tax states, but the OTC has real audit teeth: it has administrative garnishment authority without a court order and can issue a levy once a tax warrant is filed. A frequently cited audit trigger for departing residents is simply listing an Oklahoma address on a federal return while claiming nonresident status on the Oklahoma return, since that mismatch is an easy first-pass flag for the agency.
Trailing Income
Oklahoma taxes nonresidents on Oklahoma-source income, including wages for work physically performed in-state, income from Oklahoma real property, and gains on Oklahoma business interests, so a departed resident with rental property, a pass-through business interest, or lingering in-state work in Oklahoma still owes a nonresident return on that income even after establishing domicile elsewhere.
Part-Year Filing
Part-year and nonresident filers use Form 511-NR, which apportions Oklahoma tax based on Oklahoma-source income for the part of the year the filer was a resident plus any Oklahoma-source income earned as a nonresident. Filers who leave mid-year report Oklahoma-source income for the entire year and their worldwide income only for the resident portion.
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
Oklahoma Top Rate
4.5%
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 Oklahoma to American Samoa raises the top marginal income tax rate from about 4.5% to about 15%, an increase of roughly 10.5 percentage points.
Withholding Reciprocity
Oklahoma 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
Oklahoma and American Samoa both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Oklahoma
Capital gains: Ordinary income rates apply, except for a specific Oklahoma capital gain deduction: gains from the sale of real or tangible personal property located in Oklahoma and held at least five uninterrupted years, or from stock in an Oklahoma-headquartered company (headquartered in-state at least three years), can be fully deducted from Oklahoma taxable income on Form 561.
Estate or inheritance tax: None. Oklahoma is one of the states with no estate tax and no inheritance tax.
Property tax: Effective property tax rates are low nationally. The homestead exemption reduces a home's assessed value by $1,000 (worth roughly $75-125 a year depending on local millage), with an additional $1,000 assessed-value exemption for owners 65+ or fully disabled whose gross household income is under $25,000.
Sales tax: 4.5% state rate, one of the lower state-level rates in the country, but local option sales taxes routinely push the combined rate to around 9% on average and above 11% in some cities.
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 Oklahoma
Oklahoma has significant rural and tribal-affiliated hospital demand for traveling nurses. Oklahoma taxes nonresident wages for work physically performed in the state regardless of where the nurse's claimed tax home is, so a nurse on assignment in Oklahoma files a nonresident Form 511-NR on that income no matter what state they call home, and if the assignment plus other Oklahoma time exceeds 183 days with an in-state abode, the nurse risks being treated as an Oklahoma statutory resident for the year.
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 Oklahoma
The Oklahoma City Thunder is the state's marquee professional franchise, and Oklahoma applies duty-day apportionment to visiting NBA players' income for games and practices held in-state, standard 'jock tax' treatment. Thunder players themselves are Oklahoma residents or nonresidents like any other taxpayer and are taxed on their full salary if domiciled in Oklahoma, or on their Oklahoma duty days if not.
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 Oklahoma
Oklahoma is more often an origin state than a snowbird destination, retirees and remote workers commonly winter in Texas or Arizona while keeping an Oklahoma home. Because Oklahoma domicile persists until affirmatively abandoned, a part-year absence alone, even one that clears six months, does not sever Oklahoma residency without genuine steps to establish a new domicile elsewhere; conversely, spending more than 183 days in Oklahoma with a maintained abode there can pull a nominal nonresident back into statutory residency.
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 Oklahoma
Oklahoma has no convenience-of-the-employer rule. A remote worker's wages are sourced to where the work is physically performed, so someone living in Oklahoma and working remotely for an out-of-state employer owes Oklahoma tax on that income as an Oklahoma resident, while someone who moves away but still occasionally works from Oklahoma can trigger a nonresident filing obligation for those specific days.
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 Oklahoma
Oklahoma fully exempts military retirement pay from state income tax. Active-duty pay is taxed based on the servicemember's state of legal residence under the SCRA, and a nonresident military spouse can be exempt from Oklahoma withholding on their own income under the Military Spouses Residency Relief Act by filing Form OW-9-MSE with their employer each year they claim the exemption.
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 Oklahoma
Tulsa is home to American Airlines' largest maintenance and engineering base, but those are ground/MRO employees, not flight crew, so the federal Mobile Workforce carve-out for air carrier crew members (49 U.S.C. Sec. 40116) does not apply to them; their wages are sourced under ordinary multistate employee rules based on where they physically work, which for Tulsa-based maintenance staff is generally all in Oklahoma.
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
Oklahoma to American Samoa FAQ
I moved out of Oklahoma but my old employer still has my Oklahoma address on file. Will that cause a problem?+
It can. Oklahoma Tax Commission audit selection specifically looks for a mismatch between the address on your federal return and a nonresident claim on your Oklahoma return. If your W-2 or 1099 still shows an Oklahoma address after you've moved, update it immediately with your employer and any other payers to avoid triggering an automatic flag.
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.
Do I count as an Oklahoma resident if I spend exactly six months here?+
Oklahoma's day-count test kicks in at more than 183 days with a maintained place of abode, so exactly six months (183 days or fewer) generally falls short of that specific trigger. But domicile is independent of day count: if Oklahoma is still your true, fixed, permanent home under the domicile test, you can be a full-year resident regardless of how many days you were physically present.
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.
What form do I file if I only lived in Oklahoma part of the year?+
Form 511-NR, the Oklahoma Nonresident/Part-Year Resident return. It apportions your tax between the period you were an Oklahoma resident, when worldwide income is reportable, and the period you were a nonresident, when only Oklahoma-source income is reportable.
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.
I sold land I'd owned in Oklahoma for 20 years after moving away. Does Oklahoma still tax the gain?+
Yes, but you may not owe much. Oklahoma taxes nonresidents on gains from Oklahoma real property as Oklahoma-source income, but the state's capital gain deduction lets you fully deduct gain from Oklahoma real or tangible property held at least five uninterrupted years, which a 20-year hold clears comfortably. File Form 561-NR to claim it.
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 Oklahoma tax my military retirement pay if I retire here?+
No. Oklahoma fully exempts military retirement pay from state income tax, regardless of your age or how much you receive, in addition to exempting Social Security and Railroad Retirement benefits.
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.
My spouse is active duty stationed in Oklahoma, but I'm not from Oklahoma. Do I owe Oklahoma tax on my job here?+
Possibly not. Under the Military Spouses Residency Relief Act, if you're in Oklahoma solely because your servicemember spouse is stationed here on orders and you share the same domicile elsewhere, you can file Form OW-9-MSE with your employer to be exempt from Oklahoma withholding on your own wages. The form has to be renewed each year you claim the exemption.
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.
