Moving from Guam to Nebraska: Residency, Taxes, and What to Prove
The top income tax rate drops from 37% under the mirrored federal brackets; as low as roughly 25% of that (a 75% reduction) for up to 20 years for approved GEDA Qualifying Certificate holders in Guam to 4.55% in Nebraska. Establishing Nebraska residency correctly is what protects that benefit.
Residency Tests Side by Side
Guam and Nebraska 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 | Guam | Nebraska |
|---|---|---|
| Statutory Residency Test | Guam, like the other four territories, has no day-count statutory residency overlay of its own. Bona fide residency is governed by the federal IRC section 937 three-part test: the presence test, the tax home test, and the closer connection test, all of which must be satisfied for the same tax year. DRT applies the identical federal standard used by the IRS. | Nebraska's residency test is set directly by statute, Neb. Rev. Stat. §77-2714.01(7): a resident individual is one who is domiciled in Nebraska, or who is not domiciled in Nebraska but maintains a permanent place of abode in the state and spends in the aggregate more than six months (commonly applied as more than 183 days) of the taxable year in Nebraska. This gives Nebraska two independent paths into residency, domicile or the permanent-abode-plus-presence test, similar in structure to New York's and Missouri's statutory residency frameworks. |
| Domicile Test | Closer connection functions as Guam's domicile test under Treasury Regulation 1.937-1(c): the location of a permanent home, family, personal belongings, social/political/cultural/religious affiliations, routine banking, business activity, and the jurisdiction of a driver's license and voter registration are weighed against the total of U.S. and foreign-country contacts. Publication 570's own illustrative example uses a Guam/CNMI fact pattern (a hotel employee who splits time between the two) to show how the tax home and closer connection tests interact when someone has ties to more than one territory. | Nebraska applies the standard facts-and-circumstances domicile factors: permanent home location, driver's license and vehicle registration, voter registration, family and employment location, and financial ties. No published Nebraska regulation lists a closed set of weighted factors comparable to New York's; the Department of Revenue and courts apply the general common-law domicile test. |
| Day Count Threshold | 183 days | 183 days |
| Any Part of a Day Rule | Any part of a day physically present in Guam counts as a full presence day, and a day spent in both Guam and the mainland U.S. counts toward Guam. The standard exceptions for qualified medical treatment, presidentially declared disasters, mandatory evacuations, and a limited 30-day travel allowance apply under the Form 8898 instructions. | Nebraska's statute does not define whether a partial day counts toward the more-than-six-months threshold for non-domiciliaries maintaining a permanent Nebraska abode. No published Department of Revenue guidance sets a bright-line any-part-of-a-day standard comparable to New York's or California's, so this is treated as a facts-and-circumstances presence question rather than a strict per-day trigger. |
| Presumptions | None published | None published |
| 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 Guam
No widely published Guam-specific bona fide residency court case surfaced in research comparable to Vento (USVI) or Karakashian (Puerto Rico). The exposure runs through the same federal IRC section 937 framework that applies across all five territories: an examiner reconstructing whether someone claiming Guam residency actually met the presence, tax home, and closer connection tests, particularly for GEDA Qualifying Certificate beneficiaries whose real business operations or family life stayed on the mainland.
Trailing Income
As with the other mirror-code territories, gains on investment property owned before becoming a bona fide Guam resident are subject to a 10-year sourcing rule under Treasury Regulation 1.937-2(f) that can keep pre-move appreciation taxable outside Guam even after relocating, unless the taxpayer makes the special holding-period allocation election in Publication 570.
Part-Year Filing
A bona fide Guam resident generally files one return, Form 1040GU, with DRT on worldwide income and has no separate federal filing obligation for that year if the Guam return is properly filed and full tax paid. Someone who is not a full-year bona fide resident but has Guam-source income files a U.S. return with the IRS and attaches Form 5074 (Allocation of Individual Income Tax to Guam or the CNMI) if adjusted gross income is $50,000 or more and Guam-source gross income is $5,000 or more, to divide the tax between the jurisdictions.
Enforcement Methods
Common Exit Mistakes
Establishing Nebraska Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain a Nebraska driver's license | Nebraska Department of Motor Vehicles | within 30 days of establishing residency |
| Title and register vehicles in Nebraska | County Treasurer's office (Nebraska titles and registers vehicles at the county level) | within 30 days of establishing residency |
| Register to vote | Nebraska Secretary of State, Elections Division | 18 days before an election for mail/online registration; earlier in-person deadlines apply at the county election office; Nebraska does not offer same-day registration |
| File a homestead exemption application if income- and age/disability-eligible | County Assessor | by June 30 of the assessment year |
Declaration of Domicile
Nebraska has no formal declaration-of-domicile filing comparable to Florida's county-recorded declaration. Nebraska domicile is established through conduct: home purchase or lease, driver's license, vehicle registration, voter registration, and the pattern of actual presence measured against the statute's permanent-abode-plus-six-month test.
Homestead
Nebraska's homestead exemption reduces the taxable value of a primary residence for qualifying elderly (65+), disabled, or disabled veteran homeowners, subject to income caps set annually by the Department of Revenue. It must be applied for annually with the county assessor, generally by June 30, and because eligibility requires the property be the applicant's principal residence, the exemption is meaningful domicile evidence and a standard cross-check point in a residency dispute.
Voter Registration
Register online or by mail at least 18 days before an election, or in person at the county election office by an earlier deadline set each election cycle; Nebraska does not offer same-day or Election Day registration. https://sos.nebraska.gov/elections

New Resident Tax Traps
Nebraska taxes worldwide income from the date Nebraska residency begins, reported on the full-year Form 1040N or as a part-year filer using Nebraska Schedule III. New residents should also plan for Nebraska's above-average property tax rate (1.44% effective), which is a bigger ongoing cost driver in Nebraska than the income tax itself for many homeowners, and for county-level inheritance tax exposure on any Nebraska-situs property an heir might later inherit.
What Changes on Tax
Guam Top Rate
37% under the mirrored federal brackets; as low as roughly 25% of that (a 75% reduction) for up to 20 years for approved GEDA Qualifying Certificate holders
Nebraska Top Rate
4.55%
Moving from Guam to Nebraska drops the top marginal income tax rate from about 75% to about 4.55%, a reduction of roughly 70.45 percentage points.
Withholding Reciprocity
Guam and Nebraska 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
Guam and Nebraska both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Guam
Capital gains: Capital gains follow the same rates as the mirrored federal code; there is no separate Guam capital gains schedule. A Qualifying Certificate from the Guam Economic Development Authority (GEDA) can reduce the effective tax rate, including on qualifying business-related gains, for an approved project.
Estate or inheritance tax: Guam has no separate territorial estate or inheritance tax; federal estate tax rules apply through the mirror code framework to Guam-domiciled decedents, administered locally by DRT rather than the IRS.
Property tax: Real property tax rates run roughly 0.5% to 1% of assessed value annually, among the lowest effective property tax burdens under the U.S. flag, and Qualifying Certificate holders can receive a full real property tax exemption for up to 10 years on an approved project.
Sales tax: Guam has no general retail sales tax. Instead it imposes a 5% Business Privilege Tax (BPT, Guam's gross receipts tax) on businesses and a matching 5% use tax on imported personal goods, both of which GEDA Qualifying Certificate holders can have substantially abated.
Nebraska
Capital gains: Nebraska has no separate capital gains rate; gains flow through federal adjusted gross income into Nebraska taxable income and are taxed at the same graduated rates as ordinary income, aside from a narrow special election available to certain shareholders on the sale of stock in a Nebraska corporation held long-term.
Estate or inheritance tax: Nebraska is one of the few remaining states with an inheritance tax, administered at the county level rather than the state level. Rates and exemptions vary by the heir's relationship to the decedent: close relatives (spouses are fully exempt; children and other close family get a higher exemption and lower rate) pay less than distant relatives or unrelated heirs. LB 310 (2022) and later legislation raised exemptions and lowered rates in stages through 2025, softening what had been one of the more burdensome inheritance tax regimes in the country. Nebraska has no separate state-level estate tax.
Property tax: Effective property tax rate on owner-occupied housing runs about 1.44%, among the higher rates in the region and a persistent point of political pressure in the state. Nebraska's homestead exemption program reduces taxable value for qualifying elderly, disabled, and disabled veteran homeowners, subject to income caps that are adjusted annually.
Sales tax: State rate is 5.5%, with a statewide average combined rate (state plus local) of about 6.98%.
Who This Move Applies To
Travel Nurses
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 Nebraska
Nebraska has no statutory carve-out for travel nurses distinct from its general residency test; the federal tax-home question under IRS Publication 463 governs stipend treatment, and Nebraska's statutory permanent-abode-plus-183-day test then applies independently. Omaha's large hospital systems (Nebraska Medicine, CHI Health) draw a steady stream of travel nursing assignments, and a nurse who claims an out-of-state tax home while actually maintaining a Nebraska residence and spending more than six months in the state during the year risks Nebraska statutory residency regardless of the federal stipend question.
Professional Athletes
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 Nebraska
Nebraska has no major professional sports franchise, though the University of Nebraska's athletic programs generate significant visiting-team and visiting-official travel. Nebraska applies duty-day apportionment to nonresident athletes and entertainers who earn income from events held in the state, consistent with how most income-tax states administer the jock tax for touring and visiting performers.
Snowbirds, Long Visitors, and RVers
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 Nebraska
A Nebraska snowbird who is Nebraska-domiciled and winters in Arizona or Florida remains a Nebraska domiciliary unless they take affirmative steps to change domicile; simply spending part of the year away does not by itself end Nebraska residency. A non-domiciled owner of a Nebraska vacation or second home faces the statutory test directly: maintaining a permanent Nebraska abode and spending more than six months (roughly 183 days) in the state during the year makes them a Nebraska statutory resident regardless of where they consider their true domicile.
Remote Workers
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 Nebraska
Nebraska has no convenience-of-the-employer rule, so a genuine Nebraska resident working remotely for an out-of-state employer is taxed as a Nebraska resident regardless of employer location, and a nonresident working remotely for a Nebraska employer generally is not pulled into Nebraska tax solely because the employer is headquartered there. Omaha's status as a regional corporate hub (Berkshire Hathaway, Union Pacific, several major insurers) means a meaningful population of remote and hybrid workers whose employer is Nebraska-based but who live in Iowa or elsewhere; Nebraska's statutory abode-plus-presence test, not the employer's location, governs whether they owe Nebraska tax.
Military
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 Nebraska
Nebraska follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Nebraska remains a Nebraska domiciliary and taxpayer regardless of duty station, and Nebraska does not tax a nonresident servicemember's military pay solely because they are stationed in Nebraska under orders. Offutt Air Force Base near Omaha is the state's major installation, and a nonmilitary spouse residing in Nebraska solely due to military orders can elect the servicemember's state of legal residence under MSRRA.
Airline Crew
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 Nebraska
Federal law (49 U.S.C. §40116) limits any state's ability to tax an air carrier employee's pay to the employee's state of residence and any state where more than 50% of pay is earned. Eppley Airfield in Omaha is not a major airline crew base, so this carve-out is less frequently in play for Nebraska specifically, but it still protects any Nebraska-domiciled crew member from having their full income pulled into a duty-station state's tax.
Tools for This Move
Guam to Nebraska FAQ
Does Guam have its own separate income tax system like Puerto Rico?+
No. Guam uses a mirror code under 48 U.S.C. section 1421i, meaning it applies the U.S. Internal Revenue Code word for word with 'Guam' substituted for 'United States.' You pay the same 10% to 37% federal brackets, just to Guam's Department of Revenue and Taxation instead of the IRS, which is a fundamentally different structure from Puerto Rico's or American Samoa's independently legislated tax codes.
Does Nebraska use a 183-day rule?+
Effectively yes, but only for people who aren't Nebraska-domiciled. Nebraska statute treats you as a resident if you're domiciled in Nebraska, full stop, or if you're not domiciled in Nebraska but maintain a permanent Nebraska home and spend more than six months (in practice, more than 183 days) in the state during the year. If you're Nebraska-domiciled, the day count doesn't save you; you need to actually change your domicile.
If I get a GEDA Qualifying Certificate, do I automatically qualify as a Guam resident for tax purposes?+
No. A Qualifying Certificate sets up eligibility for a tax reduction, generally up to a 75% income tax reduction for up to 20 years in the standard category, but you must still independently satisfy the federal presence, tax home, and closer connection tests every year, and GEDA and DRT can review whether the underlying business and residency are genuine throughout the certificate term.
I moved out of Nebraska but still own the house and visit often. Am I still a resident?+
It depends which side of the domicile line you're on. If you're still Nebraska-domiciled, occasional visits don't change anything, you're still a resident regardless of day count. If you've genuinely changed your domicile elsewhere but kept the Nebraska house available and usable, you become a Nebraska statutory resident anyway if your total days in Nebraska for the year exceed roughly 183, so frequent return visits to a retained property are exactly what trips this test.
How many days do I need to spend in Guam to be a bona fide resident?+
183 days in the tax year is the cleanest path, but there are four alternatives: 549 days across the current and two prior years with at least 60 days each year, 90 days or fewer in the U.S., $3,000 or less in U.S.-source earned income with more Guam days than U.S. days, or no significant U.S. connection at all. Meeting a presence prong alone is not enough; the tax home and closer connection tests must also be satisfied.
Does Nebraska tax Social Security benefits?+
No, Nebraska fully exempts Social Security benefits from state income tax as of tax year 2024, following a multi-year phase-in of the exclusion.
I split time between Guam and the CNMI. Which one is my tax home?+
Your tax home is your regular or main place of business or employment, regardless of where you also own property or spend leisure time. The IRS's own Publication 570 example addresses this exact situation: a hotel worker employed seasonally in Guam but living the rest of the year in the CNMI was found to have a Guam tax home because that's where the regular place of business was, even though the CNMI held stronger personal and social ties.
What form do I file if I only lived in Nebraska part of the year?+
Part-year residents and nonresidents file Nebraska Form 1040N along with Nebraska Schedule III, which allocates Nebraska-source income and computes the appropriate ratio to apply to your Nebraska tax.
What tax return do I file if I'm a bona fide Guam resident?+
You generally file Form 1040GU with Guam's Department of Revenue and Taxation reporting your worldwide income, and you're not separately liable to file with or pay the IRS for that year as long as the Guam return is properly filed and the tax fully paid. If you're not a full-year bona fide resident but have Guam-source income, you file with the IRS and may need to attach Form 5074 to allocate tax between the jurisdictions.
Does Nebraska really still have an inheritance tax?+
Yes, Nebraska is one of the few remaining states with an inheritance tax, and it's collected at the county level rather than by the state. Rates and exemptions depend on how closely related the heir is to the decedent, spouses are exempt and close family gets a lower rate and higher exemption than distant relatives or unrelated heirs. Legislation in 2022 and after (LB 310 and subsequent bills) raised exemptions and cut rates in stages through 2025, making it meaningfully less burdensome than it used to be, but it hasn't been repealed.
Can I keep my mainland home after moving to Guam?+
You can own it, but keeping it available as a livable home for your own use works against you on the closer connection test, which compares your Guam ties to the total of your U.S. and foreign ties. Renting it out at fair market value with limited personal-use days is a safer pattern than leaving it available for regular stays.
Is Nebraska an aggressive state for residency audits?+
No, Nebraska is not on the short list of states practitioners and taxpayer forums consistently flag as aggressive, a list dominated by New York, California, New Jersey, Connecticut, Maryland, and Minnesota. That said, Nebraska's statutory permanent-abode-plus-183-day test is a real, objective trigger for anyone who keeps a Nebraska home after claiming to have moved.
