Moving from Guam to New Jersey: 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 10.75% in New Jersey. Establishing New Jersey residency correctly is what protects that benefit.
Residency Tests Side by Side
Guam and New Jersey 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 | New Jersey |
|---|---|---|
| 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. | N.J.S.A. 54A:1-2(m): a resident is anyone domiciled in New Jersey, or anyone who is not domiciled in New Jersey but maintains a permanent place of abode there and spends, in the aggregate, more than 183 days of the taxable year in the state. Meeting either prong, domicile or the 183-day-plus-abode combination, makes a person a full resident taxed on worldwide income. |
| 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. | New Jersey courts treat domicile as a person's true, fixed, permanent home, the place they intend to return to whenever absent. Once established, domicile is presumed to continue at the same location until a taxpayer proves both an intent to abandon it and the establishment of a new one elsewhere. Courts weigh home ownership and use, driver's license and vehicle registration, bank and brokerage account location, school enrollment for children, employment, and how quickly the taxpayer returned to New Jersey after the claimed move. |
| 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. | Generally yes, presence in New Jersey for any part of a day counts toward the 183-day count, consistent with how New York and Connecticut apply the rule, though New Jersey's published guidance is less granular than New York's regulation on specific travel-day exceptions. |
| Presumptions | None published | Domicile is presumed to continue at its established location until the taxpayer affirmatively proves both abandonment of the old domicile and acquisition of a new one; this presumption was decisive against the taxpayers in Samuelsson v. Director. |
| 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 New Jersey Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain a New Jersey driver's license and register any vehicle | Motor Vehicle Commission | within 60 days of becoming a resident |
| Register to vote | NJ Division of Elections / County Commissioner of Registration | at least 21 days before an election |
Declaration of Domicile
New Jersey has no formal declaration-of-domicile filing comparable to Florida's county-recorded process. Domicile is established purely through conduct, and the same fact pattern used to prove a move (home purchase, MVC registration, voter registration, time actually spent) is exactly what a later audit re-examines.
Homestead
The ANCHOR program is a property tax rebate for both owners and renters, income-capped, and available only for a principal residence occupied as of a set date each base year. It is not an asset-protection homestead exemption in the Florida sense, but enrolling in it on a New Jersey home is documented evidence the property is your principal residence, and continuing to claim it on a New Jersey home while filing a nonresident return elsewhere is a direct contradiction auditors look for.
Voter Registration
Register online, by mail, or in person through the County Commissioner of Registration or the MVC at least 21 days before an election; New Jersey requires 30 days of county residency before Election Day. https://www.nj.gov/state/elections/voter-registration.shtml
Vehicle Registration Deadline
60 days
New Resident Tax Traps
Full New Jersey taxation of worldwide income begins on the date domicile or statutory residency starts; a mid-year move is split between NJ-1040 and NJ-1040NR. Retirees moving in should note the retirement income exclusion disappears entirely, not partially, once total income exceeds $150,000, which is a hard planning cliff rather than a gradual phase-out.
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
New Jersey Top Rate
10.75%
Moving from Guam to New Jersey drops the top marginal income tax rate from about 75% to about 10.75%, a reduction of roughly 64.25 percentage points.
Withholding Reciprocity
Guam and New Jersey 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 New Jersey 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.
New Jersey
Capital gains: Capital gains have no preferential rate and are taxed as ordinary income under the Gross Income Tax's Category A (net gains from disposition of property), at the same graduated rates as wages.
Estate or inheritance tax: New Jersey repealed its estate tax effective January 1, 2018. It still has an inheritance tax, but spouses, domestic partners, children, grandchildren, parents, and stepchildren (Class A beneficiaries) are fully exempt. Siblings and children-in-law (Class C) get a partial exemption and pay reduced rates; unrelated beneficiaries and distant relatives (Class D) are taxed at rates up to 16%.
Property tax: New Jersey has the highest effective property tax burden in the nation, averaging roughly 2.23% of home value. The ANCHOR program provides an income-capped rebate to both homeowners and renters whose principal residence is in New Jersey, functioning as informal domicile evidence even though it is a rebate, not a true exemption.
Sales tax: Statewide flat rate of 6.625% with no general local add-on; certain Urban Enterprise Zones charge a reduced rate on some purchases.
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 New Jersey
The same statutory test applies to a travel nurse as to any other worker: a nurse who is not domiciled in New Jersey but keeps a New Jersey apartment for an extended assignment and accumulates more than 183 days in the state becomes a statutory resident taxed on worldwide income. Nurses claiming a tax home in a no-income-tax state while actually living in and never visiting that claimed home face the same tax-home challenges under federal rules that they would in any other high-scrutiny state.
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 New Jersey
New Jersey taxes nonresident professional athletes on New Jersey-source income using duty-day apportionment for games played at MetLife Stadium and the Prudential Center. This catches every visiting team plus the home rosters of the New York Giants, New York Jets, and New Jersey Devils, all three of which are legally domiciled and play their home games in New Jersey despite the Giants' and Jets' branding.
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 New Jersey
Keeping a New Jersey house while wintering in Florida creates two separate exposures: the 183-day statutory residency test for income tax, and the domicile-continuity presumption that governs New Jersey's inheritance tax. Samuelsson v. Director shows courts look past a Florida driver's license and school enrollment to whether the New Jersey home was ever sold or rented and whether the family returned quickly, so a snowbird pattern that never lets go of the New Jersey house is high risk under both tests.
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 New Jersey
New Jersey enacted its own convenience of the employer rule in 2023 (P.L. 2023, c.125, retroactive to January 1, 2023), which taxes a nonresident who telecommutes for a New Jersey employer for their own convenience, rather than the employer's necessity, as if the work were performed in New Jersey. The rule is reciprocal by design and currently reaches residents of Delaware, Nebraska, and New York, the states with their own convenience rules; Pennsylvania residents are excluded because of the separate PA-NJ reciprocal agreement, and Connecticut residents are excluded because Connecticut's rule is itself reciprocal.
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 New Jersey
New Jersey follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember or accompanying spouse domiciled elsewhere who is in New Jersey solely on military orders does not become a New Jersey domiciliary, and the servicemember's military pay is not taxed by New Jersey if they remain domiciled in another state.
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 New Jersey
Federal law (49 U.S.C. §40116) limits states to taxing air carrier employee compensation only in the employee's state of residence and any state where they earn more than 50% of their pay. This is directly relevant to crew based at Newark Liberty International Airport, a major hub, who are domiciled outside New Jersey.
Tools for This Move
Guam to New Jersey 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 New Jersey really have an exit tax when I sell my house and move to Florida?+
Not in the sense most people mean. There is no separate New Jersey tax charged for the act of leaving. What exists is a withholding requirement, GIT/REP, collected at the closing table when a nonresident sells New Jersey real estate, equal to the greater of 2% of the sale price or the estimated gain at the top 10.75% rate. That withholding is credited against your actual New Jersey tax bill when you file, and if you still resided in New Jersey when the deed transferred, it does not apply at all.
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.
If I sell my New Jersey home before I move, does that end my New Jersey tax exposure?+
Selling the home removes it as evidence, but it does not automatically end exposure. Samuelsson v. Director shows New Jersey courts presume domicile continues at its last established location until a taxpayer proves both intent to abandon it and establishment of a new one; in that case, never selling the New Jersey house was decisive against the taxpayers. Selling the house, not renewing New Jersey vehicle registration, and not returning quickly all matter more than any single document like a Florida driver's license.
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.
My employer is based in New Jersey but I work remotely from New York, do I owe New Jersey tax?+
Not under New Jersey's own convenience of the employer rule, at least not for that reason. New Jersey's 2023 convenience rule only reaches nonresidents from states that impose their own convenience rule on New Jersey residents, currently Delaware, Nebraska, and New York. So a New York resident telecommuting for a New Jersey employer can actually be pulled the other direction, by New York's convenience rule, not New Jersey's, depending on which state's rule the facts trigger first.
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.
Does claiming the ANCHOR benefit on my New Jersey home hurt me if I say I've moved out of state?+
It can. ANCHOR requires the property to be your principal residence as of the program's set date, so continuing to receive it on a New Jersey home while filing a nonresident return and claiming domicile elsewhere is a direct contradiction the Division of Taxation can cross-check. If you've genuinely moved, stopping ANCHOR enrollment on the New Jersey property is one of the administrative steps that supports your new residency claim.
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.
Can I still visit my house in New Jersey after I move to Florida without it hurting my residency claim?+
Occasional visits are lower risk than a pattern of extended stays, but the details matter more than the visit count alone. In Samuelsson, the taxpayers' return to New Jersey within about a year, combined with never selling the house, was enough for the Tax Court to find domicile had never been abandoned. A short visit to a sold or rented-out former home is far safer than repeated stays in a house you still own and could move back into at any time.
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.
If I keep my New Jersey day count under exactly 183 days, am I safe?+
Staying under 183 days protects you from the statutory residency test, but not necessarily from a domicile challenge if you never formally abandoned New Jersey as your true home, and it does nothing for New Jersey's separate inheritance tax exposure, which turns on domicile, not day counts. Many taxpayers assume the 183-day rule is the whole test; it is only one of two independent ways New Jersey can claim you as a resident.

Moving the other direction is a different fact pattern, not a mirror image: exit risk and establishment mechanics both flip.
