Moving from Florida to Guam: Residency, Taxes, and What to Prove

Florida's 0% top income tax rate becomes 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. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.

Residency Tests Side by Side

Florida does not use a simple day-count threshold; it applies a facts-and-circumstances test instead. Guam's statutory residency test uses a 183-day threshold.

FactorFloridaGuam
Statutory Residency TestNone. Because Florida imposes no personal income tax, it has no statutory day-count residency test, no 'permanent place of abode plus 183 days' rule, and no state tax return that turns on residency status. Florida residency status matters legally for homestead, probate/domicile, and asset-protection law, not for an income-tax trigger.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.
Domicile TestFlorida common law and Fla. Stat. § 222.17 define domicile as the place where a person maintains a permanent home with the present intent to remain indefinitely and to return whenever absent. There is no published multi-factor weighting test the way New York or California use; Florida courts and the probate/homestead context look at physical presence, a declaration of domicile, voter registration, driver's license, homestead filing, and where the person actually spends time, but no state revenue agency runs a residency-factor audit because there is no income tax to trigger one.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.
Day Count ThresholdNo fixed threshold183 days
Any Part of a Day RuleNot applicable; Florida has no day-count residency test of its own. Florida day counts only matter for the OTHER state's statutory residency test when someone claims Florida domicile but keeps a home and spends significant time in a high-tax origin state.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.

Leaving Florida

Moderate exit scrutiny (1/5)

Florida itself does not audit anyone leaving for income-tax purposes, because it never taxed their income to begin with. The real exit risk when someone leaves Florida is homestead exemption fraud exposure: county property appraisers actively cross-check driver's license, voter registration, and out-of-state tax filings, and a person who keeps claiming the Florida homestead exemption after establishing residency (or filing a resident return) elsewhere can be assessed back taxes plus penalties and a lien, per Fla. Stat. § 196.161.

Trailing Income

Florida does not tax deferred compensation, stock options, or business income after a resident leaves, because it never taxed it in the first place. There is nothing for Florida to claw back; the only 'trailing' exposure is the homestead exemption clawback described above if the exemption is not timely removed.

Part-Year Filing

Not applicable. Florida has no individual income tax return, so there is no part-year or final-year individual filing. Anyone leaving Florida only needs to notify the county property appraiser to remove the homestead exemption and, if applicable, file a portability request if buying a new Florida home was not part of the plan.

Enforcement Methods

property appraiser homestead cross-check against DMV and voter rolls
out-of-state resident tax return matching (via the taxpayer's new home state, not Florida)
neighbor/whistleblower tips to county homestead fraud investigation units

Common Exit Mistakes

keeping the homestead exemption active on a Florida property after establishing residency and filing as a resident elsewhere, which triggers back taxes, a 50% penalty, and 15% annual interest under Fla. Stat. § 196.161
assuming Florida's lack of income tax means there is nothing to unwind administratively when the real exposure sits with the destination state's own residency audit

Declaration of Domicile

Guam has no standalone sworn declaration-of-domicile filing. Bona fide residency is established through the same federal section 937 factual record used across the territories: a Guam driver's license, Guam voter registration, Guam banking, and, where applicable, GEDA Qualifying Certificate compliance records showing genuine local business operations.

Homestead

Guam does not have a distinct homestead exemption program comparable to Florida's or Puerto Rico's CRIM exemption; the territory's advantage is instead its low baseline real property tax rate (roughly 0.5% to 1% of assessed value), and Qualifying Certificate holders can receive a full real property tax exemption on an approved project for up to 10 years.

Voter Registration

Register at the Guam Election Commission office, through a volunteer registrar, at a village mayor's office, or online through the GEC portal: https://gec.guam.gov/register/. In-person registration must generally be completed at least 10 business days before an election.

Vehicle Registration Deadline

New Resident Tax Traps

The most common trap is treating Qualifying Certificate approval as self-executing rather than a benefit that depends on maintaining real, ongoing investment and employment commitments plus genuine bona fide residency; GEDA and DRT can review compliance throughout the certificate term, not just at approval. A second trap, highlighted in Publication 570's own worked example, is splitting time between Guam and the CNMI without a clear tax home, which can jeopardize the closer connection analysis for both territories at once.

What Changes on Tax

Florida Top Rate

0%

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

Moving from Florida to Guam raises the top marginal income tax rate from about 0% to about 75%, an increase of roughly 75 percentage points.

Withholding Reciprocity

Florida and Guam 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

Florida and Guam both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.

Beyond Income Tax

Florida

Capital gains: Not taxed. Florida has no personal income tax, so there is no separate capital gains treatment to plan around at the state level; only federal capital gains tax applies once you are a bona fide Florida resident.

Estate or inheritance tax: None. Florida repealed its estate tax when the federal state death tax credit was phased out and has no separate inheritance tax; only the federal estate tax (currently applying above the federal exemption) can apply to a Florida domiciliary's estate.

Property tax: Average effective rate is about 0.86% statewide, but the Save Our Homes cap limits annual assessed-value growth on homesteaded property to the lesser of 3% or the CPI change (2.7% for 2026), and up to $500,000 of that accumulated benefit is portable to a new Florida homestead within two years of leaving the old one.

Sales tax: 6% state rate; counties may add a discretionary surtax of roughly 0.5% to 2%, producing a combined average of about 7% depending on county.

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.

Who This Move Applies To

Travel Nurses

In Florida

Florida is the most common 'tax home' state travel nurses claim to receive tax-free stipends, but IRS and state auditors have disallowed Florida tax-home claims for nurses who kept a Florida address on paper while actually living year-round in Ohio or another assignment-state rental and never returning to Florida. To hold up, the nurse needs to actually maintain and return to the Florida home between assignments, keep paying for it continuously, and hold Florida driver's license, voter registration, and vehicle registration, not just a mailing address.

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.

Professional Athletes

In Florida

Florida is home to the Miami Heat, Miami Dolphins, Tampa Bay Buccaneers, Tampa Bay Lightning, Florida Panthers, Orlando Magic, Miami Marlins, and Tampa Bay Rays. Players on these teams owe zero state tax on the roughly half of duty days spent in Florida, but every state jock tax on duty days in taxing states (California, New York, etc.) still applies in full, and because Florida has no income tax, there is no Florida credit to offset those away-state bills, unlike a player based in a state that both taxes and grants an out-of-state tax credit.

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.

Snowbirds, Long Visitors, and RVers

In Florida

Florida itself places no day-count cap on how long a part-year resident can be in-state; the exposure runs the other direction; the origin state (New York, Connecticut, New Jersey) is the one counting days and evaluating whether the Florida home is a genuine primary residence or a seasonal one. A Florida-domiciled snowbird who spends more than 183 days in New York, with a permanent place of abode there, can still be taxed as a New York statutory resident despite the Florida homestead and driver's license.

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.

Remote Workers

In Florida

Florida has no convenience-of-the-employer rule and nothing to reciprocate, since it has no income tax to source wages against. The risk for a remote worker moving to Florida is entirely on the origin-state side: if the employer is based in New York and treats the employee as still NY-sourced under NY's convenience rule, the worker can owe New York tax on Florida-earned wages regardless of Florida residency.

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.

Military

In Florida

Florida follows the federal Servicemembers Civil Relief Act (SCRA) and Military Spouses Residency Relief Act (MSRRA): a servicemember's home-of-record state of legal residence does not change solely due to military orders stationing them in Florida, and a spouse can generally elect the servicemember's domicile state under MSRRA. Because Florida has no income tax, choosing Florida as home-of-record eliminates state income tax on military pay entirely, which is why Florida is a common home-of-record choice among active-duty service members.

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.

Airline Crew

In Florida

Federal law (49 U.S.C. § 40116) restricts states from taxing air carrier employees' wages except by their state of residence and, in limited cases, the state where they earn more than 50% of their pay. Because Florida has no income tax, crew members domiciled in Florida owe no state tax on their airline wages regardless of how their duty time is split, which is why Florida (along with Texas) is a common domicile choice for pilots and flight attendants based in Miami, Fort Lauderdale, or Orlando.

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.

Florida to Guam FAQ

If I get a Florida driver's license and file a Declaration of Domicile, is my New York tax residency automatically over?+

No. New York evaluates domicile and statutory residency independently of any paperwork filed in Florida. A Declaration of Domicile and Florida license are supporting evidence, but New York's Nonresident Audit Guidelines weigh where your home, business, family, and time actually are; if you still spend more than 183 days in New York with a place there to stay, you can be taxed as a New York statutory resident regardless of your Florida filings.

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.

Do I have to file a Florida tax return once I move here?+

No. Florida has no personal income tax, so there is no individual return to file, part-year or otherwise. The filings that matter in Florida are the Declaration of Domicile with your county clerk, your homestead exemption application with the county property appraiser (due March 1), and DMV/voter registration, not anything with the Florida Department of Revenue.

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.

How can I prove I actually live in Florida if I keep an apartment back home too?+

Build a file that mirrors what an auditor from your old state will ask for: a Florida homestead exemption (which itself requires proof you don't claim residency-based tax status elsewhere), driver's license and voter registration at the Florida address, a day-count log corroborated by credit card and travel records showing more time in Florida than in the old state, and utility bills showing the Florida home is actually used, not just owned.

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.

I'm a travel nurse claiming Florida as my tax home but I've barely been there this year. Is that a problem?+

Yes. Auditors have specifically disallowed Florida tax-home claims for nurses who kept a Florida address on paper while actually living full-time in an assignment-state rental and never returning. To hold up, you need to keep paying for and periodically returning to the Florida home, and hold Florida driver's license, voter registration, and vehicle registration there, not just a mailing address.

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.

How often can I go back and visit family in New York without messing up my Florida residency?+

There's no Florida-side limit; the New York side is what counts your days. If you maintain a permanent place of abode in New York (even a relative's home you can stay in) and spend more than 183 days there in a calendar year, including any part of a day, New York can tax you as a statutory resident regardless of your Florida domicile. Track every New York day, including short visits, arrival, and departure days.

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 filing a Declaration of Domicile in Florida count as proof I abandoned my old state?+

It's one data point, not proof by itself. Florida's Declaration of Domicile under Fla. Stat. § 222.17 is a sworn statement recorded with the county clerk and is commonly cited in residency audits as supporting evidence, but a high-tax origin state will weigh it against where you actually spend time, where your family lives, and where your business and financial life are centered before conceding the domicile change.

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.
