Moving from Maryland to Puerto Rico: Residency, Taxes, and What to Prove

Maryland's 6.5% (state, tax year 2026, new top bracket); county piggyback tax adds 2.25% to 3.3% on top top income tax rate becomes 33% under Puerto Rico's general individual schedule; 0% to 4% on qualifying income for holders of an Act 60 Individual Resident Investor decree in Puerto Rico. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.

Residency Tests Side by Side

Maryland and Puerto Rico 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	Maryland	Puerto Rico
Statutory Residency Test	Tax-General Article §10-101(k) and COMAR 03.04.02.01B define a statutory resident as an individual not domiciled in Maryland who nonetheless maintains a place of abode in Maryland for more than six months of the taxable year and is physically present in the state for 183 days or more during the year. Both prongs, the six-month abode and the 183-day presence, are required. Comptroller guidance clarifies this is not meant to sweep in every out-of-state owner of Maryland property: a vacation home used only occasionally, or a home used to visit family, does not create statutory residency unless the 183-day presence threshold is independently met.	Puerto Rico has no separate day-count 'statutory residency' overlay the way New York or California does. Bona fide residency is governed entirely by the federal IRC section 937 three-part 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. Hacienda applies this identical federal standard, and Form 8898 (filed with the IRS, not Hacienda) is the formal notice of becoming or ceasing to be a bona fide resident once worldwide gross income exceeds $75,000 for the year.
Domicile Test	Maryland courts define domicile as the place a person has their true, fixed, permanent home, with no present intention of leaving, and to which they intend to return whenever absent (Blount v. Boston, quoting Shenton v. Abbott). Administrative Release No. 37 states the two most important criteria are where the person actually lives and where they are registered to vote, followed by a facts-and-circumstances review of five additional factor categories: the home (ownership, location, size, value of residences), time (how and where the year is spent, retirement or business activity, travel pattern), items near and dear (sentimental possessions, family heirlooms, collections), active business involvement, and family connections (where family lives, where minor children attend school, social and religious ties). Vehicle registration, bank accounts, and safe deposit box location are also considered.	The closer connection test functions as Puerto Rico's domicile test. Treasury Regulation 1.937-1(c) weighs 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, comparing total Puerto Rico contacts against the total of U.S. and foreign contacts combined.
Day Count Threshold	183 days	183 days
Any Part of a Day Rule	Yes, explicitly. Administrative Release No. 37 defines a 'day' to mean any part of a day, with one exception: a continuous period of 24 hours or less may not be counted as more than one day, which prevents a single overnight stretch spanning midnight from being double-counted as two separate days.	Any part of a day physically present in Puerto Rico counts as a full day of Puerto Rico presence. If someone is physically present in both Puerto Rico and the mainland U.S. on the same calendar day, that day counts as a Puerto Rico day, not a U.S. day. Exceptions carve out days outside Puerto Rico for qualified inpatient medical treatment, days lost to a presidentially declared major disaster or mandatory evacuation order, and up to 30 days of business or personal travel outside both Puerto Rico and the U.S., but that 30-day rule only applies if Puerto Rico days already exceed U.S. days without it.
Presumptions	None published as a separate numeric presumption beyond the statutory 6-month-abode-plus-183-day test itself.	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 Maryland

Very high exit scrutiny (5/5)

Maryland is consistently named among the most aggressive exit-audit states, in the same tier as New York, California, New Jersey, and Connecticut. Administrative Release No. 37's own published FAQ shows how hard Maryland pushes back on claimed departures: it states plainly that someone who spent zero days in Maryland during the year, used none of its services, and paid tax elsewhere is still a Maryland resident unless they can show an actual new domicile was established, not merely that they left. Three-year job assignments, overseas J-1 visa postings, and even years spent living with family in other states have all been treated by the Comptroller's own published guidance as insufficient by themselves to break Maryland domicile.

Trailing Income

Maryland does not have a published convenience-of-the-employer rule for individual income tax. Maryland-source income, wages for work actually performed in Maryland, business income sourced to Maryland activity, and income from Maryland real or tangible property, remains taxable to a nonresident after departure. Maryland residents who work temporarily in adjacent states while their family stays in Maryland remain fully Maryland residents on that income (with a credit for tax paid to the other state), per Administrative Release No. 37's own published example.

Part-Year Filing

Maryland does not use a separate part-year form the way some states do; a taxpayer who was domiciled in Maryland for only part of the year generally files the Maryland resident return (Form 502) for the resident portion and, if there is Maryland-source income after departure, a nonresident return (Form 505) for the balance, following the same domicile-change rules used to determine when the resident period ended.

Enforcement Methods

day-count reconstruction using the any-part-of-a-day standard

voter registration and driver's license records

cross-check against the Homestead Tax Credit eligibility application

family location, where minor children attend school, and where the remainder of the family lives

vehicle registration, bank accounts, and safe deposit box location

audits triggered when a longtime resident abruptly stops filing a resident return or switches to a nonresident return

Common Exit Mistakes

Assuming a multi-year job assignment, overseas posting, or a period spent staying with friends or family in other states automatically changes domicile, when Maryland's own guidance treats none of these as sufficient without actual establishment of a new domicile

Leaving a spouse or minor children in the Maryland home while claiming to have moved, which Maryland's published FAQ treats as strong evidence Maryland remains the domicile

Continuing to hold the Homestead Tax Credit on a Maryland home after claiming nonresident status elsewhere

Not tracking the any-part-of-a-day rule carefully enough, since even brief Maryland presence counts as a full day toward the 183-day threshold

Moving abroad on a temporary or restrictive visa (such as a J-1) and assuming that satisfies the requirement to be physically present in and establish a genuine new domicile, when Maryland treats a visa that requires eventual departure as evidence a new domicile was never actually established

Establishing Puerto Rico Residency

Action	Agency	Deadline
Get a Puerto Rico driver's license	DTOP (Departamento de Transportación y Obras Públicas) via CESCO	no fixed statutory deadline; practitioners recommend doing this within 30 to 60 days to build closer-connection evidence
Register a vehicle and obtain the annual marbete decal	DTOP / CESCO Digital	marbete must be renewed annually
Register to vote	Comisión Estatal de Elecciones (CEE)	register at a regional Junta de Inscripción Permanente; no fixed arrival deadline but ahead of any election you intend to vote in
Purchase a Puerto Rico principal residence (Act 60 Individual Investor decree holders)	n/a, private real estate transaction, reported to DDEC	within 2 years of decree issuance, from an unrelated seller, held individually or in a qualifying trust, not through an LLC
File the CRIM homestead exemption on the primary residence	CRIM (Centro de Recaudación de Ingresos Municipales)	file after the home becomes the owner-occupied primary residence

Declaration of Domicile

Puerto Rico has no Florida-style sworn Declaration of Domicile filing. Bona fide residency is proven entirely through the federal section 937 factual record: a Puerto Rico driver's license, Puerto Rico voter registration, Puerto Rico bank accounts, and a CRIM homestead filing on an owner-occupied Puerto Rico home are the closest functional equivalents, and are exactly what an IRS examiner requests when reviewing a Form 8898 position.

Homestead

CRIM's homestead exemption removes $150,000 from the (outdated, 1958-based) cadastral assessed value of an owner-occupied primary residence, which zeroes out or sharply reduces property tax for many homes. Filing it also functions as evidentiary support for the closer connection test, and DDEC cross-checks it against Act 60 decree compliance for Individual Investor decree holders who are required to buy and occupy a Puerto Rico home.

Voter Registration

Register through the Comisión Estatal de Elecciones (CEE) at a regional Junta de Inscripción Permanente office or the eRE online portal: https://www.ceepur.org. Being registered to vote in Puerto Rico, and not in a state, is itself one of the significant-connection factors weighed in both the presence test's 'no significant U.S. connection' prong and the closer connection test.

New Resident Tax Traps

The single biggest trap is treating the Act 60 decree as a finish line: the decree only fixes the tax rate, it does not establish bona fide residency, which must be proven independently every year under all three section 937 prongs. The second is the 10-year built-in-gain sourcing rule on pre-move investment assets, which surprises new residents who assume the 0% capital gains rate covers appreciation that happened before they relocated.

What Changes on Tax

Maryland Top Rate

6.5% (state, tax year 2026, new top bracket); county piggyback tax adds 2.25% to 3.3% on top

Puerto Rico Top Rate

33% under Puerto Rico's general individual schedule; 0% to 4% on qualifying income for holders of an Act 60 Individual Resident Investor decree

Moving from Maryland to Puerto Rico raises the top marginal income tax rate from about 6.5% to about 33%, an increase of roughly 26.5 percentage points.

Withholding Reciprocity

Maryland and Puerto Rico 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

Maryland uses common law marital property rules and Puerto Rico is a community property state. Property acquired during marriage after the move may be characterized differently going forward, which matters for estate planning and for basis step-up on a spouse's death.

Beyond Income Tax

Maryland

Capital gains: Maryland has no separate capital gains rate. Gains are included in federal adjusted gross income and taxed as ordinary income under the combined state and county rate structure.

Estate or inheritance tax: Maryland is the only state that imposes both a state estate tax and a separate inheritance tax. The 2026 estate tax exemption is roughly $5 million, well below the much higher federal exemption, which creates a real exposure gap for estates between the state and federal thresholds. The inheritance tax applies a flat 10% to property passing to non-exempt beneficiaries; lineal heirs (spouses, children, parents, grandchildren) and, notably, siblings are exempt, which is broader than most inheritance-tax states.

Property tax: Average effective property tax rate is roughly 1.0% to 1.1%, close to the national average. The Homestead Tax Credit caps the annual growth in a principal residence's taxable assessment at 10% statewide, though individual counties can set a lower cap (Anne Arundel County caps at 2%), and requires a one-time eligibility application with the State Department of Assessments and Taxation.

Sales tax: State sales tax rate is a flat 6% with no local add-ons, so 6% is also the combined rate statewide.

Puerto Rico

Capital gains: Outside Act 60, Puerto Rico taxes long-term capital gains at a preferential rate separate from the ordinary brackets. Under an Act 60 Individual Resident Investor decree, interest, dividends, and capital gains that accrue after the person becomes a bona fide Puerto Rico resident are taxed at 0%. Gains that had already accrued on investment property before the move remain taxable under the federal 10-year built-in-gain sourcing rule in Treasury Regulation 1.937-2(f), so the 0% rate does not retroactively cover pre-move appreciation.

Maryland to Puerto Rico FAQ

I didn't spend a single day in Maryland last year, didn't use any state services, and paid taxes elsewhere. Why do I still owe Maryland tax?+

This is close to a verbatim question the Comptroller's own published guidance addresses directly: unless you intended to sever ties with Maryland and establish a new domicile elsewhere, and that intent is shown by actually establishing the new domicile, you're still considered a Maryland resident and owe Maryland tax, regardless of how little you used the state during the year. Zero days present doesn't matter if your domicile never legally changed.

If I get an Act 60 decree, am I automatically a bona fide Puerto Rico resident?+

No. The decree only sets your tax rate once you qualify; it does not establish bona fide residency. You must separately satisfy the federal section 937 presence test, tax home test, and closer connection test every single tax year, and the IRS's active Act 60 compliance campaign is built specifically around decree holders who assume the paperwork alone is proof.

My job sent me away for three years and I wasn't sure if I was coming back. Am I still a Maryland resident?+

Yes, according to Maryland's own published guidance. A job assignment, even a multi-year one with genuine uncertainty about returning, does not by itself change your domicile. Temporary absences from Maryland, for business, health, or pleasure, don't constitute a change of domicile under the standard Maryland courts apply; you would need to affirmatively establish a new domicile elsewhere with real ties, not just leave.

How many days do I actually need to spend in Puerto Rico to be safe?+

183 days is the cleanest path and satisfies the presence test on its own, but it is only one of five alternatives (there is also a 549-day/3-year test, a 90-day U.S. cap, a low-U.S.-income test, and a no-significant-U.S.-connection test). Presence alone is not enough: you also need to pass the tax home test and closer connection test, and IRS examples show taxpayers with fewer than 183 days keeping a mainland vacation home, voter registration, or family have still failed on closer connection despite meeting an alternate presence prong.

How does the any-part-of-a-day rule actually work in Maryland?+

Maryland defines a day as any part of a day for purposes of the 183-day statutory residency threshold, so a few hours in the state on a given date generally counts as a full day. The one carve-out: a single continuous 24-hour period spanning midnight cannot be counted as more than one day, which prevents double-counting an overnight stretch. Combined with the requirement of a Maryland abode maintained more than six months, this makes Maryland's day count especially unforgiving for anyone splitting time between homes.

Can I keep a house on the mainland after moving to Puerto Rico for Act 60?+

You can own one, but keeping it available as a livable home while you're not there works against you on the closer connection test, which compares your Puerto Rico ties to the total of your U.S. and foreign ties. Renting it out at fair market value with limited personal use is safer than leaving it available for your own stays; a mainland home that still functions as a family gathering place is the fact pattern IRS examiners specifically target.

I keep a vacation home in Maryland but only visit occasionally. Does that make me a resident?+

Not automatically. The Comptroller's guidance specifically addresses this: a residence used as a vacation home, or kept just to visit family and friends, does not by itself make you a Maryland resident. You'd still need to be physically present in Maryland for 183 days or more during the year for the statutory residency test to apply, so occasional visits to a lightly used vacation property generally stay under the threshold.

Does buying a home in Puerto Rico under my Act 60 decree count as proof I live there?+

It's required and helpful, but not sufficient by itself. The Individual Investor decree requires you to purchase a Puerto Rico principal residence within two years, from an unrelated seller, held personally or in a qualifying trust rather than an LLC, and DDEC does check compliance. But an unoccupied or lightly used property paired with weak day counts and continued mainland ties can still fail both the decree's residency requirement and the federal bona fide residency test.

My family stayed in Maryland while I worked temporarily in another state. Am I still taxed as a Maryland resident?+

Yes. Maryland's own published example addresses this exact situation: a resident who takes up temporary residence in another state for a job while their spouse and children remain in Maryland does not lose Maryland domicile, and the fact that family stayed behind reinforces that Maryland remains the permanent home. You would owe Maryland tax on that income, though you can generally claim a credit for tax paid to the state where you worked.

What happens if the IRS decides I wasn't really a bona fide Puerto Rico resident?+

You lose the Act 60 rate for the years in question and owe federal tax on income you treated as excluded, plus interest and penalties. The pending Karakashian v. Commissioner case shows how aggressive this can get: the IRS is seeking a 75% civil fraud penalty of roughly $5 million on top of the underlying tax for a single disputed year, arguing the taxpayer failed all three residency tests despite claiming 209 days on the island.

I moved overseas for work on a J-1 visa. Why does Maryland still tax me?+

Because a visa that legally requires you to leave the host country once your assignment ends prevents you from establishing a genuine new domicile there, according to Maryland's published guidance. A short-term, renewable work contract under a restrictive visa is treated as a temporary residence, not a domicile change, so you remain a Maryland resident and taxpayer for the duration, regardless of how long the overseas posting lasts.

Do I still owe US federal income tax on my Puerto Rico wages?+

If you are a bona fide Puerto Rico resident, Puerto Rico-source income is generally excluded from your federal return under IRC section 933, and you instead file Form 482 with Hacienda on your worldwide income. Income sourced outside Puerto Rico, such as wages from work physically performed on the mainland, is not covered by that exclusion and can still trigger a federal filing requirement.
