When an individual relocates to Puerto Rico to take advantage of Act 60 benefits, the focus is naturally on satisfying the federal bona fide residency test under IRC §937(a) and complying with the DDEC decree requirements. But there is a third front that many relocators underestimate: the tax authority in the state they are leaving.
High-tax states—including New York, California, Connecticut, New Jersey, and Massachusetts—aggressively audit taxpayers who claim to have changed their domicile, particularly when the move is to a jurisdiction with dramatically lower taxes. Puerto Rico, with its near-zero rates on qualifying income under Act 60, is precisely the kind of destination that draws scrutiny.
State Domicile vs. Federal Residency
State domicile and federal bona fide residency are related but distinct legal concepts. Federal residency under §937(a) is determined by the three-part test (presence, tax home, closer connection). State domicile, by contrast, is generally a subjective, intent-based inquiry: a person’s domicile is the place they consider their true, fixed, and permanent home—the place to which they intend to return whenever absent.
The practical overlap is significant. Many of the factors relevant to the federal closer connection test—location of home, family, personal belongings, driver’s license, voter registration, banking, social ties—are the same factors states examine in a domicile audit. But the legal standards are not identical, and a favorable result under one framework does not guarantee a favorable result under the other.
What States Look For
State domicile audits typically focus on five categories of evidence:
Home. Does the individual still maintain a home in the former state? Is it furnished and available for use? Have they sold, rented, or vacated it? States pay close attention to individuals who claim to have moved but retain a usable dwelling in the state.
Time. How many days did the individual spend in the former state after the claimed date of departure? Some states, notably New York, apply a statutory residency test under which an individual who maintains a permanent place of abode in the state and spends more than 183 days there in a taxable year is treated as a statutory resident—regardless of domicile.
Active ties. Does the individual still have a driver’s license, voter registration, bank accounts, club memberships, or professional affiliations in the former state? Has the individual changed these ties to Puerto Rico?
Business and employment. Does the individual continue to work in the former state, maintain an office there, or have clients and business relationships centered there?
Family. Do the individual’s spouse and children continue to reside in the former state?
The Problem of Partial Moves
The most common failure pattern is the partial move: the individual relocates to Puerto Rico, obtains an Act 60 decree, and begins claiming tax benefits, but does not fully sever ties to the former state. The mainland home is kept “just in case.” The spouse remains in the former state for school reasons. The driver’s license is not updated. Banking remains on the mainland. Social and professional activities continue largely as before.
This pattern is vulnerable on both fronts. The former state can argue that the individual never actually changed domicile. And the IRS can argue that the individual has a closer connection to the United States than to Puerto Rico. The result can be taxation by both the former state and the federal government on income the individual believed was exempt.
State-Specific Considerations
New York applies both a domicile test and a statutory residency test. An individual who maintains a “permanent place of abode” in New York and spends more than 183 days in the state is a statutory resident, even if domiciled elsewhere. New York’s definition of “permanent place of abode” is broad and has been litigated extensively. For individuals relocating to Puerto Rico, ensuring they do not trigger New York statutory residency requires both vacating the New York dwelling and limiting days of presence in the state.
California uses a “safe harbor” presumption: an individual who is domiciled in California is presumed to remain a California resident until they demonstrate both absence from the state for other than a temporary or transitory purpose and establishment of domicile elsewhere. California’s Franchise Tax Board has a dedicated audit team for high-income departure cases.
Other high-tax states apply similar frameworks with varying degrees of aggressiveness. The common thread is that the burden of proof in a state departure audit generally falls on the taxpayer.
Coordinating Federal and State Compliance
Because the factors examined in a state domicile audit overlap substantially with those relevant to the federal closer connection test, the compliance strategy should be integrated. Steps that satisfy the federal closer connection test—selling or vacating the mainland home, changing driver’s license and voter registration to Puerto Rico, relocating banking and professional services, establishing community ties in Puerto Rico—simultaneously strengthen the state departure position.
The reverse is also true. Steps that a state auditor would view as evidence of continued domicile in the former state—keeping the home, maintaining memberships, retaining a state driver’s license—also undermine the federal residency claim.
Planning the departure should address both frameworks simultaneously. The objective is a clean, complete, and well-documented transition that is defensible on all fronts.
Documentation
State auditors will request documentation. The records that support a state departure case are substantially the same as those needed for federal residency compliance: day-count logs, travel records, evidence of the new Puerto Rico home, cancellation or disposal of the former state dwelling, change-of-address confirmations, new Puerto Rico driver’s license, voter registration cancellation in the former state and registration in Puerto Rico, and records of community involvement in Puerto Rico.
The earlier this documentation is assembled and the more contemporaneous it is, the stronger the position in any audit.
