California to Puerto Rico: What Act 60 Movers Get Wrong About California Residency

When the Government Accountability Office looked at who actually used Puerto Rico’s resident investor incentive, one state led the list. Of the 2021 decree recipients, 381, or 19.9 percent, had lived in California before the move, ahead of Florida at 290, New York at 254 and Texas at 174. The same report, GAO-26-107225, found that recipients reported an average adjusted gross income of about 900,000 dollars before relocating and cut their federal tax by an average of 127,143 dollars a year, or 46 percent.

Almost everything written about this move is about that federal number. The IRS compliance campaign, the Form 8898, the three-part bona fide residency test under IRC section 937, the Karakashian petition in Tax Court. All of that is real, and all of it answers a federal question. None of it answers the question the Franchise Tax Board asks, which is whether you ever stopped being a California resident, and California’s top rate of 13.3 percent applies to capital gains exactly as it applies to wages.

People moving from California to Puerto Rico tend to treat those as one problem. They are two separate audits run by two separate agencies under two separate legal tests, and passing one tells the other very little. Our California residency guide rates the state 5 out of 5 on exit stickiness and 5 out of 5 on audit aggressiveness. Our Puerto Rico residency guide rates Puerto Rico 4 on stickiness and 5 on audit aggressiveness, which is a fair warning that on this corridor the arrival side is scrutinized as hard as the exit. This article is informational and is not legal or tax advice; work through your own facts with a qualified CPA or tax attorney.

The reason this corridor is getting attention right now is Act 38-2026, which Governor Jenniffer González-Colón signed on March 10, 2026. It extends the Individual Resident Investor program from a December 31, 2035 sunset to December 31, 2055, and it ends the 0 percent rate for new applicants. An application filed on or before December 31, 2026 falls under the prior rules, where interest, dividends and post-residency capital gains generally remain exempt through 2035. An application filed on or after January 1, 2027 falls under a 4 percent Puerto Rico tax on interest, dividends and post-residency capital gains, and 5 percent on certain pre-residency long-term gains.

The new regime adds conditions too. Applicants filing from 2027 on must show they were not Puerto Rico residents during the six years immediately before relocating. The program also requires buying a primary residence in Puerto Rico within two years of the decree and an annual charitable donation, currently 10,000 dollars, half of which must go to government-listed nonprofits working to eradicate child poverty in Puerto Rico. When Procopio reported the signing in March 2026, the law was still pending final endorsement from the Financial Oversight and Management Board, so confirm its current status with Puerto Rico counsel before building a plan around it.

Here is the part that matters for California. The deadline attaches to the date a decree application is filed with Puerto Rico. It has nothing to do with the date California considers your residency to have ended. A family that files a decree application in November, leaves the house in escrow, keeps the children in their California school through June, and treats December as the move date has met a Puerto Rico filing deadline. It has not changed its California domicile. Our California guide records the FTB’s classic trigger as a claimed move in late December followed by a January capital gain, and a statutory deadline on December 31 is likely to produce more of exactly that pattern this year.

The federal presence test is the number everyone remembers. Under section 937 you can satisfy it by being physically present in Puerto Rico at least 183 days, and there are four alternatives: 549 days across three years with at least 60 in each, no more than 90 days in the United States, no more than 3,000 dollars of U.S.-source earned income with more Puerto Rico days than U.S. days, or no significant connection to the United States at all. Presence is only one of three prongs, and you also need a Puerto Rico tax home and a closer connection to Puerto Rico than to the United States and foreign countries combined.

California uses none of that. Under Revenue and Taxation Code section 17014, a resident is anyone in California for other than a temporary or transitory purpose, or anyone domiciled in California who is outside the state for a temporary or transitory purpose. Section 17016 presumes residency after more than nine months in the state, and that presumption runs in one direction only. Spending fewer than nine months in California is not a safe harbor, and neither is spending 183 days in San Juan.

The test that decides a California exit is domicile, and FTB Publication 1031 lists what a change of domicile requires: abandonment of your prior domicile, physically moving to and residing in the new locality, and intent to remain there permanently or indefinitely as demonstrated by your actions. You can have only one domicile at a time, and you keep the old one until you acquire another. The publication also says the maintenance of a marital abode in California is a significant factor in establishing domicile in California, which is the sentence the rest of this article keeps coming back to.

Day counting does not line up either. Puerto Rico counts a day spent partly in Puerto Rico and partly in the United States as a Puerto Rico day for the presence test. California, per our dossier research, treats any presence in the state, even a few hours, as a day when it applies the nine-month presumption or the closest-connections analysis. The same Thursday flight from SJU to SFO can count as a day in both places, one for each auditor. And the one bright-line California safe harbor, the 546-day rule in section 17014(d), applies only to absences under an employment-related contract, excludes self-employed people contracting with their own entity, and fails if you keep a permanent place of abode in California. An investor living off a portfolio does not qualify for it.

An Act 60 decree fixes a tax rate once you qualify. It does not establish bona fide residency even for Puerto Rico and federal purposes, which is the first thing every practitioner writing about the IRS campaign stresses, and it carries no weight at all under California law. The FTB applies its own residency test rather than the IRS’s, the Form 8898 is filed with the IRS rather than with California, and the FTB will not issue written opinions on whether you were a California resident for a particular period, because Publication 1031 treats residency as a question of fact rather than law.

The two tests also measure different things. The federal closer connection test compares your ties to Puerto Rico against your ties to the United States and foreign countries combined. The California test asks whether you abandoned California specifically. In practice those tend to fail together, because the facts that tie you to the mainland are usually California facts: the house in Los Altos you kept furnished, the California driver’s license, the spouse who stayed, the physician and accountant you still see. But the burden is separate in each forum, and a record that is good enough to satisfy an IRS examiner has not been tested against the Publication 1031 factors until the FTB tests it.

None of this makes the move suspect. The Third Circuit said in Vento v. Director of Virgin Islands Bureau of Internal Revenue, 715 F.3d 455 (2013), in a territorial residency case, that choosing to live somewhere because its taxes are low is neither unlawful nor deceitful. What gets people in trouble is not the motive. It is a record that says one thing to Puerto Rico and another to California.

The federal side shows how expensive a thin record can get. In Karakashian v. Commissioner, a Tax Court petition filed April 27, 2026, the IRS rejected a dermatology physician’s claimed Puerto Rico bona fide residency for 2021. He claimed 209 days on the island. The IRS disputed the day count, placed his tax home and closer connection in New Jersey or Florida, and asserted a 75 percent civil fraud penalty of roughly 5 million dollars. The case is pending. The detail worth noticing is where the IRS put his tax home: in a mainland state. A federal examiner concluding that your real connections are in a particular state is describing the same fact pattern that state’s own residency auditor looks for.

Most movers assume that if California and Puerto Rico both claim them, a credit will prevent double taxation. California does allow one. Puerto Rico appears on the list in the Schedule S instructions of places whose net income taxes a California resident can credit. Read the conditions and the credit mostly disappears for an Act 60 investor.

First, the credit is for net income tax imposed by and paid to the other jurisdiction. A decree holder paying 0 percent on dividends and capital gains has paid nothing to credit. Second, a California resident can claim the credit only if the income taxed by the other state has a source within the other state under California law. Under Publication 1031, interest and dividends generally have a source where you are a resident, and the gain on a sale of stocks or bonds has a source where you are a resident at the time of the sale. If the FTB establishes that you were still a California resident, your portfolio income is California-source by definition, and there is no Puerto Rico-source income for the credit to attach to.

The nonresident side is no better. A California nonresident can claim the credit only for taxes paid to their state of residence, and only if that state is on a short list. For 2025 that list is Arizona, Guam, Oregon and Virginia. Puerto Rico is not on it, so a bona fide Puerto Rico resident with California-source income, such as rent from a California property or equity compensation earned in California, gets no California credit for Puerto Rico tax on that income.

The practical result is stark. If you lose the residency argument, California taxes the gain you realized at up to 13.3 percent and nothing offsets it. The asymmetry is the reason the California side deserves at least as much attention as the federal side, and running the numbers through a residency savings and exposure calculator before choosing a move date is worth more than any amount of decree paperwork.

Act 60 planning spends a lot of time on the federal built-in gain rule, and it should. Under Treasury Regulation 1.937-2(f), gain on securities and other investment property you owned before becoming a bona fide Puerto Rico resident stays partly sourced outside Puerto Rico for 10 years after the move, so the 0 percent rate never reached appreciation that happened in California. Act 38-2026 adds its own layer for new applicants, the 5 percent rate on certain pre-residency long-term gains.

California has no equivalent rule for stock, and that cuts both ways. Because Publication 1031 sources a stock gain to your residence at the time of the sale, California does not care when the appreciation happened. If you were genuinely a nonresident on the sale date, California taxes none of the gain, including appreciation that built up over twenty years in Palo Alto. If you were still a resident on the sale date, California taxes all of it. The entire California question on a portfolio sale collapses into one fact: which side of your residency end date the trade settled on.

That is why sale timing, not decree timing, is where California audits on this corridor concentrate. A January sale after a late-December move is the pattern our California guide flags as a classic trigger, and it is also exactly the sequence Act 38’s deadline encourages. The cleaner record is a move that is complete, with the house sold or leased, the family relocated and the license surrendered, well before the liquidity event rather than timed against it.

Other income does not follow residency at all. Publication 1031 is explicit that gain on California real estate is taxable by California even if the real estate is sold when you are a nonresident. Stock options and other equity compensation earned while you were a California resident keep a California source, apportioned by the ratio of California workdays to total workdays over the vesting period, no matter where you live when they vest or are exercised. And the leading California decision on this point, Appeals of Stephen D. Bragg, 2003-SBE-002, is a case the taxpayer won on residency and lost anyway. The Board of Equalization agreed Bragg had become an Arizona resident, then held his covenant not to compete payments from a 1988 business sale California-source, apportioned 84.05 percent of them to California, and sustained the assessments. Winning the domicile fight does not end California’s claim on California-source income.

A common Act 60 fact pattern is one spouse relocating to Puerto Rico while the other stays in California, at least for a school year. On the federal side that already weakens the closer connection test, which weighs where your family lives. On the California side it can do something more direct, because both jurisdictions are community property jurisdictions.

Publication 1031 lists Puerto Rico alongside California among the community property states and U.S. territories. It says the domicile of the spouse earning the income determines how that income is divided between spouses who file separately, and that community income includes compensation for services if the spouse earning it is domiciled in a community property state. Each spouse then reports half. For a couple where the earning spouse is domiciled in Puerto Rico and the other remains a California resident, that means half of the Puerto Rico spouse’s earnings can belong to the California spouse, and California taxes its residents on all of their income. The move can leave half of the income it was meant to protect inside California.

Separate property rules can change that result. Publication 1031 recognizes property declared separate in a valid agreement, and income from genuine separate property belongs to the spouse who owns it, though commingling can erase the separate character. That is a question for a family law and tax attorney together, not a filing-season fix. And none of it helps with the other half of the problem: a marital abode maintained in California is, in the FTB’s own words, a significant factor in establishing domicile in California. A spouse who stays behind is both an income-splitting issue and a domicile issue at the same time.

The quietest mistake on this corridor is filing nothing with California after the move. For a filed return, including a part-year Form 540NR, the FTB generally has four years from the filing date to assess. Under Revenue and Taxation Code section 19057(a), if no California return was ever filed for a year the FTB believes you were a resident, there is no statute of limitations at all. The person who files a Form 482 in Puerto Rico, a federal return claiming the section 933 exclusion, and nothing in California has left the one year most likely to be contested open indefinitely.

The move year is also where federal and California rules diverge most. Federal law offers a year-of-move exception to the tax home and closer connection tests, and as the CPA Journal summarizes it, the exception requires that you were not a Puerto Rico resident for the three prior years, had no tax home outside Puerto Rico for the final 183 days of the year, and are a bona fide resident for the three years after the move. The same article points out that there is no year-of-move exception at the state level: California treats the mover as a part-year resident and may tax income earned from January 1 through the day before the move, regardless of how the IRS treats that income.

The federal exposure window is long too. Practitioners writing about the IRS campaign report examinations concentrating on the 2017 through 2022 tax years, and the GAO found that only half of 2021 decree recipients filed a Form 8898 telling the IRS they had changed residency. The records you create in the move year have to hold up for a very long time, in front of more than one agency.

Set this against moving from California to Texas and the California analysis is identical: the same domicile test, the same Publication 1031 factors, the same sourcing rules for stock, real estate and equity compensation, the same unlimited statute for an unfiled year. What Texas does not add is a second auditor. A Texas mover has one agency to satisfy. A Puerto Rico mover has the FTB on one side and the IRS on the other, each applying its own test, and the benefit being claimed is large enough that both have shown interest in it. The Puerto Rico move can save more, and it has to be documented twice.

Set it against moving from Puerto Rico to California and the sourcing rule flips from friend to enemy. California taxes a new resident’s worldwide income starting the day residency begins, with no phase-in, and because a stock gain is sourced to your residence on the sale date, appreciation that built up during years of 0 percent Puerto Rico tax is fully taxable by California if you sell after you return. On the federal side, the year-of-move-from-Puerto-Rico exception described in the Form 8898 instructions preserves bona fide residency for the pre-move part of the year only if you were a bona fide resident for at least the two preceding tax years and kept a closer connection to Puerto Rico through the date your Puerto Rico tax home ended. Planning the exit from Puerto Rico matters as much as planning the entry.

Which is the honest summary of the corridor. The Act 60 decree, the 183-day count and the Form 8898 answer Puerto Rico’s questions and the IRS’s questions. California asks whether you abandoned your California domicile, on what date, whether your spouse came with you, and which side of that date your gains landed on. If those answers are clean, California’s sourcing rules are generous to a genuine nonresident. If they are not, California taxes the gain at up to 13.3 percent with no credit available, and the decree that made the move worthwhile does nothing to stop it.

The Mobility Map records days and nights by jurisdiction as they happen, which on this corridor serves two audits at once. The federal presence test counts Puerto Rico days and U.S. days under its own rules, and the California analysis looks at how much time you actually spent in California after your claimed move date and why. A contemporaneous record of both is far easier to defend than a reconstruction from boarding passes years later, and the IRS examinations practitioners describe reach back years.

Evidence Vault holds the documents each side will ask for. On the California side: the sale closing statement or arm’s-length lease on the California home, the DMV license surrender and vehicle registration changes, voter registration cancellation, school enrollment records for children, and the part-year Form 540NR for the move year. On the Puerto Rico side: the DTOP driver’s license, CEE voter registration, the deed on the primary residence purchased within two years, the CRIM homestead filing, the decree, and the Form 8898. Keeping the date on each one visible is what shows your California exit and your Puerto Rico arrival describe the same move.

AuditIQ surfaces the contradictions this corridor produces most often: a California driver’s license or voter registration still active after the claimed move, a W-2 or 1099 still issued to a California address, a California home that stays furnished and available, a spouse whose records remain entirely in California, and a large sale that settles within weeks of the claimed residency end date. Advisor sharing lets a California tax attorney and a Puerto Rico tax professional review the same record, which matters on a corridor where the two advisors are otherwise working from different facts.

ResidencyIQ organizes records and highlights potential exposure factors. It is not a law firm or an accounting firm and does not provide legal or tax advice; work with a qualified CPA or tax attorney on your own domicile, filings, and exposure in both jurisdictions.
