Puerto Rico Act 60 vs Caribbean Citizenship: Only One of Them Cuts Your Tax

The call I take most often now comes from someone already halfway into Act 60. They have a decree, or an application in progress, or a lease in Dorado — and they are tired. Tired of the day count, tired of explaining to their accountant why the family is still enrolled in a Connecticut school district. What they want to know is whether a Caribbean citizenship gets them out of it, and whether the honest version of that conversation ends in renunciation. Roughly 95% of my clients are American, so I have this conversation constantly. It rarely goes the way they expect, because the two things being compared do not do the same job. One changes a US tax bill. The other does not touch it.

Last reviewed 5 August 2026. Several figures here are statutory and dated, so confirm anything you plan to act on.

The short answer

Act 60 is the only one of these routes that changes what an American owes the IRS: 4% on qualifying export-services income and, for a complete Individual Resident Investor application filed on or before December 31, 2026, 0% on interest, dividends and post-residency capital gains — 4% for applications from January 1, 2027 under Act 38-2026. A passport from St Kitts & Nevis, Antigua & Barbuda, Grenada, Dominica or St. Lucia changes an American's federal position by nothing: the United States taxes citizens on worldwide income wherever they live, and none of the five has a US income tax treaty. Act 60 works only if you genuinely relocate and keep passing three federal residency tests every year; the Caribbean asks nothing of you, because it is not doing anything for your tax bill. The only route that ends US worldwide taxation is renunciation, which carries an exit tax and needs another nationality settled first. My recommendation: if the goal is tax, do Act 60 and do it properly. Buy the Caribbean citizenship anyway, on the insurance budget rather than the tax budget. And if renunciation is genuinely in your future, check your grandparents before you check the program brochures.

The asymmetry, stated plainly

Act 60 is a move. A passport is a document. Most versions of this decision go wrong because someone treated the two as substitutes.

Act 60 works because Puerto Rico sits inside the US system: Section 933 of the Internal Revenue Code lets a bona fide resident exclude Puerto Rico–source income from federal gross income. The decree sets the local rate; Section 933 makes the arithmetic bite. Nothing equivalent exists for a Caribbean citizen, and with the five Caribbean citizenship programs there is no treaty either, so there is no tie to break. Nor does the Foreign Earned Income Exclusion help: it shelters US$132,900 for 2026, and only earned income. Salary qualifies; capital gains, dividends, interest and rent do not — precisely the income a private client has.

The case for the Caribbean route, made properly

I want to make this case at full strength before I take it apart, because on one measure it beats Act 60 outright.

Entry is cheap by the standards of this decision. Fund routes run from US$200,000 in Dominica, on the region's shortest three-year hold, through US$230,000 in Antigua & Barbuda for one applicant or a family of four, US$235,000 in Grenada and US$240,000 in St. Lucia, to US$250,000 in St Kitts & Nevis. Approved real estate starts around US$200,000 in Dominica, where a one-bedroom at the Residences at Secret Bay is US$220,000; at a flat US$300,000 in Antigua, which Hodges Bay Resort meets exactly; and at US$325,000 in St Kitts & Nevis, the price of a fractional interest in the Four Seasons villas on Nevis.

Holding the citizenship itself asks almost nothing. Only Antigua & Barbuda attaches a presence condition — 30 days within the first five years, applied administratively while the 2026 amendment bill awaits passage.

Now the part that matters when you are comparing burdens. St Kitts & Nevis and Antigua & Barbuda levy no personal income tax on residents at all — no capital gains tax, no inheritance or gift tax. Three of the five get oversold here: Dominica taxes residents up to 35%, Grenada up to 28%, St. Lucia up to 30%. But in the two that are genuinely zero, tax residency runs on presence, generally a 183-day standard, and that is the end of the list. No decree, no annual certification, no mandated home purchase, no US$10,000 a year of compulsory giving, no sunset date, no fiscal oversight board holding the rate provisional.

So the blunt version holds: Caribbean tax residency is materially less onerous than bona fide Puerto Rico residency. Act 60 asks the same 183 days and then keeps asking. The passport buys something Act 60 never offers, too — under the Revised Treaty of Basseterre, a citizen of any of the five can land in any other OECS protocol state and receive an indefinite-stay stamp, with the right to live and work and no permit required.

Where that case collapses for an American

Every word above is true. None of it is available to you while you hold a US passport.

Caribbean tax residency is lighter than Act 60 in exactly the way a country you do not owe tax to is lighter than one you do. A US citizen who moves to Nevis, buys a house and spends 300 days a year there still files a Form 1040 reporting worldwide income, still reports every foreign account, and still owes the same federal tax on their portfolio as they did in Greenwich. The 183-day standard decides whether St Kitts taxes you. It has no bearing on whether the IRS does.

Which is why I say the thing that runs against my own commercial interest: buy the Caribbean citizenship for mobility, settlement rights and a genuine Plan B, or do not buy it. I guided more than a hundred families through these programs in 2025 alone, and not one American file in that stack was a tax play — because for a US citizen there is no such thing.

What Act 60 actually asks of you

People go looking for a Caribbean alternative because Act 60 turned out harder than it was sold to them. Bona fide residency is defined federally under Section 937 in three parts, and you must pass all three in every year you claim the benefit.

The presence test is the flexible one, with more routes through it than most people are told: 183 days in Puerto Rico during the tax year; or 549 days across the current year and the two before it with at least 60 in each; or no more than 90 days in the United States all year. The tax home test asks where your principal place of business sits. The closer connection test asks where your family is, where your homes are, where you bank, where your civic life happens. Clear the day count, keep your real life on the mainland, and you fail three years later when the examiner arrives.

Then the decree obligations: a Puerto Rico primary residence purchased within two years, a US$10,000 annual donation split between two qualifying nonprofits, and — from January 1, 2027 — a certification of six years of prior non-residency. A December 2025 GAO report counted 5,852 resident-investor decrees granted from 2012 to 2024 against only 2,236 holders filing Puerto Rico returns in 2021. Numbers like that guarantee enforcement, and it has arrived: in one case the IRS rejected a residency claim outright and asserted a 75% civil fraud penalty on a deficiency of roughly US$5 million.

There is a stability point too. Act 38-2026 rewrote the rate in March 2026, and was still awaiting final endorsement from Puerto Rico's Financial Oversight and Management Board under PROMESA as of this review. A regime a legislature can re-rate is not the same product as a country that has never levied the tax at all. That is the fairest thing I can say for the Caribbean side — and still not a reason to choose it, because the Caribbean is not offering an American a rate.

The five routes, side by side

Renouncing: the only exit, and the part people misprice

The State Department dropped the renunciation fee from US$2,350 to US$450 on April 13, 2026 — an 81% cut, and a rounding error against what matters. The real bill is the exit tax, and it reaches only a "covered expatriate": net worth of US$2 million or more (a threshold written into law in 2008 and never indexed), average annual net US income tax above US$211,000 over the prior five years for 2026, or an inability to certify five years of clean filings on Form 8854. Trip one and the IRS treats you as having sold your entire worldwide estate the day before you leave, taxing gain above a US$910,000 exclusion for 2026, with your IRA deemed fully distributed as ordinary income and no exclusion against it at all. Dying a covered expatriate also hands your US heirs a permanent bill: under Section 2801 they owe 40% on gifts and bequests above a US$19,000 annual exclusion.

Here is the piece I almost never see priced, and it is why I am wary of the "go all in on a Caribbean passport" version of this plan. Give up US domicile along with citizenship and your US estate tax exemption falls from the US$15 million per person that applies for 2026 under the One Big Beautiful Bill Act to a Form 706-NA filing threshold of US$60,000 of US-situs assets — a figure the IRS notes is not indexed for inflation, catching US real property and shares in US-incorporated companies. A non-resident alien also pays 30% withholding on the gross amount of US-source dividends, interest, rents and royalties not effectively connected with a US trade or business, and 15% of the gross price under FIRPTA on a US property sale.

Treaty relief exists for all of that. The United States holds estate and/or gift tax treaties with fifteen countries, Ireland, Italy, Canada and the United Kingdom among them — and none with the five Caribbean programs. A former American holding only a Caribbean passport, still owning a Manhattan apartment and a US brokerage account, has traded a manageable annual filing obligation for an unmanageable estate exposure. It is the most common structural mistake in this area.

The Tier A passport most Americans never check

The client I advise fastest is the one who could reach a Canadian, British or EU passport by descent. Spend your first month on your family tree rather than on program brochures: an ancestry claim costs a filing fee instead of a quarter of a million dollars, and it lands you somewhere better.

Canada eliminated its first-generation limit on citizenship by descent when Bill C-3 came into force on December 15, 2025. Anyone born abroad before that date who can trace an unbroken chain back to a Canadian-citizen grandparent or earlier ancestor became a citizen automatically by operation of law; what you apply for is proof of a citizenship you already hold, at CAD$75, against a queue running around 19 months. Ireland's grandparent-based Foreign Births Register route is fully open and busier than ever — a record 18,910 US citizens applied in 2025, against 2,064 a decade earlier. Italy went the other way: the 2025 Tajani decree capped descent at two generations, and the Constitutional Court upheld it in March 2026. These routes narrow without warning. If you qualify, file.

One caveat, because this is where the marketing overreaches. The "dual citizen from birth" carve-out from covered-expatriate status is narrower than it looks: it requires that you held the other citizenship at birth, that you remain taxed as a resident of that country, and that you spent 10 years or less of the last 15 as a US resident. An American living in Chicago who documents an Irish claim in 2026 satisfies none of that. A Tier A passport is a better landing place for someone who expatriates, not a tax instrument in itself.

Portugal deserves a note, since so many clients are already in it. The golden visa remains open through a minimum €500,000 into a CMVM-regulated fund, but the 2026 nationality law doubled the ordinary naturalisation clock to ten years from your first residence card, and Portugal's Constitutional Court held in December 2025 that applying that retroactively to pending files was unconstitutional. If you filed before the reform you keep the five-year clock, and that file is worth more than you think. If you have not, it is a decade to a passport, and the Caribbean is months.

What I actually tell people to do

One: if tax is the goal, Act 60 — and live it rather than file it. Nothing else lets a US citizen keep the passport and pay a single-digit rate on new investment gains. A complete application on or before December 31, 2026 locks the 0% regime; failing that, 4% through 2055 is still the best rate available to an American anywhere, and if your gains are mostly ahead of you it is arguably the better trade.

Two: buy the Caribbean citizenship anyway, from the insurance budget. It changes nothing about your 1040. What it buys is live-and-work rights across the Eastern Caribbean, a jurisdiction outside US politics, banking optionality, and something your children inherit. It is also the hard prerequisite for step four, and it takes months you will not have when you suddenly want it — the program comparison is where I keep the current entry points and hold periods.

Three: if renunciation is on your horizon, check your ancestry first. Irish, Italian, Canadian and British claims cost a filing fee and land you in a country holding a US estate tax treaty and somewhere real to live. Most people who qualify have never looked.

Four: do not renounce while your balance sheet is still American. The US$60,000 non-resident estate threshold and 30% gross withholding will quietly cost more than the filing obligation you were trying to escape. Restructure the US-situs exposure first, with expatriation counsel, on a runway of years.

Where does that leave the client in Dorado who started this article tired? Usually staying. Act 60 lived honestly turns out to be enough — and the Caribbean passport bought alongside it does a job they had not thought to ask for, which is the job it was always good at.

Key takeaways

• Act 60 is the only one of the two that touches a US tax bill. A Caribbean passport changes an American's federal position by nothing: the US taxes citizens on worldwide income, and none of the five programs holds a US income tax treaty.
• Act 60 demands genuine relocation — three federal tests every year, plus a Puerto Rico primary residence within two years and a US$10,000 annual donation. The closer-connection test is what fails people.
• Caribbean tax residency really is lighter than bona fide Puerto Rico residency: the same 183-day standard in St Kitts & Nevis or Antigua & Barbuda, then nothing else. That lightness is only worth something once you have left the US tax system.
• Renunciation is the only exit and it is priced — a mark-to-market exit tax above a US$910,000 exclusion for covered expatriates, an IRA deemed fully distributed as ordinary income, and a 40% Section 2801 tax on whatever US heirs later receive.
• Do not renounce into a Caribbean-only position while holding US assets. US-situs assets above US$60,000 become estate-taxable with no treaty relief, where Ireland, Italy, Canada and the UK all hold US estate or gift tax treaties.

Frequently asked questions

Does a Caribbean passport reduce US taxes if I move to the island full time? No. The United States taxes citizens on worldwide income regardless of where they live or what other nationality they hold, and none of the five programs has a US income tax treaty. Since St Kitts & Nevis levies no personal income tax, there is no second claim to relieve in the first place. Your US liability is identical.

Is Puerto Rico's Act 60 still worth doing in 2026? For the right person, yes. A complete Individual Resident Investor application filed on or before December 31, 2026 keeps the 0% regime on interest, dividends and post-residency capital gains; applications from January 1, 2027 get a flat 4% under Act 38-2026, with benefits to December 31, 2055. It remains the only route by which a US citizen keeps the passport and pays a single-digit rate on new gains.

Is Caribbean tax residency easier to maintain than Act 60? Yes, meaningfully. St Kitts & Nevis and Antigua & Barbuda determine tax residency on presence, generally 183 days, and ask nothing further. Act 60 asks the same day count and adds a tax-home test, a closer-connection test, a property purchase and US$10,000 a year in giving. The catch is that this only matters once you are no longer a US citizen.

Should I claim citizenship by descent instead of buying a Caribbean passport before renouncing? If you can, yes. Irish, Italian, Canadian and British ancestral claims typically cost a filing fee rather than US$200,000 and up, and those countries hold estate and/or gift tax treaties with the United States where the Caribbean states do not. Check eligibility before you price a purchase — descent routes narrow without warning, as Italy's 2025 two-generation cap showed.

What does renouncing US citizenship actually cost? The consular fee is US$450 as of April 13, 2026, down from US$2,350. The real cost is the exit tax, which reaches only covered expatriates: net worth of US$2 million or more, average annual net US income tax above US$211,000 for 2026, or a failed five-year compliance certification. Covered status means a deemed sale of your worldwide estate above a US$910,000 exclusion, an IRA deemed fully distributed as ordinary income, and a lasting 40% Section 2801 exposure for US heirs.
