Puerto Rico Act 60: 0% Capital Gains for US Citizens

Today we're going to talk about the single most powerful tax optimization tool available to US citizens who want to legally pay 0% on capital gains without renouncing their passport: Puerto Rico Act 60 tax benefits.

Here's the situation. The United States taxes its citizens on worldwide income, no matter where they live. If you're an American entrepreneur sitting in Lisbon or Dubai, the IRS still wants its cut. The only way to permanently escape the US federal tax net is to formally renounce your citizenship, which triggers the US exit tax, a mark-to-market regime that treats all your worldwide assets as if they were sold the day before you leave. For founders holding highly appreciated equity, that bill alone makes expatriation financially prohibitive.

But there's an extraordinary loophole built into the US tax code itself: Puerto Rico. As a US territory, Puerto Rico offers something no foreign country can. Under IRC Section 933, bona fide residents of Puerto Rico can exclude Puerto Rico-source income from their US federal gross income. And under Act 60 (the consolidated version of the old Act 20 and Act 22), qualifying residents can achieve a 0% tax rate on capital gains and a 4% corporate tax rate on export service income, all while keeping their US passport firmly in their pocket.

Let's break it down.

How Act 60 Works: Export Services and Individual Investor Acts Combined

Act 60 is really two programs merged into one legislative package. Originally enacted as separate statutes, Act 20 (Export Services) and Act 22 (Individual Investors) were consolidated in 2019 into the Puerto Rico Incentives Code, which everyone just calls Act 60.

Chapter 2 (Individual Resident Investor) covers passive income. This is the provision that shields capital gains, dividends, and interest from taxation for qualifying individuals.

Chapter 3 (Export Services) covers active business income. This provision offers a flat 4% corporate income tax rate for businesses that export services from Puerto Rico to clients located outside the island.

The combination is what makes Puerto Rico Act 60 tax benefits so attractive. You can run your export services business at a 4% corporate rate, extract the profits as dividends at 0% (dividends paid from eligible export service income are fully exempt from Puerto Rico tax), and simultaneously grow your investment portfolio with 0% capital gains on assets acquired after establishing residency.

On the mainland, by comparison, a C corporation pays 21% at the corporate level, and then the shareholder pays up to 23.8% on dividends (20% capital gains rate plus 3.8% Net Investment Income Tax). The combined effective rate can easily exceed 37%. The math speaks for itself.

The 0% Capital Gains Rate and the 4% Corporate Rate

Let's talk numbers, because this is where Puerto Rico tax incentives really stand apart.

For individuals with an Act 60 decree obtained on or before December 31, 2026, the rates are:

• Capital gains on assets acquired after establishing residency: 0%
• Dividends and interest sourced to Puerto Rico: 0%
• Pre-move capital gains sold after 10 years of residency: 5% (Puerto Rico tax only, no federal)
• Corporate income tax on eligible export services: 4%
• Dividends paid from export service income to the resident owner: 0%

Now, here's the critical update. Puerto Rico recently enacted Act 38-2026, which represents a significant shift. For anyone submitting a decree application on or after January 1, 2027, the 0% rate on passive income is replaced by a 4% preferential rate. The program's expiration date is also extended from 2035 to 2055.

So if you apply before the end of 2026, you're grandfathered into the legacy 0% structure (expiring 2035). If you apply after that, you get 4% but it's locked in through 2055. The law also lets existing legacy decree holders voluntarily swap to the new framework, trading their 0% rate (expiring 2035) for a 4% rate guaranteed for an additional twenty years.

Even at 4%, the math is still extraordinarily favorable. A mainland US resident in a high-tax state faces an aggregate effective rate on capital gains that can push well beyond 30%. A flat 4% locked in for three decades is still a different universe.

(hint: the window to lock in 0% closes December 31, 2026, and that deadline is not negotiable)

The 10-Year Pre-Move Appreciation Trap

This is the part that most people get wrong, and it's the part that the IRS is most aggressively enforcing.

Here's the core rule: IRC Section 933 only protects Puerto Rico-source income from federal taxation. If income is classified as US-source, it's fully taxable by the IRS regardless of where you live.

For capital gains, the sourcing follows the seller's tax home at the time of sale under IRC Section 865(a). So gains on assets you acquire after establishing your tax home in Puerto Rico are Puerto Rico-source. Simple enough.

But the US tax code contains a specific anti-abuse provision (IRC Section 937(b)(2)) designed to prevent exactly what you're thinking: "I'll just move to Puerto Rico and sell my $50 million stock portfolio tax-free." This is the 10-year lookback rule.

Here's how it works:

1. If you sell a pre-move asset within 10 years of establishing Puerto Rico residency, the portion of gain that accrued before the move is classified as US-source income. Full federal capital gains tax applies to that pre-move appreciation. No Act 60 protection.

2. If you hold the asset for more than 10 years after establishing residency, the pre-move appreciation loses its US-source character. Puerto Rico then taxes that pre-move gain at a preferential 5% rate, and the federal government steps aside entirely (thanks to a specific carve-out in IRC Section 865(g)(3)).

Let's use an example. Say John from Austin owns $10 million in publicly traded stock with a cost basis of $2 million. He moves to Puerto Rico in 2026. If he sells in 2030 (four years in), the $8 million of pre-move gain is US-source. He owes full federal capital gains tax, potentially 23.8% plus any state clawback. The post-move appreciation (whatever the stock gained between the move date and 2030) gets the 0% Act 60 rate.

If John waits until 2037 (eleven years in), the entire gain becomes Puerto Rico-source. He pays 5% to Puerto Rico on the pre-move portion and 0% on the post-move appreciation. Zero to the IRS.

Now, for publicly traded securities and crypto, you can elect a mark-to-market valuation on the exact date you establish residency. This cleanly separates pre-move from post-move appreciation.

For illiquid assets like private equity, closely held businesses, or unappraised real estate, the situation gets painful. The regulations typically require a pro-rata temporal allocation. Total gain divided by total days held, multiplied by pre-move days. This linear method ignores when the actual value was created. If your startup was worth almost nothing for five years in California and then exploded in value after you moved to Puerto Rico, the IRS still drags roughly 62.5% of the gain backward and classifies it as US-source if you held it 5 out of 8 total years.

For illiquid assets, getting independent 409A valuations or structured appraisals on the precise date of relocation is not optional. It's the only way to defend against pro-rata distortions during an audit.

Bona Fide Residency Test: Presence, Tax Home, and Closer Connection

Now I know what you're thinking. "I'll just get the decree, rent an apartment in San Juan, and fly back to Miami every weekend." The IRS knows you're thinking that too.

A common misconception is that holding an Act 60 decree automatically shields you from federal tax. It does not. The IRS imposes its own rigid, multi-pronged residency tests under IRC Section 937(a), and you must satisfy all three prongs simultaneously for the entire taxable year. Fail any single one, and your worldwide income is retroactively subject to standard US federal taxation for that year.

Physical Presence Test: While commonly summarized as a "183-day rule," the regulations actually provide five alternative pathways:

1. Present in Puerto Rico for at least 183 days during the tax year
2. Present for 549 days across the current year and two prior years (with at least 60 days each year)
3. No more than 90 days of physical presence in the mainland US during the tax year
4. No more than $3,000 in US-source earned income, and present in Puerto Rico more days than in the US
5. No "significant connection" to the US (no permanent home, no spouse/minor children residing there, no active voter registration)

This is distinct from the substantial presence test that applies to foreign nationals. That test determines whether an alien is a US tax resident. For a US citizen moving to Puerto Rico, the controlling statute is the physical presence test under IRC Section 937(a)(1).

Tax Home Test: Your tax home must be in Puerto Rico for the entire taxable year. "Tax home" means the general area of your regular or principal place of business, not where you sleep. If you claim to live in Puerto Rico but maintain an office, a primary business headquarters, or a workspace in a mainland state where you routinely conduct substantial executive functions, the IRS will argue your tax home is still in the US.

Closer Connection Test: This is the most qualitative and subjective of the three. The IRS evaluates whether your aggregate personal, social, and economic ties to Puerto Rico outweigh your ties to the mainland. They look at everything: where your permanent home is, where your family lives, where your personal belongings are, where your bank accounts are, where you have social and cultural memberships, where your driver's license and voter registration are.

Retaining a large estate in Florida while renting a modest apartment in Puerto Rico, or sending your kids to private school in New York while claiming San Juan as home, are viewed as fatal structural flaws. The IRS uses passport stamps, flight manifests, credit card geolocations, and even cellular network data to triangulate your location on any given day. Complete integration into the Puerto Rican community (local charitable giving, social memberships, transfer of personal infrastructure) is practically mandatory to survive an audit.

And one more thing: if you have worldwide gross income exceeding $75,000 and you move to or from Puerto Rico, you must file IRS Form 8898. Failure to file carries an automatic $1,000 penalty and keeps the statute of limitations open.

Source-of-Income Rules for Service Businesses

If you're running a service business under Chapter 3 of Act 60 (the export services provision), the source-of-income rules are the make-or-break detail.

To qualify for the 4% corporate rate, your business must provide eligible services from a physical base in Puerto Rico to clients located entirely outside the island. The range of eligible activities is broad: consulting, digital marketing, software development, financial advisory, R&D, engineering, cloud computing, telemedicine, and more.

But here's the critical point. Under federal sourcing principles, compensation for personal services is sourced to the physical location where the services are performed. Your income is Puerto Rico-source (and thus eligible for the 4% rate) only to the extent you are physically on the island while performing the work.

Let's say Sarah runs a digital marketing agency from San Juan under an Act 60 decree. She flies to New York for fourteen days to negotiate client contracts and conduct workshops. The income attributable to those fourteen days of work performed in New York is US-source income, subject to standard federal taxation. Act 60 doesn't protect it.

The IRS is aggressive here. During audits, examiners demand daily work logs, flight records, IP address access logs, and billing metadata to bifurcate service income precisely based on where the work was performed. Contracts should specify that service delivery emanates from Puerto Rico, and billing records must reflect this reality.

Beyond the corporate rate, Chapter 3 provides a second benefit: dividends distributed from eligible export service income to shareholders are 100% exempt from Puerto Rico taxation. So the entity pays 4% on net profits, and the owner extracts the remaining 96% tax-free. Compare that to a mainland C corporation where profits are taxed at 21% federally and dividends are taxed again at up to 23.8% at the individual level.

To prevent shell corporations, Act 60 enforces economic substance requirements. Companies generating over $3 million in annual gross revenue must employ at least one full-time, Puerto Rico-based employee in a core operational role.

GILTI and Subpart F Still Apply to Foreign Corporations

This is where many people get tripped up. A bona fide resident of Puerto Rico is still a US citizen and still a "United States person" under federal tax law. If you directly own a company in Dubai or the Cayman Islands, that entity is classified as a Controlled Foreign Corporation (CFC), and you're subject to GILTI and Subpart F inclusions on the company's profits.

However, there's a specific carve-out under IRC Section 957(c). A US citizen who is a bona fide Puerto Rico resident is excluded from being treated as a "United States shareholder," but only with respect to a corporation organized under Puerto Rico law, and only if that Puerto Rican corporation derives less than 25% of its gross income from US effectively connected income.

In other words, if you route ownership through a properly structured Puerto Rican corporation rather than holding foreign entities directly, the CFC rules don't apply to you as the Puerto Rico resident owner. The Puerto Rican entity can own foreign subsidiaries classified as disregarded entities, and the global income flows up into the Puerto Rican parent without triggering GILTI or Subpart F. When those profits are distributed to you as dividends, they're Puerto Rico-source income, taxable at 0% (or 4% post-2026).

This is an advanced strategy that requires meticulous structuring. If a mainland US resident co-owns more than 50% of the same Puerto Rican entity, the whole thing is treated as a standard CFC and the mainland investor is fully subject to GILTI inclusions. The exemption is exclusively for the individual who physically lives on the island and satisfies the IRC Section 937(a) residency tests.

If you're considering this type of architecture, you're firmly in the territory of working with qualified cross-border tax advisors. This is not a DIY situation.

The Lifestyle Trade-off: Cost of Living, Hurricane Risk, and Infrastructure

The tax math can be extraordinary. But a physical relocation to Puerto Rico comes with real, tangible trade-offs that act as a hidden "cost" offsetting the fiscal benefits.

Power grid instability: This is the most critical operational risk. After Hurricanes Irma, Maria (2017), and Fiona (2022), Puerto Rico's electric grid remains fragile. Blackouts, rolling brownouts, and voltage fluctuations are routine. If you're running an export services business that depends on connectivity and uptime, you'll need to budget for commercial-grade solar arrays, battery storage, and diesel generator backups. This is a significant upfront capital expenditure.

The Jones Act premium: Under the Merchant Marine Act of 1920, all goods shipped by water between US ports must travel on US-flagged, US-built, US-crewed vessels. Because Puerto Rico imports heavily from the mainland, this creates a 20% to 40% markup on delivered goods, groceries, vehicles, construction materials, and commercial equipment. Your cost of living is higher than the mainland equivalent.

Skilled labor scarcity: Persistent outmigration of professionals to the mainland over the past decade has tightened the local labor pool. Scaling corporate operations or developing real estate takes longer and costs more.

Hurricane vulnerability: This is a real, recurring environmental risk. Impact-grade construction, flood-aware site selection, and comprehensive property insurance are necessities, not luxuries.

Healthcare infrastructure: While high-net-worth residents can access private care facilities in San Juan, the broader healthcare system faces chronic underfunding. For individuals with complex medical needs, this is often the deciding factor against relocation.

None of this is to say the move doesn't make sense. It's to say that the "tropical paradise" narrative hides real costs. A responsible analysis models the total cost, including infrastructure resilience, Jones Act premiums, insurance, and the operational overhead of maintaining physical presence on the island.

Who Act 60 Actually Works For (and Who It Doesn't)

Act 60 is strategically optimal for specific, well-defined profiles:

• High-margin service entrepreneurs: Consultants, software developers, financial advisors, and digital marketers who can genuinely detach their operations from the mainland. Shift your tax home to the island, physically perform your work there, and you lock in the 4% corporate rate with tax-free dividend distributions
• Traders and investors building post-move portfolios: If you're planning to acquire new assets, day-trade liquid securities, or launch new crypto ventures after establishing residency, the 10-year lookback doesn't apply. Post-move capital gains compound at 0% (or 4% post-2026) from day one
• Global planners utilizing the GILTI exemption: Ultra-high-net-worth operators who can structure Puerto Rican holding entities under IRC Section 957(c) to legally bypass Subpart F and GILTI on international subsidiaries

And the profiles where Act 60 doesn't work:

• Holders of massive pre-move appreciation: If you're sitting on $50 million of unrealized gains in US private equity or early-stage crypto, moving to Puerto Rico doesn't wash those gains clean. The 10-year lookback ensures pre-move appreciation stays in the US tax net for a decade. Liquidating within that window triggers full federal taxation, making the physical move pointless from a tax perspective
• "Paper" residents who can't actually move their lives: If your family, social ties, primary business operations, and daily routine remain anchored to the mainland, the IRS will challenge your residency. The 2021 enforcement campaign and the GAO's push for better data sharing between the IRS and Puerto Rican authorities mean that paper residency strategies face serious scrutiny and tax liability
• Anyone unwilling to commit to genuine relocation: Act 60 demands a holistic life transition. PR driver's license, local voter registration, local banking, children enrolled in local schools, furniture shipped to the island. Half measures are fatal in an audit

Puerto Rico Act 60 remains, unambiguously, the single most powerful domestic tax optimization vehicle available to US citizens. But it rewards those who commit fully and structure properly, while punishing those who treat it as a paperwork exercise. The opportunities are still significant, particularly for entrepreneurs willing to work with qualified advisors to navigate the residency tests, source-of-income rules, and the rapidly closing 0% grandfathering window before December 31, 2026.
