Why December 31, 2026 Matters: The 0% Capital Gains Deadline

If you are considering Act 60, there is a date circled on the calendar that should focus your thinking: December 31, 2026. Applications filed before this date are grandfathered at 0% tax on passive income — capital gains, dividends, and interest. Applications filed after this date lock in at 4% instead.

The difference between 0% and 4% may sound small. On real dollar amounts, it is not. And once your decree is approved, the rate is contractually locked for 15 to 30 years. There is no redo.

What Changes on December 31, 2026

Act 60 was amended to phase down the most aggressive benefits over time. The key change for new applicants:

• Before December 31, 2026: Chapter 2 Individual Resident Investor decrees receive 0% tax on capital gains, dividends, and interest earned after establishing residency.
• After December 31, 2026: New Chapter 2 applicants receive a 4% rate on the same passive income. Still highly favorable compared to mainland rates of 23.8% to 37%+, but not zero.

This is a one-time, irreversible threshold. Your filing date — not your approval date — determines which rate applies. File on December 30, 2026, and you are grandfathered at 0%. File on January 2, 2027, and you are locked at 4% for the life of your decree.

Why This Matters in Dollars

Scale this to larger portfolios and the stakes grow proportionally. On $20M in post-move gains, the difference is $800,000. On $50M, it is $2,000,000. The filing date is the single variable that determines which column you fall into.

The Application Timeline: Why You Cannot Wait

The December 31 deadline is about your filing date, not your decision date. Preparing a complete Act 60 application takes time. Rushing it at the last minute risks errors, omissions, and rejection — which could push your effective filing date past the deadline.

A properly prepared application requires:

• Entity formation: If you are filing under Chapter 3 (Export Services), you need a PR-registered business entity. Formation takes 2-4 weeks.
• Bona fide residency plan: You need a documented plan for establishing physical presence, tax home, and closer connection. See our residency test guide.
• DEDC submission: The Department of Economic Development and Commerce requires a complete application package with supporting documentation.
• Legal and CPA coordination: Your advisory team reviews entity structure, chapter alignment, and documentation before submission.
• Government processing: DEDC review and approval takes additional time beyond your filing date — but the filing date is what matters for the rate lock.

Allow 60-90 days minimum from the start of engagement to a filed application. If you are reading this in September 2026, you have roughly 90 days. That is enough time if you start now. It is not enough time if you start in November.

What Happens If You Miss the Deadline

Missing the deadline is not catastrophic. A 4% rate on passive income is still extraordinary compared to mainland rates:

• Capital gains: 4% (Act 60 post-deadline) vs. 23.8% (mainland federal + NIIT) vs. 31.8% (with California state tax)
• Dividends: 4% vs. 23.8% vs. 31.8%
• Interest: 4% vs. 40.8% vs. 53.8%

The 4% rate is still worth pursuing. But the 0% rate is unambiguously better, and it is available only to those who file before the deadline. If you are going to make the move regardless, there is no reason to accept a worse rate for 15-30 years when a few weeks of preparation could secure the better one.

The Contractual Guarantee: Once Locked, It Stays Locked

Here is the critical point that makes the deadline so urgent: your decree is a binding contract with the Puerto Rico government. The rate you lock in at filing cannot be revoked or modified unilaterally — even if Act 60 is amended again in the future, even if the program is repealed entirely.

This means:

• If you file before December 31, 2026, your 0% rate is contractually guaranteed for 15-30 years (extendable through 2055).
• If you file after December 31, 2026, your 4% rate is contractually guaranteed for the same term.
• No future legislative change can alter your locked rate. The decree is yours.

This is why the deadline matters so much. It is not a "best practice" or a "preferred window." It is a binary, irreversible threshold that determines your tax rate for decades. Once you are on one side of it, you cannot cross over.

Key Takeaways

• File before December 31, 2026: 0% on capital gains, dividends, and interest for the life of your decree.
• File after: 4% on the same income — still favorable, but $200K+ worse on typical portfolios.
• Allow 60-90 days minimum for application preparation. Starting in September means you have just enough time.
• Your filing date — not your approval date — determines your rate.
• Once locked, the rate is contractually guaranteed for 15-30 years. No future legislative change can alter it.
