Puerto Rico’s Act 60 offers a compelling tax incentive for U.S. citizens willing to relocate—but many participants underestimate how fiercely former states, especially California and New York, will fight to retain their tax base. Even when Act 60 participants pass the federal presence test, state tax authorities may still claim jurisdiction, leading to aggressive audits and costly litigation.
Federal Residency ≠ State Residency
To benefit from Act 60, individuals must qualify as bona fide residents of Puerto Rico under IRC §937, which includes the well-known presence, tax home, and closer connection tests. Satisfying these federal requirements can shield Puerto Rico-sourced income from U.S. federal taxation.
However, state tax residency is determined independently. States are not bound by the IRC’s definitions, and their criteria—rooted in domicile, lifestyle, and subjective “facts and circumstances”—often diverge sharply from the federal framework. This disconnect creates legal grey areas that states are increasingly exploiting.
💡 Think you’re no longer a California or New York resident because you spend 183+ days in Puerto Rico? Think again. Your “residency” could still be up for debate.
Why States Are Turning Up the Heat
High-income earners fleeing to Puerto Rico represent billions in lost tax revenue. In response, state tax departments are building robust residency enforcement units and investing in technology and staff to track former residents.
- California has ramped up audits and collected $85 million from residency cases in 2023 alone.
- New York’s Department of Taxation and Finance recovers over $200 million annually through its aggressive audit program, which includes a specialized residency unit.
As the IRS has no authority to dictate how a state defines its residents, you can pass all federal tests and still be on the hook for California or New York income taxes—sometimes for years after you move.
How States Use the Residency Gap to Their Advantage
New York and California, in particular, exploit the tension between domicile and physical presence. As detailed in our prior newsletter (“Navigating the Presence Test”), New York uses a strict statutory framework, while California leans heavily on subjective lifestyle indicators. Here’s how this creates friction:
| Federal IRS (IRC §937) | State (CA/NY) |
| 183+ days in PR → safe harbor | 183+ days outside CA/NY ≠ guaranteed nonresidency |
| Tax home test looks at where work is based | CA/NY consider family, property, and business ties |
| Closer connection judged by mailing address, assets, voting, etc. | CA/NY may scrutinize where your dog lives, where you shop, or where your doctor is |
| IRS audits presence by passport stamps, tax filings | States dig into gym memberships, Instagram posts, and Amazon shipments |
Case Study: California’s Expansive Reach
In one recent case, a former tech executive moved to Puerto Rico, passed the federal presence and tax home tests, and filed Puerto Rico returns. Yet California argued he was still a resident based on:
- His children’s continued enrollment in California private schools
- Retention of a Silicon Valley home
- Continued board positions at California-based companies
- Frequent return trips, even if under 183 days
The state asserted that despite physical absence, his “domicile” remained in California and taxed him accordingly. The taxpayer ultimately settled for over $1 million.
Strategic Takeaways for Act 60 Participants
You’ve already learned how to track your days and sever ties based on presence tests. But to truly defend against state audits, you must go deeper:
✅ Understand Domicile vs. Presence
Leaving a state physically is not enough—you must abandon domicile, which requires not just moving to Puerto Rico but proving the move is permanent and indefinite.
✅ Exit with Intention (and Documentation)
Include an official “Declaration of Domicile” when you move. Change your estate plan, healthcare providers, insurance agents, and even pet registrations to Puerto Rico.
✅ Audit-Proof Your Story
Create a consistent narrative across all touchpoints: social media, shipping addresses, business dealings, and personal habits. States look for inconsistencies.
✅ Hire Dual-Qualified Professionals
Work with tax advisors who understand both the federal presence rules and state residency traps, especially those familiar with California’s FTB and New York’s residency audit playbook.
Final Word: Don’t Get Caught Between Two Systems
There’s a dangerous misconception that passing the federal presence test immunizes you from other tax risk. State tax authorities don’t care what the IRS thinks—and their audits can reach back several years, resulting in penalties, interest, and legal battles.
Relocating under Act 60 must be approached with a clear understanding of both federal and state rules—and the landmines where they conflict. With proper planning and diligent execution, you can defend your new Puerto Rican residency status and protect your hard-earned tax savings.
