Puerto Rico's Trusted ACT 60 Law Firm

Michael Zierenberg is great! Super solid and dependable. He will honor their commitments and deliver.

His consultations are always thorough, and they both understand the complexities and nuances in their domain.

Would definitely recommend.

Working with Michael Zierenberg on my Act 60 transition was one of the best decisions I’ve made for my financial future. His deep knowledge of Puerto Rico’s tax incentive laws, attention to detail, and strategic guidance made the entire process smooth and stress-free. His professionalism and responsiveness gave me confidence at every step, and I highly recommend him to anyone considering Act 60.

Michael has been outstanding to work with. He is extremely responsive any time I need him, and follows up regularly and persistently to get the job done. He has an absolute expert in all-things PR tax law and Act 60. Highly recommend!

Zierenberg Group LLC is not just another consulting firm — it is a high-performance advisory practice built on integrity, precision, and regulatory depth. At the center of this firm is Michael Zierenberg, one of the most knowledgeable attorneys in Puerto Rico when it comes to Act 60, tax incentives, and corporate structuring.

What truly sets this firm apart is Michael’s firsthand experience as a member of the government’s Act 60 Regulatory Team, where he helped draft, interpret, and enforce critical provisions of the Puerto Rico Incentives Code. Few professionals in the private sector bring this level of institutional insight, making Michael an unparalleled asset to individuals and businesses relocating under Act 60.

I’ve worked with Michael for over three years, and I can confidently say he’s one of the most responsive and knowledgeable attorneys I’ve ever dealt with. His expertise in Act 60 and Puerto Rico law is unmatched, and he always takes the time to explain things clearly.

What really sets Michael apart is his communication. He returns calls and texts promptly, even during times most others wouldn’t. There was even a time he responded to a question of mine while traveling on his honeymoon, something I’d never expect, but it speaks volumes about his commitment to his clients.

Michael and his team have been nothing but fantastic. Michael is super on top of it. Any questions we have they answer immediately. He takes his work and his reputation very seriously and that shows in everything that Michael and his team do. We are very fortunate to have found him, and would highly recommend him for anyone looking to get Act60 Status or move their business to PR.

Michael and the team were thoughtful and incredibly helpful throughout the entire process of moving my business to Puerto Rico. I worked with them on multiple business applications, and they were helpful at every step.

They helped me avoid some easy-to-miss mistakes that could have created issues down the line. We spent time talking through different scenarios and what would actually allow us to grow over time.

They also went far beyond the scope of what they were hired to do. When unrelated legal questions came up in the business, Michael jumped in and helped, no hesitation, even when it had nothing to do with our engagement. It felt like working with a trusted advisor.

Before I chose them, I spoke to three of their past clients. Each conversation was candid and detailed. These were serious people who had worked closely with the firm, and they all shared a view that the team is sharp, honest, and will stand by you. I almost hired another firm before I realized their references were not real clients.
