How Microsoft’s Puerto Rico Structure Reduced Its Tax Rate — And What Individuals Can Do With PR Act 60

Microsoft has routed substantial IP and manufacturing through Puerto Rico for tax reasons for decades. For US individual founders, PR Act 60 offers a related (but different) legitimate benefit — with genuine relocation required.

The Microsoft Structure

Microsoft has used Puerto Rico’s favourable tax framework for decades — historically for CD/DVD manufacturing (physical fulfilment of software) and later for IP licensing. Puerto Rico is a US territory but with its own tax framework offering meaningful advantages for qualifying activities. Various IRS audits and disputes have contested aspects, but the underlying structure has been broadly successful.

The Individual Version: PR Act 60

For US individual founders, PR Act 60 (formerly Acts 20 and 22) offers something different but related:

  • Individual Investor: 0% Puerto Rico tax on qualifying capital gains and interest/dividend income arising after bona fide PR residence begins

  • Export Services: 4% corporate tax on qualifying export services performed from PR

The catch: you must become a genuine PR bona fide resident. This is not a paper residency. Physical presence (183+ days), tax home in PR, and closer connections to PR than to any other jurisdiction are all required.

Why This Works Legally for US Citizens

Puerto Rico is a US territory. US federal income tax generally does not apply to PR-source income earned by PR bona fide residents (Section 933).

Combined with Puerto Rico’s own favourable rates for qualifying activities, this creates a legitimate legal structure — one of the very few legal paths for US citizens to substantially reduce US individual income tax without renouncing citizenship.

What FTR Sees

For US-citizen entrepreneurs with meaningful capital-gain-generating businesses (SaaS about to sell, crypto investors, hedge fund principals), Puerto Rico Act 60 is often the single best legal tax planning move without leaving the US. It requires:

  • Genuine relocation (not a mailing address)

  • Ongoing physical presence

  • Real economic activity in PR (for Act 60 corporate benefits)

  • Careful timing around asset realization events

Common pitfalls: relocating AFTER a major sale (much of the gain is US-taxable); insufficient physical presence; failing bona fide residency tests; ongoing significant US business activities that create ECI.
