LLC vs. Corporation in Puerto Rico: Which Entity Should You Form?

By Hans Riefkohl, Riefkohl Law • August 2026

The choice looks familiar — the rules are not

If you have formed companies on the mainland, the Puerto Rico menu looks reassuringly familiar: limited liability companies, corporations, partnerships. Both LLCs and corporations are creatures of the same statute — the General Corporations Act of 2009 (Act 164-2009), with LLCs governed by its Chapter XIX — and both give you limited liability, a registered agent requirement, and a filing with the Puerto Rico Department of State.

But the decision does not work the way mainland intuition says it should, for one big reason: Puerto Rico flips the default tax treatment of LLCs. Founders who assume "LLC = pass-through" — the U.S. federal default — routinely discover at tax time that their Puerto Rico LLC has been a corporation all along. This guide walks through the real differences and how to choose.

Liability and governance: mostly a tie, with a flexibility edge to the LLC

Both entities shield owners from business debts when properly maintained. The practical differences are in how they run:

• LLC: governed by an operating agreement. Member-managed or manager-managed, flexible profit splits, no required board, officers, or annual minutes. Best when you want contractual freedom among a small group of owners.
• Corporation: governed by bylaws with a board of directors and officers. More formality — shareholder and board actions, minutes, stock records — but a structure investors, banks, and (eventually) buyers understand instantly. Corporations can also issue preferred stock and qualify for equity-compensation structures more cleanly.

One local overlay applies to both: Puerto Rico is a community-property jurisdiction. If you are married, your spouse may hold an automatic interest in the equity unless capitulaciones (a prenuptial agreement) or other planning says otherwise. Build the cap table with that in mind.

The tax classification trap: Puerto Rico LLCs are corporations by default

This is the single most important — and most misunderstood — difference.

• Puerto Rico income tax: under Section 1010.01 of the Puerto Rico Internal Revenue Code of 2011, an LLC is taxed as a corporation by default. Pass-through treatment exists, but only by election filed with Hacienda. Since Act 52-2022, electing entities fall under the Code's unified pass-through entity regime (effective for taxable years beginning after December 31, 2022): the entity files an informative return and the income flows through to the owners.
• U.S. federal tax: for federal purposes, Puerto Rico entities are treated as foreign eligible entities under the check-the-box rules. A Puerto Rico LLC whose members all have limited liability also defaults to corporate treatment federally; changing that requires a Form 8832 election.

The two elections are separate. Nothing aligns them automatically, and a mismatch — pass-through in one system, corporation in the other — can create double-tax exposure, phantom income, or reporting traps for owners who split time between Puerto Rico and the mainland. If you want your Puerto Rico LLC to behave like a mainland LLC, that outcome must be built, on both filings, on time. It is not the default anywhere.

The tax numbers at a glance

• Corporate rates (PR): a regular corporation (or an LLC taxed as one) pays Puerto Rico corporate income tax at graduated rates from 18.5% up to 37.5%.
• Pass-through: with a valid election, income flows to the owners and is taxed at individual rates of up to 33% — plus self-employment-style contributions where applicable.
• With an Act 60 export-services decree: the decree entity pays a fixed 4% on eligible export-services income, and distributions of that income to shareholders who are bona fide Puerto Rico residents are 100% exempt from Puerto Rico tax. This is what makes the corporate form (or an LLC deliberately kept under corporate treatment) the standard Act 60 structure.

Act 60 fit: why decree holders usually pick corporate treatment

For an Act 60 export-services business, the 4% rate applies at the entity level and the dividend exemption applies at the shareholder level — so the classic structure is a corporation, or an LLC that simply keeps its default corporate treatment. A pass-through election generally works against an export-services decree holder, because it trades the 4%-plus-exempt-dividend combination for individual rates. The residency side matters just as much as the entity side: the shareholder exemption assumes you are a bona fide resident of Puerto Rico, tested every year.

For businesses without a decree — local operating companies, real-estate holders, professional practices — the pass-through election is often the better answer, keeping profits out of the 18.5%–37.5% corporate brackets. The right choice follows the tax profile, not the label.

Formation: same five steps for both

1. Department of State filing. Certificate of formation for an LLC (filing fee $250) or certificate of incorporation for a corporation (fees start around $150 and scale with authorized capital). Both require a registered agent with a physical Puerto Rico address.
2. EIN from the IRS — same process as the mainland, free, online.
3. Hacienda / SURI registration — the Merchant Registration Certificate and your Puerto Rico tax account. Classification elections are made here, on deadline.
4. CRIM registration — required for personal-property tax even if you own no real estate (equipment, furniture, vehicles).
5. Patente municipal — the municipal license tax on gross receipts, generally up to 0.5% for most businesses (1.5% for financial businesses), at rates set by each municipality.

Plan on two to four weeks end to end, plus legal fees; skipping CRIM or the patente is the most common (and most avoidable) source of penalties for new entities.

Ongoing compliance: the corporation reports, the LLC pays

• Corporation: an annual report to the Department of State by April 15 each year — $150 fee, officer and agent details, business-volume disclosure, and financial statements (GAAP-prepared below $3 million in volume; audited by a Puerto Rico-licensed CPA once volume exceeds $3 million).
• LLC: no annual report — just a flat $250 annual fee to the Department of State by the same date, with basic identifying information.

Both must keep the registered agent current, renew the patente, and file the applicable Hacienda returns (corporate return, or the pass-through informative return plus owner returns if an election is in place).

So which should you form?

• Act 60 export-services business: corporation — or an LLC left under its default corporate treatment. Do not casually elect pass-through onto a decree structure.
• Local operating business or professional practice without a decree: usually an LLC with a timely pass-through election on the Hacienda side (and a coordinated federal election if owners have U.S. filing exposure).
• Startups seeking outside investors or stock compensation: corporation, for the familiar governance and equity mechanics.
• Holding real estate or family assets: typically an LLC for flexibility — with the classification thought through before the first deed transfers, and coordinated with your estate plan if you hold an Act 60 decree.

In every case the entity type is only half the decision. The other half — the one mainland instinct gets wrong — is the pair of classification elections. Choose both on purpose.
