How to Form a Company in Puerto Rico: LLC, Corporation & Act 60 Structures

Whether you are relocating to Puerto Rico under Act 60, launching a new business on the island, or expanding an existing operation, forming a legal entity is one of the first steps you need to take. Puerto Rico offers the same entity types available on the mainland — LLCs, corporations, partnerships — but the process, tax implications, and strategic considerations differ in important waysX

This guide walks through the entity types available in Puerto Rico, the step-by-step formation process, which structures work best for Act 60 decree holders, and the common mistakes to avoid.

Entity Types Available in Puerto Rico

Limited Liability Company (LLC)

The LLC is the most popular entity type for new businesses in Puerto Rico, just as it is on the mainland. A Puerto Rico LLC provides limited liability protection for its members, flexible management structures, and pass-through taxation by default.

LLCs formed in Puerto Rico are governed by Puerto Rico's LLC Act. They can be member-managed or manager-managed, and the operating agreement gives founders significant flexibility in structuring ownership, profit distribution, and decision-making authority.

C Corporation

A Puerto Rico C corporation is a separate legal entity that files its own tax return and pays corporate income tax. For Act 60 Chapter 3 decree holders, a C corporation is often the preferred structure because the 4% fixed tax rate applies at the corporate level, and distributions to shareholders who are bona fide Puerto Rico residents are 100% tax exempt.

Partnerships

General partnerships and limited partnerships are available in Puerto Rico. Partnerships provide pass-through taxation and can be useful for joint ventures or investment structures. However, general partners face unlimited personal liability.

Sole Proprietorship

A sole proprietorship is the simplest form of business but offers no liability protection. Income is reported on the owner's personal tax return. This structure is rarely advisable for any significant business operation.

Step-by-Step Company Formation Process

Step 1: Register with the Puerto Rico Department of State

All business entities must be registered with the Puerto Rico Department of State. You will need to file articles of organization (for an LLC) or articles of incorporation (for a corporation), along with the required filing fee. The filing includes the entity name, registered agent address in Puerto Rico, and basic organizational details.

Step 2: Obtain an Employer Identification Number (EIN)

Apply for an EIN from the IRS. This is the same process as on the mainland and can be done online. The EIN is required for opening bank accounts, hiring employees, and filing tax returns.

Step 3: Register with the Puerto Rico Department of the Treasury (Hacienda)

Register your entity with Hacienda to obtain a merchant registration certificate and establish your Puerto Rico tax account. This step is essential for filing Puerto Rico corporate income tax returns and paying applicable taxes.

Step 4: Register with CRIM (Centro de Recaudación de Ingresos Municipales)

Register with CRIM for property tax purposes. Even if you do not own real property, businesses with personal property (equipment, furniture, vehicles) in Puerto Rico must register.

Step 5: Obtain a Municipal License (Patente Municipal)

Apply for a municipal business license in the municipality where your business operates. The patente municipal is an annual tax based on business volume, and the specific rates vary by municipality.

Key Differences from Mainland U.S. Entity Formation

• Separate tax system. Puerto Rico has its own tax code. PR corporations are not subject to U.S. federal income tax on Puerto Rico-source income.

• Municipal taxes. The patente municipal is unique to Puerto Rico and has no direct mainland equivalent.

• CRIM registration. Property tax registration through CRIM is a required step that does not exist in mainland formation.

• Community property. Puerto Rico is a community property jurisdiction. If you are married, your spouse may have an automatic interest in business assets.

Which Entity Type Works Best for Act 60 Decree Holders?

For most Act 60 Chapter 3 decree holders, the C corporation is the optimal structure. Here is why:

• The 4% corporate tax rate applies directly to the corporation's export service income

• 100% exemption on distributions means shareholders pay no additional Puerto Rico tax on dividends

• The combined effective rate can be as low as 4% to 4.5% when including municipal taxes

• Clean separation between the business entity and the individual decree holder

An LLC taxed as a corporation can achieve similar results. Some founders prefer the LLC structure for its operational flexibility while electing corporate taxation.

Tax Implications Summary

C Corp with Act 60: 4% corporate tax, 0% on distributions = ~4% effective rate

C Corp without Act 60: 18.5%-37.5% corporate tax + tax on distributions

LLC (pass-through): Income taxed at individual rates (0%-33%)

Timeline and Approximate Costs

Department of State filing: $150-$350, processing 5-10 business days. EIN application: Free, same day. Hacienda registration: $50-$100, 1-2 weeks. CRIM registration: $25-$50, 1-2 weeks. Municipal license: Varies by municipality. Legal fees for formation: $1,500-$5,000. Total estimated range: $2,000-$6,000. Timeline: 2-4 weeks.

Common Mistakes to Avoid

• Choosing the wrong entity type for Act 60. Pass-through entities may not optimize the 4% rate and distribution exemption.

• Forgetting CRIM registration. This is a commonly overlooked step that can result in penalties.

• Not obtaining a municipal license. Operating without a patente municipal can trigger fines.

• Ignoring community property rules. If married, your spouse may have rights to business assets.

• Using a mainland registered agent. Your registered agent must have a physical address in Puerto Rico.
