How corporate tax works in Puerto Rico
Puerto Rico's ordinary corporate regime imposes an 18.5% normal tax and a graduated additional surtax that can raise the combined marginal rate to 37.5%. The effective result depends on taxable income, deductions, credits and entity classification.
A corporation, an LLC taxed as a corporation and a pass-through entity are not interchangeable. Partnerships and other pass-through structures can shift the tax computation to the owners rather than using the corporation table.
Foreign corporations doing business in Puerto Rico can face local tax on Puerto Rico-source income or income effectively connected with the Puerto Rico business. Act 154 and related sourcing rules require special care for large groups.
Act 60 provides preferential regimes for qualifying export services, manufacturing, tourism, finance and other activities. A 4% headline rate is an incentive result, not the ordinary rate for every Puerto Rico company.
The U.S. federal treatment is separate. A Puerto Rico company is not automatically outside federal tax, withholding, information reporting or transfer-pricing rules.

Watch out for
- The 37.5% figure is a top marginal combined rate, not a flat tax on every dollar of corporate profit.
- A tax decree does not replace substance. The activity, employees, assets, customers and revenue sourcing must fit the incentive claimed.
- Entity classification, related-party payments, transfer pricing, withholding and U.S. information reporting can matter more than the local headline rate.
- A company managed from Puerto Rico can create local tax and filing exposure even when it was incorporated elsewhere.
