Self-employed in Puerto Rico: SURI, IVU, patente municipal and Social Security taxes

Working for yourself has real benefits: you set your own hours, choose your clients, and decide how to grow. But it also comes with responsibilities that many people don't find out about until they already owe fines. The good news is that you can get organized from the start and avoid surprises.

The first thing you need to do is register as a merchant in SURI, Hacienda's online portal (hacienda.pr.gov). SURI stands for Sistema Unificado de Rentas Internas (Unified Internal Revenue System). When you register, you receive a Certificado de Registro de Comerciante (Merchant Registration Certificate), which is the official document that allows you to operate. Without it, you could be fined if Hacienda audits you.

Once you're registered, you need to understand the IVU — Impuesto sobre Ventas y Uso (Sales and Use Tax) — which in Puerto Rico is a combined 11.5% (10.5% state + 1% municipal). If you sell physical products or certain services, you must charge your customers the IVU, keep that money separate, and send it to Hacienda through monthly returns. Note: business-to-business (B2B) services and certain designated professional services have different rules. Check with Hacienda or an accountant to find out whether your type of work is subject to the IVU.

In addition to Hacienda, you must pay the patente municipal (municipal business license tax) to your local government. This is a tax based on your business's total gross sales. Each municipality has its own offices and deadlines. Visit your town's city hall to find out how much you owe and when it's due.

For your personal income, Hacienda expects you to make estimated tax payments four times a year — not just at the end. If you wait until April 15 to pay everything at once, you could owe interest and penalties. An accountant or CPA can help you figure out those amounts.

Now comes something many people don't expect: you also have obligations to the federal government. Even though Puerto Rico residents generally don't pay federal income tax, they do pay the self-employment tax, which covers Social Security and Medicare. This is done using IRS Form 1040-SS. This is an important difference between Puerto Rico and the 50 states: in the states, people use the regular Form 1040; here, self-employed workers use Form 1040-SS.

Hacienda also receives reports of what your clients pay you through informational forms called 480.6. If you receive payments from companies or platforms, that information has likely already been sent to Hacienda. That's why it's so important to keep your own records of income and expenses throughout the entire year.

This guide does not cover Ley 60 (formerly known as Ley 20/22), which offers a 4% tax rate for certain export services. That law has very specific requirements and does not apply to the typical freelancer or gig worker. Don't let anyone convince you they can cut your taxes using that law without first confirming whether you actually qualify.

Common mistakes to avoid: - Not registering in SURI because you think nobody will notice - Collecting the IVU from clients but not sending it to Hacienda (that can be considered fraud) - Ignoring the patente municipal because it seems minor - Not setting aside money for quarterly estimated tax payments - Falling for schemes that promise to eliminate taxes 'legally' without a solid legal basis

Rules change, so always check with Hacienda, your municipality, or a professional. If you can't afford an accountant right now, Servicios Legales de Puerto Rico (Puerto Rico Legal Services) offers free guidance for people with low to moderate incomes.
