In short
The Registro de Comerciante is your business’s registration with the Puerto Rico Treasury Department, requested through SURI, Hacienda’s online system. It is needed before you start operating, and you need one registration per location or point of sale. The certificate is displayed at the business, and it comes with recurring sales-tax filing and remittance obligations.
What is it?
The Registro de Comerciante is your business’s entry in the registry maintained by the Treasury Department (Hacienda). When you register you receive a Merchant Registration Certificate, the document identifying you as an authorized merchant, which is displayed in a visible spot at the business. It is the filing that enables you to collect and remit the IVU (Puerto Rico’s sales and use tax) when your activity requires it, and it is what suppliers, banks and municipalities will ask for as proof that the business formally exists. It applies to large and small businesses alike: the size of the business is not what determines whether you must register — the activity you carry out is.
Who can do it?
It applies to any person or entity doing business in Puerto Rico, including people operating on their own under their own name — not just entities registered with the Department of State. If you sell goods or provide services on the island, you most likely need the registration, and you register before you start operating, not after the first sale. Each location, branch or point of sale needs its own registration, even when they all belong to the same owner. If you are not sure whether your activity requires registration, confirm it with Hacienda or a CPA before assuming it does not.
Requirements
- A SURI account in the name of the person or entity that will operate the business: Hacienda states that the Registro de Comerciantes is done electronically through SURI, and that the certificate is issued under Section 4060.01 of the 2011 Puerto Rico Internal Revenue Code.Verified against the official source
- The entity’s employer identification number (EIN), or your Social Security number if you operate as an individual. Hacienda states that the EIN is requested from the IRS (irs.gov, 1-800-829-4933, or Form SS-4PR) and that, once you have it, you must give the Department Form SC 4809, “Informe de Número de Identificación Patronal – Organizaciones (Patronos)”, so the employer record is created.Verified against the official source
- The physical address of each location or point of sale you will register, and the business’s mailing address.
- A description of the business activity and the date you begin operating.
- If the business operates as an entity, its Department of State registration information.
- Information about the owners, partners or officers that Hacienda requires for your business type.

Step by step
Step 1: Understand what SURI is before you start
SURI (Sistema Unificado de Rentas Internas) is the online portal where Hacienda concentrates nearly everything tax-related: you register as a merchant there, file IVU returns, make payments, request certifications and receive the agency’s notices. It is a single login containing several "accounts," one per type of obligation you carry. It is worth setting the account up carefully from the start, because everything that follows — notices, balances, certifications — will arrive through it.
Step 2: Gather the entity and location information
Before opening the application, have at hand the EIN (or your Social Security number if you operate as an individual), your Department of State registration details if you are an LLC or corporation, the exact physical address of each location, and a description of your business activity. Stopping halfway to hunt for a number is the most common reason people leave the application unfinished.
Step 3: Create your SURI account
Register the account in the name of whoever will operate the business: if the business is an LLC, the account belongs to the LLC, not to you personally. Use an email address you will genuinely keep access to, and store the credentials safely; recovering access to an abandoned SURI account is far slower than setting it up right the first time.
Step 4: Request the Registro de Comerciante inside SURI
Inside your account, find the Registro de Comerciante application and complete it for each location you will operate. Pay attention to the start-of-operations date and to how your activity is classified, because that determines which obligations get assigned to you. If you have more than one point of sale, each is registered separately under the same account.
Step 5: Get and display the certificate
Once Hacienda approves the application, the certificate becomes available in your SURI account. Print it and display it in a visible spot at the business, and keep a digital copy handy: you will be asked for it for municipal permits, to open a bank account, and to set up accounts with suppliers.
Step 6: Register by phone with the IVU Fiscal Supervision Program
This step surprises a lot of people because it does not happen inside SURI. Hacienda states that once you receive your Merchant Registration Certificate, you are obligated to register for the IVU Fiscal Supervision Program by calling (787) 200-7900, Option 4. On that call you answer a questionnaire that determines whether installing and using an IVU fiscal terminal applies to you. Hacienda clarifies that this does not apply to merchants registered as temporary businesses or as exhibitors.
Step 7: Keep up with what comes after
Registering is not the end: as a registered merchant you must file and remit the IVU on the schedule Hacienda assigns you, even in periods when you sold nothing. Zero returns still get filed. Also, if you move, close a location or change your activity, you must update it in SURI. Confirm your filing calendar inside your own account, because it is not the same for every merchant.
Where to do it
Online, through SURI, the Treasury Department’s system. The Registro de Comerciante page greets you with four options under “¿Qué desea hacer?”, and it pays to pick the right one from the start: register for the first time (for anyone never registered before), update the registration (which Hacienda limits to merchants providing designated professional services), add additional locations or activities, and register to declare imports (for individuals who are not merchants and who incidentally import something for personal use rather than resale).
How long it takes
What to do if something goes wrong
The most common snags are about access, not content: accounts created under the wrong name, email addresses nobody checks anymore, or the one person with access having left the company. If you cannot get into SURI, use the system’s own recovery flow before creating a new account — duplicate accounts complicate your record. If the certificate does not appear after approval, check that you are looking at the right location within the account, since each point of sale has its own. For balances, notices you do not understand, or questions about which obligations apply to you, contact Hacienda directly or consult a CPA licensed in Puerto Rico. PRFácil does not file applications and does not provide tax advice.
Common mistakes
- Starting to sell first and registering later, when registration happens before you begin operating.
- Using a single registration for several locations, when each point of sale needs its own.
- Creating the SURI account under a personal name when the business operates as an LLC or corporation.
- Skipping filings in periods with no sales, assuming that no income means no return is due.
- Not updating an address change or a location closing in SURI, and continuing to accrue obligations for a business that no longer operates.
- Treating the process as finished once the certificate arrives, without calling (787) 200-7900 Option 4 to register with the IVU Fiscal Supervision Program — a separate obligation that is not handled through SURI.
Frequently asked questions
What exactly is SURI?
SURI is the Unified Internal Revenue System, the Treasury Department’s online portal. It is where you register as a merchant, file returns, pay, request certifications and receive the agency’s notices. Think of it as your tax file online: a single account that groups all your obligations with Hacienda.
Do I need the Registro de Comerciante if I only sell services?
Doing business in Puerto Rico generally requires registration whether you sell goods or provide services, and IVU treatment is not the same for every activity. Confirm how yours is classified with Hacienda or a CPA before assuming you are exempt.
Do I have to register the LLC before requesting the Registro de Comerciante?
If the business will operate as an LLC or corporation, yes: you first register the entity with the Department of State and obtain the EIN, because the Registro de Comerciante is requested in that entity’s name. If you operate as an individual, no entity registration is needed.
How much does the Registro de Comerciante cost and how long does it take?
Fees and processing times are set by Hacienda and can change. PRFácil does not publish figures it has not verified with the agency; check what is current on the official site or inside your SURI account.
I am going to resell merchandise. Do I need anything beyond the registration?
Hacienda describes the Reseller Certificate as the document the Secretary issues to a merchant already entered in the Merchant Registry, certifying that the merchant sells articles or merchandise. So the registration comes first and the certificate after, not the other way around. The request is made electronically through SURI. If your business is a manufacturing plant, there is also an Exemption Certificate for Manufacturing Plants, likewise through SURI.
What happens if I close the business?
Closing is also reported in SURI. A registration left open keeps generating filing obligations, and those do not go away on their own just because you stopped operating. Confirm with Hacienda the cancellation procedure that applies to your case.
