Merchant registration in SURI is the step that lets a business collect IVU and file its monthly return with the Puerto Rico Treasury Department. Without the resulting certificate you should not sell goods or services subject to the tax. 4b2b does not file in SURI: you or your CPA submit the return.
Any business that sells tangible goods subject to IVU, or provides services subject to it, must register as a merchant with the Treasury Department before it starts collecting. Registration is done in SURI and produces the Merchant Registration Certificate, which is displayed at the premises. Someone who sells only online or from home needs it too if what they sell is taxable.
Not every sale carries IVU. Some services, certain food sales and other items are treated differently, and the rules for professional services between merchants have their own logic. So the right question before registering is not “do I sell?” but “which of what I sell is taxable, and at what rate?”, and the answer comes from your CPA using Hacienda’s current instructions.
Register early, because opening a shop, a fair booth or an online store will not wait for the certificate to arrive. Selling before you are registered exposes the merchant to penalties and to paying the tax out of pocket, since the customer never paid it.
Have at hand the entity’s employer identification number (EIN) or the individual’s Social Security number, the certificate of incorporation if it is a corporation or LLC, the physical address, the code for the business activity and an estimate of monthly sales. Hacienda also asks you to name the person responsible for the account in SURI.
A good habit is to create the SURI account under a shared company email rather than an employee’s personal one. When that person leaves, the entity loses access to its own returns, and recovering the account takes weeks. Record somewhere safe who holds the credentials and when the certificate must be renewed, as Hacienda indicates.
Branches and additional points of sale follow their own registration rules. If you open a second shop in another municipality, ask Hacienda whether it needs its own certificate or is added to the existing one, because the answer depends on how your accounts are organized.
The monthly IVU return is filed in SURI by the 20th of the following month, so the real work is organizing the previous month. A simple routine: when the month closes, collect the PDF invoices for the period, separate taxable sales, exempt sales and sales outside the Island, total each group and hand the summary to your CPA to confirm the treatment.
A worked example. A shop issues three invoices in April: $2,000 of taxable merchandise, $800 of taxable merchandise and $1,500 of resale with a certificate. The taxable base is $2,800; at 11.5% the month’s IVU is $322, of which $294 is the 10.5% state component and $28 the 1% municipal one. The $1,500 sits on a separate line, backed by the buyer’s certificate.
The person preparing the return builds that summary, not the system. What 4invoices contributes is an orderly archive in which every invoice is complete, with date, client and amount, so the total does not depend on loose paper.
A merchant who buys goods to resell should not pay IVU on that purchase, because the tax is charged to the final consumer. To get there, the merchant gives the supplier a resale certificate, generated through SURI. The supplier keeps it as proof of why no tax was charged on that sale.
The trouble starts when the certificate is used for something that is not resale, such as office equipment or supplies the company consumes itself. In that case the tax is due, and whoever presented the certificate answers to Hacienda. Before handing a certificate to a supplier, confirm with your CPA which purchases qualify.
On the other side, if you sell to other merchants, require the certificate before you stop charging IVU and file it with that customer’s invoices. An exempt sale with no certificate in the file is the first one Hacienda questions in an audit. Store it with the date you received it.
None of the ecosystem’s products connects to SURI, calculates IVU line by line or prepares the return. 4invoices issues and archives invoices; 4softerp keeps the books. Whatever is filed with Hacienda is filed in SURI by you or your CPA, a distinction worth keeping clear when you evaluate any software.
If the business closes, the merchant registration does not lapse by itself. You need to tell Hacienda that operations have ceased, file any pending returns through the closing date and, depending on the case, request the certificates showing no debts remain. Closing without that step leaves open accounts that keep producing notices. Before cancelling, ask your CPA to review the last period’s returns, because the final one is the one people forget.
Turn the routine into a checklist that anyone on the team can follow. One: confirm that the invoice sequence for the month has no gaps and no duplicates. Two: mark each invoice as taxable, exempt or outside the Island. Three: add the state and municipal IVU shown on the invoices and compare it with the tax payable account in your books. Four: send the summary to the CPA. Five: after the return is filed, save the SURI acknowledgment with the month’s invoices.
A checklist catches the typical month-end surprise. Suppose the invoices total $322 of IVU but the ledger shows $307. Searching by date turns up a $130 invoice for a customer who was later credited; the credit note was issued in the next month and nobody adjusted the first one. Because the sequence and the notes were saved, the gap is explained in minutes instead of days.
Rotate who runs the checklist once a quarter. A routine that only one person understands stops working the day that person is away, and the 20th does not move for vacations.
The 20th arrives and monthly sales have to be reconciled by hand for the IVU return.
Gather the month’s invoices from your invoice archive and work out the totals with your CPA; the monthly return is filed in SURI. The products do not generate an IVU report or connect to SURI.
It is unclear which sales carried IVU and which were exempt.
State on each invoice whether the sale carries IVU or is exempt, as your CPA confirms. The system does not determine the exemption for you.
Suppliers’ resale certificates get lost in inboxes.
Keep a copy of every resale certificate you receive in your ERP or next to the contracts and note its date yourself, so it is at hand if Hacienda asks.
No. The ecosystem does not connect to SURI or prepare the return; you or your CPA file it directly on the Treasury platform. What you can do with 4invoices is keep every invoice of the month as an organized PDF, so whoever prepares the return adds up complete documents instead of scraps.
Selling goods or services subject to IVU without being registered can bring penalties, and you would have to pay from your own funds the tax you never collected from the customer. Amounts and procedure are set by Hacienda, so talk to your CPA before opening to the public and register in good time.
Not necessarily. Some sales are taxable, some are exempt and some services have their own treatment, and what you write on each invoice depends on that. Ask your CPA for a list of your products and services with their treatment and use it as a guide; 4invoices does not decide for you whether a line carries the tax.
The return is filed in SURI and is due by the 20th of the month following the period being reported. If the 20th falls on a non-business day the general extension rule may apply, so confirm the exact date on the calendar Hacienda publishes each year rather than relying on memory, and mark it on the company calendar with an owner.
