The combined IVU in Puerto Rico is 11.5%: 10.5% for the State and 1% for the municipality. For the return to reconcile, each invoice should show the base, both tax components and any exempt items separately. 4invoices produces the PDF, but how each line is treated is decided by your CPA.
The Sales and Use Tax, known as IVU, has two components that are charged together to the consumer: 10.5% that belongs to the State and 1% that belongs to the municipality. The customer pays one total, but the monthly return separates the two components, which is why the invoice should reflect them separately.
On a $1,000 base, IVU comes to $115: $105 for the State and $10 for the municipality, and the customer pays $1,115. On a $250 base the tax is $28.75: $26.25 State and $2.50 municipal. Inconsistent rounding line by line can accumulate differences of cents which, over hundreds of invoices a month, keep the return from matching the books.
Decide with your CPA whether rounding happens per line or on the invoice total and apply the same rule every time. Write it in an internal note so that whoever issues invoices two years from now does it the same way.
Keep a one-page rate sheet next to the invoice template. It lists the state and municipal percentages, the rounding rule, the wording for exempt lines and the name of the person who approves changes. When Hacienda or the municipality changes a rate, the sheet and the template are updated on the same day, and every invoice after that date follows the new version.
Not everything a merchant sells is subject to the tax. There are exempt sales, certain food sales with special treatment and services that receive different treatment, among them some professional services between merchants. Sales to buyers who purchase for resale are documented with a resale certificate, and exports or sales outside the Island are analyzed separately.
The best working tool is a table your CPA prepares with every product or service you sell, its treatment and the legal reference. With that table, whoever issues the invoice does not improvise. If the business adds a service, update the table before billing the first customer.
Remember that the IVU you collect is not the merchant’s income; it is money collected on behalf of the State and the municipality. Mixing it with working capital is the cause of many late payments: the 20th arrives and the cash has already been spent.
A useful invoice for IVU purposes identifies the merchant by legal name and registration number, the date, the customer, a description of each item, the price, the tax shown separately and the total. If there are discounts, state the amount on which the tax is computed, and label exempt items as such, on their own line or section.
With 4invoices you customize the PDF template with those fields and archive each document by customer and date. The figures that go in the fields are written or validated by you; the program does not look up Hacienda rates or decide whether a line carries the tax.
Keep sequential numbering without gaps. If an invoice is voided, keep the original PDF, mark it as voided and issue the correction as a new document. Unexplained gaps are the first thing an auditor asks about.
If you invoice in more than one currency of account or language, standardize the labels too: “Subtotal”, “State IVU”, “Municipal IVU” and “Total” should read the same on every document, so your CPA can scan a month of PDFs without translating.
When a customer returns goods or a discount is agreed afterward, the IVU collected must be adjusted in the same direction. The clean way is a credit note that cites the original invoice, with the amount and the tax returned itemized as in the original. That document is reflected in the return for the month in which it is issued.
An example: in March you sell equipment for $2,000 plus $230 of IVU; in April the customer returns half. The April credit note is $1,000 plus $115 of IVU. Your CPA adjusts the April return with that credit, not March’s. If the note does not cite the source invoice, nobody can reconstruct the link later.
Avoid fixing mistakes by deleting and rewriting an invoice already sent. Every issued document is part of the record; changes are made with new documents that explain what they correct.
When you sell to a customer in another US state or abroad, the treatment of IVU and of the destination’s tax changes and needs analysis. Do not assume the tax is or is not charged: let your CPA determine what applies and note it on the invoice with the same clarity.
On the purchasing side, when you buy goods outside Puerto Rico for use here, use tax may be due and is reported on the return. It is a different concept from the IVU on your sales and is often forgotten. Ask your CPA to review your online purchases from the last year to see whether anything is outstanding.
Before your CPA prepares the return, run a simple check: sort the month’s invoices by number, confirm none is missing or duplicated, total separately the taxable base, the exempt base and the state and municipal tax, and compare the result with the tax payable account in your books. If the two figures differ, the gap almost always sits in a voided invoice, a credit note or a rounding rule.
A typical finding: the invoice list totals $4,830 of taxable base but the ledger shows $4,630. The search turns up a $200 invoice issued on the 30th and entered on the 2nd of the next month. Recording by the document date, not the date it is keyed in, keeps every month from inheriting the same lag.
Save that check, dated, with the month’s invoice PDFs. If Hacienda asks about a period, you will have the whole chain: invoices, summary, return and payment.
The invoice shows a single IVU and the municipal share cannot be separated later.
Write the state (10.5%) and municipal (1%) IVU on your PDF invoices as Hacienda indicates. 4invoices does not calculate IVU per line or split it for you.
Exempt and taxable items on the same invoice cause errors.
Identify exempt and taxable items on each invoice yourself, with your CPA. The system does not apply IVU treatment automatically.
A credit note is never tied to its original invoice and the month’s IVU ends up unbalanced.
Issue the credit note as its own document that quotes the original invoice number, and store both PDFs together for your CPA.
No. 4invoices issues PDF invoices and archives them, but it does not apply IVU rates or decide the treatment of each line. You write the state and municipal tax amounts as your CPA indicates, and the program displays them in the document. The return is prepared and filed outside the system, and IVU payments go directly to Hacienda. Treat the program as the place where documents are written and stored, not where the tax is determined.
It is the recommended practice, because the monthly return separates both components and the invoice is the basis for that information. Ask your CPA what Hacienda requires for your type of sales and use the same presentation on every document you issue, without changing the layout from one customer to another, since consistency makes the monthly review much faster.
Do not delete or rewrite it. Keep the original PDF, issue a credit note quoting its number and, if appropriate, a new invoice with the correct treatment. Tell your CPA so the adjustment lands in the right month’s return, and file the three documents together under the customer’s name so the trail is easy to follow.
No. The tax charged to customers is received on behalf of the State and the municipality and is remitted with the return; it is not part of the business’s income. In the books it is recorded as a liability until paid. Mixing it with operating cash is a frequent cause of late payments, so many owners move it to a separate account the day it is collected.
You set the IVU; ask your CPA how each item is treated.
