Form 480.7A Guide: What Private Lenders in Puerto Rico Need to Know

What is Form 480.7A?

Form 480.7A (Declaracion Informativa — Intereses Hipotecarios) is a Puerto Rico informative return that the lender must issue to the borrower. It documents the mortgage interest the borrower paid during the tax year — which the borrower needs to claim as a deduction on their income tax return.

Think of it as the Puerto Rico equivalent of the federal Form 1098. As the lender, your obligation is to issue the form accurately and on time. You don't use the 480.7A for your own taxes — you simply report the interest you received as regular income on your return. But your borrower depends on this form to take their deduction.

Who needs to issue it?

Hacienda's instructions require Form 480.7A from a person or entity that receives mortgage interest in the course of a trade or business. In practice this covers active private lenders and many owner-financing sellers, but whether a single seller-financed note rises to a "trade or business" is fact-specific — if you hold just one note, confirm with a Puerto Rico CPA whether you are required to issue the form. Unlike the federal 1098, there is no minimum-dollar threshold: when the form applies, it applies regardless of the interest amount.

If you're a mainland US lender with a Puerto Rico property, the same trade-or-business analysis applies and can be more complex. Consult with your CPA for cross-jurisdiction situations.

When is it due?

When the form applies, it must be filed with Hacienda annually by January 31st for the previous tax year. For example, interest received during 2026 must be reported on a 480.7A filed by January 31, 2027.

You must also give the borrower their copy by the deadline stated on the current-year form so they can use it for their own filing — check the year's official instructions for the exact borrower-copy date. Late filing can result in penalties from Hacienda, and your borrower can't claim their interest deduction without it.

What information is required?

The form requires: your name and Social Security Number (or EIN), the borrower's name and SSN, the property address, the total interest paid by the borrower during the tax year, the outstanding principal balance as of December 31, and the original loan amount.

The critical number is the interest calculation. Each monthly payment on an amortizing loan is split between principal and interest. The interest portion changes every month as the principal balance decreases. Getting this wrong means your borrower claims the wrong deduction and your reported income doesn't match — both returns get flagged.

The interest calculation challenge

For a standard amortizing mortgage, the interest portion of each payment is calculated as: (outstanding balance x annual interest rate) / 12. As the borrower pays down the principal, the interest portion decreases and the principal portion increases.

If you're tracking this in a spreadsheet, one late payment, one extra payment, or one missed month throws off every subsequent calculation. By December, the cumulative error can be significant — and you won't know until your CPA tries to reconcile the numbers.

How to generate Form 480.7A automatically

Tools like Lend. calculate the interest split for every confirmed payment throughout the year. When January comes, you enter the SSN at the moment of generation (it's never stored), and the form is produced as a downloadable PDF with all the correct numbers.

The form includes all required fields: lender and borrower information, total interest paid, outstanding balance, and property details. You get the lender copy and the borrower copy — ready to file with Hacienda and hand to your borrower so they can claim their deduction.

Form 480.7A vs. Form 1098

If you receive the interest in the course of a lending trade or business, you may also need to issue Form 1098 (the IRS equivalent); a one-off seller-financer on a former residence generally is not required to file it, and the borrower instead deducts using your name and SSN. When it does apply, the 1098, like the 480.7A, is issued by the lender to the borrower and reports the same interest paid so the borrower can deduct it on their federal return. As the lender, you report the interest received as income on your own return either way.

The underlying data is the same — total interest paid and outstanding balance. If your 480.7A numbers are accurate, your 1098 numbers will be too. Tools that generate both from the same payment data eliminate the risk of discrepancies between your Puerto Rico and federal filings.
