In short
Any taxpayer may request an extension to file their return, and for individuals it is automatic: request it on or before the deadline and you get six additional months. It is requested using Form SC 2644. What you need to understand first is that the extension extends the time to file, not to pay: if you owe tax, you must pay it together with the extension request, or interest, surcharges and penalties start accruing.
What is it?
An extension is a request for additional time to meet the obligation to file your income tax return. Hacienda explains that when it is requested and approved, the taxpayer gets additional time to file. For individuals, estates and trusts the extension is automatic: there is no wait for someone to evaluate it and no need to justify why you need it; filing the request on time is enough. What the extension does not do — and Hacienda says so twice on its own page — is move the payment date.
Who can do it?
Hacienda states the extension may be requested by any taxpayer who needs additional time to file their return. There is no list of acceptable reasons and no special circumstance to demonstrate. What does determine your case is the deadline that applies to you, because it is not the same for everyone: it depends on the type of taxpayer and on whether you determine your income on a calendar-year or fiscal-year basis.

Step by step
Step 1: Work out what you owe before requesting the extension
This is the step people skip and the one that costs money. The extension gives you time to file, not to pay. Hacienda is explicit: if you have tax to pay with the return, that tax must be paid together with the automatic extension request, precisely to avoid accruing interest, surcharges and late-payment penalties. Even without the return finished, you need a reasonable estimate of what you owe.
Step 2: Confirm your deadline, which is not always April 15
Hacienda publishes different dates by taxpayer type, and only one of them is April 15. Individuals, estates, trusts, corporations, nonprofits and several other figures fall on April 15. But partnerships, special partnerships, corporations of individuals and grantor trusts fall on March 15 — a month earlier. Foreign corporations without an office in Puerto Rico, persons subject to Act 154-2010, and non-resident foreign individuals fall on June 15. Employee trusts, on July 31.
Step 3: Adjust the date if you file on a fiscal-year basis
All the dates above are for those who determine income on a calendar-year basis. If you file on a fiscal-year basis, the date is calculated from your year-end: the fifteenth day of the fourth month following the close for those who would go to April 15, of the third month for the March 15 group, of the sixth month for the June 15 group, and the last day of the seventh month following for employee trusts.
Step 4: Complete Form SC 2644
That is the form Hacienda names for requesting the extension, and it publishes it for download on its own page. If you are a partnership that elected to be taxed as a corporation, Hacienda asks you to select the block for Corporation or for Corporation under the Puerto Rico Tax Incentives Program, as applicable: that detail is easy to overlook and it determines how your request is classified.
Step 5: File on time and keep the proof
The extension is automatic only if the request arrives on or before the deadline. A late request does not give you the six months. Keep the proof of filing and of the payment you included: if Hacienda later notifies you of a late-filing charge, that evidence is what lets you respond.
Where to do it
Hacienda publishes Form SC 2644 for download on its request-an-extension page, within the individual Income Tax section. Since Hacienda concentrates tax filings in SURI, confirm in your own account whether the request should be filed there or on paper for your taxpayer type.
How long it takes
For individuals, estates and trusts there is no waiting: Hacienda calls it an “automatic extension”. If you file the request on or before the deadline, you automatically get a six (6) month extension to file the return. Hacienda gives the example directly: someone who submits the request on or before April 15 automatically has until October 15 to file.

What to do if something goes wrong
If a late-payment notice arrived after you requested an extension, it is most likely not an error: the extension covers filing, not payment, so interest and surcharges on what you owe run from the original date. If a late-filing charge arrived despite the extension, check the date your request came in: if it arrived after your deadline, the automatic extension did not apply. And if the date you assumed was not yours — the classic case is a partnership going by April 15 when March 15 applied — the request was late even if you sent it weeks ahead. For questions about your own case, about how much to estimate, or about a notice you do not understand, consult a CPA or a return specialist registered with Hacienda. PRFácil does not file requests and does not provide tax advice.
Common mistakes
- Believing the extension gives you until October to pay. It extends filing, not payment, and interest, surcharges and penalties run from the original date.
- Requesting the extension without paying anything when tax is in fact owed, instead of accompanying the request with the estimated payment.
- Being a partnership, special partnership, corporation of individuals or grantor trust and going by April 15, when the date is March 15.
- Filing on a fiscal-year basis and using the calendar-year dates.
- Filing the request after the deadline and expecting the automatic extension to apply anyway.
- Not keeping proof that the extension was filed, and having nothing to answer a later notice with.
Frequently asked questions
Does the extension give me more time to pay?
No, and this is the costliest confusion in the whole process. Hacienda says it twice on its own page: the extension does not extend the payment of the tax or any of its deadlines. If you owe, you must pay along with the extension request to avoid interest, surcharges and late-payment penalties.
Do I have to explain why I need the extension?
No. Hacienda states any taxpayer who needs additional time may request it, and for individuals, estates and trusts it is automatic: if the request arrives on time, the six-month extension is granted without any review of reasons.
How much time do I get?
Six months, for individuals, estates and trusts. Hacienda gives the example: someone who submits the request on or before April 15 automatically has until October 15 to file the return.
How much does requesting the extension cost?
Hacienda does not publish a charge for filing Form SC 2644, but neither does it expressly say it is free, so PRFácil asserts neither. What is clear is the other side of the ledger: if you owe tax and do not pay it with the request, what accrues is interest, surcharges and penalties.
