IRS Form 15105‑SP is the Spanish‑language version of Form 15105, used to request an automatic extension of time to file a U.S. individual income‑tax return. File it when you need extra time beyond the regular filing deadline.
Plain English
If you owe a U.S. tax return and you can’t finish it by the usual deadline, this form asks the IRS for a six‑month extension. It’s the same request as the English Form 15105, just in Spanish.
