Individuals who cannot complete their federal tax return by the deadline for the following forms can apply with extension Form 4868:
Domestic taxpayers within the U.S. must submit Form 4868 by the extended due date July 15. Also, this happens to be the due date (unchanged) for taxpayers outside of the U.S. and Puerto Rico to submit Form 4868 for a 4-month extension. An extension will give you a six-month extension of time to file but doesn’t give you extra time to pay your taxes.
