Option 2: Print and mail your completed IRS extension form
If you’d rather mail your extension directly to the IRS, simply refer to IRS Form 4868: Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, complete and print the form, and send it to the IRS address for your state.
If you owe federal taxes, include your estimated payment with your Form 4868 and mail it—postmarked by April 17, 2018 to avoid any penalties or interest. Then complete and file your return on or before October 15, 2018.
