IRS extensions for tax year 2018 must be filed on or before these deadlines:
- April 15, 2019 for domestic taxpayers (April 17, 2019 for Maine and Massachusetts residents)
- June 17, 2019 for taxpayers outside the country
It's not possible to file a post-deadline extension.
Keep in mind: An extension doesn't give you extra time to pay your taxes — but it will keep you from getting a late filing penalty. (You'll still owe interest if you pay after the deadline).
- Open your return in TurboTax Online.(To do this, sign in to TurboTax and select the Take me to my return button).
- Select File an extension at the bottom of the column on the left side of the screen.
- If you don't see the File an extension button in Step 2 above, search for extend in the upper right and select the Jump to link at the top of your search results.
- Follow the onscreen instructions to e-file your extension.
Note: If you're paying additional taxes owed with direct debit, you'll need to provide your 2017 AGI for verification purposes (if you didn't file a 2017 return, enter 0 as your AGI).
If you don't have your AGI, or your extension gets rejected for the wrong AGI, here are 2 options:
- Recommended: Pay your taxes at IRS Direct Pay (this also automatically gives you an extension).
- Download and print Form 4868, fill it out, and get it postmarked before 11:59 PM April 15 (June 17 if you were out of the country on the deadline). Payment and mailing instructions are on pages 3 and 4 of your printout.
If you filed prior to the deadline, but were rejected, you have until April 20 (April 22 for Maine and Massachusetts residents) to mail in your extension.
