Can I still file my taxes in TurboTax after the October 15 deadline?

If you missed the October 15 tax extension deadline, but already started your return in TurboTax Online, you generally have until October 31 to file your return online in TurboTax, but it may be subject to late filing fees.

After October 31, you can't start, finish, or e-file new returns in TurboTax Online. You'll need to use TurboTax Desktop, and mail your return.

What if my return was rejected and I want to fix it after October 31?

If your return is rejected after the deadline, you have until October 20 to fix and resubmit your return to the IRS without late-filing fees. After mid-November, you'll have to use TurboTax Desktop to mail your return for your rejected return. This help article has more details.
