I applied for a federal request extension online. Does the extension apply to my state return, too, or do I have to request a state filing extension and file state tax extension as well?

Most states don’t require you to file separate state extension forms if you don’t owe any additional taxes. When you file your state return, you only need to attach a copy of your federal extension form.

If you owe state tax, you typically must file state tax extension to avoid penalties. Contact your state tax office to verify the state extension requirements and to get the extension form.
