FAQ

Frequently asked questions

Straight answers to the questions we hear most. Don't see yours? Ask us.

Form 1040 is due April 15 each year (or the next business day). You can extend the filing deadline to October 15 with Form 4868, but any tax owed is still due April 15 to avoid interest and penalties.
