Video Tips: Forget Something on Your Tax Return?

If an error is discovered after filing a return, it can be amended (corrected). Before the return’s due date has expired, a whole new return, called a superseding return, can be submitted. After the due date has gone by, use Form 1040-X to correct a previously filed Form 1040, 1040-SR, or 1040-NR, or to change amounts previously adjusted by the IRS. You can also use Form 1040-X to make a claim for a carryback due to certain losses or unused credit or make certain elections after the deadline.
