Starting in tax year 2022, e-filed 1040-X returns can receive a refund by direct deposit. Paper filed amendments will still be issued refund checks by mail.

Before you start:

• We recommend creating a copy of the original return to save your entries as filed. 
• If you didn't prepare the client's original 1040, or you prepared it in a different program, use Amending an individual return (1040X) not created in ProConnect Tax, instead.
• 1040NR filers only complete a few portions of Form 1040X when amending. See Form 1040X instructions for more details.
