After you file

You will need to amend if you already E-filed or mailed your return and:

• You need to report a tax form you forgot about or received post-filing (most commonly a W-2, 1099, or 1095-A).
• You received a corrected tax form after filing (the "corrected" box is checked) and the new info changes your refund or tax due amount.
• You forgot to report income or claim dependents, deductions, or credits.
• You accidentally claimed dependents, deductions, or credits you're not eligible for.
• You made an error that affects your bottom line, such as reporting income or deductions in 2020 that should've been claimed in a prior tax year (in that case, you'll need to amend all affected tax years).
• You need to change your filing status (for example, you want to change from Single to Head of Household).

If you need to amend your 2020 return you must wait until the IRS either accepts or rejects your return.

If the IRS rejects your return, you can make the changes and re-submit your return.

If the IRS accepts your return, you have to wait until it has been fully processed and you have received your refund. Then you can prepare an amended tax return and mail it in.
