After you file

This is an advise tax forum so we can't review your filed income tax return. Please post why you think you need to amend, and we'll let you know if you do need to amend.

You may try and contact us to discuss amending with an agent. Click here.

•  We also have a paid service. See What is TurboTax Live? Generally, you're able to purchase this service prior to filing a tax return. 

Usually, you need to amend if the additional information affects your bottom line (your refund or amount due). Below are the reasons you will need to amend if you already mailed your return (or the government accepted your e-file) 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).
• We instructed you to amend because of a program error (uncommon).

Generally, Form 1040-X,  Amended U.S. Individual Income Tax Return, must be filed within three years of the date the original return was filed, or within two years of the date the tax was paid, whichever is later.
