I put the wrong middle initial. Will I have to amend my returns?

[EricG1]

You shouldn't need to. Usually the only reasons to amend are:

• 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 2016 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 (e.g., you want to change from Single to Head of Household).
• We instructed you to amend because of a program error (uncommon).

Unless you receive communication from the IRS, you shouldn't need to amend your return because of an incorrect middle initial.
