Form 1040-X is an official document provided by the Internal Revenue Service (IRS) used by taxpayers to amend a previously filed annual federal tax return. This form becomes necessary when errors or omissions are discovered after the original tax return has been filed.
Purpose of Form 1040-X
Correcting Mistakes
Form 1040-X is primarily used to correct mistakes on a previously filed Form 1040, 1040-A, 1040-EZ, 1040-NR, or 1040-NR-EZ. This can include:
- Incorrectly reported income
- Misreported filing status
- Errors in calculating deductions or credits
- Omissions of dependents
Claiming Additional Refund
Taxpayers may also file Form 1040-X to claim a previously overlooked tax credit or refund, potentially increasing their refund amount.
