When filing Form 1040-X to amend your tax return, it’s important to be aware of the following key facts to ensure that your tax filing is accurate and complete:
- Personal Information on Form 1040: When filing your return (including any amended returns using Form 1040-X), make sure to include your personal information, such as your name, address, Social Security number, and filing status. These details are essential for the IRS to correctly process your tax return.

- Schedule 1 for additional income or adjustments.
- Schedule 2 for additional taxes.
- Schedule 3 for nonrefundable credits.

- Form 1040-SR: If you’re 65 or older, you may be eligible to file Form 1040-SR, which includes a built-in standard deduction table and larger print for easier readability.
