Definition of 'Form 1040X'

The Form 1040X is an IRS form used to amend a previously filed federal income tax return. It can be used to correct errors, claim a refund, or make changes to your return. The form must be filed within three years of the original due date of the return, or two years from the date the tax was paid, whichever is later.

The Form 1040X is a complex form, and it is important to complete it correctly. If you are not sure how to fill out the form, you should seek professional help.

Here are the steps on how to file an amended return:

1. Gather all of the information you will need to complete the form, including your original tax return, any supporting documents, and the reason for the amendment.
2. Download the Form 1040X from the IRS website.
3. Carefully fill out the form, being sure to include all of the required information.
4. Sign and date the form.
5. Attach any supporting documents to the form.
6. Mail the form to the IRS address listed on the form.

The IRS will review your amended return and issue a refund or adjust your tax liability. You will receive a letter from the IRS informing you of the results of your amended return.

It is important to note that you may have to pay penalties and interest if you file an amended return after the due date. The IRS may also assess additional taxes if you owe money.

If you are unsure whether you need to file an amended return, you should consult with a tax professional.
