What is an amended tax return 1040x

To amend a 1040 return:

1. Do a print preview of the return.
2. Review the Form 1040 to see if it has the same information originally reported to the IRS. For now, just make a note of whether it's the same.
3. Go to the Amend screen, in the Separate Filings folder.
4. If the Form 1040 matches what was originally reported to the IRS, mark the Transfer original information field. All the amounts from the return will automatically transfer to the screen.
5. If the Form 1040 does NOT match what was originally reported, enter the original amounts in the fields on the screen. Do NOT mark the Transfer original information field.
6. If you are also amending a state return:
   • Select the applicable state in the Transfer state(s)? window.
   • Mark the Transfer original information checkbox on each state's Amend screen.
   • To amend the state return only, leave this screen blank and mark the Transfer original information checkbox in the state’s Amend screen.
7. Enter information in the Explanation of changes field. The Form 1040X will not fill out unless this field has something entered in it.
8. Make your changes to the return on the other data entry screens. For example, to change the wages, go to the W2 screen and enter the correct wage amount.
9. Print or e-file the return. There are special data entry requirements for e-filing Form 1040X.

Notes:

• You cannot amend prior-year returns in the current-year application. Amended returns can only be completed using the same version of the application that was originally used.
• For domestic partner returns:
  • To amend the federal return, follow the amend process in the single federal return.
  • To amend the state return, complete the amend process in the combined state return.

While many people think taxes are a “set it and forget it” task — this is not actually the case. In fact, if you find errors or you left out information on your original return, you can use Form 1040X: Amended Tax Return to file a corrected version of your federal return.

What are the benefits of filing an IRS amended return?

• Claiming a tax credit
• Taking a deduction you missed
• Reporting additional income and withholding

In fact, by filing the 1040X form for an amended return, you might:

• Receive an additional refund; or
• Owe additional taxes as a result of the correction.

If you’re due a refund, the IRS will send it to you after it accepts your amended return. If you owe tax, send the amount owed to the IRS along with the 1040X tax form. If you owe interest or a penalty, the IRS will bill you.

What to look for when you file the 1040X form

When you amend a return for a specific reason, it’s a good idea to review your entire original return. Look for the following things you might have missed the first time around, like:

• Deductions
• Credits
• Exemptions
• Income
• Withholding

When you do this, you might wind up owing less money or getting more of a refund.

Who can file an amended tax return using Form 1040X?

You can amend your taxes as long as your original tax return was prepared using a 1040 form or 1040SR.

What to include in your amended return

When you file a 1040X tax form, you might wonder what to include in your amended return. You’ll need to attach these items if you need to prove the changes on your amended return:

• A copy of the federal refund deposit slip
• Any previously unsubmitted W-2 or 1099 forms
• Any other substantiating forms, schedules, or documentation supporting the amended return

To file an amended tax return, you can either e-file or download a paper Form 1040X from www.irs.gov. You must mail the paper form if you choose to paper file. You can also do so with the help of H&R Block, with our various filing options and products.

If I’ve already filed my return for this year, can I amend my tax return to add dependents to my 1040-X? Can I also add a dependent on a prior year?

Yes, you can file an amended return this year. You can add dependents to any of the past three years returns or within two years after the date you paid the tax, whichever is later. If you have an amount due that can be reduced you can file later than this date. To add or change the number of your qualifying dependents, you should print and mail an amended tax return for each affected year to the IRS. You can’t e-file Form 1040X. If you’re filing a 2020 return, it can be filed electronically unless you or your spouse changed your Social Security number or your filing status changed.

Due date for filing Form 1040X

To obtain a refund, you usually must file an amended return by the later of these dates:

• Within three years from the date you filed your original return
• Within two years from the date you paid the tax

If you received an extension, the filing date is one of these:

• Actual date you filed your return within the extension period
• Tax deadline if you filed your return after the extension period expired

If you’re filing an amended tax return due to a bad debt or a worthless security, you have more time to file. In this case, you have seven years after your original return’s due date to file the amended return.

If you’re a business owner, you can also file an amended tax return for a year when you carried a net operating loss (NOL). You must file the amended return within three years of the due date of the return for the NOL year.

The IRS usually has three years to assess additional taxes. However, longer periods are allowed for significant underreporting of income and fraud.
