How to File an IRS and/or State Tax Amendment

These step-by-step instructions guide you through preparing your IRS tax amendment on eFile.com for the 2023 tax year. Find instructions on how to complete various state tax amendments.

• Attention: If you did not use eFile.com to prepare and e-file your original 2023 year tax return, you can NOT e-file your tax amendment via eFile.com. In that case, either use the app where you filed your tax return, or prepare the 1040-X amendment paper form for free and mail it in. If you e-filed an IRS tax amendment via eFile.com, you do not need to mail it in.

3. IRS Tax Amendment Status

Once you have e-filed your tax amendment, follow these steps to check your IRS tax amendment status.

4. IRS Tax Payment as a result of the Tax Amendment

If you owe taxes as the result of the amendment, we recommend you first e-file it and do not pay during the e-filing process. Once the Tax Amendment has been accepted, pay directly at the IRS site. You do NOT need to mail in the form 1040-X if you e-filed the form. If you created the 1040-X tax amendment on paper, include a check with the tax amendment and mail it to the IRS mailing address for your tax amendment.
Tip: In case you owe taxes, file the tax amendment even if you can not pay taxes due at this time, as you would not face potential late filing penalties which are generally higher than late payment penalties. Other tax payment options are listed here.
