Form 1040-X, 1040X Tax Amendment

Income tax returns are due by the April IRS tax deadline, however, they can still be e-filed by the October deadline here on eFile.com.

New for 2023 Returns!: You can also prepare and efile your current tax year tax amendment from your eFile.com account if you filed your latest IRS return on eFile.com and it was accepted by the IRS. If you did not use eFile.com, you can still use the tax app to prepare your tax amendment by fully preparing the correct return from scratch. We do recommend preparing your return on eFile.com that way if an amendment is needed, you only need to make the corrections instead of re-entering all of your data.

If you e-filed your IRS accepted return on eFile.com, you can complete AND efile your federal amendment on eFile.com. See instructions for state tax amendments which can be prepared on eFile in most cases before being mailed in. Resources and instructions for tax amendments can be found below.

1) Tax Amendment for eFile.com ONLY Taxpayers

This assumes that you have prepared and e-filed an IRS accepted tax return on eFile.com for the current tax year. Here are instructions to prepare and efile your federal tax amendment only if you e-filed it via eFile.com. For all other tax years, visit this tax amendment page or read Section 2 below.

Step-by-step amendment instructions for eFile.com users.

2) Tax Amendment Instructions for NON eFile.com Taxpayers

If you efiled your current IRS tax return on a different site other than eFile.com (H&R Block^® or TurboTax^®, etc.) and it was accepted by the IRS, you can NOT efile your tax amendment via eFile.com. In that case, either use the app where you prepared and eFiled your tax return, or prepare your tax amendment Form 1040-X 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.

Your IRS Tax Amendment Status

Once you have mailed in your federal tax amendment Form 1040X, it can take up to 16 weeks (or 4 months) from the IRS receipt date until the form is processed. You can check the status of your amended return on the IRS Amended Return Status tool by clicking the link below and clicking on What Is Your Federal Tax Return Amendment Status? You can also call the IRS amended return hotline at 1-866-464-2050.

Check Your IRS Tax Amendment Status

Note: The IRS "Where's My Refund" online tool does not keep track of amendment refunds.

If you are amending a return in order to get an additional tax refund, you can go ahead and cash or deposit any refund you get in the meantime. However, do not file your amended return until after you receive the refund. It generally takes the IRS 16 weeks (or 4 months) to process an amended return, so you should wait at least 10 weeks before checking on the status of your new amended tax refund. Once your amended return has been processed, you will receive any additional refund you are owed.

Refund From Amendment

If it has been over 16 weeks (or 4 months) and you still have not received your amended refund check, you can find more information about your refund by calling the IRS amended return hotline at 1-866-464-2050.

We at eFile.com generally recommend waiting until after January 31 to e-file your returns. Why? This is the date that your various statement tax forms, such as your W-2 reporting income, are required to be sent. Be sure you have received all of your forms so you do not have to file an amendment - start tax planning now. Use this tax refund calculator to estimate your taxes and get ready for next year.
