Current IRS Processing Times for Amended Returns

The IRS is processing amended returns, but the timeline depends on how you file and what the IRS finds when it reviews your return. If you file an amended return on paper, expect 8 to 12 weeks for the IRS to process it. If you file electronically through tax software or a tax professional, processing typically takes 4 to 6 weeks, though this can vary based on IRS workload and whether your return requires manual review.

The IRS processes amended returns in the order they arrive, not by priority. A return filed in January will move through the queue faster than one filed in July, simply because fewer returns are ahead of it. If your amended return contains errors or requires verification, the IRS will send you a notice by mail — this adds time beyond the standard processing window.

You can check the status of your amended return using the IRS Where's My Amended Return tool on IRS.gov, but only after the IRS has received and begun processing it. This tool typically becomes available about three weeks after you file.

Key Takeaways

  • Paper amended returns take 8 to 12 weeks to process; electronic returns typically take 4 to 6 weeks.
  • The IRS processes amended returns in the order received, so filing earlier in the tax year usually means faster processing.
  • You can track your amended return status using the IRS Where's My Amended Return tool after three weeks have passed.
  • If the IRS finds issues with your amended return, they will mail you a notice, which adds additional time to the process.

Why Amended Returns Take Longer Than Original Returns

Amended returns require manual review at some point in the process, even if they are filed electronically. The IRS system flags amended returns for human review because the agency needs to understand why you changed your original return and verify that the changes are correct. Original returns, by contrast, can be processed largely by automated systems if they contain no errors or red flags.

The IRS also cross-checks amended returns against the original return you filed. If you claimed a refund on your original return and your amended return changes that refund amount, the IRS verifies the math and the supporting documents before releasing any money. This verification step is what creates the delay.

What Happens During the Processing Period

When you file an amended return, the IRS first checks whether it was filed correctly — that you used the right form (Form 1040-X for federal income tax), included all required signatures, and provided the information needed to match your return to your tax account. If anything is missing, the IRS will mail you a notice asking for the missing information.

Next, the IRS reviews the changes you made. If you reduced your income or increased your deductions, the IRS may request documentation to support those changes. If you increased your income or reduced deductions, the IRS usually processes the return without additional questions, since you are paying more tax or taking less back.

Finally, if your amended return results in a refund, the IRS issues that refund by check or direct deposit, depending on how you requested it. Refunds from amended returns are issued separately from your original refund, so you will receive two payments if both your original and amended returns resulted in refunds.

How to File an Amended Return to Speed Up Processing

File electronically rather than by mail. Electronic filing reduces processing time by roughly half compared to paper filing. You can file electronically through tax software, a tax professional, or a CPA. The software or professional will submit your Form 1040-X directly to the IRS.

Include all required documentation with your amended return. If you are claiming a deduction you did not claim on your original return, attach the receipts or statements that support it. If you are reporting additional income, include the forms that document that income (such as a corrected W-2 or 1099). Providing documentation upfront prevents the IRS from mailing you a request for information later, which would delay your refund.

File your amended return as soon as you discover the error. Do not wait until the last day of the filing season. The IRS processes returns in the order received, so filing early puts your return ahead of the thousands of amended returns filed in March and April.

Refunds From Amended Returns

If your amended return results in a refund, the IRS will issue it after processing is complete. The refund is issued separately from any refund you received on your original return. If you requested direct deposit on your amended return, the refund will be deposited to the bank account you provided. If you requested a check, the IRS will mail it to the address on file.

Refunds from amended returns are subject to the same offset rules as original refunds. If you owe back taxes, child support, or student loans, the IRS may use your refund to pay down those debts before sending you the remaining balance. The IRS will mail you a notice if your refund is offset.

Interest accrues on refunds that are delayed beyond 45 days from the date you filed your amended return. If processing takes longer than 45 days and you are owed a refund, the IRS will pay you interest on that refund at the rate set by law for that quarter. You do not need to request this interest — it is calculated and included automatically.

What to Do If Your Amended Return Is Taking Longer Than Expected

Check the status of your amended return using the Where's My Amended Return tool on IRS.gov. This tool shows whether the IRS has received your return and whether it is still being processed or has been completed. If the tool shows your return is still in process after 12 weeks (for paper) or 8 weeks (for electronic), contact the IRS.

Call the IRS at 1-800-829-1040 to speak with a representative. Have your Social Security number, filing status, and the amount of the refund or tax owed ready. The representative can look up your return in the system and tell you whether it is delayed and why. If there is a problem — such as a missing signature or incomplete information — the representative can tell you what to send to resolve it.

If you filed through a tax professional or software provider, contact them first. They may be able to check the status using their own IRS account or provide you with a confirmation number that will help the IRS locate your return quickly.

Frequently Asked Questions

Can I file an amended return if I already received my refund?

Yes. You can file an amended return at any time within three years of the original filing deadline. If you already received a refund and your amended return shows you owe additional tax, you will need to pay that amount. If your amended return shows you are owed a larger refund, the IRS will issue the difference.

Do I need to file an amended return if I made a small error that does not change my tax?

No. If the error does not change the amount of tax you owe or the refund you receive, you do not need to file an amended return. However, if the error affects your tax liability in any way — even by a dollar — you should file an amended return to correct it.

What if I filed my amended return by mail and it has been more than 12 weeks?

Use the Where's My Amended Return tool to check the status. If the tool shows the IRS has not received your return, it may have been lost in the mail. Contact the IRS at 1-800-829-1040 with your confirmation number or filing details. If the tool shows the return is still processing, the IRS may be requesting additional information by mail.

Will filing an amended return trigger an audit?

Filing an amended return does not automatically trigger an audit. However, if your amended return reports significantly different income or deductions than your original return, the IRS may request documentation to support those changes. This is a verification request, not an audit, and most are resolved by mail.

Can I amend an amended return?

Yes. If you discover an error in your amended return, you can file another amended return to correct it. File it the same way you filed the first amended return — using Form 1040-X and following the same process. The IRS will process the second amended return and apply the corrections to your account.
