The second refund usually arrives within two to three weeks after the IRS accepts your amended return

If you filed an amended tax return using Form 1040-X, the IRS processes it more slowly than an original return. Most second refunds arrive between 14 and 21 days after the IRS accepts your amendment, though some take up to 12 weeks depending on whether the IRS needs to review your changes or correct errors in your original filing.

The timeline depends on three things: whether you filed electronically or by mail, whether the IRS finds issues that need investigation, and how busy the IRS is during that tax season. An electronic amendment filed in April moves faster than one filed in August, because the IRS has fewer returns to process in late summer.

You can track your refund using the IRS Where's My Refund tool on IRS.gov, which updates every 24 hours. The tool will tell you the exact status — whether the IRS is still processing, whether it approved your amendment, or whether there is a problem holding up payment.

Key Takeaways

  • Amended returns processed electronically typically receive refunds within two to three weeks, while paper amendments can take up to 12 weeks.
  • The IRS processes amended returns more slowly than original returns because each change must be reviewed by hand.
  • You can check the status of your amended return refund using the Where's My Refund tool on IRS.gov, which updates daily.
  • If the IRS finds errors or inconsistencies in your amendment, it may contact you before sending the refund, which adds time.
  • Refunds are typically sent by direct deposit if you provided banking information, or by check if you did not.

Why amended returns take longer than original returns

The IRS processes original tax returns through automated systems that scan and sort thousands of returns per hour. Amended returns cannot use that same automation because each one involves a human reviewer comparing your original return to your new one, checking that the changes make sense, and verifying that you corrected the right items.

This manual review is why the IRS estimates 8 to 12 weeks for amended returns, even though most arrive faster. The IRS publishes this longer estimate to account for returns that need extra investigation — for example, if you claimed a large deduction you did not claim before, or if you changed your filing status.

During peak tax season (February through April), the IRS has thousands of amended returns in queue, so even straightforward amendments can take longer. Filing your amendment in May or June usually means faster processing than filing in March, because fewer people are amending at that time.

Direct deposit versus check delivery

If you provided your bank account number on your original return, the IRS will send your amended refund by direct deposit to that same account. Direct deposit is faster and more reliable than a check — the money typically appears in your account within one business day of the IRS releasing the refund.

If you did not provide banking information on your original return, or if you want the refund sent to a different account, you must include your routing number and account number on Form 1040-X. Without this information, the IRS will mail you a check, which can take an additional 7 to 10 business days to arrive after the IRS processes your amendment.

Checks are also more likely to be lost or delayed in the mail. If you are amending your return, adding your bank account information is the fastest way to receive your refund.

What delays a second refund

The most common delay is an error on your amended return itself. If you made a math mistake, listed the wrong income figure, or did not sign Form 1040-X, the IRS will send you a notice asking you to correct it. This adds 30 to 60 days to your timeline because you have to respond, and then the IRS has to reprocess your amendment.

A second common delay happens when your amended return conflicts with information the IRS already has on file. For example, if you claim a dependent on your amended return but did not claim that person on your original return, the IRS may contact your employer or the dependent's school to verify the relationship. This verification can take 4 to 8 weeks.

The IRS also delays refunds when it suspects identity theft or fraud. If someone else filed a return using your Social Security number, or if your amended return looks unusual compared to your past returns, the IRS will hold the refund while it investigates. You will receive a letter explaining the hold, and the investigation typically takes 60 to 90 days.

How to check your refund status

Go to IRS.gov and click on "Where's My Refund?" You will need your Social Security number, filing status, and the exact refund amount from your amended return. The tool updates once per day, usually overnight, so checking multiple times in one day will not give you new information.

The tool will show one of four messages: "We received your return" (still processing), "We approved your return" (refund is being prepared), "Your refund was sent" (refund is on the way), or "We need more information" (the IRS found a problem). If you see the last message, the IRS will have sent you a letter with instructions on what to do next.

If the Where's My Refund tool says your refund was sent more than 21 days ago and you have not received it, contact the IRS at 1-800-829-1040. Have your Social Security number, filing status, and the refund amount ready. The IRS can tell you whether the refund was sent by check or direct deposit, and if it was sent by check, whether it has been cashed.

Amended returns filed by mail take longer

If you mailed Form 1040-X instead of filing electronically, add 2 to 4 weeks to the processing time. The IRS has to receive your amendment, scan it into the system, and verify that it matches your original return before a reviewer can examine it. Mail processing centers are slower than electronic filing systems, especially during peak season.

The IRS recommends filing amended returns electronically using tax software or a tax professional. If you must mail your amendment, send it certified mail with return receipt so you have proof the IRS received it. Keep the receipt until you see your refund arrive.

What to do if your refund is taking longer than expected

If more than 21 days have passed since the IRS accepted your amended return and the Where's My Refund tool still shows "processing," contact the IRS at 1-800-829-1040. Have your Social Security number, filing status, and the exact refund amount ready. The IRS can tell you whether your amendment is still in queue or whether something is holding it up.

If the IRS tells you there is a problem, ask what information or documents you need to provide. Some issues can be resolved over the phone; others require you to mail additional paperwork. If you need to mail something, ask for the specific address and whether you should use certified mail.

If you amended your return because you owed money instead of receiving a refund, the timeline is different — the IRS will not send you anything, but your account will be updated and any overpayment will be applied to next year's taxes or refunded if you request it.

Frequently Asked Questions

Can I check my amended return status online the same way I check my original return?

Yes, use the same Where's My Refund tool on IRS.gov. It tracks both original and amended returns. The tool updates once per day, so check back tomorrow if it says "still processing" today.

What if I filed my amended return electronically but the IRS says it never received it?

Ask your tax software or tax professional for a confirmation number or acceptance receipt. The IRS can search their system using that number. If the IRS truly never received it, you will need to file again, and the second filing date becomes your official amendment date.

Does the IRS charge a fee to process an amended return?

No. The IRS does not charge a fee for filing Form 1040-X. However, if you paid a tax professional to prepare your amendment, that professional may charge a fee for their work.

If I amended my return to claim a refundable tax credit, does that change how long the refund takes?

Yes, refundable credits like the Earned Income Tax Credit can add time because the IRS verifies your income and dependent information more carefully. Expect 4 to 8 weeks instead of 2 to 3 weeks if your amendment includes a refundable credit you did not claim originally.

What happens if the IRS sends my refund check but I never receive it?

Call the IRS at 1-800-829-1040 and tell them the check was lost. The IRS can issue a replacement check or send the refund by direct deposit if you provide your bank account information. A replacement check usually arrives within 4 to 6 weeks.
