You may be getting a second refund because the IRS found an error on your original return, you filed an amended return, or you received a payment you didn't expect that turned out to be refundable.
A second refund usually means one of three things: the IRS corrected something on the return you already filed, you filed Form 1040-X (Amended U.S. Individual Income Tax Return) to claim money you missed the first time, or you received a credit or payment from the government that reduced what you owe and created a new refund balance. The timing and method depend on which one happened.
The most common reason is an IRS correction. The agency processes millions of returns and catches errors—missing income, wrong filing status, math mistakes, duplicate withholding claims. When they find one, they fix it, recalculate what you owe or what you're owed, and send you the difference. You don't have to do anything; the IRS initiates the correction and sends you a notice explaining what changed.
Key Takeaways
- The IRS may have corrected an error on your original return and is sending you the additional refund without you asking.
- If you filed an amended return (Form 1040-X), a second refund means the IRS approved your changes and is sending the extra money you claimed.
- Some government credits or payments—like a recovery rebate credit or a prior-year adjustment—can create a new refund even after you've already received one.
- Check your IRS account online or look for a notice in the mail to confirm which type of refund this is and when it will arrive.
- A second refund is not a mistake on your part and does not require you to return the first one.
IRS corrections to your original return
When the IRS processes your return, they run it through automated checks and sometimes through manual review. If they spot a discrepancy—a W-2 that doesn't match your reported income, a dependent claimed twice, a math error, or a credit you shouldn't have claimed—they correct it and recalculate your refund or balance due.
You'll receive a notice in the mail (usually Form 556, Notice of Deficiency, or a similar letter) that explains what the IRS changed and why. The notice will show the original refund amount, the correction, and the new refund amount. If the correction increases your refund, you'll receive the additional money by mail or direct deposit, depending on how you received the first refund.
This process can take several weeks to several months after you file, depending on how busy the IRS is and how complex the correction is. You don't need to respond unless the notice asks you to provide documentation or disagrees with the change.
You filed an amended return and the IRS approved it
If you filed Form 1040-X after your original return, you were claiming additional deductions, credits, or income adjustments that you missed or that changed. When the IRS processes the amended return, they recalculate your tax liability and send you the additional refund if you're owed one.
Amended returns take longer to process than original returns—typically 8 to 12 weeks, though it can stretch to 16 weeks or more during busy periods. You can track the status of your amended return using the IRS Where's My Amended Return tool on IRS.gov, or by calling the IRS at 1-800-829-1040 and providing your Social Security number and the tax year.
The IRS will send you a notice confirming the changes they made and the new refund amount. If you had direct deposit set up on your original return, the amended refund will go to the same account. If you requested a check, it will arrive by mail.
A credit or payment changed your refund balance
Sometimes a second refund appears because you received a government payment or credit after you filed that reduced what you owe. Common examples include a recovery rebate credit (if you didn't receive the full amount of a stimulus payment), a child tax credit adjustment, an earned income tax credit correction, or a prior-year tax balance that was applied to your current year.
If you received a stimulus payment in 2021 or 2022 but didn't report it correctly on your return, the IRS may have adjusted your refund when they processed your return. The same applies if you were may have access to to a child tax credit but didn't claim it, or if you received a credit in error and the IRS corrected it in your favor.
These adjustments show up as a second refund because they happen after your original return was processed and your first refund was sent. The IRS will include an explanation in the notice they send you.
How to confirm what type of refund you're receiving
The fastest way to find out is to check your IRS account online. Go to IRS.gov, select "View your tax account," and sign in with your Social Security number and other identifying information. Your account will show all refunds issued to you, including the date each one was sent and the amount.
You can also look for a notice in the mail from the IRS. These notices explain what changed and why. Keep any notice you receive—you may need it for your records or if you have questions later.
If you filed an amended return, you can check its status separately using the Where's My Amended Return tool on IRS.gov. Enter your Social Security number, filing status, and the exact refund amount from your amended return to see where it is in the queue.
When the second refund will arrive
Timing depends on the type of refund. If the IRS corrected your original return, the additional refund typically arrives within 2 to 4 weeks of the notice date, though it can take longer if the correction was complex or if the IRS is processing a high volume of returns.
If you filed an amended return, the refund arrives 8 to 12 weeks after the IRS receives it, or longer during peak tax season (January through May). If you requested a check instead of direct deposit, add another 1 to 2 weeks for mail delivery.
If the second refund is from a credit or payment adjustment, timing varies. Some adjustments are processed quickly (2 to 4 weeks), while others take longer if they require manual review.
You can check the expected delivery date in your IRS account online. If the refund doesn't arrive within the timeframe shown, contact the IRS at 1-800-829-1040 or use the Where's My Refund tool to investigate.
What to do if the second refund seems wrong
If you disagree with the IRS correction or the second refund amount, you have the right to dispute it. First, review the notice the IRS sent you carefully. It will explain exactly what changed and why. If you believe the IRS made an error, gather documentation (receipts, W-2s, 1099s, prior-year returns) that supports your position.
You can respond to the IRS notice by mail or by calling 1-800-829-1040. Include a clear explanation of why you disagree and attach copies of supporting documents. The IRS will review your response and send you a final information.
If you filed an amended return and the IRS rejected it or made changes you don't agree with, you can file another amended return or request an appeals conference. The notice you receive will explain your options.
Frequently Asked Questions
Do I have to return the first refund if I'm getting a second one?
No. Both refunds are yours. The first refund was correct based on the information available at the time. The second refund is an adjustment or correction that happened later. You do not owe any money back.
Can I get a second refund if I already spent the first one?
Yes. The second refund is independent of the first. Whether you've spent the first refund has no effect on your right to receive the second one or on the amount.
What if I received a second refund I didn't expect and didn't file an amended return?
The IRS likely corrected an error on your original return. Check your IRS account online or wait for a notice in the mail explaining the correction. If you disagree with it, you can contact the IRS to dispute it.
How long do I have to report a second refund I think is a mistake?
If you believe you received a refund in error, contact the IRS as soon as possible. There is no strict deadline, but the sooner you report it, the sooner the IRS can investigate. Call 1-800-829-1040 or respond to any notice the IRS sends you.
Will a second refund affect my taxes next year?
No. A second refund is a correction or adjustment to the year it was issued for. It does not change your tax situation for the following year unless the correction involved income or credits that carry forward.
