You can change the bank account for your tax refund only in a short window before the IRS posts your return to its processing system, or later through a CP53E notice if the bank rejects the deposit. Once the return is posted, the routing and account numbers are locked, and neither a phone call nor an amended return will move the refund to a different account.
The Short Window Right After Filing
If you just filed and immediately noticed a wrong routing or account number, call the IRS at 800-829-1040 (Monday through Friday, 7 a.m. to 7 p.m.) and ask them to stop the direct deposit before it goes out. This works only if your return has not yet been posted to the processing system.1Internal Revenue Service. Refund Inquiries 18
The window is narrow. For e-filed returns, posting can happen within hours of acceptance, so once your tax software shows “Accepted,” the clock is already running. The Where’s My Refund tool on irs.gov will tell you whether the return has been received or is being processed, but it cannot change any banking details itself.2Internal Revenue Service. Refund Inquiries If you catch the mistake within minutes of filing, call right away. If a day or two has already passed, assume the return is posted and read on.
Why It’s Locked Once the Return Is Posted
After posting, the IRS has no mechanism to update your routing or account number. That holds whether you call, write, or visit a Taxpayer Assistance Center.3Internal Revenue Service. Frequently Asked Questions About Splitting Federal Income Tax Refunds The lockdown exists to keep criminals from rerouting refunds after a return is filed, and it applies to honest typos and closed accounts the same way.
Filing an amended return will not redirect the original refund either. Form 1040-X can carry direct deposit instructions, but those only apply to any additional refund the amendment itself generates, not to money already in the pipeline. Paper-filed amended returns cannot use direct deposit at all; that additional refund arrives as a check.4Internal Revenue Service. Instructions for Form 1040-X
So if the window closed, the practical question is no longer how to change the account. It is what happens when the deposit fails, and what you can do at that point.
The CP53E Notice: Your Real Second Chance in 2026
Starting in 2026, when a direct deposit is rejected or flagged, the IRS mails a CP53E notice giving you 30 days to log into your IRS online account and enter new or updated banking information. The system allows one update per notice, so enter the correct numbers the first time.5Internal Revenue Service. Understanding Your CP53E Notice
If the second deposit goes through, the refund typically arrives within two to five days after the status updates online. If it fails again, or if you do nothing within 30 days, the IRS issues a paper check about six weeks after the original notice, assuming nothing else on the return needs attention.6Internal Revenue Service. Questions and Answers About Executive Order 14247
Not every rejected deposit follows the CP53E path. In some processing situations, the IRS instead sends a CP53C notice, which skips the online update option and goes straight to internal research before issuing a paper check. The CP53C timeline can stretch to 10 weeks.7Internal Revenue Service. Understanding Your CP53C Notice
Banks reject deposits for a handful of reasons: the account is closed, the account number does not match any active record, or the name on the deposit does not match the account holder. When any of these happen, the funds are sent back to the IRS automatically, which is what triggers the notice in the first place.7Internal Revenue Service. Understanding Your CP53C Notice
If the Money Landed in Someone Else’s Account
A different problem arises when the routing and account numbers you entered were valid but belonged to someone else. The deposit went through, just to the wrong person. In that case, call the receiving bank first. Federal rules require banks to return ACH payments when the name on the deposit does not match the account holder, and the bank should send the funds back to the IRS.8Bureau of the Fiscal Service. A Guide to Federal Government ACH Payments (Green Book)
If two weeks pass without resolution, file Form 3911 (Taxpayer Statement Regarding Refund) to open a refund trace. Once the trace starts, the bank has up to 90 days to respond, and the full process can take up to 120 days. The trace is the formal mechanism that forces the bank to account for the money.1Internal Revenue Service. Refund Inquiries 18
When the funds come back, the IRS generally reissues the refund as a paper check to your last known address, not as a fresh direct deposit.2Internal Revenue Service. Refund Inquiries The IRS is also explicit that it is not liable for a lost refund caused by incorrect account information you provided.9Internal Revenue Service. Form 8888 – Allocation of Refund
If Someone Filed a Fake Return in Your Name
If you suspect a thief filed a return using your Social Security number and sent your refund to their own account, that is tax-related identity theft, and the process is different. File Form 14039 (Identity Theft Affidavit) with the IRS. Online submission at irs.gov is preferred; you can also fax it to 855-807-5720 or mail it to the IRS in Fresno, California.10Internal Revenue Service. Identity Theft Affidavit – Form 14039
If identity theft is blocking you from e-filing your real return, attach Form 14039 to the back of a paper return and mail them together. Do not send duplicate copies of the form, which slows things down. Identity theft cases go to specialized IRS teams, and resolution usually takes several months before a legitimate refund is reissued.11Internal Revenue Service. IRS Identity Theft Victim Assistance: How It Works
Update Your Address, Because the Fallback Is a Paper Check
Every path other than a successful direct deposit ends the same way: a paper check mailed to the address on your most recent return. If you have moved, that check could go to your old address. USPS mail forwarding helps, but not every post office forwards government checks, so it is not a reliable safety net on its own.12Internal Revenue Service. Address Changes
To update your address with the IRS, file Form 8822 (Change of Address), put the new address on your next return, or send a signed written statement with your full name, Social Security number, and both old and new addresses to the IRS center where you last filed. Allow four to six weeks for the change to take effect, so if you know a paper check may be on the way, start now.12Internal Revenue Service. Address Changes
