Putting the wrong routing number on your tax return usually delays your refund rather than losing it. The receiving bank rejects the deposit, the money bounces back to the IRS, and you either get a paper check or a chance to fix your banking details online. Starting in the 2026 filing season, the IRS may send a CP53E notice giving you 30 days to update your bank information through your IRS online account before it falls back to a check.1Internal Revenue Service. Understanding Your CP53E Notice The harder case is when the wrong number happens to match a real account belonging to someone else. That one, the IRS treats as your problem to sort out with the bank.
If You Catch It Before the Return Processes
There’s a narrow window to stop the deposit. If your return has not yet posted to the IRS system, call 800-829-1040 and ask the IRS to stop the direct deposit before it goes out.2Internal Revenue Service. Refund Inquiries 18 Electronic returns typically post within 24 to 48 hours of acceptance, so move fast. Paper returns give you a little more time. Once the return posts and the refund is scheduled, the IRS cannot change the bank account through a phone call or amended return.
What Happens When the Bank Rejects the Deposit
The IRS sends refunds through the Automated Clearing House network. A wrong routing number often doesn’t match any real bank, so the ACH network rejects the transaction outright. A wrong account number is trickier: the routing number sends the money to the right bank, but the account either doesn’t exist or the name on the refund doesn’t match the account holder. Banks run name-matching checks, and a mismatch causes the bank to return the full amount to the Treasury.
Once the IRS receives the returned funds, it cancels the electronic payment. From there you’ll either get a CP53E notice or a paper check. Plan on roughly six extra weeks in your refund timeline.3Taxpayer Advocate Service. Direct Deposit Changes for 2026 Could Affect How and When You Get Your Refund
The CP53E Notice and Your 30-Day Window
The IRS now sends a CP53E notice when direct deposit information is missing or rejected. The notice gives you 30 days to log into your IRS online account and provide new or corrected bank details.1Internal Revenue Service. Understanding Your CP53E Notice That’s a real change from prior years, when a failed deposit meant waiting for a paper check with no way to redirect the money electronically.
A few things to know:
- You can only update your bank account through your IRS online account. IRS employees cannot take direct deposit information over the phone or in person.4Internal Revenue Service. Questions and Answers About Executive Order 14247
- You get one chance. There is no second attempt if you enter the wrong information again.1Internal Revenue Service. Understanding Your CP53E Notice
- If you don’t respond within 30 days, the IRS issues a paper check six weeks from the notice date.1Internal Revenue Service. Understanding Your CP53E Notice
The IRS will only contact you about the CP53E notice through U.S. mail. Any phone call, text, or email claiming to be the IRS asking for your banking details is a scam.4Internal Revenue Service. Questions and Answers About Executive Order 14247
If the Money Landed in Someone Else’s Account
The worst case is entering a routing and account number that happens to match a real, active account belonging to someone else. If the bank accepts the deposit, the IRS considers the refund delivered and has no authority to pull the money back. The agency puts it plainly: it assumes no responsibility for taxpayer or tax preparer error in entering bank details.2Internal Revenue Service. Refund Inquiries 18
Contact the bank where the money was deposited and explain the situation. You’ll need to work directly with the financial institution to recover the funds.2Internal Revenue Service. Refund Inquiries 18 If five calendar days pass after contacting the bank with no resolution, file Form 3911 (Taxpayer Statement Regarding Refund) to initiate a formal refund trace. The trace lets the IRS contact the bank on your behalf and ask that the funds be returned.5Internal Revenue Service. About Form 3911, Taxpayer Statement Regarding Refund
Banks have up to 90 days from the date of the trace to respond, and full resolution can take up to 120 days.6Internal Revenue Service. Internal Revenue Manual 21.4.2 – Refund Trace and Limited Payability If the bank recovers the funds, the IRS sends you a notice explaining your next steps. If the funds are gone or the bank refuses to return them, the IRS cannot compel the bank to act. The matter then becomes a civil dispute between you and the financial institution or the person who received the money.2Internal Revenue Service. Refund Inquiries 18 That’s the scenario where people sometimes need a lawyer.
Tracking Your Refund and Keeping Your Address Current
The “Where’s My Refund?” tool at irs.gov is the fastest way to see what’s happening. If your direct deposit failed, the tool updates to reflect the problem and shows your next steps, including whether a CP53E notice has been issued.4Internal Revenue Service. Questions and Answers About Executive Order 14247 You can also check your IRS online account directly to see whether a notice is waiting.7Internal Revenue Service. Refund Inquiries 25
If you’ve moved since filing, update your address with Form 8822, a signed written statement listing your old and new addresses, or a call to the IRS.8Internal Revenue Service. Address Changes A paper check goes to the last address the IRS has on file.
Split Refunds, Joint Returns, and Preparer Errors
If you used Form 8888 to split your refund across multiple accounts, a bad number for one account triggers the same rejection process for the affected portion.2Internal Revenue Service. Refund Inquiries 18 Form 8888 also has a quirk worth knowing: if any processing delay occurs, the IRS may deposit your entire refund into the last valid account you listed rather than splitting it. The instructions advise choosing a last account you’d be comfortable receiving the full refund.9Internal Revenue Service. Form 8888, Allocation of Refund
For married couples filing jointly, the IRS can only deposit a refund electronically into an account held in one or both spouses’ names, or a joint account.10Taxpayer Advocate Service. Direct Deposit Refunds and Refund Offsets If the account belongs to someone outside the marriage, the bank may reject the deposit on name-matching grounds even when the routing number is correct.
If a tax preparer entered the wrong bank information, the IRS treats the error exactly like your own. You may have a separate claim against the preparer, but it doesn’t change how the IRS handles your refund. One related situation catches people off guard: if your preparer set up a Refund Anticipation Loan or Refund Anticipation Check, the refund was routed to the preparer’s financial institution first, not directly to your bank. If something goes wrong there, your first call should be to the preparer’s institution, not the IRS.2Internal Revenue Service. Refund Inquiries 18
The Three-Deposit Limit
One more wrinkle that can look like a wrong-account problem: the IRS limits direct deposits to three refunds per bank account per year. A fourth refund directed to the same account is automatically converted to a paper check.11Internal Revenue Service. Direct Deposit Limits This mostly affects households where several members file to the same account. You’ll get a notice explaining the conversion, and the paper check typically arrives within about four weeks.
