The IRS collects your account number from you, not from your bank
The IRS does not pull your checking account number from your bank without your knowledge. You provide it to them—either on your tax return, through a prior refund, or when you set up direct deposit for a payment plan. The IRS keeps that information on file and uses it for future refunds unless you change it.
If you see a refund going to an account you did not authorize, the problem is usually one of three things: someone filed a return using your Social Security number, your tax preparer entered the wrong account details, or you changed banks but did not update your information with the IRS.
Key Takeaways
- You give the IRS your account number when you file your return, either by entering it yourself or through a tax preparer.
- The IRS stores your account number and reuses it for future refunds unless you file a new return with different banking details.
- If a refund went to the wrong account, contact the IRS directly at 800-829-1040 or check your transcript at irs.gov to see what account is on file.
- Tax identity theft—someone filing a return with your SSN—is the most common reason a refund lands in an account you do not recognize.
- You can update your banking information by filing an amended return or calling the IRS, but changes take time to process.
Where the IRS gets your account number from your tax return
When you file a tax return, you enter your checking or savings account number in the direct deposit section. This is a standard field on Form 1040 and most state returns. You can enter it yourself if you file online, or your tax preparer enters it if you file through a tax service or accountant.
The IRS reads that number from your return and stores it in their system. They use it to send your refund by electronic transfer instead of mailing a check. If you file the same way every year, the IRS will send your refund to that same account the following year unless you change it on your new return.
This is why changing banks matters: if you close an old account and open a new one, you must update your account number on your next tax return. If you do not, the IRS will try to send your refund to the closed account, and the bank will reject it.
How the IRS reuses your account number year to year
The IRS maintains a database of taxpayer information, including your account number from the most recent return you filed. When you file a new return the following year, the IRS pre-fills some fields based on what they have on record—though account number is not usually one of them. You have to enter it again.
However, if you do not file a return in a given year but the IRS sends you a refund anyway (for example, if you received a stimulus payment or a recovery rebate), they will use whatever account number is in their system from your last filed return. This is why it is critical to update your account information if you change banks.
You can see what account number the IRS has on file by viewing your tax transcript at irs.gov. Log in to your account, go to "Tax Records," and select "View Account Transcript." The transcript shows the account number from your most recent return.
What happens if someone files a return with your Social Security number
If a refund went to an account you do not recognize, tax identity theft is a real possibility. A criminal can file a return using your Social Security number and their own bank account, and the IRS will send the refund there. You will not know until you file your own return and the IRS rejects it as a duplicate.
To check whether this has happened, pull your tax transcript at irs.gov or call the IRS at 800-829-1040. The transcript will show any returns filed under your SSN, including the account number the refund was sent to. If you see a return you did not file, report it to the IRS immediately and file Form 14039, Identity Theft Affidavit.
The IRS will freeze your account to prevent further fraudulent filings and investigate. This process can take weeks or months, but it protects you from future theft and may recover the stolen refund.
Correcting a refund sent to the wrong account
If your tax preparer entered the wrong account number, or you made a typo when filing, you have a few options. The fastest is to call the IRS at 800-829-1040 and ask them to intercept the refund before it posts. This works only if the refund has not yet been deposited—usually within one to three days of the IRS sending it.
If the refund has already posted to the wrong account, you will need to contact that bank and ask them to reverse the deposit. Provide them with the refund amount and the date it arrived. Most banks can reverse a deposit if you request it within a few days, though some require written authorization from the IRS.
You can also file an amended return using Form 1040-X and enter your correct account number. The IRS will send a new refund to the correct account, but this takes four to six weeks to process. During that time, the original refund may still be sitting in the wrong account.
Updating your account number with the IRS
If you changed banks and want to update your account number before filing your next return, you have limited options. The IRS does not have a form or phone line to update banking information outside of filing a return. Your account number is tied to your tax return, not to your IRS account.
The only way to change it is to file an amended return (Form 1040-X) with your new account number. This tells the IRS to use the new number for any future refunds. Processing takes four to six weeks, so file it well before you expect a refund.
If you are waiting for a refund and have not yet filed, simply enter your current account number when you file. Do not worry about old account numbers on file—the IRS uses the most recent return you submitted.
Why the IRS cannot access your bank account directly
The IRS does not have the technical ability to pull account numbers from your bank. Banks do not share customer account information with the IRS, and the IRS does not have access to banking systems. The only way the IRS gets your account number is if you provide it.
This is actually a protection for you. It means the IRS cannot withdraw money from your account without your permission. They can only deposit refunds into an account you have told them about. If money is being withdrawn from your account by the IRS, it is because you authorized it—for example, by setting up an installment agreement for back taxes.
Frequently Asked Questions
Can the IRS see my bank balance?
No. The IRS cannot access your bank account or see your balance. They can only deposit money into an account you have given them. If the IRS is collecting a debt, they can levy your bank account, but only after a formal notice and demand for payment, and only through a court order or administrative process.
What if I gave the IRS the wrong account number by mistake?
Call the IRS at 800-829-1040 immediately if the refund has not yet been sent. If it has already been deposited to the wrong account, contact that bank and ask them to reverse it. You can also file an amended return with the correct account number, though this takes longer.
Does the IRS share my account number with other agencies?
The IRS does not share your account number with other federal agencies. However, if you owe a federal debt—such as student loans or child support—the Treasury Department can intercept your refund and apply it to that debt. This happens before the refund reaches your account.
How long does it take the IRS to update my account number?
If you file a new return with a different account number, the IRS uses the new number for that refund. If you file an amended return to change your account number, processing takes four to six weeks. The new number applies to future refunds, not past ones.
What should I do if I do not recognize the account number on my tax transcript?
Contact the IRS at 800-829-1040 or file Form 14039 if you suspect identity theft. Request a copy of the return that was filed with that account number. If you did not file it, the IRS will investigate and may recover the refund.
