You can link your checking account to the IRS through their online portal or by mail, but the method depends on what you're trying to do

The IRS does not have a single "add your account" process that works for everything. What you're actually doing depends on your reason: setting up direct deposit for a refund, authorizing an electronic payment toward taxes you owe, or updating account information on file for an existing arrangement. Each path uses different tools and takes different amounts of time. The fastest route is usually the IRS Direct Pay system if you owe taxes, or the refund information you enter when you file if you expect money back.

If you're already in the middle of changing account holders on an existing arrangement—like removing a spouse from a joint account or switching to a new bank—the steps are different again. You'll need to contact the IRS directly or file an amended return, depending on what's already on file.

Key Takeaways

  • Direct deposit for refunds is set up when you file your tax return, not through a separate IRS account portal.
  • IRS Direct Pay lets you authorize a one-time or recurring tax payment from your checking account without creating a login.
  • If you need to change account information on an existing arrangement, you must contact the IRS by phone or mail—there is no online update option.
  • The IRS accepts checking account details only; they do not accept savings accounts or money market accounts for payments or refunds.
  • You will need your routing number and account number, both found on the bottom left of your checks or through your bank's website.

Adding a checking account for a tax refund

When you file your tax return, you enter your checking account information directly on the form or through tax software. The IRS uses this information to deposit your refund electronically. You do not need to log into an IRS account or pre-register your bank details. The account information you provide on your return is used only for that refund and is not stored for future use.

You will need your routing number and account number. Both appear on the bottom left of any check you have from that account. If you do not have a check, log into your bank's website or call the bank's customer service line and ask for both numbers. The routing number is nine digits; the account number is usually 10 to 12 digits but varies by bank.

When you file, you will also choose whether the account is a checking or savings account. The IRS accepts checking accounts for refunds. Some tax software will accept savings accounts, but the IRS will reject the deposit if the account type is wrong, and your refund will be delayed while the IRS contacts you to correct it.

Setting up a payment from your checking account using IRS Direct Pay

IRS Direct Pay is the official system for paying taxes owed directly from your checking account. You do not need to create an IRS login or account. You visit IRS.gov/payments, enter your Social Security number or Employer Identification Number, and authorize a payment. The system guides you through entering your routing and account numbers, the amount you want to pay, and the date you want the money withdrawn.

Payments are free. The IRS does not charge a fee, and neither does the bank. The withdrawal usually happens within one to three business days of the date you choose. You can set up a one-time payment or schedule recurring payments if you have a payment plan with the IRS.

You do not need to be logged into an IRS account to use Direct Pay. Each time you visit, you enter your identifying information fresh. This means you also do not have a record of past payments saved in an online portal—you will need to keep your own confirmation number, which the system provides at the end of each transaction.

Changing your checking account on an existing IRS arrangement

If you already have a payment plan, an installment agreement, or a refund on file with the IRS and you need to change the account information, you cannot do this online. You must contact the IRS directly.

Call the IRS at 1-800-829-1040 (individual taxpayers) or 1-800-829-4933 (business taxpayers). Have your Social Security number or EIN, your current account information, and your new account information ready. The IRS representative will update your file. This usually takes effect within one to two business days, though during tax season (January through April) it may take longer.

Alternatively, you can mail a written request to the IRS address for your state. The request must include your name, Social Security number, the old account information, the new account information, and your signature. Mail it to the address listed on your most recent IRS notice or bill. Processing by mail typically takes four to six weeks.

What happens if you enter the wrong account number

If you file a return with an incorrect account number, the IRS will attempt the deposit. If the account does not exist or the number does not match the routing number you provided, the bank will reject the deposit and return it to the IRS. The IRS will then contact you by mail to ask for the correct information. Your refund will be delayed by at least two to four weeks while this happens.

If you realize the error before you file, correct it in your tax software or on the form before submitting. If you have already filed and notice the error, contact the IRS at 1-800-829-1040 to provide the correct account information. Doing this before the IRS attempts the deposit can prevent the delay.

For payments made through IRS Direct Pay, the system validates your routing and account numbers before you submit. If there is a mismatch, the system will reject the payment and ask you to re-enter the information. This happens before any money leaves your account.

Account types the IRS will and will not accept

The IRS accepts checking accounts only for both refunds and payments. They do not accept savings accounts, money market accounts, or prepaid debit cards, even if those accounts have routing and account numbers.

If you attempt to use a savings account, the bank may still process the transaction, but the IRS may reject it if they verify the account type during processing. This is more likely to happen with refunds than with payments. If your refund is rejected because of the account type, the IRS will mail you a check instead, adding two to three weeks to the time you receive your money.

If you do not have a checking account, you can request that the IRS mail you a check instead. When you file your return, select the option for a paper check rather than direct deposit. For payments, you can use a credit card or debit card through a third-party payment processor, though these services charge a fee of 1.87% to 2.35% of the payment amount.

Frequently Asked Questions

Do I need to create an IRS account to add my checking account?

No. For refunds, you enter your account information when you file your return. For payments through IRS Direct Pay, you do not need an account—you enter your information each time you visit the payment page. If you have an existing payment plan or arrangement, you contact the IRS by phone or mail to update account information.

Can I add my spouse's checking account to my tax return?

Only if the refund is being deposited to a joint account that you both own. If you want the refund to go to your spouse's individual account, you cannot do that through your return. Your spouse would need to file their own return or you would need to request a check and have your spouse deposit it. For a payment plan, both spouses can be listed, but the account must be one that both can access.

What if my bank is closed when the IRS tries to deposit my refund?

The IRS does not deposit on weekends or federal holidays. If you choose a deposit date that falls on a weekend or holiday, the IRS will process it on the next business day. Your bank will receive the deposit and post it to your account according to their own schedule, usually within one business day of receipt.

Can I use the same checking account for multiple tax returns or payments?

Yes. You can use the same account for your federal return, your state return, and IRS Direct Pay payments. Each transaction is separate, so you enter the account information each time. The IRS does not store your account details between transactions.

What if I close my checking account after I file my return?

Contact the IRS when ready at 1-800-829-1040 and provide your new account information. If the IRS attempts to deposit to the closed account, the bank will reject it and return it. The IRS will then mail you a check, which adds two to three weeks. Providing a new account number before the deposit attempt prevents this delay.
