The form you need is IRS Form 8888
Form 8888 is the only IRS form that lets you split your federal tax refund across up to three separate bank accounts or financial institutions. You file it alongside your main tax return — either Form 1040 (individual income tax) or the form your filing status requires. The IRS processes the split automatically once they accept your return; you do not contact them separately to divide the money.
The form itself is straightforward: you list the routing number and account number for each destination, specify how much of your refund goes to each one, and sign it. The amounts can be dollar figures or percentages. Most tax software includes Form 8888 as a built-in option when you reach the refund section, so you may never print or mail a physical form.
You can split your refund into a checking account, savings account, or even an Individual Retirement Account (IRA) contribution — the form works with any account type that accepts electronic deposits. The only requirement is that the account must be in your name or your name and a spouse's name if you file jointly.
Key Takeaways
- Form 8888 divides your federal refund into up to three separate accounts, and you file it with your tax return, not after.
- You need the routing number and account number for each bank or financial institution where you want the money sent.
- Tax software typically includes Form 8888 as a checkbox option in the refund section, so most people never handle a paper form.
- The IRS processes the split automatically; you do not need to contact them or take any action after filing.
- Splitting your refund does not change the amount you receive or trigger any additional fees or taxes.
Where to find your routing and account numbers
Your bank's routing number appears on the bottom left of any check you write, or you can find it on your bank's website under account information or customer service. The account number is the longer string of digits next to the routing number on a check, or you can log into your online banking portal and find it under account details.
If you are splitting between accounts at different banks, each one has its own routing number. Write down the correct routing and account number for each destination before you start your tax return, because entering them wrong means the IRS sends money to the wrong place — and recovering it takes weeks of back-and-forth with your bank and the IRS.
Some people split refunds between a checking account (for when ready spending) and a savings account (to avoid touching it). Others use it to fund an IRA contribution in the same year they file, which counts toward that year's contribution limit. The form does not care what you do with the money once it lands.
How the split actually works on your return
When you file your return with Form 8888, you tell the IRS the total refund amount you expect and how to divide it. For example, if you are owed $3,000 and want $2,000 in your checking account and $1,000 in savings, you enter those two amounts on the form. The IRS calculates the total, confirms it matches your return, and processes both transfers at the same time.
The split happens during normal refund processing, which takes 21 days or longer depending on how you file and whether the IRS needs to verify anything on your return. You do not have to wait for the full refund to arrive in one account and then move it yourself. Both deposits hit their destinations on the same day, or within one business day of each other.
If you file by paper, include the completed Form 8888 in the same envelope as your return. If you file electronically through tax software or a tax professional, the form uploads as part of your return file. Either way, the IRS treats it as a single filing.
What happens if you make a mistake on the form
If you enter a wrong routing or account number, the IRS will send that portion of your refund to the wrong bank. That bank will typically reject the deposit as invalid and return it to the IRS, which then sends it back to you — but this process can take four to eight weeks. During that time, your money sits in limbo.
If you realize the error before you file, delete or correct the information in your tax software and resubmit. If you catch it after filing but before the IRS processes your return, contact the IRS when ready at 1-800-829-1040 to request a halt. Once the refund has been processed, you will have to wait for the rejected deposit to bounce back and then contact the IRS to confirm the correct account information.
The safest approach is to verify each routing and account number twice before you file. Call your bank or log in and screenshot the account details if you are uncertain. A few extra minutes of checking prevents weeks of waiting for a misdirected refund.
Splitting a refund when you file jointly
If you file a joint return with a spouse, both of you can receive portions of the refund in separate accounts. The form does not require that all accounts be in one person's name — you can send part of the refund to your account, part to your spouse's account, and part to a joint account if you have one.
The IRS does not care how you divide the money between spouses; it only requires that each account be in at least one of your names. If you want to send the entire refund to your spouse's account, that is allowed. If you want to split it three ways — your checking, your spouse's savings, and a joint account — that works too.
You both sign the return, but only one of you needs to complete Form 8888. The other spouse does not sign the form separately.
Alternatives if you cannot use Form 8888
Some people file through a tax preparer or software that does not support Form 8888, or they realize they want to split the refund after they have already filed. In those cases, you can request a paper check instead of direct deposit, deposit the full check into one account, and then transfer portions to other accounts yourself. This takes longer — paper checks arrive in 3 to 4 weeks — but it works.
If you have already received your full refund in one account and want to split it now, you can straightforward transfer money between your own accounts. There is no IRS form or process required; you are just moving your own money. This is not a split in the tax sense, but it achieves the same result.
Some tax software does not display Form 8888 as an option if you are filing a simpler return or using a free tier. If you want to split your refund and your software does not offer it, you can read Form 8888 directly from the IRS website, print it, fill it out by hand, and mail it with your paper return. The form is short and the instructions are clear.
Frequently Asked Questions
Can I split my refund into more than three accounts?
No. Form 8888 allows a maximum of three separate deposits. If you need to split into more accounts, you can receive the refund in one account and then transfer portions to the others yourself after the money arrives.
Does splitting my refund reduce the total amount I receive?
No. The split is purely a routing instruction. The IRS calculates your refund once and divides it according to your instructions on Form 8888. You receive the full amount you are owed, just in multiple places instead of one.
What if I want to change the split after I file?
If your return has not been processed yet, contact the IRS at 1-800-829-1040 and ask them to halt processing so you can file an amended return with corrected account information. Once the refund has been processed and deposited, you cannot change where it went — you will have to transfer the money yourself between your own accounts.
Can I use Form 8888 to send part of my refund to someone else's account?
No. All accounts listed on Form 8888 must be in your name or, if you file jointly, in your name or your spouse's name. You cannot send refund money directly to another person's account using this form. If you want to give someone money from your refund, you receive it first and then transfer it to them.
Do I need Form 8888 if I just want direct deposit instead of a check?
No. If you want your entire refund in one account, you enter the routing and account number directly on your main tax return (Form 1040 or equivalent). Form 8888 is only for splitting the refund across multiple accounts.
