4.)Frequently Asked Questions about Splitting Federal Income\Ref

You have several options for receiving your federal income tax refund. You can: •Split your direct deposit refund among two or three different accounts, with up to three different U.S. financial institutions;
•Direct deposit your refund into a single checking or savings account; or
•Receive your refund in a paper check.
•Buy up to $5,000 in U.S. Series I Savings Bonds with your refund.
Splitting your refund is easy. Use IRS’ (Including Savings Bond Purchases) Form 8888, Allocation of Refund (Including Savings Bond Purchases), to split your refund among two or three different accounts. Form 8888 is not required if you want IRS to direct deposit your refund into a single account; you can use the direct deposit line on Forms 1040, 1040A or 1040EZ.
With split refunds, you have a convenient option for managing your money — sending some of your refund to an account for immediate use and some for future savings — teamed with the speed and safety of direct deposit. It’s a win-win.
