Getting a tax refund is exciting — but putting it all in one checking account isn’t always the smartest move.
With Form 8888 (Allocation of Refund), you can tell the IRS to divide your refund across multiple bank accounts or even use part of it to purchase U.S. Savings Bonds.

1️⃣ What Is Form 8888?
Form 8888 allows taxpayers to allocate their refund to multiple destinations instead of receiving a single direct deposit.
