What is Form 8888?
Tax Form 8888, Allocation of Refund, lets you split your federal tax refund into two or three different accounts using direct deposit. Instead of sending your entire refund to one place, you can divide it between checking, savings, or even retirement accounts like a traditional IRA, Roth IRA, SEP IRA, HSA, or Coverdell ESA. For example, you could send half to your savings account and half to your IRA — all in one step when you file your return.
What is Form 8888 used for?
Form 8888 is used to:
- Split your tax refund across two or three accounts via direct deposit.
- Direct portions of your refund to different account types — checking, savings, retirement, or health savings accounts.
Note: The option to purchase U.S. Series I Savings Bonds through Form 8888 has been discontinued.
How to fill out Form 8888
1. Enter your personal information:
- Your name(s) and Social Security number, exactly as they appear on your tax return.
2. Set up your first deposit (Line 1):
- Line 1a: The dollar amount you want in this account (minimum $1).
- Line 1b: The bank's 9-digit routing number (first two digits must be 01–12 or 21–32).
- Line 1c: Check either Checking or Savings — only one.
- Line 1d: Your account number (up to 17 characters, including hyphens, skipping spaces and symbols).
3. Set up your second deposit (Line 2):
- Fill in lines 2a–2d the same way — amount, routing number, account type, and account number for your second account.
4. Set up your third deposit (Line 3, optional):
- Only fill this in if you're splitting your refund three ways. Same format as above.
5. Add it all up (Line 5):
- Add lines 1a, 2a, and 3a together. This total must match your exact refund amount on your tax return. If it doesn't, your refund may be delayed.
6. Double-check and attach:
- Verify all routing and account numbers with your bank. Never cross out or white out anything on the form — the IRS will reject it. Attach Form 8888 to your Form 1040 when you file.
Who is required to fill out Form 8888?
You only need Form 8888 if you want your refund deposited into more than one account. If your entire refund is going to a single account, skip this form and just enter your direct deposit details on your tax return.
When is Form 8888 not required?
You don't need Form 8888 if:
- Your entire refund is going to one account — enter the direct deposit info directly on your tax return.
- You'd rather receive a paper check — though starting October 2025, the IRS is generally phasing out paper refund checks.
- You're filing Form 8379 (Injured Spouse Allocation) — you cannot split your refund into multiple accounts in that case.
When is Form 8888 due?
Form 8888 is attached to your tax return, so the deadline is the same — typically April 15. If you file an extension, submit Form 8888 when you file your completed return.
