Updated October 16, 2026. Quick answer: Form 8888 splits a direct deposit refund between two or three accounts. The instructions say it can send part of a refund to a traditional IRA, Roth IRA or SEP IRA, but not a SIMPLE IRA, and that the filer must tell the trustee or custodian which year the deposit is for, unless the trustee or custodian won’t accept a deposit for the prior year. The savings bond purchase feature has been discontinued. A refund going to a single account does not use this form.

What Form 8888 does
The form is attached to the main return: “Attach to Form 1040, 1040-SR, 1040-SS, or 1040-NR.” The instructions state the purpose: “Use Form 8888 if you want us to directly deposit your refund (or part of it) to either two or three accounts at a bank or other financial institution” in the United States. The form has places for three accounts, each with an amount, a routing number, an account type and an account number. A fourth line is marked “Reserved for future use”.
The accounts can be of several types:
| Account type | As the instructions list it |
|---|---|
| Traditional IRA, Roth IRA, SEP IRA | “A traditional individual retirement arrangement (IRA), Roth IRA, SEP IRA (but not a SIMPLE IRA)” |
| HSA | “A health savings account (HSA)” |
| Archer MSA | “An Archer MSA” |
| Coverdell ESA | “A Coverdell education savings account (ESA)” |
The total ties back to the return: “The total on line 5 must equal the total amount of the refund shown on your tax return.” “If the total on line 5 is different, your refund may be delayed.” The return itself is the 1040 family; senior filers will see the same attachment rule on the Form 1040-SR page.
Dollar examples at a glance
The only dollar amounts on the form and its instructions are small examples and one minimum.
| Item | As printed |
|---|---|
| Smallest deposit | “Each deposit must be at least $1.” |
| Math error raises a refund from $300 | “your refund is increased to $350” |
| Amount added to the last account | “The additional $50 will be added to the deposit to the account on line 3” |
| Corrected IRA contribution example | “You deduct $1,000 on your 2024 tax return for an IRA contribution.” |
Depositing a refund into an IRA
The IRA rule is specific: “You can have your refund (or part of it) directly deposited to a traditional IRA, Roth IRA, or SEP IRA, but not a SIMPLE IRA.” “You must establish the IRA at a bank or other eligible financial institution before you request direct deposit.”
The contribution year is the part that is easy to miss. The instructions say “You must also notify the trustee or custodian of your account of the year to which the deposit is to be applied (unless the trustee or custodian won’t accept a deposit for the prior year)” and add “If you don’t, the trustee or custodian can assume the deposit is for the year during which you are filing your return.”
Publication 590-A states the matching contribution rule. “You can make a contribution to your IRA by having your income tax refund (or a portion of your refund), if any, paid directly to your traditional IRA or Roth IRA.” “Contributions can be made to your traditional IRA for a year at any time during the year or by the due date for filing your return for that year, not including extensions.”
On designating the year, the publication says “If an amount is contributed to your traditional IRA between January 1 and April 15, you should tell the sponsor which year (the current year or the previous year) the contribution is for.” The annual limits are on the traditional IRA deduction limits page and the 2027 IRA contribution limit page.
Making sure the deposit counts for the right year
The instructions give a worked case using earlier years: “If you designate your deposit to be for 2023, you must verify that the deposit was actually made to the account by the due date of the return (not counting extensions).” “If the deposit isn’t made by that date, the deposit isn’t an IRA contribution for 2023.”
The consequence is an amended return: “you must file an amended 2023 return and reduce any IRA deduction and any retirement savings contributions credit you claimed.” Refund changes can also break an IRA deposit. The caution reads “you may need to correct your contribution or file an amended return.”
The instructions’ offset example carries numbers: “You deduct $1,000 on your 2024 tax return for an IRA contribution.” “You need to correct your contribution by contributing $1,000 to the IRA from another source by the due date of your return”. How the deposit is later reported by the custodian is on the Form 5498 boxes page.
What happens when the refund changes or a deposit is rejected
Math errors and offsets move the money between lines:
| Event | Instruction text |
|---|---|
| Refund increased by a math error | “the additional amount will be deposited to the last account listed” |
| Refund decreased by a math error | “the decrease will be taken first from any deposit to an account on line 3, next from the deposit to the account on line 2, and finally from the deposit to the account on line 1.” |
| Past-due federal tax offset | “the past-due amount will be deducted first from any deposit to an account on line 3” |
A rejected request does not necessarily stop the refund: “If your financial institution rejects one or two but not all of your direct deposit requests, the additional amount will be deposited to the last valid account listed.” Separately, the instructions say that if there are delays in processing the return, the entire refund will be deposited in the last valid account listed, and advise “Make sure the last account you list on Form 8888 is an account you would want the entire refund deposited in if this happens.”
Other offsets follow a different order: “the past-due amounts will be deducted first from the deposit to the account with the lowest routing number.”
Savings bonds and when the form cannot be used
The old savings bond option is gone. The instructions say “Purchase of savings bonds discontinued.” and explain “Form 8888 is now only used to split your direct deposit refund between two or more accounts.”
Several situations rule the form out. “You can’t have your refund deposited into more than one account if you file Form 8379, Injured Spouse Allocation.” For a single account, “If you want your refund deposited to only one account, don’t complete this form.” “Account must be in your name.”
The instructions also list rejection reasons, including “Three direct deposits of tax refunds have already been made to the same account or prepaid debit card.” and “Any numbers or letters on lines 1a through 3d are crossed out or whited out.”
The edition read for this page is Form 8888 (Rev. December 2025) and Publication 590-A for 2025, which are the revisions irs.gov served when they were read on 2026-10-16. Check the revision printed on the form you are filing, because Form 8888 is now a continuous-use form, converted from an annual revision, so the revision date may not change every year.
For the joint-return caution, the instructions say “If you file a joint return and complete Form 8888, your spouse may get at least part of the refund.” Related IRA reporting topics are on the Form 5329 page.
Common mistakes
- Splitting a refund into a SIMPLE IRA. The instructions allow traditional, Roth and SEP IRAs but say not a SIMPLE IRA.
- Skipping notice of the contribution year. The instructions say the trustee or custodian can assume the deposit is for the year during which the return is filed if no year is given.
- Listing a weak account last. The instructions say that when the bank rejects some deposit requests, or a math error increases the refund, the extra amount goes to the last account listed, so that account should be one that can take the money.
