You can buy I Bonds with your tax refund by directing the IRS to send part or all of it to TreasuryDirect, the federal savings bond platform

When you file your federal tax return, you have the option to split your refund across multiple accounts. Instead of depositing the entire amount to your bank, you can instruct the IRS to send a portion directly to TreasuryDirect in the form of I Bonds. This happens during the tax filing process itself — you do not buy the bonds after receiving the refund.

The process requires you to set up a TreasuryDirect account before you file your return, because the IRS needs your account information to send the money there. Once your account exists, you enter the routing and account details on your tax form, and the IRS handles the transfer when your refund is processed.

Key Takeaways

  • You must open a TreasuryDirect account before filing your tax return, because the IRS needs your account number to direct the refund there.
  • I Bonds purchased with a tax refund are issued in your name only — you cannot buy them in joint names or for someone else this way.
  • The IRS sends the refund to TreasuryDirect in the form of a paper bond certificate mailed to your address, not as an electronic purchase.
  • You can split your refund between a bank account and TreasuryDirect, but the minimum amount sent to TreasuryDirect is $25.
  • The bond's issue date is the date the IRS processes your refund, not the date you file or the date you set up your account.

Setting up your TreasuryDirect account before filing

Go to treasurydirect.gov and create an account using your Social Security number, email address, and a password. You will need to verify your identity through a third-party service — the site will ask for your driver's license number or state ID number and your date of birth. This verification is when ready.

Once your account is open, log in and note your account number. This is the number you will enter on your tax return. Write it down or take a screenshot, because you will need it when you fill out the refund routing section of your tax form.

If you file through a tax software like TurboTax, H&R Block, or TaxAct, the software will ask whether you want to split your refund. If you file on paper using Form 1040, you will use Schedule 3 to direct part of your refund to TreasuryDirect. If you use a tax preparer, tell them you want to buy I Bonds with part of your refund and give them your TreasuryDirect account number.

How the refund becomes a bond

When you direct your refund to TreasuryDirect, the IRS does not buy individual bonds for you. Instead, it sends the money to your TreasuryDirect account, and the system automatically purchases I Bonds in your name. The bonds are issued as paper certificates and mailed to the address on file with the IRS.

The issue date of the bond is the date the IRS processes your refund, not the date you file your return or the date the certificate arrives in the mail. This matters because I Bond interest rates change every six months, on May 1 and November 1. If your refund processes on April 28, your bond will earn the rate in effect from May 1 forward, even though you have not yet received the physical certificate.

You will receive a paper bond certificate in the mail within a few weeks. Keep it in a safe place — you will need it if you ever want to redeem the bond. You can also view your bonds and their current value anytime by logging into your TreasuryDirect account online.

Limits on how much you can direct to I Bonds

There is no upper limit on how much of your refund you can send to TreasuryDirect for I Bonds. However, the IRS has an annual purchase limit: you can buy a maximum of $10,000 in I Bonds per calendar year using your own money, and an additional $5,000 using your tax refund. This means if you have already bought $10,000 in I Bonds earlier in the year through TreasuryDirect, you can still direct up to $5,000 of your refund to bonds.

The minimum amount you can direct to TreasuryDirect is $25. If your refund is smaller than that, you cannot split it — you must send the entire amount to your bank account.

If you are married and file jointly, each spouse has their own $10,000 annual limit plus a separate $5,000 refund limit. You can split the joint refund between two TreasuryDirect accounts, one for each spouse, as long as each account receives at least $25.

What happens if you change your mind after filing

Once you file your return with the refund directed to TreasuryDirect, you cannot change that instruction. The IRS will process the refund as you directed it. If you realize you made a mistake or changed your mind, you have two options: wait for the bond certificate to arrive and then sell it back to the government through TreasuryDirect, or contact the IRS to see if you can amend your return before the refund is processed.

Amending your return is only possible if you file before the IRS processes your refund. Once the refund has been sent to TreasuryDirect, it is too late. Selling the bond back is straightforward — you log into TreasuryDirect, request a redemption, and the money is deposited to your bank account within a few business days. However, I Bonds have a one-year holding period: you cannot redeem them until at least one year after the issue date. If you redeem before five years have passed, you lose the last three months of interest.

Tax implications of I Bonds bought with a refund

I Bonds earn interest, and that interest is subject to federal income tax. You do not pay tax when you buy the bond or when it is issued — you pay tax on the interest when you redeem the bond or when it reaches final maturity (30 years). You can choose to report the interest each year as it accrues, or wait until you cash in the bond.

If you use the bond to pay for education expenses, you may be able to exclude the interest from your taxable income under the Education Savings Bond Program. This requires meeting specific conditions: the bond must be issued in your name (not your child's), you must be at least 24 years old when the bond is issued, and the proceeds must be used for tuition and fees at an accredited school. The exclusion phases out at higher income levels.

Buying I Bonds with your tax refund does not change how much tax you owe or how much your refund is. The refund amount is the same whether it goes to your bank or to TreasuryDirect — you are straightforward choosing where the money goes.

Frequently Asked Questions

Can I buy I Bonds in my child's name with my tax refund?

No. I Bonds purchased through a tax refund must be issued in your name only. If you want to buy bonds for your child, you must purchase them separately through TreasuryDirect using your own money, and they will be registered in your child's name with you listed as the owner.

What if my TreasuryDirect account gets hacked or I lose access before my refund arrives?

Contact TreasuryDirect when ready at 844-284-2676. They can help you regain access or work with the IRS to redirect the refund if it has not yet been processed. If the refund has already been sent to the account, the bonds are in your name and you can recover them by proving your identity to TreasuryDirect.

Do I Bonds bought with a tax refund earn interest differently than bonds I buy with my own money?

No. The interest rate is the same regardless of how you purchased the bond. The only difference is the annual purchase limit: you can direct up to $5,000 of a refund to bonds, separate from the $10,000 limit on direct purchases.

How long does it take for the bond certificate to arrive in the mail?

Paper bond certificates typically arrive within two to four weeks after the IRS processes your refund. Your bond starts earning interest on the issue date (the date the IRS processed the refund), not the date you receive the certificate, so you are not losing any interest while you wait for it to arrive.

Can I direct my refund to TreasuryDirect if I owe back taxes or child support?

No. If you owe federal taxes, the IRS will intercept your refund to pay what you owe. If you owe child support or other debts, state agencies can also intercept your refund. You cannot direct a refund to TreasuryDirect if it is subject to offset.
