I bond tax tips: defer, exclude, and split

By BondValue Editorial · 2026-02-14

In short: I bond interest is exempt from state and local tax and you can defer the federal tax until you cash the bond. You can also make the interest fully tax-free if used for qualified higher education, or elect to report interest annually to spread the tax — useful for kids' bonds.

Savings bonds have some of the friendliest tax treatment in personal finance. Here’s how to make the most of it. (This is general information, not tax advice — see a professional and the taxes page.)

Three useful moves

  1. Defer until you choose. The default is that you owe no federal tax until you redeem. That lets you time redemptions to a low-income year (retirement, a gap year, a low-earning year) when your bracket is lower.
  2. Use the education exclusion. Under the Education Savings Bond Program, interest is fully tax-free if you cash the bonds in the same year you pay qualified higher-education expenses, subject to income phase-outs and the rule that the bond owner was 24+ at issue. Claimed on IRS Form 8815.
  3. Elect annual reporting for kids’ bonds. For a child with little income, electing to report interest annually can make it fall under the child’s standard deduction — potentially tax-free as it accrues. The election is all-or-nothing across your bonds, so weigh it carefully.

Don’t forget maturity

At 30 years the bond stops earning and the interest becomes taxable that year even if you don’t cash it. Track your oldest bonds and redeem matured ones. Estimate accrued interest with the value calculator.

Frequently asked questions

Do I have to pay taxes on I bonds every year?

No. By default, all the interest is taxed (federally) only in the year you cash the bond or it matures at 30 years. Alternatively you can elect to report interest annually — once chosen, that election applies to all your savings bonds.

How can I avoid taxes on I bonds?

You can't avoid federal tax entirely, but you can defer it until redemption, and you can exclude it completely if you use the proceeds for qualified higher-education expenses (subject to income limits, via IRS Form 8815). Savings bonds are always exempt from state and local income tax.

Is I bond interest taxed if I never cash the bond?

Yes — at 30-year final maturity the bond stops earning and all accrued interest becomes federally taxable that year, whether or not you cash it. Don't forget to report it (and to redeem the matured bond).
