How Do Series I Savings Bonds Work?

illustration showing how fixed rate and inflation rate equal i bonds composite rate

The Dual-Rate Structure

If I Bonds have every confused you, that's normal. Unlike other investments, Series I Bonds have two rates:

  1. Fixed Rate: Set at the time of purchase and remains unchanged for the life of the bond.
  2. Inflation Rate: Adjusts every six months based on changes in the CPI-U.

Current I Bond Rates (February 2025)

Fixed Rate: 1.20% (Locked for 30 years)
Inflation Rate: 1.90% (Adjusts semi-annually)
Composite Rate: 3.11% (Through April 2025)
Highest since 2007

The Hidden Significance:
That 1.20% fixed rate isn't just a number. It's the highest we've seen since 2007.
For perspective, my clients who locked in the 3.60% fixed rate in 2000 have seen their bonds outperform most "safe" investments for over two decades.

Compounding Interest

  • Interest on I Bonds accrues monthly and compounds semiannually.
  • This means every six months, your interest earns interest, accelerating your savings growth.

US I Bonds Tax Implications and Strategic Uses

Graphic explaining the tax advantages of I Bonds

The federal tax treatment of I Bonds offers unique advantages that require strategic planning:

Federal Tax Benefits - Strategic Timing for Redemption

  • Deferred Taxes: You won't pay federal income tax on the interest until you redeem the bonds or they mature after 30 years.
  • Education Tax Exclusion: Use I Bonds for qualified higher education expenses and you might exclude the interest from federal taxes altogether, subject to income limits.
"Saving for college? I Bonds could be your financial ace in the hole, offering tax-free growth when used for education."

Tax Deferral Options:
1. Annual Reporting: Optional, rarely optimal
2. Deferred Reporting: Until redemption/maturity
3. Final Maturity: Year 30 mandatory reporting

Calculation Example:
Original Purchase: $10,000
Accrued Interest: $3,000
Taxable Amount: $3,000 (interest only)

State and Local Tax Exemptions: Maximizing Your Advantage

Interest earned is exempt from state and local taxes, making I Bonds an attractive option if you live in a high-tax state like California or New York.

Tax Exemption Matrix:
State Income Tax: 100% exempt
Local Income Tax: 100% exempt
Alternative Minimum Tax: Not counted
Net Investment Income Tax: Excluded

"Choosing between I Bonds and EE Bonds is like deciding between a variable and fixed-rate mortgage; it all depends on your outlook and risk tolerance."

Early Redemption Penalties

  • Both have a minimum holding period of 12 months.
  • Did you redeem your bond before 5 years? Lose the last 3 months of interest on both.

Decision Point: If you're worried about inflation eroding your savings, I Bonds offer that protective shield. If you prefer a guaranteed return, EE Bonds might be your pick.

How to Buy Series I Savings Bonds

"Buying I Bonds is as easy as online shopping, but instead of a package on your doorstep, you get a boost in your financial security."

Option 1: TreasuryDirect.gov

  1. Open an Account: Visit TreasuryDirect.gov and set up a free account.
  2. Purchase Bonds: Buy electronic I Bonds in any amount from $25 up to $10,000.

Option 2: Tax Refund

  • Buy Paper Bonds: Use IRS Form 8888 when filing your tax return to allocate up to $5,000 of your refund to purchase paper I Bonds.

Maximizing Returns with Strategic Timing

Michael Ryan Money Pro Tip:

Consider purchasing I Bonds late in the month because the issue date is the first of the month in which you buy them. This effectively gives you up to a month's additional interest.

The semi-annual rate adjustment cycle for Series I Savings Bonds follows a precise calendar that savvy investors can leverage for maximum returns. Understanding these windows is crucial for optimal timing.

Understanding the 6-Month Rate Lock Cycle:

Each I Bond purchase initiates a precise rate lock sequence:

  • Months 1-6: Fixed rate guaranteed (initial rate period).
  • Months 7-12: Second rate period applied.
  • Months 13+: Semi-annual adjustments based on inflation.

Why April and October Matter for I Bond Investors
The Treasury announces new rates every six months, effective May 1 and November 1. However, the real opportunity lies in the last few business days of April and October. Here's why:

Factors to Consider Before Investing

"I Bonds are like a financial Swiss Army knife—they offer safety, inflation protection, and tax benefits all in one tool."

  • Immediate Liquidity Needs: Not ideal, as you can't touch the funds for 12 months.
  • Short-Term Goals (<5 years): Be cautious due to the 3-month interest penalty.
  • If inflation is expected to rise, I Bonds become more attractive.
  • Compare the I Bond composite rate to other low-risk options like Certificates of Deposit (CDs) or Treasury Inflation-Protected Securities (TIPS).

Are I Bonds a Good Investment in 2025?

Yes, I Bonds can be a solid investment option. Particularly for risk-averse investors seeking inflation protection and guaranteed returns. This fixed rate ensures your investment will grow above inflation over the bond's 30-year life, making I Bonds an attractive long-term savings tool.

Can I Lose Money on I Bonds?

No, I Bonds are one of the safest investments available. As they are backed by the full faith and credit of the U.S. government. Your principal is guaranteed not to decline, even during periods of deflation. The only "loss" occurs if you redeem the bond within five years, as you forfeit the last three months of interest.

What Happens After 30 Years?

After 30 years, I Bonds stop earning interest. At that point, it’s time to redeem them because keeping them beyond maturity offers no additional financial benefit. Federal taxes on accrued interest are due upon redemption, so plan accordingly to minimize any tax impact.

How is the bond redeemed at maturity?

At maturity, an I Bond is redeemed by cashing it in through TreasuryDirect or a financial institution Receiving the principal plus all accrued interest, with federal taxes due on the composite interest earned.

How Do I Bonds Compare to Other Investments?

While I Bonds offer unmatched safety and inflation protection, their composite rate is less competitive than high-yield savings accounts (4-5%) or Treasury bills (4-5%) in today’s market. However:

High-yield accounts lack inflation adjustments. And Treasury bills don’t offer the same tax advantages or long-term compounding benefits. For long-term savers or those prioritizing inflation hedging over yield maximization, I Bonds remain an excellent choice.

If you're seeking a low-risk investment that keeps pace with inflation and offers tax advantages, Series I Savings Bonds are worth considering.
