Treasury Bills vs. Notes vs. Bonds: Key Differences Explained
When people talk about investing in the U.S. government, they usually mean one of three things: Treasury bills, Treasury notes, or Treasury bonds.
All three come from the U.S. Department of the Treasury. All three are considered safe investments. The big difference is time.
Treasury bills grow up fast and mature in one year or less.
Treasury notes take longer at two to ten years.
Treasury bonds are the patient ones maturing in twenty or thirty years.
Think of them like short naps versus long sleeps.
Choosing between them depends mostly on how long someone wants to wait. All three securities come with fixed interest rates and offer exemptions from state and local taxes.
All three can also be purchased directly through TreasuryDirect.gov without needing a broker. A common strategy investors use to manage interest-rate and reinvestment risk is laddering bonds to stagger maturities.
How T-Bills, T-Notes, and T-Bonds Pay You
Knowing the difference between a T-bill, a T-note, and a T-bond is a good start.
But understanding how each one actually pays is where things get interesting.
T-bills pay no regular interest.
Instead, investors buy them cheap and collect full face value at maturity.
T-notes and T-bonds both pay fixed interest every six months like clockwork.
T-bonds just keep those payments coming much longer since they mature in 20 or 30 years.
All three return face value at maturity.
Think of T-bills as a slow-building gift card and T-notes and T-bonds as steady paychecks over time.
Federal taxes apply, but states and local municipalities cannot touch the interest income earned from any of these securities.
Investors can purchase T-bills through TreasuryDirect or brokerage accounts, giving them flexible access depending on their preferred setup.
These securities are commonly used for capital preservation in conservative portfolios.
What Rising Rates Do to Treasury Prices Before Maturity
Picture a seesaw on a playground. When one side goes up, the other goes down.
Think of Treasury prices and interest rates as a seesaw — when one rises, the other must fall.
Treasury prices and interest rates work exactly the same way. When rates rise, existing Treasury prices fall. Why? Because newer Treasuries offer better yields, making older ones less attractive. Investors pay less for those older securities until the yields match up.
Longer-term Treasuries like T-bonds feel this drop more sharply than short-term T-bills. A one-point rate increase can knock a 10-year Treasury’s price down nearly nine percent. This sensitivity is tied to duration, which measures how much a bond’s price will change in response to interest rate movements.
Holding until maturity avoids locking in those losses, but selling early could mean taking a real hit. Treasury bills held to maturity always return face value, regardless of what interest rates do in the meantime.
Monetary policy changes, such as central bank rate hikes, often drive these shifts in yields and prices, especially in Treasury markets.
Federal and State Tax Treatment for Treasury Investors
Taxes show up whether investors want them to or not, but Treasury securities come with a helpful split in how they get taxed.
The federal government does tax Treasury interest as regular income. No escaping that part. Stop-loss orders can help manage downside risk in taxable brokerage accounts.
However, states and cities cannot touch it. Treasury interest stays completely off the table for state and local taxes.
That exemption gets especially valuable for people living in high-tax states.
T-bills report interest once at maturity while notes and bonds report it each semiannual payment.
Either way the pattern stays the same: federal taxes yes, state taxes no. High earners should note that Treasury interest can trigger the 3.8% Net Investment Income Tax on top of their regular marginal rate. Investors receiving taxable Treasury interest may need to account for estimated tax payments on that additional income throughout the year.
Which Treasury Security Fits Your Time Horizon and Income Needs?
Choosing the right Treasury security comes down to two simple questions: when is the money needed, and does regular income matter along the way? Matching answers to the right security makes investing simpler.
Picking the right Treasury security starts with two questions: when is the money needed, and does income matter?
- Under one year: T-bills park money safely until it’s needed soon. Index fund performance shows how low-cost, benchmark-matching choices can matter for long-term returns.
- Two to ten years: Treasury notes pay income twice yearly while holding value.
- Twenty to thirty years: Treasury bonds suit long-term goals needing steady income.
- Income priority: Notes and bonds beat bills for regular cash flow.
Matching maturity to goals keeps surprises small and plans on track. Treasury securities are also exempt from state and local taxes, making them more tax-efficient than many other fixed-income investments. All Treasury securities carry the full faith and credit of the U.S. government, meaning they are backed by the government’s commitment to repay its debt obligations.
