Treasury Bills Explained: A Simple Starting Point for Beginners
Treasury bills can look confusing at first. A quote may show a discount rate, an investment yield, a purchase price and a maturity date, leaving you to figure out which number actually represents your return. The underlying idea is much easier to follow: Treasury bills are short-term U.S. government debt securities that are generally purchased for less than their face value and paid at face value when they mature.
That setup can make T-bills useful for money with a known time horizon. You choose a maturity, purchase the bill, and receive its scheduled face value at maturity if you hold it until then. Your actual investment return comes from the difference between what you paid and what you receive, while taxes and the timing of your investment also affect the result. This is one reason T-bills should not be judged by a quoted rate alone.
The key idea: a T-bill’s purchase price, face value and time to maturity work together to determine its return. Terms such as discount rate and yield describe that return in different ways, so they should not be treated as identical.
There is also a practical side to the decision. Treasury bills are not savings accounts, money market accounts or CDs, even though investors sometimes use them for similar short-term goals. T-bills are U.S. government securities, while bank and credit union deposit products follow different rules for access, insurance, interest payments and withdrawals. Your choice can therefore change depending on how soon you may need the money and how much flexibility you want.
This guide starts with the basics and gradually moves into the details that matter for an actual purchase. We will cover T-bill terms, auctions, pricing, yields, maturity, taxes, safety, buying options and early-sale considerations. You will also see how T-bills compare with CDs, high-yield savings accounts and money market accounts. If you are specifically weighing a CD against a Treasury bill, our CD vs. Treasury bills guide gives that comparison a closer look.
What You’ll Learn
- What Treasury bills are and how they differ from other Treasury securities and bank deposit products.
- How T-bills work from purchase and auction through maturity and payment.
- How Treasury bill rates and yields work and why the purchase price matters when measuring your return.
- How to buy Treasury bills through TreasuryDirect or a brokerage account, including the practical differences between the two.
- How Treasury bill taxes work, including federal income tax and the treatment of Treasury interest for state and local taxes.
- What to consider before choosing a maturity, including cash needs, reinvestment and the possibility of selling before maturity.
- How T-bills compare with other short-term options so you can see where they may fit alongside savings accounts, money market accounts and CDs.
Treasury Bills: Quick Answer & Key Takeaways
Quick answer: What are Treasury bills?
Treasury bills, usually called T-bills, are short-term U.S. government securities with maturities of one year or less. They are generally issued at a price below their face value and pay the face value when they mature. Because there is normally no periodic interest payment, the difference between the purchase price and the amount paid at maturity represents the bill’s basic return before taxes. Investors can generally buy T-bills through TreasuryDirect or a brokerage account.
T-bills can suit money that has a defined short-term purpose, such as cash you expect to use at a known point in the future. Their structure is different from a savings account, money market account or CD. T-bills are securities rather than bank deposits, so they are not covered by FDIC deposit insurance. If you hold one until maturity, you receive its scheduled face value; if you sell it before maturity, its market price may be higher or lower than what you originally paid.
Key Takeaways
- Short-term by design: Treasury bills have maturities of one year or less, with several standard terms available.
- Usually bought below face value: Instead of making regular coupon payments, a T-bill generally provides its return through the difference between its purchase price and face value at maturity.
- Rate and yield are not the same thing: A quoted discount rate and an investment yield use different calculations, so the two figures should not be treated as interchangeable.
- Two common ways to buy: TreasuryDirect and brokerage accounts can both provide access to Treasury bills, although the purchasing experience and available features can differ.
- Federal tax applies: Treasury bill interest is generally subject to federal income tax but is exempt from state and local income taxes.
- Early selling is different from holding to maturity: A T-bill sold before maturity is traded at its current market price, which can be above or below the original purchase price.
- Convenience still matters: T-bills can work well for planned short-term cash needs, while a savings account, money market account or CD may be a better fit when immediate access or a different account structure matters more.
Bottom line: To understand a Treasury bill, start with four questions: How much do I pay? What will I receive at maturity? When will I receive it? And how will the return be taxed? Once those pieces are clear, comparing T-bills with other short-term options becomes much easier.
T-Bills at a Glance: Quick Facts, Best For & Key Numbers
Before getting into auctions, pricing and yield calculations, it helps to see the basic structure in one place. Treasury bills are built for short-term borrowing by the U.S. government, so the details that matter most are the bill’s maturity, purchase price, face value, yield and how you plan to use the money.
| Quick Fact | What It Means |
|---|
| Investment type | Short-term U.S. government debt security |
| Maturity | One year or less; common terms include 4, 8, 13, 17, 26 and 52 weeks |
| Purchase price | Generally below the bill’s face value |
| How returns are paid | T-bills generally do not make periodic coupon payments; the return is reflected in the price paid and the face value received at maturity |
| Denomination | Generally available in $100 face-value increments |
| Where to buy | TreasuryDirect and many brokerage accounts |
| Federal tax | Treasury bill interest is generally subject to federal income tax |
| State & local tax | Interest is generally exempt from state and local income taxes |
| FDIC insurance | Not FDIC-insured because T-bills are securities rather than bank deposits |
Who Are T-Bills Best For?
T-bills may fit investors who have a defined short-term goal and can leave the money invested until a chosen maturity date. Examples include cash set aside for a planned purchase, an upcoming expense, or a temporary place to hold funds before making another investment. They can also be used as one part of a short-term Treasury strategy, including a ladder with several maturity dates.
The tax treatment can make T-bills particularly interesting for investors who live in a state or locality that imposes income tax. Treasury interest is generally subject to federal income tax but exempt from state and local income taxes. The value of that exemption depends on your tax situation and should be considered alongside the yield available when you invest.
Look beyond the headline rate
A T-bill quote contains more than one useful number. Pay attention to the investment yield, purchase price, maturity date, tax treatment and what you expect to do with the money afterward. These details become especially useful when comparing T-bills with CDs or money market accounts.
Complete Beginner Guide: What Are Treasury Bills?
Treasury bills, commonly called T-bills, are short-term debt securities issued by the U.S. Department of the Treasury. In simple terms, you are lending money to the U.S. government for a defined period. The Treasury issues the bill with a stated face value and pays that face value when the bill matures, subject to the terms of the security.
What makes T-bills different from many traditional bonds is the way the return is structured. Treasury bills generally do not make periodic coupon payments. Instead, newly issued bills are sold at a discount to their face value, so the amount you pay is generally less than the amount you receive at maturity. That difference is the basic return on the original investment before taxes.
Think of a T-bill this way
Buy a newly issued T-bill for less than its face value → hold it until maturity → receive the face value. The difference between those amounts is the basic return before taxes. The actual purchase price depends on the bill’s auction price.
Treasury Bills Are One Part of the Treasury Family
Treasury bills are one type of marketable Treasury security. The easiest way for a beginner to distinguish them from Treasury notes and bonds is to look at the maturity and payment structure. Bills are short-term securities with maturities of one year or less. Treasury notes generally have intermediate maturities and pay interest every six months. Treasury bonds are longer-term securities and also generally pay interest every six months.
| Security | Maturity | Basic Payment Structure |
|---|
| Treasury bills | One year or less | Generally issued below face value and paid at face value at maturity |
| Treasury notes | More than one year to 10 years | Generally pays interest every six months |
| Treasury bonds | More than 10 years | Generally pays interest every six months |
What Does a T-Bill Maturity Mean?
The maturity date is the date on which the Treasury bill reaches the end of its stated term. Common Treasury bill terms include short periods such as 4, 8 and 13 weeks, along with longer bill terms such as 17, 26 and 52 weeks. The exact maturities available can vary with Treasury issuance schedules, so investors should check the current offering before placing an order.
Maturity is more than a number on an investment screen. It tells you when the bill is scheduled to reach its end date and helps you decide whether the timing fits your cash needs. A shorter bill may suit money you expect to use relatively soon, while a longer bill may make sense when you can leave the funds invested for a longer period. 4-Week Treasury Bills Explained
How Much Can You Invest?
Treasury bills are generally issued in $100 and additional $100 multiples of face value. Your actual purchase amount for a newly issued bill can be lower than its face value because the bill is sold at a discount. The price you pay depends on the terms and pricing of the specific Treasury bill you purchase.
A simple illustration
Imagine a newly issued Treasury bill with a $1,000 face value and an illustrative purchase price of $980. If you hold that bill until maturity and receive $1,000, the $20 difference represents the basic return before taxes. This is only an example—the actual price and return depend on the specific Treasury bill and its market conditions.
What Treasury Bills Are Not
- Not a savings account: A T-bill is a marketable government security, not a bank deposit.
- Not FDIC-insured: FDIC deposit insurance applies to eligible deposits at FDIC-insured banks, not Treasury securities.
- Not a traditional coupon bond: T-bills generally do not send periodic interest payments during their term.
- Not automatically the right choice for every cash goal: The maturity, access requirements, taxes and available yield all matter when deciding where short-term money belongs.
The beginner takeaway: A Treasury bill is a short-term U.S. government security with a defined maturity. For a newly issued bill, you generally pay less than its face value and receive the face value when it matures. The next step is learning how the auction, purchase price, discount rate and investment yield fit together.
How Treasury Bills Work: Purchase, Discount, Yield & Maturity
The easiest way to understand a newly issued Treasury bill is to follow it from the auction to maturity. You select a bill with a particular term, place an order, and the auction determines the price and yield for the securities sold. Because T-bills generally do not make periodic coupon payments, the return is built into the difference between the price paid and the face value received at maturity. What Are Treasury Bills? Complete Beginner Guide
Step 1
Choose a bill
Select a maturity that matches the period you expect to leave the money invested.
Step 2
Place your order
Use TreasuryDirect or a brokerage account to submit your purchase.
Step 3
Auction sets the price
For a new issue, the auction establishes the applicable price and yield.
Step 4
Hold or sell
Hold to maturity for the face value or sell earlier through the secondary market.
1. Start With the Treasury Auction
Newly issued Treasury bills are sold through auctions. An individual investor can generally place a noncompetitive bid, which means the investor agrees to accept the yield determined at the auction. You specify the amount of securities you want to buy rather than naming the yield you require. TreasuryDirect vs Brokerage: Which Is Better for T-Bills?
A competitive bid works differently because the bidder specifies the discount rate they are willing to accept. The Treasury accepts bids according to the auction rules until the amount offered for sale is allocated. For a beginner using a noncompetitive order, the important point is simple: you are not trying to guess the winning auction yield yourself. How Do Treasury Bills Work?
T-bill yield vs. interest rate
2. Your T-Bill Is Priced Below Face Value
Newly issued Treasury bills are generally sold at a discount to face value. Suppose, purely as an illustration, that you purchase a bill with a $10,000 face value for $9,800. If you hold that bill until maturity and receive $10,000, the $200 difference is the basic return before taxes. Treasury Bill Discount Rate Explained
Why you should not call that simply “2% interest”
The $200 difference is 2% of the $10,000 face value, but it is not automatically a 2% annual yield. The annualized investment yield depends on the purchase price and the length of time until maturity. This is why two T-bills with different maturities cannot be compared by looking only at the dollar discount.
3. Discount Rate, Price and Investment Yield Tell Different Stories
Treasury auction results can show a discount rate, a price and an investment rate. The discount rate measures the bill’s discount from face value using a 360-day basis. The investment rate, commonly described as the bond-equivalent yield, annualizes the return using a different convention. As a result, the discount rate and investment rate are related but are not interchangeable. Treasury Bills vs Treasury Bonds: What’s the Difference?
The four numbers worth watching
Face value
The amount paid when the bill reaches maturity.
Discount rate
A Treasury auction measure based on the bill’s discount.
Investment rate
An annualized return measure useful for comparing investments.
4. What Happens When the T-Bill Matures?
If you hold a Treasury bill until maturity, the Treasury pays its face value. At that point, you can use the proceeds for the purpose you originally had in mind, move the money to another account or investment, or reinvest in another Treasury bill if an eligible reinvestment option is available.How Do Treasury Bills Make Money?
Selling before maturity is different. T-bills can be traded in the secondary market, generally through a brokerage. Their market prices can move as interest rates, demand and other market conditions change. As a result, an early sale may produce more or less than your original purchase price, and you should not assume that you will receive the bill’s full face value before its maturity date. What Happens If You Hold a Treasury Bill Until Maturity?
The practical rule: For a newly issued T-bill, look at the purchase price, face value, investment rate and maturity date. If there is a chance you will need the money early, also consider how the bill could be priced in the secondary market instead of relying on its maturity value.What Happens When a Treasury Bill Matures?
Benefits & Drawbacks of T-Bills
Treasury bills are often attractive because they combine a short maturity with the credit backing of the U.S. government. But a strong credit profile does not make every T-bill equally useful for every cash need. Your decision also depends on how long you can leave the money invested, how you plan to access it, what happens when the bill matures and how taxes affect the return. How Treasury Bill Auctions Work. Treasury Bill Auction Dates Explained
Benefits of Treasury Bills
- Low credit risk: T-bills are direct obligations of the U.S. government, so credit risk is generally considered very low compared with many other investments.
- Short, defined maturities: Treasury bills have terms of one year or less, giving investors several ways to match an investment with a known cash timeline.
- Known maturity value: If you hold a newly issued T-bill until maturity, the Treasury pays its stated face value.
- State and local tax advantage: Interest from U.S. Treasury securities is generally exempt from state and local income taxes, although federal income tax generally applies.
- Accessible through common investment platforms: Investors can generally purchase newly issued T-bills through TreasuryDirect or through many brokerage accounts.
Drawbacks to Consider
- Not designed for everyday spending: A T-bill is a security rather than a checking or savings account, so it does not provide ordinary deposit-account transaction features.
- Early selling can change the result: If you sell before maturity, the bill’s market price may be higher or lower than the amount you originally paid.
- Reinvestment risk: When a T-bill matures, a new bill may carry a different yield. You cannot assume that the rate on your current bill will still be available for the next investment.
- Inflation can reduce real returns: Earning a positive nominal return does not guarantee that your money will gain purchasing power after inflation.
- No FDIC deposit insurance: T-bills are Treasury securities, not deposits at an FDIC-insured bank.
Where the Trade-Offs Matter Most
The biggest advantage of a T-bill can be its defined timeline. If you know that a portion of your cash can remain invested for several weeks or months, you can choose a maturity that lines up with that goal. That is different from keeping the same money in an account designed for frequent deposits, withdrawals and everyday access.
The trade-off becomes more noticeable if your plans change. You can potentially sell a T-bill before maturity through the secondary market, but the selling price is determined by market conditions at that time. A short-term security can therefore still have price risk if you need to exit before its maturity date.
Taxes can also influence the comparison. For an investor who pays state or local income tax, the exemption for Treasury interest can make a T-bill’s after-tax return more attractive than the headline yield of a taxable alternative. The actual advantage varies by tax bracket, location and the competing investment’s yield.
Bottom line: T-bills are most compelling when short maturity, low credit risk and favorable Treasury tax treatment fit the job your money needs to do. Their limitations become more relevant when you need everyday access, may have to sell early, or want to keep the money invested for a much longer period.
Treasury Bills Comparison Table: T-Bills vs. Savings, MMAs & CDs
A Treasury bill may look attractive because of its yield, but the yield is only one part of the decision. Savings accounts, high-yield savings accounts, money market accounts and CDs solve somewhat different problems. The comparison below focuses on the features that can change the real-world outcome: access to your money, term, rate structure, insurance and tax treatment.
| Feature | Treasury Bills | High-Yield Savings | Money Market Account | CD |
|---|
| What it is | U.S. government security | Bank deposit account | Bank deposit account | Bank deposit account |
| Time structure | One year or less | No fixed maturity | No fixed maturity | Fixed term selected at opening |
| How return is earned | Generally bought below face value and paid at face value at maturity | Interest credited according to the account terms | Interest credited according to the account terms | Interest paid or credited according to the CD terms |
| Rate structure | Determined by auction for new issues; market pricing applies to secondary-market trades | Usually variable | Usually variable | Generally fixed for the selected term |
| Access to money | Not designed for everyday spending; early access generally means selling before maturity | Generally accessible, subject to account terms | Access features vary by institution | Generally limited before maturity; early-withdrawal rules may apply |
| FDIC insurance | No | Generally yes, at an FDIC-insured bank within applicable limits | Generally yes, at an FDIC-insured bank within applicable limits | Generally yes, at an FDIC-insured bank within applicable limits |
| State & local income tax | Generally exempt | Generally subject to applicable state and local income taxes | Generally subject to applicable state and local income taxes | Generally subject to applicable state and local income taxes |
| Often fits | Defined short-term goals | Accessible cash that can earn interest | Cash with certain deposit-account features | Money that can remain invested for a set term |
T-Bills vs. High-Yield Savings Accounts
A high-yield savings account is built around access. You can generally keep adding money, withdraw funds according to the account terms and earn a variable interest rate. A T-bill works differently because it has a defined maturity and is a security rather than a deposit account. If the money may be needed unexpectedly, the flexibility of a savings account can be more valuable than a modest difference in yield.
Treasury Bills vs High-Yield Savings Accounts
T-Bills vs. Money Market Accounts
A money market account is a bank deposit account, while a Treasury bill is a government security. An MMA may offer features such as checks or a debit card, but those features vary by institution and account. T-bills are not designed for everyday transactions. If your priority is keeping cash available while earning interest, an MMA may be more convenient; if you have a defined investment period, a T-bill may be worth comparing.Treasury Bills vs Money Market Accounts
For a deeper look at this specific choice, see our .Treasury Bills vs Money Market Accounts: Which Is Safer?
T-Bills vs. CDs
CDs and T-bills can both work for money that does not need to remain fully accessible. A CD is a bank deposit with a fixed term and institution-specific early-withdrawal rules. A newly issued T-bill is priced at auction and generally pays its face value at maturity. T-bills and CDs also have different insurance and tax structures, so comparing their advertised yields without considering those differences can give you an incomplete picture.Treasury Bills vs CDs: Which Is Better in 2026?
If a CD is your main alternative, our Treasury Bills vs CDs: Tax Differences provides a more focused comparison.
How to compare them: Start with more than the advertised yield. Look at the after-tax return, access to your money, time commitment, insurance coverage and what happens if your plans change. A slightly lower yield can be worthwhile if it gives you the flexibility or protection your situation requires.
Treasury Bills: Costs, Taxes, Risks & Expert Tips
Treasury bills have a straightforward structure, but there are still a few details worth checking before you buy. The purchase method, federal tax treatment, state-tax advantage, maturity date and what happens if you need the money early can all affect your actual result. Looking at the yield alone can leave out some of the most useful information.
What Does It Cost to Buy Treasury Bills?
TreasuryDirect says it does not charge a purchase fee or commission when you buy Treasury securities directly through the platform. You still pay the purchase price of the security. If you use a brokerage instead, review that firm’s pricing and account terms because the overall cost structure can differ by provider.Who Should Buy Treasury Bills?
Cost tip: With a newly issued T-bill held to maturity, the important comparison is not just whether there is a transaction fee. Think about the amount of cash committed, the maturity date and the return you could have earned elsewhere during the same period.
How Are Treasury Bills Taxed?
Interest income from Treasury bills is subject to federal income tax but is exempt from state and local income taxes. For Treasury bills issued at a discount, the difference between the discounted purchase price and the face value received at maturity is generally treated as interest income. The IRS says this income is generally reported when the bill is paid at maturity.
Treasury interest is generally reported on Form 1099-INT, with U.S. Treasury obligations reported in Box 3. Keep your purchase and maturity records with your tax documents so you can reconcile the information reported to you.Are Treasury Bills Exempt From State Taxes?
Illustrative tax example
Suppose an illustrative T-bill has a $10,000 face value and you pay $9,800 for it. If you hold it until maturity and receive $10,000, the $200 difference represents the bill’s return before federal taxes. The Treasury interest is generally subject to federal income tax but exempt from state and local income taxes.
Four Risks to Keep in Mind
1. Early-sale risk
If you sell before maturity, the market price may be different from the price you originally paid. Your realized return can therefore be higher or lower than the result you expected from holding the bill to maturity.sell a T-bill before maturity
2. Reinvestment risk
When a T-bill matures, the yield available on a new bill may be higher or lower than the yield on your previous investment.
3. Inflation risk
A T-bill can produce a positive nominal return while your purchasing power grows more slowly after accounting for inflation.
4. Timing risk
Choosing a maturity that does not line up with your cash need can force you to reconsider your plans or potentially sell before maturity.
Expert Tips for Buying T-Bills
- Match the maturity to the goal.
If you expect to need the money on a particular date, choose a maturity that fits that timeline instead of focusing only on the highest available yield. - Compare the right rate measure.
Treasury auctions can quote discount rates and investment rates using different conventions. Do not assume two differently labeled percentages are directly interchangeable. - Account for taxes.
Federal income tax still applies, but the exemption from state and local income taxes can make Treasury bills particularly interesting for investors who live in jurisdictions with income taxes. - Keep emergency cash separate.
A T-bill can work well for a planned short-term goal, but money reserved for an unexpected expense may be better kept in an account designed for easier access. - Have a maturity plan.
Decide in advance whether the proceeds will be spent, moved to another account or reinvested. This makes the maturity date part of the plan rather than an afterthought.
Bottom line:
Treasury bills are easy to understand once you separate the purchase price, maturity value, tax treatment and market risk. The strongest choice is not automatically the bill with the highest headline yield. Look at your timeline, after-tax return, access needs and reinvestment plan before committing the money.
Common Treasury Bill Mistakes + an Illustrative Real-Life Example
Treasury bills are easier to use when the investment is planned around the money’s purpose. Many mistakes happen because an investor sees an attractive yield, chooses a bill without checking the timeline, or forgets what happens after the bill matures. Here are the mistakes worth avoiding.
6 Common T-Bill Mistakes to Avoid
1. Confusing the discount with the yield
A T-bill’s discount from face value is not automatically its annualized investment return. Discount rates and investment yields use different calculation methods.
2. Chasing the highest headline rate
A slightly higher yield may not be useful if the maturity does not match your cash needs. The best-looking rate on the screen is not automatically the best fit.
3. Putting emergency cash into T-bills
T-bills can be sold before maturity through the secondary market, but they are not everyday spending accounts. Keep money needed for immediate emergencies in a place designed for quick access.
4. Forgetting the tax advantage
Comparing a T-bill with a taxable cash investment using headline yields alone can miss the effect of state and local income taxes.
5. Ignoring the maturity date
The maturity date determines when the planned proceeds become available. A bill that ends at the wrong time can leave you needing to rearrange your cash plan.
6. Having no plan for the proceeds
A T-bill eventually matures. Decide ahead of time whether the money will be spent, moved to an account or reinvested rather than making that decision at the last minute.
Illustrative Example: A $25,000 Short-Term Investment
Imagine an investor has $25,000 that is not needed immediately but is earmarked for a known short-term goal. The investor considers a newly issued T-bill with a face value of $25,000. For illustration only, assume the purchase price is $24,600.
If the investor holds the bill until maturity and the terms in this illustration apply, the Treasury would pay the $25,000 face value. The $400 difference between the purchase price and face value represents the return before taxes in this simplified example.
Important: The $400 difference is not the annualized T-bill yield. The actual annualized return depends on the purchase price and the bill’s term, using the applicable Treasury yield calculation.
Now consider the planning side. If the investor knows the $25,000 will be needed around the bill’s maturity date, the investment has a clear purpose. If the money might be needed much earlier, the investor should consider a more accessible cash option or understand the consequences of selling the T-bill before maturity.
How Much Can $25,000 Earn in Treasury Bills?
The practical lesson:
Start with the purpose and timing of the money, then compare available yields, taxes and access. The purchase price tells you what you pay today; the face value tells you what a newly issued bill pays at maturity. The time between those two points is what makes the return meaningful.
If you are deciding between Treasury bills and other short-term cash options, compare them with money market accounts or review our CD vs. Treasury bills comparison.
Who Should Choose Treasury Bills?
Treasury bills can be a useful fit when money has a defined short-term purpose and you know roughly when you may need it. They are less about choosing an investment because of your age or account balance and more about matching a Treasury maturity with a specific cash need. Treasury Bills for Emergency Funds
T-Bills May Fit You If…
You have a defined short-term goal
If you expect to use the money around a known date, a T-bill’s defined maturity can make the cash easier to plan around.
You want short-term U.S. government securities
T-bills are direct obligations of the U.S. government, which may appeal to investors who want short-term government securities rather than bank deposits.
State or local taxes matter to you
Treasury interest is generally subject to federal income tax but exempt from state and local income taxes. That treatment can matter when comparing after-tax returns with taxable alternatives.
You want to spread out maturity dates
Instead of putting all short-term money into one maturity, an investor can use different T-bill maturity dates to create a more staggered cash-flow plan. What Is a Treasury Bill Ladder?
What About Retirees and Conservative Investors?
Retirees and conservative investors may use T-bills for money earmarked for near-term expenses. A defined maturity can help with planning for a known cash need, while the credit quality of the U.S. government may appeal to investors who place a high priority on limiting credit risk.
That does not mean T-bills need to replace every other part of a financial plan. A retiree might keep some money readily accessible for immediate expenses while using T-bills for a later spending need. A conservative investor might also combine different maturities rather than committing all short-term cash at once.
T-Bills May Not Be the Best Fit If…
- You need the money for everyday spending.
A T-bill is a security, not a checking or savings account, so it is not designed for routine transactions. - Your timeline is highly uncertain.
If you may need the money unexpectedly, an accessible deposit account may be easier to manage. - You are investing for long-term growth.
T-bills have short maturities, so they may not by themselves address the growth needs of a long-term investment plan.who should buy Treasury bills
A useful rule:
Treasury bills often make the most sense when the money has a clear short-term job and a reasonably clear timeline. If you need day-to-day access or are focused mainly on long-term growth, another account or investment may serve that purpose better.
Treasury Bills FAQ: 8 Common Questions Beginners Ask
Once you understand the purchase price, face value, maturity and yield, Treasury bills are fairly straightforward. These eight questions cover the practical details investors commonly want to know before adding T-bills to a short-term savings or investment plan.
1. What are Treasury bills?
Treasury bills, commonly called T-bills, are short-term U.S. government securities with maturities of one year or less. Newly issued bills are generally sold for less than their face value. Unlike Treasury notes and bonds, T-bills generally do not make periodic coupon payments. Instead, an investor generally receives the bill’s face value at maturity. The difference between the purchase price and the amount received at maturity represents the return before taxes.
2. How do Treasury bills make money?
A newly issued T-bill generally generates its return through the difference between its purchase price and face value. For example, an illustrative $10,000 face-value bill might cost less than $10,000. If it is held until maturity, the investor receives the $10,000 face value, with the difference representing the return before taxes. The annualized yield depends on the purchase price and the bill’s term, so the dollar discount should not be mistaken for the annualized investment yield.
3. Are Treasury bills safe?
T-bills are generally considered to have very low credit risk because they are direct obligations of the U.S. government. They are not FDIC-insured bank deposits. If a newly issued T-bill is held until maturity, the investor’s expected payment is based on the Treasury’s obligation to pay the bill’s face value. Selling before maturity introduces market-price risk because the security’s value can change before the maturity date.Are Treasury Bills Safe? Risks, Safety & 2026 Guide
4. How are Treasury bills taxed?
Treasury bill interest is generally subject to federal income tax but exempt from state and local income taxes. For a bill issued at a discount, the difference between the purchase price and the amount received at maturity is generally treated as interest income. Treasury interest is generally reported on Form 1099-INT in Box 3. Tax treatment can be more involved when securities are sold before maturity or when other transactions are involved, so unusual situations may require guidance from a qualified tax professional.
5. Where can I buy Treasury bills?
Individuals can buy Treasury bills directly through TreasuryDirect or through many brokerage accounts. TreasuryDirect provides access to Treasury auctions. A brokerage may also provide access to new Treasury issues and, depending on the firm, the secondary market. Account requirements, available features and pricing policies can differ, so check the terms of the platform you plan to use.
6. Can I sell a Treasury bill before it matures?
Yes. Treasury bills can be sold before maturity in the secondary market through a brokerage that supports Treasury trading. The price you receive can be different from the price you originally paid because market conditions change over time. As a result, selling early can produce a different gain or loss than holding the bill until maturity.
7. Are Treasury bills better than CDs or savings accounts?
Not necessarily. Treasury bills may appeal to investors who want short-term U.S. government securities, defined maturities and the state and local tax exemption available for Treasury interest. Savings accounts and money market accounts generally provide easier access to cash, while CDs can offer a fixed rate for a selected term. Eligible deposits at FDIC-insured banks are covered within applicable insurance limits. The better option depends on the purpose of the money, access requirements, tax situation and available return.
For a focused comparison, see our CD vs. Treasury bills guide.
8. What happens when a Treasury bill matures?
At maturity, a newly issued T-bill reaches its scheduled payment date and the investor receives the bill’s face value according to the applicable Treasury payment terms. The proceeds can then be used for the original financial goal or directed toward another investment. If you continue buying T-bills, each new purchase has its own maturity date, purchase price and yield. Using different maturities can also help create a staggered schedule for future cash needs.
Quick takeaway:
Treasury bills are short-term U.S. government securities with a discount-based return. Before buying, pay attention to the maturity date, the applicable yield measure, taxes, access to your money and your plan for the proceeds.
Treasury Bills Final Verdict: Are T-Bills Worth Considering?
Treasury bills can be a useful part of a short-term money strategy when the investment has a clear purpose and a defined time frame. A newly issued T-bill is generally purchased for less than its face value and, when held to maturity, pays its face value. That simple structure can make T-bills easier to plan around than investments whose value or maturity is less predictable.
Their appeal goes beyond the purchase-price discount. T-bills are direct obligations of the U.S. government, can be purchased through TreasuryDirect and many brokerages, and receive favorable state and local tax treatment. Treasury interest is generally subject to federal income tax but exempt from state and local income taxes.
Treasury bills may make sense when you:
- Have money earmarked for a short-term goal
- Know approximately when you will need the money
- Prefer short-term U.S. government securities
- Want to consider the state and local tax treatment of Treasury interest
When T-Bills May Not Be the Right Tool
A T-bill is not a substitute for every type of cash or investment account. Money needed for everyday purchases or unexpected expenses may be better kept in an accessible deposit account. A CD may be worth comparing when a bank deposit with a fixed term is the priority. For long-term goals, investors may need a broader strategy rather than relying primarily on short-term Treasury securities.
There is also a practical consideration if your plans change. Holding a newly issued T-bill until maturity follows the original maturity schedule, while selling before maturity exposes you to the market price at the time of sale. That difference matters if the money could be needed sooner than expected.
A simple way to make the decision
- Decide what the money is for.
- Identify when you expect to need it.
- Compare the relevant T-bill yield with suitable alternatives.
- Consider the effect of federal and state/local taxes.
- Decide what you will do when the T-bill matures.
Final Takeaway
Treasury bills are worth considering when they match the job your money needs to do. They can be a strong short-term option for planned cash, but the best decision comes from looking at the whole picture—not just the advertised yield. Match the maturity to your timeline, understand the tax treatment and keep enough accessible cash outside the T-bill for needs that cannot wait.

Treasury bills and Treasury bonds are both U.S. government debt securities, but they serve very different time horizons. Treasury bills are designed for shorter periods, while Treasury bonds are built for much longer commitments. That difference can affect how often you receive income, how sensitive your investment is to changing interest rates, and how easily the investment fits a near-term or long-term goal. 1
Treasury bills and Treasury bonds are both marketable debt securities issued by the U.S. Department of the Treasury. When you buy one, you hold a debt obligation of the U.S. government. The biggest difference is the length of time until maturity and the way each security provides its return.
The easiest way to understand how Treasury bills make money is to stop thinking of them like a savings account. You usually do not receive a separate interest deposit every month. Instead, the return is built into the price you pay for the bill.
If you are new to Treasury bills, think of a T-bill as a short-term U.S. government security that you can buy for your portfolio. The Treasury issues these securities to borrow money for a limited period. When the bill matures, the Treasury pays its face value. The return generally comes from the difference between the price you paid and the amount received at maturity.
Treasury bills, commonly called T-bills, are short-term debt securities issued by the U.S. Department of the Treasury. They mature in one year or less and are designed to provide a relatively short-term way to invest in a direct obligation of the federal government. Unlike Treasury notes and bonds, T-bills do not make regular coupon payments during their term.
Treasury bills, commonly called T-bills, are short-term debt securities issued by the U.S. Department of the Treasury. In simple terms, you are lending money to the U.S. government for a defined period. The Treasury issues the bill with a stated face value and pays that face value when the bill matures, subject to the terms of the security.
When you apply for a money market account, the financial institution needs to establish your identity before opening the account. Federal customer-identification rules require covered institutions to collect certain identifying information, while the methods used to verify that information can vary from one institution to another.
