Do You Pay Federal Tax on Treasury Bills?
Do You Pay Federal Tax on Treasury Bills?
Yes, Treasury bills are generally subject to federal income tax. If you are asking, do you pay federal tax on Treasury bills, the key point is simple: T-bill interest is taxable at the federal level. Treasury bills are U.S. government securities, but that does not make their interest exempt from federal income tax. At the same time, Treasury bill interest is generally exempt from state and local income taxes. IRS guidance explains this distinction for Treasury obligations.
The way T-bill interest is earned can also look different from a bank savings account or CD. Treasury bills are generally issued at a discount and mature at face value. For a standard T-bill held to maturity, the difference between the purchase price and the amount received at maturity is generally treated as interest income for federal tax purposes. Applicable Treasury interest is generally reported on Form 1099-INT, Box 3.
Understanding these rules can make it easier to compare Treasury bills with other short-term investments. For a broader explanation of maturities, pricing, auctions, and tax treatment, see our complete Treasury Bills guide.

| Main tax benefit | Generally exempt from state and local income taxes |

Complete Beginner Guide to T-Bill Federal Tax
Understanding federal tax on Treasury bills starts with one simple rule: interest from Treasury bills is generally subject to federal income tax. A T-bill is issued by the U.S. Treasury, but that does not make its interest federally tax-free. At the same time, Treasury bill interest is generally exempt from state and local income taxes. See the IRS guidance on Treasury interest for the applicable federal tax rules.
1. How Do Treasury Bills Create Taxable Income?
Treasury bills are generally issued at a discount instead of paying regular coupon interest. For example, an investor could pay $9,800 for a T-bill with a $10,000 maturity value. If the bill is held to maturity, the $200 difference is generally treated as interest income for federal tax purposes.
2. Is the Entire T-Bill Amount Taxable?
No. In a standard purchase held to maturity, the amount originally invested is not itself the interest income. The taxable interest component is generally the difference between the purchase price and the amount received at maturity. The exact treatment can differ for certain transactions, including purchases or sales in the secondary market.
3. When Is T-Bill Interest Reported?
For a standard Treasury bill held to maturity, the IRS generally provides that the interest is reported when the bill is paid at maturity. Selling a T-bill before maturity can involve different tax considerations, so investors should retain purchase, sale, and maturity records.
4. Where Does Treasury Interest Appear?
Treasury interest is generally reported on Form 1099-INT, Box 3. IRS instructions identify Box 3 for interest on U.S. savings bonds and Treasury obligations. Investors should use the tax documents and records applicable to their specific transaction.
EASY WAY TO REMEMBER: Treasury bill interest is generally taxable at the federal level, generally exempt from state and local income taxes, and generally reported as Treasury interest in Box 3 of Form 1099-INT.
How Federal Tax on T-Bills Works
The federal tax treatment of a Treasury bill is easier to understand when you follow the investment from purchase to maturity. A standard T-bill generally does not make periodic coupon payments. Instead, it is issued at a discount and pays its face value at maturity. The difference between the purchase price and the amount received at maturity is generally treated as interest income for federal tax purposes.
Step 1: You Buy the Treasury Bill
For example, a T-bill with a $10,000 maturity value might be purchased for $9,800. The $200 difference is generally the interest income associated with the bill when it is held to maturity. Treasury bills are commonly issued with maturities such as 4, 8, 13, 26, and 52 weeks.
Step 2: The Bill Reaches Maturity
At maturity, the Treasury generally pays the bill’s face value. For a standard T-bill held to maturity, the difference between the purchase price and the maturity amount is generally treated as interest income rather than a separate capital gain.
Step 3: Federal Tax Applies
The interest is generally subject to federal income tax. However, interest from U.S. Treasury obligations is generally exempt from state and local income taxes. This creates an important tax distinction when comparing T-bills with taxable bank deposits.
Step 4: The Interest Is Reported
Treasury interest is generally reported on Form 1099-INT, Box 3. For a standard T-bill held to maturity, cash-method taxpayers generally report the interest when the bill is paid at maturity. A purchase or sale in the secondary market can involve different tax rules and reporting considerations.
THE SIMPLE VERSION: A standard T-bill is generally bought below face value, matures at face value, and the difference is generally treated as federally taxable interest. Treasury interest is generally exempt from state and local income taxes.
Benefits & Drawbacks of Federal Tax on Treasury Bills
Treasury bills are generally subject to federal income tax, but their interest is exempt from state and local income taxes. That combination can affect the after-tax comparison between T-bills and other interest-producing investments. The actual impact depends on the investor’s applicable tax situation and the type of transaction.
Potential Benefits
- State and local tax exemption: Treasury bill interest is generally exempt from state and local income taxes.
- Potential after-tax advantage: In a comparison with an otherwise similar taxable investment, avoiding applicable state and local income taxes can increase the amount of interest retained after those taxes.
- Federal tax treatment is identifiable: Treasury interest is generally reported separately in Box 3 of Form 1099-INT, making it easier to identify the Treasury portion of reported interest income.
Potential Drawbacks
- Federal tax still applies: The state and local exemption does not make Treasury bill interest federally tax-free.
- After-tax results vary: The value of the state and local exemption depends on the applicable tax rules and the investment being compared.
- Different transactions can have different rules: Buying or selling a T-bill in the secondary market can create additional tax and reporting considerations.
QUICK TAKE: The main tax benefit of Treasury bills is the general exemption from state and local income taxes. Federal income tax still applies, so comparing the complete after-tax result is more useful than looking only at the stated T-bill yield.
T-Bills vs. CDs vs. Savings vs. Money Market
Federal tax treatment can help explain an important difference between Treasury bills and common bank deposit products. Treasury bill interest is generally subject to federal income tax but exempt from state and local income taxes. Interest earned from bank CDs, savings accounts, and bank money market accounts is generally subject to federal income tax, while state and local treatment depends on the applicable rules.
| Investment | Federal Tax | State & Local Income Tax | Common Federal Reporting |
|---|---|---|---|
| Treasury Bills | Generally applies | Generally exempt | Form 1099-INT, generally Box 3 |
| Bank CDs | Generally applies | Depends on applicable state and local rules | Generally Form 1099-INT when reportable |
| Savings Accounts | Generally applies | Depends on applicable state and local rules | Generally Form 1099-INT when reportable |
| Bank Money Market Accounts | Generally applies | Depends on applicable state and local rules | Generally Form 1099-INT when reportable |
One Important Distinction
A bank money market account is different from a money market mutual fund. A bank money market account is a deposit account that generally pays interest. A money market fund is an investment product, and its distributions can have different tax-reporting characteristics. This comparison refers specifically to bank money market accounts.
QUICK TAKE: Treasury bills have a specific federal, state, and local tax distinction: their interest is generally federally taxable but exempt from state and local income taxes. For bank deposit products, state and local treatment can differ. Compare the applicable tax rules along with yield, maturity, liquidity, and account terms.
Costs, Tax Risks & Expert Tips
Treasury bills generally do not pay periodic coupon interest. Instead, they are commonly issued at a discount and pay their face value at maturity. For a standard T-bill held to maturity, the difference between the purchase price and the amount received at maturity is generally treated as interest income for federal tax purposes. Other transactions can involve different tax rules.
Costs to Check
- Transaction costs: If buying through a brokerage, check the firm’s pricing, bid-ask spread, or other applicable transaction costs.
- After-tax return: Compare the T-bill’s yield after considering applicable federal tax and its state and local tax exemption.
- Recordkeeping: Keep purchase confirmations, maturity information, sale records, and tax forms with your investment records.
Tax Risks to Understand
- Federal tax still applies: Treasury bill interest is generally subject to federal income tax.
- Tax forms are not the only consideration: Not receiving a Form 1099-INT does not by itself remove an applicable tax-reporting obligation.
- Early sale: Selling a T-bill before maturity can involve tax and reporting considerations that differ from a standard held-to-maturity transaction.
Expert Tips for Cleaner Tax Reporting
For a standard T-bill held to maturity, keep the original purchase price and maturity amount available when reviewing your tax records. Treasury interest is generally reported on Form 1099-INT, Box 3. If a T-bill is sold before maturity or purchased in the secondary market, review the transaction records and applicable tax rules carefully.
EXPERT TIP: Keep your Treasury purchase, maturity, sale, and tax records together. For transactions outside a standard held-to-maturity purchase, consult the applicable IRS guidance or a qualified tax professional when needed.
Common Mistakes + Real-Life Example
Federal tax on Treasury bills is generally straightforward when a standard bill is purchased and held to maturity. Still, investors can misunderstand the state-tax exemption, overlook their tax records, or assume that an early sale follows exactly the same rules.
Mistake 1: Assuming T-Bills Are Completely Tax-Free
Treasury bill interest is generally exempt from state and local income taxes, but it is generally subject to federal income tax. The state and local exemption should not be confused with complete tax-free treatment.
Mistake 2: Ignoring Form 1099-INT
Treasury interest is generally reported in Box 3 of Form 1099-INT. Investors should review their tax documents and keep their own purchase, maturity, and transaction records. The absence of a tax form does not by itself determine whether income is reportable.
Mistake 3: Overlooking an Early Sale
A standard T-bill held to maturity has relatively straightforward treatment. Selling before maturity or buying a T-bill in the secondary market can involve additional tax and reporting rules, so the transaction records matter.
Real-Life Example: A $10,000 T-Bill
Suppose an investor buys a $10,000 face-value T-bill for $9,800 and holds it until maturity. The Treasury pays $10,000 at maturity, creating a $200 difference. For a standard T-bill held to maturity, that difference is generally treated as interest income for federal tax purposes. Treasury interest is generally exempt from state and local income taxes and generally appears in Box 3 of Form 1099-INT.
KEY LESSON: Treasury bills can receive a state and local income-tax exemption without being federally tax-free. For a standard held-to-maturity T-bill, keep the purchase and maturity records and review the applicable Treasury interest reported for federal tax purposes.
Who May Consider Treasury Bills?
Treasury bills may be relevant to investors looking at short-term U.S. government securities and evaluating how federal, state, and local taxes affect their interest income. Their tax treatment can be one factor when comparing T-bills with other short-term investments.
T-Bills May Be Relevant to Investors Who:
- Want exposure to a U.S. Treasury security with a short maturity, generally 52 weeks or less.
- Want to account for the general state and local income-tax exemption on Treasury interest.
- Are comparing securities that are generally issued at a discount and pay face value at maturity.
- Understand that Treasury bill interest is generally subject to federal income tax.
- Want to compare potential after-tax income across different short-term investments.
KEEP IN MIND: Tax treatment is only one factor in evaluating a Treasury bill. Maturity, yield, liquidity, transaction costs, federal taxes, and the tax treatment of alternative investments can also affect the overall comparison.
