Compare the current yield for a similar term, the date you need the money, taxes, and what happens if you withdraw or sell early. A Treasury bill may appeal if its maturity matches your goal and state or local tax exemption matters; an insured CD may fit if you want a bank deposit with a competitive rate and clear account terms.
CDs and Treasury bills at a glance
| Feature | Treasury bills | CDs |
|---|---|---|
| What they are | Short-term U.S. Treasury securities, not bank deposits. | Bank deposits held for a stated term. |
| Typical terms | 4, 6, 8, 13, 17, 26, or 52 weeks, according to TreasuryDirect. | Commonly three months to five years or more, according to the FDIC. |
| How earnings work | Usually bought at a discount or at par and redeemed at face value at maturity; the difference is interest. | Earn interest under the bank’s stated APY and account terms. |
| Taxes | Interest is federally taxable and exempt from state and local income taxes. | Tax treatment depends on the account and the saver’s circumstances; check applicable tax guidance. |
| Protection | Not covered by FDIC deposit insurance. | Eligible deposits at insured banks are covered within applicable FDIC limits. |
| Early access | Can be sold before maturity, but the market price may differ from the purchase price. | Withdrawal rules and any penalty depend on the specific CD contract. |
How to decide which fits your savings goal
Start with the date you need the money
Choose a maturity that ends before or on the date you expect to use the savings. Treasury bills have the listed terms above; CDs offer terms set by each institution. If you may need the money sooner, assess the cost and uncertainty of early access rather than assuming either product is instantly available without a trade-off.

Compare yields for the same time and term
Compare the CD’s current APY with the Treasury bill’s current auction investment yield for a similar maturity. A bill’s discount rate and investment rate are different measures; TreasuryDirect explains the bill pricing conventions on its bill information page. Rates change, so a dated average is context, not a live offer or a forecast.
For context only, the FDIC national-rate table as of April 20, 2026 reported averages of 1.25% for 3-month CDs, 1.44% for 6-month CDs, and 1.53% for 12-month CDs (FDIC national rates). Those are national averages based on reported deposit-rate data, not the best available offers or October 2026 quotes. No October 2026 bill auction yield is established here, so these figures cannot show which product currently pays more.
Account for taxes
The IRS states that interest from Treasury bills, notes, and bonds is subject to federal income tax but exempt from state and local income taxes (IRS Publication 550, 2025). Treasury bills are generally issued at a discount, with the difference between the purchase price and face value generally treated as interest income when paid at maturity. The value of the state and local exemption depends on your location and tax circumstances; compare estimated after-tax returns rather than assuming the exemption makes a bill the winner.
Check protection and account terms
FDIC insurance covers eligible deposits at an insured bank, dollar-for-dollar including principal and accrued interest, up to the applicable limit. The standard maximum is $250,000 per depositor, per insured bank, per ownership category; count your other deposits at that bank when assessing coverage (FDIC deposit insurance). A Treasury bill is a security, not an FDIC-insured deposit.
What to know about Treasury bills
Treasury bills are electronic securities issued for terms from four weeks to 52 weeks. TreasuryDirect lists regular maturities of 4, 6, 8, 13, 17, 26, and 52 weeks. The minimum purchase is $100, in $100 increments. Most listed terms are auctioned weekly; 52-week bills are auctioned every four weeks. The rate is set at auction, and the return comes from the difference between the purchase price and face value at maturity (TreasuryDirect).

TreasuryDirect says, “You can hold a bill until it matures or sell it before it matures.” Selling early is not the same as cashing out at a guaranteed price: the market price can be above or below what you paid.

A CD holds money for a specified term in exchange for interest. Its exact conditions vary by institution and product. Before opening one, review the account agreement and disclosures for:
Quick Recap
Rank #4
- APY and how interest is compounded or credited.
- Early-withdrawal rules and any penalty or restrictions.
- Whether the CD has a call feature that could let the bank close it early. The FDIC notes that some market-linked and longer-term high-yield CDs may be callable.
- What happens at maturity, including renewal instructions and any grace period.
- Whether your total eligible deposits at the bank and ownership category remain within the FDIC insurance limit.
A practical comparison before you commit
- Set the goal date. Write down when you expect to need the money and choose a bill or CD term that aligns with it.
- Get current, comparable rates. Check the CD APY and the bill’s auction investment yield for similar terms, at the same time.
- Estimate after-tax earnings. Include federal taxes and, for a Treasury bill, consider the state and local income-tax exemption in light of your own circumstances.
- Read the early-access terms. For a CD, check the institution’s withdrawal provisions. For a bill, consider that an early sale may produce a different price than the purchase price.
- Verify protection and purchase details. Confirm whether the CD deposit is eligible for FDIC coverage and whether your combined deposits at that bank affect coverage. For a bill, confirm the minimum and purchase channel.
Which should you choose?
- Consider a Treasury bill if a bill maturity matches your savings date and the state and local tax exemption improves the after-tax result for your situation.
- Consider a CD if you find a competitive APY for the term you need, value a bank deposit, and are comfortable with the account’s withdrawal and maturity rules.
- Pause before locking the money away if you may need it early. A CD’s contract may impose costs or restrictions; selling a bill early exposes you to market-price changes.
