If you’re looking for a safe place to invest and grow your money, you might be considering both certificates of deposit (CDs) and U.S. Treasury bills (T-bills). Both investment options offer steady and predictable returns, while protecting your principal. However, there are some key differences between them, including how long you need to lock up your money, initial investment requirements, and how your earnings will be taxed. Read on for a closer look at T-bills vs. CDs.
Key Points
• CDs require locking up money for a term ranging from three months to five years, while T-bills generally have shorter terms — between four weeks to one year — which can make them a good option for short-term savings goals.
• The minimum investment for opening a CD varies by bank but is typically at least $500, while the minimum purchase amount for Treasury bills is $100.
• Interest on CDs is taxed in the year it is earned, whereas Treasury bill interest is taxed when the T-bill is sold.
• CD interest is taxable at both federal and state levels, while T-bill interest is exempt from state taxes.
• If interest rates are expected to fall, it can be advantageous to lock in a high rate on a multi-year CD.
What Is a Certificate of Deposit?
A certificate of deposit, commonly referred to as CD, is a type of savings account offered by banks and credit unions. You can also get CDs through brokerages, called brokered CDs, though these are still issued by banks. When you open a CD, you deposit a set amount of money into the account and agree to leave it there for a specific period of time, which generally ranges from three months to five years.
CDs pay a fixed interest rate that is typically higher than the average annual percentage yield (APY) for savings accounts. If you withdraw your money early, however, you will likely have to pay a penalty, often in the form of interest earned over a certain time period.
Like other types of savings accounts, CDs are insured, which means you get your money back in the unlikely event your bank goes bankrupt. CDs at banks insured by the Federal Deposit Insurance Corporation (FDIC) are typically covered up to $250,000 per depositor, per ownership category, for each insured bank. Co-owners of joint accounts at the same bank are typically each insured up to $250,000. Credit unions offer similar insurance through the National Credit Union Administration (NCUA).
Pros and Cons of CDs
CDs come with a number of benefits, but also have some drawbacks. Here’s a look at some of the top reasons you might or might not want to invest in a CD.
Pros
• Guaranteed returns: CDs offer a fixed interest rate, so you know exactly how much you will earn by the end of the term. Even if market interest rates go down, your CD rate will stay the same.
• Safety: As FDIC- or NCUA-insured products, CDs provide a high level of security, protecting your principal up to $250,000.
• Higher interest rates: CDs typically offer higher interest rates than traditional savings accounts, which can help your money grow faster.
Cons
• Limited liquidity: Funds invested in a CD are locked in for the entire term of the CD. If you need to access your money before the CD matures, you will typically incur a penalty, which can eat into your earnings.
• Could potentially earn more: While guaranteed, the returns on a CD can be lower than what you might earn with more aggressive (aka, higher-risk) investments like stocks or bonds.
• Inflation risk: If the interest rate on your CD doesn’t exceed, or even keep up with, the rate of inflation, the actual purchasing power of your money can erode over the term of the CD.
What Are U.S. Treasury Bills?
Another safe way to invest your money is to buy U.S. Treasury bills. Also called T-Bills or Treasuries, Treasury bills are short-term government securities issued by the U.S. Department of the Treasury. Treasuries are backed by the full faith and credit of the U.S. government and considered one of the safest investments available.
When you buy a T-bill, you pay less than the bill’s face value, which is the amount you will receive at maturity. The difference between the purchase price and the face value at maturity is your interest earned. You’ll owe federal taxes on any income earned, but no state or local tax. T-bills are considered short-term securities because they mature in four weeks to one year.
Pros and Cons of Treasury Bills
Like CDs, Treasuries come with both benefits and drawbacks. Here are some to keep in mind.
Pros
• Safety: T-bills are backed by the U.S. government, making them virtually risk-free if held until maturity.
• Predictable returns: Returns are guaranteed, based on the agreed-upon rate of the Treasury bill that you purchase.
• Tax benefits: The interest earned on a U.S. Treasury bill is exempt from state taxes, which can be a significant advantage for investors in high-tax states.
Cons
• Lower returns: While safe, the returns on T-bills are generally lower than what you can potentially earn by investing in the market over the long term.
• Inflation risk: Like all fixed-rate investments, if the rate you earn on your T-bill doesn’t exceed the inflation rate, the actual purchasing power of your money will diminish over the term of the Treasury.
• Market risk: While treasuries are stable, their value can fluctuate over time. If you sell before the T-bill reaches maturity, you may not get as much interest as you expected.

Comparing CDs vs Treasury Bills
While CDs and Treasury bills have a number of similarities, there are also some key differences that you’ll want to understand before investing in either one. Here’s a closer look.
Tax Implications
One key difference between CDs and Treasuries is that interest on CDs is taxable at the federal and state level. Treasuries, on the other hand, are exempt from state income tax. If you are investing in a taxable account and live in a state with a high income tax, this can make investing in Treasuries attractive.
Another tax difference: With CDs, you pay taxes on interest earned the year it is added to the account, whether you cash out the CD or not. With Treasuries, the interest you earn is only taxable when you sell the T-Bill, which may be a different tax year than the year in which you bought it.
In both cases, the interest you earn will be reported on Form 1099-INT.
Expected Earnings
With both a CD and a Treasury bill, you’ll know beforehand how much interest you’ll earn if you hold it until its maturity. If you sell a CD early, you may forfeit some or all of your expected interest and also possibly pay a penalty. Selling Treasury bills before they reach their maturity may be possible (since there is a secondary market for them) but if you do, you may not earn all the interest you would earn if you held it to its maturity.
Other Key Details to Consider
When deciding whether to put your money in T-bills or CDs, here are some other factors to keep in mind.
• When you’ll need the money: T-Bills are more liquid than CDs since they typically have shorter maturities and can be sold on the secondary market. If you need access to your funds quickly, T-Bills may be the better option. While you can sell a CD before maturity, doing so typically incurs a penalty that can reduce your returns.
• Initial investment amount: The minimum investment for opening a CD varies by bank but is typically at least $500. The minimum purchase amount for Treasury bills is $100. A higher initial investment requirement could make opening a CD difficult if you are just starting out and don’t have a lot of extra cash to invest.
• Interest rate environment: While T-bills and CDs generally offer comparable rates, you may want to consider time to maturity and where interest rates could be headed. If interest rates are expected to fall, for example, locking in a good rate on a multi-year CD could be a smart move.
How To Purchase CDs and Treasury Bills
You can buy CDs directly from banks and credit unions, either online or in-person. Rates and terms vary by institution, so it’s generally a good idea to shop around to find the best CD for your needs. You typically don’t have to have an existing account at a bank or credit union to open a CD.
You can purchase Treasuries either through a brokerage firm or directly from the U.S. Department of the Treasury at TreasuryDirect.gov. The most commonly offered maturity dates are four weeks, eight weeks, 13 weeks, 17 weeks, 26 weeks, and 52 weeks. T-bills are sold in increments of $100, and the minimum purchase is $100.
Similar Investments to Keep in Mind
If you are looking for a relatively safe place to park your savings and earn a decent return, there are other options besides T-bills and CDs. Here are some to consider.
• Series I savings bonds: I bonds are a type of U.S. savings bond with an overall rate that is based on both a fixed rate that never changes and a variable interest rate,designed to keep up with inflation, that resets every six months. You need to hold the bond for at least one year and will pay a penalty if you cash out before five years. Like T-bills, interest payments are exempt from state taxes.
• Money market fund: A money market fund is a type of mutual fund that invests in CDs, short-term bonds, and other low-risk investments. The money you invest is liquid, and yields are typically higher than regular savings accounts. However, the funds are not protected by the FDIC or NCUA.
• High-yield savings account: While not technically an investment, high-yield savings accounts pay more than the average APY for savings accounts, while offering more liquidity than CDs or T-Bills. Your money is insured, but the APY on a high-yield savings account isn’t fixed, meaning it can rise or fall depending on market rates.
The Takeaway
CDs and Treasury bills are both considered safe investments, allowing you to earn a guaranteed return without putting your initial investment at risk. However, there are some key differences that can make one a better fit than the other.
T-bills often have shorter terms than CDs, making them a good option for a savings goal that is a year or less down the road, like buying a car. With some terms as long as five years (or more), a CD may work better for a longer-term savings goal, such as making a downpayment on a home. If you’re looking for safety and competitive returns along with liquidity, you might also consider putting your money in a high-yield savings account.

FAQ
Are CDs and Treasury bills considered safe investments?
Yes, both certificates of deposit (CDs) and Treasury bills (T-bills) are considered safe investments. CDs offer a fixed interest rate over a specified term, and are typically insured up to $250,000, making them low-risk. Treasury bills are short-term government securities backed by the U.S. government, making them one of the safest investments available. They are sold at a discount and mature at face value, with the difference representing the investor’s interest. Both options can be ideal if you’re a conservative investor seeking minimal risk.
Should I keep my emergency fund in a CD or Treasury Bill?
You generally want your emergency funds to remain highly liquid and easily accessible, so a regular savings account can work better than a certificate of deposit (CD) or Treasury bill.
CDs usually require you to leave your funds untouched for a fixed term, with penalties for early withdrawal. Treasury bills also tie up your money, though terms are relatively short (typically four weeks to one year). A Treasury bill might work for an emergency fund if you have other funds you can tap in a pinch before the maturity date. Otherwise, consider keeping your emergency cash in a high-yield savings account or a money market account.
How do CDs and Treasury bills differ from savings bonds?
Certificates of deposit (CDs), Treasury bills, and savings bonds are all low-risk investments, but there are some key differences between them.
• CDs offer fixed interest over a specific term, and are typically used for short- to medium-term savings goals.
• Treasury bills are short-term government securities that mature in a year or less and are sold at a discount.
• Savings bonds, such as Series I and EE Bonds, are long-term government bonds with interest that compounds semi-annually. They are generally intended for long-term savings goals, such as education or retirement.

SoFi members with direct deposit activity can earn 4.50% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.
As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.50% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.
SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.50% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.
SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.
Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
