Treasury Bills Vs Cds In 2026: Which Pays Better For Short-Term Business Capital Storage?

As a self-employed business owner or solo founder, deciding where to park short-term business capital—cash you'll need within 12 months—is one of the most overlooked decisions in personal finance. You've already weathered irregular 1099 income, managed quarterly estimated taxes, and optimized your business structure. But where that operating capital sits between now and when you need it makes a tangible difference to your bottom line.

Most self-employed professionals compare Treasury bills and CDs based solely on the advertised interest rate. That approach ignores a critical tax advantage: Treasury interest is exempt from state and local income taxes, while CD interest gets hit with federal, state, and local tax rates. For a freelancer or small business owner in a high-tax state, that distinction can mean the difference between 4.15% after-tax returns and closer to 3% after Uncle Sam and your state government take their cut.

This article breaks down exactly how much each option returns to your bottom line, accounts for the tax reality self-employed people face, and shows you how to calculate which choice actually nets you more money in 2026. We'll also show you the specific scenarios where a premium CD rate beats Treasuries—and they do exist.

How much do Treasury bills currently yield compared to certificates of deposit?

Short answer: Six-month Treasury bills yield 4.09% annualized and 12-month bills yield 4.15%, while the national average CD rates stand at 2.678% for 6-month CDs and 2.846% for 12-month CDs as of July 2026. However, the best 6-month and 1-year CDs from select online banks and credit unions reach 4.75% to 5.00% APY.

As of July 23, 2026, the Treasury yield curve shows clear separation between short-term government debt and what traditional banks are paying on deposits. The 6-month Treasury bill carries an annualized yield of 4.09%, according to Forbes Advisor's treasury rates tracker. Move out to 12 months, and the government-backed option yields 4.15% annualized. These rates reflect the Federal Reserve's benchmark federal funds rate of 3.50% to 3.75%, which the Fed held steady through July 2026 amid ongoing inflation considerations.

When you cross over to the CD market, the picture becomes more complex. According to Monitor Bank Rates' survey of national CD rates as of July 24, 2026, the average 6-month CD pays just 2.678% APY, while the average 12-month CD yields 2.846% APY. These figures represent a year-over-year decline—both products fell fractionally from the previous week, signaling the market response to the Fed's rate-holding stance. The gap between these national averages and Treasury bills is a staggering 1.4 to 1.5 percentage points.

But here's where self-employed business owners need to dig deeper: national averages mask the reality of competitive online banking. According to CNBC Select's 2026 analysis, the best CD rates available hover between 4.00% and 4.10% APY for short- and mid-term certificates. More aggressively, WealthView reported in mid-2026 that the best 6-month and 1-year CDs from select online banks and credit unions reach 4.75% to 5.00% APY. These premium rates exist but require active shopping and often require minimum deposits of $25,000 to $100,000—capital many small business owners maintain for operating reserves.

The Federal Reserve's continued rate-hold strategy creates a compressed yield environment. According to Bankrate's 2026 CD rate forecast, the highest rate for one-year CDs in 2026 was predicted to be 3.5% APY, down about one percentage point from 2025 levels. This forecast underestimated the premium CD market's ability to attract deposits with higher rates, but it signals where the broader market trajectory heads as Fed uncertainty subsides.

What are the tax implications of Treasury bills versus CDs for self-employed people?

Short answer: Treasury interest is exempt from state and local income taxes, while CD interest is fully taxable at federal, state, and local rates—a distinction that can swing the after-tax comparison by 1 to 2 percentage points depending on your tax bracket and location.

This is the hidden advantage that shifts the entire Treasury-versus-CD decision for self-employed professionals. According to NerdWallet's investing guide, Treasury interest income is exempt from state and local income taxes—a benefit that exists whether you hold bills, notes, or bonds. The federal government still taxes Treasury interest at ordinary income rates, but the state and local exemption creates a material advantage when you're self-employed and paying both federal self-employment tax (an additional 15.3% on top of your income tax rate) and state income taxes on your business earnings.

Let's work through the math with a real scenario. Suppose you're a self-employed consultant in California with $100,000 in business capital you need to keep accessible for 12 months. You're in the 24% federal tax bracket and pay California's 9.3% state income tax. You're deciding between a 12-month Treasury bill yielding 4.15% and a premium CD yielding 4.85% APY.

Treasury bill scenario: You invest $100,000 in 12-month Treasury bills at 4.15% yield. Interest earned: $4,150. Federal tax at 24%: $996. State tax: $0 (Treasury interest is state-tax-exempt). After-tax return: $4,150 - $996 = $3,154. Effective after-tax yield: 3.15%.

Premium CD scenario: You invest $100,000 in a 4.85% APY CD. Interest earned: $4,850. Federal tax at 24%: $1,164. California state tax at 9.3%: $451. After-tax return: $4,850 - $1,164 - $451 = $3,235. Effective after-tax yield: 3.235%.

In this example, the premium CD barely outperforms the Treasury, despite its 70-basis-point higher nominal rate. The Treasury wins if you're in a higher state tax bracket, or if premium CD rates fall below 4.75% APY. If you're self-employed in a no-income-tax state like Texas or Florida, the calculation shifts further toward CDs, since you lose the state tax advantage. But for the majority of self-employed professionals in moderate-to-high-tax states, the Treasury tax exemption creates substantial hidden value.

The federal tax treatment of both products is identical: interest income is taxed as ordinary income, which means it's added to your 1099 net profit and subject to your marginal federal tax rate. However, Treasury interest does not increase your self-employment tax liability, while CD interest technically counts as "other income" for Schedule C purposes (though it doesn't increase your SE tax base). For self-employed people, this distinction prevents an additional 15.3% tax hit on Treasury interest that would otherwise apply to business earnings.

Which option should you choose for your short-term business capital: Treasury bills or CDs?

Short answer: Choose Treasury bills if you're in a moderate-to-high federal tax bracket in a state with significant income tax; choose premium CDs (4.75%+ APY) only if available in your state and if you're willing to lock up capital for the full term.

The decision hinges on three variables: your state's income tax rate, the specific CD rates available to you, and your certainty about not needing the capital before maturity. Treasury bills offer simplicity, state tax exemption, and modest but reliable yields backed by the full faith and credit of the U.S. government. CDs offer FDIC insurance (up to $250,000 per bank per depositor) and the potential for higher nominal returns if you find premium rates. But both decisions carry real tradeoffs.

Start by identifying your effective tax bracket. If you're self-employed earning $150,000 in net business income, you're in the 22% federal bracket (as of 2026 tax law). Add your state income tax—New York (8.82%), California (9.3%), Oregon (9.9%), or New Jersey (10.75%) residents face meaningful state levies. Add together your federal and state marginal rates: that's the rate at which Treasury bills begin to look attractive. Once your combined marginal rate exceeds 30%, the Treasury state-tax exemption usually outweighs even a 75-basis-point CD rate premium. For most self-employed people in high-tax states earning six figures, this threshold is easily crossed.

Next, source the best CD rates available to you. National averages of 2.678% to 2.846% are not worth comparing to Treasuries. You need rates of at least 4.75% APY from specific online banks or credit unions to make a CD competitive on an after-tax basis. Call or visit online banks like Marcus, Ally, or American Express personal savings. Ask about any current CD specials or promotional rates. Some online credit unions offer rates in the 4.75% to 5.00% range but often require membership or a larger minimum deposit. A 30-minute search for the best available CD rate in your state directly impacts your bottom-line return.

Finally, stress-test your timeline assumptions. Treasuries are liquid—you can sell them on the secondary market before maturity, though you may realize a loss if rates have risen. CDs impose early withdrawal penalties (typically three to six months of interest) if you need the money before maturity. If there's more than a 25% chance you'll need your operating capital before 12 months, the penalty risk alone makes Treasuries the safer choice. Self-employed people with irregular cash flow—consultants, freelancers, contractors—should weight this heavily. Your business might land a new client mid-year or face an unexpected expense, and paying a CD penalty defeats the whole exercise.

Step-by-step: How to choose between Treasury bills and CDs for your business capital

Follow these steps to make a data-driven decision specific to your situation:

1. Calculate your after-tax marginal tax rate. Find your federal tax bracket from your last tax return (22%, 24%, or higher for most business owners). Add your state income tax rate. For example, if you're in the 24% federal bracket and California (9.3%), your combined rate is 33.3%. Write this number down—it's your decision threshold.
2. Gather current rate quotes. Go to the U.S. Treasury website or a broker like Fidelity or Schwab and note the current yields on 6-month and 12-month Treasury bills. Check the Forbes Advisor treasury rates tracker for real-time quotes. Then, search at least five online banks and credit unions for their best 6-month and 12-month CD rates. Document the specific APY, minimum deposit, and any terms or conditions. Don't use national averages; use the rates you can actually access.
3. Calculate after-tax returns for each option. For the Treasury bill: multiply the yield by your deposit amount, then subtract federal tax only (your marginal rate × interest earned). For the CD: multiply the APY by your deposit amount, then subtract both federal and state tax (combined marginal rate × interest earned). Compare the net dollar amounts, not the gross percentages.
4. Assess your access needs. How confident are you that you won't need this capital before the maturity date? If there's meaningful uncertainty, apply a risk discount to the CD option. Deduct three months of interest from the CD's projected return as a reserve for a potential early withdrawal penalty. Recalculate the after-tax return. Compare again.
5. Account for insurance and safety. Both Treasuries and CDs are low-risk. Treasury bills carry the backing of the U.S. government and are issued directly by the Treasury Department. CDs carry FDIC insurance up to $250,000 per bank. If your amount exceeds $250,000, spread CDs across multiple banks, or use Treasury bills for the amount above the FDIC limit. This step adds a layer of risk management to your decision.
6. Make the call and set a review date. Once you've done the math, choose the option with the higher after-tax return that also fits your access needs. Document your decision with the rates you used, the calculation, and the expected annual return. Set a reminder to revisit this decision every six months. Interest rate environments shift, and new CD promotions emerge. The best rate today may not be the best rate in six months.
7. Consider laddering as an alternative. If you want to split the difference and reduce timing risk, ladder your capital across both Treasuries and CDs. Invest half in 6-month Treasury bills (currently 4.09%) and half in a 12-month CD at the best available rate. This balances liquidity, after-tax returns, and reduces the impact of a wrong timing call on the full amount.

Treasury bills vs. CDs: Side-by-side comparison

Where should you buy Treasury bills as a self-employed business owner?

Short answer: Purchase Treasury bills directly from TreasuryDirect.gov (no fees, no middleman) or through a broker like Fidelity, Schwab, or Vanguard if you want easier integration with a business brokerage account.

Most self-employed people don't realize they have a choice of where to buy Treasuries, and this choice materially impacts costs. The U.S. Treasury operates TreasuryDirect, a platform where individual investors and business owners can purchase Treasury bills, notes, and bonds directly from the government with zero fees or commissions. You open a free account, fund it via bank transfer, place bids in Treasury auctions (which happen regularly for bills of different maturities), and hold the securities in a digital account. For a self-employed person parking $50,000 to $500,000 in short-term business capital, TreasuryDirect is the path of least cost and simplicity.

However, TreasuryDirect has operational drawbacks for some business owners. The interface is dated, auction timing is fixed, and if you need to sell before maturity (which you shouldn't count on), you must go through a secondary market broker. For self-employed professionals who want Treasuries within a unified brokerage platform alongside business checking, credit cards, and investment accounts, buying through a broker like Fidelity, Charles Schwab, or Vanguard makes sense. You'll pay a small transaction fee (typically $0 to $2.50 per trade at major brokers as of 2026), but you gain integration, account simplicity, and the ability to sell quickly if needed. If you have $100,000 or more in business capital, the broker fees are negligible compared to the convenience.

One often-missed option: some business checking accounts and money market accounts offer Treasury-backed yields without requiring you to actively buy bills. Ask your business bank if they offer Treasury-backed sweep accounts or money market funds. Some do, and you gain the tax exemption without the operational overhead. This option works well for self-employed people who want passive yields without managing separate Treasury purchases.

How do you apply Treasury interest and CD interest toward your quarterly estimated taxes?

Short answer: Both Treasury interest and CD interest count as taxable income on your 1040 Schedule B, and you must include estimated amounts in your quarterly estimated tax calculations, though Treasury interest is not subject to self-employment tax.

This is critical for self-employed people managing quarterly estimated taxes. When you earn interest income from Treasury bills or CDs, that income is reported on Schedule B (Interest and Ordinary Dividend Income) on your Form 1040. For quarterly estimated tax purposes, you add the expected interest income to your projected net business income and make quarterly payments based on the total. Most self-employed people use Form 1040-ES to calculate estimated payments.

The distinction: Treasury interest is NOT subject to self-employment tax (the 15.3% tax that covers Social Security and Medicare for self-employed people), while CD interest technically flows through as "other income" but also is not subject to self-employment tax. This is a small but real advantage of Treasuries and CDs over reinvesting business profits. The self-employment tax exemption means a Treasury bill earning 4.15% doesn't trigger an additional 15.3% tax hit, whereas that same amount earned as business income would.

For example, if you expect to earn $50,000 in net business income for the year and hold a $100,000 Treasury bill yielding 4.15% annually ($4,150 in interest), your total taxable income for estimated tax purposes is $54,150. At a 33% combined federal and state rate (24% federal + 9% state), you'd owe approximately $17,870 in income tax. However, only the $50,000 in business income is subject to self-employment tax (additional $7,650). The $4,150 in Treasury interest is taxed at 24% federal only ($996) plus 9% state ($374), for a total tax burden of $1,370. That's $346 less than if the $4,150 came from business profits ($4,150 × 33% + 15.3% = $2,025).

FAQ: Treasury bills vs. CDs for short-term business capital

Can self-employed people invest in Treasury bills through an IRA?

Yes, you can hold Treasury bills within a Solo 401(k) or SEP-IRA, and doing so adds another tax-advantaged layer to your short-term capital strategy. Treasury bills held inside a Solo 401(k) or SEP-IRA grow tax-deferred, meaning you don't pay federal income tax on the interest until you withdraw funds in retirement. This is especially powerful if you have contribution room in a Solo 401(k)—as of 2026, you can contribute up to $69,000 (or $76,500 if age 50+) in combined employee deferrals and employer contributions. Using some of that room for Treasury bills that compound tax-free dramatically outpaces holding them in a taxable account. However, if you need the capital within 12 months for actual business operations, don't use retirement account space—keep it in a taxable Treasury account where you retain access without penalty.

Are Treasury bills a good place to keep your emergency fund if you're self-employed?

Treasury bills work for business emergency reserves but not personal emergency funds. Self-employed people need 6 to 9 months of living expenses in a truly liquid account—not Treasury bills that take two to three days to sell and settle. For business reserves (capital you'll use for payroll, inventory, or project funding within 12 months), Treasury bills are excellent. For personal emergency savings, keep 3 to 6 months of household expenses in a high-yield savings account earning 4.5% or more APY, where you can access the money within hours. Use Treasuries for business capital that sits separate from your personal emergency fund.

What happens to your Treasury bills or CDs if interest rates drop in the next six months?

If the Federal Reserve cuts rates and Treasury bill yields fall, your current Treasury holdings increase in value on the secondary market (if you need to sell early). Conversely, if rates rise, the value of your Treasuries falls, and you'd realize a loss if forced to sell before maturity. For CDs, rates matter less—you're locked into your rate for the full term, so a drop in market rates actually works in your favor (you hold a higher-yielding CD than newly issued ones). A rise in rates after you buy a CD is neutral—you keep your rate either way. This is why Treasury bills carry more interest rate risk if you need to liquidate early, while CDs eliminate that risk via the lock-in feature. For self-employed people who cannot afford interest rate risk, the certainty of a CD often justifies a lower yield.

Should you ladder Treasury bills instead of buying a single 12-month maturity?

Laddering—buying bills of different maturities and letting them mature in sequence—can make sense if you have a large amount of business capital ($250,000+) and you're uncertain about when you'll need it. For example, invest $50,000 in 3-month bills, $50,000 in 6-month bills, $50,000 in 12-month bills, and $100,000 in a 2-year note. As each tranche matures, you can reinvest it at whatever the current rate is, or withdraw it for business needs. This approach reduces the risk of being forced to sell at an inopportune time if rates have risen. However, it's administratively more complex and only worth considering if you have $250,000 or more and genuine uncertainty about your cash flow timeline. For most self-employed business owners with $50,000 to $150,000 in reserves, a single 12-month Treasury bill or a single premium CD is simpler and nearly as effective.

Do you report Treasury interest separately from CD interest on your tax return?

Treasury interest and CD interest are both reported on Schedule B (Interest and Ordinary Dividend Income) on your Form 1040, but Treasury interest is labeled separately. You'll list CD interest on one line and Treasury interest on another line. Total interest goes into your calculation of taxable income. The separation exists for record-keeping purposes and because Treasury interest has different state tax treatment, but from a federal tax perspective, both are taxable ordinary income. When filing, use Form 1098-INT from your CD provider and Treasury correspondence showing interest earned to document what you report on Schedule B.

How does business structure affect your Treasury or CD strategy?

If you've elected S-corp status or formed an LLC, your Treasury and CD holdings change slightly in tax treatment. S-corp retained earnings can be invested in Treasuries, and the interest income flows to Schedule B and then to the S-corp's Form 1120-S. You personally pay tax on that income via your K-1, but the state tax exemption on Treasury interest still applies at your personal level. If you're a single-member LLC taxed as a sole proprietorship, the treatment is identical to what we've discussed. If you have a multi-member LLC taxed as a partnership, the interest income flows through the partnership return and to your Schedule K-1, but again, Treasury interest remains state-tax-exempt. The bottom line: structure doesn't change the Treasury tax advantage, but it does affect how you report and track the income. Work with a CPA if you want to optimize this within your specific entity structure.

Can you hold Treasury bills in a business savings or checking account?

No. Treasury bills are securities held in a brokerage or TreasuryDirect account, not deposits in a business savings account. However, you can link your business checking account to your brokerage account and transfer funds between them. Many self-employed people keep operating capital in a business money market account (earning 4.5%+ APY at many online banks in 2026) for ultra-liquid reserves, then move capital into Treasury bills or CDs via their brokerage for the amount they won't need in the next 6 to 12 months. This two-tier approach balances liquidity and yield—short-term cash stays in the money market, longer-term capital gets the Treasury or CD treatment.

Treasury bills vs. CDs: What most people get wrong

The biggest mistake self-employed people make is comparing Treasury bills and CDs on nominal yield alone, ignoring taxes entirely. A business owner sees a 4.15% Treasury bill and a 4.85% CD and immediately assumes the CD is better. But after accounting for federal and state income taxes, the Treasury bill often comes out ahead for residents of moderate-to-high-tax states. It's a classic case of chasing yield without measuring after-tax returns.

The second mistake is assuming all CDs pay the same rate. National averages of 2.678% to 2.846% are real—they reflect the median of large national banks and credit unions. But online banks and specialized credit unions actively compete for deposits with rates of 4.75% to 5.00% or higher. Self-employed business owners who accept the average rate without shopping commit themselves to 200+ basis points in lost returns. A 20-minute search for "best CD rates 2026 6-month" in your state could mean an additional $1,000+ in annual interest on $100,000.

The third mistake is underestimating access risk. Self-employed people say "I'll lock up this capital for 12 months," but real business emerges—a new project launches and you need working capital, an unexpected tax bill arrives, an opportunity to hire someone appears. When the emergency hits and you're stuck in a CD with a three-to-six-month interest penalty, the regret is sharp. Treasuries are more forgiving because you can sell them on the secondary market. If your business is volatile or you're in a growth phase, Treasuries are the safer choice despite the slightly lower nominal yield.

The fourth mistake is failing to layer multiple accounts. If you have $300
