CD vs Treasury Bonds (2026) - When State Tax Exemption Wins

TL;DR: Top-yield 5-year CDs are paying around 4.4%. The 10-year Treasury sits near 4.3%, the 30-year near 4.7%. CDs win on raw yield for short horizons. Treasuries win for any resident of a state with income tax above 5%, and for any saver who wants a market they can sell into tomorrow. Pick by state tax rate, horizon, and whether you might need to exit early.

The CD-vs-Treasury decision sounds like a yield comparison and it isn't. It's a tax comparison and a liquidity comparison. Headline yields on the two instruments are usually within 30 basis points of each other - close enough that the state income tax exemption on Treasury interest is what actually swings the answer.

California taxes interest at up to 13.3%. New York up to 10.9%. Oregon 9.9%. New Jersey 10.75%. If you live in one of these states and you buy a CD instead of a Treasury at the same headline yield, you are paying that state tax for no reason - because Treasury interest is exempt under 31 U.S.C. Section 3124. Florida, Texas, Tennessee, Nevada, Washington, Wyoming, South Dakota, Alaska, and New Hampshire residents don't have this tilt - for them the comparison comes back to FDIC vs full-faith-and-credit, and to whether the buyer expects to need the money before maturity.

Side-by-side comparison

Current yield (2026)	~4.30-4.50% (5yr top tier)	~4.30% (10yr), ~4.70% (30yr)
Federal tax	Taxable	Taxable
State income tax	Taxable	Exempt (31 USC 3124)
Default risk	FDIC to $250K per depositor	U.S. Treasury full faith and credit
Liquidity before maturity	Early withdrawal penalty (3-12 months of interest)	Sell on secondary market - price moves with rates
Price volatility if sold early	Penalty fixed, principal returned in full	Can lose 15-30% of principal if rates rise
Minimum purchase	$500-$1,000 typical	$100 via TreasuryDirect

Best for	Sub-5yr horizons, tax-free states	10yr+ horizons, high-tax states

When CDs win

You live in a no-income-tax state. The state-tax shield is worth nothing to you. Take the higher headline yield.
Your horizon is 5 years or less. CDs return par at maturity. A 10-year Treasury sold at year 5 has interest-rate risk.
You want certainty of principal return. Early-withdrawal penalty on a CD is small and known. Selling a 30-year Treasury into a rate spike can wipe out 25% of principal.
You're under $250K and want simplicity. FDIC is automatic, no TreasuryDirect account, no brokerage statement.
You want to ladder small dollar amounts. $5K-$10K rungs are easy at any bank. Treasuries work too but the brokerage friction is higher.

When Treasury Bonds (10/20/30yr) wins

You live in California, New York, Oregon, New Jersey, Hawaii, or Minnesota. The state-tax exemption alone is worth 40-100 basis points of after-tax yield.
You want to lock a yield for 20-30 years. No CD goes that long. The 30-year Treasury at 4.7% with no reinvestment risk is the right tool.
You're investing more than $250,000 with one institution. FDIC caps at $250K per depositor per bank. Treasuries have unlimited backing.
You want pure interest-rate exposure for portfolio duration matching. Treasuries are the standard. CDs are a deposit, not a duration instrument.
You might need to exit if rates fall. A Treasury you bought at 4.7% becomes a capital gain if 30-year yields drop to 3.5%. A CD never appreciates - you just get par.

Worked example: $250,000 over the planning horizon

You're a California resident in the 35% federal / 10.3% state bracket. You have $250,000 and a 10-year horizon. Two options:

Option A: 5-year CD at 4.4%, roll into a new 5-year CD at year 5 (assume same rate).
Annual interest: $11,000. State tax: $1,133. Federal tax: $3,850. After-tax: $6,017/yr. 10-year after-tax total: $60,170.

Option B: 10-year Treasury at 4.3%.
Annual interest: $10,750. State tax: $0. Federal tax: $3,762. After-tax: $6,988/yr. 10-year after-tax total: $69,880.

The Treasury wins by $9,710 over 10 years - despite a lower headline yield - purely because California doesn't get a cut. And the Treasury has zero reinvestment risk at year 5, which the CD strategy assumed away.

Flip the scenario to a Texas resident: same 4.4% CD vs 4.3% Treasury, no state tax. CD pays $11,000 vs $10,750 - take the CD. Same math, opposite answer, decided entirely by zip code.

Tax implications

CD interest is taxable as ordinary income at both federal and state levels, reported on Form 1099-INT in the year credited (even if you don't withdraw it - phantom income on multi-year CDs is real). Treasury interest is taxable federally but exempt from state and local income tax under federal statute. This exemption applies to T-bills, T-notes, T-bonds, TIPS, I-Bonds, and EE bonds.

For a high-tax-state resident in the top federal bracket, the state exemption is worth 60-130 basis points of equivalent after-tax yield. That means a 4.30% Treasury beats a 4.80% CD on after-tax basis in California. Always compute the comparison after tax, not before.

If the bonds are held in an IRA or 401(k), the state-tax exemption is irrelevant - everything inside the wrapper is tax-deferred or tax-free at withdrawal. Use Treasuries in a taxable brokerage account where the exemption actually matters.

Where a MYGA fits in

A 5-7 year MYGA at 5.40-5.85% beats both the CD and the Treasury on headline yield, and the gain is tax-deferred until withdrawal - which is the third tax tool in this comparison. A CD spits out a 1099 every year. A Treasury spits out coupon income every six months. A MYGA compounds gross inside the contract.

For a retiree who doesn't need the income, who's already in a high tax bracket from RMDs and Social Security, and who plans to either annuitize at age 75 or 1035-exchange into another deferral vehicle, the MYGA's tax-deferral can be worth 40-80 bps of effective annual yield over a 5-year horizon vs. the CD. State guaranty fund covers $250K-$300K of cash value per owner per carrier - similar shape to FDIC but issued by the state insurance department, not FDIC. The MYGA is illiquid (surrender charge schedule), so it's not a substitute for a Treasury you might sell.

Frequently Asked Questions

Are Treasury bonds safer than CDs?

Both are essentially default-free under $250K. CDs rely on FDIC, which is backed by the full faith and credit of the U.S. government via the FDIC's Deposit Insurance Fund. Treasuries are direct obligations of the U.S. government. Same backstop, different wrapper. Above $250K per bank, the Treasury is the only one with unlimited coverage.

Why is the state tax exemption such a big deal?

Because most savers compare headline yields and forget about it. A California top-bracket resident effectively keeps about 56% of CD interest after federal + state tax. The same resident keeps about 65% of Treasury interest. That 9-point gap is worth 70-90 basis points on a 4% instrument - more than most yield curve premiums.

Can I sell a Treasury before maturity?

Yes, on the secondary market through any brokerage. But the price will reflect current interest rates. If you bought a 30-year at 4.7% and rates rise to 6%, your bond is worth roughly 75 cents on the dollar. A CD, by contrast, returns par minus a fixed early-withdrawal penalty (usually 3-12 months of interest) regardless of rate moves.

Should I buy Treasuries on TreasuryDirect or through a brokerage?

TreasuryDirect is free with no markup but the interface is dated and you can't sell from there. A brokerage like Fidelity, Schwab, or Vanguard offers free new-issue Treasury auctions plus the ability to sell on the secondary market. For most investors, the brokerage path is better - particularly if you want to ladder.

What about brokered CDs?

Brokered CDs sit between a bank CD and a Treasury. They're still FDIC-insured per issuing bank, but they trade on a secondary market like bonds, so you can sell early at market price (with mark-to-market risk). Yields are usually 10-30 bps higher than direct bank CDs. They're a legitimate middle path but lose the simplicity advantage of a direct bank CD.

How does the 30-year Treasury compare to a 30-year CD?

There is no 30-year CD. The longest CDs commonly available are 10 years, and only at a few institutions. For a 20-30 year locked yield, Treasuries are essentially the only option in the cash-like universe (besides a deferred annuity).

What if I want both - yield AND state tax exemption?

Municipal bonds. For high-bracket residents of high-tax states, in-state munis give you both federal AND state tax exemption. We cover that comparison in detail on the CD vs municipal bonds page.
