The differences look small but compound into real dollars depending on where you live and how flexible you need to be.\n\nThis guide does the after-tax math, names where to buy each, and tells you which wins in the most common situations in 2026.\n\n## What changed in 2026\n\nA few details matter when you're choosing between the two.\n\n- **T-bill auctions are easier than ever.** TreasuryDirect's interface is still ugly but works, and most brokers will buy them for you commission-free.\n- **Brokered CDs got more competitive.** Schwab and Fidelity routinely list CDs that match or beat T-bills on headline rate.\n- **Bank CD penalties got stiffer.** Some banks now charge 6 months of interest for early withdrawal on a 12-month CD. Read the fine print.\n\n## How we picked\n\nWe weighted what determines after-tax return and flexibility.\n\n- **Headline yield**\n- **State tax exemption** (T-bills only)\n- **Liquidity / early withdrawal cost**\n- **Where to buy** — friction matters\n- **FDIC vs Treasury backing** — both fully safe, technically different\n\n## 1. T-bills — best for state-tax-burdened savers\n\nT-bills are obligations of the US Treasury, exempt from state and local income tax. If you live in California, New York, or another high-tax state, that 5–10% effective tax savings often outweighs a slightly lower headline rate vs a CD.\n\nBuy them at TreasuryDirect (no fee, slightly clunky) or any major broker (no fee, much nicer interface). Auctions happen weekly for 4-, 8-, 13-, and 26-week durations.\n\n## 2. Brokered CDs — best for hands-off laddering at scale\n\nSchwab, Fidelity, and Vanguard all sell CDs from dozens of banks at fixed terms. They're FDIC-insured up to $250k per bank, settle like bonds, and you can sell them on the secondary market if you need to (at market price, which may be less than face).\n\nThe catch: if you sell early, you get whatever a buyer will pay, not your principal. Don't confuse \"liquid\" with \"no loss.\"\n\n## 3. Bank CDs — best when promotional rates beat both\n\nOccasionally a credit union or online bank will run a promo CD that beats both T-bills and brokered CDs after tax. They exist; they're not common in 2026; and they usually have early-withdrawal penalties measured in months of interest.\n\n## Comparison: T-bills vs CDs in April 2026\n\n| Product | Yield (approx) | State tax? | Liquidity | Best for |\n| --- | --- | --- | --- | --- |\n| 4-week T-bill | ~4.4% | Exempt | Mature in 4 wks | High-tax states |\n| 26-week T-bill | ~4.5% | Exempt | Mature in 6 mo | Locked rate, tax-friendly |\n| 6-month brokered CD | ~4.6% | Taxable | Sell at market | No-state-tax savers |\n| 12-month bank CD | ~4.5% | Taxable | Penalty to break | Promo rate hunters |\n| HYSA | ~4.2% | Taxable | Daily | Emergency cash |\n\n## Common mistakes to avoid\n\n**Comparing yields pre-tax.** A 4.6% CD in California is worth ~4.2% after state tax. A 4.5% T-bill is worth 4.5%. Always compare net.\n\n**Laddering badly.** Buying ten 4-week T-bills doesn't beat one 26-week T-bill if rates are flat. Match maturity to when you'll actually need the money.\n\n**Forgetting reinvestment risk.** A 4-week T-bill rolls into the next auction's rate, which may be lower. A 12-month CD locks today's rate.\n\n## FAQ\n\n**Are T-bills safer than CDs?**\nBoth are essentially as safe as it gets. Treasuries are backed by the US government; CDs by FDIC up to $250k per bank.\n\n**Where do I buy T-bills?**\nTreasuryDirect.gov for direct buys, or any major broker (Fidelity, Schwab, Vanguard) which is much easier and still free.\n\n**Can I lose money on a T-bill?**\nNot if you hold to maturity. If you sell early on the secondary market and rates moved against you, the price will be slightly off par.\n\n## Where to go next\n\nFor related guides see [How to buy Treasury bonds in 2026](/blog/how-to-buy-treasury-bonds-2026), [Best CD rates 2026](/blog/best-cd-rates-2026), and [Best high-yield savings accounts 2026](/blog/best-high-yield-savings-accounts-2026).","hue":290,"metaTitle":"T-bills vs CDs 2026: which wins for cash savings","metaDescription":"Treasury bills vs CDs in 2026 — after-tax math, where to buy them, and which beats the other for short-term cash.
