Quick Answer: Are T-Bills Worth It?
T-Bills are worth it if you want guaranteed returns, state tax exemption, and zero risk on money you don't need for up to a year. They are not worth it for long-term wealth building or passive income.
| Situation | Worth It? | Why |
|---|---|---|
| Short-term cash parking (under 1 year) | ✅ Yes | Guaranteed return, no risk |
| Emergency fund storage | ✅ Yes | Safe, earns more than savings |
| High state-tax investor (CA, NY, NJ) | ✅ Yes | State tax exemption adds real value |
| Large cash holding over $250,000 | ✅ Yes | No FDIC limit unlike bank accounts |
| Long-term wealth building (5+ years) | ❌ No | Stocks outperform significantly |
| Monthly income needed | ⚠️ Partial | Only a 4-week rolling ladder delivers true monthly cash flow — see Monthly Income Calculator |
| Beating inflation long-term | ⚠️ Partial | Only works when rates exceed inflation |
How to Decide If T-Bills Are Worth It for You
- Choose T-Bills: if you don’t need the money for 1–12 months
- Choose T-Bills: if you live in a high-tax state
- Avoid T-Bills: for long-term investing (stocks outperform)

T-Bills vs High-Yield Savings Account
The HYSA is the most common alternative. Here is the honest comparison:
| Feature | T-Bills | High-Yield Savings |
|---|---|---|
| Typical Rate (2026) | 4.3–4.7% | 3.8–4.5% |
| Rate Type | Fixed at purchase | Variable — can drop anytime |
| State Tax | ✅ Exempt | ❌ Fully taxable |
| Access to Money | Fixed maturity date | Withdraw anytime |
| Safety | U.S. Gov backed | FDIC up to $250K |
| Best For | Money you won't need for 1–12 months | Emergency fund, daily access |
Compare your specific rates side by side with tax impact included.
T-Bills vs CDs
CDs are the closest competitor to T-Bills. The headline rate comparison looks close — but state taxes change the math significantly, especially in high-tax states.
| Feature | T-Bills | CDs |
|---|---|---|
| Typical Rate (2026) | 4.3–4.7% | 4.0–5.0% |
| State Tax | ✅ Exempt | ❌ Fully taxable |
| Early Withdrawal | Sell on secondary market (brokerage) | Penalty — typically 3–6 months interest |
| FDIC Insurance | Not needed — gov backed | Up to $250,000 |
| Min. Investment | $100 | $500–$1,000 (varies) |

T-Bills vs Stocks
This is the most misunderstood comparison. T-Bills and stocks are not competing — they serve completely different jobs. You would not compare a parking lot to a skyscraper.
| Feature | T-Bills | S&P 500 Stocks |
|---|---|---|
| Average Annual Return | 4–5% (current rates) | ~10% historically (not guaranteed) |
| Risk | Zero — government guaranteed | High — can lose 30–50% in a crash |
| Time Horizon | Days to 1 year | 5+ years recommended |
| Volatility | None | High |
| Tax | Ordinary income (state exempt) | Capital gains (preferential rates) |
| Best For | Preservation, short-term | Long-term wealth building |
The State Tax Advantage — Where T-Bills Really Shine
This is where T-Bills really pull ahead. By federal law, T-Bill earnings skip state and local tax entirely. Most investors in high-tax states underestimate how much this is worth.
| State | State Tax Rate | T-Bill After-Tax Yield | CD After-Tax Yield | T-Bill Advantage |
|---|---|---|---|---|
| Texas / Florida | 0% | 3.90% | 3.90% | Neutral |
| Pennsylvania | 3.07% | 3.90% | 3.78% | +0.12% |
| New York | 8.82% | 3.90% | 3.56% | +0.34% |
| Oregon | 9.9% | 3.90% | 3.51% | +0.39% |
| California | 13.3% | 3.90% | 3.38% | +0.52% |
In California, a 5% T-Bill is worth the same as a CD paying 5.9% — a rate almost no bank offers. That gap is entirely due to state tax. If your bank cannot beat 5.9%, your T-Bill is the better deal — no calculation needed.

Are T-Bills Beating Inflation in 2026?
A 4.5% yield sounds good — but if prices are rising 3.5% a year, your actual gain in purchasing power is only about 1%. That is your real return. Here is how T-Bills have stacked up against inflation across different periods:
| Scenario | T-Bill Yield | Inflation Rate | Real Return | Verdict |
|---|---|---|---|---|
| 2022 (high inflation) | ~1.5% | ~8% | −6.5% | ❌ Losing to inflation |
| 2023–2024 (peak rates) | ~5.3% | ~3.2% | +2.1% | ✅ Beating inflation |
| 2026 (current est.) | ~4.5% | ~2.8% | +1.7% | ✅ Beating inflation |
Who Should Invest in T-Bills?
✅ T-Bills Are Worth It For:
- Investors with cash sitting idle for 1–12 months
- Anyone in a high state-tax state (CA, NY, NJ, OR)
- Emergency fund holders who want yield without risk
- Retirees or near-retirees protecting capital
- Investors with over $250K cash (bypasses FDIC limits)
- People waiting for a better stock market entry point
- Businesses parking operational cash
❌ T-Bills Are NOT Worth It For:
- Long-term investors (5+ year horizon) — stocks win
- People needing instant daily access to cash
- Investors in 0% state tax states — CD advantage disappears
- Anyone seeking regular monthly income (T-Bills pay at maturity)
- Investors chasing inflation-beating returns over decades
How to Make T-Bills Worth It
Once you decide T-Bills make sense for you, these three moves make the biggest difference:
1. Roll Over Frequently in Rising Rate Environments
When interest rates are rising, shorter-duration T-Bills (4-week, 8-week, or 13-week) let you reinvest at higher rates sooner. The 17-week is also a good middle ground — shorter than 26 weeks but less rollover work than 4-week. Locking into a 52-week T-Bill during a rising rate period means you miss out on better rates as they increase.
See how much you earn rolling over T-Bills multiple times over 1–5 years.
2. Use a T-Bill Ladder for Liquidity + Yield
Split your cash across multiple T-Bills of different durations. With a 4-week rolling ladder, one bill matures every week — the closest you can get to monthly cash flow from T-Bills. Longer-duration ladders give periodic lump sums, not monthly payments.
Build a personalized ladder and see monthly cash flow projections.
3. Choose the Right Duration
The wrong duration can cost you returns or lock up cash you need. Five minutes choosing the right one is worth it.

Final Verdict: Are T-Bills Worth It in 2026?
In 2026, T-Bills are offering real positive returns above inflation, a significant state tax advantage over bank products, and zero credit risk. For short-term cash management, they are genuinely one of the best options available to US investors right now.
They are not a replacement for stocks, bonds, or a diversified long-term portfolio. They are the best place for money you need to keep safe, liquid within a year, and working harder than a savings account.
