How to choose
What to weigh before you pick
It usually comes down to 3 things. Compare your options on each before deciding.
Account fees and fund expense ratios that compound over time.
Account types, available investments, and tools.
App quality, research, and human support when needed.
- Bills and notes are both tradeable U.S. Treasury securities. What actually matters is whether the maturity date and the way interest is paid out fit your real timeline.
- A bill isn't automatically the same as cash in your pocket, and a note isn't automatically too risky — the trouble starts when a deadline forces you to sell before maturity.
- Only compare which account to hold them in, or state-tax treatment, after you've already decided how soon the money needs to be available.
Decision frame
Does the maturity date land before you'll need the money, even if your plans shift a little earlier?
Compare
The date you'll need to pay for something, the expected cash flow, and the risk of having to sell early — not just the quoted rate.
Verify first
The exact maturity date, the interest-payment schedule, which account holds it, and whether the money can realistically stay invested until maturity.
Do not assume
Don't pick a longer-term note just because its rate is higher if you'd actually need to sell it to reach your goal.
Start with the date, then pick the security
Treasury bills mature in one year or less. Treasury notes run longer and pay you interest every six months. Both can be sold before maturity through a broker. That doesn't make them interchangeable for a near-term goal.
If the money is for an expense coming up in a few months, a bill that matures before that deadline keeps things simple. If the goal is farther out and the date is pretty firm, a note might be a reasonable match. Go in planning to hold it until maturity — not with a backup plan of "I'll just sell it if I need to."
The real difference is how and when you get paid
- Treasury bill
- One year or less
- Treasury note
- More than one year
- Treasury bill
- You buy it for less than face value, then get the full amount back at maturity
- Treasury note
- Interest paid every six months, then your principal back at maturity
- Treasury bill
- The sale price can differ from what you paid
- Treasury note
- The sale price can differ from what you paid
- Treasury bill
- A known short-term date
- Treasury note
- A longer, fairly firm date
Ask yourself one question before buying: Would I still be okay with this choice if I had to sell it next month? If not, don't put money you might need next month into it. A drop in price doesn't mean the Treasury failed to pay you — it means you sold a tradeable security before its scheduled maturity, at whatever price the market offered that day.

Plan your next move
Pre-tax estimates. For illustration only — not financial advice.
Use the calculator to compare cash alternatives you enter yourself, including tax assumptions. It doesn't predict Treasury auction results, sale prices, or future account rates.
Taxes and where you hold it come after the timing decision
Treasury interest is subject to federal income tax but exempt from state and local income tax. That can matter, but it shouldn't override the actual cash date. TreasuryDirect suits a simple, direct hold-to-maturity approach, while a brokerage can make it easier to keep everything in one portfolio or sell early if needed. TreasuryDirect requires a security bought there to stay put for 45 business days before you can transfer it elsewhere.
