Turn this guide into a decision

Read the guidance, then compare current options and run the numbers for your situation.

How to choose

What to weigh before you pick

It usually comes down to 3 things. Compare your options on each before deciding.

Fees

Account fees and fund expense ratios that compound over time.

Account & fund options

Account types, available investments, and tools.

Service & platform

App quality, research, and human support when needed.

Key Takeaways
  • 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

Original maturity
Treasury bill
One year or less
Treasury note
More than one year
How you get paid
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
If you need the cash early
Treasury bill
The sale price can differ from what you paid
Treasury note
The sale price can differ from what you paid
Best used for
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.

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.

Frequently Asked Questions

What is the main difference between a Treasury bill and a note?
Treasury bills mature in one year or less, and you buy them for less than their face value (the gap between what you pay and what you get back at maturity is your return). Treasury notes run longer and pay you interest every six months along the way. Which one fits better depends on when you'll need the cash and how you want it paid out.
Can a Treasury note lose value before maturity?
If you sell it before maturity, a Treasury note's market price can be higher or lower than what you paid for it. That matters if the date you need the cash doesn't line up with the note's actual maturity date.
Are Treasury bills better for an emergency fund?
A Treasury bill can work as a later layer of your reserves once you have a known timing window, but the portion you might need without any notice belongs in cash you can get to immediately.
