3-month T-bills are yielding around 3.71% with a state-tax exemption and zero default risk, while dividend ETFs pay a similar yield with real market risk attached. Here's how to decide how much of your cash belongs in each.
If you've got cash you want working harder than a checking account but you're not ready to take on real market risk, you've probably run into two very different pitches: Treasury bills, boring, government-guaranteed, and currently paying a genuinely competitive rate, or dividend ETFs, which pay you regularly too, but come with real ups and downs in the underlying share price. Understanding how they actually differ, not just their yield, but their risk, taxes, and liquidity, makes it a lot easier to decide how much of your money belongs in each.
A Treasury bill, or T-bill, is a short-term loan to the US government, you buy it below its face value, and when it matures (anywhere from 4 weeks to 52 weeks depending on the term you choose), you get paid the full face value, with the difference being your return. As of mid-July 2026, the 3-month T-bill was yielding around 3.71%, which is a genuinely strong rate for something backed by the full faith and credit of the US government with essentially no default risk. You can buy T-bills directly through TreasuryDirect.gov with no fees, or through most brokerage accounts, which is often more convenient if you already hold other investments there.
A dividend ETF is a single fund that holds a basket of dividend-paying stocks, giving you a slice of income from many companies at once instead of picking individual stocks yourself. Dividend-focused ETFs like SCHD are currently yielding somewhere in the 3.5%-4.0% range, competitive with T-bills on paper, but that yield comes attached to a share price that moves with the stock market, meaning your principal can go up or down in value even while you keep collecting the dividend.
This is the detail that changes the math for a lot of people: interest from Treasury bills is exempt from state and local income tax, though it's still subject to federal tax. If you live in a state with meaningful income tax, that exemption can make a T-bill's real, after-tax yield noticeably better than its headline rate suggests compared to a savings account or CD paying a similar rate but taxed at both the federal and state level. Dividend ETF payouts, by contrast, are generally taxed as ordinary income or at qualified dividend rates depending on how long you've held the shares, with no special state-tax exemption.
A T-bill locks your money up until its maturity date, but since terms run as short as 4 weeks, that's a pretty minor commitment, and you can also sell a T-bill on the secondary market before maturity if you need the cash sooner, though you may get slightly more or less than face value depending on where rates have moved. A dividend ETF is fully liquid, you can sell shares any day the market is open, but you're exposed to real price swings: a market downturn can shrink your principal by more than a year of dividends would have paid you, even if the dividend itself keeps getting paid.
Just like a CD ladder, you can stagger T-bills across multiple maturities, say 4-week, 13-week, and 26-week bills, so that a portion matures on a rolling basis, giving you predictable, regular access to cash while still capturing the higher short-term rate. Some people build a hybrid approach: keep a T-bill ladder for money they might need in the next year, and put money with a longer time horizon into a dividend ETF, accepting more short-term volatility in exchange for the potential of the share price itself growing over time, something a T-bill, which simply returns your principal at maturity, can never do.
Neither option requires much capital to begin. Treasury bills through TreasuryDirect start at a minimum purchase of $100, in $100 increments after that, making it genuinely accessible even if you're just testing the waters with a small amount. Dividend ETFs are even more flexible at most modern brokerages, since fractional share investing means you can put in as little as $5 or $10 and still own a proportional slice of the fund. Neither product requires you to choose an all-or-nothing amount, which makes it easy to start small with either one, or both, while you get comfortable with how they behave before committing a larger amount.
Take Felix and Aisha, each investing $20,000 they don't need immediately but want accessible within a couple of years. Felix builds a T-bill ladder across 13-week and 26-week bills, capturing roughly 3.7% annually with virtually no risk to his principal and a portion of his money maturing every few months. Over a year, he earns close to $740 in interest, all exempt from his state's income tax, and his $20,000 principal is fully intact regardless of what the stock market does.
Aisha puts her $20,000 into a dividend ETF yielding about 3.8%, earning a similar $760 in dividends over the year. But her principal isn't guaranteed the way Felix's is: if the market has a rough year and the ETF's share price drops 8%, she's down roughly $1,600 in principal value even after collecting her dividends, an outcome that simply isn't possible with a T-bill. Conversely, if the market has a strong year and the ETF appreciates 8%, she comes out well ahead of Felix on a total-return basis. Neither approach is wrong, Felix optimized for certainty, Aisha for growth potential, and the right split between the two depends on how much volatility you can actually tolerate for money you might need in the next year or two.
Treating a dividend ETF's yield as equivalent to a T-bill's yield without accounting for the very different risk to your principal. A similar headline number doesn't mean a similar risk profile.
Ignoring the state tax exemption on Treasury interest when comparing to a CD or savings account paying a similar rate, especially in higher-tax states where the after-tax gap can be meaningful.
Locking money into a long-term T-bill or CD that you might actually need sooner, when a laddered approach with shorter maturities would have given nearly the same rate with much better flexibility.
Putting money you'll need within the next year into a dividend ETF for the extra yield, then being forced to sell during a downturn at a loss because the timing didn't line up with the market's own timeline.
Decide how soon you might realistically need this money, that answer should drive the split between T-bills (safety, short time horizons) and dividend ETFs (growth potential, longer time horizons).
If you're new to T-bills, start with a TreasuryDirect account or check whether your existing brokerage offers them with no added fee, both are straightforward once set up.
Consider laddering T-bills across a few maturities (like 13 and 26 weeks) rather than putting everything into one term, so you're not waiting on a single date for any of your money to become available.
If you go with a dividend ETF, be honest with yourself about your time horizon, money you might need within a year probably doesn't belong in something that can lose value in the short term.
Treasury bills and dividend ETFs both pay you regularly, but they're solving different problems: T-bills protect your principal with a government guarantee and a genuine tax advantage, while dividend ETFs trade some short-term certainty for the potential of real growth over time. A lot of people don't need to pick one exclusively, using T-bills for money with a shorter time horizon and dividend ETFs for money you can leave alone for years is a reasonable way to get some of both without betting everything on either approach.
