recoverable by switching

On a $25,000 balance, the gap is about $1,005 a year before tax. After Vermont's 8.75% top income-tax rate on the additional interest, you keep about $917. Because Treasury interest is exempt from Vermont income tax, routing that cash through a state-tax-exempt Treasury vehicle can recover most of the difference.

Why Vermont changes the math

Vermont taxes interest income at a top rate of 8.75%. Treasury interest is generally exempt from that tax, so the after-tax case for T-Bills or a government money market fund over a fully taxable savings account is meaningful for higher-income Vermont savers.

Living costs across Vermont run above the national average, which sizes typical emergency funds — and the Bank Gap they carry — larger than in many neighboring states.

Cost of living in Vermont is above the national average, which shapes how large an emergency fund needs to be and therefore how many dollars the Bank Gap quietly costs on idle cash.

After-tax tip

Because Vermont taxes savings interest but not Treasury interest, the highest after-tax yield is not always the highest headline APY. Run your tax profile through the short-term savings tool to see whether a Treasury bill or government money market fund beats a taxable account for you.

Frequently asked questions

Does Vermont tax high-yield savings account interest?

Yes. Vermont treats savings interest as taxable income, with a top rate of 8.75%. Interest from U.S. Treasury bills and the Treasury portion of a government money market fund is generally exempt from Vermont income tax, which can change the after-tax winner for higher earners.

Is a high-yield savings account worth it in Vermont?

Yes. Even after Vermont state tax, moving cash from a national-average account to a top high-yield savings account still leaves you with substantially more interest. The Bank Gap is far larger than the state-tax drag on the additional interest.

Are T-Bills better than a HYSA for Vermont savers?

They can be for higher earners. Because Treasury interest is exempt from Vermont income tax, a T-Bill or government money market fund can deliver a higher after-tax yield than a fully taxable savings account at a similar headline rate. The short-term savings calculator computes the breakeven for your exact tax situation.
