recoverable by switching

On a $25,000 balance, the gap is about $1,005 a year before tax. After Rhode Island's 5.99% top income-tax rate on the additional interest, you keep about $945. Because Treasury interest is exempt from Rhode Island income tax, routing that cash through a state-tax-exempt Treasury vehicle can recover most of the difference.

Why Rhode Island changes the math

Rhode Island taxes interest income at a top rate of 5.99%. Treasury interest is exempt from that tax, giving higher-income Rhode Island savers a moderate after-tax edge from T-Bills or a government money market fund.

Living costs across Rhode Island run above the national average, close to those of its larger New England neighbors, sizing typical emergency funds accordingly.

Cost of living in Rhode Island 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 Rhode Island 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 Rhode Island tax high-yield savings account interest?
Yes. Rhode Island treats savings interest as taxable income, with a top rate of 5.99%. Interest from U.S. Treasury bills and the Treasury portion of a government money market fund is generally exempt from Rhode Island income tax, which can change the after-tax winner for higher earners.
Is a high-yield savings account worth it in Rhode Island?
Yes. Even after Rhode Island 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 Rhode Island savers?
They can be for higher earners. Because Treasury interest is exempt from Rhode Island 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.
