How this calculator works

Bank interest (savings, money market and CDs) is ordinary income to West Virginia and to the IRS. After-tax yield = APY × (1 − federal rate − West Virginia rate − local rate).

Treasury bills, notes and bonds are taxed only federally: federal law bars states from taxing their interest (31 U.S.C. 3124). After-tax yield = T-bill yield × (1 − federal rate).

The West Virginia rates are its 2026 brackets as compiled by the Tax Foundation from state law. Choose the bracket your taxable income falls in; the calculator starts at the rate for a single filer with $75,000 of taxable income (4.82%).
