Where to keep cash in New Hampshire
New Hampshire has no income tax on interest, so Treasury bills’ state-tax exemption is worth nothing here and the highest rate wins. Today that’s the CFG Bank 1-year CD at 4.65%, keeping about $7,324 a year after federal tax on $250,000.
Why the highest rate wins in New Hampshire
Treasury bills are free of state income tax everywhere, but in New Hampshire there’s no state tax on interest to save. So compare the rates directly, after federal tax: a CD, savings account or Treasury bill paying more keeps more. Treasury bills still have two advantages: U.S. government backing with no $250,000 limit, and the ability to sell any day.
New Hampshire taxes on cash, in brief
- No state income tax on interest. New Hampshire repealed its tax on interest and dividends starting in 2025.
- Interest on U.S. Treasury bills, notes and bonds: exempt from state and local income tax, taxed federally.
