Where to keep cash in Alaska

Alaska 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 Alaska

Treasury bills are free of state income tax everywhere, but in Alaska 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.

Alaska taxes on cash, in brief

No state income tax on interest.
Interest on U.S. Treasury bills, notes and bonds: exempt from state and local income tax, taxed federally.
