Alaska doesn't tax interest income, so after tax the highest yield wins. Safety, liquidity, minimums, fees and effort still differ, so set your weights below.

Our rule: Never ranked by affiliate payout. Payout data isn't an input to the score, and labelled affiliate links never change an option's position. How we make money
Not financial or tax advice. CashRanq is an independent information site that publishes the same general rankings for every reader; scores and presets are not recommendations for you. Rates change often and may depend on balance, eligibility or promotions; money market fund yields are past 7-day yields and are not guaranteed, and funds are not FDIC insured. Tax figures are simplified estimates (marginal rates only; no local taxes, AMT, NIIT, deductions or credits). Always verify the current rate and terms with the provider and consult a tax professional for your situation.
