Best HYSA in Colorado (2026)
HYSA APYs are set at the national level — Colorado residents get the same top options as everyone else: Pibank Savings 5.50% APY, BrioDirect 5.30%, Varo 5.00%, Marcus 4.80%, Ally 4.75%. What differs is after-tax yield: Colorado's 4.44% state income tax brings combined effective tax to ~28% for middle-class filers, netting ~3.94% after all taxes.

The honest answer about "state-specific" HYSA rates
HYSA APY is set by each bank at the national level; there is no state-by-state pricing. A savings account marketed to Colorado residents will pay the same APY as one marketed in any other state. The only meaningful state-level variables are:
- State income tax on interest. Colorado taxes HYSA interest at up to 4.44% state rate.
- Local credit unions. Small statewide credit unions occasionally run promotional first-tier APYs above the national online-HYSA average. Rarely competitive above $10K.
- Branch availability. Non-issue for online HYSAs but matters if you want in-person deposits.
