Best HYSA in Washington (2026)
HYSA APYs are set at the national level — Washington 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: Washington has no state income tax, so a 5.50% APY nets ~4.18% after federal tax alone.

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 Washington 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. Washington imposes no state income tax on HYSA interest.
- 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.
