Moving from Idaho to Washington: FAQ.
Is the tax savings worth the move?
For high earners, yes. WA household earning $200K pays $0 state income tax; Idaho would charge ~$11,000/year. Even with WA's higher sales tax (~$2,500/year more) and cost of living (~15-20% higher), net financial outcome favors WA for most tech/professional households. Plus WA salaries are typically 10-20% higher for comparable roles.
