On paper, moving from Hawaii to Washington would save $7,150/year on a $100K salary, or $35,750 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
With an annual savings of $7,150, the tax difference alone is significant enough to justify a move for many people — especially if career opportunities are comparable. At higher salaries, the savings grow even larger: a $200K earner would save $14,300/year.
