On paper, moving from Idaho to Nevada would save $5,300/year on a $100K salary, or $26,500 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 $5,300, 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 $10,600/year.
