Should You Move from Oklahoma to Mississippi?
On paper, moving from Oklahoma to Mississippi would save $776/year on a $100K salary, or $3,879 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $776/year, the tax difference alone likely isn’t worth relocating for. Other factors — job market, lifestyle, family — should drive the decision. The tax savings are a nice bonus if you’re already considering the move for other reasons.
