Take-home pay only tells part of the story. Indiana has a cost of living index of 90 while Michigan is at 91 (national average = 100).
With similar costs of living (90 vs 91), the tax difference is the primary factor. What you see in raw take-home pay is essentially what you get in purchasing power: $84,639 in Indiana vs $82,280 in Michigan.
For a single earner at $100K filing jointly, take-home becomes $81,760 in Indiana and $80,460 in Michigan \u2014 a difference of $1,300. The gap remains similar regardless of filing status.
On paper, moving from Michigan to Indiana would save $1,300/year on a $100K salary, or $6,500 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $1,300/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.
