Take-home pay only tells part of the story. Louisiana has a cost of living index of 91 while North Carolina is at 95 (national average = 100).
With similar costs of living (91 vs 95), the tax difference is the primary factor. What you see in raw take-home pay is essentially what you get in purchasing power: $83,915 in Louisiana vs $79,089 in North Carolina.
For a single earner at $100K filing jointly, take-home becomes $81,948 in Louisiana and $80,720 in North Carolina \u2014 a difference of $1,228. The gap remains similar regardless of filing status.
On paper, moving from North Carolina to Louisiana would save $1,228/year on a $100K salary, or $6,138 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $1,228/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.
