Take-home pay only tells part of the story. Florida has a cost of living index of 100 while North Carolina is at 95 (national average = 100).
With similar costs of living (100 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: $79,125 in Florida vs $79,089 in North Carolina.
For a single earner at $100K filing jointly, take-home becomes $84,710 in Florida and $80,720 in North Carolina \u2014 a difference of $3,990. The gap remains similar regardless of filing status.
On paper, moving from North Carolina to Florida would save $3,990/year on a $100K salary, or $19,950 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $3,990/year savings is meaningful but probably not enough to justify a move on its own. However, combined with other factors like career growth, lifestyle preferences, or family proximity, it could tip the scale.
