Take-home pay only tells part of the story. Georgia has a cost of living index of 93 while Louisiana is at 91 (national average = 100).
With similar costs of living (93 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: $79,500 in Georgia vs $83,915 in Louisiana.
For a single earner at $100K filing jointly, take-home becomes $79,520 in Georgia and $81,948 in Louisiana \u2014 a difference of $2,428. The gap remains similar regardless of filing status.
On paper, moving from Georgia to Louisiana would save $2,428/year on a $100K salary, or $12,138 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $2,428/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.
