Take-home pay only tells part of the story. Florida has a cost of living index of 100 while Montana is at 97 (national average = 100).
With similar costs of living (100 vs 97), 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 $77,786 in Montana.
For a single earner at $100K filing jointly, take-home becomes $84,710 in Florida and $81,038 in Montana \u2014 a difference of $3,673. The gap remains similar regardless of filing status.
On paper, moving from Montana to Florida would save $3,673/year on a $100K salary, or $18,363 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $3,673/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.
