Take-home pay only tells part of the story. Kansas has a cost of living index of 90 while New Hampshire is at 108 (national average = 100).
This is a substantial difference. After adjusting for cost of living, $100K in Kansas has purchasing power of $83,887 compared to $73,264 in New Hampshire. Interestingly, Kansas wins on purchasing power even though New Hampshire has higher raw take-home pay. The cost of living difference more than offsets the tax advantage.
For a single earner at $100K filing jointly, take-home becomes $81,083 in Kansas and $84,710 in New Hampshire \u2014 a difference of $3,627. The gap remains similar regardless of filing status.
On paper, moving from Kansas to New Hampshire would save $3,627/year on a $100K salary, or $18,135 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $3,627/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.
