Take-home pay only tells part of the story. Connecticut has a cost of living index of 111 while New Jersey is at 115 (national average = 100).
With similar costs of living (111 vs 115), the tax difference is the primary factor. What you see in raw take-home pay is essentially what you get in purchasing power: $67,191 in Connecticut vs $62,728 in New Jersey.
For a single earner at $100K filing jointly, take-home becomes $80,167 in Connecticut and $77,723 in New Jersey \u2014 a difference of $2,444. The gap remains similar regardless of filing status.
On paper, moving from New Jersey to Connecticut would save $2,444/year on a $100K salary, or $12,220 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $2,444/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.
