Take-home pay only tells part of the story. Hawaii has a cost of living index of 192 while New Jersey is at 115 (national average = 100).
This is a substantial difference. After adjusting for cost of living, $100K in Hawaii has purchasing power of $37,487 compared to $62,728 in New Jersey. New Jersey wins on both raw take-home and cost-adjusted purchasing power, making it the clear winner for a $100K earner.

On paper, moving from Hawaii to New Jersey would save $163/year on a $100K salary, or $813 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $163/year, the tax difference alone likely isn’t worth relocating for. Other factors — job market, lifestyle, family — should drive the decision. The tax savings are a nice bonus if you’re already considering the move for other reasons.
