Take-home pay only tells part of the story. Connecticut has a cost of living index of 111 while Oregon is at 110 (national average = 100).
With similar costs of living (111 vs 110), 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 $66,082 in Oregon.
For a single earner at $100K filing jointly, take-home becomes $80,167 in Connecticut and $78,275 in Oregon \u2014 a difference of $1,892. The gap remains similar regardless of filing status.
On paper, moving from Oregon to Connecticut would save $1,892/year on a $100K salary, or $9,458 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $1,892/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.
