Take-home pay only tells part of the story. Oregon has a cost of living index of 110 while Wisconsin is at 93 (national average = 100).
This is a substantial difference. After adjusting for cost of living, $100K in Oregon has purchasing power of $66,082 compared to $79,734 in Wisconsin. Wisconsin wins on both raw take-home and cost-adjusted purchasing power, making it the clear winner for a $100K earner.
For a single earner at $100K filing jointly, take-home becomes $78,275 in Oregon and $79,738 in Wisconsin \u2014 a difference of $1,463. The gap remains similar regardless of filing status.
On paper, moving from Oregon to Wisconsin would save $1,463/year on a $100K salary, or $7,313 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $1,463/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.
