Side-by-side tax comparison between Oregon (9.9% top rate, graduated) and Utah (4.45% top rate, flat). See which state lets you keep more at every salary level, and how cost of living changes the picture.
Oregon uses a graduated income tax (4.75-9.9%) while Utah has a flat system (4.45% flat). On a $100K salary, Oregon takes $6,435 in state and local taxes compared to Utah’s $4,450 \u2014 a difference of $1,985.
Because Oregon has graduated brackets while Utah is flat, the gap between them changes at different income levels. Oregon’s rates increase with income, so high earners feel the difference more acutely.
Oregon also has local income taxes (estimated at $0/year on $100K), which Utah does not. This widens the gap beyond just state rates.
Utah wins at 10 out of 10 salary levels tested. The advantage exists but is modest across the income spectrum.

Take-home pay only tells part of the story. Oregon has a cost of living index of 110 while Utah is at 99 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $66,082 in Oregon vs $75,429 in Utah. The take-home winner also wins on purchasing power.
For a single earner at $100K filing jointly, take-home becomes $78,275 in Oregon and $80,260 in Utah \u2014 a difference of $1,985. The gap remains similar regardless of filing status.
On paper, moving from Oregon to Utah would save $1,985/year on a $100K salary, or $9,925 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
At $1,985/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.
