OVERVIEW
Oregon has progressive income tax from 4.75% to 9.9% but no state sales tax. Arizona has a flat 2.5% income tax — the lowest flat rate in the US — but an 8.37% average combined sales tax. On $100,000 income, Arizona residents save approximately $5,630/year in income tax compared to Oregon. However, Oregon's zero sales tax saves ~$4,185/year on $50,000 in spending compared to Arizona. For middle earners spending a lot, the gap narrows. For high earners ($200k+), Arizona's 2.5% cap is dramatically better than Oregon's 9.9% top bracket. Portland vs Phoenix is one of the most interesting inter-regional comparisons for remote workers choosing Pacific Coast vs Southwest lifestyle.

FAQ

Frequently Asked Questions

Does Oregon's no sales tax actually beat Arizona's lower income tax?

It depends on income vs spending levels. On $100k income with $50k annual spending: Oregon income tax $8,130 + $0 sales tax = $8,130 total. Arizona income tax $2,500 + $4,185 sales tax = $6,685 total. Arizona still wins by $1,445. On $200k income with $60k spending: Oregon $18,130 + $0 = $18,130 vs Arizona $5,000 + $5,022 = $10,022. Arizona wins by $8,108. The higher your income relative to spending, the more Arizona wins.

What is Oregon's income tax rate structure for 2026?

Oregon 2026 income tax uses 4 brackets: 4.75% ($0-$18,400), 6.75% ($18,401-$46,200), 8.75% ($46,201-$250,000), and 9.9% above $250,000. With the Oregon standard deduction (~$2,420 single), effective rates on $100k gross are approximately 8.13%. Portland metro residents also face a 1% Multnomah County income tax and a Metro supportive housing services tax, which can push effective rates above 10%.

Is Arizona's 2.5% flat tax really the lowest in the US?

Yes, as of 2026, Arizona's 2.5% flat income tax is the lowest flat rate among states that levy a flat income tax. The Arizona flat tax replaced the old progressive bracket system and took effect starting in 2023, fully implemented at 2.5% by 2024. States with no income tax (FL, TX, NV, WA, WY, SD, AK) still beat Arizona, but among flat-tax states, 2.5% is the lowest in the US.

Portland vs Phoenix: which is better for high-income remote workers?

Phoenix wins dramatically on taxes for high earners: a $300k income earner pays ~$26,130 in Oregon (9.9% top bracket) vs $7,500 in Arizona (2.5% flat) — saving $18,630/year. Over 10 years: $186,300. Portland adds Multnomah County taxes on top. Phoenix offers a growing tech scene, lower property tax, and 299 sunny days. Portland wins on: culture, green space, no sales tax on purchases, and no extreme heat. For high earners, the tax math overwhelmingly favors Phoenix.

Do Oregon residents really pay no sales tax at all?

Yes, Oregon has no state or local sales tax. This is one of only 5 states with no sales tax (along with NH, MT, DE, AK). Oregon shoppers pay $0 on groceries, clothing, electronics, and most goods. This saves the average Oregon household $2,000-$4,000/year compared to high-sales-tax states. However, Oregon funds its government through high income taxes (up to 9.9%), which more than offsets the sales tax savings for middle and high earners.
