Washington, Oregon, and Nevada sit within a few hours of each other on the West Coast, share overlapping tech ecosystems, and offer fundamentally different tax regimes. For founders and investors choosing where to base operations or establish residency, the differences are dramatic — and they just got more complicated.
Washington’s new 9.9% income tax (ESSB 6346, effective 2028) closes the gap with Oregon but creates new advantages over both neighbors in specific areas. Here’s a detailed comparison across every major tax dimension.
(For an overview of ESSB 6346, see Washington’s New Income Tax: What Founders, Investors, Athletes, and High Earners Need to Know. For the full tax landscape, see Washington State Taxes. For a Washington vs. California comparison, see Washington vs. California.)
Income Tax: The Headline Comparison
Washington: 9.9% on household income above $1 million (effective 2028). Below $1 million: 0%. The $1 million standard deduction means the vast majority of residents pay nothing.
Oregon: Progressive brackets from 4.75% to 9.9%. The top rate of 9.9% applies to income above $125,000 (single) or $250,000 (joint). Oregon taxes from dollar one — there is no zero-tax bracket for high earners.
Nevada: No income tax. None. Zero percent on all income regardless of amount.
At $500,000 in income: Washington $0, Oregon approximately $42,000, Nevada $0. At $2 million: Washington approximately $99,000, Oregon approximately $190,000, Nevada $0. At $5 million: Washington approximately $396,000, Oregon approximately $485,000, Nevada $0.
Nevada is cheapest at every income level. Washington is cheaper than Oregon at every income level — and dramatically cheaper below $1 million (where Washington’s tax is zero and Oregon’s is substantial).
QSBS Treatment: The Critical Difference for Founders
This is the single most important comparison for startup founders, and it’s not close.
Washington: QSBS gain excluded under federal Section 1202 never enters federal AGI, and therefore never enters Washington base income. A founder who sells $10 million in qualified small business stock pays $0 in Washington tax.
Oregon: Does not conform to the federal QSBS exclusion. Oregon taxes the full gain at up to 9.9%, even though the gain is excluded at the federal level. The same $10 million QSBS sale generates approximately $990,000 in Oregon tax. Oregon’s SB 1507 attempted to restore QSBS conformity but failed.
Nevada: No income tax means no state tax on QSBS gains. $0.
For a founder with significant QSBS, the difference between Oregon and Washington/Nevada can be millions of dollars on a single exit. This alone can determine where a founder chooses to establish residency. For detailed analysis, see Does QSBS Avoid Washington’s 9.9% Tax? and the 2026 QSBS State-by-State Conformity Guide.
Capital Gains
Washington: Separate capital gains tax at 7% on long-term gains from $250,000 to $1 million, and 9.9% above $1 million. Gains from direct real property sales are exempt. QSBS gains are excluded. The capital gains tax and income tax are coordinated under §302 to prevent double taxation.
Oregon: Taxes capital gains as ordinary income at rates up to 9.9%. No exemption for real estate gains, no special treatment for any gain type. Short-term and long-term gains are taxed identically.
Nevada: No capital gains tax.
For a $3 million long-term capital gain (non-QSBS, non-real estate): Washington approximately $247,000 (capital gains tax), Oregon approximately $290,000 (income tax), Nevada $0. Washington’s real estate exemption is a major advantage for property investors — Oregon taxes real estate gains at the full rate.
Business Taxes
All three states impose some form of business tax, but the structures differ significantly.
Washington B&O tax: A gross receipts tax at rates from 0.471% to 1.5%, depending on business classification. No deductions for cost of goods sold or business expenses. Applied to gross revenue, not profit. This is Washington’s primary business tax and has been in place for decades.
Oregon Corporate Activity Tax (CAT): 0.57% on gross receipts above $1 million, after subtracting 35% of cost of inputs or labor costs (whichever is greater). The CAT was enacted in 2019 and applies to all business types, including pass-throughs.
Nevada Commerce Tax: Applied to gross revenue above $4 million at rates from 0.051% to 0.331%, depending on industry. The threshold is higher and rates are lower than either Washington or Oregon.
For a software company with $10 million in gross revenue: Washington B&O approximately $14,700 (at the 0.471% retailing rate) to $150,000 (at the 1.5% service rate). Oregon CAT approximately $39,000 (after input deduction). Nevada Commerce Tax approximately $15,000–$20,000. The relative burden depends heavily on business classification and margin structure.
Estate Tax
This is an area where Washington stands out — and not in a good way.
Washington: Estate tax on estates above $2.193 million, with rates from 10% to 20%. No portability between spouses. This is one of the most aggressive estate tax regimes in the country.
Oregon: No state estate tax. Oregon repealed its estate tax in 2012.
Nevada: No state estate tax.
For a $10 million estate: Washington approximately $1.1 million in estate tax. Oregon $0. Nevada $0. For a founder with significant wealth who isn’t planning to sell and relocate, Washington’s estate tax can dwarf the income tax savings over a lifetime. This is often the deciding factor for retirees weighing Washington against Nevada.
Sales Tax
Washington: 6.5% state rate plus local additions, totaling 8.5–10.25% in most urban areas. Seattle is approximately 10.25%.
Oregon: No sales tax. This is Oregon’s signature tax advantage and a major lifestyle benefit for residents.
Nevada: 6.85% state rate plus local additions, approximately 8.375% in the Las Vegas area. Reno is approximately 8.265%.
Oregon’s zero sales tax is a meaningful quality-of-life advantage, especially for consumer purchases. Washington and Nevada have comparable sales tax burdens.
The Lifestyle Tradeoff
Taxes aren’t the only variable. Each state offers a different ecosystem for founders.
Washington (Seattle/Bellevue): Home to Amazon, Microsoft, and hundreds of startups. Deep engineering talent pool, strong venture capital presence, and proximity to other Pacific Northwest tech companies. The trade-off: higher cost of living, aggressive state tax regime (income tax + capital gains tax + B&O + estate tax), and increasingly complex compliance.
Oregon (Portland): A growing but smaller tech scene anchored by Intel, Nike, and a cluster of mid-stage startups. No sales tax, but income tax from dollar one at rates up to 9.9%. Lower cost of living than Seattle, but fewer venture capital resources and a smaller talent pool.
Nevada (Reno/Las Vegas): Reno’s tech hub is growing rapidly, with companies relocating from California and Washington. No income tax, no estate tax, low business taxes. The trade-off: a thinner talent pool (though improving), less venture capital, and a different lifestyle profile than the Pacific Northwest.
Who Should Go Where?
The right answer depends on your specific situation:
Founder with QSBS approaching an exit: Washington or Nevada. Oregon’s failure to conform to Section 1202 makes it prohibitively expensive for QSBS exits. Between Washington and Nevada, Nevada saves more — but Washington’s tech ecosystem may be worth the 9.9% tax on non-QSBS income.
High-earning employee ($500K–$999K): Washington is the clear winner. You pay zero Washington income tax, while Oregon charges $40,000+. Nevada is also zero, but Washington’s job market for tech workers is vastly larger.
Founder with $2M+ annual income, no QSBS: Nevada saves the most. Washington costs approximately $99,000, Oregon approximately $190,000, Nevada $0. But if your company and team are in Seattle, the relocation cost may exceed the tax savings.
Retiree with significant estate: Nevada strongly preferred. Washington’s estate tax (potentially $1M+ on a large estate) makes it expensive to die in Washington. Oregon has no estate tax, making it a reasonable middle ground if you prefer the Pacific Northwest.
Small business owner under $1M: Washington is best among these three — zero income tax, and B&O tax is generally manageable. Oregon taxes from dollar one. Nevada is cheapest but may lack the customer base and talent pool.
The Bottom Line
Nevada is the cheapest state on paper — no income tax, no estate tax, low business taxes. Washington protects QSBS and doesn’t tax income below $1 million, but its estate tax is punishing. Oregon taxes from dollar one, doesn’t protect QSBS, and imposes the same 9.9% top rate as Washington at a fraction of the threshold.
For most founders and investors, the decision comes down to whether the ecosystem advantages of Washington or Oregon justify the tax premium over Nevada. And for anyone holding QSBS, Oregon is the most expensive option by far.
