Washington, Oregon, and Nevada sit within a few hours of each other, share overlapping tech ecosystems, and tax founders in fundamentally different ways. For anyone choosing where to base operations or establish residency, the differences are dramatic — and 2026 made them sharper, with Washington's new income tax arriving and Oregon turning hostile to the one thing founders care most about: QSBS.
(For an overview of ESSB 6346, see Washington's New Income Tax. For the full landscape, see Washington State Taxes. For the California comparison, see Washington vs. California.)
TL;DR
- Nevada is the cheapest on every dimension — no income tax, no capital gains tax, no estate tax, low business taxes.
- Washington is best for founders with QSBS (zero state tax on qualifying exits, the only West Coast state where the federal exclusion still carries through) and for anyone earning under $1M (no income tax below that). Its weak spot is the estate tax.
- Oregon is the most expensive option for most founders. It taxes from the first dollar, decoupled from QSBS in 2026 (taxing federally excluded gains at up to 9.9%), and — the part most people get wrong — has the lowest estate-tax threshold in the country at $1M.
- For high earners without QSBS: Nevada > Washington > Oregon at every income level.

Income Tax: The Headline Comparison
Washington: 9.9% on household income above $1 million, effective 2028; 0% below. The $1 million standard deduction means most residents pay nothing.
Oregon: Progressive brackets from 4.75% to 9.9%, with the top rate hitting at just $125,000 (single) / $250,000 (joint). Oregon taxes from the first dollar — there is no zero bracket for high earners. And in the Portland metro area, the Metro Supportive Housing tax (1%) plus the Multnomah County Preschool for All tax (1.5% above $125,000, rising to 3% above $250,000) add up to 4 points for high earners — pushing the effective top marginal rate to roughly 13.9% for Portland founders.
Nevada: No income tax. Zero on all income, at any level.
At $500,000: Washington $0, Oregon ~$42,000, Nevada $0. At $2M: Washington $99,000, Oregon ~$190,000, Nevada $0. At $5M: Washington $396,000, Oregon ~$485,000, Nevada $0. Nevada is cheapest at every level; Washington beats Oregon at every level and is dramatically cheaper below $1M, where Washington is zero and Oregon is substantial.
QSBS: The Difference That Can Cost Millions
This is the single most important comparison for founders, and as of 2026 it's not close.
Washington conforms to the federal §1202 exclusion. Gain excluded federally never enters federal AGI, so it never enters Washington's tax base. A founder who sells $10M of qualifying stock pays $0 in Washington.
Oregon decoupled from §1202 in 2026. Senate Bill 1507 — signed by Governor Kotek on April 9, 2026 and effective for sales on or after January 1, 2026 — requires Oregon taxpayers to add back federally excluded QSBS gain. Oregon now taxes that gain at up to 9.9%. The same $10M exit generates roughly $990,000 in Oregon tax on gain that is completely free at the federal level. (Kotek's signing letter flagged the competitiveness hit, and a referendum effort is underway — but as of today it is law.)
Nevada: No income tax, so no tax on QSBS gain. $0.
Washington is now the only West Coast state where the federal QSBS exclusion still carries through to the state level. For a founder with significant QSBS, that single fact can decide where to establish residency. (See Does QSBS Avoid Washington's 9.9% Tax? and the 2026 QSBS State-by-State Conformity Guide.)
Capital Gains
Washington: A separate capital gains excise tax — 7% on long-term gain from roughly $278,000 (the 2025 standard deduction, indexed annually) up to $1M, and 9.9% above $1M. Gains from direct real estate sales are exempt; QSBS is excluded. Beginning in 2028, §302 folds Washington-taxed capital gains into the income tax base and §205 credits the capital gains tax already paid, so the same gain isn't taxed twice.
Oregon: Taxes capital gains as ordinary income at up to 9.9% — no real estate exemption, no preferential rate, short-term and long-term treated alike.
Nevada: None.
For a $3M long-term gain (non-QSBS, non-real-estate): Washington $240,000, Oregon ~$290,000, Nevada $0. Washington's real estate exemption is a real edge for property investors; Oregon taxes real estate gain at the full rate.
The Relocation Trap: Moving Doesn't Protect the Sale
Here is the mistake that costs founders the most, and it cuts across all three states. Relocating protects your ongoing income going forward. It does not automatically protect the sale itself.
A stock sale is allocated by your domicile on the closing date — not by a day-count residency test. Clearing Washington's 30-day safe harbor, or California's safe harbor, or simply "spending most of the year in Nevada," means nothing for the gain if your domicile hasn't genuinely changed before the deal closes. The safe harbor makes you a nonresident; it does not change your domicile, and the capital gains tax follows domicile. (See Why Your Stock Sale Doesn't Care About the Safe Harbor and Washington vs. California: Safe Harbors Compared.)
The practical rule for a founder planning to move and sell: the domicile change has to be real and complete before closing. A half-measure leaves the gain taxable in Washington even if you've technically left for the year.
Business Taxes
All three states tax business activity, but the structures differ.
Washington B&O: A gross-receipts tax with no deduction for costs — applied to revenue, not profit. Rates run 0.471%–2.1% by classification; HB 2081 (2025) made the service rate tiered, topping out at 2.1% for businesses over $5M in gross income.
Oregon CAT: 0.57% on gross receipts above $1M, after subtracting 35% of input or labor costs. Applies to all entity types, including pass-throughs.
Nevada Commerce Tax: 0.051%–0.331% on gross revenue above $4M, by industry. Higher threshold, lower rates than either neighbor.
Nevada Modified Business Tax (MBT): A quarterly payroll tax — 1.17% on wages above $50,000 per quarter for general businesses (1.554% on all wages, with no exemption, for financial institutions and mining), in effect since July 2023. The $50,000-per-quarter exemption means early-stage startups with modest payroll often owe little or nothing, and half of any Commerce Tax paid can be credited against the MBT.
For a software company with $10M in gross revenue: Washington B&O ~$47,100 (0.471% retailing) to ~$210,000 (2.1% service); Oregon CAT ~$39,000 after the input deduction; Nevada Commerce Tax ~$15,000–$20,000. The real burden depends heavily on classification and margins.
Estate Tax: Where the Conventional Wisdom Is Wrong
People assume the no-sales-tax, "tax-friendly" reputation extends to estates. For Oregon, the opposite is true.
Washington: Estate tax on estates above ~$3 million ($3,076,000 for deaths from January 1 through June 30, 2026; $3,000,000 flat on or after July 1, 2026). Rates run graduated 10%–35% for deaths through June 30, 2026, then roll back to 10%–20% on July 1, 2026 under ESB 6347 — no spousal portability. Aggressive, but the $3M threshold exempts most middle-class estates.
Oregon: Estate tax on estates above just $1 million — the lowest threshold in the United States — graduated 10%–16%, not indexed for inflation, no portability. A paid-off Portland home plus a retirement account routinely crosses it. (A 2026 bill, SB 1511, to raise the threshold to $2.5M passed the Senate but did not become law; the $1M figure stands.)
Nevada: No estate tax.
For a $2M estate: Washington $0 (under the $3M exclusion), Oregon ~$100,000, Nevada $0. For a $10M estate (at the rates in effect on or after July 1, 2026): Washington ~$1.1M, Oregon ~$1.0M, Nevada $0. So Oregon is far worse than Washington for modest and mid-sized estates, and comparable for large ones. Nevada wins outright. For anyone weighing where to retire — not just where to exit — this often outweighs the income-tax comparison.
Sales Tax
Washington: 6.5% state plus local, totaling 8.5%–10.25% (Seattle ~10.25%). Oregon: None — its signature advantage. Nevada: 6.85% state plus local, ~8.375% in Las Vegas, ~8.265% in Reno. Oregon's zero sales tax is a genuine lifestyle benefit; Washington and Nevada are comparable.
The Lifestyle Tradeoff
Washington (Seattle/Bellevue): Amazon, Microsoft, deep engineering talent, strong VC presence. Trade-off: high cost of living and a stacked tax regime (income + capital gains + B&O + estate).
Oregon (Portland): A smaller scene anchored by Intel and Nike. No sales tax, lower cost of living than Seattle — but income tax from dollar one (plus Portland's local taxes), no QSBS conformity, and the country's lowest estate-tax threshold.
Nevada (Reno/Las Vegas): A fast-growing hub drawing companies from California and Washington. No income, estate, or meaningful capital gains tax. Trade-off: a thinner (but improving) talent pool and less local VC.
Who Should Go Where?
Founder with QSBS approaching an exit: Washington or Nevada. Oregon's 2026 decoupling makes it the worst possible state for a QSBS exit. Both states tax the QSBS gain at $0, so the exit itself is a tie; Nevada wins on everything after it — ongoing income, future gains, and estate tax. Stay in Washington only if the operating ecosystem is worth it on its own terms.
High-earning employee ($500K–$999K): Washington wins clearly — $0 state income tax versus $40,000+ in Oregon — and the tech job market dwarfs Nevada's.
Founder with $2M+ income, no QSBS: Nevada saves the most ($99K Washington / ~$190K Oregon / $0 Nevada). But if your company and team are in Seattle, relocation costs may exceed the savings.
Retiree with a significant estate: Nevada, decisively. The surprise is that Oregon is the worst of the three, not a middle ground — its $1M estate threshold catches estates Washington exempts entirely. Anyone choosing the Pacific Northwest for retirement should plan for Oregon's estate tax, not assume it away.
Small business owner under $1M: Washington is best of the three — $0 income tax and manageable B&O. Oregon taxes from dollar one; Nevada is cheapest but may lack the customer base and talent.
The Bottom Line
Nevada is the cheapest on paper — no income, estate, or capital gains tax. Washington protects QSBS, exempts income below $1M, and is now the only West Coast state where the federal QSBS exclusion sticks — but its estate tax bites above $3M. Oregon taxes from the first dollar, decoupled from QSBS in 2026, and has the lowest estate-tax threshold in the country. For most founders the question is whether Washington's operating ecosystem is worth staying for on its own terms; the tax math favors Nevada — and for anyone holding QSBS, Oregon is the most expensive option by a wide margin.
And whichever way you lean: if a liquidity event is in the picture, the move has to be genuine and complete before the sale closes, or the gain stays taxable where you started.
