Washington's Shifting Landscape
for Business Owners
At a glance
Three numbers that changed the math.
Capital gains tax begins
- Washington's first-ever tax on long-term capital gains: 7% above an annual deduction ($250,000 at launch, adjusted for inflation each year)
- Applies to gains on stocks and business interests - real estate is exempt
Pay transparency & a new payroll tax
- Pay transparency (Jan): employers with 15+ must post a salary range in every job listing - later rulings raised the litigation risk
- WA Cares (July): a 0.58% payroll tax on all wages, no cap, for long-term care
The largest tax package in state history
- Capital gains: a 2.9% surcharge on gains over $1M - top rate now 9.9% (retroactive to Jan 1, 2025)
- Estate tax: exemption raised to $3M, top rate spiked to 35% - highest in the nation
- B&O tax: service businesses over $5M rise 1.75% → 2.1%; broad increases phased in
- Sales tax expanded to services: IT, advertising, software, staffing, security, live presentations
Payroll and wage costs keep climbing
- Paid Family & Medical Leave: 0.74% → 0.92% → 1.13% (2024-2026)
- Minimum wage: $16.66 → $17.13 (2026) - highest in the nation
- Overtime-exempt salary floor: now $80,168/yr, heading toward $93,392 by 2028
Washington bans nearly all non-competes
- Non-compete agreements become void for virtually all Washington workers - regardless of pay
- Employers must notify current and former workers that existing non-competes are void
- Also limits non-solicitation and clawback/forfeiture provisions
The estate tax rollback
- After taxpayer pushback, the 35% top estate-tax rate was rolled back to 20%
- The exemption stays at $3M and no longer adjusts for inflation
More workplace mandates arrive
- Pregnancy and postpartum accommodation expands to all employers, regardless of size
- Further limits on background checks and hiring practices
The "millionaires' tax" arrives
- A 9.9% tax on household income above $1M/year - Washington's first broad income tax
- Applies to residents and non-residents with Washington-source income
- First returns due 2029; Initiative 645, on the November 3, 2026 ballot, would repeal it, and a court challenge is pending
Some 2025 changes scheduled to unwind
- The 2025 sales-tax-on-services expansion is set to be repealed (except advertising)
- The temporary B&O surcharge on the largest companies is set to expire
What does this mean for you?
Taxes are only half of it. Between the tax changes and the new rules on pay, leave, and non-competes, the ground under a Washington business owner keeps shifting, and each change lands differently depending on the size of the business, the plan for an eventual sale, and how much wealth sits inside the company versus outside it.
The owners who come through these shifts well are the ones who saw them coming. If any of this raises a question about your own situation, that is exactly the kind of thing worth talking through.
