Wait. Does Washington actually have an income tax now?
If you’ve lived in Seattle, Spokane, or anywhere near the Sound for more than a few years, you know the "no income tax" label has been a point of pride—or a point of contention—since roughly the Great Depression. But honestly, the answer isn't a simple "no" anymore. It’s more like a "it depends on who you are and how you make your money."
Things are changing fast in 2026.
For decades, the state constitution was basically a titanium wall against taxing what you earn. But lately, lawmakers have found some clever ways to work around that wall. If you’re a high-earner or a business owner, you've probably noticed your paystub or your tax filings looking a little different. Let’s get into the weeds of what’s actually happening with the Washington state income tax situation right now.
The "Millionaire’s Tax" and the 2026 Shift
As of early 2026, the biggest story in Olympia is the push for a graduated income tax. Specifically, Governor Bob Ferguson and various Democratic leaders have been moving forward with a proposal often called the "Millionaire’s Tax."
Here is the deal: they want a 9.9% tax on individuals earning more than $1 million a year.
Now, if you’re thinking, "Wait, didn't voters just pass Initiative 2111 in 2024 to ban this?" you’re right. They did. But in politics, a "permanent ban" is often just a speed bump. Lawmakers are currently debating how to navigate that initiative while also eyeing the potential for a constitutional amendment.
The interesting part? Even if this passes the 2026 legislative session, you won't see it on your 2026 return. The current plan wouldn't actually start collecting revenue until 2029. It’s a long game. They’re basically setting the stage for a massive legal showdown in the State Supreme Court.
Why this matters to you (even if you aren't a millionaire)
Opponents, like State Senator John Braun, argue that once the door is cracked for a tax on the wealthy, it eventually swings open for everyone. Historically, that's how these things go in other states. Plus, Washington isn't looking to trade. There’s no talk of getting rid of the sales tax in exchange for an income tax. You’d just be paying both.
The Capital Gains Tax: The Income Tax That "Isn't"
If you want to understand why people are confused about the Washington state income tax, look no further than the Capital Gains Tax.
The IRS says capital gains are income. Almost every other state says they’re income. But the Washington State Supreme Court? They called it an "excise tax."
By labeling it an excise tax—a tax on the privilege of selling something—they bypassed the constitutional ban on taxing income. It’s a bit of legal gymnastics, but it worked.
Starting with the 2025 tax year (returns due in April 2026), the rates have actually gotten more complex:
- 7% tax on the first $1 million of taxable capital gains.
- 9.9% tax on anything above that $1 million mark.
The threshold used to be $250,000, but the new tiered system is a significant shift. If you sold a big chunk of stock or a business recently, you’re likely already feeling the effects of what is, for all intents and purposes, a limited Washington state income tax.
Your Paystub is Already Leaking: WA Cares and Paid Leave
Most people think of "income tax" as one big chunk taken by the Dept. of Revenue. In Washington, it’s death by a thousand papercuts. Your paycheck is already being hit by mandatory premiums that feel exactly like a tax.
Take the WA Cares Fund. This is the state’s long-term care insurance program.
As of 2026, the benefit rollout is finally happening. If you’re a worker in Washington, you’re paying 0.58% of your gross wages into this fund. There is no cap. If you make $50,000, you pay $290 a year. If you make $500,000, you pay $2,900.
Then there’s the Paid Family and Medical Leave (PFML).
Rates just jumped again. Starting January 1, 2026, the total premium rate is 1.13% of your wages (up from 0.92% last year). Employees foot about 71% of that bill. While these are technically "premiums" for "social insurance," when the money leaves your check based on your earnings, most people call that an income tax.
The Business and Occupation (B&O) Factor
If you run a business, you know Washington’s tax code is a bit of a nightmare. Instead of taxing your profits (net income), the state taxes your gross receipts.
This is the B&O tax.
Starting January 1, 2026, a new 0.5% surcharge kicked in for businesses with Washington taxable income over $250 million. Also, if you’re in "advanced computing," your surcharge just skyrocketed from 1.22% to 7.5%.
For the small business owner, the "service and other" rate is now 2.1% for those with gross income over $5 million. It’s getting expensive to do business here, and those costs almost always trickle down to the consumer or the employees' potential raises.
What Most People Miss: The Sales Tax Burden
While we argue about a Washington state income tax, we often ignore the fact that Washington has one of the highest sales tax burdens in the country.
The state rate is 6.5%, but once you add local taxes, you’re looking at 9% to 10.5% in places like Seattle or Lynnwood.
This is why the Tax Foundation often ranks Washington’s tax system as one of the most "regressive" or "upside-down." Lower-income families pay a much higher percentage of their earnings in taxes because they spend a larger chunk of their check on taxable goods. To counter this, the state expanded the Working Families Tax Credit, which basically acts as a sales tax refund for eligible households.
Actionable Steps for 2026
The landscape is shifting. You can't just assume your tax bill is "zero" because there’s no traditional 1040-style state return.
1. Audit your paystub immediately. With the PFML rate hike to 1.13% and the WA Cares 0.58% deduction, you’re losing nearly 2% of your gross pay to state mandates before you even pay federal taxes. Ensure your employer is using the 2026 Social Security wage cap of $184,500 for PFML—anything earned above that shouldn't be taxed for that specific program.
2. Watch the "Millionaire Tax" litigation. If you fall into the high-income bracket, talk to a tax professional about "income shifting" or "domicile" strategies. The state is becoming much more aggressive about identifying who is a Washington resident for tax purposes, especially with the capital gains tax.
3. Check your Capital Gains exemptions. The capital gains tax has some massive loopholes. Real estate sales, retirement accounts (401ks/IRAs), and certain family-owned small businesses are exempt. If you're planning a major asset sale in 2026, structure it to fit these exemptions.
4. Claim your credits. If you’re a lower-to-middle-income household, make sure you apply for the Working Families Tax Credit. It can provide up to $1,200+ depending on your family size. Many people leave this money on the table because they think they don't have to file anything with the state.
5. Plan for the WA Cares pilot. If you live in Lewis, Mason, Spokane, or Thurston counties, you might be eligible for the benefit pilot program that started this month (January 2026). If you need long-term care now, this is your first chance to see if that 0.58% you’ve been paying was actually worth it.
The "no income tax" era in Washington isn't over, but it’s definitely in the rearview mirror for a growing number of residents. Whether it’s called a premium, a surcharge, or an excise tax, the reality is that the state is finding ways to tax what you earn.
