How to Oppose Washington’s SB 6346: A Practical Guide to Stopping the “Millionaire Tax” Before It Grows

As Washington’s 2026 legislative session moves forward, one proposal is drawing significant attention: SB 6346, commonly described as a new “millionaire tax.”

Supporters call it targeted taxation. Opponents see something different — the possible expansion of state income taxation in a state where voters have repeatedly rejected it.

If you’re concerned about higher taxes, economic competitiveness, or the long-term impact on Washington families and businesses, here’s a clear, step-by-step guide to making your voice heard.

The STEPS you can take are further in the article.

Sen. Nikki Torres shares the devastating economic impact the income tax will have on small businesses in our state (SB 6346).

Let’s Go Washington on Facebook:


What Is SB 6346 — And Why Are People Concerned?

SB 6346 proposes a new tax structure aimed at high-income earners. Critics argue that while it is framed as affecting only the wealthy today, tax thresholds have a history of shifting over time.

Common concerns raised by opponents include:

  • It represents a form of state income tax.
  • Washington voters have historically rejected income tax proposals.
  • The $1 million threshold could be lowered in future legislative sessions.
  • It may reduce Washington’s economic competitiveness.
  • Small business owners with pass-through income could be affected.

For many residents, the issue isn’t just about today’s tax bracket — it’s about what comes next.


How to Oppose SB 6346 in Washington State

If you want to stop SB 6346, action during the legislative session (February–March 2026) is critical. Here are the most effective steps.


1. Officially Sign In “CON” (Opposed)

The single most important action you can take is to register your opposition in the legislative record.

Through the Washington State Legislature website, citizens can:

  • Sign in “CON” (opposed) for committee hearings
  • Submit written testimony
  • Register to testify remotely or in person

Thousands of Washington residents have already used this tool. Lawmakers track how many people sign in for and against a bill — and those numbers matter.

👉 Visit: https://app.leg.wa.gov/csi/House
Find the hearing for SB 6346 and select “Sign in to testify” or “Submit Written Testimony.”

Even if you don’t speak publicly, signing in registers your opposition permanently in the public record.


2. Call the Legislative Hotline

Direct communication still works.

📞 1-800-562-6000

When you call:

  • Provide your name and address (to confirm your district)
  • Clearly state you are “CON” on SB 6346

Short, respectful calls can influence undecided legislators — especially when many citizens speak up.


3. Email Your State Representative and Senator

Through the Washington State Legislature website, you can send emails directly to your district lawmakers.

Suggested Talking Points:

  • Washington voters have repeatedly rejected state income taxes.
  • This may be a “millionaire tax” today, but thresholds can change.
  • Higher taxes could drive investment and job creators out of state.
  • Washington should focus on spending reform before adding new taxes.

Keep your message clear, concise, and civil.


4. Testify at a Public Hearing

SB 6346 is currently being reviewed in the House Finance Committee.

You can testify:

  • Remotely (via Zoom)
  • In person in Olympia

Even 1–2 minutes of testimony can have an impact, especially when many residents show up. Lawmakers notice participation levels.


Who Is Leading the Opposition?

Several organizations and business groups are actively working to stop SB 6346.

Let’s Go Washington

Led by Brian Heywood, this organization has mobilized residents to sign in against the measure during hearings. They report more than 100,000 individuals have registered opposition.

National Federation of Independent Business (NFIB)

reports that 98% of participating members oppose the proposal. The organization argues the tax could harm pass-through businesses and discourage growth.

Major Business Coalitions Opposing SB 6346

A joint opposition statement has been issued by:

  • Washington Roundtable
  • Association of Washington Business
  • Bellevue Chamber of Commerce
  • Seattle Metropolitan Chamber of Commerce
  • Greater Spokane Inc.

Washington Policy Center

This think tank has also published a petition opposing a state income tax in Washington.


5. Contact the Governor

Governor Bob Ferguson has expressed support for a millionaire tax approach.

You can contact his office:

📞 360-902-4111

When calling:

  • State your name and city
  • Clearly express opposition to SB 6346

Governors pay attention to volume. If enough constituents call, it sends a message.


Why Tax Policy Expansions Matter

Across the country, tax policy often begins narrowly and expands over time. Opponents argue that once an income-style tax structure is in place, adjustments become easier in future sessions.

For critics, this debate is about more than a single bill. It’s about:

  • Protecting Washington’s no-income-tax tradition
  • Preventing gradual tax bracket expansion
  • Preserving small business flexibility
  • Maintaining economic competitiveness

Taxes introduced “for the wealthy” can evolve — and history shows that thresholds rarely stay fixed forever.


Take Action Before It’s Too Late

The 2026 legislative session is active right now. Committee votes can move quickly.

If you oppose SB 6346:

  • ✔ Sign in “CON”
  • ✔ Call the hotline
  • ✔ Email your legislators
  • ✔ Testify at hearings
  • ✔ Support advocacy groups
  • ✔ Contact the Governor

Civic engagement is most effective before the vote happens — not after.

If Washington residents who are concerned about tax growth stay silent, the policy will move forward without resistance.
