Washington’s New Income Tax Changes Everything

Washington passed Senate Bill 6346 in early 2026. It is often called the Millionaire’s Tax.
The law creates a 9.9% tax on income over $1 million and is scheduled to begin in 2028.
It has drawn attention for two main reasons:

• It creates a new income tax structure in Washington
• It includes an emergency clause, which blocks a referendum and keeps voters from weighing in directly

That second point matters in a state where voters have rejected income tax proposals many times.

This article covers:

• How the tax works
• Who pays it
• Why the emergency clause matters
• How it fits into Washington’s broader tax direction
• What it could mean for business, migration, and Clark County real estate

How Washington’s new income tax works, and who pays it

SB 6346 applies to high earners only.

Key facts:

• Tax rate: 9.9%
• Applies to: income above $1 million
• Income under $1 million: not taxed under this bill
• Estimated people affected: about 30,000
• Projected annual revenue: about $3.7 billion

State leaders say the money would help fund:

• health care
• child care
• higher education
• other public services

For most households, this tax will not create a direct cost.
Still, the bill has received broad attention because:

• it introduces a state income tax structure
• it raises questions about future tax policy
• Washington has long been seen as a no-state-income-tax state

A simple example of what the 9.9% tax could look like

If a household earns $2 million in one year:

• The first $1 million is not taxed under this law
• The second $1 million is taxed at 9.9%
• That adds $99,000 in tax

The tax applies only to income above the threshold.
It does not apply to the full amount earned.

Why the emergency clause is a big part of the debate

The emergency clause is one of the most disputed parts of the law.
In practical terms, it does this:

• Let the law take effect without a referendum
• prevents voters from sending it to the ballot

That has become a major issue in Washington because the state has a long history of rejecting income tax proposals.
For many residents, this is not only about tax policy. It is also about process.

The main concern is simple:

• lawmakers approved a major tax change
• voters will likely not get a chance to approve or reject it

Supporters of emergency clauses usually argue that some laws should take effect without delay.
Critics argue this clause does something different:

• blocks public review
• avoids a statewide vote
• removes a check voters have used in the past

Another issue was added to the concern.
During the debate, lawmakers rejected an amendment that would have barred future expansion of the tax to lower income brackets.
That did not change the current law. The threshold remains above $1 million.
But the failed amendment raised a larger concern:

• The bill does not permanently protect lower-income brackets
• A future legislature could revisit the threshold

Why are people worried it could reach lower-income brackets later

The law does not tax lower earners today.
That part is clear.
The concern is what could happen later.

Reasons people are watching this closely:

• The bill does not contain permanent limits on future expansion
• An amendment meant to add those limits failed
• That leaves the issue open for future lawmakers

That does not mean the tax will expand.
It does mean the bill does not prevent it.
For critics, that creates future policy risk.
For supporters, it leaves room for future legislative action.

Washington’s bigger tax trend helps explain the reaction

Many residents and business owners are not looking at SB 6346 on its own.
They see it as part of a broader change in Washington’s tax climate.
Over the last few years, people have already had to track:

• new payroll taxes
• rising leave-related costs
• changes to business taxes
• added taxes on capital gains and fuel

That larger pattern shapes how this law is being received.
Even people who will never pay this tax may still see it as part of a bigger shift in state policy.

Business owners, in particular, tend to look at the total cost picture, including:

• payroll costs
• business taxes
• transportation costs
• investment taxes
• future tax direction

The taxes business owners and workers are already watching

• WA Cares payroll tax: a payroll deduction tied to the state’s long-term care program
• B&O tax changes: affects gross receipts, not just profit
• Paid family and medical leave: payroll costs have increased over time
• Capital gains tax: added a new layer to the state’s tax system
• Gas tax increases: raise commuting and delivery costs
• Luxury vehicle tax: adds cost to certain high-priced vehicle purchases

Taken together, these taxes help explain why SB 6346 is getting so much attention.

What this could mean for businesses, migration, and Clark County housing

Tax policy can affect behavior over time.
One concern is tax flight, which means some high earners or business owners may choose to move to lower-tax states.
That does not happen in every case.
People often stay because of:

• family
• work
• schools
• business ties
• quality of life

Still, taxes can influence decisions at the margin, especially for people with flexible income, investment income, or the ability to relocate.
For Clark County, that matters more than in many other parts of Washington.
The area has long benefited from its position near Oregon.
Many buyers have chosen places like:

• Vancouver
• Camas
• other parts of Clark County

One reason is clear:

• They can live in Washington
• Stay connected to the Portland metro area
• avoid Oregon’s state income tax

If Washington’s no-income-tax advantage starts to look less secure, that could affect:

• buyer demand
• relocation decisions
• business confidence
• local housing activity

Large employers may watch this too.
When companies choose where to expand, they often compare:

• taxes
• labor costs
• land
• regulation
• long-term operating costs

Small and mid-sized business owners may feel pressure as well.
In many cases:

• Business income and personal income are closely connected
• Tax changes can affect hiring and investment decisions
• owners may reconsider where they live or grow

Why Clark County has more at stake than many other parts of Washington

Clark County is in a different position than most of the state because of the Oregon border.
For many households, the appeal has been simple:

• live in Washington
• work in the Portland area
• avoid a state income tax

This law does not change that for most people today.
As written, it only applies to income above $1 million.
But the larger local concern is about direction, not just the current threshold.

Key questions include:

• Is Washington starting to move away from its no-income-tax identity?
• Will buyers and investors see that advantage as less stable?
• Could Clark County feel that change faster than other parts of the state?

Those questions matter for homeowners, buyers, investors, and local businesses.

Conclusion

Washington has now passed SB 6346, creating a 9.9% tax on income above $1 million, with a planned start date of 2028. The tax itself is a major policy shift, but the emergency clause has made the law even more controversial because it blocks voters from challenging it through a referendum. What happens next is still uncertain. Legal challenges are likely, future lawmakers could try to change the threshold, and the market response may take time to unfold. For people in Washington, especially in Clark County, the bigger issue is not only this law as written today, but what it may signal about the state’s tax direction going forward.
