Washington's NEW Income Tax Just Passed: What SB 6346 Means for Vancouver WA Residents

To understand why this happened, you have to understand Washington's budget problem — because it's been building for years. Washington's state budget has roughly doubled since 2015. State spending has grown significantly faster than population growth and inflation combined. Every two-year budget cycle, lawmakers have been staring at projections showing a larger and larger shortfall.

In 2025, Governor Ferguson signed what was described as the largest tax increase in Washington State history — a package that raised the B&O tax on service businesses, expanded the sales tax to new service categories, increased the gas tax, overhauled the estate tax, and made the capital gains tax progressive. That package was designed to close a $15 to $16 billion projected shortfall.

And it still wasn't enough.

Going into the 2026 legislative session, the state was already looking at another multi-billion dollar budget gap in the 2027–2029 cycle. The legislature made a decision that shocked even seasoned Olympia observers: they wrote the expected revenue from a not-yet-passed income tax directly into the budget. They spent the money before the law existed. Without the income tax, the Senate budget would have shown a negative $3 billion balance in the next biennium.

That's the context. This wasn't a casual policy preference. This was a legislature that felt it had run out of other options — and chose to cross a line that Washington's political culture had treated as uncrossable for 90 years.

There's a lot of misinformation floating around. Let's go through the mechanics carefully.

The tax imposes a 9.9% rate on all household income above $1 million per year. Only the amount above $1 million is taxed. If your household earns $1.1 million, you owe 9.9% on $100,000 — that's $9,900. You owe nothing on the first million.

The threshold is per household, not per person. A married couple where both spouses each earn $600,000 has combined income of $1.2 million — they'd owe tax on $200,000 above the threshold. And the 9.9% rate is not coincidentally the same as Oregon's top income tax rate. For the first time ever, high earners in both states face the same top state income tax rate.

This is where the business community's alarm is most acute. The bill taxes "household income" — broadly defined to include wages, salaries, business income, and critically: restricted stock units (RSUs). RSUs are a primary form of compensation for tech workers across the Pacific Northwest. The Tax Foundation analyzed this and found that for a tech employee receiving a significant RSU grant in a single year — pushing total compensation over $1 million — the effective combined state tax burden on that compensation could exceed 18%. That affects hundreds of tech workers in the Seattle–Bellevue corridor every year.

Effective date: January 1, 2028 — the tax begins applying to income earned from that date forward. First payments: 2029 — that's when the first tax returns and payments will be due. If the law is struck down or repealed before 2028, no tax is ever collected. There is a legal and political window.

The reaction has been extraordinary — not performative political noise, but genuine, sustained, cross-partisan opposition.

The House debate ran for 25 straight hours. Lawmakers slept in their offices in one-hour shifts, rotating back to the floor to vote on amendments. Over 100 amendments were proposed — every single one failed on party-line votes. The final House tally: 51 to 46. Not a single Republican voted yes. Eight Democrats voted no. One of the closest and most contentious votes in recent Washington legislative history.

When SB 6346 had its first public committee hearing, more than 61,000 people signed in to oppose it — an almost unprecedented number for a state legislative hearing. Protesters showed up outside the State Capitol. Phone lines to legislators were jammed for days.

Tech executives began publicly discussing relocation of operations or future hiring to Nevada, Texas, or Florida — all zero-income-tax states actively trying to poach Washington businesses. The Tax Foundation warned the bill could prove a tipping point for Washington's status as a tech hub. House Republican Leader Drew Stokesbary put it plainly: "While the title says this is a tax on millionaires — I believe this is a tax on Washingtonians. It just matters when it's going to apply to which Washingtonian." That's the core long-term concern: income taxes introduced as taxes only on the wealthy have a long track record of expanding over time.

This is what makes SB 6346 genuinely different from most new tax laws. There is a serious, well-grounded legal argument that it is unconstitutional — and that argument was around before the bill even passed.

Washington's constitution has been interpreted — consistently, for nearly a century — to require that income taxes be uniform, meaning the same rate for everyone regardless of earnings. A graduated income tax that only taxes people above $1 million is, by definition, not uniform. In 1933, the Washington Supreme Court struck down a graduated income tax on exactly these grounds. That ruling has never been overturned.

The legislature's legal team structured SB 6346 carefully, arguing it's actually an excise tax on the privilege of earning income above a threshold — not an income tax in the constitutional sense. It's a contested argument. Governor Ferguson himself acknowledged he would not sign the bill if he believed courts were likely to strike it down — notably stopping short of calling it constitutionally bulletproof.

There's a second legal obstacle that's even more direct. In November 2024, Washington voters passed Initiative 2111 by a wide margin — explicitly prohibiting the state, counties, cities, or any other taxing authority from imposing a personal income tax in Washington. The legislature passed SB 6346 anyway, including language attempting to argue the bill supersedes I-2111. Legal experts are skeptical. Republican attorneys general and outside legal groups have already announced challenges.

Even if the courts don't act quickly enough, there's a parallel track: the citizen referendum. Under Washington law, citizens can gather signatures to place a referendum on the ballot, allowing voters to repeal a recently passed law.

Here's the catch. The legislature passed SB 6346 with an emergency clause — which doubles the normal signature threshold. To force a referendum, opponents need to gather more than 300,000 valid signatures within 90 days of the bill being signed.

That is a high bar. But Washington opposition signature campaigns have cleared 300,000 before. Multiple organizations — including the Washington Policy Center, state Republican party apparatus, and business groups — have already announced they intend to pursue the referendum path. And Washington voters have rejected income tax proposals ten times in the state's history. A referendum is not a guaranteed win for the income tax.

The law does not directly touch you. Your paycheck, retirement distributions, and investment income below $1 million remain untaxed at the state level under SB 6346 as written. But here's what matters: Washington voters were told for years there would be no capital gains tax. Then there was. They were told for 90 years there would be no income tax. Now there is. The precedent has been broken. Not the rate — the precedent. If you're buying a home, building a career, or planning to live here for 20 years — you are now in a state with income tax infrastructure. Where that goes over the coming decades is a legitimate question to factor into long-term planning.

This directly affects you starting in 2028 — unless it's struck down or repealed. Meet with a CPA and a tax attorney now, not in 2027. Key areas to review:

Understand how your RSU vesting schedule interacts with this law. If you have large vesting events scheduled for 2028 or beyond that push total compensation over $1 million, explore whether accelerating vesting before 2028 is possible and advisable. Talk to your company's equity team and a tax attorney — this is time-sensitive.

Map out your B&O tax picture against the potential income tax exposure. The credits built into SB 6346 mean you won't necessarily be double-taxed — but the interaction between B&O and the new income tax is complex enough that a professional analysis is worth every dollar.

This is where I can speak from direct experience — because this is exactly the conversation I'm having with clients right now.

For most people considering moving to Vancouver, WA, the primary tax motivation has always been the absence of Washington's income tax versus Oregon's 9.9% top rate. That gap, for high earners, was worth tens of thousands of dollars annually — and it drove a steady stream of Oregon residents across the river into Clark County.

Washington's tax identity has fundamentally shifted. It is still — for most earners — a better tax environment than Oregon. The gap has narrowed. The trend line is clear. And the future is genuinely uncertain. But for the vast majority of people moving to Vancouver, WA — families relocating for quality of life, space, and affordability; retirees retiring in Vancouver, WA; people simply wanting a home in the Pacific Northwest — none of this changes the calculus meaningfully. You still don't pay Oregon income tax. You still get Vancouver's lower cost of living, no state income tax on your W-2 wages, and one of the best community environments in the Pacific Northwest.

If you're a high-earning tech professional, business owner, or retiree drawing significant investment income that would push you over $1 million — this warrants a serious conversation with a financial planner before you buy. Not because Vancouver is no longer a great choice, but because the math just changed and you deserve to make your decision with complete information. I can connect you with local CPAs and tax attorneys who understand the Washington–Oregon tax landscape. Reach out here.

Vancouver, WA is still an outstanding place to live. The Vancouver housing market remains strong, the community is vibrant, the schools are excellent, and the proximity to Portland gives you world-class amenities without Oregon's tax burden — for the overwhelming majority of earners. If you're thinking about buying a home in Vancouver, WA, don't let this single legislative development — which is still being challenged in court — derail a decision that makes sense on every other level.

What I always tell my clients: make your real estate decision based on the full picture — lifestyle, community, affordability, schools, and yes, taxes. On almost every dimension, moving to Vancouver, Washington remains one of the smartest moves you can make in the Pacific Northwest.

Washington just passed its first income tax in 90 years. The governor is signing it. Thousands of people are furious. Legal challenges are being filed. A referendum signature campaign is underway. And nobody — not the governor, not the legislature, not legal scholars — can tell you with certainty whether this law will still be on the books in 2028 when it's supposed to take effect.
