Washington\u2019s newly enacted income tax targeting high earners may not officially take effect until 2028, but it has already triggered a flurry of political, legal, and legislative activity across the state. A crucial date has now been set for oral arguments in an ongoing constitutional challenge that seeks to block the law before it can ever be implemented. Meanwhile, the debate over the tax’s scope has intensified, with a state lawmaker recently proposing to aggressively expand its reach by lowering the income threshold from $1 million down to $250,000. As these policy battles play out in the courts and the legislature, voters will also have their say this November through Initiative 645, a ballot measure designed to overturn the legislature\u2019s decision and permanently prevent the tax from taking effect.<\/p>\n
The road to the current legislative clash has been marked by a series of strategic political maneuvers. In 2024, the state legislature overwhelmingly approved a filed ballot measure stipulating that neither the state nor any county, city, or other local jurisdiction in Washington could tax any individual person on any form of personal income. Rather than allowing the question to go directly to the general electorate, lawmakers took matters into their own hands. This was largely a procedural move rooted in state governance rules: amending language adopted directly by a ballot measure requires a two-thirds legislative supermajority for the first two years. <\/p>\n
Had voters been allowed to approve the measure in November 2024, lawmakers would have been constitutionally barred from considering an income tax until the 2027 legislative session. By taking the measure off the ballot and passing the language themselves earlier in 2024, lawmakers effectively started the clock sooner. This allowed them to return during the 2026 session rather than waiting until 2027, enabling them to pursue legislation that did what the previous measure initially sought to prohibit: adopt a targeted income tax.<\/p>\n
In another procedural maneuver, Washington lawmakers attached an emergency clause to the high-earner income tax bill. The legislation dictates that the tax does not go into effect until 2028, with the first tax filing date scheduled for 2029, yet the emergency clause asserted that the measure was necessary for the support of the state government and its existing public institutions. This designation effectively shielded the measure from a provision in Washington law that ordinarily allows voters to review tax changes through a referendum. With that traditional avenue blocked, opponents of the income tax instead organized and filed their own initiative to repeal the law, successfully securing its placement on the upcoming November ballot as Initiative 645.<\/p>\n
The introduction of the tax represents a historic shift for Washington, which has historically lacked an individual income tax and whose constitution has long been interpreted as largely prohibiting income taxation\u2014a legal reality underlying the pending litigation. Under the new framework, some high-earning residents in Seattle could face the highest combined state and local top marginal tax rate in the entire country. When combining the new 9.9 percent state tax with the 5 percent Seattle Social Housing Tax, the 2.557 percent Seattle JumpStart Tax, and the 0.58 percent WA Cares tax, top earners in the city could confront a combined tax rate of 18.037 percent, split across employers and employees.<\/p>\n
The tax itself is structured to target individuals or married couples with annual incomes exceeding $1 million. In practice, this threshold will fall most heavily on small business owners and highly compensated technology sector workers. Because very few salaried workers earn more than $1 million annually, incomes at that level typically flow through three primary channels: capital gains and dividend income, pass-through business income, and restricted stock unit (RSU) vesting. <\/p>\n
RSU vesting can create significant tax complications for tech workers. When a private company goes public, years worth of granted stock shares can vest all at once. An individual might work at a startup for five years, and upon an initial public offering, all five years of accumulated stock vest simultaneously, yielding an income total above $1 million for that single year\u2014even though their average annual income over the multi-year employment period was well below the taxable threshold.<\/p>\n
In addition to tech workers, the tax heavily impacts pass-through businesses, which include sole proprietorships, partnerships, and S corporations. According to data from the U.S. Small Business Administration, Washington is home to 672,472 small businesses, the vast majority of which operate as pass-through entities. These businesses employ 1.4 million people, accounting for 48.4 percent of all private-sector employees in the state. Imposing a 9.9 percent tax on small business owners subjects them to one of the highest income tax rates in the nation. This burden comes on top of an existing state tax code that already imposes a high-rate gross receipts tax\u2014known as the Business & Occupation Tax\u2014while subjecting an unusually high share of everyday business inputs to the state sales tax.<\/p>\n
Washington\u2019s existing tax structure has long been heavily skewed toward business taxation, partly because the state historically avoided a broad-based individual income tax. However, unlike other states that also lack an individual income tax, Washington does not possess a low-tax, limited-government fiscal ethos. This combination forces local businesses to shoulder a disproportionate share of the overall tax burden. By superimposing a high-rate income tax specifically on high earners, critics argue that Washington has created the worst of both worlds for small business owners, constraining their capacity for expansion and undercutting local job creation.<\/p>\n
The unpredictable nature of the tax means that workers holding RSUs are not the only ones who could find themselves unexpectedly subjected to the levy. Individuals selling a family business they spent decades building, or those generating significant capital gains from the sale of a primary residence, could easily cross the $1 million threshold in a single year, triggering substantial tax liabilities.<\/p>\n
Furthermore, tax policy analysts have pointed out several unusual structural elements within the new law. The statute\u2019s charitable deduction is strictly capped at $50,000. Additionally, joint filers are subject to the tax at the exact same $1 million threshold as single filers, creating a marriage penalty where two single earners making $600,000 each would face zero tax liability, while a married couple with the same combined income would be fully taxed. <\/p>\n
The tax framework also lacks any safe harbor provisions for individuals who unexpectedly cross the threshold due to volatile income events. Under federal tax law and the systems used in most other states, underpayment penalties are waived if taxpayers pay at least 90 percent of their current year tax liability or 100 to 110 percent of their prior year liability throughout the year via withholding or quarterly estimated payments. Washington\u2019s new law contains no such safety mechanism, meaning taxpayers who misjudge their liability or fail to anticipate becoming filers could face severe administrative penalties.<\/p>\n
Repealing the new tax via the ballot box remains an uphill battle for its opponents, a challenge compounded by the wording on the ballot itself. Voters reading the measure will encounter an official fiscal impact statement warning that a repeal would require cuts to public education funding, even though the tax is not yet operational and has not generated any revenue. Under a 2022 state law, the attorney general is authorized to supply a fiscal impact statement for ballot measures. Critics of the statement attached to Initiative 645 point out that it speaks of imminent funding decreases despite the tax not yet existing and no state budget having been adopted that incorporates those future revenues. <\/p>\n
Nevertheless, as state lawmakers continue discussing proposals to expand the tax to an even broader segment of the population before it officially takes effect, many voters may lean toward a familiar precedent. Throughout the state’s modern political history, Washington voters have consistently rejected the implementation of a state income tax whenever given the opportunity at the ballot box.<\/p>\n","protected":false},"excerpt":{"rendered":"
