The specter of capital flight, an economic phenomenon where wealth and investments move out of a jurisdiction due to increased taxation or unfavorable business conditions, has become a central point of contention in Washington State. At the heart of this debate is a proposed 9.9% income tax on households earning over $1 million annually, a measure championed by Washington Democrats and currently on its way to the governor’s desk. While proponents largely dismiss predictions of wealthy individuals fleeing the state, critics argue that such a tax would inevitably lead to a significant exodus of capital, impacting the state’s economy and philanthropic landscape.
Background: A State Divided on Taxation
Washington State has long been an outlier among its peers, notably for not having a state income tax. This has been a significant draw for businesses and high-net-worth individuals alike. However, the state’s reliance on sales and property taxes has often led to discussions about alternative revenue streams, particularly for funding public services. The current proposal, dubbed the "millionaires tax" by its supporters, aims to create a new, progressive tax bracket specifically for the state’s wealthiest residents.
The legislative journey of this proposed income tax has been marked by fervent debate. Proponents, including leading state lawmakers, argue that the tax is a fair and necessary measure to ensure that those with the greatest capacity to contribute do so, thereby funding essential public services and reducing the tax burden on middle and lower-income families. They point to the fact that 41 other states have some form of income tax, suggesting that Washington would not be stepping into uncharted territory.
Conversely, opponents express deep concern about the potential economic repercussions. Their primary argument centers on the principle of capital flight, suggesting that imposing a significant income tax on high earners will incentivize them to relocate their primary residence and their investments to states with more favorable tax policies. This, they contend, would not only diminish the state’s tax base but also lead to a loss of philanthropic contributions and job creation.
The "Millionaires Tax" Explained
The proposed legislation, officially known as the income tax on high earners, would levy a 9.9% tax on annual household income exceeding $1 million. This threshold was carefully chosen to target a specific segment of the population, with lawmakers emphasizing that the vast majority of Washington residents would not be affected by this measure. Supporters argue that this is a modest contribution from those who have benefited the most from the state’s economic prosperity.
The bill’s proponents also highlight provisions designed to support small businesses. For instance, an amendment introduced by Rep. April Berg aims to increase the business and occupation (B&O) tax return filing threshold to $250,000. This change, Berg stated, would exempt an estimated 49% of businesses from paying B&O taxes altogether, providing much-needed relief to small enterprises.
Arguments for and Against Capital Flight
The debate over capital flight is not merely theoretical; it is informed by past events and expert analyses, though experts themselves are divided on the extent of its impact.
Critics frequently cite the high-profile move of Amazon founder Jeff Bezos from Washington to Florida in 2023. This relocation occurred shortly after the implementation of Washington’s capital gains tax, leading critics to argue that tax policies were a significant motivating factor. Forbes estimated that Washington lost approximately $954 million in potential tax revenue in 2024 due to Bezos’s departure, a stark figure that underscores the concerns of those wary of further tax increases.
However, Governor Bob Ferguson, a strong proponent of the "millionaires tax," has countered that personal reasons, such as proximity to family, may have been the primary drivers for Bezos’s move. He has also expressed skepticism about the broader capital flight predictions, stating during a legislative preview, "Considering the fact that I think 41 states have an income tax, I don’t think that’s going to happen."
Further complicating the issue, PJ Tabit, principal economic policy analyst at The Conference Board, a nonpartisan, nonprofit business-led public policy center, noted that research on capital flight is "mixed overall." He emphasized the difficulty in making broad generalizations due to the diverse tax structures and economic dynamics across different states and countries. "People have varying reasons for choosing where to live, be it job opportunities, quality of life or family commitments," Tabit explained. "From a research perspective, it’s actually quite difficult to suss out the role of tax policy in those decisions."
Expert Opinions and Supporting Data
In contrast to Tabit’s more cautious assessment, Jared Walczak, a senior fellow at the Tax Foundation, a nonpartisan tax-policy nonprofit, believes the link between taxation and relocation is more direct and widely accepted. "At some level, this is just intuitive and not really debated," Walczak stated. He pointed to a growing body of economic research over the past decade that increasingly supports the notion of "meaningful capital flight."
Walczak provided examples of states that have reportedly experienced such phenomena. He noted that California has seen some billionaires depart in anticipation of or following previous tax increases, and companies like Hewlett-Packard (HP) and Tesla have relocated from California to Texas. He also highlighted that as taxes have risen in Seattle, jobs have begun to shift to neighboring jurisdictions. Walczak warned that if Washington’s income tax passes, high earners in Seattle could face the highest combined local and state top tax rate in the nation, creating a "very strong incentive to locate elsewhere" and encouraging businesses to "hire elsewhere."
Joe Wallin, a Seattle-based startup attorney, echoed these concerns in a recent GeekWire opinion piece, arguing that the income tax would be detrimental to the state’s burgeoning startup economy. He also cited IRS data suggesting that in the first year after Washington’s capital gains tax was enacted, the state experienced a net loss of $1.66 billion in adjusted gross income.
However, the narrative is not entirely one-sided. Danny Westneat, a columnist for The Seattle Times, has presented counterarguments. He pointed to Massachusetts, where voters passed a millionaire’s tax in 2022. Despite predictions of a wealth exodus, the measure reportedly generated more than double the projected revenue in its first two years, bringing in $5.7 billion instead of the anticipated $2.3 billion.
Broader Economic and Social Implications
The potential for capital flight extends beyond mere revenue loss; it touches upon the broader economic and social fabric of the state.
Philanthropy and Community Investment: Critics of the proposed tax express concern about the loss of philanthropic contributions. State Representative April Connors, House Republican floor leader, shared an anecdote about a constituent who relocated their primary residence to Montana. The year prior, this individual had donated $100,000 to their local community in the Tri-Cities area. Connors lamented, "We’re not only losing people that are paying into our tax base, but we’re losing people who are paying with their philanthropy dollars into the Tri-Cities." This highlights the dual impact of losing both tax revenue and community support from wealthy individuals.
Impact on Business and Job Creation: The argument that higher taxes can deter businesses and job creation is a recurring theme among opponents. The Association of Washington Business released a survey indicating that 44% of the state’s business leaders are considering moving their personal domicile outside of Washington. This sentiment suggests a potential for a significant brain drain and loss of entrepreneurial spirit if tax policies become perceived as overly burdensome.
Estate Tax Precedent: The current debate over the income tax on millionaires also draws parallels to recent changes in Washington’s estate tax. Last session, Democrats increased the estate tax, raising the top rate from 20% to 35%, making it the highest in the nation. Senate Majority Leader Jamie Pedersen acknowledged that legislators have heard anecdotal reports of residents looking to switch their legal residence to other states to avoid this estate tax. However, Pedersen maintained that the income tax, with its top marginal rate of 9.9%, would not be as extreme an outlier as the estate tax, suggesting it is "not out of line with a large number of the 41 other states that have some form of a personal income tax."

Official Responses and Future Outlook
The differing perspectives from key political figures highlight the divide in how the proposed tax is viewed. Governor Ferguson remains optimistic that the tax will not lead to significant capital flight, citing the prevalence of income taxes in other states. Similarly, Senate Majority Leader Jamie Pedersen believes the 9.9% rate is not an outlier compared to other states with income taxes.
On the other side, Republican leaders and business groups express strong reservations. Senate Minority Leader John Braun and Representative April Connors have highlighted anecdotal evidence and survey data suggesting a growing inclination among business leaders and high-net-worth individuals to consider relocating. The Association of Washington Business survey, indicating that nearly half of state business leaders are contemplating moving their domicile, serves as a significant indicator of this sentiment.
The ultimate impact of Washington’s proposed "millionaires tax" on capital flight remains to be seen. Economic analyses are varied, and real-world outcomes can be influenced by a multitude of factors beyond tax policy, including quality of life, job opportunities, and personal circumstances. However, the intensity of the debate underscores the delicate balance states must strike between generating necessary revenue and fostering an environment conducive to economic growth and prosperity. As the legislation moves forward, stakeholders will be closely watching to see if Washington State becomes a case study in the complex interplay between taxation, wealth, and mobility.
