The Rising Tide of Millionaire Taxes: A 2026 Status Report for High Earners
Wealth-based taxation is entering a new era of legislative scrutiny. Across the United States, state capitals are currently weighing whether high-income earners, luxury real estate investors, and billionaires should carry a larger share of the fiscal burden to address infrastructure, education, and looming budget deficits. While some of these initiatives have successfully transitioned into law, others are facing fierce legal opposition or stalling in legislative committees.
For our clients at Haley Claypool & Associates, particularly those with multi-state footprints, understanding these shifts is essential for long-term tax planning. Here is the current state of play for the most significant millionaire and wealth tax movements across the country.
California: The Billionaire Tax Act Eyes the 2026 Ballot
Being based in Newport Beach, we are watching the California landscape with particular interest. Proponents of the 2026 Billionaire Tax Act have confirmed they secured the necessary signatures to put a landmark 5% one-time wealth tax before voters this November. Targeted at residents with a net worth exceeding $1 billion, the measure is intended to shore up healthcare funding. While supporters view it as a necessary revenue stream, high-profile critics—including Governor Gavin Newsom—caution that such aggressive measures could accelerate the migration of top-tier taxpayers out of the state.
Maine: A New Millionaire Surcharge Becomes Reality
Maine has officially joined the ranks of states with targeted high-earner surcharges. Governor Janet Mills recently signed a budget package introducing a 2% surcharge on individual income exceeding $1 million. For those filing jointly, the threshold sits at $1.5 million. This tax is retroactive to January 1, 2026, and is projected to generate nearly $100 million annually for public services.
Illinois: Momentum for High-Earner Tax Stalls
The push for a graduated-style millionaire tax in Illinois has hit a significant roadblock. A proposed constitutional amendment that would have enabled a 3% tax on income over $1 million failed to clear the Illinois House. This effectively prevents the measure from appearing on the 2026 ballot, providing a temporary reprieve for high-income residents in the state.
New York: Targeting Luxury Real Estate with a Pied-à-Terre Tax
New York is shifting its focus from traditional income toward high-value secondary residences. Governor Kathy Hochul has introduced a pied-à-terre tax proposal aimed at New York City second homes valued at $5 million or more. Designed to treat luxury real estate as an investment vehicle rather than just a residence, the annual surcharge would target ultra-wealthy non-residents, though critics anticipate complex valuation disputes and legal challenges.
Washington: New High-Earner Tax Faces Immediate Legal Hurdles
Washington state has long been a haven for those avoiding state income tax, but that dynamic is changing. Governor Bob Ferguson has signed a 9.9% tax on income above $1 million, slated for implementation in 2028. The move has already triggered lawsuits, as opponents argue the tax violates Washington’s constitutional treatment of income as property, which limits such levies.
Massachusetts: The "Fair Share" Surtax as a National Blueprint
Now in its third year, the Massachusetts 4% surtax on taxable income above the annual threshold remains a critical test case. Revenue from the tax is strictly earmarked for education and transportation. While the state has seen robust collections, economists and tax professionals continue to monitor whether the tax is influencing the relocation decisions of the state's most affluent residents.
Oregon and Vermont: Pushing the Upper Limits of Tax Brackets
In the Pacific Northwest, Oregon activists are working to qualify The Very Rich Pay Their Fair Share Act for the ballot. This initiative would tax broad asset classes, including stocks and business interests. Meanwhile, Vermont is considering a new top bracket of 13.3% on income above $586,000 for joint filers, which would give the state one of the highest top rates in the country.
Connecticut, Maryland, and Rhode Island: Creative Luxury Levies
Connecticut advocates recently marked Tax Day with high-profile calls for a billionaire tax, though it remains in the advocacy stage. In Maryland, net worth above $1 billion could soon be subject to a one-time stabilization tax under House Bill 1238. Rhode Island has taken a different route with the “Taylor Swift Tax,” a 0.5% annual surcharge on non-owner-occupied properties valued over $1 million used primarily for vacations.
New Jersey and Hawaii: Real Estate and Stalled Proposals
New Jersey has already moved forward by expanding its mansion tax. Sales over $3.5 million are now taxed at 3.5%, reflecting a tiered approach to high-end real estate transfers. In Hawaii, while several state-level hikes on homes valued above $4 million stalled in the Senate, the debate over using luxury property taxes to fund housing remains active.
Federal Landscape: The Ultra-Millionaire Tax Returns
On the national stage, the Ultra-Millionaire Tax Act has been reintroduced, proposing a 2% annual tax on net worth exceeding $50 million. While political gridlock makes federal passage difficult, the proposal keeps the concept of a national wealth tax central to the political discourse.
The definition of a "millionaire tax" has expanded to include income surcharges, wealth taxes, mansion taxes, and second-home levies.

The administrative complexities of wealth taxation represent a paradigm shift in tax compliance. For decades, the American tax system has primarily relied on realized income—money that has actually changed hands through sales, wages, or dividends. Transitioning to a model that taxes unrealized gains or total net worth requires a level of transparency and record-keeping that few individuals are currently prepared for. This includes maintaining detailed basis records for every asset owned, from primary residences in Newport Beach to minority stakes in tech startups or private equity funds. For our clients at Haley Claypool & Associates, this means that tax season is no longer a once-a-year event but a year-round process of asset monitoring and valuation adjustments to ensure compliance with these emerging state mandates.
Beyond the administrative burden, there is the ongoing psychological and economic impact of tax competition between states. High-net-worth individuals are increasingly mobile, and current data suggests that while some residents are willing to pay a premium for the lifestyle and infrastructure offered by states like California, New York, or Massachusetts, there is a definitive breaking point. When the combined state and federal marginal tax rate approaches or exceeds 50%, the incentive to relocate to tax-favorable jurisdictions becomes a primary financial driver. This movement does not just take tax dollars away; it often removes the capital that fuels local venture investment, community philanthropy, and local job creation.
In the context of the Taylor Swift Tax in Rhode Island and other luxury property surcharges, we are seeing a strategic shift toward taxing wealth in place. Even if a resident is not earning a high income in a specific year, the sheer value of their real estate holdings can now trigger a substantial tax bill. This is particularly relevant for individuals who may be asset-rich but cash-poor, such as retirees living in homes they purchased decades ago that have since skyrocketed in value. While most current legislation targets non-owner-occupied properties or sets extremely high valuation thresholds, the legal precedent for using real estate as a primary vehicle for wealth redistribution is clearly being established at the state level.
The role of the 'exit tax' is perhaps the most controversial element of these new proposals. Some California lawmakers have debated whether the state can continue to tax individuals on their wealth for several years after they have established residency elsewhere. These 'tail provisions' are designed to prevent taxpayers from moving just months before a liquidity event or the effective date of a new tax law. However, these measures face significant constitutional hurdles regarding the right to travel and the federal government's authority over interstate commerce. For high-net-worth families in our Newport Beach community, these provisions make the timing of a relocation a critical part of their five-year tax plan.
Strategic planning remains the most effective defense against this rising tide of varied tax policies. This often includes the use of irrevocable trusts, sophisticated gifting strategies, and the careful selection of state tax residency before a major financial event occurs. For business owners, this might involve restructuring their entities to take advantage of specific state-level exemptions or credits that mitigate the impact of income surcharges. The key takeaway for high-earning individuals is that the millionaire tax is no longer a single, isolated policy; it is a multifaceted legislative movement that requires a proactive, multi-state approach to financial management. We are committed to helping our clients navigate these complexities, ensuring their assets are protected and their long-term financial goals remain achievable regardless of shifting political winds.
