The Growing Millionaire Tax Movement: A 2026 Status Report for High Earners
Millionaire taxes are experiencing a significant resurgence in 2026. Across the United States, state legislatures and advocacy groups are aggressively debating whether high-income earners, luxury property owners, and billionaires should shoulder a larger portion of the fiscal burden. These proposals are often framed as necessary solutions for funding public infrastructure, education, and healthcare, or simply to close persistent budget gaps.
For the high-impact professionals and business owners we serve at Golden State Tax & Business Services, these aren't just headlines—they are critical variables in a multi-year tax strategy. While some of these measures have already been codified into law, others are facing legal hurdles or awaiting a final decision from voters. Here is an updated national roundup of the current state of millionaire and wealth tax legislation.
California: The 2026 Billionaire Tax Act and the Ballot Box
Closer to home for our Rocklin-based firm, California continues to lead with some of the most aggressive tax proposals in the nation. Proponents of the 2026 Billionaire Tax Act have successfully gathered the signatures required to place a one-time 5% wealth tax on the November 2026 ballot. This measure specifically targets individuals with a net worth exceeding $1 billion.
While the revenue is earmarked for healthcare initiatives, the proposal remains highly controversial. Critics, including Governor Gavin Newsom and prominent Silicon Valley figures, argue that such a levy could accelerate the migration of high-net-worth residents to tax-friendlier jurisdictions. For our clients in California, this reinforces the importance of proactive residency and asset protection planning.
Maine: A New Surcharge for Seven-Figure Earners
Maine has officially transitioned from debate to implementation. In April 2026, Governor Janet Mills approved a budget package that introduces a 2% surcharge on individual income exceeding $1 million. For those filing as head of household or jointly, the threshold sits at $1.5 million. Notably, the surcharge is retroactive to January 1, 2026, creating an immediate need for estimated tax adjustments for affected taxpayers.
Illinois: Legislative Momentum Stalls
In contrast to the movement in the Northeast, the latest push for a millionaire tax in Illinois has lost its footing. A proposed constitutional amendment aimed to introduce a 3% tax on income over $1 million, but it failed to garner the necessary support in the Illinois House. This effectively removes the measure from the November 2026 ballot, providing high earners in the Prairie State a temporary reprieve from new state-level income surcharges.
New York: Targeting Luxury "Pied-à-Terre" Residences
New York is shifting its focus toward real estate assets rather than pure income. Governor Kathy Hochul has championed a pied-à-terre tax specifically targeting second homes in New York City valued at $5 million or more. The annual surcharge is designed to capture revenue from nonresident owners who utilize high-value properties as investment vehicles. However, the proposal faces potential litigation over property valuation methods and constitutional challenges.
Washington: High-Earner Tax Enacted Amidst Legal Challenges
Washington state has historically avoided traditional income taxes, but that paradigm is shifting. Governor Bob Ferguson signed a law in March 2026 establishing a 9.9% tax on income above $1 million, set to take effect in 2028. Opponents have already mobilized, filing legal challenges that argue the tax violates the state’s constitution, which treats income as property and limits the rates at which it can be taxed.
Massachusetts: The Fair Share Surtax Test Case
Massachusetts remains the primary case study for these policies. Since 2023, the state has enforced a 4% surtax on taxable income above its annual threshold. While the revenue has significantly bolstered education and transportation budgets, economists and tax professionals continue to monitor whether the surtax is driving high-earning residents to move to neighboring states like New Hampshire.
Oregon and Vermont: Pushing the Ceiling on Top Rates
In Oregon, advocates are working to qualify The Very Rich Pay Their Fair Share Act for the 2026 ballot, which would tax assets like stock options and business interests. Meanwhile, Vermont lawmakers are debating a new top income tax bracket that could reach 13.3% for income above $586,000 for joint filers, potentially giving Vermont one of the highest top rates in the country.
Regional Shifts: Connecticut, Maryland, and Rhode Island
While Connecticut has not yet passed a new bill, activists are putting significant pressure on the legislature for a billionaire tax. In Maryland, House Bill 1238 proposes a net worth tax on billionaires to fund state investments. Rhode Island has taken a different route with its “Taylor Swift Tax,” a 0.5% annual surcharge on the value of non-owner-occupied homes worth over $1 million, effective July 2026.
New Jersey and Hawaii: Refined Mansion Taxes
New Jersey expanded its tiered mansion tax in 2025, with sales over $3.5 million now taxed at 3.5%. Hawaii remains a battleground for similar proposals; while several state-level hikes stalled recently, local counties continue to explore higher property taxes on luxury homes valued over $4 million.
The Federal Landscape: The Ultra-Millionaire Tax Act
At the federal level, the Ultra-Millionaire Tax Act has been reintroduced, proposing a 2% annual tax on household net worth over $50 million. While federal gridlock makes immediate passage unlikely, the persistent reintroduction of this bill signals that wealth taxation remains a cornerstone of the national political dialogue.
The “millionaire tax” label has evolved into a broad umbrella covering income surtaxes, wealth levies, and luxury real estate surcharges. For the modern taxpayer, the lesson is clear: high-income policy is fluid. At Golden State Tax & Business Services, we believe that accuracy and compliance are only the beginning. True financial confidence comes from forward-looking planning that anticipates these legislative shifts.

State tax policy can change quickly. This article is current on the date of publication, April 29, 2026.
Beyond the primary legislative updates mentioned, it is crucial to understand the broader implications of trailing nexus and exit taxes that are frequently discussed alongside these wealth-based proposals. In the California context, proponents have often debated a provision that would allow the state to continue taxing a portion of an individual's wealth for several years even after they have officially changed their domicile to another state. This represents a revolutionary shift in state tax law, which has historically relied on a simple snapshot of residency on a specific date. For the high-earning W-2 professionals and business owners we work with, this means that moving out of state is no longer an immediate, one-size-fits-all solution for tax minimization. Instead, it requires a multi-year strategic plan to mitigate the impact of these trailing tax obligations. When the state begins to evaluate your global asset base over a five- or ten-year horizon, the complexity of maintaining compliance increases exponentially.
Another layer of complexity involves the valuation of illiquid assets, such as private equity holdings, closely held S-corporations, and specialized real estate. Unlike a standard income tax that focuses on annual cash flow, a wealth tax requires a precise annual determination of fair market value for everything you own. This can be a significant administrative hurdle for the small business owners and high-impact professionals we serve in Rocklin and across the country. Determining the value of a private company every year is not just a matter of checking a stock ticker; it often requires formal appraisals, forensic accounting, and a robust defense of the valuation methodology used. From our perspective, this underscores the importance of a modern, tech-forward approach to documentation. In an environment where state tax authorities are incentivized to scrutinize asset values, having a clear, data-backed record of how your business was valued is essential for avoiding the stress of an audit—which we often compare to a financial dental cleaning.
We must also address the interaction between these new millionaire surcharges and the existing Pass-Through Entity Tax (PTET) structures that have become common in recent years. Many LLC and S-corporation owners utilize the PTET to circumvent the federal SALT cap, but new state-level surtaxes can complicate this strategy. In states like Maine or Washington, the introduction of a new surcharge on high earners may not align perfectly with existing PTET credits. This can lead to a scenario where a taxpayer is effectively taxed twice at the state level on the same dollar of income—once through the business entity and again through a personal income surcharge that does not fully recognize the entity-level payment. Proactive tax planning is the only way to navigate these overlapping rules. We work closely with our clients to adjust estimated tax strategies and compensation planning in real-time as these state laws evolve, ensuring that their cash flow remains stable despite a shifting tax landscape.
Generational wealth transfer and the use of trusts also face new challenges under these proposals. While many of the millionaire and billionaire tax bills are still being refined, several include provisions aimed at assets held in irrevocable trusts. The location of the trustee, the residency of the beneficiaries, and the specific distribution powers within the trust document can all trigger different tax outcomes under these new laws. For families with complex wealth structures, it is no longer enough to set up a trust and forget about it. These vehicles must be regularly reviewed to ensure they remain tax-efficient in light of new state-level surcharges. Our role as a trusted advisor is to help you stay ahead of these trends, guiding you through the technical nuances of trust taxation and ensuring your financial legacy is protected from unnecessary tax friction.
The mansion tax and second-home surcharges also create a cumulative effect for taxpayers with multi-state footprints. If you own a primary residence in California and a vacation home in Rhode Island, you could find yourself subject to high-end property surcharges in both jurisdictions, each with its own set of exemptions and thresholds. For instance, the Rhode Island surcharge specifically targets non-owner-occupied properties used fewer than 183 days a year, while other states may use different metrics for luxury status. This patchwork of state laws makes it vital to have a comprehensive view of your entire portfolio. At Golden State Tax & Business Services, we focus on this type of multi-state accuracy and compliance, helping you understand how a change in one state's law can ripple through your entire financial picture. By integrating AI and automation into our workflows, we can quickly model these different scenarios and help you make confident decisions about your property and business holdings.
In addition to these structural changes, the political climate suggests that the contagion effect of these taxes is real. When a state like Massachusetts reports significant revenue gains from its millionaire surtax, other states facing budget deficits are likely to follow suit. This makes tax planning a continuous process rather than a once-a-year event. For the busy professionals and closely held business owners we serve, staying informed about these trends is a matter of long-term financial health. We view our proactive planning services as a way to give you greater control over your financial future, providing clear and practical guidance that avoids jargon and focuses on results. Whether you are navigating a new S-corporation structure or planning for a significant capital gain, understanding the evolving millionaire tax movement is a crucial part of your overall financial strategy.
