Navigating the Surge in Millionaire and Wealth Taxes: A 2026 National Update
At Blumark Tax Advisors, we consistently monitor the shifting legislative landscape to ensure our clients in Auburn Hills and across the country are prepared for changes that impact their wealth. Currently, the movement toward 'millionaire taxes' is gaining significant momentum. From coast to coast, state legislatures are debating how to leverage high earners, luxury property owners, and billionaires to address budget shortfalls and fund public initiatives like education and infrastructure. For the high-income professionals and business owners we serve, staying informed on these developments is the first step in proactive tax strategy.
California: A High-Stakes Vote on the Billionaire Tax Act
California continues to lead the nation in aggressive tax proposals. Supporters of the 2026 Billionaire Tax Act have successfully gathered the signatures required to place a significant one-time 5% wealth tax on the November 2026 ballot. This measure specifically targets individuals with a net worth exceeding $1 billion. While proponents argue it will generate billions for healthcare and social programs, critics—including Governor Gavin Newsom—express concern that such a tax could accelerate the migration of high-net-worth individuals to more tax-friendly jurisdictions.
Maine: New Surcharges Now in Effect
While some states are still debating, Maine has officially transitioned into law. Earlier this year, Governor Janet Mills signed a budget that introduces a 2% surcharge on individual income exceeding $1 million. For those filing jointly or as heads of household, the threshold is set at $1.5 million. Retroactive to January 1, 2026, this tax is expected to contribute nearly $100 million annually toward public funding, a move that requires immediate attention for our clients with interests in the Pine Tree State.
Illinois: A Temporary Reprieve for Millionaires
In Illinois, the push for a targeted tax on high earners has stalled. A proposed constitutional amendment that would have allowed for an additional 3% tax on income over $1 million failed to secure the necessary legislative support. Consequently, Illinois voters will not see this measure on the November 2026 ballot, though we anticipate this conversation will resurface in future sessions as budget pressures continue.
New York: Targeting Luxury Real Estate with a Pied-à-Terre Tax
New York is shifting its focus toward real estate assets rather than just traditional income. Governor Kathy Hochul has introduced a pied-à-terre tax specifically aimed at second homes in New York City with valuations of $5 million or more. This annual surcharge targets ultra-wealthy non-residents who use luxury properties as investment vehicles. While it promises a new revenue stream for the city, it also presents complex valuation challenges and potential legal hurdles for property owners.
Washington State: A Legal Battle Over the 9.9% Tax
Historically a state without a traditional income tax, Washington has taken a bold step by enacting a 9.9% tax on income above $1 million. Governor Bob Ferguson signed this into law in March 2026, with implementation set for 2028. However, the legal community is already engaged, as opponents argue the tax violates the state’s constitution, which historically treats income as property and limits such levies. This is a critical development for business owners with West Coast operations.
Massachusetts and Oregon: Testing the Wealth Tax Waters
Massachusetts remains a vital case study for the rest of the country. Since 2023, the state has applied an additional 4% surtax on income above its annual threshold. Meanwhile, Oregon may soon follow suit with The Very Rich Pay Their Fair Share Act. This proposed initiative seeks to tax a broad range of assets, including stock options, business interests, and bonds, for the state’s wealthiest residents, potentially appearing on the 2026 ballot.
Northeast Updates: Vermont, Connecticut, and Maryland
In Vermont, lawmakers are considering a top income tax bracket of 13.3% for the top 1% of earners, specifically joint filers with income over $586,000. In Connecticut, while no new law has passed, advocates are gaining ground with high-profile protests and petitions for billionaire-specific reforms. Maryland is also exploring House Bill 1238, which would introduce a tax on net worth exceeding $1 billion to fund a state stabilization account.
Rhode Island and New Jersey: Surcharges and Mansion Taxes
Rhode Island has introduced a unique 0.5% annual surcharge on non-owner-occupied properties valued above $1 million, often referred to as the 'Taylor Swift Tax.' This affects luxury second homes used for fewer than 183 days a year. Similarly, New Jersey has expanded its 'mansion tax' into a tiered system, where real estate sales over $3.5 million are taxed at 3.5%. For our clients involved in high-end real estate transactions, these structural changes significantly impact the bottom line.
Hawaii and the Federal Landscape
Hawaii's legislative session saw several high-end property tax hikes stall in the Senate, though local efforts in Hawaiʻi County continue to target homes over $4 million. On the federal level, Senator Elizabeth Warren has reintroduced the Ultra-Millionaire Tax Act, proposing a 2% annual tax on net worth over $50 million. While federal wealth taxes face significant political opposition, their presence in the national discourse signals a long-term shift in tax policy priorities.
Strategies for a Changing Environment
The term 'millionaire tax' now encompasses a diverse array of policies, including income surtaxes, wealth taxes, mansion taxes, and luxury property surcharges. Whether it is Maine's new income surcharge or New Jersey's tiered mansion tax, the common thread is clear: high-income and high-asset individuals are facing a more complex compliance environment. For Michigan-based professionals and those with multi-state footprints, these changes necessitate a proactive, advisory-first approach to financial planning. If you are concerned about how these evolving state and federal policies might impact your wealth, the team at Blumark Tax Advisors is here to provide the clarity and strategy you need.

State tax policy can change quickly. This article is current on the date of publication, April 29, 2026.
The legal challenges unfolding in Washington provide a critical look at the constitutional boundaries of state taxation. For our clients with business entities or significant investments in the Pacific Northwest, the 9.9 percent tax represents more than just a financial hit; it represents a fundamental shift in how the state defines property. For nearly a century, Washington’s courts have held that income is a form of property, which by law must be taxed at a uniform rate. By classifying this new surcharge as an excise tax rather than a traditional income tax, the legislature is testing a legal theory that could have ripple effects across other states with similar constitutional restrictions. If this tax survives judicial scrutiny, it may provide a roadmap for other jurisdictions to bypass voter-mandated tax limits, making proactive entity structuring even more essential for high-net-worth families who operate across state lines.
In the Northeast, the Massachusetts 'Fair Share' surtax is entering its fourth year of implementation, offering a wealth of data on taxpayer behavior. One of the most common questions we receive in our Auburn Hills office is whether these taxes truly trigger a 'wealth flight' to lower-tax regions. While early reports indicate that some ultra-high-earners have indeed relocated to zero-income-tax states like Florida or Tennessee, many others remain due to deep business ties or family roots. However, the surtax has forced a change in how these individuals realize income. We are seeing an increase in the use of specialized trusts and the strategic timing of capital gains to stay below the million-dollar threshold where possible. This type of strategic timing is a hallmark of the advisory services we provide at Blumark Tax Advisors, as it allows clients to maintain their lifestyle while minimizing unnecessary tax exposure through meticulous planning.
The valuation disputes inherent in New York’s proposed pied-à-terre tax also serve as a warning for luxury property owners. When a tax is based on the appraised value of a second home rather than a simple transaction price, it introduces a layer of subjectivity that can lead to years of administrative litigation. Property owners may find themselves in a position where the city’s assessment of their penthouse or vacation home far exceeds the current market reality, particularly in a fluctuating real estate market. This underscores the importance of maintaining rigorous records and potentially engaging independent appraisers as part of a broader wealth preservation strategy. For our clients who view real estate as a key component of their portfolio, these developments necessitate a more defensive posture regarding property holding structures, such as using limited liability companies to manage the potential tax burden.
Furthermore, the ripple effects of these state-level movements are felt even here in Michigan. While the Wolverine State maintains a relatively straightforward flat tax system, the 'millionaire tax' trend influences the broader economic climate and federal policy discussions. When high-tax states successfully implement wealth surcharges, it emboldens federal lawmakers to pursue similar initiatives, like the Ultra-Millionaire Tax Act. At Blumark, we emphasize to our growth-focused entrepreneurs that their tax strategy must be national in scope. Whether you are expanding your business into a state like Maine or purchasing a retirement home in Rhode Island, the tax implications are no longer confined to your primary residence. Navigating this web of surcharges, mansion taxes, and wealth levies requires a partner who understands the nuances of multi-state compliance and can help you maintain financial control across all your holdings. By staying ahead of these trends, we help you grow with less stress and more precision.
