The Global Shift Toward Wealth Taxes: A 2026 National Update for High-Net-Worth Individuals
At MJ Ahmed CPA PLLC, we have spent over 25 years helping high-net-worth clients navigate the shifting sands of the American tax code. Whether you are managing assets in the Dallas-Fort Worth area or overseas, the current trend toward 'millionaire taxes' is impossible to ignore. Across the nation, a wave of legislative proposals is targeting high earners, luxury property owners, and billionaires to address budget shortfalls and fund public initiatives.
We are seeing a diverse range of strategies, from traditional income surtaxes to innovative wealth levies. For our clients with multi-state footprints, understanding these developments is no longer optional—it is a critical component of proactive tax planning and wealth preservation. Here is a comprehensive look at the current state of the millionaire tax movement as of April 2026.
California: The 2026 Billionaire Tax Act
California continues to lead the nation in aggressive tax experimentation. Proposers 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. If passed, this measure would target individuals with a net worth exceeding $1 billion.
The revenue, estimated in the tens of billions, is earmarked for healthcare programs to offset potential federal funding reductions. While supporters view this as a necessary step for equity, critics—including Governor Gavin Newsom—express concerns regarding 'wealth flight,' where the state's most significant taxpayers may relocate to lower-tax jurisdictions like Texas or Florida to avoid such heavy levies.
Maine: A New Surcharge for High Earners
Maine has officially moved from debate to implementation. Governor Janet Mills recently signed a budget package featuring a new 2% surcharge on individual income over $1 million. For those filing jointly or as heads of household, the threshold moves to $1.5 million.
Crucially, this tax is retroactive to January 1, 2026. For those with business interests or residency in the Northeast, this adds a layer of complexity to current-year estimated tax payments. The state expects to generate nearly $100 million annually to bolster public programming.
Illinois: Proposals Hit a Roadblock
In contrast to the momentum in other states, the millionaire tax push in Illinois 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 likely not see this measure on the November 2026 ballot, providing a temporary reprieve for high earners in the Prairie State.
New York: Targeting the 'Pied-à-Terre' Market
New York’s strategy focuses heavily on the real estate sector. Governor Kathy Hochul is advocating for a pied-à-terre tax specifically targeting luxury second homes in New York City. The proposal suggests an annual surcharge on non-resident-owned properties valued at $5 million or more.
While supporters argue this taxes investment vehicles rather than residents, critics warn of prolonged legal battles regarding property valuations. For our clients holding significant New York real estate portfolios, this represents a potential recurring annual cost that must be factored into the total return on investment.
Washington: A Constitutional Battle Over Income
Washington state has traditionally avoided a state income tax, but that landscape is shifting. Governor Bob Ferguson has signed a new 9.9% tax on income above $1 million. Set to take effect in 2028, the law is already facing significant legal scrutiny. Opponents argue that the state constitution treats income as property, which would strictly limit the government's ability to tax it in this manner. The outcome of this legal challenge will be a landmark moment for Western tax policy.
Massachusetts: The Fair Share Surtax Test Case
Massachusetts remains a primary case study for the movement. Since 2023, the state has utilized an additional 4% surtax on taxable income above the inflation-adjusted threshold. While the revenue has successfully funded education and infrastructure, the long-term impact on high-earner out-migration is still being debated by economists and tax professionals alike.
Oregon and Vermont: Pushing the Upper Limits
Oregon is currently weighing The Very Rich Pay Their Fair Share Act, a proposed initiative that would tax broad asset classes, including stocks, bonds, and business interests. Meanwhile, Vermont lawmakers are debating a top income tax rate of 13.3% on income above $586,000. If enacted, this would give Vermont one of the highest top marginal rates in the entire country.
The Rising Tide in Maryland, Connecticut, and Rhode Island
- Maryland: House Bill 1238 proposes a one-time tax on net worth exceeding $1 billion, though it currently remains in the legislative phase.
- Connecticut: While no new law has been passed, public pressure and legislative proposals continue to target high-value property and wealth.
- Rhode Island: Effective July 1, 2026, the state will implement a 0.5% annual surcharge on the value of non-owner-occupied residential properties assessed at $1 million or more. This 'Taylor Swift Tax' exempts primary residences and long-term rentals.
New Jersey: Mansion Tax Evolution
New Jersey has already moved forward by expanding its tiered mansion tax. Sales over $3.5 million are now taxed at 3.5%, departing from the previous flat 1% rate. This tiered system significantly increases the closing costs for luxury real estate transactions in the state.
The Federal Outlook: The Ultra-Millionaire Tax Act
On Capitol Hill, the Ultra-Millionaire Tax Act has been reintroduced. This federal proposal seeks a 2% annual tax on household net worth over $50 million, with an additional 1% surtax for billionaires. While it faces steep political resistance, its continued presence in the national discourse signals a shifting appetite for wealth-based taxation at the highest levels of government.

State tax policy can change quickly. This article is current on the date of publication, April 29, 2026.
The complexity of these new regulations extends far beyond the simple calculation of a tax bill. For high-net-worth individuals, the primary concern is the potential for aggressive residency audits. When a taxpayer attempts to transition from a high-tax jurisdiction like California or New York to a more favorable environment like the Dallas-Fort Worth area, the departing state often initiates a meticulous review of the individual’s lifestyle and connections. These audits go deeper than the traditional 183-day rule, examining everything from where your primary voting registration is held to the location of your most significant personal items. At MJ Ahmed CPA PLLC, we have seen that establishing a new domicile requires a comprehensive strategy and clear documentation to withstand the scrutiny of revenue officers seeking to maintain their tax base.
Furthermore, the administrative burden of wealth taxes, such as those proposed in Oregon, creates a unique set of challenges for business owners and investors. Valuing illiquid assets—including private equity interests, closely held business shares, and specialized real estate holdings—is a complex and often subjective process. Unlike publicly traded securities, these assets require formal appraisals that can lead to valuation disputes with state authorities. This creates a recurring cycle of compliance costs and potential legal hurdles that can significantly impact a family's long-term wealth preservation strategy. We are actively working with our clients to evaluate their current holdings and implement structures that provide both transparency and protection in the face of these evolving mandates.
Ultimately, the surge in millionaire and billionaire tax proposals highlights the need for a more dynamic and multi-state tax planning approach. As these laws become more common, the traditional boundaries of state taxation are blurring. Whether it is a luxury property surcharge or a tiered mansion tax, every high-value transaction now requires a careful analysis of the local tax landscape. For over 25 years, we have guided our clients through these types of fiscal transitions, providing the insight and technical expertise needed to manage cross-border and multi-state tax obligations efficiently. By anticipating these shifts before they become law, we help ensure that your financial future remains secure and that your tax strategy remains as resilient as the businesses and legacies you have built.
