Maine has enacted a new millionaire tax, joining other high-tax blue states, after Democratic Governor Janet Mills signed the measure into law. The legislation, known as LD 2212, introduces a 2% income tax surcharge on individual incomes exceeding $1 million and $1.5 million for joint filers, effective January 1, 2026. This change raises Maine’s top marginal income tax rate from 7.15% to 9.15% and is projected to affect approximately 2,600 filers, generating an estimated $160 million in revenue over the next two years [1].
Governor Mills and progressive lawmakers defend the tax as a necessary response to federal policies and a means to fund initiatives such as permanent Free Community College, increased property tax relief, expanded childcare funding, and sustained support for schools and healthcare. Mills stated, “This budget will deliver significant relief to Maine people facing rising prices because of the shortsighted actions of the Trump Administration,” emphasizing the direct benefits to Maine residents and investments in critical services [1]. State Rep. Cheryl Golek described the surcharge as a reasonable and widely supported step toward a fairer tax system [1].
However, the law has sparked immediate criticism from business groups and conservative organizations. The Maine State Chamber of Commerce warned that the surcharge could negatively impact local entrepreneurship and retirement, particularly for small and family-owned businesses. Former Maine senator and business owner Brian Langley argued that the tax penalizes business owners who sell their companies after decades of work, while Chamber President Patrick Woodcock cautioned that higher income taxes could reduce the ability of businesses to reinvest, grow, and hire, especially amid economic uncertainty [1].
Conservative fiscal watchdogs also contend that Maine is moving against the national trend, as many states are currently reducing tax rates to attract new residents [1].
CONCLUSION
Maine’s new millionaire tax is set to raise significant revenue for public programs but has ignited debate over its potential impact on local businesses and economic growth. While supporters highlight the benefits for education and social services, critics warn of negative consequences for entrepreneurship and investment. The market response is mixed, reflecting both optimism for public funding and concern over business competitiveness.
