Massachusetts Millionaire Tax: Why High Earners Choose Florida

For Massachusetts households with substantial income, the state’s “millionaire tax” has become an important factor in long-term financial and lifestyle planning. Approved by voters in November 2022 and effective beginning with the 2023 tax year, the measure adds a 4% surtax to Massachusetts taxable income above an annually inflation-adjusted threshold that began at $1 million. In practical terms, a taxpayer with $2 million of taxable income could face approximately $40,000 in additional Massachusetts income tax on the $1 million above the threshold, before considering other deductions, credits, and filing details.

The policy was designed to generate funding for education and transportation, and it has produced significant revenue. Massachusetts reported nearly $2.99 billion in estimated fiscal-year 2025 collections from the additional 4% tax, illustrating the scale of the measure and why it is receiving close attention from business owners, investors, executives, retirees, and households with large capital gains.

For many high earners, the issue is not simply the tax on salary. Massachusetts taxable income can include compensation, investment income, business income, and capital gains, depending on the taxpayer’s circumstances. A liquidity event, sale of a company, concentrated stock position, or significant real estate transaction can potentially push income above the surtax threshold in a single year. That makes tax planning especially relevant for entrepreneurs and executives whose income fluctuates substantially.

Florida stands out because it does not impose a state personal income tax. The Florida Department of Revenue confirms that individuals generally do not file a Florida personal income tax return, although residents still encounter other taxes, including property taxes, sales taxes, insurance costs, and local assessments. ([floridarevenue.com](https://floridarevenue.com/faq/Pages/FAQDetails.aspx?FAQID=1466)) The potential difference is meaningful: a Florida resident may avoid the state-level income tax that would otherwise apply to wages, investment income, or certain realized gains, subject to federal tax rules and the individual’s complete tax profile.

That potential savings is one reason Florida remains a leading destination for interstate migration. IRS-based analysis cited by the Tax Foundation found that Florida recorded a net gain of 125,551 income tax filers from interstate migration between 2021 and 2022, while Massachusetts experienced a net loss of 26,033. Migration is never driven by one factor alone, but taxes can influence decisions alongside climate, business conditions, housing, healthcare, family considerations, and the ability to work remotely.

Delray Beach is particularly attractive to Massachusetts buyers seeking more than a lower-tax environment. The area offers an established coastal lifestyle, walkable downtown amenities, cultural venues, marinas, golf, private clubs, and access to Palm Beach International Airport. Buyers can choose among oceanfront condominiums, gated communities, golf-course residences, estate properties, and waterfront homes in Delray Beach, depending on their priorities and budget. For those comparing East Coast Florida real estate markets, Delray Beach combines sophistication with a more relaxed residential atmosphere.

Relocating for tax reasons requires more than purchasing a Florida home. Establishing Florida domicile may involve changing a driver’s license, voter registration, mailing address, professional records, and day-to-day living patterns. Individuals should also document the timing and substance of their move and consult qualified tax and legal professionals before selling assets or changing residency. A second home alone does not automatically end Massachusetts residency obligations.

For high-net-worth buyers considering a move, the best approach is to evaluate taxes, real estate, lifestyle, and long-term wealth planning together.
