Massachusetts Millionaire’s Tax

On Election Day, November 8th, Massachusetts voters approved Question 1 to amend the state constitution and establish an additional 4% surtax on taxable income in excess of $1 million dollars.

Millionaire’s Tax Facts

  1. This additional income tax will be effective for tax years beginning January 1, 2023, which will be reported on returns due in April 2024.
  2. The $1,000,000 taxable income threshold will be adjusted annually for inflation using the same method that the IRS follows.
  3. Only the taxable income that exceeds $1,000,000 is subject to the additional 4%. For example, if your Massachusetts taxable income is $1,500,000 then $1,000,000 will be subject to tax at 5% and $500,000 will be subject to tax at 9%.
  4. This is a tax on income and not the value of a particular asset. So, if your 401(k) or IRA has a value over $1,000,000 this does not matter unless your annual distribution exceeds this amount.
  5. Similarly, only the taxable gain from the sale of a home or business would be subject to this tax, and not the gross selling price.

We expect more information from the Department of Revenue in the coming weeks.
