Frequently Asked Questions
How does Massachusetts' millionaire's tax work?
Massachusetts imposes an additional 4% tax on annual income over $1 million, bringing the total rate to 9% for high earners. This applies to all types of income including wages, business income, and capital gains. The threshold is adjusted annually for inflation.
Why are capital gains taxed differently in Massachusetts?
Massachusetts has separate tax rates for capital gains: 12% for short-term gains (held less than one year) and 5% for long-term gains (held more than one year). This creates opportunities for tax planning through timing of investment sales.
What is the Massachusetts rental deduction?
Massachusetts allows a deduction of up to $3,000 for rent paid by tenants to landlords in Massachusetts. This deduction helps offset the cost of housing and is available to both residents and part-year residents who pay rent in the state.
Should I consider relocating from Massachusetts for tax savings?
Tax relocation decisions should consider your total tax situation. While neighboring New Hampshire has no income tax, Massachusetts offers many advantages including strong infrastructure, education, and job opportunities. High earners subject to the millionaire's tax may see significant savings from relocation.
