1. Massachusetts LLC Overview

If you operate a business in Massachusetts, you generally must form your LLC there. The state offers a massive, highly-educated workforce, particularly in tech and healthcare, but it comes with a premium price tag.

  • Highest state fees — $500 to form, $500 every year
  • Flat income tax — 5% rate on personal income (plus a surtax on high earners)
  • No franchise tax — Standard LLCs don't pay a corporate franchise tax
The Most Expensive LLC in America

Before forming an LLC in Massachusetts, ensure your business revenue can support a mandatory $500 state fee every single year. For freelancers or side-hustles, a sole proprietorship might be a more cost-effective choice until revenue increases.
