Profitable Massachusetts businesses paying more tax than they should
Massachusetts tax planning often focuses on the millionaire’s surtax, the pass-through entity excise and timing major income events. We model business sales, bonuses and distributions so the surtax does not catch you off guard.
Massachusetts is a center for biotech, life sciences, higher education, finance and technology, with business activity concentrated around Boston, Cambridge, Worcester and Springfield. Business owners face a flat state income tax, an additional surtax on very high incomes and corporate excise tax. NexusWorks helps Massachusetts businesses plan and stay compliant.

We serve Massachusetts biotech and life sciences companies, technology startups, investment and financial firms, healthcare practices and education-related businesses in Boston, Cambridge and Worcester.

Corporations pay the Massachusetts corporate excise tax, individuals pay state income tax on pass-through profits, and most retail sales are subject to sales tax. Massachusetts also offers an elective pass-through entity excise. We coordinate these filings for you.
