Accounting & Tax Acquisitions in Massachusetts

Massachusetts Accounting & Tax Deals

Massachusetts has seen steady deal activity across accounting and tax services, ranging from regional CPA roll-ups to platform build-outs backed by private equity. Recent transactions include acquisitions and growth investments tied to expanding audit, tax, advisory, valuation, and specialty practices.

Across the listed Massachusetts deals, recurring buyer types include established CPA and advisory firms (for example AAFCPAs, Cherry Bekaert, Aprio, Citrin Cooperman, and Mazars USA LLP) and growth platforms such as Earned and private equity-backed operators. Several deals also target expansion into specific Northeast or Boston-area markets and add capability depth—such as forensic accounting and litigation support, outsourced accounting for government contractors, healthcare practice services, and managed SEC or valuation offerings.

The page also reflects how capital and expertise move together in this industry: private equity funds and operators (including CVC Capital Partners, Carlyle, Kelso & Company, and Everlane Equity Partners) support scaling strategies, while targeted acquisitions bring in partner and professional teams to strengthen local presence and service breadth.

  • AAFCPAs acquired McLaren & Associates CPAs, PC to expand forensic accounting, litigation support, business valuation, and tax advisory capabilities.
  • Cherry Bekaert completed multiple Massachusetts-area acquisitions, including Jameson & Company CPAs and Katz Nannis + Solomon, strengthening audit, tax, and advisory presence in the Northeast.
  • Specialty service themes appear repeatedly: outsourced accounting for small federal government contractors, healthcare-focused tax and practice services, and property tax consulting.
  • Partner-and-team integration is a consistent deal feature, with acquirers bringing over managing partners and professional staff to deepen local capability.
