What sax does

SAX is a privately held professional services firm headquartered in Parsippany, New Jersey, founded in 1956 and operating as an alternative practice structure comprising Sax LLP (a licensed independent CPA firm providing attest services) and Sax Advisory Group LLC (providing tax and business consulting services). The firm offers an integrated portfolio spanning accounting and auditing, tax (federal, state and local, international, and controversy), business advisory, technology advisory (cybersecurity and managed IT through Sax Technology Advisors), wealth management (SAX Wealth Advisors), investment banking and transaction advisory (SAX Capital Advisors), valuation and forensic/litigation services, and HR consulting. Services are delivered through seven U.S. offices in New Jersey, New York, and Massachusetts, an international office in Mumbai, India, and a remote workforce spanning 25 U.S. states, with a Hubsync client portal supporting secure document exchange.

The firm serves closely held companies, family-owned businesses, nonprofit organizations, and high-net-worth individuals across eight specialized industry verticals: Construction, Consumer and Industrial Products & Services, Real Estate, Nonprofit, Healthcare, Professional Services, Financial Services, and Cannabis. Its go-to-market is relationship-driven, direct professional engagement; service fees are not publicly disclosed and are determined by engagement scope and complexity. Education and thought leadership — including tax alerts, webinars, podcasts (Nonprofit Fundamentals, Herb on the Curb, Good Morning Cannabis, Healthcare Industry Vitals), and industry conferences — function as top-of-funnel marketing.

Under CEO Joseph Damiano (since 2015), SAX has scaled revenue from approximately $25 million to $175 million and grown to 70 partners and 363 employees. In July 2025, the firm received a minority investment from Cobepa (Brussels/New York), an independent investment firm managing approximately $5.3 billion in equity capital, to fund expansion and acquisitions while remaining independent. SAX subsequently acquired Maddaloni, Nydick & Keenan, P.C. in November 2025 — its first post-investment transaction. The firm is nationally ranked (#67 on INSIDE Public Accounting's Top 100, up three spots year-over-year and sixth consecutive year on the list; #21 on Construction Executive's Top 50 Construction Accounting Firms, sixth consecutive year in the Top 25) and recognized as a Top 5 Best of the Best firm in the Northeast region by INSIDE Public Accounting.
