What Andersen Tax does
Andersen Tax LLC, doing business as Andersen, is a US-headquartered professional services firm providing integrated tax, valuation, transaction advisory, private wealth, and global mobility services to middle-market and large enterprises, family offices, private equity and venture capital funds, high-net-worth individuals, and pre-IPO businesses. The firm was founded in 2002 by 23 former Arthur Andersen partners under the name WTAS, acquired the Andersen brand rights in 2014, and rebranded to simply "Andersen" in 2019. Core products span tax compliance and controversy, US international tax, state and local tax, M&A due diligence, fund formation, business and intangible asset valuation (including QSBS and 409A), outsourced accounting, alternative investment fund services, and wealth transfer and family office advisory. Andersen Global, a Swiss verein, extends the platform to 170 countries through 450 locations and 16,000 professionals, of which 2,000 are partners.
Revenue is generated through custom engagement-based professional services fees with no publicly disclosed pricing tiers, delivered directly by managing directors and partners. The go-to-market relies on enterprise field sales, thought-leadership content (The CFO Series, OBBBA insights, QSBS guides), industry conferences, webinars, and professional referrals rather than third-party distribution. In February 2025, Andersen launched Andersen Consulting globally across 66 countries with 3,000 professionals, integrating business strategy, digital transformation, AI-driven technology solutions, cybersecurity, and sustainability with the firm's tax and legal capabilities; the practice targets $1 billion in revenue within three years.
Andersen Group Inc. completed its IPO on the NYSE on December 16, 2025, under ticker ANDG, raising $176 million at a $1.75 billion valuation and debuting at a 31% premium. FY2025 revenue was $838.7 million (+14.6% YoY), Q1 2026 revenue reached $240.7 million (+15.7% YoY, entirely organic) at a 30% adjusted EBITDA margin (up 250 bps), and full-year 2026 guidance is $980 million to $1 billion. The firm served 10,870 client groups across 18,970 engagements in Q1 2026 and is pursuing acquisitions in Canada, Africa, Latin America, Ireland, New Zealand, and Switzerland.
