Anchin, Block & Anchin LLP

What Anchin, Block & Anchin LLP does

Anchin, Block & Anchin LLP is a New York-headquartered full-service accounting, tax, and advisory firm founded in 1923 by David Anchin, Max Block, and Max Anchin. With approximately 600 professionals including 70+ partners, principals, and managing directors, the firm serves three primary client segments: privately held businesses (particularly middle-market and emerging companies), investment funds (private equity, hedge funds, real estate vehicles, emerging managers), and high-net-worth individuals and families. The firm operates from four U.S. offices — New York City (3 Times Square headquarters since October 2023), Uniondale on Long Island (opened 2021), Boca Raton, and Palm Beach Gardens (opened 2022) — plus India operations, and maintains global reach through its BKR International membership spanning 160+ firms across 500+ offices in 80+ countries.

The firm's service portfolio is organized around four pillars: Tax Advisory (federal/state/local/international, credits & incentives, R&D, tax controversy), Assurance & Financial Reporting (audit, attest, GAAP readiness), Advisory Services (transaction advisory, valuation, litigation support, regulatory compliance, Client Accounting Advisory Services, technology & data advisory, succession planning via AnchinNEXT), and Private Client Services (estate planning, family office, art collection management, philanthropy). Deep industry specialization across 19+ verticals — including real estate, financial services, architecture/engineering/construction, consumer products, private equity, life sciences, and law firms — is a defining feature, with dedicated partner-level practice leaders for each sector (e.g., Paul Gevertzman and Frederick Ackerman for A/E/C, Robert Gilman for Real Estate, E. George Teixeira for Financial Services).

Revenue mechanics are based on custom engagement-based pricing tied to scope, complexity, and professional time, with no publicly disclosed pricing or financials. Distribution is direct partner-led, supplemented by referral networks from legal advisors, investment bankers, and other professional service firms. The firm has been recognized as a Top 100 Firm by Accounting Today for 2022-2026, with consecutive Best Place to Work recognitions since 2007 and a Net Promoter Score of 83.2% — well above industry averages. In June 2026, Baker Tilly agreed to acquire the firm (closing expected summer 2026), making NYC Baker Tilly's new headquarters and positioning Russell B. Shinsky as Baker Tilly's New York managing principal.

Broad incumbents

• RSM US: Top-5 US accounting firm with a dedicated middle-market strategy and practice mix (private equity, financial services, real estate) directly overlapping with Anchin's primary verticals. Competes head-to-head for middle-market engagements where RSM's larger scale is a differentiator.
• Grant Thornton: Top-6 global accounting firm with a strong middle-market focus and comparable industry verticals (real estate, financial services, private equity). Competes for the largest Anchin-engagement-level opportunities where the Grant Thornton platform provides global reach Anchin lacks.
• BDO USA: Top-5 global accounting network with significant US mid-market presence. BDO competes in many of the same verticals (financial services, real estate, A/E/C, private equity) and is a partial substitute particularly for larger engagements where BDO's national footprint offers scale Anchin alone cannot match.

Closely comparable to Anchin in scale, target market, and partner-led delivery model, and a frequent co-peer on industry awards lists.
• Citrin Cooperman: NYC-headquartered mid-market accounting and advisory firm with very similar private business, real estate, and financial services practice mix. Direct competitor in the NY metro middle market with comparable size and partner-led service model.
• EisnerAmper: Top-30 US accounting firm headquartered in NYC with deep practices in financial services, real estate, and private equity fund accounting—directly overlapping with Anchin's three largest verticals.
