Larson Gross

What Larson Gross does

Larson Gross is a privately held, full-service accounting and consulting firm headquartered in Bellingham, Washington, founded in 1949 by Ted Larson and Dennis Gross. The firm operates through an alternative practice structure comprising Larson Gross Assurance PLLC (attest services) and Larson Gross Advisors LLC (tax and consulting), delivering six core service lines: Financial Statements (audit, review, compilation, employee benefit plan audits), Tax (individual, business, SALT, e-commerce, U.S.-Canada cross-border), Client Accounting & Advisory Services (CAAS), Business Advisory (valuation, M&A support, board facilitation), Personal Financial Advisory (estate planning, wealth management via Freestone Capital), and Technology Services through subsidiary LGIT Solutions (managed IT, business intelligence, Microsoft 365).

The firm maintains 200+ professionals and 16 partners across five Washington State offices — Bellingham, Burlington, Lynden, Yakima, and Wenatchee — supplemented by a globally distributed remote workforce. Its go-to-market is relationship-led and vertical-specialized, with deep concentration in agriculture, construction, nonprofit, professional services, captive insurance, and U.S.-Canada cross-border tax, serving closely held businesses and high-net-worth individuals with multilingual capabilities spanning Mandarin, Cantonese, Vietnamese, Japanese, and Korean.

Pricing is quote-based across most engagements; individual Form 1040 engagements start at $1,300. In 2026, a majority stake was acquired by Current, a subsidiary of Thrive Holdings, as part of a $1 billion AI-powered accounting roll-up strategy; Current provides an OpenAI-built Tax AI platform that Larson Gross will leverage to automate compliance and advisory workflows. The firm's strategic direction is now shaped by its parent's platform play while maintaining day-to-day operational independence.
