The 50 largest accounting firms in California (2026 list)

The accounting firms in California are primarily mid-sized and large firms, with a focus on comprehensive financial services. Many offer a range of accounting, tax, and consulting solutions, catering to diverse industries. For example, Andersen provides global accounting and tax services, Armanino offers CPA and consulting services, and BPM LLP is a top public accounting firm recognized for growth. GHJ is an advisory and accounting firm serving nonprofit, food and beverage, and entertainment sectors. CCG specializes in tax credit consulting, while Novogradac focuses on real estate and affordable housing.

A clear pattern among these firms is the concentration of headquarters in major Californian cities. San Francisco, Los Angeles, and the surrounding Bay Area are prominent locations, indicating a regional hub for financial and accounting expertise. The founding dates span several decades, with many firms established in the mid-to-late 20th century, such as Armanino (1969) and Frank, Rimerman + Co. LLP (1949), alongside more recent establishments like Scrubbed (2012).

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
