What Deloitte Korea does

Deloitte Korea is a member firm of the global Deloitte network (Deloitte Touche Tohmatsu Limited, or DTTL) operating in South Korea, structured around two core affiliates: Deloitte Anjin (audit and assurance) and Deloitte Consulting Korea (consulting). The firm provides professional services across four primary revenue streams: audit and assurance, tax advisory, consulting (including strategy, digital transformation, and AI integration), and marketing and communications consulting. The marketing and communications capability was added through the June 2022 acquisition of PRGATE, a local communications firm that brought approximately 60 staff and expertise in brand strategy and digital publicity into Deloitte Korea's operations.

The firm's service delivery is increasingly anchored on proprietary AI platforms deployed for audit and accounting automation, including Halo, Clara, Canvas, and Omnia, which collectively reduce audit standard input time by more than 20%. Beyond tool deployment, Deloitte Korea is positioning itself as an advisory authority on agentic AI and AI governance, citing industry survey findings that 74% of companies plan to utilize agentic AI above average levels within two years and that AI introduction in Korean finance, accounting, and audit functions rose from 17% to 28% year-over-year. The firm is headquartered in Seoul and serves large Korean enterprises, corporate boards, and companies pursuing international capital market listings.

Deloitte Korea operates on a professional services engagement model with quote-based pricing, an enterprise field sales motion led by the CEO and senior partners, and a horizontal segmentation approach targeting large corporations as the primary customer base. Under incoming CEO Kil Ki-wan (beginning a four-year term in May 2026), the firm is executing a two-pillared strategy: reinforcing core audit and tax advisory operations while expanding consulting capabilities, supported by an eight-member executive team that includes the first woman to lead one of the group's main business divisions.
