We provide integrated back-office support for foreign-owned companies operating in Korea — foreign-invested companies, branch offices and liaison offices — covering tax, accounting and administrative matters as a single, coordinated function.
Many operational issues arise not at the filing stage, but earlier — when licensing, regulatory requirements, and corporate structures are handled separately.
As licensed tax accountants and administrative agents, we manage these processes together to reduce delays, compliance risks, and unnecessary operational burdens.
Our services are designed for companies that need a reliable back-office structure in Korea, rather than fragmented support from multiple providers.

Tax accountant + administrative agent — one office
Single Point of Contact
Tax compliance, payroll, licensing, and corporate governance are managed together. No coordination required between separate providers for overlapping obligations.
Sector-Specific Experience
Foreign-invested companies, branch offices, and liaison offices each carry distinct compliance profiles. We structure our support to match the actual obligations of each entity type.
Integrated Back-Office
From tax invoice management to board meeting procedures — all back-office functions handled as a single, coordinated process rather than isolated tasks.
