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.
Led by a licensed tax accountant who is also a licensed administrative agent, 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
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.
