The back office for foreign
companies in Korea that have
no finance staff here.
Yoon Tax & Administrative Office provides outsourced bookkeeping, accounting, payroll and tax filing services for foreign-owned companies operating in South Korea, with service delivered in English. We work with foreign-invested companies, branch and liaison offices — usually those with no finance or HR staff of their own here. Tax compliance, payroll, licensing and corporate governance are handled as one function, not split across separate providers.
One specific client profile: foreign-owned companies running operations in Korea without a finance team of their own.
Most operational problems for foreign businesses in Korea do not start at the filing stage — they start earlier, when a company works with separate providers for tax, payroll, licensing, and legal matters and no one is looking at the whole picture.
That is the shape of company we are built for: a Korean entity with obligations in Korean, and no one on the payroll here whose job it is to meet them. If what you need is payroll processing alone, or an Employer of Record so you can hire in Korea without an entity, this is not the office for that. Start with the structure closest to yours below, or read about our practice and credentials.
Choosing the right structure for Korea operations
The appropriate structure depends not only on business plans, but also on licensing requirements, tax exposure, staffing plans, and visa considerations. Full comparison and requirements are on the Foreign Investment page.
Foreign-Invested Company (FIC)
Separate Korean legal entity with full compliance obligations
A foreign-invested company is the most common structure for foreign businesses planning long-term operations in South Korea.
Branch Office
Extension of a foreign company — not a separate legal entity
A branch office is an extension of a foreign company and does not constitute a separate legal entity in South Korea.
Liaison Office
Non-revenue activities only — market research and communication
A liaison office is designed for non-revenue-generating activities such as market research and communication.
Ongoing compliance and back-office obligations in Korea
Operating a business in Korea involves a set of ongoing tax, payroll, and administrative obligations. These apply regardless of company size once business activities begin.
