Foreign companies entering Korea face one unavoidable first step: Korea business registration. Without it, you cannot open a corporate bank account, hire staff, invoice clients, or operate legally in the country. Yet the process trips up more companies than it should, mostly because the paperwork requirements differ depending on entity type and nationality of the parent company.
This guide breaks down what Korea business registration actually involves, which structure fits your situation, and where foreign companies most often lose time.
Korea business registration is the legal process of formally establishing a company or branch with Korean authorities. It results in two core documents: a corporate registration certificate (issued by the local court registry) and a business registration certificate (issued by the National Tax Service). Both are required before you can transact commercially in Korea.
The corporate registration number identifies your entity in the Korean Commercial Registry. The business registration certificate is what banks, landlords, and government offices will ask for repeatedly, so getting it right the first time matters.

Any foreign company planning to hire locally, sign contracts under a Korean entity, or generate revenue inside Korea needs to complete business registration. This applies whether you're opening a small representative presence or a full subsidiary.
Companies that only need market research or liaison functions, without commercial activity, may qualify for a representative office instead of full registration. Everyone else needs to register.
Branch Office
A branch operates as an extension of the foreign parent company. It can generate revenue and sign contracts, but the parent company carries full legal liability for the branch's obligations.
Subsidiary (LLC or Corporation)
A subsidiary is a separate Korean legal entity, most commonly structured as a Yuhan Hoesa (유한회사, similar to an LLC) or Chusik Hoesa (주식회사, similar to a corporation). Liability is limited to the Korean entity, which is why most foreign companies choose this route.
Representative Office
A representative office cannot generate revenue in Korea. It exists purely for market research, liaison, or non-commercial activity, and it is the lightest registration option available.
Each step depends on the one before it, so a missing apostille or an incomplete document set at step 2 delays everything downstream.
Working through document prep right now? Our team at Pearson & Partners Korea handles apostille coordination and registry filing so nothing stalls the process.
Typical requirements include:
Requirements can shift slightly by industry, so companies in regulated sectors (finance, healthcare, telecom) should expect additional documentation.
Korea business registration timelines vary based on entity type, how quickly apostilled documents arrive, and whether the local court registry has a backlog. Branch and representative office registrations tend to move faster than full subsidiary formation, since subsidiary setup involves additional capital deposit and shareholder documentation steps.
Government filing fees are modest. The larger cost driver is usually professional fees for translation, apostille coordination, and registered agent services, which vary by provider and entity complexity.
Beyond registration itself, most foreign companies need ongoing support: payroll, the four mandatory social insurances, tax filing, and D-8 visa sponsorship for expatriate staff. Pearson & Partners Korea handles the full lifecycle, from initial registration through Employer of Record (EOR) services for companies not ready to run full local HR and payroll themselves.

Organizations like KOTRA and the World Bank publish general guidance on doing business in Korea, and both are useful starting points for foreign investors researching the broader regulatory landscape before registration.
How long does Korea business registration take?
Timelines depend on entity type and how quickly home-country documents are apostilled. Branch and representative office registrations generally move faster than subsidiary formation.
Can a foreign company own 100% of a Korean subsidiary?
Yes, in most industries. Certain regulated sectors carry foreign ownership restrictions, so it's worth confirming your industry's status before choosing a structure.
Do I need a Korean bank account before registering?
You need a temporary account to deposit capital during registration, then a permanent corporate account once your business registration certificate is issued.
What's the difference between corporate registration and business registration?
Corporate registration (court registry) establishes your legal entity. Business registration (tax office) is what allows you to operate commercially, issue invoices, and pay taxes.
