Most guides describe Korea business registration as a single process. That is the first thing to correct, because it is where most foreign companies lose time.
Korea business registration produces two separate documents from two separate authorities. The corporate registration certificate comes from the local district court’s commercial registry and establishes the company’s legal existence. The business registration certificate (사업자등록증) comes from the National Tax Service and establishes its tax identity. You need both. Companies that assume registration means one filing routinely discover the second requirement at the point it starts costing them money.
This guide covers the full sequence: which entity type to choose, the investment threshold that determines your regulatory path, the documents your parent company must produce, realistic timelines, costs, and the mistakes that most often delay an otherwise clean registration.
Who needs to complete Korea business registration
Any foreign company intending to generate revenue in Korea, sign contracts under a Korean entity, or employ staff locally must register. There is no informal threshold below which this becomes optional.
The one genuine exception is a liaison office, which may carry out market research, liaison, and support work for the foreign parent but cannot invoice or generate revenue in Korea. It suits a real exploratory phase and becomes unsuitable the moment commercial activity begins.
The four structures, and what actually separates them
Yuhan Hoesa (유한회사) — private limited company
The most common choice for foreign investors. No statutory minimum capital under the Commercial Act, simpler governance, and shareholder liability limited to the investment. Suits SMEs, startups, and first-time entrants.
Jusik Hoesa (주식회사) — joint stock company
The Korean equivalent of a corporation. Heavier disclosure and governance obligations, including board and auditor requirements at certain thresholds. Appropriate for larger operations, joint ventures, or any company contemplating a future Korean listing or external capital raise.
Branch office
An extension of the foreign parent rather than a separate legal entity. It can trade and invoice, but the parent carries full legal liability for the branch’s obligations, and a branch generally cannot qualify as a foreign-invested company for incentive purposes. We compare the two in detail in our guide to branch office versus subsidiary in Korea.
Liaison office
Non-revenue activity only, as above.
The decision that matters most: if government incentives, cash grants, or tax reductions form any part of your Korea plan, the structure choice effectively makes itself. Incentive programmes are built around the foreign-invested company, which requires a Korean entity holding formally notified foreign investment. A branch does not create one.
The KRW 100 million threshold, and why it changes your path
This is the single most consequential number in Korean business registration, and it is widely misunderstood.
Under Article 2(3) of the Enforcement Decree of the Foreign Investment Promotion Act (FIPA), an investment qualifies as foreign direct investment where a foreigner invests not less than KRW 100 million and acquires 10 percent or more of the voting shares. Where two or more foreign investors invest jointly and the combined total reaches the threshold, it can still be recognised as FDI.
Above the threshold. Your Korean entity can be registered as a foreign-invested company. This unlocks eligibility for incentive programmes, provides the basis for the D-8 corporate investment visa, and brings the protections of the FIPA framework.
Below the threshold. You can still establish a Korean corporation — the Commercial Act and the foreign investment framework are separate regimes, and incorporation is not blocked. What changes is that the investment is not recognised as foreign direct investment. It falls instead under stock acquisition notification rules in the Foreign Exchange Transactions Act, and the incentive and visa routes that depend on foreign-invested company status are not available.
The practical point: KRW 100 million is a structuring decision, not a budgeting one. Deciding it after registration is considerably more expensive than deciding it before.
The registration sequence
- Name reservation with the commercial registry, confirming the proposed name is available and permissible.
- Foreign investment notification, filed through a designated foreign exchange bank or KOTRA, where the investment meets the FDI threshold.
- Capital remittance into a temporary Korean account, documented to evidence the investment.
- Corporate registration with the local district court’s commercial registry, producing the corporate registration certificate and corporate registration number.
- Business registration with the National Tax Service, producing the business registration certificate and corporate tax ID.
- Foreign-invested company registration, where applicable, completing FIPA status.
- Post-registration setup: corporate bank account, VAT registration, and the four major insurances once staff are hired.
Step 5 carries its own deadline: business registration must be completed with the district tax office within 20 days of commencing business. Our guide to Korea post-registration deadlines maps the full first-year compliance calendar.
Realistic timelines
Published estimates vary widely, usually because they measure different things.
- The US State Department’s Investment Climate Statement notes that for SMEs with assets below KRW 1 billion, the online business registration step takes roughly three to seven days, completed through Korean-language systems.
- For a full foreign-invested company registration including notification, remittance, court registration, and tax registration, three to six weeks is a more realistic end-to-end expectation.
The variable that most often stretches this is not Korean processing time. It is document preparation in the parent company’s home jurisdiction.
Documents from the foreign parent
- Certificate of incorporation or equivalent registry extract for the parent company
- Articles of association
- Board resolution authorising the Korean establishment
- Certified passport copies or identification for shareholders and directors
- Proof of the Korean registered address
- Power of attorney where a local representative will file
These generally require notarisation and apostille in the home jurisdiction. Where the parent’s country is not party to the Apostille Convention, consular legalisation applies instead and takes longer. This is the most common cause of timeline slippage, and it is entirely avoidable by starting the document chain before the Korean steps begin.
What registration costs
| Category | What it covers |
|---|---|
| Government fees | Registration tax, local education tax, court filing fees |
| Capital | The investment itself — KRW 100 million where FDI status is sought |
| Professional fees | Legal, accounting and filing support; translation and certified documents |
| Ongoing | Corporate tax filings, VAT returns, payroll and insurances, annual reporting |
Registration tax is calculated on capital and varies by region, with higher rates in designated over-concentration control areas around Seoul. For a line-by-line breakdown, see our Korea company registration cost guide.
Directors, shareholders, and foreign ownership
Korean corporate law permits complete foreign ownership and foreign directorship. There is no requirement to appoint a Korean national or resident director for a standard company.
At least one director is required. Where more than one is appointed, a representative director must be designated to act for the company in legal and administrative matters.
A limited number of business categories carry foreign ownership restrictions or partner requirements, set out in the FIPA framework and its enforcement decree. Confirm these against your intended business classification before committing to a structure.
Six mistakes that delay registration
- Treating registration as one filing. Two certificates, two authorities.
- Leaving apostille to the end. Parent documents are the long pole; start them first.
- Deciding the investment amount after choosing the structure. The KRW 100 million line determines the regulatory path, so it comes first.
- Choosing a branch for speed, then wanting incentives. Branches generally fall outside the foreign-invested company framework.
- Using a liaison office commercially. It cannot invoice. Doing so creates a compliance problem, not a shortcut.
- Misclassifying the business category. Classification affects restrictions and incentive eligibility, and is difficult to change afterwards.

Frequently asked questions
What is the difference between corporate registration and business registration in Korea?
Corporate registration is filed with the local district court’s commercial registry and establishes the company’s legal existence. Business registration is filed with the National Tax Service and establishes its tax identity, producing the business registration certificate. Both are required, and they are separate filings with separate authorities.
Do I need KRW 100 million to register a company in Korea?
No. You can incorporate a Korean company below that amount. However, under Article 2(3) of the FIPA Enforcement Decree, an investment of not less than KRW 100 million with 10 percent or more of voting shares is what qualifies as foreign direct investment. Below it, the investment falls under Foreign Exchange Transactions Act notification rules, and foreign-invested company status with its incentive and D-8 visa implications is not available.
How long does Korea business registration take?
For SMEs, the online business registration step can take roughly three to seven days. A full foreign-invested company registration including notification, remittance, court registration and tax registration more realistically takes three to six weeks. Preparing apostilled parent company documents is usually the longest element.
Can a foreigner own 100 percent of a Korean company?
Yes. Korean corporate law permits full foreign ownership and foreign directorship, with no requirement for a Korean national or resident director in a standard company. A limited number of business categories carry ownership restrictions.
Which entity type should a foreign company choose?
Most first-time entrants choose a Yuhan Hoesa for its simpler governance and absence of minimum capital under the Commercial Act. A Jusik Hoesa suits larger operations or those planning external capital. A branch avoids creating a separate entity but leaves the parent fully liable and generally outside the incentive framework.
Do I need to visit Korea to register a company?
Not necessarily. Much of the process can be completed through a local representative acting under power of attorney, though specific steps such as opening a corporate bank account may require attendance depending on the institution.
