Yes, foreigners can establish and own businesses in Korea, subject to the rules for the activity and the person involved. The harder question is what you need to establish.
An overseas brand looking for a Korean distributor, a consultant living in Seoul, and a founder building a technology company may all search for “how to start a business in Korea.” They can need quite different answers. Starting with a registration service before understanding that difference can leave you paying for a structure that solves the wrong problem.
Before you collect documents or transfer capital, work out what the business must do, who will do it, and why it needs a Korean presence.
General information, checked 21 September 2026. This guide is not individual legal, tax or immigration advice. Confirm the requirements for your proposed activity and circumstances with the relevant Korean authority or a qualified Korean professional.
Five questions hidden inside “Can I start a company?”
Ownership concerns who can hold an interest in a business. Incorporation creates a separate company. Business registration registers the activity for tax administration. Foreign-investment recognition applies a further set of statutory conditions. Immigration permission concerns the individual who intends to live and work in Korea.
These processes produce different documents and answer different questions. A company registration certificate cannot settle all of them. Sector-specific licences or approvals may also be needed before the business can operate. The Commercial Act's incorporation rule concerns the creation of the company; tax registration is a separate step with the National Tax Service.
This distinction is useful well before you hire anyone to prepare an application. When an adviser says “you need this,” ask which requirement it satisfies: the company, the tax registration, the investment, the founder's status, or the operating activity.
What would a Korean presence let you do?
Write down the transaction you want to complete. “Enter Korea” is too broad. “Supply three Korean retailers through a local distributor” gives you something to investigate.
Then identify what is missing:
- Customers: Who will buy, and have you spoken to the person with purchasing authority?
- Contracts and payments: Who needs to invoice whom? What do the customer, bank and payment provider actually require?
- People and premises: Will you employ staff, sign a lease, hold stock or need a licensed location?
- Ownership and finance: Are you bringing in partners or raising investment in a Korean entity?
- Your role: Will you manage the business from abroad, relocate, or already have permission to undertake the work in Korea?
A distributor or commercial partner may address an immediate market-entry need. Research and partner discussions may also tell you whether a local operation is justified. Neither option automatically removes Korean tax, licensing or contractual obligations. The point is to compare the actual arrangement before creating an entity by default.
Consider a hypothetical overseas homeware brand. Korean followers ask about its products, and a founder interprets that interest as a reason to open a Seoul company. A more useful first investigation would ask whether retailers want the range, whether customers accept the delivered price, and who will handle importing, returns and local service.
If a suitable distributor will undertake those functions on workable terms, an immediate subsidiary may add little. If buyers require local supply, the brand needs employees, and the founder wants direct control of service and inventory, the case for a Korean operation becomes stronger. The same audience interest can lead to different structures after the commercial work is done.
The main ways to establish a presence
The following distinctions are an orientation. KOTRA's guide to establishing a business explains the formal routes in more detail.
An individual business
An individual business, often called a sole proprietorship, operates through its owner. It is not a separately incorporated company, and the owner carries the business's liabilities personally. It still has business-registration and tax obligations. This can be worth investigating for a person operating alone, provided their immigration status and activity permit it.
A Korean corporation
A corporation is a separate legal entity. It can be useful where ownership, investment, contracts and ongoing operations need to sit within a company. A solo founder can also choose a corporation. The choice is about responsibilities and plans, rather than simply how many people are currently working in the business.
A Korean corporation with foreign-investment recognition
This is a Korean corporation that also satisfies the applicable foreign-investment conditions. “Foreign-invested” describes an investment status. It is not another corporate form alongside a stock company or a limited company. Qualifying foreign investment can also involve an individual business, so the term should not be treated as exclusively corporate.
A branch of an overseas company
A branch can undertake business in Korea as part of an existing foreign company. It is not a separate Korean subsidiary. That relationship matters when considering responsibility for contracts and liabilities.
A liaison office
A liaison office can serve permitted non-sales functions, such as market research and communication. It cannot be used as a substitute for a sales operation that invoices customers and earns business revenue in Korea.

What the KRW 100 million figure actually means
You will encounter KRW 100 million repeatedly in foreign-founder guidance. It does not mean every foreigner must invest that amount to own any Korean corporation.
For the usual equity-investment route under Korea's foreign-investment rules, the investment must be at least KRW 100 million per foreign investor, together with the relevant participation condition. Ordinarily, that means at least 10% of voting shares or total equity. A smaller ownership percentage can qualify where the investor appoints or dispatches an executive with authority to participate in important management decisions. The investment amount remains part of that exception. These conditions appear in the current Foreign Investment Promotion Act Enforcement Decree, Article 2.
KOTRA also explains that a foreigner can establish a Korean corporation below that investment amount without obtaining foreign-investment recognition on that basis. Foreign-exchange or securities-acquisition reporting may still apply. The relevant route depends on the investor and transaction. See the small-investment distinction in Business in Korea 2025.
Treat the threshold as a rule attached to a particular status. It is not a registration fee, a complete startup budget, or a guarantee of immigration permission. Licensed activities can introduce their own requirements as well.
Plan the founder's immigration position at the same time
An overseas shareholder who does not relocate and a shareholder who intends to run the business in Seoul have different personal immigration questions.
Owning the company does not itself establish permission to reside in Korea or work through it. Nor does every foreign founder necessarily need the same D-8 route. Existing status, the proposed work, the business structure and the applicant's role all matter.
Check this before fixing ownership proportions, moving funds or committing to a lease. Our guide to D-8 startup and business visas explains the main distinctions and links to the relevant official guidance.
The registration sequence depends on the route
For a typical new corporation using the foreign-investment route, the work broadly moves through investment notification, documented funding, incorporation, tax registration and foreign-invested-company registration, alongside the required banking and operating arrangements. Some permissions and premises decisions need attention earlier. Other structures follow different procedures.
A practical way to organise that work is:
- Confirm the intended activity and founder's status. Identify sector restrictions, licences, premises conditions and immigration dependencies.
- Choose the structure and ownership. Establish who contributes, who controls decisions and what future investment may require.
- Prepare the documents and funding route. Confirm authentication, translation, remittance and evidence requirements before transferring money.
- Complete the relevant registrations. Distinguish incorporation, tax registration and foreign-investment registration, rather than treating them as one filing.
- Make the operation usable. Complete banking, payment arrangements, accounting, contracts and the permissions needed to begin the intended work.
Banking can be involved at several points, so this is not a rigid five-stage timetable. Document corrections, overseas authentication, an unsuitable address, bank checks or industry approvals can change the sequence and duration.
For tax registration, NTS guidance generally calls for an application before operations begin or within 20 days after business commencement. The reference point is commencement, not simply the date of incorporation. That timing does not remove any obligation to obtain operating permission first.
Budget for running the business
A registration quote tells you little about the cash needed to operate.
Separate professional and administrative fees from invested capital, premises deposits, equipment and operating runway. Then ask who will handle bookkeeping, invoices, VAT where applicable, payroll withholding and tax filings. Hiring also raises employment and social-insurance questions that depend on the workforce and applicable rules.
An NTS explanation of withholding is a useful reminder that paying people creates administration for both individual and corporate businesses. Incorporation does not perform that work for you.
Before choosing a bank or payment service, explain the actual ownership and transaction model and ask for its requirements. Before signing a lease, check that the location can support the intended activity. Before hiring, cost the employment arrangement rather than only the salary.
A better first page than a registration form
Prepare a one-page operating brief: the customer, the problem you solve, what you have tested, the first transaction you want to complete, who will perform the work and which Korean capabilities you need.
Beside each unresolved issue, name the person who can answer it. A prospective customer can explain procurement requirements. A bank can explain onboarding. An immigration authority can address your status. A Korean tax or legal professional can assess the arrangement you actually intend to use.
That turns a vague request to “set up in Korea” into a set of answerable questions. Once those answers support a business model, choosing and registering the structure becomes a much more useful investment.
