How to Register a Company in South Korea, Step‑by‑step (foreign Investors, 2026)

Understanding how to register a company in South Korea is the essential first step for any foreign founder, multinational subsidiary or international investor looking to establish a local presence in one of Asia’s largest economies. The process involves a defined sequence, foreign investment notification (FDI declaration), capital remittance, incorporation at the Commercial Registry, business registration with the National Tax Service (NTS), and post‑incorporation compliance including payroll and social insurance enrolment. South Korea permits 100 per cent foreign ownership in most sectors, and the procedural framework is administered primarily through InvestKOREA, the district courts and the NTS.

In 2026, renewed administrative emphasis on FDI notification compliance and streamlined business‑opening procedures make it particularly important for foreign investors to follow each step precisely and in the correct order.

Overview of the registration process and who it applies to

Foreign investors entering South Korea typically choose one of three entity structures: a Jusik Hoesa (stock corporation, comparable to a limited company), a Yuhan Hoesa (private limited company), or a branch office of an existing foreign entity. The Jusik Hoesa is the most common vehicle for foreign‑invested companies and is the default structure described by InvestKOREA’s official guidance. A Yuhan Hoesa offers a simpler governance structure and is often preferred by smaller operations. A branch office does not create a separate Korean legal entity, instead it extends the foreign parent’s legal personality into Korea, with different tax and liability implications.

Foreigners may wholly own a Korean company. There is no requirement for a local shareholder. Foreign nationals may also serve as directors and as the company’s representative, although practical considerations around visa status and physical presence for banking and court filings can complicate matters. Industry observers note that most foreign founders appoint a locally resident representative or engage local counsel to handle in‑person filings at the district court and tax office.

Regardless of entity type, any investment meeting the threshold for a foreign‑invested company must be preceded by a foreign investment notification filed with a designated foreign exchange bank or InvestKOREA. This notification is the gating action that unlocks the formal incorporation workflow described in the steps below.

Eligibility and prerequisites for how to register a company in South Korea

Entity choice: Jusik Hoesa vs Yuhan Hoesa vs branch

The choice of entity has consequences for governance, capital requirements, reporting obligations and tax treatment. A Jusik Hoesa requires at least one director and is subject to external audit thresholds. A Yuhan Hoesa has a lighter governance burden and no statutory audit requirement below certain asset thresholds. A branch office files tax returns in Korea but its liabilities flow back to the foreign parent. Most foreign investors forming a new standalone Korean operation choose the Jusik Hoesa because it is the entity type referenced throughout InvestKOREA and KOTRA guidance, and because Korean counterparties, banks and government agencies are most familiar with this structure.

Minimum investment and FDI recognition

To be formally recognised as a foreign‑invested company under Korea’s Foreign Investment Promotion Act (FIPA), the foreign investor must acquire shares or equity stakes worth at least KRW 100,000,000 (approximately USD 75,000) and hold at least 10 per cent of the voting shares, according to guidance published by Hawksford and InvestKOREA. Meeting this threshold is not a legal prerequisite for incorporation itself, a foreigner may incorporate a Korean company with less capital, but it is required to access FDI incentives, tax benefits and the formal foreign‑invested company registration administered by InvestKOREA. Investors should confirm the applicable threshold with InvestKOREA, as certain sectors and incentive programmes may set different requirements.

Director, representative and visa considerations

At least one director must be appointed. There is no Korean nationality or residency requirement for directors, but the company’s registered representative who handles day‑to‑day filings typically needs to be present in Korea for key steps such as court registration and bank account opening. Foreign founders intending to reside and work in Korea will generally require a D‑8 (corporate investment) visa or equivalent work authorisation. Visa processing runs in parallel with company formation and should be planned from the outset to avoid delays.

Step‑by‑step procedure to register a company in South Korea

Step 1, Plan entity structure, capital and local address

Before filing anything, the founder or adviser should finalise the entity type (Jusik Hoesa, Yuhan Hoesa or branch), determine the share structure and par value, draft the Articles of Association (Jeongwan), identify the initial directors and representative, and secure a Korean office address. A registered address is mandatory for business registration; a virtual office may suffice for initial filing, but some tax offices require a physical lease. Prepare a preliminary capital plan, the total amount to be remitted, and identify the designated foreign exchange bank that will handle the FDI notification and capital transfer.

Step 2, File the foreign investment notification (FDI declaration)

The investor (or an authorised agent) must submit a foreign investment notification to a designated foreign exchange bank or directly through InvestKOREA before or at the time of remitting capital. According to InvestKOREA’s official guidance, the standard sequence is: notify → remit funds → register corporation. The notification form, the Foreign Investment Notification, requires details of the investor, the planned Korean entity, the investment amount and the business activity. Upon acceptance, the bank issues confirmation that the FDI notification has been filed and the capital has been received. This confirmation document is required for subsequent court registration and for completing the foreign‑invested company registration after incorporation.

Step 3, Prepare and notarise incorporation documents

Gather and execute all incorporation documents. Key documents include the Articles of Association (signed by all founders), board resolution or founders’ resolution appointing directors and the representative, passport copies of all founders and directors, and a power of attorney if a local representative or counsel will file on the founders’ behalf. Foreign‑source documents, such as a certificate of incorporation of the parent company, powers of attorney or board resolutions, must typically be notarised and apostilled (for countries party to the Hague Apostille Convention) or consularly legalised (for non‑Hague countries). All foreign‑language documents must be officially translated into Korean, and the translator’s certification should be notarised.

This step is often the longest in the process, particularly for founders based in countries with slower notarisation or apostille turnaround times.

Step 4, Register with the Commercial Registry at the district court

The incorporation application is filed with the competent district court (the court with jurisdiction over the company’s registered address). Local counsel or the appointed representative submits the application together with the Articles of Association, directors’ consents, proof of capital deposit or FDI notification confirmation, and all supporting notarised and translated documents. Upon review and approval, the court issues a Certificate of Registration (Deunggi Sahangjeongseo) confirming the company’s legal existence. Court processing typically takes 3–10 business days, depending on the district and completeness of the application.

Step 5, Register the business with the tax office and obtain a business registration number

Within 20 days of commencing business activities, the company must file a business registration application with the local district tax office or electronically via the NTS Hometax system. The tax office issues a Business Registration Number (Saeopja Deungnok Beonho), which functions as the company’s tax identification number and is required for invoicing, VAT filings, opening bank accounts and virtually all commercial transactions. The application requires the Certificate of Registration from the court, a copy of the lease agreement, the Articles of Association and identification documents for the representative. According to the NTS, this step can often be completed on the same day or within one to three business days.

Step 6, Open a bank account for the foreign company, remit share capital and complete FDI proof

With the Certificate of Registration and Business Registration Number in hand, the company opens a corporate bank account at a Korean commercial bank. The foreign investor then remits the subscribed share capital into this account. The bank issues a capital deposit confirmation (Jupgeum Jeunmyeongseo), which is needed to finalise the foreign‑invested company registration with InvestKOREA. Bank KYC requirements for foreign‑owned companies can be demanding: banks may require in‑person attendance by the representative, certified Korean translations of all corporate documents, and proof of the registered office address. Early engagement with the bank, ideally during Step 1, can reduce delays at this stage.

Step 7, Complete post‑incorporation registrations (tax, payroll and social insurance)

After incorporation and business registration, several mandatory registrations follow. If the company conducts VAT‑able activities, VAT registration is typically handled as part of the business registration application. Corporate tax obligations commence with the first fiscal year. The company must also register as an employer for Korea’s four major social insurance programmes, National Pension, National Health Insurance, Employment Insurance and Industrial Accident Compensation Insurance, before running its first payroll. The employer registration is filed with the National Pension Service and the National Health Insurance Service respectively. Corporate seal registration, while not legally mandatory for all entity types, is standard practice and may be required by banks and counterparties.

Step 8, Maintain ongoing compliance

Once operational, the company must file annual corporate tax returns (within three months of the fiscal year‑end), submit VAT returns (quarterly or semi‑annually depending on the filing period), prepare and file annual financial statements, and comply with any transfer pricing documentation requirements if there are related‑party cross‑border transactions. The company must also maintain its foreign‑invested company registration with InvestKOREA, reporting any material changes to shareholding or investment amounts.

Timeline summary

In straightforward cases, where documents are already apostilled, the investor has a Korean address secured, and bank KYC proceeds smoothly, the end‑to‑end process from FDI notification to completed business registration typically takes 2–4 weeks. Where apostille processing is slow, visa applications run in parallel, or bank KYC raises queries, the timeline can extend to 8 weeks or longer.

Documents needed to register a company in South Korea

Apostille vs consular legalisation

If the investor’s home country is party to the Hague Apostille Convention, foreign‑source documents need only an apostille certificate from the competent authority in the issuing country. If the home country is not a Hague member, documents must be consularly legalised, typically authenticated first by the home country’s foreign affairs ministry, then by the Korean embassy or consulate in that country. South Korea is a Hague Convention member, and Korean authorities accept apostilled documents from all other member states. Always confirm current requirements with the relevant Korean consulate, as practice can vary by document type.

Translation and certification checklist

All documents submitted to Korean courts, tax offices and banks must be in Korean. Prepare certified Korean translations of every foreign‑language document. The translator should provide a signed certification statement confirming the accuracy of the translation. While Korean law does not always require the translator’s certification to be notarised, doing so reduces the risk of rejection by courts or banks. Budget for translation of at least 5–8 documents as a baseline.

Timeline and key deadlines for company registration in South Korea

The indicative project timeline for a straightforward formation looks as follows: Day 0–7, planning, entity selection and FDI notification filing; Day 7–21, document preparation, notarisation, apostille processing and court registration; Day 21–35, bank account opening, capital deposit and post‑incorporation registrations (tax, payroll, social insurance). Founders should build buffer time for apostille processing in their home country, which is the single most common source of delay.

Company registration cost in South Korea, fees and tax considerations

The market estimate of USD 10,000–15,000 for end‑to‑end company registration (including professional fees, government charges and document preparation) is consistent with ranges published by GSL Law & Consulting and other advisory firms active in the Korean market. Actual costs will vary depending on entity complexity, the number of foreign‑source documents requiring apostille and translation, and whether the engagement includes ongoing accounting and payroll setup.

Tax considerations at formation

South Korea’s corporate income tax is levied at progressive rates, with the top marginal rate applying to taxable income above the highest bracket. New companies should confirm the current rate schedule with the NTS or their tax adviser. VAT at 10 per cent applies to most goods and services; companies conducting VAT‑able activities should ensure VAT registration is completed as part of the business registration process. On the payroll side, employers are responsible for withholding income tax from employee salaries and for paying the employer’s share of contributions to the four major social insurance programmes, National Pension, National Health Insurance, Employment Insurance and Industrial Accident Compensation Insurance.

Employer registration for these programmes should be completed before the first payroll run to avoid penalties.

What changes in 2026 for foreign company registration in South Korea

In 2026, early indications suggest that the Korean government has continued its trajectory of administrative simplification for business‑opening procedures, including expanded electronic filing options and streamlined inter‑agency data sharing. Advisory firms such as Pearson Korea and Tetra Consultants have reported that the 2026 environment features renewed regulatory emphasis on the foreign investment notification process, specifically, stricter compliance checks on the timing and completeness of FDI declarations filed before capital remittance. The likely practical effect is that investors who historically filed FDI notifications retroactively or informally now face closer scrutiny and should file before or simultaneously with remitting funds.

InvestKOREA continues to serve as the primary point of contact for foreign investors navigating the registration process. Investors should verify all forms, thresholds and procedural requirements directly with InvestKOREA or KOTRA before filing, as administrative guidance can be updated between legislative cycles. These are administrative clarifications and emphasis items reported in 2026, they do not represent new primary legislation, but they do change the practical compliance posture for foreign founders.

Common pitfalls and how to avoid them

• Missing or incorrect apostilles. Documents apostilled for the wrong jurisdiction, bearing expired apostille certificates or lacking certified Korean translations are the single most common cause of court rejection. Verify requirements with the Korean consulate in the relevant country and prepare apostilles well in advance.
• FDI notification timing errors. Filing the foreign investment notification after capital has already been remitted, or failing to file at all, can result in administrative penalties and complications with the foreign‑invested company registration. File the notification before or simultaneously with remitting funds, and retain the bank’s FDI confirmation document.
• Bank account and KYC delays. Korean banks apply rigorous KYC procedures to foreign‑owned companies. Delays are common when the authorised signatory is not physically present in Korea, when corporate documents are not fully translated, or when the company’s registered address cannot be verified. Engage the bank early, ideally during the planning phase, and confirm all KYC document requirements in advance.
• Incorrect entity choice. Choosing a branch when a subsidiary would be more tax‑efficient (or vice versa) can create long‑term structural problems. The decision should be made with input from both legal counsel and a Korean tax adviser before any filings are submitted.
• Missed tax and social insurance registrations. Failing to register for business tax within 20 days of commencing activities, or neglecting employer registration for the four social insurance programmes before the first payroll, can trigger fines and back‑dated contribution demands. Build these registrations into the project plan immediately after court registration.
