How to register a company in South Korea: A step-by-step guide.

South Korea is recognised for its economic stability, advanced technological infrastructure and advantageous location in Northeast Asia. As a member of the OECD and a global leader in innovation, South Korea offers compelling opportunities for international businesses and investors. However, establishing a legal entity requires careful planning and full compliance with local regulations.

This guide provides a detailed overview of the company registration process in South Korea, covering all essential steps, pre-registration, registration and post-registration, to facilitate an informed and structured market entry.

Pre-registration

The pre-registration phase focuses on establishing the legal and operational framework of the company. Proper structuring and documentation at this stage are critical for a streamlined registration process and long-term compliance.

Select an appropriate business structure

Several types of business structures are available in South Korea, including:

• A private limited company (Yuhan Hoesa) is suited for small to medium-sized enterprises with limited shareholder liability.
• A stock company (Chusik Hoesa) is common among larger companies or those seeking to raise external capital, and it is subject to more stringent governance requirements.
• A branch is an extension of a foreign company, which is capable of conducting commercial activities but not a separate legal entity.
• A liaison office is restricted to non-commercial functions such as research, promotion or coordination, and not permitted to engage in revenue-generating activities.

Each legal structure entails specific tax, governance and regulatory implications that must be considered prior to incorporation.

Reserve a company name

A company name must be unique and compliant with Korean legal naming conventions. The name should not duplicate or closely resemble existing business names or trademarks.

Verification can be conducted through the Supreme Court’s online registry system. Certain terms may require special approval or are restricted entirely.

Determine share structure and capitalisation

It is essential to define the total issued capital, nominal share value and ownership allocation among shareholders. Although there is no statutory minimum capital requirement, a minimum paid-up capital of KRW 100 million is commonly recommended, particularly when applying for business investment visas or seeking bank financing.

Appoint shareholders

At least one shareholder is required and may be either an individual or a legal entity, regardless of nationality. Documentation such as identification (passport or corporate registration certificate) and signed consent forms must be prepared. Investments exceeding KRW 100 million may qualify for foreign investment incentives, including visa eligibility.

Appoint directors

A minimum of one director must be appointed. Directors are not required to reside in South Korea, although a local director can facilitate certain administrative tasks, such as opening a bank account or interacting with local authorities. For stock companies, at least three directors and one statutory auditor are required unless exempted under specific criteria.

Designate a company secretary (optional)

Although not legally required under South Korean corporate law, appointing a company secretary or engaging a corporate service provider is considered best practice for managing regulatory compliance, corporate governance and ongoing filings.

Secure a registered business address

All companies must maintain a separate address by physical location or virtual address (i.e., P.O box) in South Korea, which will serve as the legal domicile for official communications and government inspections. A lease agreement must be submitted during registration. In some jurisdictions, virtual office services may be acceptable if compliant with local zoning laws.

Prepare constitutional documents

The Articles of Incorporation must be drafted in Korean and notarised, outlining key details such as business objectives, governance structure, share distribution and internal controls. In cases involving foreign shareholders, a certified translation may also be required.

Company registration with the Registry Office

After completing the preparatory work, the company must be formally incorporated through the appropriate government channels to achieve legal status.

Step 1. File for incorporation with the commercial registry

The registration application must be submitted to the District Court’s Commercial Registry Office.

Required documents typically include:

• Articles of Incorporation
• Identification documents and consent letters from shareholders and directors
• Lease agreement for the registered address
• Bank certificate confirming capital deposit
• Company Seal Certificate
• Incorporation application forms

Capital must be deposited into a temporary account prior to incorporation, and ownership is transferred to the company post-registration.

The incorporation process generally takes three to five business days, depending on the completeness of documentation and court processing time.

Step 2. Obtain a business registration certificate

Upon successful incorporation, the business must register with the National Tax Service (NTS). A Business Registration Certificate must be obtained to legally engage in commercial activities, issue tax invoices and open a corporate bank account.

The application must include court-issued registration documents, lease details and identification of key officers.

Post-registration

Several post-registration procedures are necessary to finalise the company’s setup and ensure legal compliance with ongoing operational obligations.

Receive certificates and official documents

The following documents will be issued after incorporation:

• Certificate of Incorporation
• Business Registration Certificate
• Company Seal Certificate

These documents are essential for banking, immigration applications, licensing and future compliance activities.

Select preferred document format

Companies may choose to receive incorporation and registration documents in electronic or physical format. Electronic versions offer increased convenience and are commonly accepted for most formal applications.

Open a corporate bank account

A corporate bank account must be opened in the company’s name.

Requirements generally include:

• Business and incorporation certificates
• Company seal and seal certificate
• Representative’s identification documents
• Office lease agreement
• Board resolution (if applicable)

Some financial institutions may request in-person verification or business plans, especially for foreign-invested companies.

Apply for sector-specific licences or permits

Depending on the nature of operations, additional permits may be required. Industries such as finance, education, healthcare, F&B and logistics are subject to specific regulatory approvals. Licences must be obtained from the competent authorities before engaging in regulated activities.

Secure visas and work permits

Foreign executives and staff may require a D-8 (Business Investment) visa or other applicable work permits. Visa eligibility typically requires proof of investment (minimum KRW 100 million), office lease and valid business registration. Applications must be submitted through the Korea Immigration Service or Korean consulates abroad.

Establish accounting and compliance systems

Entities operating in South Korea must comply with accounting standards prescribed under K-GAAP or K-IFRS, depending on size and business type. Accounting systems should be implemented to support accurate recordkeeping, tax reporting and statutory compliance. It is common practice to engage licensed tax agents or accounting professionals for these purposes.

Fulfil tax registration and filing obligations

Registered companies are subject to the following taxes:

• Corporate income tax: Ranges from 9% to 24%, based on income thresholds
• Corporate local income tax: 10% of corporate income tax
• Value-added tax (VAT): Standard rate of 10% on most goods and services
• Withholding tax: Applicable to payments such as salary, dividend, interest and royalty to residents or non-residents

Timely and accurate tax filings are essential to avoid penalties and maintain a good standing with the NTS.

Meet annual reporting and compliance requirements

All companies must:

• File annual tax returns with the NTS
• Submit audited financial statements (where applicable)
• Hold Annual General Meetings (AGMs)
• Report changes in shareholding or management
• Submit reports to the Ministry of Trade, Industry and Energy (for foreign-invested entities)

Audit requirements apply to companies exceeding certain thresholds related to capital, assets or number of employees.

Conclusion

Understanding how to register a business in South Korea is essential for establishing a legally compliant and operational entity in one of Asia’s most advanced economies. The steps to starting a company in South Korea involve a structured approach, beginning with entity selection and legal documentation, followed by incorporation, licensing and post-registration compliance.

While the process can be managed independently, many foreign investors opt to engage legal, tax and corporate service professionals to navigate the regulatory landscape efficiently and mitigate potential risks. A well-executed incorporation strategy supports long-term operational success and ensures alignment with South Korea’s legal and administrative frameworks.
