How to Register a Company in South Korea: A Step-By-Step Guide for Foreigners

Introduction

If you’re planning to expand into South Korea, one of the first decisions is how to establish a local presence. You can register a company in South Korea as a local corporation, open a branch office, or set up a liaison office. Each option serves a different purpose, so choosing the right structure early can affect how you operate later.

Setting up a company in South Korea also involves more than incorporation. Foreign investors must manage separate steps for investment notification, capital remittance, incorporation, business registration, banking, and foreign-invested company registration. Missing a document or completing a step out of order can cause unnecessary delays. 

In this guide, we – Source of Asia – break down the process step by step, including key requirements, costs, timelines, and practical considerations.

10 key steps for foreign businesses to register a company in South Korea

Phase 1: Before Registering A Company In South Korea

Good preparation can make the registration process smoother. Before companies register a company in South Korea, define the business structure, ownership, capital, registered address, and required documents.

Step 1: Choose the structure and company name

Start with how the business will operate in Korea, then choose the structure that supports it. For example:

1. Stock company: A common fit when the business expects multiple shareholders, external investment, or future expansion.
2. Limited company: Often works well for SMEs and closely held subsidiaries with simpler ownership.
3. Branch office: Lets a foreign company carry out commercial activities directly through its parent structure in Korea.
4. Liaison office: Useful for market research, promotion, and local coordination when the company does not plan to generate revenue in Korea.

After choosing the structure, check the proposed name through Korea’s Supreme Court Internet Registry. A conflict can stop the filing, force changes to prepared documents, and affect the registration timeline, so resolve name issues before submitting the application.

Step 2: Set ownership, capital, and office

Define the shareholders, ownership structure, representatives, and investment amount early in the setup. Under Korea’s Foreign Investment Promotion Act (FIPA), standard FDI recognition generally requires at least KRW 100 million and 10% or more of voting shares, subject to applicable rules. An alternative may apply where the foreign investor appoints or dispatches an executive to the Korean company.

Next, plan the capital around the company’s expected startup, staffing, and operating needs. Companies should also secure a registered business address that matches the planned activities. Since proof of address may be required for later registration and banking procedures, securing the location early can help prevent delays and keep the setup on track.

Step 3: Prepare the required documents

Once the structure, ownership, and business address are set, start gathering the documents needed to register a company in South Korea. The core package typically includes:

• Investor documents: Passport or corporate registration documents
• Company documents: Articles of Incorporation and shareholder information
• Authorization: Power of Attorney, where applicable
• Address proof: Office lease or registered address documents
• Investment proof: Documents showing the investment and capital remittance

For documents issued outside Korea, notarization, apostille, or consular confirmation, and Korean translation may be required, depending on the document and filing. Check these requirements early, as missing certification or an incorrect format can lead to rework and delay the registration process.

Step 4: File the foreign investment notification

Before sending investment funds into Korea, file the Foreign Investment Notification with KOTRA or a designated foreign exchange bank. This step records the proposed investment and gives the relevant authority the key details needed to process it. The notification covers key details such as the investor, investment amount, ownership structure, and planned business activities.

At this stage, document requirements vary by investor type. Individual investors typically provide a passport, while corporate investors may need incorporation or equivalent company documents. If an agent files on the company’s behalf, a Power of Attorney is required. Keep the notification record, as it will be needed for later registration steps.

Phase 2: During the Company Registration Process

Once the initial setup is complete, companies move to the capital remittance and incorporation stages required to register a company in South Korea. Each step must follow the required sequence and use the correct supporting documents to keep the process moving.

Step 5: Remit the investment capital

After filing the FDI notification, remit the investment capital through the designated foreign exchange bank. Companies should follow the bank’s transfer instructions carefully and use the correct investment purpose and recipient details.

After the funds arrive, keep the foreign currency purchase or remittance certificate issued by the bank. This document serves as proof of the capital transfer and may be required for incorporation. Checking the transfer details in advance can help avoid additional bank verification or delays.

Step 6: Register the incorporation

When the investment capital has been transferred, move to the formal incorporation filing. Companies should prepare the documents carefully because errors at this stage can require corrections before the registration is accepted.

1. Finalize the filing package: Prepare the incorporation documents, capital payment proof, corporate seal documents, and other required records.
2. Submit the application: File with the relevant court registry office and pay the required registration tax and fees.
3. Check the tax rate: The standard rate is 0.4% of paid-in capital. A 1.2% rate may apply in Seoul Metropolitan over-concentration areas, subject to exceptions.
4. Track the registration: Allow around 2–3 days once the application is complete and no corrections are required.
5. Budget the full cost: Include registration fees, local education tax, notarization, and company seal costs in the setup budget.

Step 7: Obtain required licenses and permits

Some business activities in South Korea require sector-specific licenses, permits, or approvals before operations can begin. These requirements should be identified early when planning to register a company in South Korea.

For example, according to the Ministry of Food and Drug Safety, medical device businesses may need product notification, certification, or approval depending on the device class. Similarly, food businesses must meet specific safety and reporting requirements.

For this reason, companies should check these requirements during the setup stage and complete them in the required order. Licensing may take longer than incorporation, so early planning helps avoid launch delays.

Step 8: Complete business registration

After incorporation, register the company with the National Tax Service (NTS) and obtain the Business Registration Certificate. This registration supports tax administration and is commonly required for practical steps such as invoicing and opening the corporate bank account.

Companies generally need to complete business registration within 20 days of starting business activities. Processing usually takes around 3 days when the application and supporting documents are complete. Typical documents include:

• Business registration application
• Incorporation registration certificate
• Articles of Incorporation
• Lease contract and shareholder information
• Relevant licenses or permits, where applicable

Phase 3: After Opening A Company In South Korea

With the legal entity in place, companies still need to complete several post-registration steps before starting full operations. The focus now shifts to corporate banking and foreign-invested company registration.

Step 9: Open the corporate bank account

A corporate bank account is needed for payroll, supplier payments, tax, and other daily transactions. Companies can apply through a foreign exchange bank and should prepare the main corporate records, including:

• Incorporation registration certificate
• Business Registration Certificate
• Corporate seal documents
• Representative’s passport and shareholder information

Bank requirements can vary, so check the document list with the selected bank in advance. It is also worth choosing the bank carefully, as opening another corporate account with a different bank is generally restricted for 20 business days after the first account is opened.

Step 10: Complete foreign-invested company registration

At the final stage, register the company with KOTRA or the foreign exchange bank where the original FDI notification was filed. Under the Foreign Investment Promotion Act, this registration should generally be completed within 60 days after the investment capital has been paid.

Prepare the key documents, including:

• Incorporation registration certificate
• Foreign currency purchase certificate
• Shareholder list
• Business Registration Certificate
• Application form and Power of Attorney, where applicable

The registration certificate can support later foreign-exchange, investment, and other administrative procedures, making it an important final step in the FDI setup process.
