Registering a company in South Korea involves five distinct government steps — each with its own documents, fees, and timelines. This guide breaks down every stage so foreign executives know exactly what to expect before they start.

🎙 This article is available in audio format. [Listen Now]

South Korea ranks among Asia's most attractive FDI destinations — [Insert current FDI inflow stat from KOTRA/MoE 2025–2026]. But when foreign executives start the company registration process, most are surprised to find it works nothing like their home market.

Korea's incorporation process runs across five distinct government agencies, in a mandatory sequence. Skip a step or submit documents in the wrong format, and you restart from the point of failure — losing weeks.

This guide covers every stage of company registration in South Korea for foreign investors: what documents you need, how long each step takes, what it costs, and where the common mistakes happen.

Why Korea's Registration Process Works Differently

Unlike Singapore's single-window ACRA system (completable in hours) or the UK's Companies House portal (same day), Korea's system uses a sequential approval logic. Each step depends on the previous one being completed correctly.

The five-step sequence is non-negotiable:

1. MOFA Notarization — Authenticate your overseas company documents
2. Invest Korea FDI Notification — Declare your foreign direct investment via KOTRA
3. Court Registry Incorporation — Legally establish your Korean entity
4. NTS Tax Registration — Obtain your 사업자등록증 (Business Registration Certificate)
5. Business License Application — Sector-specific licensing where required

Total typical timeline: 4 to 8 weeks. With a local specialist: 3 to 5 weeks.

Step 1: MOFA Notarization — Authenticating Your Home Country Documents

Before filing anything in Korea, your parent company's founding documents must be legally authenticated for use in Korea.

Documents required:

• Certificate of Incorporation of the parent company
• Articles of Association / Memorandum of Association
• Board resolution authorizing the Korea incorporation
• Passport copies of directors and authorized signatories
• Power of attorney for your Korea-based representative (if applicable)

Apostille vs. consular legalization: Most Western countries, Australia, and Singapore are Hague Convention signatories — apostille is sufficient. Some Southeast Asian countries require the additional step of Korean consular legalization through the Korean embassy in your home country.

Estimated time: 1–3 weeks

Estimated cost: USD 200–800 depending on jurisdiction

Common mistake: Documents apostilled for a different country, expired corporate certificates, or apostille stamps that don't meet Korean consulate specifications. Verify requirements directly with the Korean consulate before submitting.

Step 2: FDI Notification via Invest Korea (KOTRA)

With authenticated documents in hand, file a Foreign Direct Investment (FDI) notification through Invest Korea, KOTRA's investment arm.

Under Korea's Foreign Investment Promotion Act (FIPA), any foreign entity establishing a Korean company and transferring capital must register that investment before — or immediately after — the capital transfer.

Minimum investment for FDI status: KRW 100 million (approximately USD 75,000), which qualifies your entity as a "foreign-invested company" under FIPA — unlocking certain tax incentives and regulatory preferences.

The Invest Korea FDI notification can in many cases be filed directly at the Korean bank, streamlining this step.

Estimated time: 1–5 business days for notification; 1–2 additional weeks for Korean bank account setup

Estimated cost: No government filing fee

Note on bank account opening: Korean banks typically require an in-person meeting with the legal representative or an authorized attorney. Start the bank process early.

Step 3: Court Registry Incorporation — Legally Creating Your Korean Entity

With FDI notification confirmed and capital deposited, proceed to the district court registry (지방법원 등기소). This is the step that legally creates your Korean company.

Entity type determines your document requirements:

• 주식회사 (Jushik Hoesa / Stock Company) — Most common for foreign subsidiaries. Statutory auditor required if capital exceeds KRW 1 billion.
• 유한회사 (Yuhan Hoesa / LLC) — Simpler structure, lower compliance burden, preferred for smaller operations or holding structures.

Documents required:

• Korean-language Articles of Incorporation (정관) — must meet Korean Commercial Code standards
• Board resolution (in Korean)
• Capital deposit certificate from your Korean bank
• Invest Korea FDI notification confirmation
• Corporate seal (법인인감) — registered at this stage
• Identity documents for all directors

Key output: The 법인등기부등본 (Corporate Registration Certificate) — your proof of legal existence in Korea, required for every subsequent step.

Estimated time: 3–7 business days after complete submission

Estimated cost: ~0.4% of registered capital (minimum KRW 112,500), plus notarization and attorney fees

Common issue: Articles of incorporation drafted by overseas lawyers without Korean law expertise are regularly rejected. Always use a Korean-qualified specialist for this document.

Step 4: NTS Tax Registration — Your 사업자등록증

Within 20 days of commencing business operations, register with the National Tax Service (국세청, NTS) at the local tax office nearest your business address.

This produces your 사업자등록증 (Business Registration Certificate) — the single most referenced document in Korean business. Every supplier, client, bank, and government authority will request it.

NTS tax registration in Korea also automatically enrolls your company in the VAT (부가가치세) system. Most businesses file VAT returns twice per year.

Documents required:

• 법인등기부등본 (Corporate Registration Certificate from Step 3)
• Office lease agreement (or virtual office agreement where permitted)
• Alien registration card or passport of the legal representative
• Business activity description and industry classification code (업종코드)

Estimated time: 3–5 business days

Estimated cost: No government fee

Office address note: You must have a verifiable Korean business address. Virtual offices are accepted in most business categories, but regulated industries may require a physical office. [Link: pearsonkorea.com/korea-virtual-office]

Step 5: Business License Application

For most general business activities, your 사업자등록증 effectively serves as your operating license. However, regulated industries require additional ministry licenses before commencing operations.

If your business falls into a regulated category, identify the licensing requirement at Step 1 — before spending money on notarization.
