Registering your company in South Korea is only the first step in building a successful presence. Once incorporated, businesses must meet **ongoing compliance requirements** to stay legally active, avoid penalties, and maintain credibility with Korean authorities.

In this article, we outline the **key post-incorporation obligations** foreign companies should be prepared for in Korea.

### 1. Business Registration Certificate (사업자등록증) 📄

After incorporation, every company must obtain a **Business Registration Certificate** from the National Tax Service (NTS) within 20 days.

👉 Why it matters: This certificate is required for issuing tax invoices, hiring staff, and legally conducting business.

### 2. Tax Compliance and Filings 📊

Korean companies are subject to strict tax rules. Key obligations include:

- **Corporate income tax:** Progressive rates of 9–24%, plus local surtax (combined top ~26.4%).
- **VAT:** 10% standard rate on most goods and services.
- **Tax filing deadlines:**
  
    - VAT: filed quarterly.
    - Corporate income tax: filed annually, usually within three months of year-end.

👉 Tip: Maintain Korean GAAP-based accounting records to avoid audits.

### 3. Social Insurance Enrollment 👥

All companies employing staff must register them in Korea’s **four mandatory social insurances**:

- National Pension Service (NPS)
- National Health Insurance (NHIS)
- Employment Insurance
- Industrial Accident Compensation Insurance

👉 Tip: Non-compliance can lead to fines and back payments.

### 4. Annual General Meeting (AGM) & Reporting 🏢

- **Joint Stock Companies (JSC):** Required to hold annual shareholder meetings and file audited financial statements.
- **LLCs:** Less formal, but still must maintain proper internal records.

👉 Tip: Even if your entity is small, prepare meeting minutes and financial documentation to stay compliant.

### 5. Labor Law Compliance 📑

South Korea enforces strict labor protections, including:

- Maximum 52-hour work week.
- Severance pay (one month’s wages per year of service after one year).
- Detailed rules on termination and employee protections.

👉 Tip: Consider HR outsourcing or EOR support if you lack in-house expertise.

### 6. Industry-Specific Licenses 🔑

Depending on your sector, you may need to renew or maintain specific licenses (e.g. F&B, fintech, medical services).

👉 Tip: Always check if industry-specific regulations apply beyond the initial registration.

### 7. Ongoing Compliance Checklist ✅

- File taxes on time (corporate, VAT, local).
- Renew licenses as required.
- Maintain accounting records under Korean GAAP.
- Hold AGMs (if JSC).
- Keep HR, payroll, and social insurance in compliance.
