   Understanding the differences between a subsidiary and a branch office is crucial. For instance, a subsidiary allows for greater operational autonomy, which may appeal to companies looking to develop distinct market strategies in Korea.

   Ensuring you have the right payroll structure in place is vital when you set up a company in Korea.

1. Subsidiary vs. Branch in Korea

Choosing the right structure helps when you set up a company in Korea and navigate the local market.

For example, a foreign company in the tech industry might prefer a subsidiary to tailor its products for the Korean market, while a consulting firm may opt for a branch to leverage existing networks and resources quickly.

There are two main structures for foreign companies:

• Subsidiary (foreign-invested corporation) – A separate legal entity under Korean law. It requires paid-in capital and provides more independence.

• Branch office – An extension of the parent company, simpler to register but less flexible in tax and liability planning.

👉 Choosing between a Korean subsidiary and branch depends on your business strategy, tax goals, and long-term plans.

2. Hiring Foreign Employees in Korea

To employ foreign nationals, companies must secure proper work visas such as the D-8 Investor Visa or E-7 Specialist Visa.

⚠️ At Star Tax & Legal, we do not directly process visas, but we can introduce trusted immigration law firms who specialize in visa sponsorship and work permits. For official information, you can also refer to Invest Korea – Business Setup Guide

3. Payroll & Social Security Contributions

All employers must register employees in the Four Major Insurances:

• National Pension – 4.5% each (employer and employee).

• National Health Insurance – Around 3.5% each, plus long-term care contribution.

• Employment Insurance – Employer and employee share, depending on company size.

• Industrial Accident Compensation Insurance – Fully paid by the employer.

👉 For more details on contribution rates, see the National Pension Service (NPS) website.

4. Labor Law Requirements

Korean labor law requires:

• Written employment contracts

• Compliance with minimum wage (KRW 10,030/hour in 2025)

• Standard working hours: 40 hours/week, with regulated overtime

• Severance pay after 1 year of service

• Monthly income tax withholding and filing

👉 Employers should review the Korean Labor Standards Act for up-to-date regulations.

5. Tax & Ongoing Compliance

Tax planning becomes necessary to ensure profitability as you set up a company in Korea.

Understanding the implications of the taxation system in Korea can lead to better financial outcomes. Engaging with a local tax advisor can help you navigate the complexities of tax laws and identify applicable deductions.

Once established, foreign companies in Korea must:

• File VAT returns quarterly

• File corporate income tax (CIT) annually

• Maintain proper bookkeeping and annual financial statements

• Hold an annual shareholders’ meeting

• Report shareholder and director changes to the authorities

Budgeting correctly can alleviate unexpected costs when you set up a company in Korea.

Costs for registration can also vary significantly based on the industry. For example, technology companies may face different regulatory hurdles compared to retail businesses, influencing their overall registration costs.

Our service fees for company establishment start from USD 3,000.

The final cost depends on:

• Subsidiary vs. branch setup

• The amount of paid-in capital invested

• Complexity of shareholder structure and required documents

⚠️ Small-capital entities often face stricter government reviews, making the process more time-consuming and challenging.
