How to Start a Business in Korea: 10 Essential Steps for Foreigners
For foreigners who want to do business in Korea, one of the first questions is usually:
“Can a foreigner legally start and operate a company in Korea?”
The answer is yes.
Foreigners can establish a Korean corporation, operate a sole proprietorship, open a branch office, or set up a liaison office depending on their purpose.
However, actually starting a business requires more than simply registering a company.
You need to plan the legal structure, foreign investment, capital transfer, corporate registration, tax registration, banking, office space, accounting, hiring, social insurance, and visa status.
For a company to qualify as a foreign-invested company under Korea’s Foreign Investment Promotion Act, a common standard is an investment of at least:
KRW 100 million
approximately US$73,600
together with ownership of at least 10% of the voting shares or equity interest.
A foreigner may still establish a company with less capital, but it may not qualify as foreign direct investment under the foreign investment framework.
The 10-Step Roadmap
| Step | Key Action | Main Institution | Typical Timing |
|---|---|---|---|
| 1 | Choose a business structure | Founder / adviser | 1–3 days |
| 2 | File a foreign investment notification | KOTRA / designated bank | Same day–1 day |
| 3 | Transfer investment capital | Foreign exchange bank | About 2–3 days |
| 4 | Incorporate and register the company | Court registry office | Several days |
| 5 | Register the business | Tax office | About 3 days |
| 6 | Register as a foreign-invested company | KOTRA / bank | Several days |
| 7 | Open a corporate bank account | Korean bank | 1 day or longer |
| 8 | Set up accounting and tax systems | Tax office / tax accountant | Ongoing |
| 9 | Hire employees and enroll in social insurance | Relevant public agencies | After hiring |
| 10 | Secure the proper visa and use support programs | Immigration / KOTRA, etc. | Case by case |
In practice, the core sequence is:
Foreign Investment Notification → Capital Transfer → Corporate Registration → Business Registration → Foreign-Invested Company Registration
STEP 1. Choose the Right Business Structure
The first decision is one of the most important.
Foreigners generally consider one of the following options.
| Structure | Main Feature | Best For |
|---|---|---|
| Korean corporation | Separate Korean legal entity | Long-term business in Korea |
| Korean branch of foreign company | Extension of overseas headquarters | Existing overseas companies |
| Liaison office | Cannot generate business revenue | Market research and representative activities |
| Sole proprietorship | Business operated by an individual | Small-scale business or self-employment |
Most Common Choice
If you plan to:
- Generate revenue
- Hire employees
- Sign commercial contracts
- Raise investment
- Build a long-term presence in Korea
a Korean corporation is often the most practical structure to consider.
A Korean corporation is legally separate from the overseas parent company.
A branch office, on the other hand, remains part of the foreign headquarters.
A liaison office may conduct activities such as market research and communication, but it generally cannot engage in profit-generating sales activities.
STEP 2. File a Foreign Investment Notification
If you intend to establish a foreign-invested company, the usual process begins with a foreign investment notification before transferring the investment funds.
This can generally be handled through:
- KOTRA
- A designated foreign exchange bank
Common Investment Threshold
A standard benchmark for foreign direct investment is:
KRW 100,000,000 or more
approximately US$73,600 or more
and, in general,
10% or more of the voting shares or equity interest.
Important
KRW 100 million is not necessarily the same thing as a statutory minimum capital requirement for forming a company.
A corporation may be created with less capital, but it may not be recognized as a foreign-invested company for FDI purposes.
STEP 3. Transfer the Investment Capital to Korea
After filing the foreign investment notification, the next step is to transfer the investment funds into Korea.
For example:
Investment Amount
KRW 100,000,000
approximately
US$73,600
The transfer should be clearly identifiable as investment capital rather than as a personal remittance or living-expense transfer.
Keep all supporting documents, including:
- Overseas remittance receipt
- Foreign exchange purchase certificate
- Foreign investment notification
- Investor passport
- Proof of source of funds
These documents can later be important for:
- Corporate registration
- Foreign-invested company registration
- D-8 visa applications
- Banking
- Compliance reviews
STEP 4. Incorporate and Register the Company
This is the stage where the company legally comes into existence.
For a typical stock corporation, you will need to decide:
- Company name
- Registered office address
- Business purposes
- Capital amount
- Shareholders
- Ownership ratios
- Representative director
- Directors
- Fiscal year
Corporate Registration Costs in Seoul
Corporate establishment involves registration taxes and related fees.
As a general rule, registration license tax may be calculated at approximately 0.4% of paid-in capital.
In certain Seoul metropolitan overconcentration control areas, a higher rate can apply, often effectively around 1.2%, depending on the location and business.
A local education tax is also typically imposed.
Example: Company with KRW 100 Million in Capital
| Item | Example Amount | Approx. USD |
|---|---|---|
| Registration license tax | KRW 1,200,000 | US$883 |
| Local education tax | KRW 240,000 | US$177 |
| Registry-related fees | Additional | Additional |
| Professional service fees | Additional | Additional |
In practice, the total corporate setup cost can be higher once notarization, registry fees, legal support, and administrative services are included.
STEP 5. Secure an Office and Register the Business
To operate legally, the company needs a registered business address.
Common options include:
- Traditional office
- Shared office
- Business center
- Manufacturing facility
- Retail or commercial space
Practical Office Budget Example in Seoul
| Office Type | Monthly Cost Example | Approx. USD |
|---|---|---|
| Small shared office | KRW 300,000–700,000 | US$220–515 |
| Small private office | KRW 700,000–1,500,000 | US$515–1,104 |
| Small traditional office | KRW 1,000,000–3,000,000+ | US$736–2,208+ |
These are practical market estimates, not fixed legal fees.
Actual costs vary depending on:
- District
- Size
- Deposit
- Building grade
- Included services
Documents Commonly Needed for Business Registration
- Business registration application
- Corporate registry certificate
- Articles of incorporation
- Shareholder list
- Office lease agreement
- Representative’s passport
- Foreign investment documents
- Industry-specific licenses, if required
STEP 6. Register as a Foreign-Invested Company
This is often confused with the initial foreign investment notification.
They are different.
At the beginning, you file a notification saying:
“I intend to invest in Korea.”
After the capital has been transferred and the company has been established, you then register the completed investment.
This registration is generally handled through:
- KOTRA
- The foreign exchange bank that processed the investment
The registration should generally be completed within the required period after the investment has been fully made.
The foreign-invested company registration certificate can be important for:
- Visa applications
- Investment-related procedures
- Administrative documentation
- Government support programs
STEP 7. Open a Corporate Bank Account
Once the company has been registered and has received its business registration certificate, you can open a corporate bank account.
Banks may request documents such as:
- Corporate registry certificate
- Business registration certificate
- Corporate seal certificate
- Corporate seal
- Representative’s passport
- Shareholder list
- Beneficial owner information
Be Prepared for Compliance Checks
Korean banks may review the substance and purpose of the business due to anti-money-laundering and fraud-prevention requirements.
It can help to prepare:
- Company website
- Office lease agreement
- Business contracts
- Business plan
- Customer or supplier documents
- Investment remittance records
STEP 8. Understand Korean Taxes
Once the company begins operating, tax management becomes essential.
1. Value-Added Tax
The standard VAT rate in Korea is generally:
10%
For example:
Net price:
KRW 1,000,000
VAT:
KRW 100,000
Total:
KRW 1,100,000
2. Corporate Income Tax
Corporate income tax is calculated according to taxable income brackets.
A simplified structure is:
| Taxable Income | Corporate Tax Rate |
|---|---|
| Up to KRW 200 million | 10% |
| KRW 200 million–20 billion | 20% |
| KRW 20 billion–300 billion | 22% |
| Over KRW 300 billion | 25% |
For example, if taxable income is:
KRW 100 million
approximately US$73,600
the company would generally fall within the 10% bracket before considering deductions, credits, exemptions, and local tax.
Actual tax liability can vary significantly depending on:
- Deductible expenses
- Tax credits
- Investment incentives
- Industry
- Location
- Loss carryforwards
STEP 9. Hire Employees and Enroll in Social Insurance
Once you hire employees in Korea, payroll is not your only labor cost.
The four major social insurance systems are:
- National Pension
- National Health Insurance
- Employment Insurance
- Industrial Accident Compensation Insurance
Typical Employer Burden
| Insurance | Employee Share | Employer Share |
|---|---|---|
| National Pension | 4.75% | 4.75% |
| Health + Long-Term Care | About 4.07% | About 4.07% |
| Employment Insurance | 0.9% | 0.9% + additional contribution |
| Industrial Accident Insurance | None | Employer pays, rate varies by industry |
Example
If an employee earns:
KRW 4,000,000 per month
approximately
US$2,944 per month
the employer’s real cost will be higher than KRW 4 million because the company also needs to consider:
- Employer social insurance
- Severance obligations
- Benefits
- Recruiting costs
- Administrative costs
A practical labor budget should therefore be higher than the employee’s stated salary.
STEP 10. Secure the Proper Visa and Use Business Support Programs
Forming a company does not automatically give a foreign founder the right to live in Korea long term.
One of the main visa categories for foreign investors is:
D-8 Business Investment Visa
A foreign investor may qualify for a D-8-1 visa when, among other requirements, the investor:
- Invests at least KRW 100 million from overseas
- Holds at least 10% of the company’s equity
Common Documents
- Passport
- Foreign-invested company registration certificate
- Business registration certificate
- Corporate registry documents
- Shareholder information
- Capital remittance evidence
- Use-of-funds records
- Office lease agreement
- Proof of actual business activity
Important
Creating a company does not guarantee a visa.
Immigration authorities may review:
- Whether the business is actually operating
- Whether the office is genuine
- Whether the investment capital was actually used for business
- Whether the company has real commercial substance
What About Sole Proprietorships?
A foreigner may also consider operating as a sole proprietor.
However, if the goal is to secure long-term business-related residency, the visa framework can be different.
For certain D-9 individual business investment structures, a much higher investment amount may apply.
For example:
KRW 300 million
approximately
US$220,800
can be a relevant threshold in certain cases.
This is why a foreign founder should compare:
Corporation + D-8
versus
Sole Proprietorship + D-9
before choosing the structure.
How Much Money Do You Really Need?
This is one of the most important questions for foreign entrepreneurs.
Example: Small Service Company in Seoul
| Item | Practical Budget Example | Approx. USD |
|---|---|---|
| Investment capital | KRW 100,000,000 | US$73,600 |
| Incorporation taxes and fees | KRW 2,000,000–4,000,000 | US$1,472–2,944 |
| Legal / professional support | KRW 1,000,000–3,000,000 | US$736–2,208 |
| Office deposit | KRW 3,000,000–20,000,000 | US$2,208–14,722 |
| Monthly office cost | KRW 500,000–2,000,000 | US$368–1,472 |
| Accounting / tax support | KRW 150,000–500,000 per month | US$110–368 |
| Initial website / marketing | KRW 2,000,000–10,000,000 | US$1,472–7,361 |
| Other setup expenses | KRW 2,000,000–5,000,000 | US$1,472–3,680 |
Important
The KRW 100 million investment capital is not simply a fee that disappears.
It becomes capital of the company and may be used for legitimate business operations.
