South Korea – Self-Employment

How does self-employment work for expats in South Korea?

South Korea manages all foreign work and commercial activity through a visa-based framework. Foreign nationals are required to hold an appropriate visa before beginning any employment or business operation, and the country maintains numerous visa categories covering a wide range of work types and arrangements. Most importantly, the visa category you hold dictates what forms of self-employment or business activity you are legally entitled to pursue — operating outside those permitted boundaries can carry serious immigration consequences.

Expats wishing to work independently or establish a business in Korea will find the most relevant options among the D-8 (Corporate Investor/Investment Visa) and selected long-stay F-series visas. The D-8 serves as the principal route for foreign investors and company founders and typically requires a minimum investment of KRW 100 million to incorporate a foreign-invested company. Holders of F-visas — including the F-4 (Overseas Korean) and F-5 (Permanent Resident) — are generally able to establish a basic sole proprietorship with relative ease.

Self-employment in South Korea falls broadly into two categories: sole proprietorship (개인사업자, gaeinsaeopja) or a corporate entity. Unlike the relatively simple process in the UK, where a sole trader merely notifies HMRC via self-assessment, establishing a sole proprietorship in Korea requires obtaining a Business Registration Certificate (사업자등록증) from the National Tax Service. While the country is genuinely welcoming to foreign direct investment, this registration involves a defined series of legal steps.

The range of visa types and work authorisation categories in South Korea can feel daunting to new arrivals. Anyone weighing up self-employment options should verify their visa permissions directly with the Korea Immigration Service (HiKorea) before taking any further steps.

What are the different self-employment and business structures available in South Korea?

South Korea offers several distinct company structures, each suited to different scales of operation and ownership arrangements. The Joint Stock Company (Chusik Hoesa) is the most widely recognised option for foreign investors, permitting the public issuance of shares with shareholder liability confined to invested capital. It requires at least one general shareholders’ meeting each year.

The Limited Liability Company (Yuhan Hoesa) is a popular choice, especially among closely held businesses with up to 50 shareholders. It is straightforward in its requirements: at least one director, one shareholder of any nationality, no minimum capital threshold, and a registered office address. This structure is broadly comparable to a private limited company in Ireland or a GmbH in Germany, making it well-suited to small and medium-sized foreign-owned ventures where owners want liability protection without the administrative weight of a full joint-stock company.

Further options include the General Partnership (Hapmyung Hoesa), where all partners bear unlimited liability and are jointly accountable for business obligations, with ownership changes requiring unanimous agreement. There is also the Limited Liability Partnership (Hapja Hoesa), which permits partners to choose between roles carrying limited or unlimited liability. These partnership forms are less popular among expats, largely because of the exposure to unlimited liability.

Foreign companies seeking a foothold in Korea without full local incorporation may consider a branch office or a liaison (representative) office. A branch office is treated as an extension of the overseas parent company, meaning it can only engage in activities consistent with those of the parent, and the parent bears full responsibility for all liabilities the branch incurs. Many foreign enterprises choose to begin with a representative office, given its comparatively straightforward registration requirements.

For most expats planning to build a substantive local business, the Yuhan Hoesa (LLC) is generally the most advisable starting structure. It combines meaningful liability protection with administrative simplicity and flexible ownership arrangements for foreign nationals.

How do you register as self-employed in South Korea?

Registering as a sole proprietor in South Korea is considerably simpler than incorporating a company, but it still involves a series of defined steps across multiple government bodies. Below is a step-by-step overview of what the process entails:

1. Confirm your visa status. Before filing any registration, verify that your current visa permits self-employment or business activity. F-4, F-5, and F-6 visa holders generally have broad work permissions. If you hold a D-series or E-series visa, check the precise conditions applicable to your category with the Korea Immigration Service at HiKorea.
2. Obtain your Alien Registration Card (ARC). Foreign nationals need a valid visa or Alien Registration Card (ARC) to proceed with business registration. If you have been in Korea for more than 90 days, you should already hold an ARC issued by your local immigration office.
3. Choose your business activity code. The NTS classifies all business types using a specific industry code system (업종코드). You will need to identify the correct code for your activity before submitting your registration. A local tax accountant (세무사, semusa) can help with accurate classification.
4. Register with the National Tax Service (NTS). Business registration is filed with the National Tax Service, usually at the local Tax Office (Se-mu-seo) that has jurisdiction over your business address. You may apply within 20 days from your business start date, or you can begin the process before operations commence. Personal attendance is required when applying yourself.
5. Submit required documents. You will typically need to provide your passport and ARC, proof of your business address (such as a lease agreement or address confirmation), and details of your intended business activity. Where an agent submits on your behalf, both the applicant’s and agent’s identification documents are required, and all personal details must be included in the submission.
6. Receive your Business Registration Certificate. Upon approval, you will be issued the Business Registration Certificate (사업자등록증). This document underpins your sole trader status and is essential for issuing invoices, opening a business bank account, and completing tax filings.
7. Register for VAT if applicable. A standard VAT rate of 10% applies to most goods and services, and all businesses in South Korea must register for VAT with the National Tax Service within 20 days before commencing business. Very small operators may be eligible for simplified VAT status; check current thresholds directly with the NTS.
8. Enrol in social insurance if hiring staff. If you take on employees — including yourself in a director capacity — you must register them for mandatory National Pension, National Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance coverage.

The NTS sole proprietorship registration process is generally rapid, often finalised within a few days once all documentation is in order. There is no government registration fee for registering a sole proprietorship with the NTS, though you should factor in the cost of engaging a local accountant for assistance. Fees and timelines are subject to change; always verify current requirements directly with the National Tax Service.

How do you set up a company in South Korea as an expat?

Foreign-owned entities in South Korea can enjoy full ownership rights, allowing non-Korean nationals to incorporate structures such as a local LLC with minimal requirements: at least one director, one shareholder of any nationality, and a legally registered office address. This is a notably permissive framework compared to many other markets, where local director mandates or ownership caps are routine. The following is a step-by-step guide to the incorporation process for a foreign-invested company:

1. Decide on your business structure. Select between a Yuhan Hoesa (LLC), Chusik Hoesa (Joint Stock Company), branch office, or liaison office. For the majority of expat founders, the LLC is recommended on the basis of its relative simplicity and built-in liability protection.
2. Notify a Foreign Exchange Bank (FEB). Foreign-invested companies must report the investment to a designated Foreign Exchange Bank, which will then issue a Foreign Investment Notification Certificate. This notification may alternatively be submitted through KOTRA’s (Korea Trade-Investment Promotion Agency) overseas offices.
3. Remit your investment capital. The required minimum capital is transferred to a temporary capital custody account at the FEB, which in turn issues a Capital Deposit Certificate. Under the Foreign Investment Promotion Law (FIPL), the minimum investment required for FDI classification is KRW 100 million (approximately USD $90,000) as of 2024. Note that a private Yuhan Hoesa without FDI status has no statutory minimum paid-up capital requirement, but the FDI minimum applies when seeking an investor visa or FDI classification.
4. Draft and notarise Articles of Incorporation (AOI). The Articles of Incorporation is a comprehensive document setting out the company’s purpose, structure, management arrangements, and shareholding. It must be executed before a notary.
5. File with the Court Registry. Director and shareholder documentation, proof of capital, and other required materials are submitted to the Court Registry, which then issues the Certificate of Corporate Registration (Beop-in Deung-gi Bu Deung-bon), formally establishing the company in law.
6. Secure a registered office address. Every company must have a registered office address in South Korea, supported by a lease agreement confirming the physical location. Depending on the nature of your business, this may be a dedicated office, a co-working space, or a virtual office arrangement.
7. Register with the National Tax Service (NTS). All companies must register with the NTS to obtain a Tax Identification Number and to register for corporate income tax and VAT obligations.
8. Open a corporate bank account. A corporate bank account must be established before operations begin in earnest, as it is fundamental to business transactions, asset management, accounting, and tax filing. Well-regarded options include Woori Bank, Korea Development Bank, and KEB Hana Bank.
9. Apply for the appropriate visa. Foreign entrepreneurs must apply for the D-8 entrepreneur visa by submitting the prescribed application form together with evidence of the investment and completed company registration.

Most companies can be incorporated within 2–4 weeks (as of 2025), depending on the chosen entity type, how readily documentation can be assembled, and the time required for licensing and banking steps. The most significant variable is typically the time needed for notarisation, apostille, or consular legalisation of foreign-issued documents — initiating that process early can substantially reduce the overall timeline.

Physical presence is not always required, as many steps can be handled under a Power of Attorney, depending on circumstances and structure. Always verify current minimum capital requirements, fee schedules, and procedures with Invest Korea or the relevant court registry.

Can you work as a digital nomad in South Korea?

From 1 January 2024, South Korea’s Digital Nomad Visa — officially designated the F-1-D, and widely referred to as the “Workation” visa — became available for applications, positioning South Korea among the growing number of countries offering a dedicated pathway for remote workers. Before this, digital nomads working in Korea while visiting under tourist visas of up to 90 days were typically doing so in a legal grey area.

The Workation Visa permits holders to live and work in South Korea for an initial period of one year, with the option to extend for a further year, giving a maximum stay of two years. Applicants may bring their spouse and dependent children, making the F-1-D a practical choice for families as well as solo nomads.

To be eligible for the F-1-D visa, applicants must satisfy the following key conditions:

• Income threshold: Applicants must demonstrate annual earnings exceeding ₩88,102,000 (approximately $66,000), a figure that represents more than double South Korea’s Gross National Income per capita as of July 2024. This threshold is recalculated each year, so prospective applicants should verify the current figure before submitting an application.
• Work type: You must be either a remote employee of a foreign-based company or a self-employed professional whose income derives from outside South Korea. Visa holders may work remotely for overseas employers, but engaging in paid work or profit-generating activities within South Korea is not permitted.
• Work experience: Applicants must be at least 18 years old and have a minimum of one year’s professional experience in their current industry.
• Health insurance: Applicants must hold private health insurance providing coverage of at least ₩100 million for medical treatment and repatriation to their home country, maintained for the full duration of the visa.
• Clean criminal record: A clear criminal history is required for admission to the programme.

In terms of documentation, you will generally need: a valid passport (with at least six months’ validity beyond your intended stay), bank statements demonstrating consistent income — typically covering a six-month period — international health insurance with coverage applicable in South Korea, and a criminal record certificate issued within the previous six months.

Applications are submitted at the Korean embassy in your home country. Those already present in Korea may be eligible to switch from a visa-exemption entry (B-1), tourist visa (B-2), or short-term stay visa (C-3). Processing typically takes approximately 10 to 15 days.

One important caveat: the F-1-D visa is designed exclusively for individuals whose income comes from abroad. It does not confer the right to establish a Korean-registered company or take on Korean clients. Anyone planning to conduct business locally must pursue the D-8 entrepreneur visa route instead. Always confirm current requirements and applicable fees with the Korea Immigration Service or a Korean embassy before applying.

What taxes and social contributions apply to self-employed expats and business owners in South Korea?

South Korea applies a residence-based tax system. Residents are taxed on their worldwide income, while non-residents are liable only for income sourced within Korea. The residency threshold is significant: anyone who maintains a domicile in Korea or spends 183 days or more in the country during a tax year is treated as a tax resident.

For expats who have recently arrived, there is a notable transitional rule. During the first five years of tax residency, liability extends only to Korean-sourced income rather than global income. From the sixth year onwards, worldwide income comes into scope — an important consideration for long-term financial planning.

Personal income tax is levied on a progressive scale, with rates for individuals rising from a lower starting bracket to a maximum of 45% on the highest income bands. An additional local inhabitant surtax of 10% applies — not as a separate bracket, but calculated as 10% of the national income tax liability. Self-employed individuals and independent filers settle this amount alongside their national tax when filing in May. This arrangement bears some resemblance to how self-employed individuals in France pay both national income tax and local social charges, though the Korean mechanism operates differently. Always check the current rates and income brackets with the National Tax Service (NTS).

Corporate income tax also follows a progressive structure. National rates range from 9% to 24%, with a local income surtax applied on top, and a range of incentives is available for qualifying SMEs, start-ups, and R&D-intensive enterprises. Annual tax returns are due by 31 May. Once a company is established in South Korea, annual external audits become mandatory if total assets exceed USD $1 million.

VAT has broad application across the economy. The general rate is 10% on the supply of goods and services, though zero-rated VAT applies to exported goods, services delivered outside Korea, and certain services provided to non-residents in foreign currency. All VAT invoices must be submitted in electronic format; failure to do so results in penalties. Korea operates on a semi-annual VAT return cycle with preliminary quarterly filings, and the majority of filing and payment activity is handled electronically via the NTS HomeTax platform.

Social insurance obligations are compulsory for anyone employing staff, and self-employed individuals are generally required to enrol directly in the National Health Insurance and National Pension schemes. Unlike an employment context — where an employer handles contributions on the employee’s behalf — those working for themselves must register and remit contributions independently. The four mandatory insurance programmes are: National Pension, National Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance.

South Korea has concluded tax treaties with more than 90 countries, and these agreements can significantly influence your overall tax position, particularly in relation to overseas income and withholding tax obligations. Checking whether your home country has a treaty with Korea and consulting a qualified tax adviser for personal guidance is strongly recommended. The National Tax Service website publishes current rates, filing deadlines, and treaty details.

Are there any incentives, grants, or programmes to encourage expat entrepreneurs in South Korea?

Attracting foreign investment is a clearly stated policy priority for the South Korean government, which has implemented a wide range of incentive programmes and support mechanisms for foreign enterprises. Benefits available to eligible foreign businesses include tax exemptions, cash grants, and subsidies, with particularly favourable terms applying in designated Free Economic Zones and strategic commercial hubs. The country’s transparent legal environment and efficient incorporation processes further reinforce its appeal as a destination for international business.

Key initiatives include the following:

• Free Economic Zones (FEZs): Businesses established within FEZs may benefit from a full 100% corporate tax exemption for the first five years and a 50% reduction for the subsequent two years (as of 2025). FEZs are located in several parts of the country, including Incheon, Busan, and Gwangyang Bay. Qualifying enterprises also benefit from exemptions on income taxes and tariffs within these designated areas.
• Enhanced FDI incentives (from January 2025): The government introduced an expanded incentive package in January 2025 designed to draw additional foreign capital, incorporating cash subsidies covering up to 75% of eligible investment costs for designated projects such as R&D centres and regional headquarters, an extension of the tax relief period on imported capital goods from five to seven years, and new opportunity development zones outside greater Seoul offering corporate tax, acquisition tax, and property tax exemptions or reductions.
• SME and start-up tax relief: South Korea’s business environment is notably supportive of smaller enterprises. Qualifying SMEs are entitled to a tax deduction of between 5% and 30%, up to a ceiling of KRW 100 million, while newly established SMEs located outside metropolitan areas may receive a 50% to 100% corporate tax deduction for their first five years of operation (as of 2025).
• R&D tax credits: Companies undertaking eligible research activities can claim credits of up to 40% of qualifying expenditure (as of 2025).
• D-8-4 Technology and Startup Visa (OASIS): The D-8-4 is a points-based visa programme designed for individuals with advanced skills or intellectual property who intend to launch a business in South Korea. It provides an alternative route to the standard D-8 for applicants who may lack the full KRW 100 million investment capital but can demonstrate valuable technology or IP assets relevant to the Korean market.
• KOTRA support services: Invest Korea, administered by KOTRA, provides a free, one-stop service for foreign investors encompassing legal and regulatory guidance, investment consultation, and direct liaison with government bodies. This role is comparable to that performed by Enterprise Ireland or Germany Trade & Invest (GTAI) in their respective countries.

These programmes are subject to revision, so businesses should confirm current eligibility criteria, qualifying sector lists, and application requirements before committing any investment. The Invest Korea portal is the primary official source for up-to-date information on all available incentive schemes.

What are the practical challenges of being self-employed or running a business in South Korea?

Language barriers represent one of the most tangible obstacles facing foreign business operators. Despite South Korea’s genuine openness to foreign investment, legal and tax documentation remains entirely in Korean. Tax filings are prepared in Korean, although many service providers can offer assistance in other languages. Engaging a Korean-licensed tax accountant (세무사, semusa) or a company formation specialist is not merely advisable — for most expats, it is a practical necessity.

Professional local support is valuable at every stage of the business lifecycle. Establishing a company in South Korea means working through complex legal and regulatory requirements, and competent professional guidance is critical to maintaining compliance. The role of a semusa in Korea is broadly analogous to that of a gestor in Spain or a chartered accountant in Ireland — a licensed professional who manages official filings on your behalf. Factor in ongoing monthly fees for a semusa to handle your tax returns and payroll compliance.

Banking access can pose difficulties, especially during the initial setup period. Opening a corporate bank account as a foreign national requires your ARC, company registration documents, and in most cases a physical visit to the branch. The account registration process typically takes around two weeks, though incorporating the time needed to obtain necessary licences can push the total timeline closer to three weeks. Some banks have considerably more experience serving foreign clients than others — international institutions with Korean operations, such as Citi Korea or HSBC Korea, and major domestic banks including KEB Hana and Woori Bank, tend to be well-positioned to assist.

Invoicing and contract conventions in Korea differ significantly from practices in many other countries. Electronic tax invoicing is mandatory in most circumstances, and issuing or reporting e-invoices incorrectly can result in financial penalties. Business-to-business transactions generally require a tax invoice (세금계산서) submitted through the NTS’s electronic HomeTax system. Written contracts are the norm, and Korean-language versions carry legal primacy in the event of a local dispute.

Compliance deadlines require diligent management. Annual income tax returns fall due on 31 May of the following year, and missing this deadline triggers a rapid accumulation of penalties. VAT returns must be filed quarterly and corporate returns annually. In South Korea, compliance obligations are continuous, and failures can give rise to fines, audit proceedings, and operational restrictions.

Cultural expectations in business settings also differ notably from many other markets. Korean business culture places considerable weight on hierarchy, formal relationships, and the establishment of personal trust before commercial commitments are entered into. Expat founders who invest time in building networks — particularly through bodies such as the Seoul Global Center, the American Chamber of Commerce Korea (AMCHAM), or the European Chamber of Commerce in Korea (ECCK) — frequently find those connections invaluable for navigating both regulatory requirements and commercial realities.

Frequently asked questions

Can I be employed and self-employed at the same time in South Korea?

This depends entirely on your visa category. Most employment-based visas (E-series) restrict holders to working exclusively for their sponsoring employer, which means concurrent self-employment is generally not permitted without additional authorisation. F-series visa holders (F-2, F-4, F-5, F-6) typically benefit from broader work rights and may be able to combine salaried employment with self-employed activity. Check your specific visa conditions with the Korea Immigration Service before taking on any secondary business activity.

Do I need a Korean partner or co-founder to start a business?

In most cases, no. Foreign nationals are entitled to hold full ownership of a Korean company. However, certain restricted sectors may have specific ownership limitations. The majority of industries are fully open to 100% foreign ownership under South Korea’s Foreign Investment Promotion Law. Fields such as broadcasting, publishing, and parts of the financial services sector may carry specific restrictions — consult Invest Korea for a current list of sectors subject to limitations.

How do I handle invoicing foreign clients from South Korea?

When invoicing clients based outside South Korea for services supplied to non-residents, those transactions may qualify for zero-rated VAT treatment under Korean law. Zero-rating applies to exported goods, services delivered outside Korea, and certain services provided to non-residents in a foreign currency. You must still issue a proper tax invoice through the NTS HomeTax system and keep clear records of all transactions. A tax accountant can advise on whether your particular invoicing arrangement meets the criteria for zero-rating.

What happens to my business or self-employment status if my visa changes or expires?

Your entitlement to operate a business in South Korea is directly linked to your visa status. Should your visa expire or change to a category that does not cover your commercial activities, you must either cease those activities immediately or apply for a visa change to a suitable category — such as the D-8 for company founders. The Business Registration Certificate remains on record but does not in itself grant any right to remain in or work in Korea. If you are winding down a business, formal deregistration with the NTS is necessary to end ongoing tax filing obligations.

Is the Digital Nomad Visa the right route if I want to do business in South Korea?

The F-1-D Workation Visa is specifically intended for remote workers who earn their income from outside Korea. Holders may work remotely for overseas employers but are not permitted to engage in paid employment or commercially profitable activities within South Korea. If your plans include registering a company, billing Korean clients, or working for Korean employers, you will need a different visa — most likely the D-8 entrepreneur visa or an employment-linked E-series visa.

Do I have to pay Korean taxes on income earned from foreign clients while on the Digital Nomad Visa?

Tax residency in South Korea is established once a person has resided in the country for 183 days or more during a tax year, at which point all income is generally considered subject to local taxation. However, during the first five years of tax residency, liability is confined to Korean-sourced income only. For digital nomads whose earnings derive entirely from foreign sources, this can represent a meaningful financial advantage. Tax treaties between Korea and your home country may further reduce your exposure. Always seek advice from a tax professional with expertise in both Korean tax law and the obligations of your home jurisdiction.

What is the D-8-4 OASIS visa and who is it for?

The D-8-4 is a points-based visa programme targeting individuals with high-level skills or intellectual property who wish to establish a business in South Korea. It is tailored to tech founders and entrepreneurs who can demonstrate technological innovation or valuable IP, even where they cannot satisfy the standard KRW 100 million minimum capital requirement of the regular D-8 visa. Points are allocated based on qualifications, patents held, investment secured, and other relevant criteria. This visa is administered in collaboration with KOTRA; visit Invest Korea for current eligibility requirements and application guidance.

Are there English-language resources to help with business registration in South Korea?

Yes, a number of official and semi-official bodies provide support in languages other than Korean. Invest Korea (administered by KOTRA) offers English-language guidance, individual consultations, and complimentary assistance for foreign investors. The Seoul Global Center provides business advisory services and support to foreign nationals based in Seoul. The NTS HomeTax portal includes some English-language navigation, and the NTS operates a consultation helpline reachable by dialling 126 from within Korea. For complex or high-stakes matters, engaging a certified Korean tax accountant (semusa) or a business law firm remains the most dependable course of action.
