Starting a business in South Korea as a foreign company means making four decisions in the right order: whether you need a Korean entity at all, which entity type fits, whether to structure the investment for recognition under Korea’s Foreign Investment Promotion Act, and who relocates on what visa. The paperwork itself is faster than most executives expect. A foreign-owned corporation can go from documents to a registered, bank-ready company in roughly one quarter. What takes longer is everything the entity exists to do, which is why the entity decision should follow your market entry strategy, not lead it.
This guide covers the operational layer: entities, the foreign direct investment process, registration steps, visas, taxes, and employment compliance. For the strategic layer above it, which entry model fits your situation and when an entity is premature, start with the Korean market entry strategy guide.
Do You Actually Need a Korean Entity?
Not always, and the honest answer saves money. You can sell into Korea through a distributor or agent with no entity at all, which is the standard path for industrial products. You can test consumer demand through cross-border e-commerce. You can even employ one or two people through an employer-of-record arrangement while validating the market.
You need your own entity when you want to invoice domestically, hire directly at scale, sponsor visas, claim foreign investment incentives, sign leases, or present as a domestic counterpart to Korean enterprise and government customers. If your business case for Korea has cleared those thresholds, or the economics of doing business in Korea require permanent presence in your sector, the rest of this guide is the map.
Which Entity Type Fits: Jusik Hoesa vs Yuhan Hoesa
Foreign investors setting up a Korean corporation choose between two forms under the Korean Commercial Act.
Jusik hoesa (stock company) is the standard Korean corporation: shares, a board structure, and the governance machinery to add shareholders or raise capital later. It is the form Korean counterparties know best, and for companies that may bring in Korean investors, issue equity to employees, or scale into a large local operation, it is the default choice. The governance obligations are heavier, and larger stock companies cross into statutory audit and board composition requirements as they grow.
Yuhan hoesa (limited company) is the simpler form: membership interests instead of freely transferable shares, lighter governance, no board requirement, and fewer disclosure obligations. For a wholly owned subsidiary that will never seek outside Korean investment, which describes most foreign subsidiaries, the yuhan hoesa is usually the cleaner instrument. Many multinational subsidiaries in Korea use it precisely because it keeps administration light.
The choice has tax, audit, and flexibility implications specific to your structure, and it is one of the few places in this process where an hour with a Korean corporate lawyer pays for itself. The two other structures, branch offices and liaison offices, serve narrower purposes: a branch is a revenue-generating extension of the foreign parent registered under the Foreign Exchange Transactions Act, and a liaison office is a non-revenue presence for research and coordination. Both are covered in the entry-model comparison in the market entry strategy guide.
FDI Recognition: Why the KRW 100 Million Threshold Matters
Korea’s Commercial Act, since its 2009 amendment, imposes no meaningful general minimum capital on corporations. But there is a threshold that matters enormously for foreign founders: recognition as a foreign-invested company under the Foreign Investment Promotion Act requires an investment of at least KRW 100 million (roughly USD 75,000 at recent rates) with the foreign investor holding at least 10 percent of voting shares.
FDI recognition is worth structuring for. It is the basis for the D-8 investor visa that lets founders and executives relocate. It opens eligibility for investment incentives, including the tax credits and support programs administered through InvestKOREA and, for larger projects, the benefits attached to Free Economic Zones. And it places the investment inside Korea’s formal FDI framework, with the guarantees on remittance of profits and repatriation of capital that the Act provides. Korea recorded roughly USD 36 billion in FDI commitments in 2025, per Ministry of Trade, Industry and Energy figures, and the government’s posture toward qualifying foreign investment is actively welcoming.
Foreign ownership can be 100 percent in the large majority of industries. Korea maintains a short negative list of restricted and partially restricted sectors (broadcasting, certain agriculture, some energy and transport categories), so confirm your industry code before structuring, but for marketing, technology, trade, and most manufacturing-adjacent businesses, full foreign ownership is standard.
The Registration Process, Step by Step
The sequence below is for a foreign-invested corporation, the most common path. Timelines reflect what corporate service firms operating in Korea publish and match what the process looks like in practice when documents are complete.
Step 1: Foreign investment notification. Before money moves, the investment is notified through a foreign exchange bank or KOTRA. This is a filing, not an approval, for non-restricted industries, and it typically takes days.
Step 2: Capital remittance. The investment capital is wired from the foreign investor to Korea and converted, creating the paper trail that the FDI framework and later registrations rely on. Wire it from the entity or person named in the notification; mismatches here cause the delays people blame on bureaucracy.
Step 3: Incorporation registration. The company is registered with the commercial registry through the court system: articles of incorporation, director appointments, registered address, and seal registration. This step generally takes one to two weeks with complete documents. You will need a Korean registered address; serviced offices and, for qualifying companies, Free Economic Zone facilities both work.
Step 4: Business registration certificate. Within 20 days of starting business, the company registers with the district tax office and receives its business registration number, the identifier used on every invoice and contract in Korea. In practice this follows incorporation within days.
Step 5: Foreign-invested company registration. After incorporation and capital injection, the company completes its FDI registration, formalizing its status under the Foreign Investment Promotion Act.
Step 6: Corporate bank account. Korean banks apply genuine scrutiny to foreign-owned entities under anti-money-laundering rules. Account opening typically takes two to four weeks and requires in-person appearance by the representative director at most banks. Bring more documentation than you think you need.
Step 7: Visa. With FDI registration in place, founders and relocating executives apply for the D-8 investor visa, which commonly takes one to three months to process. Staff hired from abroad use employment visa categories (E-7 for specialists), each with their own requirements.
End to end, plan roughly one quarter from decision to a fully operational entity with banking and a visa, consistent with the timeline framing in the market entry strategy guide. The registration is the fast part.
Taxes: What a Foreign-Owned Company Pays
Corporate income tax runs in four national brackets from 9 to 24 percent of taxable income, plus local income tax of roughly ten percent of the national liability, per National Tax Service rates in effect since the 2023 revision. Most foreign subsidiaries in their early years sit in the lower brackets.
Value-added tax is 10 percent, filed quarterly for corporations. Registration is automatic with the business registration certificate, and Korean invoicing runs on the electronic tax invoice system, which your accountant will live in.
Registration and license taxes apply at incorporation and on capital increases, and they are levied at higher rates inside the Seoul metropolitan overconcentration control area, which is one financial reason some companies register outside central Seoul.
Withholding and treaties. Dividends, interest, and royalties paid to the foreign parent face Korean withholding, moderated by Korea’s wide tax treaty network. Structure the parent-subsidiary flows with treaty rates in mind from day one rather than retrofitting.
Korea’s tax administration is electronic, strict on documentation, and entirely navigable with a competent local accounting firm, which a foreign-owned company should engage before its first transaction, not its first filing.
Employment: The Rules That Surprise Foreign Employers
Hiring in Korea comes with a statutory framework that foreign employers need priced in from the first offer letter.
Severance is mandatory. Under the Employee Retirement Benefit Security Act, employees who complete a year of service accrue severance equal to roughly one month of average wages per year worked, paid at departure or funded through a retirement pension plan. Severance is set by statute, and it belongs in your cost model as roughly an extra month of salary per employee per year.
Working hours are capped. The Labor Standards Act limits work to 52 hours per week (40 regular plus 12 overtime), with real enforcement and penalties.
Four social insurance schemes are mandatory: national pension (4.5 percent of salary from the employer, matched by the employee, under the National Pension Act), national health insurance, employment insurance, and industrial accident compensation insurance. Combined employer-side contributions add a meaningful percentage on top of gross salary; budget for roughly ten percent before benefits.
Termination is hard. Korean law requires just cause for dismissal, and the practical bar is high. Probation periods, documented performance management, and carefully drafted employment contracts matter far more in Korea than in at-will jurisdictions. Get the employment contract template right before the first hire, in Korean, reviewed by Korean counsel.
The Compliance Calendar After Day One
A Korean corporation lives on a rhythm of filings: quarterly VAT, annual corporate income tax within three months of fiscal year end, payroll withholding monthly, and the four insurance schemes running continuously. External audit obligations attach as companies cross asset and revenue thresholds, and stock companies face them earlier than limited companies of similar size. Sector rules layer on top: product certifications under the KC mark regime for regulated goods, K-REACH for chemicals, and PIPA, Korea’s data privacy law, for any company handling Korean personal data. None of this is exotic; all of it punishes improvisation.
Where to Register: Seoul, the FEZs, or Elsewhere
The registered address is a real decision, not a formality. Seoul is where the talent, clients, and agencies are, and for a marketing, SaaS, or services entity, a Gangnam or CBD serviced office is the pragmatic default despite the higher registration taxes inside the overconcentration control area. Companies with industrial, logistics, or R&D operations should look at Korea’s Free Economic Zones, which offer qualifying foreign-invested companies tax reductions, cash grants for larger projects, site support, and dedicated administrative help; Incheon (adjacent to the airport and Songdo’s international business district) and Busan-Jinhae are the ones foreign companies use most. Semiconductor-adjacent suppliers increasingly weigh proximity to the fab corridors instead: Pyeongtaek, Yongin, Icheon, and Cheongju put you inside your customers’ daily radius, which matters in a relationship-driven procurement culture. The rule of thumb: register where your customers and team actually are, and let the tax tail wag the dog only when incentives are large and your operation is genuinely mobile.
Where to Get Help
Korea invests real institutional effort in foreign founders, and the free layer is worth using before you pay anyone. InvestKOREA, KOTRA’s investment promotion arm, provides consultation, FDI procedure guidance, and for qualifying investors office space and administrative support through its Investment Plaza. The Seoul Global Business Support Center offers free consultations on incorporation, visas, tax, and labor specifically for foreign entrepreneurs. The Free Economic Zone authorities run their own one-stop services for companies locating there. Layer the paid professionals on top: a Korean corporate law firm for entity setup and the employment contract template, and an accounting firm engaged before the first transaction. The combination of free institutional support plus two good local firms covers everything in this guide for a fraction of what companies burn trying to run Korean administration from headquarters.
Common Mistakes Foreign Founders Make
Incorporating before the strategy exists. The entity is a container. Registering one because it feels like progress, before the entry model and budget are settled, produces a compliant shell with no market plan and a burn rate.
Choosing jusik hoesa by default. The stock company is not automatically right for a wholly owned subsidiary; plenty of foreign parents carry governance overhead they never needed because nobody asked about yuhan hoesa.
Underestimating the bank account step. Companies book flights around incorporation and forget the account takes two to four weeks with an in-person representative director appearance. Sequence the trip around the bank, not the registry.
Copying a home-market employment contract. At-will language, missing severance mechanics, and untranslated contracts create liabilities Korean labor authorities and courts will not read your way.
Skipping FDI structuring to save time. Wiring capital informally, below the KRW 100 million threshold or outside the notification process, forfeits the visa path and incentive eligibility and is expensive to unwind.
Frequently Asked Questions
Can a foreigner own 100 percent of a Korean company? Yes, in the large majority of industries. Korea permits full foreign ownership except in a short negative list of restricted sectors under the Foreign Investment Promotion Act. Marketing, technology, trading, and most B2B service businesses are fully open, and 100 percent foreign-owned subsidiaries are the norm among international companies operating in Korea.
What is the minimum capital to start a business in Korea? The Commercial Act imposes no meaningful general minimum for a corporation. The number that matters is KRW 100 million, about USD 75,000, which is the minimum investment for recognition as a foreign-invested company under the Foreign Investment Promotion Act, the status that unlocks the D-8 investor visa and FDI incentives.
How long does it take to register a company in Korea? Incorporation itself generally takes two to four weeks with complete documents, per timelines published by corporate service firms operating in Korea. A realistic end-to-end plan, including FDI notification, capital remittance, the corporate bank account, and a D-8 visa, is about one quarter.
Do I need to live in Korea to run a Korean company? No. A Korean corporation needs a representative director, but that person is not required to be a Korean resident, and many foreign subsidiaries operate with a nonresident representative plus a local manager. Practically, banking, hiring, and customer relationships all run better with someone senior on the ground, which is why founders who are serious about Korea usually structure for the D-8 and relocate or split time.
Setting It Up Right
Starting a business in South Korea is a solved problem administratively. The registration is fast, the FDI framework is welcoming, and the professional infrastructure (corporate lawyers, accounting firms, KOTRA support) is excellent. What separates the foreign companies that get value from their Korean entity from the ones that get a compliance burden is everything around the paperwork: entering with the right model, funding year one realistically, and building the market presence the entity exists to serve. Sequence those three correctly and the Korean entity becomes what it should be: the operating base for a durable business rather than a box on a checklist.
