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, provided it stays clear of Korea’s worker dispatch rules.
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: ownership sits in units of contribution held by members, there is no board requirement, and the statutory auditor is optional. Units have been freely transferable under Commercial Act Article 556 since the amendment took effect in April 2012, subject to whatever the articles say. 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, above all because a yuhan hoesa director has no statutory three-year term and so avoids the re-appointment registration a stock company files every cycle.
Two older selling points for the form have expired. Korean tax treatment is identical for both forms, so the tax difference that matters is how the foreign parent classifies the entity at home, which for a US parent runs through the check-the-box regulations. Disclosure relief closed in 2018: the Act on External Audit of Stock Companies, etc. was amended effective 1 November 2018 to bring limited companies inside its scope, and once a company is caught the audit and DART disclosure obligations are the same for both forms. Only the trigger test differs, at three of five secondary criteria for a yuhan hoesa against two of four for a jusik hoesa. The full comparison, including the conversion trap and the US election, is in the guide to yuhan hoesa vs jusik hoesa.
The choice has audit-threshold, governance, and home-country classification 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 70,000 to 75,000 at prevailing 2026 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 figures from the Ministry of Trade, Industry and Resources, the ministry known in English as the Ministry of Trade, Industry and Energy until the October 2025 government reorganization, 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 two to four weeks with complete documents. You will need a Korean registered address; serviced offices and, for qualifying companies, Free Economic Zone facilities both work. The formats, the tax office site check, and the Seoul registration tax surcharge are compared in Choosing a Registered Address That Clears the Tax Office.
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, and most require in-person appearance by the representative director. Bring more documentation than you think you need, and work the order, the two accounts, and the document pack through the guide to the corporate bank account in Korea.
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 and runs alongside the entity work rather than after it. 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.
Choosing a Registered Address That Clears the Tax Office
A registered office in Korea faces two tests from two authorities. The commercial registry needs a head office location for the articles and the register, and nothing in the Commercial Act or the Commercial Registration Act sets a floor area, exclusive use, or occupancy requirement. The district tax office applies the Value-Added Tax Act, which defines a place of business as a fixed place where the company conducts all or part of its transactions. Address choices fail at that second test.
Korea sells two products under the English phrase “virtual office.” A 비상주 사무실 provides an address and mail handling with no assigned space. A 공유오피스 assigns a desk or a numbered unit under an occupancy agreement in the company’s name. Both usually clear the registry. Only the second produces the lease and floor plan that Article 11(3) of the VAT Act Enforcement Decree asks for, and the site check (현장확인) the district office runs is routine, especially at addresses shared by dozens of companies. Banks treat an obvious mail-forwarding address as a due diligence signal, and the D-8 change-of-status application lists an office lease. Licensed industries such as food service and clinics need qualifying premises regardless. Check the building register (건축물대장) before signing, because a unit whose registered use does not cover the activity is a common and avoidable failure.
Location also carries a tax. Article 28(2) of the Local Tax Act triples registration and license tax inside the overconcentration control region, which covers all of Seoul. Incorporating there on KRW 100 million costs KRW 1.2 million against a standard KRW 400,000, plus local education tax at 20 percent of that amount, and any capital increase within five years of incorporation is surcharged the same way. Price any planned increase before choosing the district.
Taxes: What a Foreign-Owned Company Pays
Corporate income tax runs in four national brackets of 10, 20, 22, and 25 percent of taxable income, plus local income tax on top of the national liability, for fiscal years beginning on or after 1 January 2026 under Korea’s 2025 tax reform, which the Ministry of Finance and Economy framed as a return to the 2022 rates, as PwC Worldwide Tax Summaries and Acclime Korea also record. The previous schedule ran at 9, 19, 21, and 24 percent. Most foreign subsidiaries in their early years sit in the lower brackets. The filing calendar, withholding on payments to the parent, and transfer pricing exposure are worked through in the guide to Korean corporate tax for foreign-owned companies.
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 (4.75 percent of salary from the employer, matched by the employee, in 2026, 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 both corporate forms carry the same obligations once caught; the trigger test differs, at two of four secondary criteria for a stock company against three of five for a limited company. 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. One filing belongs ahead of that calendar instead of inside it, because Korea runs first to file on trademarks and the registry does not wait for your incorporation: the timing, the official fees, the hangul question and the routes back from a squatted mark are set out in Filing the Korean Trademark Before the Entity. None of this is exotic; all of it punishes improvisation.
Filing the Korean Trademark Before the Entity
Korea registers trademarks to whoever files first. Article 35(1) of the Trademark Act gives the mark to the earlier applicant, and foreign sales history creates no Korean right on its own. The Paris Convention priority claim under Article 46 helps only if the Korean application follows the home filing within six months, a window that usually closes while the Korea plan is still under discussion.
The filing is cheap. Official fees run KRW 52,000 per class to file electronically, or KRW 46,000 where every designated good comes from the office’s published product-name list, and KRW 201,000 per class to register for ten years. A foreign company with no Korean address must file through a Korean patent attorney, whose fee is separate. Korea’s government indicator service put average first-action pendency at 11.9 months in 2025, so plan on about a year before the examiner responds.
File the hangul transliteration you will actually use as a separate application at the same time. Korean buyers and marketplaces handle a foreign brand in hangul, and adding it to a pending Latin application later counts as a material change.
Use matters after registration. Under Article 119(1)3 anyone can seek cancellation of a mark unused in Korea for three continuous years, and the registrant carries the burden of proving use. Limit classes to products you will ship within three years.
If a distributor or broker has already filed your mark, recovery is possible. Article 34(1) subparagraphs 13, 20, and 21 cover bad-faith filings that exploit foreign reputation or a business relationship, and invalidation on those grounds carries no five-year bar. A squatted mark registered over three years ago and never used is usually cheaper to attack through non-use cancellation. Once registered, record your mark with the Korea Customs Service so suspect imports are flagged.
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, where the dependable benefits are rent and site support on long public leases, customs duty relief on imported capital goods, and dedicated administrative help. The national corporate income tax reduction closed to new applications on 31 December 2018, and cash grants are a Foreign Investment Promotion Act instrument that zone status alone does not confer, so price a zone on land and operations. What each zone actually confers, who qualifies as a principal tenant company, and which reliefs remain open are set out in the guide to Korea’s free economic zones. 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 that the account cannot open until the registry and the district tax office have both issued their certificates, with the representative director present in person. 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, roughly USD 70,000 to 75,000 at prevailing 2026 rates, 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.
