Start a Business in Korea as a Foreigner: Legal Steps & Costs
Start a Business in Korea as a Foreigner: Legal Steps & Costs
Most foreigners who want to start a business in Korea hit the same wall: they find either a cheerful government brochure that skips the hard parts, or a forum thread from 2019 that's no longer accurate. Neither helps you actually file the paperwork.
This guide covers the real process — company structure, visa pathways, registration timeline, banking, taxes, and the compliance traps that catch first-timers. It assumes you're already in Korea or planning to be, and that you want to move from "thinking about it" to "registered and operational."
What's covered: entity types and which one foreigners usually choose, visa options including the D-8-4 Start-up Visa (formerly referenced as D-2-1 in some older materials — verify your current category with the Korea Immigration Service), the actual 7–14 day registration sequence, first-year tax and accounting obligations, and honest cost estimates throughout.
Disclaimer: This is not legal advice. Immigration law and tax rules change annually. Confirm current requirements with the Seoul Global Center or a licensed Korean accountant (세무사) before filing anything.
Why Foreigners Can Register a Business in Korea (And Common Myths)
Starting a business in Korea as a foreigner is legally straightforward. The Korean Commercial Act (상법) does not prohibit foreign nationals from incorporating, owning 100% of shares, or serving as sole representative director. The real gating factor — the one almost every glossy guide buries — is visa status, not corporate law.
Myth: You Need a Korean Co-Founder
You do not. This myth likely originated from the era when some business types required a local representative for practical licensing reasons, and it stuck. Today, a foreigner can be the sole shareholder and sole director of a Korean LLC (유한회사) or stock company (주식회사). No Korean name on the incorporation documents is required.
What you do need is a business address — a real one, not a P.O. box — and a Korean corporate seal (법인 인감). Coworking spaces in Mapo-gu, Gangnam-gu, and Seongdong-gu routinely provide registered address services; as of 2026, market rates typically run ₩50,000–150,000/month, though prices vary by district and provider. That's your Korean co-founder substitute.
The Actual Legal Reality and Visa Pathways
Korean law requires that the representative director have legal status to work and reside in Korea. If you're already on an E-7 (특정활동, specific activities), F-2 (거주, long-term residence), F-5 (영주, permanent residence), or F-6 (결혼이민, marriage migrant) visa, you can incorporate and operate without a dedicated business visa. If you're on a tourist visa (B-1 or B-2) or have no status yet, you'll need to solve the visa problem first — before or alongside registration.
The most relevant visa categories for new foreign founders are covered in the next section.
Choose Your Business Structure (LLC vs. Branch vs. Freelance)
Korea offers several legal structures. Most foreign founders end up with one of two options.
Jushik Hoesa (주식회사, Stock Company) — When to Use It
The 주식회사 is Korea's dominant corporate form and what most people picture when they think "Korean company." Under the Korean Commercial Act (상법), the statutory minimum paid-in capital is ₩100 — legally, though practically investors and banks want to see substantially more. It requires at least one director and is publicly listed on the corporate registry.
Use this structure if you're raising investment from Korean VCs, planning to list eventually, or need the credibility signal that comes with a 주식회사 designation. It has more ongoing compliance overhead — annual general meetings, board resolutions, and public disclosure requirements.
Yuhan Hoesa (유한회사, LLC-Equivalent) — The Foreigner-Friendly Default
The 유한회사 is the structure most foreign founders should default to. Members have limited liability. There's no requirement for public disclosure of internal shareholder agreements. It requires fewer annual filings than a 주식회사, and it can be structured with a single member (you). The statutory minimum capital is also ₩100 under the Korean Commercial Act (상법), Articles 553–594, though as with the 주식회사, verify current requirements directly — minimums and thresholds are subject to legislative revision.
For a solo foreign founder bootstrapping a consulting, software, or services business, the 유한회사 is cleaner and cheaper to maintain.
Branch Office vs. Independent Contractor Status
If you work for a foreign company and want to establish a Korean presence, a branch office (지점) may be more appropriate than incorporating a new entity. A branch is not a separate legal entity — liability flows back to the parent. Setup is faster but your operational scope is limited to what the parent company does.
Sole proprietorship (개인사업자) is the lowest-barrier option: register as an individual business operator rather than a corporation. No minimum capital, simple 사업자 등록 process, lower accounting overhead. The downside: unlimited personal liability, and some visa categories don't allow it. Also, if your annual revenue crosses certain thresholds, the tax treatment becomes less favorable than a corporate structure.
Visa Sponsorship: Which Path Works for You
This is where most guides hand you a list of visa names and leave. Here's what those names actually mean in practice for foreign founders.
Startup Visa — The Dedicated Path
Korea's dedicated entrepreneurship visa for foreign founders — administered through the Korea Immigration Service (출입국·외국인정책본부, immigration.go.kr) — has historically been referenced as the D-8-4 (기업투자) category or, in some program materials, as the D-2-1 (창업비자). Visa sub-type codes and program structures are periodically revised by the Ministry of Justice (법무부); confirm the current category designation with the Korea Immigration Service or the Seoul Global Center before applying.
Requirements as of recent program guidelines include: a viable business plan, demonstrated capital (the threshold has varied year to year; confirm the current amount with the Korea Immigration Service or the Seoul Global Center), and approval from a designated incubator or accelerator in some application tracks. The visa is typically issued for one year initially and renewed based on business performance — revenue, employment, and investment milestones matter at renewal time.
The Seoul Global Center (seoulglobalcenter.kr) offers free consultation for foreign founders and can help you assess whether your business plan meets the current bar before you apply.
D-10 (Job Seeker) to Startup Visa Transition
The D-10 (구직, job seeker) visa gives you time in Korea to explore employment or business options — it's not a work visa in itself. Some founders arrive on a D-10, use the period to set up their legal entity and business plan, then apply for the relevant startup visa category. This transition is possible but not guaranteed; you need to show the business is real and operational, not just incorporated.
For a deeper dive into D-2, D-10, and self-employment visa tiers, see our [korea-visa-options-foreign-workers-2024] guide.
Self-Employment Visa Subtypes and Their Limits
Certain D-10 subtypes allow limited self-employment activity. These are not full business operation visas. You generally cannot employ staff under such subtypes, and the business types permitted are restricted. Do not confuse a job-seeker sub-category with a dedicated entrepreneurship visa. If you intend to build a company with employees or significant operations, a self-employment-only sub-visa will be an obstacle, not a solution. Verify current sub-type permissions directly with the Ministry of Justice (법무부).
Registration & Documentation (The Real Timeline)
Over the past decade I've helped several foreign-founded companies — European SaaS teams, North American consultancies, a Southeast Asian logistics startup — navigate this exact process from the Korean side. What I've consistently seen is that the paperwork itself isn't the hard part. In one case, helping a French software team get their 유한회사 registered in 2018, the actual court filing took four days. The two weeks before that were spent fixing a mismatch between the registered address on the articles of incorporation and the coworking space lease documentation. The system is precise; preparation is what saves you time, not speed once you're at the counter.
The actual business registration process in Korea, once your visa and documents are sorted, runs 7–14 business days if your paperwork is complete the first time. Most delays come from avoidable errors.
Pre-Registration: Business Name Check
Start with a business name availability check through the Supreme Court Registry's legal entity search portal (인터넷등기소, iros.go.kr). Korean corporate names must be unique within the same registry district, not nationally — so "Seoul ABC 유한회사" and "Busan ABC 유한회사" can coexist. Pick your name, draft your articles of incorporation (정관), and get your corporate seal (법인 인감) made — any seal shop near a district court does this; as of 2026, typical cost ranges from approximately ₩30,000–60,000, though verify locally.
Corporate Registration with the Court (등기소)
File your incorporation documents at the district court registry office (등기소) nearest your registered business address. You'll submit: articles of incorporation, shareholder list, capital deposit certificate (from a bank), and the representative director's identification. The court issues your corporate registration number (법인등록번호) within approximately 3–5 business days.
Court registration fees are calculated at roughly 0.4% of registered capital, with a statutory minimum; the minimum has been reported at around ₩112,500, but verify the current fee schedule at iros.go.kr before filing, as fee schedules are updated periodically.
Tax ID and Bank Account Setup
With your corporate registration number, apply for a business registration number (사업자 등록번호) at the local tax office (세무서) or online via the National Tax Service's Hometax portal (hometax.go.kr). The application form is the 사업자 등록 신청. Processing typically takes 2–3 business days.
Once you have both numbers, open your corporate bank account. Banks require the corporate registration certificate (법인등기부등본), business registration certificate (사업자등록증), and the representative director's passport and ARC (Alien Registration Card, 외국인등록증). Expect to visit the branch in person — online-only account opening for foreign-operated entities is not consistently available as of 2026.
What Most Guides Get Wrong: Hidden Costs & Compliance Traps
Accounting and Tax Filing Expectations (You Cannot Skip This)
A Korean corporation must file financial statements regardless of revenue. Zero revenue does not mean zero filing obligation. Korean corporate accounting follows K-IFRS (한국채택국제회계기준) or K-GAAP (일반기업회계기준) standards; your receipts-in-a-shoebox approach from freelancing will not survive a tax audit.
At minimum, you need periodic VAT filings (if VAT-registered; general taxpayers file twice yearly, simplified taxpayers once yearly — confirm your registration category), monthly payroll withholding reports (if you pay yourself a salary), and an annual corporate tax return. The 세무신고 (tax filing) calendar is non-negotiable. Miss a deadline and you pay a late penalty — according to the National Tax Service (국세청, nts.go.kr), the standard underpayment penalty is 20% of the unpaid tax amount, plus daily interest accrual. Confirm current penalty rates at nts.go.kr, as these are subject to revision.
Employment Insurance and Health Insurance Thresholds
The moment you put yourself on payroll as an employee of your own company — which many founders do to formalize their income — you trigger National Health Insurance (국민건강보험, NHI) and employment insurance (고용보험) enrollment obligations. According to publicly reported rate schedules, the combined employer and employee contribution burden has run in the range of approximately 15–18% of reported salary, though rates are adjusted annually; verify the current year's contribution rates with the National Health Insurance Service (국민건강보험공단, nhis.or.kr) and the Korea Employment Insurance Service (고용보험, ei.go.kr) before running payroll.
For detail on how employment insurance and payroll obligations change when you hire your first employee, see [hiring-first-employee-korea-foreigner].
Year-End Settlement and the Most Common Mistakes
The year-end tax adjustment (연말정산) applies to employees; the corporate tax return (법인세 신고) applies to the entity. Foreign founders frequently conflate these two processes or miss that both may apply if they draw a salary. The corporate tax return is due within 3 months of your fiscal year end — most Korean companies use a December 31 fiscal year, making the deadline March 31 of the following year.
The second-most common mistake: failing to register for VAT at the right time. As of 2026, service businesses crossing the ₩48 million annual revenue threshold are generally required to register as general VAT taxpayers; if you were operating below that threshold and cross it mid-year, back-reporting obligations may apply. Confirm the current threshold and back-registration rules with the National Tax Service (국세청) or your 세무사, as thresholds are periodically adjusted.
First-Year Taxes, Banking, and Accounting Setup
Corporate Tax vs. Income Tax Filing
According to publicly available National Tax Service (국세청) rate tables, Korean corporate tax rates for small companies have run approximately 9% on taxable income up to ₩200 million, and 19% on the portion between ₩200 million and ₩20 billion (additional brackets apply above that). These rates are subject to legislative revision; verify current corporate tax brackets at nts.go.kr before filing.
If you draw a salary from your company, that salary is taxed separately as personal income (소득세) under the global income tax schedule. You cannot skip one by relying on the other.
Opening a Business Bank Account
The major banks — Shinhan (신한은행), KB Kookmin (KB국민은행), Woori (우리은행), and IBK Industrial Bank of Korea (기업은행) — all serve corporate accounts. IBK has historically been noted by the foreign founder community as relatively accessible for small business accounts and offers English-language support at designated branches. Expect to spend 1–2 hours at the branch on your first visit; service levels and English availability vary by branch.

Hiring an Accountant (세무사) vs. DIY: Realistic Costs
A basic 세무사 (licensed tax accountant) retainer for a small Korean LLC runs ₩1.5M–3M per year for routine filings, based on current market rates. Full-service accounting with payroll processing typically runs ₩3M–6M annually. These are not luxury prices for Korean business services — they are the market rate as of 2026, though individual firms vary.
DIY is possible using Hometax and the National Tax Service's foreigner-language resources, but the time cost is substantial and the error rate for first-timers is high. The math usually favors hiring a 세무사 by year two once compliance complexity compounds.
Funding, Immigration, and Scaling
Government Grants and Support Programs for Foreign Entrepreneurs
KOTRA (Korea Trade-Investment Promotion Agency, 대한무역투자진흥공사), the Ministry of SMEs and Startups (중소벤처기업부), and local Seoul Metropolitan Government programs all offer grants and soft loans for small businesses — including foreign-owned ones. Program details, eligibility criteria, and funding amounts are published annually; consult KOTRA's Invest Korea portal (investkorea.org) and the Ministry of SMEs and Startups (mss.go.kr) for current program cycles.
The Seoul Global Center runs periodic information sessions specifically for foreign founders on accessing these programs. Grant amounts for early-stage ventures have ranged from ₩10M to ₩100M+ depending on the program, sector, and evaluation score, though funding levels vary by annual budget cycle. Competition is real; a Korean-language business plan will significantly improve your application score.
How Business Performance Ties to Visa Renewal
Your startup visa renewal is evaluated against your business's actual performance — revenue, headcount, and investment received all factor in. There are no published bright-line thresholds, but immigration officers look for evidence the business is real and growing. A company with zero revenue, zero employees, and zero customers after 12 months is a renewal risk.
Document everything: invoices, contracts, bank statements, client communications. The renewal application is essentially a business review.
When to Bring in Co-Founders or Employees
Adding a Korean co-founder or employee changes your compliance picture substantially — payroll, insurance, and labor law obligations all activate. Do not hire before you understand the cost. The break-even point for hiring vs. contracting in Korea is higher than most Western founders expect.
Frequently Asked Questions
Can foreigners actually own 100% of a Korean company?
Yes. The Korean Commercial Act (상법) places no nationality restriction on company ownership or directorship. A foreign national can be the sole shareholder and sole representative director of a Korean 유한회사 or 주식회사. Restrictions do exist in specific regulated industries — broadcasting, certain defense-related sectors, and a few others listed under the Foreign Investment Promotion Act (외국인투자 촉진법) — but for most businesses a foreigner faces no ownership ceiling. The practical gate is visa status: you need legal authorization to reside and work in Korea, not a Korean name on the corporate register.
How long does it actually take to register a business in Korea?
The court registration step takes approximately 3–5 business days; the tax registration step takes approximately 2–3 business days. End-to-end from submitting your first document to receiving your 사업자등록증, budget 7–14 business days assuming your documents are correct and complete. Most delays come from one of three sources: incorrect articles of incorporation, a mismatch between the registered address documentation and the actual address, or bank delays in issuing the capital deposit certificate. If you've done this before or hired a legal agent (법무사), the process moves faster.
Do I need Korean language skills to start a business here?
Not legally — registration forms exist in English at some agencies, and the Seoul Global Center can assist. But practical necessity scales with your business type. A B2B software company serving global clients can function with minimal Korean. A retail business, restaurant, or any operation requiring local vendor relationships, permits, or Korean-speaking staff will struggle without at least conversational Korean or a bilingual partner. The tax and legal system is still overwhelmingly Korean-language; your 세무사 becomes a critical language bridge.
What happens to my business if my visa expires?
The business entity does not automatically dissolve — the corporate registration remains on file regardless of your visa status. But you lose the legal right to operate it from within Korea. You cannot sign contracts, manage employees, or conduct business activities as a representative director while out of status. Visa renewal tied to a startup visa category is evaluated against business performance, so letting your visa lapse while the company is underperforming creates a compounding problem: you may not qualify for renewal, and the business cannot legally operate without you in-country. Consult the Korea Immigration Service (출입국·외국인정책본부) or a licensed immigration attorney immediately if you're approaching expiry.
Is it cheaper to hire a lawyer/accountant or DIY the registration?
DIY registration is possible and costs roughly ₩300,000–500,000 in court fees, seal costs, and incidentals as of 2026 — verify current fee schedules before budgeting. A legal agent (법무사) or lawyer handling the incorporation charges approximately ₩500,000–2,000,000 depending on complexity. For ongoing accounting, a 세무사 retainer costs ₩1.5M–3M/year — which sounds expensive until you compare it to a missed VAT deadline (20% penalty plus interest) or an incorrectly filed corporate return requiring amendment. The break-even calculation usually favors professional help by year two. In year one, if you have a simple structure and time to learn the system, DIY is survivable.
What to Do Next
Pick your entity type and check your visa status today — those two decisions gate everything else. If you're unsure about your visa eligibility for the startup visa pathway, book a free consultation with the Seoul Global Center before spending money on incorporation. They will tell you directly whether your business plan qualifies, which saves you weeks of guesswork.
Once you know your path, the 7–14 day registration timeline is real and achievable. The complexity is in the preparation, not the filing.
