How to Register an LLC in Korea: A Step-by-Step Guide for Foreigners
How to Register an LLC in Korea: A Step-by-Step Guide for Foreigners
Most guides about registering a Korean LLC are written by accountants who want you to hire them, or by bloggers who've never actually done it. They promise a "5-day process" and then leave out the three weeks you'll spend waiting for a bank account you can't open until you have the registration number you can't get without the address you haven't secured yet.
This article maps the actual sequence — the dependencies, the government offices, the real costs, and the points where foreign founders consistently get stuck.
What's covered: entity type selection, pre-registration checklist, the court-to-tax-office process step by step, realistic timeline, costs, and post-registration compliance.
Do You Actually Need an LLC in Korea?
Before you start filing paperwork to register an LLC in Korea, it's worth spending 20 minutes on the entity decision. The 유한책임회사 (LLC) is not the default choice for every foreign founder — and picking the wrong structure creates tax headaches you'll carry for years.
When an LLC Makes Sense vs. Sole Proprietorship or Branch Office
The Korean LLC (유한책임회사, governed by the Commercial Act (상법)) gives you personal liability protection and a separate legal entity. That matters if you're taking client contracts, hiring staff, or need investment credibility.
Individual business registration (개인사업자) is faster (sometimes same-day at the tax office), cheaper, and appropriate if you're freelancing or running a very small operation. You don't need court registration at all. The trade-off: you are personally liable for all business debts.
Branch office makes sense if a foreign parent company is expanding into Korea — but this is a different process entirely, involving notarized parent-company documents and foreign investment reporting.
If you're a solo consultant billing under ₩100M/year, the individual registration is probably the better move. If you need contracts, employees, or a structure that can support a D-10 investor visa application, the LLC is the right tool.
Visa and Tax Implications for Foreign LLC Owners
Owning a Korean LLC does not automatically give you a work visa. Your visa situation is separate from your business registration, and confusing the two is the most common mistake foreign founders make in their first month.
If you're on an E-7 (specific activities) or F-series visa, you may be able to run an LLC as a side activity — but check your specific visa conditions with the Ministry of Justice (법무부), as permitted activities vary by visa subtype and are subject to change. If your goal is to use the LLC to sponsor a D-10 investor visa, there are capital requirements involved (covered in the final section).
For tax: as a foreign LLC owner, you're looking at both corporate income tax on the company and personal income tax on any salary or dividends drawn. If you're a Korean tax resident (183+ days/year), you're taxed on global income. If not, only Korean-source income. These distinctions matter — get advice specific to your situation.
Pre-Registration: Documents and Setup You'll Need
The LLC registration process in Korea has a firm sequential dependency structure. You need a business address before the court will register you. You need the court registration number before most banks will open a business account. Understanding this chain before you start saves weeks.
Document Checklist
At minimum, prepare the following before your first court visit:
- Valid passport (original + certified Korean translation if not in Korean)
- Alien Registration Card (ARC) if you're a Korean resident — this dramatically simplifies everything
- Proof of Korean business address (lease agreement or office service contract)
- Articles of incorporation (정관) — must be notarized
- Seal registration (인감) or signature authentication
- Initial capital deposit certificate from a bank (자본금 납입증명서) — even ₩10M is sufficient for most registrations, but verify current minimums directly with your local court registry, as requirements can vary
If you're non-resident, you'll also need an apostille-authenticated copy of your passport from your home country. This alone can take 2–3 weeks if you're starting from scratch.
Choosing Your Business Name and Checking Availability
Your company name must include 유한책임회사 or an abbreviation. You can check existing registrations through the Supreme Court's (대법원) corporate registry system (인터넷등기소, iros.go.kr). The search is free and takes minutes.
Names that are identical to existing registrations in the same jurisdiction and industry are rejected. Names that imply government affiliation or use restricted terms (e.g., "Bank," "Insurance" without licensing) are also rejected.
Pick three candidates before you go. Courts don't hold names pending review — if yours gets rejected, you restart.
Bank Account Setup: The Chicken-and-Egg Problem
Most Korean banks will not open a business account until you have a business registration certificate (사업자등록증) from the National Tax Service (국세청). You can't get that certificate until you've completed court registration. And some courts ask for evidence of capital deposit before they'll process your incorporation.
The workaround: use a personal account (in the founder's name) as a temporary capital deposit account. Get the bank to issue a balance certificate (잔고증명서) showing the capital amount. This is accepted by most district courts as capital proof during initial registration. After you get your business registration number, you open the proper business account.
This sequence — personal account → court registration → tax registration → business account — is not explained anywhere on official websites. It's just what actually works.
The Registration Process: Step by Step
Here's the core of how to register an LLC in Korea, in the order you actually do it.
Step 1 — File Incorporation Papers at the District Court
The 유한책임회사 is registered at the District Court Registry Office (등기소) with jurisdiction over your business address. In Seoul, filings go through the registry division of the Seoul Central District Court (서울중앙지방법원). In other cities, find the local court registry (등기소) — locations are listed at iros.go.kr.
You'll submit: - Articles of incorporation (정관), notarized - Minutes of the founding meeting (설립총회 의사록) - List of members/managers - Capital deposit certificate - Court registration fee (등록면허세 + education surtax, calculated on capital amount)
Processing time from the registry office: typically 3–5 business days as of 2026, though this can vary by office workload. You'll receive a registration certificate (법인등기부등본).
Step 2 — Register with the Tax Office (국세청)
Within 20 days of court registration, file for business registration at your local tax office (세무서). Bring:
- Court registration certificate (법인등기부등본)
- Lease agreement for business address
- Passport + ARC
- Application form (사업자등록신청서)
According to the National Tax Service (국세청, nts.go.kr), a business registration certificate (사업자등록증) is typically issued within 2–3 business days in most cases; allow extra time during peak periods.
This certificate is what everyone — banks, clients, government agencies — will ask for. It's your operational proof of existence.
Step 3 — Register with the Local Labor Office (If Hiring Employees)
If you're hiring from day one, you'll also need to register with the National Health Insurance Service (국민건강보험공단) and notify the Korea Workers' Compensation and Welfare Service (근로복지공단) within 14 days of hiring your first employee.
Payroll tax obligations activate immediately upon employment. Don't backfill this — the penalty structure for late registration is not worth it.
What Most Guides Get Wrong About Korean LLC Costs
The honest answer to "how much does it cost?" is: government fees are cheap; professional help is where the money goes.
Hidden Fees Expat Accountants Won't Tell You
Court registration fees (등록면허세) are calculated based on registered capital. At ₩10M capital, according to publicly available rate schedules, you're looking at roughly ₩40,000–₩120,000 in government fees — but rates are updated annually, so verify current figures at iros.go.kr or Minwon24 before filing. Document notarization, certified translations, and apostilles are extra — budget ₩100,000–₩300,000 depending on your home country.
What accountants (세무사) charge: anywhere from ₩300,000 to ₩1,500,000 for "full service" LLC setup, based on widely reported industry estimates. That typically covers document preparation, court filing, and tax registration. It does not usually include ongoing monthly bookkeeping or VAT filing, which are separate contracts.
You can do this without a 세무사. It requires reading the court registry forms carefully (available in Korean) and making two in-person visits. If your Korean is limited, the Seoul Global Center (서울글로벌센터, global.seoul.go.kr) offers free consulting for foreign founders that can help you prepare documents correctly.
Real Timeline vs. "5-Day Registration" Claims
The "5 days" refers to court processing time only. Here's the actual elapsed-time breakdown for most foreigners:
| Stage | Typical Duration |
|---|---|
| Apostille + document prep (if non-resident) | 2–4 weeks |
| ARC issuance (if new to Korea) | 2–3 weeks |
| Court registration processing | 3–5 business days |
| Tax office registration | 2–3 business days |
| Business bank account opening | 1–4 weeks |
| Total elapsed time | 4–10 weeks |
If you already have an ARC and all documents ready, you can compress this significantly. But "already have everything ready" describes almost nobody starting from scratch.
Why Your LLC Might Be Rejected
Common rejection reasons at the court registry: - Business name conflict with an existing registration - Articles of incorporation contain prohibited clauses or are missing required fields - Capital deposit evidence doesn't match the articles (different amounts, different account holder name) - Non-resident documents not properly apostilled or translated
The tax office rejection rate is lower, but errors in the business category codes (업종코드) can create VAT registration problems later that are painful to unwind.
Post-Registration: Banking, Taxes, and Compliance
Opening a Business Bank Account With Your New Registration
With your 사업자등록증 in hand, you can now open a corporate bank account. Kookmin (KB국민은행), Shinhan (신한은행), and KEB Hana (KEB하나은행) all have foreign-language support desks in major cities. IBK Industrial Bank of Korea (IBK기업은행) is often recommended for small businesses and is generally foreigner-friendly.
Bring: business registration certificate, court registration certificate, your passport, and your ARC. Some banks will also ask for the actual articles of incorporation. Branch-level requirements can vary, so call ahead to confirm the document list before visiting.
For more detail on which banks will actually approve a foreign-owned LLC without excessive runaround, see How to open a Korean business bank account as a foreigner.
Monthly and Quarterly Tax Filing Obligations
Once registered, you have standing obligations as of 2026 :
- VAT (부가가치세): General taxpayers file twice yearly (returns due in January and July for the preceding half-year period); simplified taxpayers may file annually. Confirm your taxpayer classification at registration.
- Corporate income tax: Filed annually, due within 3 months of fiscal year end
- Withholding taxes: Due monthly if you're paying salaries
Missing these deadlines carries automatic penalties under the Framework Act on National Taxes (국세기본법). Set calendar reminders on day one.
For the full breakdown of deadlines and penalty structures, see Quarterly corporate tax filing deadlines and penalties.
Employment Registration If You Hire Staff
Four insurance registrations are required when hiring: national health insurance, national pension, employment insurance, and industrial accident compensation insurance. All four should be registered within 14 days of the first hire. The 4대보험 portal (4insure.or.kr) handles all four in one place, which is genuinely more efficient than it sounds.
Timeline and Costs: Real Numbers
Government Fees Breakdown
The figures below reflect publicly available schedules as of 2026; verify current rates before filing, as they are updated annually:
- Court registration (등록면허세 + education surtax): ~₩80,000–₩200,000 depending on capital
- Notarization of articles (공증): ~₩100,000–₩200,000
- Business registration at tax office: Free
- Certified translations (if required): ~₩30,000–₩80,000 per document
DIY total government cost: roughly ₩200,000–₩500,000.
Optional Professional Help Costs
Fee ranges below are based on widely reported industry estimates and may vary by provider and complexity:
- 세무사 (tax accountant) for setup only: ₩300,000–₩800,000
- Attorney for complex cases (non-resident, foreign investment reporting): ₩500,000–₩2,000,000+
- Monthly bookkeeping retainer (post-registration): ₩150,000–₩400,000/month
Realistic Total Timeline
If you arrive with your ARC already issued and documents in order: 2–3 weeks to full operational status.
If you're starting without ARC, documents need apostille, or you're non-resident: 6–10 weeks is realistic. Plan accordingly before making client commitments that depend on having a registered business entity.
Visa Sponsorship and Immigration: The D-10 Investor Visa
How LLC Registration Affects D-10 Visa Status
The D-10 visa (구직·창업 비자) has a startup track that allows foreign founders to reside in Korea while developing a business. Registering an LLC can support a D-10 application, but the LLC registration alone does not guarantee visa approval. Visa policy is administered by the Ministry of Justice (법무부) and eligibility conditions are subject to change — verify current requirements at the Hi Korea portal (hikorea.go.kr).
For more on eligibility and renewal, see D-10 investor visa eligibility and renewal conditions.
Capital Requirements and Proof of Investment
For foreign investment registration (외국인투자 등록) under the Foreign Investment Promotion Act (외국인투자 촉진법), the minimum qualifying investment is reported as USD 100,000 (approximately ₩130,000,000–₩140,000,000 at mid-2026 exchange rates) — however, this threshold and the KRW equivalent are subject to change. This is a separate requirement from the LLC's registered capital.
If your investment amount qualifies, register with KOTRA (대한무역투자진흥공사) and obtain a foreign investment registration certificate. This certificate strengthens visa applications and opens access to certain government support programs.
Renewal Conditions Tied to Business Continuity
D-10 visa renewals are not automatic. Immigration authorities assess whether the business is genuinely operational: active tax filings, business bank account activity, and evidence of actual business activity (contracts, client invoices, employee records). A registered-but-dormant LLC is not a strong renewal basis.
Keep your tax filings current and maintain documented business activity from the start.
The first time I helped a foreign team navigate this process — a French SaaS startup that came to me in 2018 with a court rejection already in hand — the issue wasn't paperwork. It was the sequence. They'd tried to open a business bank account before they had a 사업자등록증, got turned away, assumed something was broken, and stalled for six weeks. I've seen this same pattern repeat across dozens of registrations since. Once you understand that this is a chain — not a checklist — the process becomes manageable. That's what I've tried to capture here.
Frequently Asked Questions
Can I register a Korean LLC without a Korean resident address?
You need a business address registered with the court — this is non-negotiable. Your business address does not have to be your personal residence. Virtual office services and co-working spaces in Korea can provide a registered business address, and courts generally accept these if the provider can supply a proper lease or service contract. The catch: some banks are skeptical of virtual addresses when opening accounts, and some visa applications require a verifiable physical location. If you're using a virtual address, get the contract documentation in order before your court filing.
How much does it actually cost to register an LLC in Korea?
If you do it yourself, expect ₩200,000–₩500,000 in government fees and notarization costs (as of 2026 — verify current rates before filing). Add ₩300,000–₩800,000 if you hire a 세무사 for the setup. Ongoing costs (monthly bookkeeping, quarterly VAT filing) are separate — typically ₩150,000–₩400,000/month depending on transaction volume. The frequently advertised "₩100,000 LLC registration" figures refer only to the registry fee at minimal capital levels and omit notarization, translation, and professional fees. Budget for the full sequence, not just the court fee.
Do I need a Korean bank account before registering my LLC?
Not a business account — but you do need a Korean bank account (personal) to generate the capital deposit certificate the court requires. Most resident foreigners with an ARC can open a personal account at Kookmin (KB국민은행), Shinhan (신한은행), or KEB Hana (KEB하나은행) within a day or two. Non-resident foreigners without ARC have a harder time and may need to work through a Korean representative or a designated foreign bank branch. Once court registration and tax registration are complete, you use those certificates to open the actual corporate account.
Can my Korean spouse own the LLC instead if I'm not a permanent resident?
Legally yes — a Korean citizen can be the registered representative and majority member. This is a structurally valid approach and some foreign founders use it to simplify the registration process. However, the tax and legal implications are real: the Korean spouse becomes personally exposed to the company's obligations, income attribution for tax purposes becomes complicated, and this arrangement can complicate visa applications if you later want the company to sponsor your residency. If you go this route, get proper legal advice on the ownership structure and document the arrangement in the articles of incorporation from day one.
How long does Korean LLC registration actually take?
Court processing: 3–5 business days. Tax office registration: 2–3 business days. Those are the government steps. The actual elapsed time from "I've decided to register" to "I have a working business account" is typically 4–8 weeks for someone with their ARC, documents ready, and a business address lined up. Add 2–4 weeks if you need apostilled documents from abroad, are applying for an ARC simultaneously, or encounter a rejection requiring resubmission. The bottlenecks are document preparation and bank account approval — not government processing.
What to Do Next
Your immediate next step: check whether you already have the three prerequisites — a valid ARC, a Korean business address (or a virtual office contract), and a personal Korean bank account. If any of those are missing, that's your starting point, not the court filing.
Once you have registration in hand and a business account open, your compliance clock starts. VAT registration and the first quarterly filing will come sooner than you expect.
