Registering a Business in Korea as a Foreigner

The first distinction a foreigner starting a business in Korea must make is between two questions that sound identical and are not: can I register a business, and does my current visa allow me to actually run it?

Two authorities, and neither validates the other

A business registration certificate is a tax document, not permission

1 · Confirm the residence status permits the activityD-8-1 from ₩100M with 10% of shares; D-9 from ₩300M for a sole trader

2 · Remit the capital and file the foreign-investment report

3 · Register the business at the tax officeWithin 20 days of commencing

4 · Open the corporate accountWhere the AML review actually happens

The National Tax Service’s business registration is a tax procedure — it registers you as a business operator. Your status of stay is an immigration matter — it defines which income-generating activities you may lawfully perform in Korea. A freshly printed business registration certificate does not legalize business activity your visa does not permit.

Get the order right and everything downstream gets easier: confirm the immigration side against your actual business plan first, then choose the structure (sole proprietor vs corporation), then move through registration, banking, tax, and financing. Invert that order and problems compound.

Which visas allow business activity — and which need permission first

F-5 (permanent residency) carries the fewest restrictions on business activity. F-6 (marriage-based) is also generally broad on employment and income-generating activity. F-2 and F-4 can support business activity in defined circumstances, but the permitted scope depends on the specific sub-status — verify, don’t assume.

The work-visa group is different in kind. E-7 authorizes stay on the basis of an approved occupation and an employment relationship; starting your own business on the side can fall outside your permitted activity, so check status-change or extra-activity permission (체류자격 외 활동) before acting, not after.

D-2 students are clearer still: the Ministry of Justice restricts student employment and income-generating activity to approved part-time work and separately permitted activities. Registering a business and running an online shop or a restaurant is not the same category as an approved part-time job. D-10 is a job-seeking status with defined startup-preparation allowances — not a general business visa.

So checkpoint number one is not the tax office. It is whether your current status of stay permits the actual management activity you are planning.

D-8 is not “make a corporation, get a visa”

For a foreigner investing in a Korean corporation and managing it directly, the flagship status is D-8. In the standard D-8-1 structure, the baseline foreign-direct-investment requirement is an investment of at least ₩100,000,000 with ownership of at least 10% of voting shares — Invest KOREA’s guidance describes the D-8 route for foreigners bringing in ₩100M+ from abroad to establish and run a Korean corporation.

The key subtlety: ₩100M does not mean “have ₩100M sitting in a Korean account.” The money has to trace through the FDI process — foreign investment notification, remittance or importation of the funds from abroad, incorporation, business registration, and foreign-invested-company registration. D-8 screening can ask for remittance confirmations, foreign-currency purchase certificates, corporate registry extracts, the business registration certificate, records of how the capital was used, and the office lease. Moving ₩100M of money you already held in Korea into a corporate account does not, by itself, complete the FDI requirement.

D-9 sole proprietorships are a ₩300M story, not ₩100M

Here is the error most foreign-startup articles make. The thresholds differ by structure:

Structure	Representative investment threshold
D-8-1 — invest in a Korean corporation	Foreign investment ≥ ₩100M + in principle ≥ 10% voting shares
D-9 — independent foreign-owned sole proprietorship	Foreign investment ≥ ₩300M
D-8-3 — joint sole proprietorship with a Korean partner	Separate joint-investment and co-representative requirements

Invest KOREA’s guidance is explicit that a foreigner operating a private business that is not a joint venture with a domestic business falls under D-9 when the investment is ₩300M or more.

And the flip side matters just as much: these amounts are visa/FDI thresholds, not a general minimum capital for foreign-owned businesses. An F-5 or F-6 holder opening a small business has no reason to apply the D-8 or D-9 figures to themselves — they need no investment visa.

Sole proprietor vs corporation: liability and funding split before tax does

For a small service business or one with modest early revenue, a sole proprietorship (개인사업자) is simple — to open, to account for, and to close. Profit and loss flow directly to you, and so does liability: the business’s obligations are personally yours.

A corporation (법인) is a separate legal person. Shareholders’ liability is in principle limited to their contribution, company assets separate from the CEO’s personal assets, and the structure cleanly supports investment, share transfers, corporate-name financing, and dealings with overseas affiliates. Invest KOREA frames the trade the same way: sole proprietorships are procedurally simple but fundraising-constrained; corporations are more complex to establish but stronger on financing and the separation of ownership and management.

Tax differs too — sole-proprietor profit runs through personal comprehensive income tax, corporate profit through corporate tax — but resist the folk rule “above revenue X, a corporation always saves tax.” Taking corporate profit out as salary or dividends triggers a second, personal-level tax; using corporate money personally creates 가지급금 (provisional payments) and deemed-bonus problems. The conversion decision is really three joint questions: how much profit will stay retained in the company, how large will future investment and borrowing be, and how much must you personally extract as income?

Registration is an administrative step — not a financial identity

The NTS requires business registration per place of business within 20 days of starting (application before starting is allowed). Sole proprietors file the application with the lease agreement and any required licenses, plus — for foreigners — an ARC or passport copy. Corporations file incorporation plus business-registration forms, the corporate-name lease, and the shareholder/investor schedule.

But a registration certificate does not make a bank treat you as an established business. The tax office and the bank are answering different questions — which brings us to the actual first financial hurdle.

The real banking hurdle is AML and purpose verification

A new foreign-owned business’s first financial problem is usually not the loan. It is the account.

Under KYC and anti-money-laundering obligations, banks can verify the real representative, beneficial owners, business substance, transaction purpose, expected volumes, and source of funds. A foreign CEO, or a company expecting frequent overseas transfers, should expect more verification, not less. Walking in with only the registration certificate and corporate seal certificate and expecting a full-function account is the standard rookie error — the bank may probe the actual premises, the shareholder and beneficial-ownership structure, the business purpose, projected revenue, and contracts. Newly formed companies with zero revenue, shared-office addresses with vague activity, or repeated large inbound foreign transfers get the most scrutiny.

The same limited-account system that applies to personal accounts applies here, and the lifting logic is identical: substance, not time. “Use it a few months and it unlocks” is not how it works. What works is evidence of a real business — tax invoices, contracts, settlement inflows, VAT filings, the office lease, payroll records. A pre-revenue company substitutes supply contracts, purchase orders, licenses, the lease, and capital-injection records. If the bank asks for a site visit, the point is not hastily mounting a sign — the premises need real workspace, equipment, inventory, or staff consistent with the registered business. Manufacturing fake contracts to escape the limit is the one move worse than staying limited.

A business loan is not a right that comes with registration

The registration certificate is an operating document, not a credit file. What a lender needs is a repayment source.

For sole proprietors: the owner’s KCB/NICE credit file, business tenure, declared income, VAT-reported and card revenue, existing debt, and tax compliance. For corporations: financial statements, revenue, operating cash flow, leverage, tax payment history, and collateral. A new corporation has almost no credit history of its own, so the CEO’s personal credit and guarantee weigh heavily — which is one more reason to build your personal Korean credit base first.

For foreign CEOs one factor is added: stay stability. An imminent visa expiry, or an unclear basis for continuing to run the business in Korea, gives the lender a management-continuity question to resolve — though, as with personal loans, no industry-wide “months remaining” cutoff exists. What underwriting ultimately wants is a structure in which the business continues and the cash that repays the loan is generated in Korea.

Policy funds and guarantee institutions don’t decide on “foreign CEO” alone

Whether a foreign-owned business can use regional credit-guarantee foundations or small-business agency (소상공인시장진흥공단) programs depends on each program’s own eligibility and guarantee criteria. Being registered does not qualify you for every program; being foreign does not disqualify you from all of them. Conditions vary by location, industry, tenure, headcount, revenue, arrears, and the CEO’s residence status — and program names and limits change, which is why this guide deliberately does not hard-code any. Judge against the institution’s current notice at the time you apply.

Leasing preserves a new company’s cash — but not the CEO’s exposure

Foreign CEOs commonly lease vehicles or equipment in the corporate name right after incorporation, and the core benefit is real: tens of millions of won stay liquid as working capital instead of converting into assets on day one.

But a thin-credit new corporation should expect the lessor to want a larger deposit, CEO credit support, or extra documentation — a corporate contract does not sever the financing from the CEO’s personal credit. And for cars, skip the “lease payments are fully deductible” folklore: company-vehicle costs face depreciation-equivalent caps, business-use ratios, and business-use insurance requirements, all covered in our car lease guide. Classify business leasing correctly: a financing tool that preserves early cash while using the asset — not a tax product.

Separate FDI money, company money, and your money from day one

If you built the company on notified foreign investment, the post-founding flows deserve stricter discipline than a domestic founder needs. When notified investment capital, operating revenue, and the CEO’s living expenses mix in one account, explaining the capital’s origin and the accounting later becomes genuinely difficult.

Every payment from company to CEO needs a defined character — salary, dividend, expense reimbursement, or loan. Every payment from CEO to company likewise — additional capital, temporary advance (가수금), or loan. And when a foreign-invested company later repatriates dividends or recovers its investment, the original FDI notification and remittance records come back into play. Separating the corporate and personal accounts from the start is not bookkeeping tidiness; it is building the base file that every future bank, tax, and FX review will read.

As the business grows, the reasons to incorporate change

Early on, a sole proprietorship’s low overhead wins. As staff grow, larger counterparties sign, outside investment arrives, or borrowing scales, the weight shifts to liability separation and funding capacity — at which point conversion to a corporation is a financial restructuring, not a tax trick.

A few stage-specific cautions:

• Long-term settlers should design visa and business together: a D-8 operator building business results and residence history toward long-term status is running a different financial structure than an F-6 holder co-running a business with a Korean spouse.
• Do not borrow a spouse’s credit by adding them as a nominal co-representative or co-proprietor. Co-proprietors take on real income, tax, and debt consequences in proportion to their stake. Keep family relationships and business contracts distinct.
• Students and short-term residents should be the most conservative of all: being able to generate income and being permitted to run a business are different questions. Confirm the lawful scope first, manage the basics — account, cards, remittance costs — inside it, and expand into business finance, property, leasing, and loans only after reaching a long-term settlement stage.

What Korean financial institutions demand from a foreign-owned business is not complicated: who actually runs it, where the money came from, what business generates how much cash, and whether that cash can service the debt. The visa, the registration certificate, the corporate registry, the bank account, the tax filings, and the loan look like independent administrative events — but in a real credit review they are read as one continuous record. Keeping that record unbroken from day one is the whole strategy.

Which legal form to register in the first place — the reach of liability, the second layer of tax on money you take out, and the visa route attached to each — is compared in sole proprietor versus corporation.
