Setting Up a Single-Member Corporation as a Foreigner in Korea: Feasibility and Real Requirements

A foreigner can absolutely form a one-person corporation in Korea where they serve as sole shareholder and representative director. Following amendments to the Commercial Act, both stock companies (jusik hoesa) and limited companies (yuhan hoesa) can be set up with a single promoter and a single director, and there is no step in the process that blocks foreigners simply because of nationality. That said, "is it possible" and "does it actually work in practice" are two different questions. Capital requirements, visa linkage, the remittance route, and the document formats demanded by the registry, tax office, and bank all interlock at the same time.

In practice, single-member corporations split into two tracks. First, a one-person corporation aimed at the D-8 investment visa (capital of at least KRW 100 million, foreign-invested company registration required). Second, simply incorporating without a visa attached (no capital threshold, but foreign exchange reporting, tax, and banking procedures still apply). The two differ on everything from capital threshold to remittance flow to the timing of the office lease. Starting under the assumption that "one person means it'll be simple" without grasping this distinction usually means hitting a wall at the bank account opening stage.

1. Is a Foreign One-Person Corporation Legally Possible?

The Legal Basis for a One-Promoter, One-Director Structure

The Commercial Act requires at least one promoter and at least one director (a single director is permitted if capital is below KRW 1 billion) for forming a stock company. In other words, there is no legal obstacle to one person being promoter and shareholder while also serving as director and representative director. There is also no provision in the Commercial Act that restricts qualification as a promoter or director on the basis of foreign nationality alone.

Here's the key point. Whether "a foreign one-person corporation is possible" is not a Commercial Act question — it's a question of immigration, foreign exchange, tax law, and banking practice. That's where things usually trip up.

Where Foreign Nationality Does Affect Things

Even though forming the corporation itself is allowed, foreign status becomes a variable at the following steps.

• Foreign Exchange Transactions Act: Remitting capital requires either a foreign investment notification or a non-resident capital transaction notification
• Immigration: If the foreigner needs to reside in Korea to operate the corporation, visa linkage such as D-8 becomes necessary
• Banking: Opening a corporate account in the name of a foreign representative requires extra paperwork and an in-person visit
• Tax: Withholding tax applies when dividends are paid to a foreign shareholder

You can form the entity, but whether you can actually run it after forming it is the real dividing line.

2. One-Person Stock Company vs. Limited Company — Which Fits?

Practical Differences Between the Two Forms

The form most foreigners choose is the stock company. But for a one-person structure, a limited company can sometimes be simpler. Here's a side-by-side comparison.

When the Limited Company Is the Right Fit

If there's no plan to bring in outside investors and the entity is meant to be a Korean subsidiary where the parent company holds 100% of equity intact, the limited company is the simpler choice. Conversely, if you plan to grow the business in Korea and anticipate future share issuance, share transfers, or employee stock options, the stock company is the right fit. One-person founders eyeing the D-8 visa almost always go with the stock company, because that's where the consulate review and foreign-invested company registration processes have the deepest track record.

3. Capital Requirements — KRW 100 Million vs. Below

Two Tracks for Capital

The Commercial Act sets no separate minimum capital for a stock company. A corporation with one share at KRW 100 (i.e., KRW 100 of capital) can technically be registered. However, for a foreigner setting up a one-person corporation to do business in Korea, in practice you'll fall into one of two brackets.

What KRW 100 Million in Capital Actually Means

For D-8 visa linkage, the foreigner must wire at least KRW 100 million in their own name and complete the foreign investment notification. It's not enough to simply "have" KRW 100 million sitting in an account. The flow has to clearly show a foreign-currency remittance from the home country into Korea, in the foreigner's own name. Loans taken out within Korea, money borrowed from a Korean resident, or KRW already inside Korea will not be recognized as foreign investment.

4. Can You Set Up a One-Person Corporation Without a Visa?

Possible Even While Residing Abroad

A foreigner can incorporate a one-person company even without ever entering Korea. Articles of incorporation, promoter meeting minutes, and acceptance of office letters are notarized with the foreigner's personal signature, then certified through home-country notarization plus apostille (or authentication at the Korean consulate in that country) before being sent to Korea.

That said, this route has two big constraints.

1. Corporate seal registration and the registration filing must take place inside Korea. If the principal can't come, a power of attorney is required.
2. Opening the corporate bank account is something nearly every commercial bank in Korea requires the foreign representative director to handle in person, on Korean soil. It cannot be done by email or mail.

In short, the corporation can be formed from afar, but starting operations ultimately requires a trip to Korea.

Limits of a Corporation Set Up Without a Visa

If you set up a one-person corporation with capital below the D-8 threshold (KRW 100 million), here is what you get:

• Corporate registration: yes; business registration: also possible
• Foreign-invested company registration: not possible → no D-8 visa eligibility
• If the foreigner wants to live in Korea and actively run the business, a separate visa (e.g., F-series, E-7) is required
• The result tends to be something close to a "paper company"

The first thing to look at is "after forming this corporation, will the principal actually come to Korea and work here?" If yes, capital must be set at KRW 100 million or higher to keep the D-8 line open.

5. Step-by-Step Incorporation Flow

Standard Sequence for a One-Person Corporation

Where the Process Tends to Break Down

The table looks smooth on paper, but breakdowns tend to happen at steps 3↔4, 7↔8, and 9↔10. After capital is wired, the deposit certificate comes back with the wrong code. The lease isn't in the foreigner's name when business registration is filed. The bank's head office adds an extra review at account opening because "the sole representative is foreign." These are the usual chokepoints, so build slack into the schedule.

6. Required Documents and Home-Country Preparations

Documents to Prepare in Korea

• Articles of incorporation, promoter resolution, acceptance of office for director and representative director, signature notarization in lieu of seal certificate
• Lease agreement (or letter of consent) proving the head office address
• Capital deposit certificate (for incorporation by promotion)
• Copy of the foreign investment notification (if applicable)

Documents to Prepare in the Home Country

If the foreigner is in their home country, the following must be notarized in the home country, then either apostilled or authenticated by the Korean consulate, and sent to Korea.

Passport copy (bio page)
Residence or address certificate (in English)
Notarized signature certificate
Apostille or consular authentication (apostille for Hague Convention countries; consular authentication otherwise)
Home-country ID or driver's license copy (for bank KYC)
Overseas occupation/income evidence (to explain the source of capital)
Home-country bank statements covering 6–12 months (to explain fund flow)
Power of attorney for an in-Korea representative (if the principal is not visiting)

Even with plenty of documents, a weak source-of-funds explanation triggers a request for supplementation at the foreign investment registration stage. Money in the account isn't enough — without a clear flow narrative, things can unravel quickly.

7. Real-World Issues for the Sole Representative

Self-Dealing and Board Resolutions Get Stricter Precisely Because There's One Person

In a one-person corporation, the shareholder, director, and representative director are all the same individual. Within this structure, when the foreign representative transacts with themselves or with their home-country company (e.g., borrowing funds from the parent or providing services to the parent), the self-dealing rules and transfer pricing rules kick in simultaneously.

• Commercial Act Article 398, self-dealing → board approval (in a one-person corporation, replaced by shareholder meeting minutes)
• International Tax Adjustment Act → transactions with the parent or overseas affiliates are subject to arm's-length verification

The paperwork side moves quickly because there's only one person, but actual review scrutinizes "whether this transaction is reasonable" even more closely. If the explanation is thin, the gap shows up at the tax audit stage.

When the Sole Representative Is Not in Korea

It's possible to structure the company so the one-person representative stays in the home country while only employees are placed in Korea. But the following must be sorted out in advance.

• A Korean service-of-process address (a notice-receipt address separate from the office or registered address)
• A means of personal authentication for issuing tax invoices and obtaining the e-tax invoice certificate
• A delivery channel for the security card / OTP used for corporate internet banking

It's legal for the representative to be based outside Korea, but the real burden is that Korean administrative systems were not designed assuming an absent foreign sole representative.

When Visa and Residency Are Tied Together

Once a foreigner becomes the sole representative under a D-8 visa, that corporation must continuously maintain its foreign-invested company status for the visa to be renewable. Withdrawing capital arbitrarily, or transferring the principal's equity to a non-foreign-investor, immediately rocks the visa qualification. Before worrying about whether things will be approved, understand that corporate operations and visa qualification are bound together.

8. Common Mistakes

① Thinking You Just Need to "Hit" the KRW 100 Million Number

The remittance flow must run cleanly from the foreigner personally → the Korean corporate account (or capital deposit account). Routing the funds through a Korean resident first and then into the corporation is not recognized as foreign investment.

② Listing Only Yourself in the Articles, with the Chair and Auditor Sections Blank

Even in a one-person company under the Commercial Act, the articles must specify how a chair is elected and the procedures replacing the shareholder meeting, otherwise decision-making cannot be enforced if a dispute arises. Drafting articles loosely on the assumption that "there's no one to argue with" creates problems down the line at sale, fundraising, or inheritance stages.

③ Signing the Lease at a Residential Address

If you list a family residence or a short-term rental as the head office, the foreign-invested company registration will come back with a "substance unverified" supplementation request. The lease must be at a space recognized as office use (shared offices included, though "non-resident" formats are limited).

④ Registering the Business Scope Too Narrowly

One-person corporations often start with a narrow scope and then forget to file additions when actual revenue starts coming from a different category. The scope should be registered from the outset based on a one- to two-year forward plan.

⑤ "Just Set It Up Without a Visa" and Then Run It on a Short-Term Stay

If the principal personally runs a one-person corporation set up without a visa while in Korea on a short-term visa (B-2/C-3), this can constitute activity outside the permitted status. Staying in Korea to operate a business requires a separate qualification such as D-8.

9. Frequently Asked Questions (FAQ)

Q1. Can a foreigner be sole shareholder and at the same time sole director and representative director?

Yes. A stock company with capital below KRW 1 billion needs only one director, and incorporation is recognized even with a single promoter. Foreign nationality alone does not bar director qualification. That said, corporate seal registration and the registration filing require either the principal or an authorized representative to handle the in-Korea procedure.

Q2. If I can't reach KRW 100 million in capital, is the D-8 visa absolutely impossible?

In principle, the minimum recognized as foreign investment is KRW 100 million, and anything below this won't be registered as a foreign-invested company, so D-8 eligibility doesn't open up. Splitting the contribution (e.g., KRW 50 million from you + KRW 50 million from a foreign business partner) to reach the KRW 100 million foreign investment total is workable, but this conflicts with the definition of a one-person corporation (single shareholder) — at that point, you have a two-person, not a one-person, structure.

Q3. As a one-person corporation, can we skip having a statutory auditor?

A stock company with capital below KRW 1 billion may waive the appointment of a statutory auditor (Commercial Act Article 409). A one-person limited company has no auditor requirement to begin with. The basis for the auditor waiver must be clearly written into the articles and reflected in the registration.

Q4. Can I set up a one-person corporation without ever visiting Korea?

Up through the incorporation itself, yes. With a combination of home-country notarization + apostille + power of attorney, you can handle registration and business registration. However, opening the corporate bank account and applying for the D-8 visa require the foreigner to appear in person in Korea or at the Korean consulate in their home country. The realistic flow is "incorporation can be remote, but starting operations is in person."

Q5. Can foreign or Korean business partners be added to a one-person corporation later?

Yes. Shareholders can be added through a new share issuance or transfer of existing shares. However, if a one-person corporation that needs to retain foreign-invested company status sells partial equity to a Korean, this triggers a change in foreign investment ratio filing with the authorized bank. If the foreign investment ratio drops below a certain threshold, the foreign-invested company status is lost, and the D-8 visa qualification gets rocked along with it.

10. Consultation

For a foreign one-person corporation, the dividing line is less "possible vs. impossible" and more how the capital flow, visa, registration, and tax all line up in a single sequence. A single remittance code on the KRW 100 million wire, a single line on the head-office lease, a single clause in the articles about chair election — any of these can decide whether the next step clears.
