A foreign company opens its Korean corporate bank account only after the entity legally exists. The investment capital lands first in a temporary account at a foreign exchange bank, which issues the payment evidence court registration requires. The operating account opens once the commercial registry and the district tax office have issued their certificates, and the bank’s own review follows with real discretion.
This is the step foreign companies underestimate. Incorporation is procedural, as set out in the guide to how to start a business in South Korea. The bank is the one counterparty that can say no, and it says it more freely than any registry clerk.
What Is the Real Sequence for a Korean Corporate Bank Account?
Banking appears twice here, and confusing the two accounts is the most common planning error:
- Foreign investment notification, filed before any money moves at KOTRA, a KOTRA trade centre abroad, or a designated bank branch in Korea, and issued on the spot. That filing chooses the bank: the foreign-invested company registration at step 5 goes back to whichever institution took it (KOTRA guide 25-007, 2025).
- Temporary account at a foreign exchange bank, a non-resident foreign currency account or a temporary number that receives the wire.
- Capital remittance. The remitter name has to match the notification, the purpose has to read as company establishment or investment funds, and KOTRA’s slip template puts the company being established on the beneficiary line, though it does not yet legally exist. Hana’s template names the investor there, so settle that line with the branch first.
- Conversion and the payment evidence. The money converts into won and the bank issues the document the registry needs.
- Court registration, then the business registration certificate from the district tax office, then foreign-invested company registration, due within 60 days of full payment of the investment (KOTRA guide 25-007, 2025). That certificate is what the D-8 investor visa runs on, and what makes later dividend remittance routine.
- The operating account, and the paid-in capital moves across.
Which Payment Certificate Does the Registry Need: Custodian or Balance?
For a stock company, Article 318(1) of the Commercial Act requires a certificate from the custodian of the payment, the 납입금보관증명서. Article 318(3) carves out a lighter route: where capital is under KRW 1 billion and the promoters incorporate under Article 295(1), a bank balance certificate, the 잔고증명서, may be substituted (Commercial Act Article 318, law.go.kr, 2026, and KOTRA guide 25-007, 2025, which records the same substitution).
For the custodian certificate the bank holds the subscription money and certifies that custody to the court, and generally wants notarised copies of the articles of incorporation, the inaugural or promoters’ meeting minutes, the board minutes, and the share subscription certificate first (KOTRA guide 25-007, 2025), so confirm the list with the branch in advance. The balance certificate issues on application against the account balance. A team that assumes the custodian route buys a product a sub-KRW 1 billion promoter incorporation does not need.
Article 318 sits in the stock company chapter, so this is jusik hoesa machinery. The limited company chapter has its own rules: Article 548 makes the directors collect contributions in full, Article 549(1) sets registration within two weeks of that payment, and the sub-KRW 1 billion relief from notarising the articles covers a yuhan hoesa too (Commercial Act Articles 548 and 549; KOTRA guide 25-007, 2025). Settle the form with yuhan hoesa vs jusik hoesa, then have a Korean judicial scrivener confirm the payment evidence it needs.
Temporary Capital Account or Operating Account: Which Does What?
The temporary account proves the capital arrived: it holds the subscription money, produces the document the registry needs, and does nothing else. The operating account belongs to the registered company, carries its business registration number, and does everything else.
The paid-in capital sits at the bank meanwhile, and becomes transferable to the company’s own account only once incorporation registration and business registration are both complete. The transfer then needs the certified copy of the corporate register, the seal and its impression certificate, the business registration certificate, and the director’s original identification (KOTRA 25-007, 2025). Until then the entity has money and no way to spend it, so fund the deposits from the parent.
What Documents Do Korean Banks Ask For to Open a Corporate Account?
More than the registry did. KB Kookmin publishes its own corporate account list: the business registration certificate, the full corporate registration record, the corporate seal with its impression certificate, evidence of the account’s purpose, shareholder records, identification for whoever attends, and delegation papers for an agent (KB Kookmin, corporate account guide, 24 November 2025). Two of those carry a clock: KB wants the corporate registration record and the seal impression certificate issued within the past three months, so documents ordered at incorporation expire before a Korea trip booked four months later. The purpose evidence, a lease and tax invoices, is the same proof that lifts the limits below. On the seals, the 법인인감 is registered with the court at incorporation and the bank registers a separate seal for account operation, and whoever holds either binds the company.
Ownership catches people, because banks must identify the beneficial owner behind a corporate customer. The first test is a natural person holding at least 25 percent of the voting shares, with fallbacks to the largest shareholder, control of the officers, or de facto control (Enforcement Decree of the Specified Financial Transaction Information Act, Article 10-5). A subsidiary held through two holding companies needs a chart running to named individuals, and documents from outside the Hague Apostille Convention need consular legalization on a slower clock (HCCH status table, 2026).
Why Do Korean Banks Refuse or Delay Foreign-Owned Companies?
Because refusing costs the branch nothing and approving a bad file costs it a great deal. Article 5-2(4) of the Specified Financial Transaction Information Act requires refusal. Where a customer will not supply the information customer verification requires, the bank must refuse the transaction, account opening included, and terminate an existing relationship. Article 20 backs that with fines of up to KRW 30 million for a due diligence failure, and KRW 100 million where enhanced due diligence was required.
The refusal patterns are specific. An ownership chart that stops at a holding company. An address that is plainly a virtual office. A business description that differs from the articles of incorporation. Capital flows nobody can explain in a sentence. Most banks also expect the representative director in person. The difference between an address-only service and a shared office with an assigned unit, and which of them survives the tax office check, is worked through in the guide to business address options in Korea.
Ask the branch to state the gap in writing, because a named document is solvable and a shrug is not. Take the file to the corporate banking or foreign exchange desk, then to a second branch of the same bank before a second bank.
Why Does a New Korean Corporate Bank Account Barely Work in Week One?
Because new accounts open with hard transaction ceilings. Where a customer cannot document the account’s purpose at opening, the bank opens it as a limit-restricted account, a control aimed at borrowed-name accounts. The Financial Services Commission announced on 30 April 2024 that from 2 May 2024 the daily limits rose to KRW 1 million for electronic banking, KRW 1 million at an ATM, and KRW 3 million at the counter, with Nonghyup, Hana and Busan Bank applying them from 10 May (FSC, 30 April 2024). They apply across the commercial banks, so switching between them buys no higher limit, and lift on the same purpose evidence KB asks for at opening. Plan the first payroll around that.
Running the account remotely has its own gate. Corporate internet banking runs on a corporate digital certificate the company issues to itself using credentials collected at the branch counter, and nobody moves money from a screen until that is done. Give a resident finance manager delegated transfer authority when the account opens.
Which Bank Do You Open With, and in What Order?
The bank is effectively chosen at the notification step, because the foreign-invested company registration has to go back to whichever institution took the notification (KOTRA guide 25-007, 2025). Make that one decision deliberately, before any money moves: one large Korean commercial bank, at a branch that has handled foreign-invested company files, with a second relationship left for later.
Three of the big four publish their own material for this file. KB Kookmin publishes the corporate account document list cited above (kbthink, 24 November 2025). Hana’s business support centre publishes the foreign investment procedure flow with its remittance fields (biz.kebhana.com, 2026). Woori publishes a five-step new share acquisition procedure ending in foreign-invested company registration (spot.wooribank.com, 2026). That is published onboarding material: three banks that see the file often enough to document it.
Then respect the order, because the restriction on further accounts is cross-bank. KB Kookmin tells corporate customers that adding another account within 20 business days may be difficult (KB Kookmin, 24 November 2025), and the Korea Federation of Banks says on its consumer portal that banks restrict a new demand deposit account where the customer has an account opening on record in the past 20 business days (KFB consumer portal, 2026). Two qualifications: it bites only on demand deposit accounts, leaving term deposits outside it, and the Financial Supervisory Service introduced it in 2010, since 2021 running as self-regulation applied unevenly branch to branch (대한경제, 25 July 2023). One counter will wave it away and the next will enforce it, so carry purpose documentation to a second appointment.
Citibank Korea decided on 22 October 2021 to shut its consumer banking business in phases (KED Global, 2021), and now positions itself for corporate and institutional clients (Citi Korea, 2026), which fits a substantial relationship more than a three-person subsidiary’s first account.

Frequently Asked Questions
Can a foreign company open a Korean corporate bank account with no resident director? Banks apply their own standard, and a file with no Korean-resident officer or local staff draws heavier scrutiny under customer due diligence rules and reads to a branch as an empty vehicle. Fix it at entity design. The fix is a resident co-representative, or a resident finance manager with defined authority, in place before the appointment.
How long does opening a corporate bank account in Korea take? Bank review begins only after incorporation and business registration are complete. No Korean bank or regulator publishes a turnaround figure. A complete file is generally opened at the branch visit, while an incomplete one or a complex ownership chain goes to head office compliance and returns on the bank’s clock. The week one limits then constrain spending either way.
Can the representative director open the account remotely or by power of attorney? Assume in-person attendance. Most Korean banks expect the representative director at the branch, and reliance on a power of attorney needs the branch’s advance agreement. KB Kookmin’s published list includes delegation papers for an agent, so the route exists. Confirm it before booking flights.
Why is the new account capped at such a low daily transfer? Korean banks open a new account with limits where its transaction purpose is undocumented at opening, a control against borrowed-name fraud. The Financial Services Commission set them from 2 May 2024: KRW 1 million a day for electronic banking, KRW 1 million at an ATM, and KRW 3 million at the counter. They lift on evidence of a lease and tax invoices.
Getting the Banking Step in Sequence
Companies that run into trouble scheduled the account last, and it gates payroll, rent, and every supplier payment. File the notification at the institution you intend to bank with, confirm which payment certificate your entity form needs, and book the Korea trip around the branch visit. Joon K Lee helps international companies plan that sequence, with Inquivix delivering the Korea market entry and digital growth work once the entity is banked.
