Why Many Foreign Companies in Korea Still Maintain a Local Korean Bank Account

A one-minute visual summary of this article.

Global Banking Platforms Are Often the Preferred Choice

Many multinational companies prefer to use the same banking platform across all jurisdictions in which they operate.

Global treasury teams often want to maintain centralized visibility and control over cash management, payment approvals, and internal control procedures. For this reason, global banking networks such as Bank of America, J.P. Morgan, HSBC and Citi are frequently used for Korean subsidiaries and branch offices.

From a treasury and governance perspective, this approach makes perfect sense. It allows payment approvals to be monitored and controlled by the headquarters treasury team while maintaining consistency with global policies.

However, practical challenges often arise when foreign companies attempt to operate in Korea using only foreign banks.

Understanding the Limitation

Unlike Korean domestic banks, many foreign banks in Korea operate through Seoul branches rather than full local banking entities.

As a result, certain banking services commonly available through Korean banks may not be available or may involve additional administrative procedures.

Citibank Korea is a notable exception because it acquired KorAm Bank and operates in a manner largely comparable to Korean domestic banks.

For most other foreign banks operating through Seoul branches, companies may encounter several practical limitations.

Practical Challenges Frequently Encountered

1. No Automatic Debit for Social Insurance Contributions

In many cases, companies cannot register automatic monthly withdrawals for the four major social insurance programs.

As a result, payroll administrators must manually process payments every month, increasing administrative effort and the risk of missed payments.

2. Tax Payments Cannot Be Processed Seamlessly Through Korean Tax Portals

Companies using foreign bank accounts may find it difficult to retrieve tax payment information and settle taxes directly through Korean tax portals using their bank accounts.

This often results in additional administrative work during monthly and annual tax filing periods.

3. Receiving Tax Refunds Can Be Surprisingly Complicated

One of the most inconvenient issues arises when the company becomes entitled to a Korean tax refund.

In certain cases, the National Tax Service may not be able to transfer the refund directly to a foreign-bank account.

Instead, the company may need to:

  • Receive the refund notice by mail;
  • Gather corporate documents;
  • Visit a local post office;
  • Collect the refund in cash; and
  • Remit the cash proceeds back into the company’s bank account.

While the process is manageable, it creates unnecessary administrative burden and consumes valuable management time.

4. Digital Certificate Procedures Can Be More Complicated

Many Korean tax, social insurance and government portals still require digital certificates for access and filing purposes.

The process for obtaining and managing these certificates is generally more straightforward when the company maintains an account with a Korean local bank.

Companies relying exclusively on foreign bank accounts may face additional procedures and administrative complexity.

The Hidden Cost Is Not the Bank Fee

When selecting a banking partner, foreign companies often focus on banking fees, cash visibility, foreign exchange services, and treasury controls.

However, in practice, the hidden cost is frequently the additional administrative effort required to deal with local compliance procedures.

These costs are not always visible during the initial setup phase but can become significant over time.

A Practical Solution

Based on our experience, many foreign companies achieve the best balance by adopting a dual-bank approach.

Under this arrangement:

  • The primary banking relationship remains with the group’s preferred global bank;
  • Headquarters treasury teams continue to utilize existing approval and control processes; and
  • A secondary account is maintained with a local Korean bank to handle domestic administrative matters.

The local account can be used for:

  • Social insurance payments;
  • Tax payments;
  • Tax refunds;
  • Digital certificate issuance and maintenance; and
  • Other Korea-specific compliance requirements.

This approach often reduces administrative burden while maintaining the benefits of centralized treasury control.

Our Recommendation

When establishing a Korean subsidiary or branch, companies should evaluate not only treasury requirements but also the practical administrative aspects of operating in Korea.

Where permitted by headquarters policies and internal systems, we generally recommend maintaining both:

A global bank account for treasury management and reporting; and

A local Korean bank account for administrative and compliance purposes.

In our experience, this combination provides the most efficient operating model for many foreign companies doing business in Korea.
