1. Foreign Exchange Transactions Act | Basic Concept and Purpose
The Foreign Exchange Transactions Act is a statute that sets the standards for transactions in foreign currency, or in means of payment circulated abroad, between Korea and foreign countries in connection with trade, overseas travel, study abroad, overseas investment, and the like.
This law aims to promote a balanced balance of payments and a stable currency value, and to facilitate external transactions.
The Foreign Exchange Transactions Act applies broadly to the following three areas.
- Transactions in foreign exchange within Korea
- Transactions in foreign exchange between Korea and abroad
- Cases where a resident of Korea engages in foreign exchange transactions abroad
In short, it applies broadly not only to import and export companies but to all external transactions involving foreign exchange, including overseas direct investment, overseas real estate acquisition, overseas remittance, and set-off transactions.
Major Types of Illegal Foreign Exchange Transactions
- Carrying foreign currency, checks, or other means of payment out of or into the country without declaring them to customs
- Sending foreign currency out of the country by disguising, on paper only, the payment of import proceeds without any actual import of goods
- Intentionally underreporting the export price and then recovering and concealing the actual difference locally overseas
- Concealing export proceeds overseas or using them locally instead of bringing them back to Korea
- Carrying criminal funds, such as proceeds from smuggling sales, out of the country
- Carrying funds out of the country to raise criminal funds through smuggling and the like.
2. Foreign Exchange Transactions Act | Foreign Exchange Procedures and Reporting Obligations
Under the Foreign Exchange Transactions Act, export proceeds may be received freely, but depending on the method of receipt, the foreign exchange transaction must be reported to the Governor of the Bank of Korea.
If the amount for which the reporting obligation is violated exceeds the amount set below within the range of 500 million won or more, the violator may face imprisonment for up to 1 year or a fine of up to 100 million won.
An administrative fine of up to 100 million won may also be imposed.
The foreign exchange, securities, real estate, and the like obtained through this are confiscated as a matter of course, and where they cannot be confiscated, an equivalent value is collected.
Mandatory Requirements for Import and Export Foreign Exchange Transactions
1) Set-off between claims and obligations
If a company wishes to settle its export proceeds by setting them off against import payments, claim (damages) amounts, various fees, and the like that it already owes, rather than receiving the proceeds directly in cash, it must report this in advance to the head of the foreign exchange bank.
When a multinational company sets off the claims and obligations of multiple transactions on a lump-sum basis or carries out complex set-offs among multiple transaction parties, it must separately report this to the Governor of the Bank of Korea, and the statutory minimum retention period for set-off-related supporting documents is 5 years.
2) Long-term settlement (settlement beyond the deadline)
In principle, export proceeds must be settled within a set period before or after the goods are shipped, but a reporting obligation arises when proceeds above a certain amount go unsettled for a long time.
Specifically, for export proceeds exceeding USD 100,000 per contract, a company that wishes to receive payment more than 1 year before the goods are shipped must report this in advance to the Governor of the Bank of Korea.
3) Payment or receipt of proceeds through a third party
Prior reporting is also required when a third party who is not a party to the import or export transaction pays or receives the proceeds on its behalf.
A typical example is where a domestic importer pays a foreign counterparty not directly but through a third domestic counterparty, or, conversely, where another domestic or foreign company pays the export proceeds on behalf of the original party to the transaction.
4) Direct payment not passing through a foreign exchange bank
When paying the consideration for a current transaction, such as import payments, in an amount exceeding USD 10,000, the payment must be remitted through a foreign exchange bank.
If you must carry cash out and pay it directly, reporting is mandatory.

5. Foreign Exchange Transactions Act | Korea Customs Service to Conduct Regular Foreign Exchange Inspections

Under the Foreign Exchange Transactions Act, beginning in 2025, the Korea Customs Service will conduct regular foreign exchange inspections of companies that engage in foreign exchange transactions above a certain scale.
This represents a paradigm shift. The previous approach conducted foreign exchange investigations only when an illegal transaction was suspected, whereas the new approach emphasizes advance prevention and effective management.
[Companies Subject to Regular Inspection]
- Companies with a record of foreign exchange transactions above a certain scale
- Companies engaged in overseas direct investment
- Companies conducting capital transactions
- Companies conducting high-risk transactions such as set-off, third-party payment, or payment beyond the prescribed period
If a violation of the Foreign Exchange Transactions Act is detected, the company may be investigated by the Financial Supervisory Service, the Korea Customs Service, the police, and others, and a serious violation may lead to criminal proceedings, so advance prevention and a prompt response by the company are important.
