For most foreign groups, money moving between headquarters and the Korean subsidiary is routine treasury work: capital goes in, fees and royalties go out, an intercompany loan covers a shortfall, and balances get netted at year-end. Korea’s Foreign Exchange Transactions Act treats several of these arrangements as regulated transactions that must be reported before they happen. Violations are rarely deliberate. They usually come from a treasury practice set at headquarters and repeated every quarter for years until an inspection finds it.
How the Act Sorts Intercompany Money Flows
Current Payments Versus Capital Transactions
Payments for goods and services can generally be made freely through a foreign exchange bank with supporting documents. Capital transactions, such as loans, deposits, guarantees, and equity, generally require a report in advance.
How the Payment Is Made Matters Separately
An ordinary service payment can still need a report because of how it is settled. Netting, paying someone other than the counterparty, paying far outside normal terms, and moving money outside the banking system are all regulated “payment methods.” Most intercompany problems come from this layer.
Where Equity Fits
Capital contributions usually go through a foreign direct investment notification under the Foreign Investment Promotion Act. That filing also protects the parent’s right to send dividends and exit proceeds home later.
Intercompany Loans: The Most Common Unreported Capital Transaction
Borrowing From the Parent
A subsidiary borrowing from its parent or an overseas affiliate must report in advance, generally to its designated foreign exchange bank. Borrowing above an annual aggregate of USD 50 million, a threshold raised in 2023, goes through a different reporting route. A loan from the parent of roughly five years or more can instead be structured as foreign direct investment.
Lending Upstream to the Parent
A Korean subsidiary lending to its parent or a regional treasury entity also has to report in advance. These loans raise tax issues too, including arm’s-length interest.
Amendments, Extensions, and Rollovers
Extending, increasing, repricing, or converting a reported loan can each require an amended report. Automatic rollovers at headquarters often create a new violation every time.
Cash Pooling and Guarantees
Taking part in a group cash pool is an ongoing capital transaction. Guarantees given to or received from group companies can also be reportable.
Netting: The Violation Hiding Inside Routine Reconciliation
Why Offsetting Is Regulated
Offsetting import payables against service receivables removes a cross-border payment from the banking record. Netting between the subsidiary and one foreign party generally has to be reported to the designated foreign exchange bank. Netting across several group entities generally has to be reported to the Bank of Korea.
The Narrow Exemptions
Exemptions cover very small amounts, certain trade arrangements, commissions directly tied to an export or import, and tax withheld on cross-border income. A group-wide monthly netting cycle usually falls outside them.
Why This Is Easy to Miss
Netting happens in the group’s accounting system, so the Korean finance team may not know it is happening until the intercompany ledger and the bank records fail to match.
Paying on Someone Else’s Behalf
Third-Party Payments
Paying a regional affiliate for services the parent provided, or paying a vendor on headquarters’ behalf, is a third-party payment. Above small-amount thresholds, it must be reported in advance.
Cost Recharges and Shared Service Invoices
Invoices from a shared service center for services an affiliate delivered need a clear record of who the actual counterparty is. The same documents support the tax deduction.
Timing Outside Normal Terms
Large advance payments, or intercompany payables left open for years, can also be a regulated payment method.
What Happens When a Violation Is Found
The Sanctions Ladder
- Capital transaction reporting failures up to USD 50,000 are generally handled with a warning.
- Larger violations bring administrative fines.
- Criminal penalties apply above KRW 2 billion for capital transaction violations and KRW 5 billion for payment method violations. These thresholds date from July 2023.
- Each unreported transaction counts separately, so a long-running arrangement can reach these thresholds quickly.
The Tightening Coming Into Force
An amendment promulgated on June 2, 2026 takes effect six months later. It makes payment procedure violations committed to obtain improper gains a criminal offense, punishable by up to one year’s imprisonment or a fine of up to KRW 100 million.
Voluntary Correction
Violations the company finds and fixes itself are treated far more leniently than those found in an inspection. The fine for late-report violations was cut from KRW 7 million to KRW 2 million in 2023.
Who Finds These Problems
Violations come to light through foreign exchange bank reviews, Korea Customs Service investigations, Financial Supervisory Service inspections, and tax audits.
Practical Sequencing for a Foreign Group’s Korea Treasury Setup
- Map every intercompany flow by transaction type and settlement method.
- Report capital transactions in advance, and file amended reports when terms change.
- Decide whether Korea joins group netting, and put reporting in place before the first cycle.
- Invoice from the actual counterparty so recharges don’t become third-party payments.
- Run capital contributions through the FDI notification.
- Correct historic gaps voluntarily before an inspection or audit finds them.
