South Korea Commercial Late Fee Regulations: 6% Statutory Rate, 3-Month Termination Threshold, and Management Fees

Late rent fees for commercial leases in South Korea are governed by a higher statutory interest rate than residential leases, and the termination threshold is set at 3 months of arrears rather than the residential standard of 2 months.

Interest Rates

Statutory Rate (No Contractual Rate)

Commercial leases are classified as commercial (business) transactions, so the Commercial Act rate of 6% applies rather than the Civil Act rate of 5%.

Contractual Rate

Lease agreements may specify a higher rate. Rates of 10%–20% per annum are common in commercial lease practice.

Legal Cap

Calculation

Late fee = Overdue rent × Annual rate × (Days overdue / 365)

Best Practices for Landlords

1. Specify a late fee rate in the lease — the statutory 6% may not provide adequate incentive for timely payment
2. Stay within the 20% cap — courts can void or reduce excessive rates
3. Track cumulative arrears precisely — the 3-month threshold is cumulative
4. Separate rent and management fees in records — distinct billing for proper legal treatment
5. Document all collection efforts — text, email, and certified mail
6. Deduct arrears at lease termination — not during the lease term unless agreed
