Unpaid Wages in Korea: How Long Before It Becomes a Legal Issue?

Is Even One Day of Late Pay Considered Unpaid Wages?

Many workers wonder, when their paycheck arrives a few days late, "Does this count as unpaid wages?" The short answer is: if wages are not paid even one day after the designated payday, it legally constitutes unpaid wages (임금체불).

Article 43 of the Labor Standards Act (근로기준법 제43조) requires that wages be paid at least once a month, on a fixed date, directly to the worker in currency. The moment an employer misses the payday set in the employment rules or employment contract, they are in a state of wage default. The idea that "a few days is fine" simply does not hold up legally.

Note for foreign workers: Your employment contract may specify a payday different from the statutory default — but once that contractual date passes, the same legal rules apply.

Statute of Limitations for Unpaid Wages: You Must Claim Within 3 Years

Wage claims are subject to a 3-year statute of limitations (소멸시효) under Article 49 of the Labor Standards Act (근로기준법 제49조). This means that if 3 years pass from the date wages were not paid, the legal right to claim them expires.

For example, wages unpaid in May 2023 must be claimed by May 2026. After 3 years, even if you file a complaint with the Labor Office, the employer can invoke the statute of limitations and it becomes very difficult to obtain relief. The longer you wait, the more disadvantaged you become — act as quickly as possible.

Severance pay (퇴직금) claims are subject to the same 3-year statute of limitations under Article 10 of the Act on the Guarantee of Workers' Retirement Benefits (근로자퇴직급여 보장법 제10조).

Delay Interest That Grows With the Length of Non-Payment

When wages go unpaid, you are entitled to more than just the principal amount. Under Article 37 of the Labor Standards Act (근로기준법 제37조) and its Enforcement Decree, if wages or severance pay remain unpaid for more than 14 days after resignation, annual delay interest of 20% applies. For wages unpaid during active employment, you may claim the statutory civil interest rate of 5% per annum.

The longer the period of non-payment, the greater the total amount the employer must pay — so early resolution is in the employer's interest as well.

When and Where to File a Complaint

Wage complaints are filed by submitting a written complaint (진정서) to the Regional Employment and Labor Office (지방고용노동청) with jurisdiction over the workplace. You can also file online through the Ministry of Employment and Labor's civil petition portal at minwon.moel.go.kr.

A common question: "Can I file a complaint while still employed?" — Yes, you can. It is a misconception that you must resign first. If the payday has passed while you are still employed, you may file a complaint immediately.

After the complaint is filed, a labor inspector investigates. If the employer acknowledges the unpaid wages and pays them, the case is closed. If the employer refuses to pay, the case is referred to the prosecutor's office and the employer may face criminal punishment — up to 3 years in prison or a fine of up to 30 million won (₩30,000,000) under Article 109 of the Labor Standards Act (근로기준법 제109조).

The Wage Claim Guarantee System: When the Employer Has No Money

If the employer is insolvent or unable to pay, you can use the wage claim guarantee system (체당금 제도), under which the government pays wages on the employer's behalf. By applying to the Ministry of Employment and Labor or the Korea Workers' Compensation & Welfare Service (근로복지공단), you can receive up to 3 months of unpaid wages and 3 years of unpaid severance pay.
