Employer Costs and Employee Taxes in South Korea
South Korea splits social insurance costs roughly 50/50 between employer and employee, except for Industrial Accident Insurance which is 100% employer-funded. The NPS reform makes these rates a moving target through 2033.

Good to Know: The headline employer contribution of ~11% understates the real cost of hiring in South Korea. Add mandatory severance accrual (effectively 8.3% annually) and the picture changes: total employer cost runs closer to 19-20% of gross salary. By 2033, when NPS reaches 6.5% employer share, that figure will approach 22-23%. For a mid-level engineer earning KRW 5,000,000/month, that’s roughly KRW 1,100,000/month in employer costs today, rising to KRW 1,250,000 by 2033, before any salary increases.
