Korea tax wedge & take-home pay
Asia · OECD Taxing Wages, 2023 data · Low wedge
In Korea, the total tax wedge on a single average worker is 24.6% of total labour cost (ranked #32 of 38 OECD countries) — 10.3 points below the OECD average of 34.9%. That wedge is made of income tax 6.8% of gross, employee social security 9.4% of gross and employer social security 11.1% of labour cost. The worker keeps a net 83.8% of gross pay as take-home. These are modelled OECD averages for a representative worker, not your personal tax.

How Korea's labour cost splits
For every unit an employer in Korea spends on an average single worker, this is roughly where it goes — net pay versus the three components of the wedge:
- Net take-home pay: 74.3%
- Income tax: 6.2%
- Employee social security: 8.5%
- Employer social security: 11.1%
- Net take-home pay: 75.8%
- Income tax: 4.7%
- Employee social security: 8.5%
- Employer social security: 11.1%
Income tax and employee contributions are reported by the OECD as a share of gross wage; we rescale them onto total labour cost so the four segments sum to 100%. Source: OECD Taxing Wages, 2023 data.

What the Korea tax wedge means
The tax wedge answers a simple question: of everything it costs to employ an average worker in Korea, how much never reaches the worker because it goes to income tax and social-security contributions? Here that share is 24.6%, which reads as a below-average labour-tax burden. Crucially, it includes employer social-security contributions (11.1% of labour cost) that don't show up on a payslip — so the headline burden is larger than the "net tax rate" a worker sees (16.2% of gross). For a one-earner family with two children the wedge falls to 19.1% once child-related benefits and reliefs are counted.

Frequently asked questions
What is the tax wedge in Korea?
For a single average worker with no children, the total tax wedge in Korea is 24.6% of total labour cost (OECD Taxing Wages, 2023 data). That is 10.3 points below the OECD average of 34.9%. It combines income tax (6.8% of gross), employee social security (9.4% of gross) and employer social security (11.1% of labour cost). It is a modelled average, not your personal tax.
How much take-home pay does an average worker keep in Korea?
An average single worker in Korea keeps about 83.8% of their gross wage as net take-home — a net personal average tax rate of 16.2% (income tax plus employee social-security contributions). In USD PPP terms that is roughly $55,956 net from $66,806 gross. Employer social-security contributions of 11.1% sit on top of the wage and never appear on the payslip.
Does Korea have high employer social-security contributions?
Employer social security in Korea runs at 11.1% of total labour cost for an average single worker, ranking #26 of 38 OECD countries on that measure. Employer contributions are part of the tax wedge but are invisible on the payslip — they raise the cost of hiring without raising gross pay.
Is the tax wedge lower for families in Korea?
Yes — for a one-earner married couple with two children the tax wedge in Korea is 19.1%, versus 24.6% for a single worker, because child benefits and family tax reliefs reduce the net burden. The gap (5.5% of labour cost) is one measure of how much a country's tax-benefit system supports families.

Not tax advice. Figures model a representative average worker at 100% of the country's average wage — not your personal situation. Your actual tax and take-home depend on your income level, brackets, allowances, family status and local rules. Verify with Korea's tax authority and a qualified adviser.
