Is it better to contract or be employed in South Korea?

At $100/hour against a salaried equivalent of $70/hour, 40 hours a week, contracting nets more than employment in South Korea: a contractor keeps about $147,960 against an employee's $123,760, a difference of $24,200. The break-even rate — where the two are equal — is about $84/hour. Income tax + four insurances; 19% flat election for foreign workers.

What hourly rate do I need to charge in South Korea?

To take home $100,000 a year after tax, health cover and unpaid time, you need roughly $91/hour, or a day rate around $725. That assumes $130,513 of gross revenue across 1440 billable hours.

Why is the contractor tax rate in South Korea different from the employee rate?

A contractor usually pays both halves of social contributions where an employer would otherwise pay one, and often buys health cover privately. Here that works out at about 23% effective for a contractor against 15% for an employee. Income tax + four insurances; 19% flat election for foreign workers.

How accurate are these South Korea figures?

The employee rate used here is 15%. The OECD's Taxing Wages series independently reports 16.5% of gross pay going to income tax plus employee social contributions for a single person on the average wage in 2025, and 13.3%–20.9% across earnings from two-thirds to two-thirds again above that. The rate here is checked against that range on every build and a figure outside it fails. It is still one blended rate where a real system has brackets, so treat it as an estimate: your actual liability depends on your regime, deductions and region.

Checked against the OECD

This page uses an employee rate of 15%. The OECD's Taxing Wages series independently puts income tax plus employee social contributions at 16.5% of gross pay for a single person on the average wage in 2025 — and the full tax wedge, which adds what the employer pays on top, at 24.9% of total labour cost.

The rate above is checked on every build against the range OECD measures across earnings from two-thirds of the average wage to two-thirds again above it, and a figure outside that range fails the build. The two are not expected to match exactly: this site carries one blended rate where a real system has brackets.
