South Korea salary calculator 2026

South Korea has one of the longest progressive tax scales in this dataset, eight bands running from 6% to 45%, yet the typical employee never gets near the top of it. What dominates a Korean payslip is the bundle known locally as the four major insurances, which the model collapses into a single line of just under 10% of gross. The result is a deduction pattern that looks surprisingly steady from the minimum wage up to twice the average salary.

Eight brackets, one basic deduction

National income tax on employment income is progressive. Annual taxable income up to 14,000,000 KRW is taxed at 6%, then 15% up to 50,000,000, 24% up to 88,000,000, 35% up to 150,000,000, 38% up to 300,000,000, 40% up to 500,000,000, 42% up to 1,000,000,000 and 45% above that. The model deducts a basic personal allowance of 1,500,000 KRW a year before applying the scale.

Two things a real Korean assessment does are not in the model. First, wage earners receive an earned income deduction that scales with salary, plus an earned income tax credit, and both are considerably more generous than the flat basic allowance used here. Second, a local income tax is charged on top as a fraction of the national bill. The two effects pull in opposite directions, so the tax line in the table is a reasonable middle estimate rather than a precise withholding figure. Employers withhold monthly from a simplified table and settle the difference in the year-end tax settlement.

The four insurances

The single social line of 9.71% in the model represents the employee share of the national pension, national health insurance with its long-term care surcharge, and employment insurance; the fourth insurance, industrial accident cover, is paid by the employer alone. These contributions are deducted before income tax is calculated, which is why the taxable base on the payslip is smaller than gross. In reality the pension contribution is capped and health insurance rates are revised each year, so the real percentage drifts a little from 9.71%, especially at high salaries. The contributions guide explains what each element funds.

Worked examples

Between the minimum wage and the average salary the total deduction rises only three points, from 17.4% to 20.5%, because the insurances are a flat percentage and most of the income sits in the 6% and 15% bands. The crossover is worth noticing: at the minimum wage the insurance line is bigger than the tax line, at the average they are roughly equal, and at 8,000,000 KRW income tax is half as large again as the insurances. That is the 24% band starting to matter. At the minimum wage in particular the model probably overstates income tax, since the earned income deduction would shelter a large part of a salary that size.

What the employer adds

The employer matches the pension and health contributions, pays the whole of industrial accident insurance and a larger slice of employment insurance. The model puts the employer rate at 10.85% of gross: 488,250 KRW a month on the 4,500,000 KRW average salary, for a total cost of 4,988,250 KRW. Combined with the employee's 436,950 KRW share, roughly 925,000 KRW of the monthly cost of an average job flows into the insurance funds. Statutory severance pay, which accrues with length of service, sits outside both the payslip and this model.

VAT

Korea's value added tax is a single 10% rate with no reduced bands, so 100 KRW of goods becomes 110 KRW with tax. Categories such as unprocessed food, medical services and education are exempt rather than reduced. The VAT calculator covers the standard rate in both directions.

The 52-hour week and the holiday calendar

The Labour Standards Act sets a 40-hour, five-day week of 8-hour days. The statutory ceiling the model uses is 52 hours, the much debated limit that combines the standard week with the maximum permitted overtime.

The 2026 calendar in the model contains 8 fixed-date holidays, but only 4 of them land on a weekday, so it counts 257 working days. The national ones are distinctive: Independence Movement Day on 1 March, Liberation Day on 15 August, National Foundation Day on 3 October and Hangul Day on 9 October, which celebrates the Korean alphabet. What the model omits are the lunar holidays, Seollal and Chuseok, plus Buddha's Birthday and the substitute days granted when a holiday falls at the weekend. The working days calculator therefore counts a few more working days than an office calendar would.

Where the estimate is strong and where it is weak

The bracket rates, the insurance percentage and the employer rate are faithful to the statutory framework, so the ranking of one salary against another is dependable. The tax line itself is the softest part: the missing earned income deduction and tax credit push the estimate up, the missing local income tax pushes it down, and neither is modelled. Treat the net figure as accurate to within a few percent for a first comparison against Japan or Taiwan, and use the year-end settlement, not this page, for anything that needs to be exact.
