Korea Salary Take-Home Pay Calculator (2026 Social Insurance and Income Tax)
2026 rates · Last checked · Official sources are listed under the basis of calculation below
Enter your annual salary and this estimates the amount that lands in your bank account each month. It subtracts the employee's share of the four major social insurances for 2026 (4대보험: national pension, health insurance, long-term care insurance and employment insurance) and the income tax from the simplified withholding tax table (근로소득 간이세액표, Annex 2 of the Income Tax Act Enforcement Decree). This is an estimate, not an official calculation, and it may differ from your actual payslip.
Show calculation steps
Step 1, monthly pay. Annual salary ÷ 12 (fractions of a won dropped). Subtracting the non-taxable amount gives the base for insurance premiums and income tax.
Step 2, national pension. Standardized monthly income × 4.75%. The standardized monthly income (기준소득월액) drops amounts below 1,000 won, and is set to KRW 410,000 if lower than that and to KRW 6,590,000 if higher than that.
Step 3, health insurance. Monthly pay × 7.19% ÷ 2, which is 3.595%. The monthly cap of KRW 9,183,480 and floor of KRW 20,160 on the total premium are applied.
Step 4, long-term care insurance. Health insurance premium × 0.9448% ÷ 7.19%.
Step 5, employment insurance. Monthly pay × 0.9%.
Step 6, income tax. Using the monthly pay and the number of dependents, look up the tax in the matching column of Annex 2, then subtract the deduction for children aged 8 to 20. Local income tax (지방소득세) is 10% of the income tax.
Each amount is rounded down to the nearest 10 won. Example: with an annual salary of KRW 36,000,000, non-taxable pay of KRW 200,000 and 1 dependent (yourself), monthly pay is KRW 3,000,000 and taxable pay is KRW 2,800,000. Pension KRW 133,000, health insurance KRW 100,660, long-term care KRW 13,220, employment insurance KRW 25,200, income tax KRW 56,800 and local income tax KRW 5,680 add up to KRW 334,560, so monthly take-home pay is KRW 2,665,440.
2026 deduction rates
| Item | Total rate | Employee's share | Basis |
|---|---|---|---|
| National pension | 9.5% | 4.75% | National Pension Act addenda (April 2, 2025), Article 4: 475/10,000 for 2026 |
| Health insurance | 7.19% | 3.595% | National Health Insurance Act Enforcement Decree, Article 44: 719/10,000 |
| Long-term care insurance | 0.9448% | Health premium × 0.9448/7.19 | Act on Long-Term Care Insurance for the Aged, Article 9, and its Enforcement Decree, Article 4 |
| Employment insurance (unemployment benefit) | 1.8% | 0.9% | Premium Collection Act, Article 13 (2), Enforcement Decree, Article 12 |
| Local income tax | 10% of income tax | Local Tax Act, Article 103-13 | |
The national pension contribution rate is set to rise by 0.5 percentage points each year from 2027 and reach 13% in 2033, so this table will need updating next year. Industrial accident insurance is left out because employees do not pay it. The employment stability and vocational skills development premium within employment insurance is paid by the employer only.
The withholding tax table is used as written, with no approximation
The income tax in this calculator is not a rough formula. The 646 rows from KRW 770,000 to KRW 10,000,000 and the columns for 1 to 11 dependents from Annex 2 of the Income Tax Act Enforcement Decree (amended February 27, 2026, applying to withholding from March 1, 2026) were copied from the original PDF. After copying, every cell was checked again by two separate methods, and no differing cell was found.
For monthly pay above KRW 10,000,000, the formulas under the table are used. For example, for pay above KRW 10,000,000 up to KRW 14,000,000, the tax is (tax for the KRW 10,000,000 row) + (the excess × 98% × 35%) + KRW 25,000. The cases with more than 11 dependents and the deduction for children aged 8 to 20 (KRW 20,830 for 1 child, KRW 45,830 for 2 children, and KRW 45,830 plus KRW 33,330 for each child beyond 2 for 3 or more) are also calculated by the Annex's rules.
The withholding rate option is included because Article 194 of the Income Tax Act Enforcement Decree lets an employee choose 80% or 120% of the table amount. This calculator multiplies the tax after the child deduction by the rate. It chose this order because no text fixing the order of deduction and rate was found in the original, so if you combine 80% or 120% with the child deduction, the actual result may differ.
What is an estimate here
The rates and table values are exactly as in the official sources, but the result is an estimate because of the assumptions below. Where the size of the error can be stated, a number is given; where it depends on the person, it says so.
- Annual salary ÷ 12 assumption: If you receive bonuses separately or your allowances vary from month to month, the monthly amounts will differ. The error depends on your pay structure and cannot be given as a number.
- Income base for premiums: Actual national pension uses the standardized monthly income that was reported, and health insurance uses the monthly remuneration your workplace reported. In a year when your salary rises, less may be deducted than this calculation and then settled later. The error depends on the size of the raise.
- Rounding: Each item is rounded down to the nearest 10 won. A company that calculates health insurance as a total and then splits it may differ by less than 10 won per item.
- Long-term care ratio: From the premium for November 2026 (the month containing the law's effective date, November 27, 2026), the amended law rounds the ratio to the health insurance rate at the fifth decimal place. This calculator does not round, so it may differ by less than 20 won.
- Year-end tax settlement not reflected: The simplified table is the amount withheld in advance each month. Your real tax for the year is decided at the next year's year-end tax settlement (연말정산), which takes into account card spending, medical expenses, pension savings and so on, and produces a refund or an extra payment.
- Period: The national pension ceiling and floor are the values for July 2026 to June 2027. From January to June 2026 the floor was KRW 400,000 and the ceiling KRW 6,370,000. Annex 2 also applies to withholding from March 2026.
Example table by annual salary
Calculated with KRW 200,000 non-taxable pay, 1 dependent (yourself) and no child deduction.
| Annual salary | Monthly pay | National pension | Health + long-term care | Employment insurance | Income tax + local tax | Monthly take-home |
|---|---|---|---|---|---|---|
| KRW 30M | 2,500,000 | 109,250 | 93,540 | 20,700 | 32,070 | KRW 2,244,440 |
| KRW 36M | 3,000,000 | 133,000 | 113,880 | 25,200 | 62,480 | KRW 2,665,440 |
| KRW 40M | 3,333,333 | 148,810 | 127,440 | 28,190 | 93,080 | KRW 2,935,813 |
| KRW 50M | 4,166,666 | 188,380 | 161,330 | 35,690 | 209,680 | KRW 3,571,586 |
| KRW 60M | 5,000,000 | 228,000 | 195,230 | 43,200 | 338,160 | KRW 4,195,410 |
| KRW 80M | 6,666,666 | 307,130 | 263,010 | 58,190 | 671,250 | KRW 5,367,086 |
| KRW 100M | 8,333,333 | 313,020 | 330,810 | 73,190 | 1,085,390 | KRW 6,530,923 |
The national pension on the KRW 100 million row is almost the same as on the KRW 80 million row because it hits the ceiling of KRW 6,590,000 on the standardized monthly income. For the same KRW 60 million salary, with 3 dependents including 1 child aged 8 to 20, income tax is lower and monthly take-home pay becomes KRW 4,323,230.
How to use
Enter your annual salary before tax. If your contract includes severance pay in the salary, enter the amount without the severance share. Non-taxable pay is the total of items on your payslip that carry no tax, such as meal allowance and child care allowance. Article 12, item 3 of the Income Tax Act sets as non-taxable, for example, a meal allowance of up to KRW 200,000 a month for employees who are not provided meals, and child care related pay of up to KRW 200,000 a month per child aged 6 or under.
For the number of dependents, count yourself and your spouse as 1 each. In the children field, enter only children aged 8 to 20 among your dependents.
When this calculation does not apply
- Age 60 or older: Mandatory national pension enrollment as a workplace member applies to ages 18 up to under 60 (National Pension Act, Article 8). If you do not pay into it, you take home the pension amount more than shown here.
- Newly hired after age 65: You do not pay the employment insurance unemployment benefit premium (Premium Collection Act, Article 13 (3)).
- Health insurance reductions, foreign nationals, daily workers, and pay that includes tuition support: The calculation rules differ, so the result will differ from this one. If you are a foreign national, check with your employer's payroll staff.
- Income tax reduction for employees of small and medium-sized companies: If you receive this reduction, your actual income tax is lower than the table amount. This calculator does not reflect it.
Frequently asked questions
Why is my take-home pay different from a friend's with the same salary?
It differs if non-taxable items, the number of dependents, the number of children aged 8 to 20, the withholding rate or the way bonuses are paid are different. Even with a KRW 60 million salary, as in the example above, take-home pay is KRW 4,195,410 a month for 1 person and KRW 4,323,230 a month with 3 dependents and 1 child.
If I set the withholding rate to 80%, does my tax go down?
Only the amount withheld each month goes down; your tax for the year stays the same. At year-end settlement, your refund may be smaller or you may have to pay extra by the amount that was not withheld. In the KRW 50 million example, monthly take-home pay is KRW 3,613,536 at 80% and KRW 3,529,656 at 120%.
When do my deductions change if my pay goes up?
Income tax changes immediately because the table is looked up using the monthly pay for the month it is paid. Premiums are based on the reported remuneration, so the timing depends on your company's report of the pay change or the following year's settlement.
How is severance pay calculated?
It is not included in this calculator. Use the Severance Pay Calculator, which works from your length of service and your last 3 months of wages.
Why might this differ from the National Tax Service result?
The income tax column uses the same Annex 2 values. If the monthly pay or number of dependents you enter is different, you read a different row. The four social insurances follow the remuneration your company reported, so your actual payslip is the most accurate.
