Retirement income tax calculator

This English page translates the Korean retirement income tax guide and keeps the same service-year deduction, converted salary, progressive tax, executive limit, interim settlement, local tax, and IRP comparison logic.

Service-year deduction

The Korean retirement-income calculation first subtracts non-taxable retirement income and then applies a service-year deduction. The model uses KRW 1 million per year up to five years, KRW 5 million plus KRW 2 million per year for years six to ten, KRW 15 million plus KRW 2.5 million per year for years eleven to twenty, and KRW 40 million plus KRW 3 million per year above twenty years.

The remaining amount is converted to annualized salary by dividing by service years and multiplying by 12. A converted salary deduction is then applied before the progressive tax bracket calculation.

Tax and special cases

The converted tax is scaled back to the actual service period to produce retirement income tax. Local income tax is 10 percent of the national retirement income tax.

Executives can be subject to a retirement-pay limit for the post-2020 period, using the executive salary and months after 2020. Interim settlement comparison is modeled separately because combining or separating retirement periods can change the final tax.

IRP pension receipt

The Korean guide also shows the effect of moving retirement pay into an IRP and receiving it as pension income. Pension receipt within 10 years can use 70 percent of the retirement-income tax burden, while receipt from year 11 onward can use 60 percent.

Use the result for withholding review, retirement settlement planning, and IRP timing. Final tax can differ when there are multiple employers, interim settlements, executive compensation limits, or non-taxable retirement items.
