Compared with remaining freelancer-only for the same gross income.

Calculates the year a Korean freelancer becomes an employee using the same mixed business-income, earned-income, 3.3 percent withholding, insurance deduction, tax-credit, and scenario comparison logic as the Korean hook. This English calculator calls the same pure tax calculation function used by the Korean page. Inputs and labels are translated; the formula is not replaced by a generic value-times-rate stub.

Freelancer to employee transition tax calculator

This page translates the Korean guide for the year a freelancer becomes an employee and preserves the mixed business-income, earned-income, withholding, deduction, credit, and scenario-comparison calculation.

Mixed income year

A freelancer who becomes an employee during the year can have both business income and employment income in the same comprehensive income return. The model separates freelancer gross income, deductible expenses, employee salary, and earned-income deduction.

Freelancer withholding uses the 3.3 percent total withholding structure, made up of 3 percent national income tax and 0.3 percent local income tax. Employee withholding is estimated separately unless an override is entered.

Deductions and credits

The calculation applies personal deduction, national pension deduction, health and employment insurance deduction, earned-income tax credit on the employment portion, child tax credit, pension savings and IRP credit, medical, education, donation, monthly rent, and optional standard credit handling.

Because the earned-income tax credit is based on the employee portion, the same annual gross income can produce a different result depending on the transition month and how much income was earned before and after employment.

Scenario comparison

The result compares a freelancer-only year, an employee-only year, and the actual transition year. The transition effect shows whether the mixed year increases or decreases tax relative to staying freelance for the same gross income.

Use this before year-end settlement, pension deposits, or withholding review. A refund can turn into additional tax when freelancer expenses, insurance paid before employment, or employee withholding are entered incorrectly.
