Comprehensive income keeps Korean 2025 brackets from 6 percent to 42 percent in this utility lib, local tax, separate taxation for financial/capital/pension income, and pension/IRP deduction limits. This English calculator calls the Korean page feature lib directly. The UI is translated, but the numbers come from the same pure calculation path instead of a generic value-times-rate stub.

Comprehensive income tax calculator

This English guide translates the Korean comprehensive-income calculator for the May filing season, preserving salary, business, capital gains, interest, dividends, pension, other income, deductions, separate taxation, and optimization.

What comprehensive income combines

Comprehensive income can combine salary, business income, interest, dividends, pension, other income, and in some scenarios capital-gains amounts. The Korean utility keeps separate fields because each income class has a different deduction or separate-tax rule.

Financial income is especially important because the KRW 20 million threshold can move interest and dividends into comprehensive taxation. Other separate-tax choices can also change the optimal method.

Deductions and tax rates

The calculator keeps earned-income deduction, business-income deduction, the KRW 2.5 million capital-gains deduction, dividend deduction, pension-income deduction, KRW 1.5 million basic deduction, spouse and dependent deductions, pension saving, personal IRP, insurance, medical, education, and donation deductions.

The utility applies progressive tax brackets and then adds local income tax. The result also shows comprehensive taxation versus separate taxation, tax savings, total tax rate, and monthly net income.

Optimization before filing

Use this page before the May comprehensive income tax return, before year-end pension or IRP deposits, or before deciding whether additional financial income should be realized this year.

The final filing should be checked against withholding receipts, business ledgers, expense evidence, pension certificates, donation receipts, and current National Tax Service guidance. The calculator is a faithful scenario engine, not a document validator.
