Korea youth SME tax benefit calculator guide

This English page translates the Korean youth SME tax-benefit calculator and calls calculateYouthSmeTaxBenefit. It keeps the age test, military-service age deduction, earned-income tax calculation, 90% reduction, KRW 2,000,000 annual cap, local-tax reduction, and five-year timeline.

Eligibility and military-service deduction

The Korean source checks whether adjusted age falls within the youth SME tax-reduction age window. If military service months are entered, the model deducts service years up to the maximum military deduction used by the source before applying the age test.

Eligibility reasons are generated by the Korean function, but the English UI summarizes eligibility with English labels and keeps adjusted age and military deduction visible. This avoids displaying Korean data labels while preserving the exact eligibility branch.

Income tax before reduction

The calculator calculates gross salary after annual non-taxable income, earned-income deduction, earned income amount, personal deduction, standard deduction, taxable income, calculated tax, and marginal tax rate under the Korean 2026 bracket table.

Dependents matter because the source applies a personal deduction per person. The English page exposes dependents including the taxpayer so users can see how the taxable base changes before the youth SME reduction is applied.

90% reduction and KRW 2,000,000 cap

The youth SME reduction uses the Korean source reduction rate of 90% and the annual cap of KRW 2,000,000. If calculated reduction exceeds the cap, the result flags cap application and limits the reduction amount.

Local income tax reduction is calculated as 10% of the income-tax reduction. Total annual saving, monthly saving, before-tax amount, after-tax amount, and saving rate are all returned from the same feature library.

Five-year timeline and related support

The timeline projects estimated salary, annual saving, and cumulative saving over five years using the entered annual raise assumption. The five-year total is therefore not a static five-times-current-year shortcut.

The Korean result also includes related subsidy information. Actual availability can depend on business type, SME status, first employment date, prior benefit use, and National Tax Service review, so the calculator should be checked against employer and tax filings.
