Calculates Korean tax for a Korea-resident remote worker paid by an overseas employer with the same income classification, exchange-rate conversion, employment-vs-business comparison, progressive tax, foreign tax credit, retirement savings credit, social insurance, VAT zero-rate notes, and calendar logic as the Korean calculator. 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.

This page translates the Korean remote worker tax guide for a Korea-resident worker paid by an overseas employer and preserves classification, exchange-rate, income tax, foreign tax credit, social insurance, VAT, and filing calendar logic.

Employment or business income

The Korean model classifies income as employment or business by contract type and work factors such as supervision, regular salary, exclusivity, and use of own equipment. Uncertain cases are simulated both ways.

Foreign-currency pay is converted to KRW using the selected exchange-rate method. The result then applies Korean employment income deduction or business expense deduction, not a generic foreign-salary percentage.

Tax credits and insurance

The income tax calculation includes the KRW 1.5 million basic exemption, pension and health-insurance deductions, progressive tax brackets, standard tax credit, foreign tax credit, and retirement savings credit. Retirement savings credit is limited by the KRW 9 million payment cap and uses 12 percent or 15 percent depending on income level.

Social insurance is estimated with national pension at 9 percent and the Korean monthly income floor and cap, plus health insurance and long-term care. The model uses national pension monthly income bounds of KRW 370,000 and KRW 6.17 million.

Business registration and filing calendar

When the income is treated as business income and a Korean business registration exists, overseas service revenue can be modeled with zero-rate VAT treatment. Actual expenses, simple expense rate, and standard expense rate can produce different taxable income.

The calculator also produces a filing calendar for comprehensive income tax in May, local income tax, possible VAT filings, insurance payments, interim prepayment, and overseas financial account reporting. Use it to plan filings before the foreign employer issues year-end documents.
