Freelance withholding and net pay calculator

For Korean resident personal-service business income subject to 3% national withholding plus local tax (3.3% combined before rounding). This is advance withholding, not your final annual tax. Not every freelance contract qualifies. VAT, other-income contracts, nonresidents and platform fees need separate treatment. National/local tax drop amounts below KRW 10. Enter confirmed insurance and fees in other deductions; they are not assumed exempt.

Applied to the full gross amount in this payment; then fixed deductions are subtracted. This is arithmetic only, without tax brackets, exemptions or statutory insurance. Do not enter the same deduction twice.
