❓ Frequently Asked Questions (FAQ)

Q. When should a foreign worker in Korea choose the 19% flat tax rate?

Because the 19% flat tax (20.9% with local tax) disallows all deductions and tax-free allowances, standard progressive tax is cheaper for salaries under ~₩130,000,000. Above ~₩130M–₩140M, the 19% flat rate saves significant tax.

Q. Is there a cap on Korean National Pension contributions?

Yes, the monthly income base for National Pension is capped at ₩6,170,000, so the maximum employee pension deduction is ₩277,650/month.
