Under South Korea’s National Health Insurance Act, family dependents pay ₩0 in healthcare premiums under an employed family member. However, earning even ₩1 of taxable net business income with a business registration triggers automatic disqualification.
💡 3-Minute BriefCore Guidelines
- Registered Business: Net income exceeding ₩0 immediately strips dependent status.
- Unregistered Freelance (3.3%): Allowed up to ₩5,000,000 in net annual business income.
- Contract Termination Defense: Submitting a Certificate of Termination (해촉증명서) voids regional premium bills for one-off freelance gigs.
