Korean tax, explained.

연말정산, 종합소득세, 부가세 and the rest of the Korean system — what each one is, who it applies to, and what decides the number.

Year-End Tax Settlement (연말정산)

Korea settles employees' income tax once a year in 연말정산. What it is, what your employer needs, and why a refund is not a bonus.

Global Income Tax Return (종합소득세)

Korea's May filing season for freelancers, business owners and anyone with income beyond one salary. Who must file, and what gets combined.

Value-Added Tax in Korea (부가가치세)

Korean VAT is 10% and is money you collect on the state's behalf. How the filing cycle works and why tax invoices decide your bill.

Registering a Business in Korea (사업자등록)

사업자등록 is the first tax decision, not paperwork. Sole trader vs corporation, general vs simplified, and why the timing matters.

Income Tax for Foreign Residents in Korea

Working in Korea on a foreign passport: what Korea taxes, the flat-rate election available to foreign workers, and the five-year rule.

How Severance Pay Is Taxed (퇴직소득세)

Korean severance is taxed on its own schedule, not added to your salary income — and length of service is what softens the rate.
