South Korea's tax service expects to publish crypto guidance in November, before a 22% tax on gains above 2.5 million won starts on January 1, 2027. Staking, airdrops, hard forks and DeFi are still under review, so exchanges are building against rules not yet written.

Korean business owners aged 60 or older rose by 184,226 in the year to August, more than the country's 133,382 net gain in all operators, tax data show. Every age group under 60 shrank, so the count now rests on people past retirement age, many of them working because their pensions fall short.
