Both South Korea and Singapore sit in Asia & Pacific, but their tax structures take different paths. On a $150,000 gross, the effective tax burden in Singapore is roughly 10.8% higher than in South Korea — driven by differences in 4대보험 vs CPF, bracket structure, and personal allowance.
Same nominal gross applied to both tax systems. Currencies aren't FX-converted — compare structures, not purchasing power.
South Korea uses an eight-band income tax with a top rate of 45%, plus a 10% local income tax. The four mandatory insurances — national pension, health, employment, and long-term care — total around 9.4% for the employee. A standard earned-income deduction reduces the taxable base substantially.
Singapore's personal income tax is famously low — capped at 24% even for million-dollar earners. Citizens and Permanent Residents contribute 20% to the Central Provident Fund (CPF) for retirement, healthcare, and housing; the employer adds 17% on top. Foreign professionals on Employment Pass don't pay CPF.
