South Korea (Asia & Pacific) and New Zealand (Africa & Oceania) operate very different payroll systems, which makes a direct salary comparison interesting. On a $90,000 gross, the effective tax burden in New Zealand is roughly 14.0% higher than in South Korea — driven by differences in 4대보험 vs ACC, 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.
New Zealand keeps it simple: five PAYE income-tax brackets plus a 1.6% ACC Earners' Levy that funds accident cover. There's no separate social-security tax. KiwiSaver is opt-in (3–10% employee, 3% employer) and not included here. Healthcare is funded from general taxation.
