How to Calculate Take-Home Pay in China
Take-home pay in China equals gross income minus Individual Income Tax (个人所得税/IIT), the employee share of social insurance (pension ~8%, medical ~2%, unemployment ~0.2-0.5%), and the housing fund (住房公积金, typically 5-12%). The contribution base (缴费基数) for social insurance and the housing fund is tied to your city and the prior year's local average wage, so employees in Tier-1 cities like Beijing or Shanghai often see larger absolute deductions due to a higher contribution base cap.
