Calculation of taxable income of wages and salaries: The taxable income is equal to the monthly gross income minus the exemption amount (currently 5,000 yuan), and then minus special deductions (such as three insurance and one fund: personal pension, medical, unemployment and housing fund) and special additional deductions, as well as other deductions determined by law.

3. Payroll tax calculation: Payroll tax is equal to taxable income multiplied by the payroll tax rate. Individual income tax rates vary depending on the taxable income range, ranging from 0% to 45%.
