Legal analysis: the deduction of payroll tax is the income from wages and salaries MINUS five insurances and one gold, and then the difference between the deductions is multiplied by the applicable tax rate and then the quick deduction is deducted. The threshold of payroll tax is 5,000 yuan, and the calculation of excess progressive tax rate is that the tax payment is the product of taxable income and tax rate for the whole month minus quick deduction. The actual salary is the difference between the payable salary and the four gold and tax payment.
