1, each income is less than 4,000 yuan;
Taxable amount = (-800 per income) * 20% (for example, you just paid 4000 and actually got 3360).
2, each income more than 4000 yuan:
Taxable amount = every income *( 1-20%)*20%
3, the taxable income of each income of more than 20000 yuan:
Taxable amount = every income *( 1-20)* applicable tax rate-quick deduction.
For the part exceeding 20000-50000, the tax rate is 30%, and 2000 will be deducted quickly.
For the part exceeding 50,000 yuan, the tax rate is 40%, and 7000 yuan is deducted for quick calculation.
