The sales profit rate of each industry is not equal, and there is no uniform regulation, so it is impossible to determine.

Proportion of tax revenue to sales revenue

If only turnover tax needs to be calculated, it is generally 3-6% according to different industries. Although the general taxpayer's VAT rate is 17%, it will not exceed 6% after deduction. If corporate income tax is to be increased, it should be linked to profits.

However, corporate income tax is also levied according to law, and the tax rate is 3-30% according to different industries.
