At present, most of the taxes in China are fixed by votes, that is, how many invoices you need for catering services in a month, and then according to this, the turnover will be increased by 31% (this ratio varies from place to place, and it is 31% here), and then the turnover multiplied by the tax rate is your fixed tax this month. The tax rate is specifically like this. Business tax, urban construction tax and education fee are added by 5.5%, and personal income tax is 3%. You can ask me if there is anything unclear.
