For example, how does the tax bureau know the turnover of a hotel this month? Just based on how many invoices this hotel has issued this month?

1. How to determine (operating income) is usually to evaluate or collect materials related to your income, such as collecting business registers or adopting other legal and reasonable methods.

2. The invoice must be written off to the tax bureau every month, and you can't buy a new invoice without writing it off. So the tax bureau knows the purchase and sale of your invoices, and the declared income is also recorded. How can the tax bureau not know that the so-called tax control depends on tickets? Moreover, to promote online invoicing, information will be sent to the server of the tax bureau every time one is opened.

Don't think too much about the invoice. It is absolutely impossible to underreport or fake tickets. The only thing I can think of is underreporting operating income, but I really want to find out anyway, just to see the depth of the investigation. . . The consequences of the law are on your own.
