I want to know the relationship between invoice and tax. Please keep it simple and don't copy it. This is why the invoicer will lose money and how to check the tax according to the invoice.

Taxes and invoices are interdependent. Taxes are based on invoices. The more invoices, the more taxes. If enterprises pay more money, they will certainly be affected.

How to check taxes according to invoices;

There is not only one invoice, but each invoice has a different invoice. After the merchant issues an invoice to the consumer, the tax bureau will collect the tax of the enterprise according to the contents copied on other invoices. So if we want invoices, it will be difficult for businesses to evade taxes.
