I am a freelance financial consultant. Do I have to pay tax if I stamp the official seal on the receipt?

There are two kinds of receipts. First, if it is income, it is unreasonable and not allowed. If it is a current payment, it is ok. You are a freelancer. If you get legal procedures, such as business license and tax registration, then your income will be invoiced to the other party. First, you will receive quota invoice from the tax bureau. In another case, if you open an online version of the machine, the other party will not accept the receipt, because the invoice must have a tax producer seal, and the receipt is invalid. Whoever uses it for accounting tax inspection will be fined; As for paying taxes, since you are an individual, the tax should be approved for you, or an invoice issued by an online version machine, and you should pay taxes according to your actual income (but there is a minimum income).
