Prepare the following information: official seal, self-employed business license, identity information of the person in charge of the business license, and open a tax account with the tax bureau. Generally speaking, it is easier for individual industrial and commercial households to declare and pay taxes than companies, and individual industrial and commercial households levy fixed taxes. In other words, for individual industrial and commercial households, if the invoiced amount is less than 30,000 yuan, no tax will be generated and there is no need to declare and pay taxes.
