Paragraph 1 of Article 25 of the Law of the People's Republic of China on the Administration of Tax Collection stipulates that taxpayers must truthfully file tax returns in accordance with the time limit and contents stipulated by laws and administrative regulations or by tax authorities.
Article 32 of the Detailed Rules for the Implementation of the Law of the People's Republic of China on Tax Collection and Administration stipulates that if there is no tax payable within the tax period, tax returns shall also be made in accordance with the regulations. Therefore, taxpayers should also declare when they have no income.
Whether to declare zero or not depends on the relevant provisions of the tax (fee) approved by the tax authorities, which is not necessarily related to whether there is income. The declaration process of various taxes is the same as the normal declaration process, and the zero declaration of social security fees can only be handled with the signature of the tax administrator and the director.
