Can the jewelry bought in the mall be deducted from the tax increase invoice?
You can't. Inquire about the network according to the law. Article 10 of the Provisional Regulations on Value-added Tax in People's Republic of China (PRC) stipulates that the input tax of the following items shall not be deducted from the output tax: goods purchased or taxable services used for non-VAT taxable items, VAT-exempt items, collective welfare or personal consumption shall not be deducted. Therefore, the jewelry tax invoice bought in the mall cannot be deducted.
