If this posting behavior belongs to the business affiliated with or conducted in the name of your company, then this 650,000 yuan should be obtained as a cost, and the enterprise income tax should be calculated and paid according to the "income-cost-expense-loss" included in the total taxable income of the company. If the legal cost invoice or other original documents are not obtained, all 650,000 yuan can only be included in the taxable income to calculate and pay enterprise income tax.
If the posting business has nothing to do with your company, then your invoicing behavior belongs to falsely issuing special VAT invoices. If the tax amount exceeds 6,543,800 yuan+0,000 yuan, criminal responsibility shall be investigated; if the tax amount exceeds 50,000 yuan, criminal responsibility shall definitely be investigated and a fine of 50,000 yuan to 500,000 yuan shall be imposed.
Be careful when posting.
