Is it a non-public welfare donation to poor areas through company C?

No, there is a list of organizations that meet the pre-tax deduction conditions for charitable donations, and pre-tax deduction can only be made through group donations on the list.

Article 9 of the current enterprise income tax law stipulates: "The public welfare donation expenses incurred by an enterprise within 12% of the total annual profit are allowed to be deducted when calculating the taxable income." The total annual profit refers to the amount greater than zero calculated by the enterprise according to the unified accounting system of the state. The proceeds will be donated to the poor.
