Where the total procurement cost of equipment or technology for pollution control purchased by a private institution participating in a transportation infrastructure project for self-use in the same taxable year exceeds NT$600,000, a portion of such procurement cost as calculated according to the following percentages may be credited against its profit-seeking enterprise income tax payable for the current year. Where the amount of profit-seeking enterprise income tax payable for the current year is less than the creditable amount, the balance of such creditable amount may be credited against profit-seeking enterprise income tax payable in the ensuing four years.
