Under Article 9, the net income or loss of a taxable entity for a tax period is determined from its financial statement income, subject to specific adjustments. The law mandates the exclusion of several income types to arrive at the correct tax base. These exclusions specifically cover income from dividends or share distributions, gains or losses on equity holdings, including capital gains from shares, and any revenues resulting from the waiver of the entity's debts. Furthermore, income derived from international marine transportation and shipping activities must also be excluded. The executive regulations are designated to specify the detailed rules, conditions, and controls for implementation.
