Article 5 clarifies the relationship between the deemed legal person created under Article 4 and the individual liability of the partners. It stipulates that a tax assessment made on the income of the partnership does not prejudice or diminish the personal liability of each party to the agreement for any tax due and payable by them. This ensures that while the partnership is assessed as a unit, the underlying partners remain legally responsible for fulfilling tax obligations, providing the Tax Authority with recourse against both the entity and its participants.
