Article 38 specifies the rules for determining the cost base of a partner's share within a partnership. The initial base is established by the amount the partner pays for their share, plus the cost base of any property they contribute. This base increases with the partner's allocated share of partnership income, including exempt income, and their portion of partnership debt. Conversely, the cost base decreases, without falling below zero, by distributions from the partnership, the partner's share of losses, and non-deductible expenses. Debt incurred personally by partners only increases the cost base for those specific partners.
