How the DGT's position has evolved
Current position
Income obtained from the transfer of own funds to third parties is classified as income from movable capital included in the savings tax base. In joint account contracts (cuentas en participación), the participant is taxed on the difference between the amount received and the amount contributed, while for the manager, these constitute expenses or business income. Bonuses for customer loyalty are also considered income from the transfer of own funds subject to withholding tax.
The DGT's position remains constant in classifying the income as movable capital. The doctrine has increasingly applied this concept to more diverse types of operations, ranging from the amortization of loans and preferred shares to joint accounts and loyalty bonuses. No changes in criteria are observed, but rather an extension of the application of article 25.2 of the Personal Income Tax Law (LIRPF) to new scenarios.
