How the DGT's position has evolved
Current position
Assignments with retention of title are considered supplies of goods subject to IVA (Value Added Tax). In the scope of IRPF (Personal Income Tax) and Wealth Tax, the acquirer counts the amounts paid as a right and has no obligation to report the property on Form 720 until they acquire ownership under common law. If possession is not transferred, the income is not accrued upon formalization, but rather when the full agreed price is paid.
The DGT's position remains stable regarding the nature of the transaction as a supply subject to IVA. The evolution is observed in the technical precision regarding the timing of income accrual and the classification of amounts received, which are not considered income but rather a liability until full payment is made if possession is not transferred.
Turning points
-
Clarifies that assignments with a retention of title clause are supplies of goods subject to IVA and establishes that the resolution of a previous transfer does not affect the classification of the current supply.
-
Specifies that if possession is not transferred, the income is not accrued upon formalization but upon full payment of the price, and previous amounts must be considered a liability.
