How the DGT's position has evolved
Current position
The conversion of private elements into common elements constitutes a transfer of real estate subject to ITP/AJD (Transfer Tax/Stamp Duty) or ISD (Gift and Inheritance Tax) depending on the legal instrument used. The modification of horizontal property coefficients is not subject to AJD if it does not alter the value of the land or the construction. The homeowners' association is a taxable person for IVA (VAT) when leasing common elements in the course of an economic activity.
The DGT's position remains constant regarding the distinction between the modification of coefficients and the transfer of elements. It is confirmed that the allocation of private elements to common elements is an onerous or gratuitous transfer subject to taxation. No doctrinal changes are observed, but rather a reiteration of the transfer nature of the allocation of assets.
