How the DGT's position has evolved
Current position
For the deduction of passenger vehicle expenses, assignment to the economic activity is only permitted if the use for private needs is ancillary and notoriously irrelevant. In the case of the exemption for reinvestment in the primary residence, the residence must be continued for at least three years with effective and permanent use. If there is a partial lease of the dwelling, the exemption is limited proportionally to the part used privately, including common areas.
The DGT's position on the deductibility of vehicles has moved from requiring exclusive assignment without private use (V0736-20) to allowing the deduction if the private use is ancillary and notoriously irrelevant (V2163-22). Regarding housing, it has been specified that the primary residence requires effective and permanent use for at least three years (V2115-24). The remaining rulings regarding tourist registration and vessels maintain consistent criteria regarding the non-performance of lucrative activities.
Turning points
-
Allows the deduction of passenger vehicle expenses as long as the private use is ancillary and notoriously irrelevant, relaxing the previous requirement of exclusive assignment.
-
Establishes that the primary residence requires continued residence for at least three years and limits the reinvestment exemption if the dwelling is partially leased.
