How the DGT's position has evolved

Refined position High confidence 8 rulings · 2015–2026

Current position

For the reinvestment exemption, both the transferred and the acquired property must be the habitual residence. A commercial premises may be considered a habitual residence if it is adapted or capable of being adapted as a residence and is effectively and permanently inhabited, regardless of its registry classification or urban planning regulations. Renovation works only count as a reinvested amount if they qualify as rehabilitation, reconstructing structures, facades, or roofs and exceeding 25% of the building's value.

The DGT's position has evolved from the technical definition of commercial premises for the IAE (Business Activity Tax) towards the application of the concept of habitual residence within the scope of the reinvestment exemption. In this latter area, the doctrine has consolidated, allowing adapted commercial premises to be considered a habitual residence. Likewise, the requirements for renovation works to count as reinvestment have been specified.

Turning points

  1. V3105-23

  2. V1396-26

    Clarifies that both the transferred and the acquired property must be the habitual residence and reinforces that the concept of habitual residence prevails over registry or urban planning classification.
