How the DGT's position has evolved
Current position
Under the transitional regime of the 18th Additional Provision of the Law on Personal Income Tax (LIRPF), it is possible to restart the deduction for investment in the primary residence if the property once again constitutes the taxpayer's habitual residence. To this end, the amounts paid since the property regains said status must be considered. It is necessary to have acquired the home before 2013 and to have applied the deduction in a period prior to that date.
The DGT's position remains constant throughout the sequence. The criterion establishes that restarting the deduction under the transitional regime requires that the home becomes the habitual residence again and that the requirements for acquisition and prior application of the deduction are met. No changes in the interpretation of the rule are observed over the years.
