Deadline for investment
Regarding the period that the taxpayer has to make the investment, article 37.2 of the RDLeg. 4/2004 establishes that the investment in assets related to economic activities must be made within the period between the beginning of the tax period in which the profits to be invested are obtained and the two subsequent years or, exceptionally, in accordance with a special investment plan approved by the tax authorities at the proposal of the taxpayer.
In this way, in addition to the two-year period, there is the possibility of a special investment period approved by the Tax Administration, taking into account article 37.3 of the RDLeg. 4/2004 establishes that the deduction is applied to the entire amount of the tax period in which the investment is made; for investments subject to longer periods, this deduction could continue to be applied.
