How the DGT's position has evolved
Current position
The deduction for investment in new or recently created companies requires that the holdings remain in the equity for a period exceeding three years. If this period is not met, the taxpayer must add to the state net tax liability the totality of the unduly applied deductions plus late payment interest. In the event of a partial sale, the regularization is applied proportionally to the part of the investment sold.
The DGT's position remains constant regarding the obligation to regularize the state net tax liability upon failure to meet the holding period. The 2020 and 2021 rulings confirm the need to add the deductions and late payment interest. The 2023 ruling specifies that, in the event of a partial sale, the regularization must be proportional.
