How the DGT's position has evolved
Current position
The deduction for investment in newly created or recently established companies is applied in the tax period in which the amounts for subscription are disbursed. For a capital increase to be valid, it requires a General Meeting agreement, a public deed, and registration in the Mercantile Registry. In the case of the acquisition of real estate, these must be real estate investments used for the economic activity. If the investment is made jointly with a spouse, the deduction is limited to each person's ownership percentage.
The DGT's position remains constant in the application of the requirements of article 68.1 of the LIRPF (Personal Income Tax Law), addressing different technical aspects such as legal form, the limit of equity, or the reinvestment of gains. No change in doctrine is observed, but rather an application of specific criteria for different scenarios (companies, reinvestment, real estate, or capital increases). The evolution is a technical and fragmented application of the current regulation.
Turning points
