How the DGT's position has evolved
Current position
Investment companies, as collective investment institutions, are exempt from the duty to issue invoices. If the company only carries out operations exempt from IVA (Value Added Tax) or for which no invoice must be issued, it has no obligation to submit the annual RGAT declaration. In mergers, the tax neutrality regime may be applied if the requirements of article 76.1 of the LIS (Corporate Income Tax Law) are met and fraud is not the primary objective.
The DGT's position remains stable regarding the application of the special merger regime for IIC (Collective Investment Institutions), provided that valid economic reasons exist. No doctrinal change is observed, but rather a constant application of the regulations on tax neutrality and formal obligations. Recent rulings maintain consistency with the criteria established in 2015 and 2016.
Turning points
-
Specifies that reasons such as customer acquisition, cost savings, and economies of scale constitute valid economic reasons for the merger.
-
Confirms the exception to the duty to issue invoices for investment companies and the consequent exemption from the annual RGAT declaration if they only carry out such operations.
