How the DGT's position has evolved
Current position
The licensing of software together with installation or configuration services is considered a single provision of services. In the context of international treaties, payments for the use of programs may be classified as royalties, although their taxation in Spain depends on the existence of a permanent establishment. The distinction between standard and customized software is a matter of fact that determines the classification of the income.
The DGT's position is heterogeneous because the rulings address different aspects: VAT (IVA), Corporate Income Tax (IS), and international treaties. There is no single doctrinal evolution, but rather an application of specific criteria for each case, such as the accessibility of services or the classification of royalties according to the applicable treaty.
