How the DGT's position has evolved
Current position
Transactions between related entities must be valued at their market value, understood as the value agreed upon by independent parties under free competition conditions. In the case of intra-group services, these must produce or be capable of producing an advantage or benefit to their recipient. For services provided by a partner to their company to be taxed as economic activities, the company must be engaged in professional services and the partner must be registered in the special regime for self-employed workers.
The DGT's position remains constant regarding the valuation of related-party transactions through the arm's length principle. A specialization is observed in the classification of the nature of partner returns, distinguishing between income from employment and from economic activities according to the corporate purpose and the social security regime. No changes have been observed in the market valuation doctrine since 2015.
