How the DGT's position has evolved
Current position
In the direct estimation method, the tax base is determined by adjusting the accounting result according to the rules of the Commercial Code and the applicable tax regulations. In transfers between non-related parties, the income must be included in the tax base in accordance with the accounting result, applying the relevant tax adjustments. The market value rule does not apply if there is no relationship pursuant to article 18.2 of the Law on Corporate Income Tax (LIS).
The DGT's position remains constant in the application of the direct estimation method, where the tax base arises from the adjustment of the accounting result. The analyzed rulings do not show doctrinal changes, but rather apply this principle to different scenarios such as joint venture agreements or asset transfers. The doctrine remains stable regarding the link between accounting and taxation.
