How the DGT's position has evolved
Current position
The Tax Administration maintains the power to apply the institutions of simulation or conflict when economic facts deviate from reality to obtain a tax benefit. In the scope of objective estimation, operations of companies where the taxpayer is a shareholder or administrator do not count towards the personal activity limit. However, it is monitored that the structure is not used with the exclusive purpose of reducing the tax burden.
The DGT's position remains constant in the defense of economic reality against artificiality. Throughout the rulings, it is reiterated that the Administration is competent to declare simulation when tax planning is used for the exclusive purpose of reducing the tax burden. No changes in criterion are observed, but rather a recurring application of these institutions in various areas such as pension plans or objective estimation.
