How the DGT's position has evolved
Current position
For a civil society to be a taxpayer for Corporate Income Tax (IS), it must possess fiscal legal personality and a commercial purpose. A commercial purpose requires performing production, exchange, or service activities in a non-excluded sector. Fishing activity is considered outside the commercial scope, which prevents civil societies dedicated exclusively to it from being taxed under this tax.
The DGT's position remains constant throughout the analyzed sequence. Since 2015, the Administration has maintained that fishing activity is excluded from the commercial scope, preventing the fulfillment of the requirements necessary for civil societies to be taxed under Corporate Income Tax (IS).
