How the DGT's position has evolved
Current position
The classification of income depends on the nature of the activity and the assumption of risk. Intermediation is classified as an economic activity if risk and venture are assumed, or as professional if they are not. Services provided by partners to companies are considered employment income unless they meet the requirements of an economic activity in the IAE and registration with Social Security. The assignment of intellectual property rights is employment income unless there is a prior professional activity with the organization of means.
The DGT maintains a clear distinction between employment income and income from economic activities based on the structure of the activity. A tendency is observed to require the concurrence of specific requirements, such as the organization of production means or registration with Social Security, to avoid classification as employment income. The position on intellectual property has shown nuances depending on the author's prior activity.
