How the DGT's position has evolved
Current position
For spin-offs to qualify for the special regime, the contribution must consist of a business line, defined as an economic unit with an organization of material and human resources that operates by its own means. In proportional total spin-offs, no income is recognized in the transferring entity or in the shareholders if the original values and acquisition dates are maintained. However, the operation must lack tax evasion purposes and comply with commercial regulations.
The DGT's position remains constant regarding the definition of a business line, always requiring an autonomous and differentiated organization. A consolidation of the criterion is observed regarding the need for a functional economic unit to avoid the transfer of isolated elements. Recent doctrine reaffirms tax neutrality in proportional total spin-offs provided that commercial requirements are met.
