How the DGT's position has evolved

Settled doctrine High confidence 29 rulings · 2014–2024

Current position

The tax treatment of a service depends on its relationship of ancillarity to the principal supply. If a service is eminently ancillary to an exempt activity or one with a reduced rate, it shares the treatment of the principal supply. If they are provided independently or are not ancillary for the recipient, they are taxed according to their own nature.

The DGT maintains a constant position on ancillarity. Through rulings, it is confirmed that the nature of the principal service determines the treatment of ancillary elements, provided that these do not constitute an end in themselves for the client. No changes in criterion are observed, but rather the application of the rule to different sectors.
