How the DGT's position has evolved

Stable position Medium confidence 25 rulings · 2014–2024

Current position

Persons or entities that contract or subcontract works or services related to their main economic activity are subsidiarily liable for the tax obligations that must be passed on or withheld. This liability is limited to the portion corresponding to the works or services subject to the contract or subcontract. Likewise, the obligation to register in the Census of Businessmen (Censo de Empresarios) is established for those carrying out economic activities.

The DGT does not present a doctrinal evolution regarding a single concept, but rather addresses various facets of tax obligations in independent rulings. A constant application of subsidiary liability in subcontracting and the transfer of obligations in successions is observed. There is no change in criterion, but rather a thematic dispersion regarding the fulfillment of formal and material duties.
