How the DGT's position has evolved
Current position
Temporary Business Unions (UTE) are taxpayers for Corporate Income Tax (IS) if they meet the requirements of Law 18/1982. Regarding the Business Activity Tax (IAE), they must be registered under the headings corresponding to the activities they effectively carry out, applying group 508 without a fee for construction activities. Regarding Value Added Tax (IVA), transport services provided by the members to the UTE are taxable and not exempt.
The DGT's position remains stable and is dispersed across different tax matters. No doctrinal change is observed, but rather an application of specific criteria for each tax: Corporate Income Tax (IS), Business Activity Tax (IAE), and Value Added Tax (IVA). Recent rulings simply clarify the application of regulations in specific activities such as construction or transport.
