Article 13
1. States, regional and local government authorities and other bodies governed by public law shall not be regarded as taxable persons in respect of the activities or transactions in which they engage as public authorities, even where they collect dues, fees, contributions or payments in connection with those activities or transactions. However, when they engage in such activities or transactions, they shall be regarded as taxable persons in respect of those activities or transactions where their treatment as non-taxable persons would lead to significant distortions of competition. In any event, bodies governed by public law shall be regarded as taxable persons in respect of the activities listed in Annex I, provided that those activities are not carried out on such a small scale as to be negligible. 2. Member States may regard activities, exempt under Articles 132, 135, 136, 371, 374 to 377, and Article 378(2), Article 379(2), or Articles 380 to 390, engaged in by bodies governed by public law as activities in which those bodies engage as public authorities.
