On 3 May 2017 the European Parliament adopted a resolution on the need to address regulatory grey areas that cause significant differences among member states due to national and local regulations and case law. These new business models range from providing accommodation (e.g. Airbnb) and car journeys (e.g. Uber), to domestic services. The recommendations include, amongst others, (i) individual v professional providers: effective criteria for distinguishing between “peers” (e.g. individual citizens providing services on an occasional basis) and “professionals” is needed, with general principles at EU level and thresholds at national level; (ii) consumer rights: information to consumers about the rules applicable to each transaction and their rights; (iii) liability; the EU Commission should further clarify the collaborative platforms’ liability as quickly as possible; (iv) workers' rights: fair working conditions and adequate protection should be guaranteed for all workers in the collaborative economy; and (v) taxation: similar tax obligations should be applied to businesses providing comparable services, whether in the traditional economy or in the collaborative economy; MEPs advocate innovative solutions for improving tax compliance and call on platforms to collaborate to this end.
