In a statement, the local authority said that similar to what is already done in other neighbouring municipalities, Oeiras will start charging a tourist tax, under the scope of the Regulation of Administrative Permissions, Taxes and Other Revenues (RAPTOR) of the municipality, approved in the municipal assembly and published in the Official Gazette.

The tax will be applied to paid overnight stays in hotels and local accommodation establishments in the municipality of Oeiras, in the district of Lisbon.

The council states that the tax is intended to "ensure a counterpart for the enjoyment of a set of activities and investments promoted by the municipality of Oeiras, related to tourism", namely the safeguarding of traditional commerce, creation of cultural and recreational hubs, management of public spaces, provision of municipal information and support services for tourists, surveillance, security and civil protection in the municipality.
