According to information from Diário de Notícias, citing a source from the Ministry of Solidarity and Social Security, the new Social Security contribution scheme that will come into force in 2018 provides that those who have opened an activity as holder of category B income, when those incomes are obtained exclusively through the exploitation of local accommodation and / or urban lease, will be exempt from contributing to Social Security, thus not having to discount the single social tax or TSU. The practical effect of this change is expected to occur only in 2019.
