In Portuguese Social Contribution on Net Profits is named Contribuição Social sobre o Lucro Líquido and often referred to by the abbreviation CSLL.
CSLL is one of the contributions that finance the Brazilian social security system and every resident company in the country is subjected to the payment of this tax.
CSLL can be levied on net profit at two different rates: 12% for financial institutions and 9% for other institutions. However, if the contribution is levied on a presumed profit then the calculation should be based on the following values:
12% of the gross revenue to commercial and industrial activities as well as hospital and transportation services
32% of the gross revenue for general services
