The generally accepted definition of SMEs in Chile is based on the annual turnover criterion set forth by Law 20 4161 that establishes special rules for SMEs. The number of employees is not taken into account in the definition.
In Chile, SMEs account for the majority of the total number of enterprises. In 2014, 98.5% of firms were classified as SMEs, including employer and non-employer firms in all industries. Micro-enterprises made up 75% of the total number of firms, whereas small and medium-sized businesses accounted for 20.7% and 3.1%, respectively. Although SMEs represent almost all of the enterprises, they only account for about 16% of the total amount of annual sales. According to the statistics of the Internal Revenue Service (Servicio de Impuestos Internos, SII) SMEs accounted for 45% of the payroll of Chilean firms in the commercial year 2014.
