The start date for the CEST to become mandatory has been extended from 01/10/2016 to 07/01/2016, according to the regulation published on 09.13.2016.
The CEST is a codification that will be used on the standardization and identification of goods and assets included in the Tax replacement scheme (ICMS ST) and on the advance collection of the ICMS in all the Brazilian states.
The company that makes sales of goods included or not in the tax replacement scheme (ICMS ST) has the obligation to inform the CEST code once the electronic invoicing is issued. Otherwise if not done, the SEFAZ validation system will not allow the issuing of the sale invoice. As a result, the company may have problems in its sales operations.
