Simples Nacional deadlines extended for 2027 tax regime options

The Simples Nacional Management Committee (CGSN) has extended deadlines for micro and small enterprises to make critical tax decisions regarding the 2027 fiscal year. This extension follows reports of operational difficulties and system errors encountered by accountants and businesses.

Key deadlines include October 15, 2026, for requesting entry or return to the Simples Nacional regime for 2027, and October 30, 2026, for companies choosing whether to collect the new IBS and CBS taxes through the regular regime or within the Simples system. Additionally, October 30 serves as the deadline for regularizing pending issues that may have caused initial denials of Simples Nacional applications.

The changes are part of the transition to Brazil's tax reform. While Microentrepreneurs (MEI) do not need to make a specific choice for the new taxes, they are advised to monitor how their business-to-business transactions may be affected by the ability of clients to claim tax credits under the new IBS and CBS rules.
