Brazil Tax Reform: Split Payment and Electronic Document Implementation

Brazil's tax reform is entering critical implementation phases, introducing the 'split payment' mechanism and new electronic documentation requirements. The split payment system, designed to automate the collection of the Imposto sobre Bens e Serviços (IBS) and Contribuição sobre Bens e Serviços (CBS), will be optional and limited in scope during its 2027 rollout. Micro-enterprises remaining entirely within the Simples Nacional regime and transactions with individual consumers will be excluded from the system in its first year.

In parallel, the implementation of electronic fiscal documents (NF-e, NFC-e, and CT-e) linked to the new taxes is scheduled for 2026. To facilitate the transition, the Receita Federal and the IBS Management Committee have announced a temporary flexibility in validation rules, allowing documents to be accepted even without specific IBS and CBS fields during the adjustment period.

Despite these measures, businesses face significant operational challenges. A study by NTT DATA involving over 1,000 organizations revealed that 41% of companies still express doubts regarding the migration to the new model, citing concerns over internal process changes and the risk of calculation errors.
