## Overview of Simples Nacional Changes Under the New Tax Reform
Brazil’s tax reform of consumption—anchored in **Emenda Constitucional nº 132/2023**—introduces the **IBS** (Imposto sobre Bens e Serviços) and **CBS** (Contribuição sobre Bens e Serviços), replacing existing PIS, Cofins, ICMS, ISS and IPI over time. These changes affect all business entities, including those under Simples Nacional (ME and EPP).

### What’s specifically changing for ME/EPP?
- The **Nota Fiscal de Serviços Eletrônica (NFS-e)** becomes mandatory nationally for ME’s and EPP’s starting **1 November 2026**. ([gov.br](https://www.gov.br/receitafederal/pt-br/assuntos/noticias/2026?utm_source=openai))
- As of **1 January 2027**, IBS/CBS rules under Simples Nacional begin to produce **tax effects**. That includes the obligation to highlight CBS/IBS in documents and transitions of current contributions. ([gov.br](https://www.gov.br/receitafederal/pt-br/assuntos/noticias/2026?utm_source=openai))
## Actionable Steps for ME/EPP’s Before 2027
| Timeframe | Key Tasks | Reason/Benefit |
|---|---|---|
| **Now–Oct 2026** | Review current issuance of NFS-e and ensure your software or provider can emit the national NFS-e. | Avoid penalties or rejections when the requirement becomes enforceable. |
| **Aug-Nov 2026** | Update documentation workflows to include CBS and IBS when layout and obligations are clarified. | Ensures compliance from 1 Jan 2027 when tax effects kick in. |
| **1 Jan 2027** | Use updated invoices with CBS/IBS, and for persons previously using simpler tax bases, follow new rules. | Proper input of taxes allowed, avoids legal risk. |
## Practical Example: Small Restaurant (EPP)
- Before Nov 2026: emits local NFS-e without IBS/CBS breakdown; serves a café in town.
- From Nov 2026: must switch to national NFS-e format and ensure the system is ready.
- From Jan 2027: invoices must clearly show CBS and IBS components—even if tax calculation still under Simples National formula—for future audits or compliance checks.
## Tips and Pain-Points to Watch Out For
- **Software Compatibility**: Your billing/invoice software must support the changes—upgrade early.
- **Education & Training**: Ensure your accounting staff or service providers understand new layout, new tax bases, and will meet deadlines.
- **Cash Flow Projections**: Tax burden perception might change with CBS/IBS even if actual payments are deferred—so budget accordingly.
- **Legal & Contractual Documents**: Contracts needing invoices should be reviewed; payment terms sometimes linked to tax documents.
**Bottom Line**: While major tax payments under Simples Nacional won’t immediately change until 2027, the reforms bring mandatory tools (e-invoices, new tax items) and technical obligations starting now. Get your business ready.
