How to open a company in Brazil: stages, CNPJ, registration and licenses
Technical guide on the process of opening companies in Brazil via Redesim, covering the choice of legal nature, CNAE, and the impact of regulatory compliance on the initial structuring.
To open a company in Brazil, the entrepreneur must navigate a workflow that integrates the feasibility inquiry, the registration of the constitutive act, the obtaining of the CNPJ, and licensing. This process is mostly centralized by the Rede Nacional para a Simplificação do Registro e da Legalização de Empresas e Negócios (Redesim - National Network for the Simplification of Company and Business Registration and Legalization), although the exact order of the registration steps and system integration vary according to the location and type of economic activity. Initial planning is the pillar for business sustainability, preventing unnecessary costs with reclassifications and fines for non-compliance with the standards of the Departamento Nacional de Registro Empresarial e Integração (DREI - National Department of Business Registration and Integration).
This article is for informational purposes only and does not constitute individualized legal or tax advice. Brazilian legislation is complex and subject to frequent changes; therefore, consulting with qualified professionals is essential before any business decision.

The Business Registration Scenario via Redesim
The formalization process in Brazil is consolidated by digitalization. Redesim integrates federal, state, and municipal bodies to reduce bureaucratic fragmentation. However, the flow between the municipal feasibility inquiry and the generation of the Documento Básico de Entrada (DBE - Basic Entry Document) may present procedural variations between different states. Obtaining the CNPJ (Cadastro Nacional da Pessoa Jurídica - National Registry of Legal Entities) from the Federal Revenue Service occurs in an integrated manner with the registration at the Junta Comercial (Board of Trade) in most cases, but the full activation of the company depends on the completion of specific tax registrations (State and Municipal).
Legal Nature and Company Size
The choice of legal nature (natureza jurídica) determines the liability of the partners and the governance rules. The Sociedade Limitada (LTDA - Limited Liability Company) is a frequent model, allowing the segregation between the personal assets of the partners and the share capital. For the entrepreneur acting without partners, the Sociedade Limitada Unipessoal (SLU - Single-Member Limited Liability Company) offers limited liability protection while maintaining the characteristic of a single holder.
The size of the company (porte) is regulated by Complementary Law No. 123. The classification as Microempresa (ME - Micro Enterprise) or Empresa de Pequeno Porte (EPP - Small Business) is based on annual gross revenue. This classification allows access to the favored treatment provided by law, although enrollment in the Simples Nacional tax regime depends on meeting additional requirements, such as the activity performed and the corporate composition.

Classification of Activities (CNAE) and Corporate Purpose
The CNAE (Classificação Nacional de Atividades Econômicas - National Classification of Economic Activities) classifies the activity and assists in identifying obligations; taxation also depends on effective operations, the regime, and applicable legislation. The corporate purpose (objeto social) must detail the company's activities, serving as the basis for the articles of association. Precision in choosing the CNAE is fundamental to avoid inappropriate taxation. High-risk activities may require prior inspections before the start of operations, depending on the guidelines of the local city hall and regulatory agencies.
Tax Regimes and Normative Transition
The definition of the tax regime — Simples Nacional, Lucro Presumido (Presumed Profit), or Lucro Real (Actual Profit) — directly impacts cash flow. With the enactment of the Tax Reform (Constitutional Amendment 132/2023), the Brazilian system will undergo a transition to the Contribuição sobre Bens e Serviços (CBS - Contribution on Goods and Services) and the Imposto sobre Bens e Serviços (IBS - Tax on Goods and Services).
- Lucro Presumido: Taxation is levied on a profit margin pre-fixed by law. It is a regime that requires regular accounting, albeit simplified compared to Lucro Real.
- Lucro Real: Mandatory status must be verified under legal hypotheses, including total revenue from the previous year above the applicable limit. The accounting base undergoes tax adjustments; operational expenses do not mean automatic deduction.
- Simples Nacional: Unified regime for ME and EPP. During the reform, companies in this regime may have specific rules for the transfer of IBS and CBS credits.
Contrary to simplistic interpretations, the utilization of CBS credits is not an exclusive advantage of Lucro Real, as credit analysis depends on non-cumulativity and the position in the production chain. When evaluating tax regimes, the manager must project the impact of the tax transition.
Practical Steps for Opening
The standard itinerary for opening a company involves:
- Feasibility Inquiry (Consulta de Viabilidade): Prior verification with the city hall regarding the possibility of exercising the activity at the chosen location and the availability of the business name.
- Drafting the Constitutive Act: Preparation of the Articles of Association (Contrato Social) or Bylaws (Estatuto), defining share capital and rules among partners.
- Registration and CNPJ: Filing with the Junta Comercial (Board of Trade) or Cartório (Registry Office) (depending on the legal nature). In the integrated flow indicated by DREI, the completion of the Módulo de Administração Tributária (MAT - Tax Administration Module), after registration, integrates the generation of the CNPJ. Check the local integration and the competent registration body.
- Tax Registrations: Obtaining the Inscrição Municipal (Municipal Registration - for service providers) and Inscrição Estadual (State Registration - for commerce and industry).
Licensing and Permits
Licensing is the operational regularization stage. The risk level of the activity, defined by CGSIM Resolution No. 51, determines whether licensing will be automatic or will require prior inspections. Industrial activities may require environmental licensing, and activities related to health or food may require sanitary licensing, but the requirement for both simultaneously depends on the specificity of the operation and local norms. Although the absence of specific licenses may result in administrative sanctions, the interruption of invoice issuance or immediate closure are not universal automatic consequences, depending on the due municipal administrative process.
Common Errors and Compliance
A frequent error is asset commingling (mixing personal and business accounts), which can compromise limited liability protection. Another critical point is negligence with trademark registration at the INPI (Instituto Nacional da Propriedade Industrial - National Institute of Industrial Property), as the CNPJ, business name, and trademark have distinct functions. The CNPJ does not confer trademark exclusivity; its protection depends on the INPI's own rules. Furthermore, for companies with foreign trade, the planning of Radar Siscomex should be anticipated to avoid cargo delays.

Frequently Asked Questions
Does Simples Nacional end with the tax reform?
No. Simples Nacional is constitutionally maintained. However, there will be transition rules for IBS and CBS. Simples companies may opt to collect these new taxes through the regular (non-simplified) regime to allow their clients to utilize full credits.
Can an SLU have more than one partner?
By definition, the Sociedade Limitada Unipessoal has only one partner. If new partners join the company, the contract must be amended to reflect the plurality of partners; the company remains a limited liability company.
Does Lucro Presumido exempt the company from accounting?
No. Although the calculation of IRPJ (Corporate Income Tax) and CSLL (Social Contribution on Net Profit) is based on a presumed margin, the company must still maintain accounting books for corporate and labor purposes, and for the determination and verification of results and compliance with rules applicable to distributions.
Is the Redesim system mandatory throughout Brazil?
Redesim is the national standard, but its implementation and the level of integration between city halls and states may vary. In some municipalities, specific steps may still require access to their own local portals.
Next Steps
After formal registration, management should focus on maintaining tax and operational regularity.
