Find Out Which Professions Cannot Be MEI, Understand the Reasons, and Know Legal Alternatives to Formalize Your Work Safely and Regularly.
Many Brazilians see the Individual Microentrepreneur (MEI) as a gateway to formalize their own business, issue invoices, and access social security benefits.
However, not all activities can be registered under this simplified model.
Professionals who perform certain functions need to seek other types of business formalization, as they do not meet MEI criteria.

What is MEI and Who Can Formalize?
MEI was created to formalize self-employed workers and small entrepreneurs, allowing them to have a CNPJ, social security rights, and tax simplification.
To qualify, the professional needs to have a limited annual revenue and engage in an activity listed as permitted.
If not, registration as a MEI is not possible.
Professions That Cannot Be MEI
Some professions, even if self-employed, cannot formalize as MEI.
These professionals must resort to other business models, such as limited liability companies or individual entrepreneurs, which provide an adequate structure for their activities.
Why Some Professions Cannot Be
The restriction exists because certain activities require technical responsibility, higher revenue, or specific regulation.
MEI was designed for less complex activities that do not require registration with professional councils or high technical specialization.
Thus, professionals working in health, law, engineering, and accounting cannot fit into this model.
Regulated Professions That Cannot Be MEI
Some professions require registration with professional councils and, therefore, cannot be formalized as MEI.
Among these activities are:
- Administrator: requires registration with the Regional Administration Council (CRA).
- Lawyer: requires registration with the Brazilian Bar Association (OAB).
- Architect: requires registration with the Council of Architecture and Urbanism (CAU).
- Accountant: requires registration with the Regional Accounting Council (CRC).
- Dentist: requires registration with the Regional Dentistry Council (CRO).
- Economist: requires registration with the Regional Economics Council (CORECON).
- Engineer: requires registration with the Regional Council of Engineering and Agronomy (CREA).
- Journalist: requires registration with the Ministry of Labor and Employment (MTE).
- Doctor: requires registration with the Regional Medical Council (CRM).
- Psychologist: requires registration with the Regional Psychology Council (CRP).
- Advertiser: requires registration with the Regional Advertising Council (CONAR).
- Translator: requires registration with the Commercial Board or specific entities.
- Veterinarian: requires registration with the Regional Council of Veterinary Medicine (CRMV).
Professions with Higher Complexity or Risk
In addition to regulated activities, there are other professions that, due to their complexity or risk involved, cannot be formalized as MEI.
Examples include:
- Financial Consultant: requires greater technical responsibility and often registration with regulatory bodies.
- Software Developer: activities that involve intellectual property and complex contracts.
- Physiotherapist: requires registration with the Regional Council of Physiotherapy and Occupational Therapy (CREFITO).
- Nutritionist: requires registration with the Regional Council of Nutritionists (CRN).
- Teacher: educational activities that require registration with competent bodies and compliance with specific regulations.
Alternatives for Those Who Cannot Be MEI
Those who do not qualify as MEI can still formalize through other business regimes.
Opening a Sole Proprietorship (EI), Individual Limited Liability Company (EIRELI), or Limited Liability Company (LTDA) are viable alternatives.
These modalities allow the professional to issue invoices and benefit from specific tax regimes, even without the simplified classification of MEI.
Knowing which professions cannot be MEI is essential to avoid legal issues and ensure correct fiscal classification.
Professionals who do not fit into MEI should evaluate other forms of formalization to operate legally and take advantage of benefits like issuing invoices and social security protection.
