You’ve decided to start your own business, you’re excited about the idea of working for yourself, and then you face a doubt that holds many people back at the start: should I open an MEI or a microenterprise? The acronym MEI (Microempreendedor Individual) may seem similar to microenterprise (ME), but the differences between the two formats are significant — and choosing the wrong model can cost you time, money, and headaches.
In Brazil, the formalization of small entrepreneurs has undergone major advances in recent decades. Since the creation of MEI in 2008, by Complementary Law No. 128, millions of Brazilians have left informality and gained access to benefits such as retirement, sick leave, and invoice issuance. In 2026, the country has tens of millions of registered MEIs, making this category the most popular formalization form in the country. Still, MEI is not for everyone.
If you’re starting a business, increasing your revenue, or thinking about hiring employees, understanding the practical differences between MEI and microenterprise is the first step to making a smart decision. In this article, we’ll compare the two formats in detail, so you can choose what makes the most sense for your situation.
What is an MEI?
The Individual Microentrepreneur (MEI) is a legal category created to formalize autonomous workers and small businesses with simple operations. To qualify as an MEI in 2026, you must meet some basic criteria:
- Annual revenue of up to R$ 81,000 (or R$ 6,750 per month, on average)
- Practice one of the activities allowed on the official government list
- Not be a partner, owner, or administrator of another company
- Have at most one hired employee
The MEI pays a fixed monthly contribution, called DAS (Simples Nacional Collection Document), whose value varies according to the activity: there’s a portion for INSS and another for ISS (Service Tax) or ICMS (Tax on Goods and Services Circulation), depending on the sector. The opening process is free, done through the Entrepreneur Portal, and does not require a mandatory accountant.
Among the benefits of MEI are: access to retirement by age or disability, sick leave, maternity pay, invoice issuance, and easy credit access at banks.
What is a microenterprise (ME)?
The microenterprise (ME) is another legal size provided for in Brazilian legislation, defined by Complementary Law No. 123/2006 (General Law for Micro and Small Enterprises). It generally falls under the Simples Nacional regime, but can also opt for Presumed Income or Actual Income.
The main criteria to be an ME are:
- Annual revenue of up to R$ 360,000
- Can have more than one partner
- No fixed employee limit, although the size serves as a reference for classification
- Can pursue a much broader range of activities, including some prohibited to MEI
- Requires formal CNPJ, operating permit, and registration with the business registry office or notary
The microenterprise is required to have an accountant responsible for accounting and tax filings. This represents a monthly cost that must be considered in financial planning.
Key differences between MEI and ME
To make the comparison easier, see the central points side by side:
| Criterion | MEI | Microenterprise (ME) |
|---|---|---|
| Maximum annual revenue | R$ 81,000 | R$ 360,000 |
| Number of partners | Only 1 (owner) | Can have partners |
| Employees | Up to 1 | No fixed limit set by law |
| Mandatory accountant | No | Yes |
| Fixed monthly cost | DAS (reduced amount) | Variable taxes + accounting fees |
| Allowed activities | Restricted list | Broader range |
| Opening | Free and online | Paid, via business registry or notary |
It’s important to note that if the MEI exceeds the annual revenue limit, it is automatically deactivated and must migrate to another category, such as ME. This requires attention throughout the year to avoid being caught by surprise.
When is MEI the best choice?
MEI is ideal for those starting small, operating individually, and with modest revenue. Professionals such as hairdressers, electricians, photographers, freelance designers, seamstresses, app drivers, and artisans typically fit very well in this format.
Other good indicators that MEI is the right option for you:
- You work alone or with, at most, one helper
- Your monthly revenue doesn’t regularly exceed R$ 6,750
- You want to formalize quickly, cheaply, and without bureaucracy
- Your activity is on the list of occupations allowed by MEI
- You don’t plan to have partners in the business
For those taking their first steps, MEI offers an accessible gateway to formalization without the weight of high fixed costs. It’s also worth planning growth from the start — a good simple business plan can help you map out the right time to migrate to another format.
When does microenterprise (ME) make more sense?
ME is more suitable for those who already have a growing business, project higher revenue, or need a more robust legal structure. Consider opening an ME if:
- Your monthly revenue exceeds or is close to R$ 6,750
- You want or need partners in the business
- Your activity is not on the MEI list (such as some regulated professions)
- You need to hire more than one employee
- Your business model requires greater legal credibility with suppliers or corporate clients
Businesses that serve other companies (B2B), need to participate in public bidding, or deal with larger contracts frequently benefit from the more formal structure of ME, even if it implies higher maintenance costs.
Real costs: what each model means for your wallet
This is a decisive point for many people. MEI has a low fixed monthly cost — in 2026, the MEI DAS ranges from approximately R$ 70 to R$ 80 per month, depending on the activity (commerce, services, or both). There’s no obligation to hire an accountant, although it’s advisable to seek professional guidance occasionally.
The microenterprise, on the other hand, has more variable and generally higher costs:
- Opening: business registry fees, municipal permit, and possibly agent or accountant fees
- Monthly accounting fees: can vary greatly, but usually range from R$ 150 to R$ 500 or more, depending on complexity and region
- Taxes: calculated on actual revenue, within Simples Nacional brackets or another chosen tax regime
For those with low revenue, these fixed ME costs can jeopardize business viability. On the other hand, for those earning above the MEI ceiling, ME becomes not only more advantageous but mandatory.
How to migrate from MEI to microenterprise
If you’re an MEI and realized your business has grown — or is growing — to the point of requiring migration, the process is possible and doesn’t need to be traumatic. See the basic steps:
- Hire an accountant: from ME onwards, the presence of an accounting professional is mandatory and strategic
- Complete MEI deactivation: the accountant can do this with the Federal Revenue Service
- Register the company: with the Business Registry Office of your state or with the notary office for registration of legal entities, depending on the corporate type
- Obtain the new company’s CNPJ: issued automatically after registration
- Request municipal permits and licenses: varies according to activity and municipality
- Choose the tax regime: Simples Nacional is the most common for MEs, but the accountant will guide you on the best option for your case
It’s possible to keep the same CNPJ in some cases, but guidance from an accounting professional is essential to ensure the transition is made within the law.
Conclusion: the right choice depends on your moment
There’s no universal answer about which format is “better”. MEI is a brilliant solution for those who want to leave informality with minimal bureaucracy and cost, as long as the business fits within the established limits. Microenterprise, on the other hand, offers more room to grow, hire, have partners, and operate in activities that MEI doesn’t cover — but it requires more structure and investment.
The key point is honesty about your own moment: if you earn little and work alone, MEI is probably sufficient. If you already see you’re “busting” the limits or plan to grow consistently, starting as an ME — or migrating to it — is the most sustainable path.
In either case, formalizing the business is always better than remaining informal. Those with a CNPJ have access to credit, can issue invoices, grow with greater legal security, and protect their personal assets. Whether MEI or ME, the most important thing is to take the first step.
