Do I Need to Register as an MEI to Sell on Instagram? What to Know Before You Start

You posted your first products, the messages started coming in, and someone paid via Pix. Then the question hits: do I need to register as an MEI to keep selling on Instagram? The short answer is that no law requires you to have a CNPJ (Brazil's business tax ID) to make a one-off sale or receive a Pix payment. But once selling becomes routine, going formal stops being a minor detail. This post explains what an MEI is, who can register, what changes in your day-to-day, and when it's worth calling an accountant.

What an MEI is, in a nutshell

MEI stands for Microempreendedor Individual (Individual Microentrepreneur). It's the simplest way to get a CNPJ in Brazil, designed for self-employed people with low revenue. With it, you exist as a business: you can issue invoices, open a business bank account, sell to other companies, and contribute to the INSS (Brazil's social security system).

Registration is free and done online through the Portal do Empreendedor, using your gov.br account. Be wary of websites that charge to “open your MEI”: they usually just fill out the same form you could fill out yourself for free.

When selling without a CNPJ stops making sense

Selling every now and then, like clearing out clothes you no longer wear or making an order for a friend, is different from running a business. If you sell every week, have a catalog, promote on Instagram, and depend on that income, you're already carrying out a commercial activity. Staying informal in this scenario brings some practical problems:

• You have no social security coverage unless you contribute to the INSS some other way.
• You can't issue invoices, which closes doors with customers that are businesses.
• You mix personal and business money, making it hard to know whether you're actually turning a profit.
• Your income still has to be declared on your personal income tax return, according to the Receita Federal's rules.

In other words, the question isn't just “am I required to?” but “does it make sense for where I am right now?”.

Who can be an MEI

Not everyone qualifies. These are the main criteria:

• Annual revenue cap. There's a limit on gross revenue per year. It's currently R$ 81,000, but this amount can change, so always check the official portal before deciding.
• Permitted activity. Your occupation must be on the list of activities allowed for MEIs. Many common activities for Instagram sellers are on it, such as selling clothes, handicrafts, sweets and savory snacks, cosmetics, and various beauty services.
• Not being a partner or owner of another company.
• Having at most one employee, following the salary rules set for MEIs.

Regulated professions, such as doctors, lawyers, psychologists, dentists, and nutritionists, generally can't be MEIs. If that's your case, the path to going formal is different, and this is where an accountant makes a difference.

If you're a content creator or sell digital products, take a close look at the list: depending on what you sell (courses, mentoring, advertising), there may or may not be a matching occupation. Don't pick a “similar” activity just to fit in.

What changes in practice after you register

Monthly contribution (DAS)

Every month you pay a bill called the DAS. It's a fixed amount that doesn't depend on how much you sold, and it includes your INSS contribution plus a small tax amount based on your activity (trade, services, or both). The amount is updated every year, usually in line with the minimum wage. You generate the bill on the Portal do Empreendedor itself or in the official MEI app.

Paying on time is what guarantees access to INSS benefits, such as retirement by age, disability benefits, and maternity pay, subject to each one's minimum contribution period.

Invoices

This is one of the biggest questions. Under current rules, generally speaking:

• Sold to an individual: MEIs are usually exempt from issuing an invoice, although they can issue one if the customer asks.
• Sold to a business (CNPJ): issuing an invoice is mandatory.

For services, the invoice is issued through the national NFS-e system. For products, the rules may vary by state. When in doubt, check with your city hall, your state's finance department, or Sebrae.

Record-keeping obligations

MEIs have few obligations, but they do exist:

1. Record your revenue every month in a revenue report, keeping your purchase and sales invoices.
2. File the annual declaration (DASN-SIMEI), stating how much you earned the previous year.
3. Keep an eye on the revenue cap so you don't lose MEI status without noticing.

Business bank account

There's no legal requirement to have a business account, but separating your business money from your personal money is one of the most useful decisions you can make. With a CNPJ, you can open a business account and register a Pix key in the company's name, which also gives buyers more confidence.

Common mistakes when registering as an MEI on impulse

• Choosing the wrong activity. This can cause problems when issuing invoices or when trying to change it later.
• Forgetting the DAS. The debt piles up with interest and you can lose access to benefits.
• Not tracking your revenue. Going over the cap without noticing can lead to retroactive charges.
• Thinking the MEI solves everything. It simplifies things, but it doesn't replace financial organization.

Next steps to help you decide

1. Add up how much you sell per month and project it for the year.
2. Check whether your activity is on the list on the Portal do Empreendedor.
3. See whether you already have another company or a tie that would prevent you from qualifying.
4. Read the updated rules on the official portal and, if you'd like free guidance, reach out to Sebrae or your city's Sala do Empreendedor.
5. Register through gov.br once you're confident in your choice.

When it's worth finding an accountant

For many people, the MEI is something you can handle on your own. But it's worth talking to an accountant if:

• Your revenue is close to the cap or likely to exceed it soon.
• Your activity isn't on the list or you're not sure which one to choose.
• You're in a regulated profession.
• You sell digital products, do advertising, or have several types of income.
• You plan to hire or to sell to businesses frequently.

Going formal isn't about red tape. It's about having a business that can grow without nasty surprises.

Organize your sales from the start

With or without a CNPJ, Instagram sellers gain a lot when they stop handling everything through DMs. With Keepo, you build a link-in-bio page with your catalog, forms, scheduling, and Pix and card payments, all in one place. That makes it easier to track what's coming in and make decisions, including whether to go formal. Create your Keepo and get your business ready for the next step.
