MEI is free, takes 10 minutes and generates CNPJ on the spot

Many people postpone formalization because they imagine that opening a CNPJ is bureaucratic, expensive and time-consuming. For MEI, it's not. The process is 100% online, free and the CNPJ is generated instantly.

You don't need an accountant, you don't pay any fees, and you can do everything on your phone.

What you need to have before you start

  • CPF regularized in the Federal Revenue Service (see cpf.receita.fazenda.gov.br)
  • Account on GOV.BR (silver or gold level for biometric authentication) — you can create during the process
  • Business address — this could be your home
  • Email and mobile phone for registration
  • Choice of main activity (CNAE) — see table below
  • CNAE codes for common activities

    Complete step-by-step

    1. Go to gov.br/mei

    The official website of the Entrepreneur Portal. Never use third-party websites — opening is always free by the government.

    2. Click on “I want to be MEI”

    You will be directed to the FORMALIZE system.

    3. Log in with the GOV.BR ACCOUNT

    Use CPF + password, or authenticate with biometrics (silver/gold level) or SMS code. If you don't have a GOV.BR account, create it right there — it takes 5 minutes.

    Fill in Personal Data

    Full name, date of birth, voter's card or receipt number of the last income tax return.

    5. Choose activity (CNAE)

    Search for your activity by name or code. You can have up to one main activity and some secondary ones (as long as they are all allowed in Mei).

    6. Enter business address

    It could be the home address. No commercial room required. In some municipalities with restrictive zoning, some activities may have limitations — check with the local city hall if you are in doubt.

    7. Check the data and confirm

    Review everything. After confirming, the system generates the CNPJ instantly.

    8. Download CCMEI

    The Certificate of the Condition of Individual Microentrepreneur (CCMEI) is the document that proves the opening. Save in PDF — you will need to open PJ bank account and to issue invoice.

    Common errors when opening MEI

  • Choose wrong CNAE — choose the activity that describes exactly what you do. Wrong CNAE can cause problems in the issuance of invoices.
  • Use address in restricted condominium — some condominiums prohibit commercial activity in apartments. Check the convention.
  • Do not pay DAS in the first month — the first DAS is due on the 20th of the month following the opening. Delay generates interest and a fine.
  • Forget the annual DASN — by May 31 of each year, you need to declare the previous year's billing. Fine of R$ 50-1,000 for those who do not declare.
  • Do not issue invoices to PJ customers — it is mandatory. Making payments without an invoice creates risk for the customer and for you.
  • Digital banks for MEI (zero annuity or low cost)

    Frequently asked questions

    Is it mandatory to have a bank account for MEI?

    There is no separate bank account legal obligation, but it is highly recommended. Mixing personal and legal accounts makes it difficult to control finances and declare income tax. Opening a PJ account at the aforementioned digital banks is free of charge.

    Can I have MEI with a dirty name (CPF negative)?

    Yes. The default in the CPF does not prevent the opening of the MEI. The process in gov.br does not consult SPC/Serasa. The restriction may appear when trying to open a bank account — digital banks tend to be less strict.

    Does the MEI become active if it does not pay THE DAS?

    The CNPJ is active, but you accumulate debts with the Federal Revenue Service. Overdue debts generate interest (SELIC) + a fine of 0.33% per day. If you are late for too long, you may have the MEI compulsorily canceled.

    Can I have more than one CNAE in MEI?

    Yes, it is possible to have one main activity and secondary activities, as long as all are allowed in the MEI regime. DAS is calculated by the main activity (trade or service).

    How to terminate MEI if you need to?

    Go to gov.br/mei > MEI Low. The process is free and online. Pay off all outstanding DAS before closing, as debts remain linked to the CPF even after the write-off.
