Selling online in Brazil:
do you need a CNPJ?

Can I sell online using a CPF?

When assessing a platform or payment provider, check whether individual registration is accepted, which documents are required and which terms apply to your activity. Approval does not replace business regularization.

Occasionally selling a used personal item differs from buying goods for resale and maintaining a catalog, inventory and ongoing campaigns. These examples help describe your operation to an accountant; they are not an automatic legal test or permission to trade without registration.

When should an online store obtain a CNPJ?

If you are building a retail business, treat formal registration as part of launch planning. Do not wait for a payment block or a supplier's document request to organize it.

Bring a simple operational map to your accounting consultation:

• What you will sell, where the goods come from and where they will be stored.
• Whether you manufacture, resell, import or simply broker sales.
• Which channels you will use: your website, marketplaces, WhatsApp or social media.
• Who buys, how they pay and where products will be shipped.
• Expected revenue, costs and hiring plans.

Do not treat the MEI revenue limit as an allowance for selling under a CPF. Your framework and registration timing should reflect the activity, not just the amount received in your account.

Can an online seller register as MEI?

Yes, if the activity and entrepreneur meet the requirements. General conditions include an allowed occupation, annual revenue up to R$81,000, no more than one employee, and no participation in another company as partner, manager or owner. Paraná Commercial Registry: MEI requirements ↗

“Selling online” describes a channel. To select an occupation, consider the actual product or service sold. Check the official activity list and specific rules before registering.

The quoted limit is a general reference. New businesses, special situations and rule changes require specific checks. If MEI does not fit, ask for a comparison of other company and tax frameworks.

Does an online store need to issue tax invoices?

It depends on the framework, transaction and applicable rules. MEI regulations include both exemptions and mandatory issuance; it is incorrect to conclude that MEI never needs a tax document. CGSN Resolution 140/2018, article 106 ↗

CGSN has also announced changes for 2027 expanding MEI invoicing rules. Check effective dates before applying older guidance to your store. CGSN: tax reform adjustments ↗

Confirm the appropriate document with your accountant and the relevant state or municipal tax authority. Ask your invoicing provider to test your actual products and scenarios, including returns and cancellations.

Define when an order can proceed to shipping, how staff identify a rejected tax document and where customers receive it. Avoid relying on manual checks without an assigned owner.

What should you prepare to open an online store?

Once your business framework is underway, turn those decisions into an operation customers can use and your team can monitor.

1. Clear registration and offers. Organize supplier identification, contact details, product features, total prices and delivery terms.
2. Verified payment ownership. Validate accepted documents, settlement accounts, deadlines and fees with your selected provider.
3. A prepared catalog. Gather photos, descriptions, variants, dimensions and weights. Have tax information validated by those responsible.
4. Connected inventory and orders. Define which system controls available stock and how to prevent sales of unavailable items.
5. Tested delivery and after-sales support. Simulate a full purchase, confirmation message, support request and return request.

Brazil's E-commerce Decree requires clear supplier and offer information, accessible support and ways to exercise withdrawal rights. Its reference to CPF or CNPJ identification does not waive other business obligations. Decree 7,962/2013, articles 2, 4 and 5 ↗
