The MEI (Microempreendedor Individual), a simplified business regime in Brazil designed to help small business owners formalize their work, has monthly and annual obligations. This guide answers the most common questions about DAS, DASN-SIMEI and invoicing.
1. What is DAS and why pay it?
DAS (Documento de Arrecadação do Simples Nacional), which is the monthly tax payment slip used to settle all business taxes at once, is the monthly MEI payment. It includes the social security contribution (INSS), which guarantees retirement and medical benefits, and, depending on activity, ICMS (state sales tax) and/or ISS (municipal service tax). Keeping DAS up to date keeps the CNPJ (corporate taxpayer registry) regular and maintains INSS benefits.
2. How and where do I pay DAS?
Always generate DAS through official government channels. Payment is available via boleto (a popular Brazilian payment slip), Pix (instant digital payment) or automatic debit (depending on the bank). Avoid unofficial sites to prevent scams.
3. What is DASN-SIMEI?
DASN-SIMEI, the mandatory annual tax return that summarizes the yearly financial activity of the business, is the annual declaration. You report the previous year’s gross revenue, even if it was zero. The deadline is May 31 of the following year.
4. Does MEI need to issue invoices?
For individual customers, invoices (Nota Fiscal, the official sales receipt) are not mandatory unless requested. For legal entities, issuing invoices is mandatory. For services, MEIs use the National NFS-e Portal, the official federal website for electronic service invoices.
5. Quick checklist
- Pay DAS every month.
- Submit DASN-SIMEI by May 31.
- Issue invoices when required.
- Keep payment and invoice records.
