Managing Your Fiscal Obligations and Services

Addressing Common Digital Tax System Challenges

⚠️ Forgot Password or First-Time Access

Cause: User cannot remember their password or has not yet set one for a registered CPF/CNPJ.

Solution: We know being locked out is stressful. The fastest fix is to use the 'Pedir Senha' (Request Password) option on the login page. A 'Senha Web' (Web Password) will be promptly sent to your email address registered with SEFIN. This will allow you to regain access quickly.

⚠️ Unable to Emit Electronic Service Invoices (NFS-e)

Cause: Lack of active registration, incorrect certificate, or system-specific requirements not met.

Solution: Ensure you have an active registration in SEFIN's Municipal Registry (Cadastro Mobiliário). For most companies, an e-CNPJ A1 digital certificate is mandatory for NFS-e emission, while e-CPF or A3 types are usually not accepted. If you are a Microempreendedor Individual (MEI), you should use the National Issuer, not the municipal SIAT system.

⚠️ Portal Functionality Issues (e.g., blank pages, missing elements)

Cause: Web browser settings, specifically JavaScript, are disabled or blocked.

Solution: For the portal to function correctly, your web browser must have JavaScript enabled. Please check your browser settings and allow JavaScript for the SEFIN website.

⚠️ Incorrect or Outdated Registration Email

Cause: The email associated with your tax profile is not current, preventing receipt of important communications like password resets.

Solution: Your contact email for tax purposes is typically linked to your economic registration. Ensure this registration is up-to-date with your current email address. For updates, you may need to initiate an update process with SEFIN, often involving a specific event through Jusepa for companies.
