A supplier prepares invoice data in the required format and submits it to LHDN/HASiL through the MyInvois Portal or an API-integrated system. The system validates the submitted data against the applicable requirements. If validation succeeds, the e-Invoice receives a Unique Identifier Number (UUID) and validation information.

The supplier then shares the validated e-Invoice or its relevant representation with the buyer. The parties should retain the invoice and related records according to the applicable tax and record-keeping requirements.

Key points

  • The supplier prepares the required invoice data.
  • Submission takes place through the MyInvois Portal or API integration.
  • LHDN/HASiL validates the submitted information.
  • A successfully validated e-Invoice receives a UUID.
  • The supplier shares the validated e-Invoice with the buyer and retains records.
