Taxpayer Login
Taxpayer Login in Malaysia’s e-Invoice System
To access and use Malaysia’s MyInvois system (the platform for managing e-Invoices), every business or taxpayer needs to go through a secure login process. This ensures that only authorized parties can submit or retrieve e-Invoices through the API or portal.
The Taxpayer Login is the official access point for businesses (registered with LHDN) to interact with the e-Invoice system. This login is needed for both manual users (through the portal) and system-to-system connections (API integration). There are two key elements used in API-based login:
Tax ID
The Tax ID is a unique identifier assigned to each taxpayer (business or individual) by LHDN. It is usually your:
- Company's Income Tax Number (TIN) for companies
- NRIC or business registration number, depending on your entity type
This Tax ID is used to identify which taxpayer is sending or receiving the e-Invoice through the MyInvois system.
Tax Secret
The Tax Secret is like a secure password or access token. It is generated by LHDN and used along with the Tax ID to authenticate your connection to the MyInvois API. Think of it as the private key that proves your system is authorized to submit e-Invoices on behalf of your company.
- It must be kept confidential and not shared publicly
- It is usually generated from the MyInvois portal under your profile or integration settings
- It is required when calling API endpoints for invoice submission, validation, or retrieval
When integrating with the e-Invoice API, your system must include both the Tax ID and Tax Secret to log in securely. Once authenticated, your system can then submit invoices, retrieve status updates, and interact with LHDN’s backend.
