How Businesses Register LDHN MyInvois Portal for E-Invoice

If your business operates in Malaysia, you’ll soon need to submit e-Invoices through LHDN’s MyInvois portal. This article will help you to know how to get started, what you’ll need, and what happens after registration.

What is the LHDN MyInvois Portal?

The MyInvois portal is LHDN’s official online platform for e-Invoice submissions and compliance tracking. It helps businesses generate, validate, and manage electronic invoices in a secure and centralised system. The portal is part of the Malaysian government's broader e-Invoice initiative under the Tax Administration System Modernisation plan.

Using the MyInvois portal offers a few key benefits:

Simplifies tax reporting and invoicing
Reduces manual paperwork and errors
Creates better audit trails and faster validation
Keeps your business aligned with digital tax rules

Who Must Register for the MyInvois Portal?

All registered businesses that fall under the e-Invoice rollout by LHDN must register for the portal. This includes:

Large corporations
SMEs
Employers managing payroll and HR systems
Professional services providers

Registration is based on your annual turnover. The LHDN has outlined different mandatory compliance dates depending on your revenue bracket. Even if your business has not yet reached the mandatory phase, early registration is encouraged to prepare in advance.

Step-by-Step: How to Register for MyInvois Portal

Access the official portal at https://myinvois.hasil.gov.my. Login with Identification Card Number. Enter username and password.

Select “MyInvois”. Read the terms and conditions, then click “Continue” to proceed.

Fill in company profile and relevant business information on the taxpayer profile.

Complete the information asked in the User Profile section.

Registration completed, then click “Finish Setup”

Documents Needed for Registration

Before starting, prepare these key documents:

Company registration certificate (SSM)
Taxpayer Identification Number (TIN)
Identification of the authorised person (IC or passport)

After Registration: What’s Next?

Once your registration is approved, your business can begin setting up its e-Invoice processes. This includes:

Connecting your ERP/accounting system (if using API)
Learning to categorise invoices (e.g. B2B, B2C, B2G)
Familiarizing with invoice validation flow on MyInvois

Don’t forget also to assign internal roles: who will handle invoice submission, validation, and daily monitoring.

Deadline and Timeline for Mandatory Compliance

LHDN has provided a phased rollout:

Businesses with annual turnover above RM100 million must start by 1 August 2024
RM25 million to RM100 million: 1 January 2025
RM1 million to RM25 million: 1 July 2025
Below RM1 million: 1 January 2026

Failure to register or comply within these dates may expose your business to tax audits or administrative penalties.
