e-Invoicing in Malaysia: A Guide for Businesses

Everything you need to know about LHDN's MyInvois system and how MSIC codes are used in e-invoicing.

What is e-Invoicing in Malaysia?

e-Invoicing is a digital invoicing system mandated by LHDN (Lembaga Hasil Dalam Negeri Malaysia) — the Inland Revenue Board of Malaysia. Through the MyInvois platform, all businesses in Malaysia are required to issue, validate, and store invoices electronically.

Unlike traditional paper or PDF invoices, e-invoices are structured digital documents that are validated in real-time by LHDN's system. Each e-invoice receives a unique identifier and QR code for verification.

Mandatory for All Businesses

As of August 2024, e-invoicing is mandatory for all Malaysian businesses regardless of revenue size. All businesses must issue e-invoices through the MyInvois system.

How MSIC Codes Relate to e-Invoicing

The MSIC code is a mandatory field on every e-invoice. It classifies the business activity of the supplier (invoice issuer) and must be included in the "Classification" section of the e-invoice document.

How to Find and Use Your MSIC Code

Step 1: Check your SSM registration

Your MSIC code should be listed on your SSM registration certificate (Form 9 / Section 14 Certificate). This is the code you declared during company registration.

Step 2: Verify it matches your activity

Look up your code in our MSIC directory to confirm it accurately describes your current business activity. The code must be a 5-digit item code.

Step 3: Enter in MyInvois

When setting up your MyInvois account or issuing an e-invoice, enter the 5-digit MSIC code in the "Classification" or "Industry Classification" field.

Step 4: Use consistently

Use the same MSIC code across all your e-invoices. If your business has multiple activities, use the code for the primary activity related to each specific invoice.
