The Malaysian business landscape is undergoing one of the most important digital transformations in recent years — the nationwide adoption of LHDN-Compliant E-Invoicing. By 2025, nearly all businesses, regardless of size or industry, will be required to issue, receive, and manage invoices through the LHDN’s centralized e-Invoice system.

For many businesses, this shift may seem overwhelming at first. But with the right understanding and the right tools, E-Invoicing can actually simplify operations, reduce errors, improve compliance, and enhance cash flow.

This guide explains everything Malaysian businesses need to know about E-Invoicing in 2025 — from compliance requirements to technical workflows, implementation steps, and how a powerful solution like Plenitude IT’s E-Invoicing Software can simplify the entire process.

What Is LHDN-Compliant E-Invoicing?

E-Invoicing is the digital issuance, validation, and storage of invoices through the IRBM (LHDN) centralized platform.
A business will no longer send invoices directly to customers. Instead:

1. The business generates an e-invoice.
2. The invoice is sent to LHDN for validation.
3. LHDN approves it and returns a Unique Identification Number (UIN) and a validated invoice.
4. The validated e-invoice is then shared with the customer.

This ensures transparency, traceability, accuracy, and tax compliance.

Why Malaysia Is Implementing E-Invoicing

Malaysia’s move toward e-Invoice adoption aligns with global tax digitization trends. The goals include:

• Reducing tax leakages
• Simplifying compliance for businesses
• Standardizing invoicing formats
• Improving data accuracy for LHDN
• Encouraging digital transformation

E-Invoicing Compliance Timeline in Malaysia (2024–2025)

As of 2025, the rollout phases are:

• August 2024 – For companies with > RM100 million turnover
• January 2025 – For companies with RM25 million – RM100 million turnover
• July 2025 – Mandatory for all businesses, including SMEs and micro-businesses

No business will be exempt beyond July 2025.

Types of E-Invoices Required by LHDN

Starting 2025, businesses must issue e-invoices for:

• B2B (Business to Business)
• B2C (Business to Consumer)
• Cross-border transactions
• Self-billed invoices
• Credit notes / debit notes
• Exports & imports
• Online sales and e-commerce transactions

Whether you run a small retail shop, a consultancy, a construction company, or an online store — e-Invoices will be mandatory.

How LHDN’s E-Invoicing Workflow Works

Here’s a simplified look at the process:

1. Invoice Created
   • Generated via system like Plenitude IT E-Invoicing
   • Includes required LHDN data fields
2. Transmission to LHDN
   • Via API or MyInvois portal (manual entry)
3. Validation by LHDN
   • LHDN checks for accuracy & format compliance
   • Validates and approves
4. UIN (Unique Identification Number) Issued
   • Invoice becomes officially recognized
5. Invoice Delivered to Buyer
   • PDF + QR Code
   • Customer can verify authenticity
6. Storage & Record Keeping
   • Business must retain digital records
   • LHDN also keeps all validated invoices

With the right system, this process becomes automated, fast, and error-free.

Mandatory Data Fields Required by LHDN

Your e-Invoices must include specific data points such as:

• Seller & buyer information
• TIN (Tax Identification Number)
• Invoice issuance date
• Item details
• Quantity & pricing
• SST/VAT structure (if applicable)
• Discounts
• Payment terms
• Currency
• Unique invoice ID
• QR verification code after validation

If any mandatory field is incorrect, the invoice will be rejected by LHDN.

Common Challenges Businesses Face in E-Invoicing (2025)

Many Malaysian businesses are facing difficulties such as:

❌ Using outdated accounting systems

Legacy systems cannot communicate with LHDN’s API.

❌ Missing mandatory data fields

Leads to validation errors and delays.

❌ High volume of invoices

Manual MyInvois portal is NOT suitable for medium-to-high invoice volume.

❌ Lack of technical understanding

APIs, schema validation, and integration can be confusing.

❌ Compliance pressure

Ensuring everything matches LHDN requirements takes time.
