MALAYSIA'S E-INVOICE IMPLEMENTATION TIMELINE: KEY DATES & WHAT TO PREPARE

Governments around the world are moving towards e-Invoicing as part of their efforts to modernise tax systems, increase efficiency, and reduce fraud, and Malaysia is keeping pace with this global shift.

Under Budget 2024, The Inland Revenue Board of Malaysia (LHDN) introduced a mandatory e-Invoicing framework that will be rolled out in phases over the following two years. Businesses that fail to comply may face penalties, disruption to cash flow, and even reputational risks. That’s why it’s essential for every business, regardless of size, to understand the key dates, compliance requirements, and steps needed to prepare for this transition.

This guide will walk you through Malaysia’s e-Invoicing timeline, explain who needs to comply, highlight common challenges, and provide practical preparation strategies so you can stay one step ahead.

What is e-Invoicing and Why It Matters?

E-Invoicing is the digital version of a traditional invoice. It contains all the same essential details such as supplier and buyer information, description of goods or services, quantity, unit price, and more.

In Malaysia, e-Invoices are processed through LHDN’s MyInvois system. Here’s how it works in practice:

1. The supplier submits an invoice through their ERP / accounting software via API or uploads it manually through the MyInvois portal.
2. The invoice then goes through a validation process.
3. Once approved, the validated e-Invoice is made available to the buyer.
4. Both the supplier and buyer retain a digital copy for their records.

This process ensures that invoices are accurate, traceable, and compliant with tax regulations. Unlike a simple PDF sent by email, an e-Invoice cannot be altered once validated, which reduces the risk of fraud or human error.

Benefits for businesses:

• Faster processing and payments: Speed up the approval process.
• Lower administrative costs: Reduced paper handling, storage, and manual work.
• Reduced human error: Validation ensures data accuracy and prevents mismatches.
• Greater financial transparency: Easier to track transactions.
• Improved cash flow: Fewer disputes lead to quicker payment processing.

Benefits for government:

• Better tax compliance: Transactions are tracked in real-time.
• Reduced fraud and tax evasion: Harder sale falsification.
• Real-time visibility of revenue flows: Allow overseeing of economic activities more effectively.
• Enhanced data accuracy: Reliable information improves decision-making.

By adopting e-Invoicing, businesses not only meet compliance obligations but also gain operational efficiencies that support Malaysia’s long-term digital economy goals. The Twelfth Malaysia Plan, specifically highlights strengthening digital services infrastructure and digitalizing tax administration as key drivers of growth.

Malaysia’s e-Invoice Implementation Timeline

In line with Budget 2024, Malaysia has announced a phased rollout of e-Invoicing. This allows businesses of different sizes to adapt progressively instead of all at once. The first group began in August 2024, with full adoption required by July 2026.

Based on the LHDN announcement on 5 June 2025, the timeline for mandatory e-Invoicing in Malaysia by annual turnover/revenue is as follows:

• 1 August 2024: Phase 1: Taxpayers with annual turnover/revenue of more than RM100 million.
• 1 January 2025: Phase 2: Taxpayers with annual turnover/revenue between RM25 million and RM100 million.
• 1 July 2025: Phase 3: Taxpayers with annual turnover/revenue between RM5 million and RM25 million.
• 1 January 2026: Phase 4: Taxpayers with annual turnover/revenue between RM1 million and RM5 million.
• 1 July 2026: Phase 5: Taxpayers with an annual turnover/revenue of up to RM1 million.

However, entities with an annual turnover below RM500,000 are currently exempt from the e-Invoicing mandate.

LHDN may grant a grace period after each phase to give businesses time to adjust. During this time, businesses are allowed certain flexibilities such as issuing consolidated e-Invoices. Full compliance and enforcement will apply once this period ends.

Any failure to comply could result in:

• Fines and penalties
• Increased risk of audits
• Disruption to business transactions
• Damage to reputation with customers and partners

Who Needs to Comply?

E-Invoicing is mandatory for all businesses and individuals conducting commercial transactions in Malaysia. This includes:

• Businesses incorporated in Malaysia (local and multinational)
• Sole proprietors, partnerships, LLPs
• Individuals with business income
• Foreign businesses with operations in Malaysia

Moreover, e-Invoicing is only required for businesses and individuals that meet the specified turnover thresholds under the phased rollout announced by LHDN. Entities with an annual turnover below RM500,000 are currently exempt from the mandate.

It’s important to keep in mind that compliance is not just for large corporations but companies across all sectors including manufacturing, retail, e-commerce, F&B, and professional services. Cross-border transactions linked to Malaysian entities will also fall under compliance requirements.

What Businesses Should Prepare Before the e-Invoice Implementation Date

The key to a smooth adoption of e-Invoicing is early preparation, and a successful adoption of it requires more than just system changes. It requires a full review of your business across people, processes, and technology.

Here’s what businesses should focus on before implementing e-Invoice to their business:

1. Internal Readiness
   • Review current invoicing and accounting systems to ensure compatibility with e-Invoicing requirements.
   • Identify gaps in digital capability.
   • Train finance and admin teams on e-Invoice processes.
2. System Integration
   • Ensure ERP/accounting software can integrate with LHDN’s MyInvois system. Quickin makes this process simple with direct, hassle-free integration.
   • Work with vendors to enable API connections.

3. Process Adjustments
   • Standardise invoice formats across all departments to ensure proper data entry.
   • Set up compliance workflows to meet real-time validation requirements.
   • Ensure all teams are aligned to avoid missing or duplicated data.
4. Documentation & Record-Keeping
   • Maintain digital copies as required by LHDN for at least seven years.
   • Ensure proper archiving, backup, and retrieval of data.
   • Secure audit readiness.
