Malaysia e-Invoice Implementation Timeline 2025 Guide

Malaysia’s e-Invoice initiative marks a significant step toward modernizing tax administration and boosting business efficiency. Launched by the Inland Revenue Board of Malaysia (IRBM), this digital invoicing system is designed to improve tax compliance, streamline accounting processes, and support the growth of the nation’s digital economy. The rollout follows a structured five-phase plan, giving businesses of varying sizes—from large corporations to small and medium enterprises (SMEs)—ample time to prepare. Under the updated IRBM timeline, businesses with annual turnover below RM1 million have until 1 July 2026 to comply, with a six-month relaxation period offering flexibility before strict enforcement begins. This phased approach ensures that businesses can transition smoothly while meeting Malaysia’s e-Invoicing requirements.

Key Takeaways

Five-Phase Rollout by Turnover

Malaysia’s e-Invoice rollout runs from Aug 2024 to July 2026, phased by annual turnover.

Six-Month Relaxation Period

Each phase includes a six-month grace period for testing and system adjustments.

SME Exemptions

Businesses with FY2022 turnover below RM500,000 are exempt if MSME criteria are met (not part of a related group above the threshold). If turnover later exceeds RM500,000, the obligation begins 1 January of the second year after that financial year.

Compliance Preparation

SMEs should start ERP integration, staff training, and sandbox testing early.

Early Adoption Benefits

Adopting e-invoicing early boosts efficiency, accuracy, and compliance readiness.

What Is Malaysia’s e-Invoice Mandate?

Malaysia’s e-Invoice Mandate is a government-led initiative by the Inland Revenue Board of Malaysia (IRBM) to digitalize invoicing for improved tax compliance and operational efficiency. The mandate requires businesses to issue electronic invoices (e-invoices) for certain transactions, replacing traditional paper-based invoices with a standardized digital format that integrates directly with IRBM’s MyInvois system.

Scope and Transactions Affected

The e-Invoice Mandate applies to both B2B and B2C transactions, phased by FY2022 annual turnover. From 1 Jan 2026, transactions exceeding RM10,000 must be issued as individual e-invoices. Consolidated e-invoices are still permitted only for IRBM-approved low-value or B2C cases, while specific categories (e.g., motor vehicles, flight tickets, luxury items) are not eligible for consolidation.

Exemptions

To reduce compliance burden on smaller enterprises, businesses with annual turnover below RM500,000 are fully exempt from the e-Invoice Mandate. However, businesses above this threshold are encouraged to adopt e-invoicing early to ensure smooth compliance when their phase becomes mandatory.

This structured approach ensures that businesses of all sizes can transition efficiently to e-invoicing while maintaining accurate tax reporting and minimizing penalties under Section 120 of the Income Tax Act 1967.

Updated e-Invoice Implementation Timeline in Malaysia

The Malaysia e-Invoice Mandate follows a phased rollout based on business turnover, giving companies sufficient time to comply according to their size. The Inland Revenue Board of Malaysia (IRBM) has structured this rollout into five phases, each with a mandatory start date and a six-month relaxation period to ease the transition. This approach ensures smooth adoption while maintaining tax compliance.

Phased Implementation Table

Updated by IRBM on 5 June 2025 (official implementation schedule)

Key Takeaways for SMEs

• Businesses with annual turnover below RM500,000 are fully exempt from e-invoicing.
• The relaxation period allows SMEs to issue consolidated e-invoices and adjust systems without penalties.
• Early adoption is encouraged for SMEs to test systems, train staff, and integrate with MyInvois before full compliance becomes mandatory.
• Transactions above RM10,000 require individual e-invoices, highlighting the importance of system readiness even for smaller businesses.

Relaxation Periods Explained

To ease the transition, IRBM provides a six-month relaxation (soft-landing) period for each phase. During this grace period, businesses may issue monthly consolidated e-invoices in line with IRBM’s schema and will not face Section 120 prosecution if they comply with these consolidated rules. This window allows gradual system adjustment and staff training before strict enforcement.

Key Flexibilities During the Relaxation Period

• Consolidated Invoicing: Businesses can issue consolidated e-invoices for multiple transactions, including B2B invoices, instead of generating separate e-invoices for each transaction.
  
• Product/Service Description Leniency: More flexible descriptions are permitted, giving businesses time to standardize their invoicing formats and align with IRBM’s schema requirements.
  
• No Penalties: As long as the minimum requirements are met, businesses will not face penalties under Section 120 of the Income Tax Act 1967 during the relaxation period.

How SMEs Can Use This Period

SMEs can use this period to test system integrations, train staff, and ensure accurate data capture. Early adoption during the relaxation period is recommended, especially for businesses approaching the RM1 million turnover threshold, to avoid last-minute compliance challenges. The grace period provides an opportunity to identify and resolve operational gaps without financial or legal repercussions. By leveraging the relaxation period, businesses can ensure a smooth and compliant transition to Malaysia’s digital invoicing system while benefiting from operational flexibility.

Compliance Requirements For Each Phase

Malaysia’s e-Invoice mandate follows a five-phase rollout, with compliance obligations tailored to business size. Understanding these requirements is critical to avoid penalties and ensure seamless integration with IRBM’s MyInvois system.

Penalties For Non-Compliance

Under Section 120(1)(d) of the Income Tax Act 1967, failure to comply with Malaysia’s e-Invoicing requirements is considered an offense. Businesses that do not issue e-invoices according to their designated phase may face both financial and legal consequences.

Fines and Imprisonment

• Monetary penalties: Non-compliant businesses can be fined between RM200 and RM20,000 for each instance of non-compliance.
• Imprisonment: In severe cases, offenders may face up to six months in jail, or both fines and imprisonment.
• Enforcement timeline:
  • Phase 1 businesses faced enforcement starting 1 February 2025.
  • Phase 2 enforcement began 1 July 2025, with subsequent phases following after their respective relaxation periods.

Importance of Timely Adoption

• Smooth transition: Leveraging the six-month relaxation period per phase reduces the risk of errors and ensures compliance with IRBM guidelines.

For businesses, timely adoption is especially crucial. Preparing your systems, digitizing data, training staff, and performing sandbox testing can prevent costly fines and operational disruptions.By proactively complying with Malaysia’s e-Invoice mandate, businesses not only avoid penalties but also enhance operational efficiency and strengthen tax compliance.

Benefits of Early Adoption For SMEs

For small and medium enterprises (SMEs) in Malaysia, adopting e-Invoicing ahead of mandatory deadlines offers significant advantages beyond mere compliance.

1. Operational Efficiency and Cost Reduction

Early adoption allows SMEs to streamline invoicing processes, reduce manual errors, and cut administrative costs. Automated e-invoicing minimizes paper usage, accelerates payment cycles, and frees up staff to focus on higher-value tasks.

2. Seamless B2B and B2C Transactions

By integrating e-Invoicing systems early, businesses can manage both B2B and B2C invoicing efficiently. Consolidated invoicing options during the relaxation period help simplify transaction management, ensuring accurate reporting and smoother communication with clients and suppliers.

3. Better Readiness for Full Compliance

SMEs that implement e-Invoicing ahead of schedule can perform system readiness checks, ERP integration, staff training, and sandbox testing without the pressure of looming deadlines. This proactive approach ensures a smooth transition to full compliance when the relaxation period ends, reducing the risk of errors and penalties.

In short, early adoption positions SMEs to improve operational efficiency, enhance transaction accuracy, and build long-term compliance resilience, all while leveraging the flexibility offered during Malaysia’s e-Invoice relaxation periods.

How To Determine Your e-Invoice Implementation Phase

Malaysian businesses can determine their mandatory e-Invoice implementation phase based on their FY2022 annual turnover. Understanding your phase is crucial to ensure timely compliance and avoid penalties under Section 120(1)(d) of the Income Tax Act 1967.

Note: Phases are determined based on FY2022 turnover (for new entities, IRBM will assign the appropriate phase upon registration).
