Yes, e-invoicing is mandatory in Malaysia for businesses and taxpayers that fall within the implementation requirements set by the Inland Revenue Board of Malaysia (LHDN/IRBM). It applies to companies, sole proprietors, partnerships, limited liability partnerships, corporations, branches, cooperatives, trusts, and other legal business entities. The requirement covers B2B, B2C, and B2G transactions. Implementation is based mainly on annual turnover or revenue: e-invoicing More than RM100 million: 1 August 2024 More than RM25 million up to RM100 million: 1 January 2025 More than RM5 million up to RM25 million: 1 July 2025 Up to RM5 million: 1 January 2026 Businesses with annual turnover or revenue below RM1 million are generally exempt from implementing an electronic invoicing system. However, the exemption may not apply when the business is connected to a larger company, such as a subsidiary, related company, joint venture, or an entity with a non-individual shareholder whose turnover reaches the required threshold. Businesses that are required to comply must create and submit invoices through the MyInvois Portal or approved e-invoicing software Malaysia integration. Using a reliable e invoicing system helps businesses validate invoices, maintain proper tax records, and meet LHDN requirements.
