MyInvois E-Invoicing in Malaysia

It is mandatory, but phased by annual turnover. It went live for the largest firms (>RM100m) on 1 Aug 2024, then >RM25m on 1 Jan 2025, >RM5m on 1 Jul 2025, and firms up to RM5m on 1 Jan 2026. Since an LHDN update on 30 August 2026, businesses with annual turnover or revenue under RM3 million are exempt (e-Invoice Guideline v4.8, section 1.6), so in practice the January 2026 phase now covers turnover from RM3m up to RM5m. The exemption does not apply to a business that has a non-individual shareholder, a holding company, or a related company or joint venture with turnover of RM3m or more, and LHDN says its exemptions are reviewed from time to time. New businesses have their own start dates: those that began operating in 2023 to 2025 with turnover of at least RM3m start on 1 July 2026, and those starting from 2026 start on 1 July 2026 or when operations begin (or, if first-year turnover is expected to be under RM3m, from 1 January of the second year after turnover reaches RM3m). Exempt businesses can still join voluntarily. For firms up to RM5m, an interim relaxation runs to 31 December 2027, allowing consolidated e-invoices and no Section 120 prosecution for taxpayers who meet its conditions.

Read this carefully. YES, construction is on the official "no-consolidation" list (Specific Guideline v4.9, 7 September 2026, Table 3.6 item 4: a "construction contractor undertaking a construction contract" per the Income Tax (Construction Contracts) Regulations 2007), which in principle means each progress/interim claim must be its own e-invoice rather than batched into a monthly consolidated one. BUT, the interim relaxation in §16.2 of the same guideline expressly permits issuing consolidated e-invoices "for all activities and transactions," construction included, during your grace window. For contractors up to RM5m turnover that window runs to 31 December 2027. So in practice: contractors up to RM5m can still batch claims into a consolidated e-invoice for now; larger contractors (>RM5m, already past their relaxation) must issue individually today; and once the relaxation ends after 31 December 2027, the no-consolidation rule applies to the up-to-RM5m band too. Separately, any single transaction over RM10,000 has been on the same Table 3.6 list since 1 Jan 2026 (item 7), so it follows the same relaxation, and construction-materials wholesalers and retailers are not on the current v4.9 list.

The e-Invoice Guideline (v4.8) describes two transmission mechanisms: the MyInvois Portal hosted by IRBM, and API, either by direct integration of your ERP with the MyInvois System or through Peppol or non-Peppol technology providers. Documents are XML or JSON, and the validator checks invoices against UBL 2.1. IRBM validates in near real-time and, on success, assigns an IRBM Unique Identifier Number, the date and time of validation and a validation link; the visual representation shared with the buyer carries a QR code that checks the e-invoice's existence and status. The supplier can cancel within 72 hours of validation; after that, corrections need a credit, debit or refund note e-invoice. Where consolidation is allowed, the consolidated e-invoice is submitted within seven calendar days after the month end. Buyers issue self-billed e-invoices in set cases, such as purchases from foreign suppliers.

Non-compliance with the e-invoice rules can lead to prosecution under Section 120 of the Income Tax Act 1967, as the LHDN e-Invoice Specific Guideline confirms. The relief: under §16.3 of the Specific Guideline, IRBM will not prosecute during the interim relaxation period, which for businesses up to RM5m runs to 31 December 2027, provided you issue the consolidated e-invoices that §16.2 allows. IRBM also runs an e-Invoice Special Voluntary Disclosure Programme from 7 July 2026 to 31 December 2027 (§17) for businesses that missed e-invoices or submitted ones with errors.

Separate from MyInvois (and run by a different authority: RMCD/Customs, not LHDN), RMCD's FAQ on the 2025 expansion of service tax scope says construction work services are subject to service tax at 6%, and that a provider must register once the value of its taxable construction work services exceeds RM1,500,000 in a twelve-month period. Construction work for residential buildings and the public facilities related to them is not subject to service tax, and the Federal Government, State Governments and local authorities are exempted from paying it. So a contractor can be in scope for MyInvois (income-tax side) and service tax (consumption-tax side) at the same time, through two different portals.

It must reach LHDN by your phase deadline, but there are several routes. The Malaysian accounting tools in our directory (AutoCount, SQL Account, Bukku, Financio, Biztory) and the ERPs (HashMicro, Globe3, IFCA) say they send e-invoices to LHDN, and the developers of AutoCount, SQL Account and Bukku are Peppol certified access points under MDEC; the MyInvois Portal hosted by IRBM is another route. BuildSpace, and the takeoff tools Cubicost and RIB CostX, describe no e-invoicing features, so they pair with an accounting tool for the actual submission. The right question for any vendor: "Do you submit to LHDN directly (or via a Peppol provider), and how do you handle consolidated vs individual e-invoices for a construction contract?"
