Malaysia E-Invoice Implementation Dates: Full Rollout Timeline

We lay out the official five‑phase rollout so businesses know exactly when to adopt the new system and how the grace periods work. The schedule uses FY2022 audited financials or YA2022 tax returns (with proration where relevant) to assign your phase by annual revenue.

Phase 1 for those above RM100m starts on august 2024, and the sequence continues through a phased start in july 2026. Each phase includes a six‑month relaxation window that lets companies consolidate invoices and adjust descriptions before full enforcement.

We highlight practical updates: businesses under RM500,000 turnover remain exempt for now, and penalties under Section 120 of the Income Tax Act 1967 apply if firms fail to comply after the grace period. You will see clear steps to map your phase and choose transmission options, from IRBM’s MyInvois Portal to API integration, so you can act with confidence.

Key Takeaways

• Five-phase rollout tied to FY2022/YA2022 revenue determines your e-invoice implementation date.
• Start dates run from august 2024 to july 2026, each with a six‑month relaxation window.
• Businesses under RM500,000 annual turnover are currently exempt.
• Post-grace rules tighten; penalties under tax law may apply for noncompliance.
• Transmission options include the free MyInvois Portal or API for higher volumes.
• We help companies understand compliance steps and risk mitigation you need know now.

IRBM’s latest updates: What changed in the e-invoicing rollout and why it matters to businesses

The inland revenue has confirmed a revised five‑phase rollout with six‑month relaxation windows for each group. We note that the early phases remain unchanged and smaller taxpayers see extended breathing space.

Revenue Board Malaysia now schedules firms with RM500k–RM1m turnover into the final phase starting 1 July 2026, while those below RM500k stay exempt for now. The relaxation window permits consolidated e-invoices and flexible descriptions, provided core data is captured.

• What this means: six months without penalties under Section 120 if basic requirements are met.
• Practical effect: more time to sequence people, process, and technology changes.
• Action for businesses: plan procurement, controls, and staff training around the timeline.

Malaysia’s five-phase e-invoice timeline by annual turnover

This section lays out each phase by turnover band and the six‑month relaxation each company can expect. We map phases to help you identify the mandatory start and interim leniency.

Phase 1: Over RM100 million

Mandatory from 1 August 2024 with a relaxation window until 31 January 2025. Large businesses should prioritise load testing and vendor coordination.

Phase 2: RM25 million–RM100 million

Starts 1 January 2025; consolidation allowed through 30 June 2025. Use this period to finalise controls and pilot transmissions.

Phase 3: RM5 million–RM25 million

Begins 1 July 2025 with relief to 31 December 2025. Early sandbox testing reduces risk once full validation is required.

Phase 4: RM1 million–RM5 million

Active 1 January 2026 to 30 June 2026. Plan cost‑effective tools that can scale as turnover grows.

Phase 5: Up to RM1 million

Starts 1 July 2026 with a window to 31 December 2026. Note: taxpayers below RM500,000 remain exempt for now.

• Practical note: consolidated e-invoices are allowed during each six‑month window.
• Important change: from 1 January 2026 consolidated invoices over RM10,000 are not allowed and B2B validation becomes compulsory.
• Action: we recommend larger companies finish stress tests early; smaller businesses pick right‑sized tools to scale with turnover revenue.

e-invoice implementation date: how your company’s start date is determined

We determine your rollout phase from FY2022 audited figures or YA2022 tax returns. If your FY2022 year‑end changed, the inland revenue board will prorate turnover to a 12‑month equivalent.

What the Revenue Board Malaysia uses

• FY2022 audited annual turnover or YA2022 annual revenue is the primary basis.
• Proration applies where FY2022 did not cover 12 months to produce comparable turnover revenue.
• Phased notifications will be sent to mandated companies so you know your official start date.

Exemptions and special notes

If your businesses annual revenue is below RM500,000, you are currently exempt from mandatory adoption. New companies commencing from 2023 have an indicative 1 January 2027 target, pending further guidance.

We recommend you reconcile revenue, turnover and tax filings now. Document the basis of your phase determination for audit readiness and coordinate with your accountant on group restructures or partial‑year operations.

Grace and relaxation period: what you can do between your start date and full enforcement

We outline practical actions your team can take during the six-month relief window. The grace period gives companies room to stabilise processes, train staff, and reconcile records without immediate penalties.

Consolidated e-invoices and flexible descriptions during the six-month window

During the relaxation period, monthly consolidated e-invoices may be used for both B2B and B2C to ease operational load.

Keep descriptions clear but concise. Capture the minimum required fields so records remain auditable when full enforcement starts.

What changes after the relaxation period ends

• Separate validation: B2B transactions must be validated individually after the window closes.
• Threshold rule: From 1 January 2026, consolidated invoices are not allowed for transactions over RM10,000.
• Operational tips: migrate high-value flows early, set cutover criteria, and document cancellation/rejection handling within IRBM’s 72-hour window.

Phase-specific compliance requirements and penalties to know

We outline the actions you must take as each relaxation period ends. Companies must prepare for stricter validation, schema checks, and clear audit trails.

B2B validation vs. B2C consolidation and schema compliance with IRBM

After the relief window, B2B transactions require individual validation. B2C may remain consolidated under current guidance.

Schema requirements follow IRBM formats (XML/JSON aligned to UBL 2.1). There are 55 fields with 37 mandatory fields your system must support.

System readiness: data validation, stress testing, automated workflows

We recommend data validation routines and stress testing to avoid rejection spikes. Configure automated workflows for monitoring, resubmission, and exception handling.

Set a clear end-of-relaxation checklist so teams enforce the requirements and reduce manual fixes.

Non-compliance penalties under Section 120 of the Income Tax Act 1967

“Failure to issue required records is an offence under Section 120(1)(d) ITA 1967.”

Penalties range from RM200 to RM20,000 per instance and may include up to six months’ imprisonment. IRBM validation issues a UIN and QR code; supplier and buyer get notifications.

• Tip: log rejection reasons and use the 72-hour cancel/reject window to correct records.
• Tip: align your tax and IT teams early to meet compliance requirements and avoid fines.

Readiness and integration: choosing MyInvois Portal or API and planning your transition

Deciding between the MyInvois Portal and API integration determines your technical and operational path. We guide you to match the transmission method to volume, skills, and cost.

Transmission options: free MyInvois Portal vs API-based integration

MyInvois Portal suits low-to-moderate volumes and keeps software overhead low. It works for many small businesses during the grace period.

API integration is ideal for high volumes. It automates submission, returns UINs and QR codes, and reduces manual work once your system is ready.

Readiness checklist: people, process, technology, and pilot testing

• People: assign governance, train staff, document controls.
• Process: standardize master data and issuance flows to meet IRBM requirements.
• Technology: map fields, test SDKs, and enable monitoring for real-time validation.

“Pilot high-volume lanes first to stabilise mappings and exception handling.”

SME tip: use the relaxation window to pilot both routes, stabilise mappings, and protect revenue by avoiding last-minute rework.

Key dates to mark: August 2024, January 2025, July 2025, January 2026, July 2026

Mark these fixed milestones on your calendar so teams can sequence work, avoid last‑minute changes, and keep suppliers aligned.

Critical timeline entries to record:

• Phase 1: 1 Aug 2024 — relaxation to 31 Jan 2025.
• Phase 2: 1 Jan 2025 — relaxation to 30 Jun 2025.
• Phase 3: 1 Jul 2025 — relaxation to 31 Dec 2025.
• Phase 4: 1 Jan 2026 — relaxation to 30 Jun 2026. From this time, consolidated invoices over RM10,000 are not permitted.
• Phase 5: 1 Jul 2026 — relaxation to 31 Dec 2026; businesses under RM500,000 remain exempt.

Practical actions: schedule checkpoints 60–90 days before each milestone, align peak financial cycles with test windows, and share the calendar with finance, IT and operations.

We recommend SMEs use the july 2026 phase as the last practical test window and document lessons from pilots to speed later rollouts.

Conclusion

Below we summarise practical steps to secure compliance and protect revenue during the rollout.

We recap the five phases and the key implementation anchors so your leadership can finalise program timelines with confidence. Use FY2022 audited figures or YA2022 revenue to map your phase and check any prorated annual turnover calculations with your accountant.

The six‑month relaxation period gives time to consolidate invoices and train teams. Remember: after the grace period B2B validation is mandatory and from 1 January 2026 consolidated invoices over RM10,000 are no longer allowed.

Action now: assign owners, confirm systems, rehearse cutovers, and lock supplier and buyer communications well before the end of your window. Document guidance from the revenue board malaysia and keep tax and transaction controls tight to reduce Section 120 risk.
