E-Invoicing Automation in Malaysia: What Changes in Your Billing Flow

LHDN's e-Invoice mandate is now in its fourth and final phase.

Last updated October 2026
Quick answer

Malaysia's e-Invoice mandate rolled out in four phases by turnover: above RM100 million from August 2024, RM25–100 million from January 2025, RM5–25 million from July 2025, and up to RM5 million from January 2026. Since 1 September 2026, businesses under RM3 million are exempt.

Here's which businesses are covered as of 2026, and what changes in a billing flow once every invoice has to be validated through MyInvois.

The short version: Malaysia's e-Invoice rollout is complete as of January 2026 — since 1 September 2026, every business at or above the RM3 million exemption threshold needs a working MyInvois submission path.

The phase timeline, as it stands in 2026

Phase Effective date Annual turnover (FY2022 basis)
Phase 1 1 August 2024 Above RM100 million
Phase 2 1 January 2025 RM25 million – RM100 million
Phase 3 1 July 2025 RM5 million – RM25 million
Phase 4 1 January 2026 Up to RM5 million (relaxation period to 31 Dec 2027)

The exemption threshold was raised from RM500,000 to RM1 million on 1 January 2026, and then to RM3 million with effect from 1 September 2026 (HASiL media release, 30 August 2026).

Businesses below RM3 million are not required to implement e-invoicing, but the exemption does not apply if a non-individual shareholder, holding company, related company or joint venture has turnover of at least RM3 million.

Why a new billing system is often not needed

Many businesses hear "mandatory e-invoicing" and assume they need new accounting or billing software. Often they don't.

MyInvois is where invoices are submitted for validation. What changes is the step between the system that already creates your quote, order or invoice and LHDN's platform, so the same figures are not typed into a separate portal by hand.

So the first question for your current software vendor is whether it already supports MyInvois submission.

What changes in the billing flow

An invoice already gets created somewhere in your existing process — a POS system, an accounting package, an order system.

Once e-invoicing applies, the required fields (buyer details, line items, tax treatment) go to MyInvois (opens in a new tab) for validation, and the validated invoice, or any rejection that needs correcting, comes back before the invoice is shared with the buyer.

LHDN offers two routes: the free MyInvois Portal for manual, lower-volume submission, and an API for sending invoices straight from your accounting, billing or ERP system. The e-invoice Malaysia hub compares the two.

Questions to ask your software vendor

  • Does the system already submit to MyInvois, by API or through a connector?
  • Does it store the validated invoice and its validation link with the original record?
  • How does it handle a rejected invoice, and a cancellation within LHDN's 72-hour window?
  • Can it issue consolidated e-invoices where your relaxation period still allows them?

Your accounting or billing software vendor is the right place to ask how submission is set up. For the build-or-buy question on business software in general, see the custom software vs SaaS guide.

What to do about it

  1. Confirm your business's turnover band and current phase obligation directly against LHDN's published guidance.
  2. Identify where invoices are currently generated in your existing process — that is the system that needs a MyInvois submission path.
  3. Ask that system's vendor whether MyInvois submission is built in before planning a new system.
  4. Check your phase and mandatory date with the free e-invoice deadline checker.

FAQ

Frequently asked questions

What are the current LHDN e-Invoice implementation dates?

Above RM100 million turnover: 1 August 2024. RM25–100 million: 1 January 2025. RM5–25 million: 1 July 2025. Up to RM5 million: 1 January 2026, with an interim relaxation period to 31 December 2027. Since 1 September 2026, businesses under RM3 million are exempt.

Do I need to replace my billing system for e-invoicing?

Not necessarily. LHDN offers two submission routes: the free MyInvois Portal for manual, lower-volume submission, and an API for submitting from an existing accounting, billing or ERP system. Ask your current software vendor whether it already supports MyInvois before assuming you need a new system.

What happens if my business is below the RM3 million threshold?

From 1 September 2026 you are not required to implement e-invoicing, unless a non-individual shareholder, holding company, related company or joint venture has turnover of at least RM3 million. Check your exact status directly with LHDN or a qualified tax agent rather than assuming exemption by turnover alone.

Does shakalakaa build MyInvois or e-invoicing integrations?

No. shakalakaa does not build, install or manage MyInvois or e-invoicing integrations, and does not give tax advice. This page is general information. For setup, ask your accounting or billing software vendor; for your obligations, ask LHDN or a licensed tax agent.
