e-Invoice Malaysia: The 2026 Guide to Exemption, Phases, and MyInvois

On 30 August 2026 the Inland Revenue Board (LHDN) raised the e-Invoice exemption threshold from RM1 million to RM3 million in annual turnover, effective 1 September 2026. LHDN says more than 1.1 million businesses benefit. If you read anything about e-Invoice in Malaysia before that date, including our own earlier guide, the threshold it quotes is wrong. This page is the replacement. Every figure on it was checked against the official LHDN implementation timeline on 7 September 2026, and the timeline page itself carries the date 30 August 2026.

This guide is for owners, finance leads, and admin staff who need a straight answer to three questions: does the mandate apply to me, what exactly do I have to do, and what can I safely ignore. It is written from Kuching, where a large share of registered businesses have just moved out of scope, but the rules are national.

What Changed on 30 August 2026

LHDN published e-Invoice Guideline version 4.8 on 30 August 2026 and updated the implementation timeline the same day. The single change that matters: taxpayers with annual turnover or revenue below RM3,000,000 are exempt from e-Invoice implementation. The previous threshold was RM1,000,000, set on 7 December 2025, and before that RM500,000. The Star reported LHDN as saying over 1.1 million businesses benefit from the higher threshold.

Nothing else in the schedule moved. The four phases and their dates are the same, and all four have already started. The practical effect is that Phase 4, published as "up to RM5 million", now covers businesses between RM3 million and RM5 million. Everyone below that line has no e-Invoice deadline at all.

Do You Have to Comply? Work Through It in This Order

Check your position in this sequence. Most businesses stop at the first line.

• Annual turnover below RM3,000,000: you are exempt. No phase and no implementation date applies to you. You do not need to register, buy anything, or change how you invoice.
• Annual turnover of RM3,000,000 or more: you are in scope, and your implementation date has already passed. You should be issuing e-Invoices now, either through the MyInvois portal or through software connected to it.
• Part of a group: the exemption does not apply if you have a non-individual shareholder, a holding company, a related company, or a joint venture partner with turnover of RM3 million or more. A small subsidiary of a large group is still in scope.
• Close to the line, or growing: you enter the mandate when you cross it. Choose e-Invoice-capable accounting software at your next natural upgrade rather than migrating under time pressure later.
• Exempt but selling to large companies: your customers may still ask for compliant invoices or issue self-billed e-Invoices on your behalf. Exempt does not always mean unaffected. See the FAQ at the end of this page.

LHDN measures turnover on the 2022 financial year: audited accounts where they exist, otherwise the tax return for the year of assessment 2022. If your business started in 2023 or later, the guideline has its own rule for new businesses. Read that section of the current guideline before assuming which band you are in.

What e-Invoice Actually Is

e-Invoice, or e-Invois in Bahasa Malaysia, is not a PDF sent by email. It is a structured document, in XML or JSON, submitted to LHDN through the MyInvois system and validated in near real time. The sequence for every document is the same:

• You create the invoice in the MyInvois portal, or your software creates it and submits through the MyInvois API.
• LHDN validates the mandatory fields, around 55 of them, including your TIN, business registration number, MSIC code, the buyer's TIN, and item classification codes.
• A validated document receives a unique identifier number (UIN), a validation timestamp, and a QR code. This is the proof that the invoice exists in LHDN's records.
• You share the validated invoice with your buyer, usually as a PDF or printout carrying the QR code, so they can verify it.
• The buyer has 72 hours from validation to reject it, and you have 72 hours to cancel it. After that, corrections need a credit note, debit note, or refund note, which are themselves e-Invoices.

The document types in scope are invoices, credit notes, debit notes, refund notes, and self-billed versions of each. Self-billed e-Invoices are issued by the buyer when the supplier cannot issue one, for example a foreign supplier, an individual who is not in business, or an exempt Malaysian supplier who has not adopted e-Invoice.

The Four Phases, as LHDN Publishes Them Today

This is the schedule on the official timeline page, checked on 7 September 2026. Four phases, all already live, plus the exemption below them:

• Phase 1, 1 August 2024: annual turnover above RM100 million.
• Phase 2, 1 January 2025: annual turnover above RM25 million up to RM100 million.
• Phase 3, 1 July 2025: annual turnover above RM5 million up to RM25 million.
• Phase 4, 1 January 2026: annual turnover up to RM5 million. With the new exemption, this band now runs from RM3 million to RM5 million in practice.
• Exempt: annual turnover below RM3,000,000, from 1 September 2026. No implementation date.

There is no Phase 5. A fifth phase for the smallest businesses was expected around 1 July 2026 under the old schedule, but the businesses it would have covered became exempt first at RM1 million and are now exempt at RM3 million. If a vendor tells you that you must comply because of "Phase 5", they are working from a schedule that no longer exists.

The RM10,000 Rule and Consolidated e-Invoices

Businesses in scope do not have to issue an individual e-Invoice for every small retail sale. B2C transactions where the buyer does not ask for an e-Invoice can be grouped into one consolidated e-Invoice per month, submitted within seven calendar days after the month ends. Two limits apply:

• From 1 January 2026, any single transaction above RM10,000 must have its own individual e-Invoice. It cannot go into a consolidated one. This rule is enforced from that date and is not relaxed.
• If a buyer asks for an individual e-Invoice, you must issue one, whatever the amount.

Some industries were never allowed to consolidate, including motor vehicle sales, flight tickets, luxury goods and jewellery, construction, and licensed betting and gaming. If you are in one of those, every transaction needs its own e-Invoice regardless of value.

The Relaxation Period, and Why the End Dates Disagree

Each phase came with an interim relaxation period. During it, LHDN allows consolidated e-Invoices for all transactions, including B2B, accepts a description of goods in place of some mandatory fields, and has said it will not prosecute for non-compliance with those consolidated rules. The RM10,000 individual e-Invoice rule is the exception and stays in force.

The end date of the relaxation for the Phase 4 band has been revised more than once, and third-party guides still disagree with each other. We have seen 30 June 2026, 31 December 2026, and 31 December 2027 all stated with confidence, and the official timeline page does not settle it. We are not going to add another confident date to that pile. If the relaxation end date affects a decision you are making this month, confirm it against the LHDN timeline or the current guideline PDF on the day you need it. The thresholds and phase dates on this page are stable. The relaxation dates are not.

Three Ways to Submit: Portal, Software, or API

If you are in scope, there are three routes to MyInvois, and two of them cost nothing.

• The MyInvois portal. LHDN's own web interface. Free, legally sufficient, and the right answer for low invoice volume. Every invoice is keyed by hand, so it becomes a daily job past roughly 20 to 30 invoices a month.
• e-Invoice-ready accounting software. Most current Malaysian packages, including Biztrak MSB and Biztrak Online, submit to MyInvois as part of normal billing. You raise the invoice once, the software submits it, and the UIN and QR code come back into the record.
• API integration into a system you already run. For an ERP, POS, or custom system that cannot sensibly be replaced, a middleware layer maps your invoices to the MyInvois format, submits them, stores the validated result, and queues rejections for correction. It is a project rather than a purchase.

Which route fits depends on your invoice volume and the systems you already have, not on a product catalogue. We compare the three honestly, including when you should not buy anything, on the e-Invoice software page.

What to Prepare Before Your First e-Invoice

Most first submissions fail on master data, not on software. Have these ready before you register or connect anything:

• Your Tax Identification Number (TIN) and business registration number (BRN), matched exactly to what LHDN holds. Mismatches are the most common validation error.
• Your MSIC code, the five-digit industry classification, updated with LHDN if your activity has changed.
• Access to MyInvois through the MyTax portal, with the director or an authorised representative set up as the administrator.
• Your customers' TINs. Every B2B e-Invoice needs the buyer's TIN. Start collecting them now; a general TIN exists for buyers who do not provide one, but only in the cases the guideline allows.
• Item classification codes for what you sell, from LHDN's published list.
• A digital certificate from an LHDN-approved provider if you will submit through the API. The portal does not need one.
• A sandbox test before go-live. Submit sample invoices, a credit note, and a rejection case, and make sure your team knows what a failed validation looks like.

The Part Vendors Skip: Supplier e-Invoices Still Arrive as PDF

e-Invoice fixes the sending side. On the receiving side, the validated invoice from your supplier usually still lands in your inbox as a PDF with a QR code, and somebody still keys it into your accounting system. For a business receiving hundreds of supplier invoices a month, the mandate changed the format of the document and left the data entry exactly where it was.

That gap is where automation earns its place. Invoice OCR reads the supplier PDF, extracts the supplier, amounts, and line items, checks them against the purchase order, and posts the entry, with the UIN kept against the record. For businesses that also receive statements, delivery orders, and forms, the same pipeline extends to AI document processing. Neither is required for compliance. Both remove the work compliance did not.

What Non-Compliance Costs

Failing to issue an e-Invoice when required is an offence under Section 120(1)(d) of the Income Tax Act 1967. The penalty is a fine of RM200 to RM20,000, imprisonment of up to six months, or both, for each offence. LHDN has said it will not prosecute for non-compliance with the consolidated e-Invoice rules during a relaxation period, provided the taxpayer complies with those consolidated rules. That protection does not extend to the RM10,000 individual e-Invoice rule, which is enforced from 1 January 2026.

The more common cost is not a fine. It is a large customer refusing to pay an invoice that has no UIN, or an auditor asking for validated e-Invoices you cannot produce. Both are avoidable with the portal alone.

Common Mistakes We See in Kuching and Across Sarawak

From our work with businesses in Kuching and around Sarawak, these are the pitfalls that come up most:

• Paying for compliance you do not need. Businesses under RM3 million buying software or subscriptions because a vendor quoted an old threshold.
• Assuming the accounting software is compliant without checking the specific version and whether the e-Invoice module is actually switched on and configured.
• Forgetting self-billed e-Invoices for foreign suppliers, individual contractors, and exempt local suppliers. These are in scope for the buyer.
• Outdated LHDN profile details. A wrong MSIC code or an old business address causes validation failures that look like software bugs.
• Treating e-Invoice as an IT-only job. It needs finance, admin, and IT in the same room, because most failures are data failures.
• No rejection process. A validated e-Invoice that the buyer rejects within 72 hours needs somebody to see it and act. If nobody owns that inbox, the customer chases you a month later.

How GreatRise Handles e-Invoice in Sarawak

For businesses using Biztrak, one of the most widely deployed accounting platforms in Sarawak, the e-Invoice integration is built in. Biztrak connects directly to the MyInvois API, submits invoices on approval, retrieves the UIN and QR code, and stores everything against the original record. Credit notes, debit notes, and self-billed invoices go through the same connection. As an authorised Biztrak implementation partner, GreatRise IT has been deploying these configurations across Sarawak since Phase 1. A typical setup takes three to five business days, including sandbox testing and go-live validation.

For a system that cannot be replaced, we build the MyInvois API integration around it as a fixed-scope sprint, typically RM 8,000 to 15,000 over two to three weeks, quoted in writing before work starts. Onsite across Sarawak from Kuching, remote for the rest of Malaysia. And if a two-minute turnover check shows the mandate does not apply to you, we say so on the call and do not write a proposal.

Your Action Plan This Month

If you have not sorted e-Invoice yet, do these in order:

• Confirm your band. Annual turnover on the 2022 accounts, and whether any shareholder, holding company, or related company is at RM3 million or more. Under RM3 million with no group link: stop here, you are exempt.
• Verify your LHDN profile: TIN, BRN, MSIC code, and address, all current.
• Check your accounting software version against the vendor's e-Invoice compliance notes, or ask your IT partner to.
• Register on MyInvois through MyTax and set up your administrator and, if needed, your API credentials.
• Test in the sandbox: sample invoices, a credit note, and a deliberate rejection.
• Go live and watch the first batch of real submissions for validation failures.
• Train the people who raise invoices and the person who owns rejections. Give the rejection inbox a name.

Do Not Let Anyone Sell You a Deadline You Do Not Have

The most useful thing on this page may be the part that saves you money. If your annual turnover is under RM3 million and you are not part of a larger group, you are exempt, and any quotation that opens by telling you that you are about to miss a mandate deserves a hard question. Ask the vendor which turnover band they are placing you in and which LHDN date they are citing. If they say RM1 million, RM500,000, or "Phase 5", they are reading a schedule that LHDN replaced on 30 August 2026.
