LHDN e-Invoice (MyInvois) for Malaysian SMEs: a plain-English guide
Baca panduan ini dalam Bahasa Malaysia →
Malaysia is moving every business onto electronic invoicing through the Inland Revenue Board (LHDN/HASiL) and its MyInvois platform. The change is being introduced in phases based on a business’s annual turnover, so the date it affects you depends on your size. This guide explains what an e-Invoice actually is, how the validation flow works, and the practical steps a small or medium business should take — in plain language, without the jargon.

What is an e-Invoice, and what is MyInvois?
An e-Invoice is a structured digital record of a transaction exchanged between a supplier and a buyer in a machine-readable format. It is not a PDF emailed to a customer. MyInvois is LHDN’s platform where you submit it and LHDN validates it in near-real-time.
The same applies to a credit note, a debit note or a refund — each is a defined data file that LHDN can read, store and validate.
MyInvois is LHDN’s platform for this. Businesses can submit e-Invoices either through the free MyInvois Portal (manual entry, suited to low volumes) or through an Application Programming Interface (API) that lets accounting and ERP software submit invoices automatically. Both routes end at the same place: an invoice that LHDN has validated.
The goal from the tax authority’s side is a clearer, near-real-time view of business transactions, which supports tax administration and reduces invoice fraud. From your side, once your software is set up, it is mostly an extra automated step at the point you issue an invoice.
When does e-invoicing become mandatory for me?
It depends on your annual turnover. As at July 2026, businesses below RM1 million are exempt. The RM1–5 million band is mandatory from 1 January 2026, with an interim relaxation to 31 December 2027. Larger businesses started earlier. Confirm your date with LHDN.
The exemption floor above sits at RM1 million per LHDN’s implementation timeline (updated December 2025), raised from RM500,000 as recently as December 2025 — so verify the current position before relying on it.
One more date matters for the current phase. Businesses in the up-to-RM5 million phase (mandatory from 1 January 2026) have an interim relaxation period to 31 December 2027 — extended by a year in LHDN’s April 2026 FAQ revision — with penalty enforcement starting 1 January 2028. During it, consolidated e-Invoices with general descriptions are accepted — except single transactions above RM10,000, which still need an individual e-Invoice. Verify the relaxation terms against LHDN’s current guidance before you rely on them.
Because these dates and the turnover bands have been adjusted more than once, do not rely on a figure you read in an old article — including this one. Check your specific start date against the current rollout timeline published by LHDN before you plan. The official source is linked at the foot of this guide.
The practical takeaway for an SME: find out which phase you fall into, mark the date, and give yourself a few months of lead time to get your invoicing process ready rather than scrambling at the deadline.
| Phase | Annual turnover / revenue | Mandatory from |
|---|---|---|
| Phase 1 | More than RM100 million | 1 August 2024 |
| Phase 2 | More than RM25 million, up to RM100 million | 1 January 2025 |
| Phase 3 | More than RM5 million, up to RM25 million | 1 July 2025 |
| Phase 4 | RM1 million up to RM5 million | 1 January 2026 — penalties enforced from 1 January 2028 |
| Exempt | Below RM1 million | Exempted — no mandatory date |
These bands and dates have been revised more than once — most recently in December 2025, when the exemption floor rose from RM500,000 to RM1 million. Phase 4’s obligation still starts 1 January 2026; only the penalty-free relaxation period was extended, to 31 December 2027 (LHDN’s April 2026 FAQ revision). Always confirm your start date against the current implementation timeline on LHDN’s official e-Invoice pages.
How does the validation and QR-code flow work?
When you issue an e-Invoice, MyInvois receives it and LHDN validates it in near-real-time. If it passes, LHDN returns a unique identifier and a QR code that links back to MyInvois. You then share the validated invoice, often as a PDF, with your buyer.
The QR code lets the buyer (and, where relevant, LHDN) confirm the invoice is genuine. There is also a short window in which either party can reject or cancel a validated e-Invoice if something is wrong, after which it is considered final.
For transactions where the buyer does not need an individual e-Invoice — for example, many cash sales to walk-in consumers — businesses may issue normal receipts and later aggregate them into a consolidated e-Invoice for the period, within the rules LHDN sets. The detail of what can be consolidated changes as the rollout matures, so treat this as a concept to verify rather than a fixed rule.
What does an SME actually have to do?
Confirm your mandatory start date from your turnover phase. Make sure you can capture the required data, including your buyer’s tax identification details for business-to-business sales. Then choose how to submit: the free MyInvois Portal, or software that connects to the MyInvois API.
Taking those first two steps in turn: confirm your start date from your turnover phase, then make sure you can capture the data an e-Invoice requires — this may mean collecting and storing more information than a simple receipt holds today.
Third, choose how you will submit: the free MyInvois Portal if your volume is low, or invoicing software that connects to the MyInvois API if you issue invoices regularly and want it automated. Fourth, run a short trial before your deadline so your team is comfortable with the flow and you have caught any missing buyer details.
Finally, keep your validated e-Invoices and supporting records as part of your normal bookkeeping. e-Invoicing does not replace good records — it formalises them.
How Taokeh helps
Taokeh, the Malaysian SME accounting software by Enya Venture, keeps e-Invoice readiness in the same ledger you already use for sales, purchases and accounting — not a separate system to reconcile. You raise an invoice once and the supporting data is captured in a structured way.
You store your customers’ tax identification details against their contact record, so the information an e-Invoice needs is on hand at the point of sale rather than chased afterwards. Your invoices stay tied to the underlying accounting entries, which keeps your books and your submissions consistent.
Because Taokeh follows the “don’t pay for what you don’t use” principle, you add the pieces you need as the rollout reaches your turnover band, rather than buying a heavyweight compliance suite up front.
Frequently asked questions
Is a PDF invoice the same as an e-Invoice?
No. A PDF emailed to a customer is not an e-Invoice. An e-Invoice is structured data submitted to and validated by LHDN through MyInvois. You can still share a visual version (often a PDF) of the validated e-Invoice with the QR code on it.
When does e-Invoicing become mandatory for my business?
It depends on your annual turnover. As at July 2026, per LHDN’s timeline: above RM100 million since 1 August 2024; RM25–100 million since 1 January 2025; RM5–25 million since 1 July 2025; and RM1–5 million from 1 January 2026, with an interim relaxation period to 31 December 2027 (extended in LHDN’s April 2026 FAQ revision) and penalty enforcement from 1 January 2028. Businesses below RM1 million annual turnover are currently exempt. These dates have been revised more than once, so check the current timeline on the official LHDN source linked below.
Do I have to issue an e-Invoice for every cash sale to a walk-in customer?
Not necessarily. There are provisions to issue ordinary receipts and later consolidate them into a periodic e-Invoice within LHDN’s rules. The detail of what may be consolidated evolves with the rollout, so verify the current position before relying on it.
Can I just use the free MyInvois Portal?
Yes, for low invoice volumes the free MyInvois Portal with manual entry can work. If you issue invoices regularly, software that connects to the MyInvois API automates the submission and avoids re-keying.
