An e-invoice is an invoice in digital form that is sent to LHDN and validated before it is recognised. LHDN's e-Invoice Guideline describes it as a digital representation of a transaction between a supplier and a buyer, and it replaces paper or electronic documents such as invoices, credit notes and debit notes.
So what is an e-invoice, in one sentence? It is the same invoice you issue today — seller, buyer, items, prices, tax, total — but in a data format prescribed by LHDN, and valid only after LHDN has validated it through a system called MyInvois.
This page explains what an e-invoice means, how it differs from an ordinary invoice, how it differs from MyInvois, and what changes for your business.
What an e-invoice means, compared with an ordinary invoice
The meaning of an invoice does not change: it is a commercial document recording a transaction between a seller and a buyer. What changes with e-invoicing is how the invoice becomes valid.
| Ordinary invoice (including PDF) | e-Invoice | |
|---|---|---|
| Format | Any format — paper, Word, PDF | LHDN's data structure (UBL 2.1), in XML or JSON |
| Who sees it first | The buyer | LHDN — it is submitted for validation first |
| When it is valid | When issued | Only after LHDN validates it |
| Identifier | Your own invoice number | Your invoice number, plus the IRBM Unique Identifier Number |
| Proof of validity | No standard way | A QR code that can be scanned to check its status in MyInvois |
| Corrections | Reissue or amend | Cancel within 72 hours, or issue a credit note, debit note or refund note |
A common misconception: an e-invoice is not just an invoice sent by email. A PDF sent by email is an electronic invoice, but it is not an e-invoice in LHDN's sense until its structured data has been validated. The PDF shared with the buyer after validation is only a visual representation of the e-invoice — the QR code on it is what links it to the validated record.
e-Invoice vs MyInvois — what is the difference?
The two terms are often used as though they were the same, when they are two different things:
- e-Invoice is the document and the requirement — the digital invoice you have to issue, and the legal obligation to issue it.
- MyInvois is LHDN's system that receives, validates and stores those e-invoices.
The analogy is simple: the e-invoice is the letter; MyInvois is the post office that validates and records it.
"MyInvois" itself refers to several things:
| Part | What it is |
|---|---|
| MyInvois System | LHDN's back end that validates and stores every e-invoice |
| MyInvois Portal | LHDN's free web portal for creating, submitting and managing e-invoices |
| MyInvois app | The portal's functions on a phone, for iOS, Android and Huawei devices |
| MyInvois API | The connection software uses to submit e-invoices automatically |
| MyInvois e-POS | A digital point-of-sale (POS) platform provided free by LHDN, mainly for MSMEs |
So which one do you "use"? You issue e-invoices, and you submit them to MyInvois — either directly through the portal, or through software connected to the API. How to log in and submit through the portal is covered in MyInvois Portal: how to log in, register and submit e-invoices.
How an e-invoice works
Every e-invoice goes through the same lifecycle, whichever way it is submitted:
- Step 1
Issued
When the sale is concluded, the seller creates the e-invoice and submits it to MyInvois. - Step 2
Validated
LHDN checks the e-invoice. For API submissions, an accepted document can receive a UUID before validation is complete, so check that its status is Valid. A validated document has a validation date, time and link. - Step 3
Notified
The seller and the buyer are notified that the e-invoice has been validated. - Step 4
Shared
The seller shares the e-invoice — or a visual representation carrying the QR code — with the buyer. - Step 5
72 hours
Within 72 hours, the seller can cancel it and the buyer can request rejection. - Step 6
Stored
LHDN stores the validated e-invoice. You still keep your own records.
If an e-invoice fails validation, it is not an e-invoice — the seller has to correct it and submit it again.
Who is involved
- The seller (supplier) — usually the party that issues the e-invoice, and the one responsible for the accuracy of its contents.
- The buyer — receives the e-invoice, and can request rejection within 72 hours. In certain circumstances, such as purchases from foreign suppliers, it is the buyer who issues it — see self-billed e-invoices in Malaysia.
- LHDN — validates and stores e-invoices, but does not issue them on your behalf.
- Intermediaries — service providers you authorise to submit on your behalf, if any.
Not every business has to issue e-invoices. Taxpayers with annual turnover below RM3 million are currently exempt, subject to conditions — see who is exempt from e-invoicing. But even exempt businesses will receive e-invoices from suppliers who are in scope.
What changes for your business
If you are in scope, four things change in practice:
- Data has to be right before the invoice is issued, not after. MyInvois checks submitted data against its validation rules, but Valid status does not guarantee that the transaction details or tax treatment are correct. You remain responsible for them, including the buyer's TIN number, registration number and classification codes. The 55 MyInvois fields explains what is required.
- There is a 72-hour cancellation window from validation. After it closes, use an appropriate credit, debit or refund note to make an adjustment.
- Retail sales are reported monthly. Where a customer does not ask for an e-invoice, you issue an ordinary receipt and report it in a consolidated e-invoice each month — except for activities, and single transactions above RM10,000, that need their own e-invoice outside the interim relaxation period.
- Your implementation date depends on your circumstances, including your revenue history and when you started. Eligible taxpayers in LHDN’s specified group with a mandatory implementation date of 1 January or 1 July 2026 have an interim relaxation until 31 December 2027 — see e-invoice implementation dates.
The practical next step is the LHDN e-invoice compliance checklist.
Common questions
What is an e-invoice for? To record every business transaction in a format validated by LHDN — for sales to businesses, consumers and government. For LHDN, it provides a record of transactions validated in near real time; for businesses, it replaces paper or PDF invoices with a document whose validity can be checked.
Is "e-Invois" the same as "e-invoice"? Yes. "e-Invois" is the Malay term LHDN uses; "e-Invoice" is the English term used in the English version of the guideline. Both refer to the same thing.
Do I have to register for MyInvois? There is no separate MyInvois registration. You reach the MyInvois Portal through your MyTax account.
Are ordinary receipts still valid? Yes, in many cases. Exempt businesses continue to issue ordinary receipts, and businesses in scope can issue receipts to buyers who do not ask for an e-invoice, then report them in the monthly consolidated e-invoice (where consolidation is permitted).
Does an e-invoice have to be printed? Not necessarily. LHDN currently accepts a visual representation — for example a PDF — that carries the QR code of the validated e-invoice.
