LHDN e-Invoice & MyInvois: Phases, the RM1 Million Exemption & What Small Businesses Must Do

The rollout by turnover band

LHDN phased the mandate in from the largest taxpayers downward. Your phase is fixed by annual turnover measured against a reference year LHDN specifies — for the early groups, the audited financial statements for financial year 2022 or the YA 2022 tax return where no audited accounts exist. It is not re-tested against your current year, so a business that has since grown does not automatically move up.

The RM1 million exemption — the change most owners missed

The original design had a further phase pulling in businesses down to RM150,000 of turnover, with everything below RM500,000 exempt. That plan was scrapped. On 6 December 2025 the Cabinet approved raising the permanent exemption threshold from RM500,000 to RM1 million, and IRBM published updated guidelines the following day. The planned final phase for the RM150,000–RM500,000 band was cancelled outright.

The practical effect is that the overwhelming majority of Malaysian micro-enterprises, sole proprietors, freelancers, hawkers and part-time online sellers are now permanently outside the mandate. If your annual turnover is under RM1 million you do not have to issue e-Invoices, register on MyInvois, or buy accounting software to comply.

Note the word permanent. This is an exemption written into the guidelines, not a grace period that expires. It can of course be revised at a future Budget, but there is no scheduled date on which it lapses.

You are exempt — but you are not untouched

• Self-billed e-invoices. When a covered business buys from an exempt supplier and needs the expense to be deductible, it issues a self-billed e-invoice on your behalf. Expect your corporate customers to ask for your TIN and business registration details, and expect them to insist.
• Get your TIN in order. If you have never registered with LHDN, or you trade under a personal name with no tax file, this is where the friction appears. A missing or mismatched TIN is one of the most common validation failures.
• Your own purchases. Suppliers who are in scope will issue you validated e-Invoices rather than ordinary ones. You do nothing except keep them — they are your deduction evidence.
• Crossing the line. Turnover is a threshold, not a permanent status. If you grow past RM1 million, confirm the timeline LHDN applies to newly covered businesses rather than assuming you have another full phase of runway.

If you are in Phase 4, the relaxation is your breathing room

Businesses in the RM1 million to RM5 million band became mandatory on 1 January 2026, but the interim relaxation period for that group has been extended by a further year to 31 December 2027. During the relaxation LHDN will not enforce the penalty provision against a business that has registered on MyInvois and is making a genuine effort to comply.

What the relaxation actually permits is a lighter submission method, not a holiday from the obligation:

• You may issue consolidated e-invoices — one monthly summary rather than a validated document per transaction — including for B2B sales, which are normally excluded from consolidation.
• Product and service descriptions may be given in general terms rather than line-by-line detail.
• Consolidated e-invoices must still be submitted to MyInvois within seven calendar days after the end of the month they cover.
• The RM10,000 carve-out still applies: from 1 January 2026 a single transaction above RM10,000 cannot be swept into a consolidated e-invoice. It needs its own validated document even during the relaxation, and each one wrongly consolidated is a separate exposure.

How a validated e-Invoice actually flows

The mechanics are worth understanding once, because they explain why errors are expensive to fix later. You submit the invoice — through the free MyInvois Portal, or by API from your accounting system, or via an appointed intermediary. LHDN validates it in near real time and returns a unique identifier and a QR code. Only then is it a valid document.

After validation there is a single 72-hour window. Within those 72 hours the buyer may request rejection, giving a reason; if the supplier accepts, the supplier cancels within the same 72 hours. If nobody acts, the e-Invoice is final. After the window closes there is no cancellation — the only route is a credit note, debit note or refund note, each of which is itself an e-Invoice that must be submitted and validated.

The guidelines specify 55 data fields across the document. Most are populated automatically by software, but the identifying ones — TIN, business registration number, SST registration number where applicable, and the classification code for what you sold — are where submissions fail. Validate your counterparties' details once and store them rather than retyping them per invoice.

The penalty for getting it wrong

Failure to issue an e-Invoice where required is an offence under Section 120(1)(d) of the Income Tax Act 1967. On conviction the fine is not less than RM200 and not more than RM20,000, or imprisonment of up to six months, or both — and it applies for each instance of non-compliance, not once per year. A business that quietly kept issuing ordinary invoices for a year is looking at an exposure measured per document.

The second, quieter risk is deductibility. A validated e-Invoice is the supporting document for an expense claim. An expense that should have been supported by one and is not becomes an easy disallowance in an audit, which costs you tax at your marginal rate on top of any penalty.

A short checklist

• Work out your annual turnover against the reference year and confirm which band you fall in. Below RM1 million, stop — you are exempt.
• If covered, register on the MyInvois Portal now. Registration is what keeps the relaxation-period protection available to you.
• Make sure your own TIN, business registration number and SST status are correct in LHDN's records before you submit anything.
• Collect and store TINs for your regular customers and suppliers — this is the single biggest source of rejected submissions.
• Decide between the free portal and API integration on volume. The portal is workable at low volume; above a few dozen invoices a month, manual entry stops being realistic.
• Set a monthly routine for consolidated submissions so the seven-day deadline after month end is never missed.

Important caveats

The e-Invoice timeline has been revised several times — phase dates moved, an entire phase was cancelled, the exemption threshold was doubled, and the Phase 4 relaxation has now been extended twice. The position above reflects the guidelines as at the RM1 million exemption update and the extension of the Phase 4 relaxation to 31 December 2027, but this is exactly the kind of rule that changes again.

Confirm the current phase dates, thresholds and relaxation terms on the official e-Invoice pages at hasil.gov.my before making a compliance decision, and take advice from a licensed tax agent if your turnover sits close to a threshold. This guide explains the framework; it is not a substitute for the guidelines themselves.
