E-invoicing in Malaysia: the daily work it adds

Since August 2024, more of your supplier bills arrive as e-invoices, validated by LHDN before they reach you. LHDN reports that 265,379 taxpayers have issued more than 1.84 billion of them.

The rules are still moving: the exemption threshold rose to RM3 million on 1 September 2026.

This guide sets out where things stand on 28 September 2026, what it means for purchasing and finance, and where an AI agent can help. It is general information, not tax advice.

Where the phases stand in 2026

LHDN brought e-invoicing in by annual turnover or revenue, based mainly on the 2022 audited accounts or tax return:

Since 1 September 2026, businesses with annual turnover or revenue below RM3 million are exempt. The exemption does not apply where a corporate shareholder, holding company, related company or joint venture has RM3 million or more.

Exempt businesses that have already started may stop without applying to LHDN, so some suppliers may stop sending e-invoices.

The relaxation period is over for most

Each phase had a relaxation period, when consolidated e-invoices were allowed for all transactions and LHDN would not prosecute. For the first three phases it ended by 31 December 2025. For businesses with turnover up to RM5 million, it runs until 31 December 2027.

After it, the full rules apply. Since 1 January 2026, any single transaction above RM10,000 needs its own e-invoice. Failing to issue one is an offence under the Income Tax Act 1967, with a fine of RM200 to RM20,000, up to six months' jail, or both, for each case.

For missed or wrong e-invoices, LHDN runs a special voluntary disclosure programme until 31 December 2027.

What reaches your finance team

Suppliers need your company's tax identification number (TIN) and registration number to issue an e-invoice. LHDN validates it, gives it a unique identifier number and notifies your company through the MyInvois Portal. The supplier then shares it with you, as the e-invoice file or as a copy with a QR code.

Your team is expected to check it. If the price, the quantity or your company's details are wrong, you can request a rejection within 72 hours of validation. After that, only a credit, debit or refund note from the supplier can correct it.

Your PO number is not among the fields LHDN requires, so someone still has to match each e-invoice to its PO and delivery order (DO): the three-way match.

Exempt suppliers still send ordinary bills, which remain proof of the expense. So bills keep arriving in two forms: e-invoices, and ordinary bills on paper, as PDFs and as phone photos.

Self-billed and consolidated e-invoices

In some cases your company issues the e-invoice itself, as the buyer: for example, for goods or services from foreign suppliers, payments to agents, dealers and distributors, and purchases from individuals who are not in business. Each validated one is then shared with the supplier.

These have their own deadlines. For imported goods, it is the end of the second month after the month of customs clearance.

Consolidated e-invoices apply to your sales. For customers who do not ask for an e-invoice, a month's sales can be combined into one consolidated e-invoice, submitted within seven calendar days after the month ends. Some activities, such as construction contracts, cannot be consolidated.

Each rule is simple on its own. Together they add dates to track, and they fall on the same few people every month.

Where an AI agent can help

Picture the days after month-end. Your finance team is matching e-invoices to POs and delivery orders, and chasing a supplier about a wrong price before the 72 hours run out.

An AI agent can take on much of that checking. It can collect e-invoices and ordinary bills in one place, find the PO and delivery order for each, and hold back any bill whose price or quantity does not agree, while there is still time to query it.

A person still decides. The agent asks in the chat before it saves a bill, and your finance team chooses what to accept, what to query and what to enter.

The agent does not submit anything to LHDN, and Customnex is not an e-invoice provider. Submission and rejection stay with your accounting software, your ERP or the MyInvois Portal, handled by your own team.

If you are buying equipment or customised software to implement e-invoicing, ask your tax agent about the accelerated capital allowance rules gazetted for it in April 2026.
