When do penalties for e-invoicing start?

The first three phases’ relaxation periods ended in 2025, so penalties can apply to those businesses now. For businesses with turnover up to RM5 million, LHDN has extended the relaxation period to 31 December 2027, with full enforcement from 1 January 2028. Non-compliance can carry a fine of RM200 to RM20,000 per offence.

What is a consolidated e-invoice?

A consolidated e-invoice combines transactions where the buyer did not ask for an individual e-invoice, typically retail sales, into one monthly e-invoice. It must be issued within seven calendar days after the end of the month. During relaxation periods LHDN allows wider use of consolidation, but it must still be monthly.

Should we use the MyInvois Portal or the API?

The free MyInvois Portal suits low volumes and spreadsheet batch uploads. The API suits businesses whose accounting, ERP or POS systems can submit directly. Many companies use their accounting package’s built-in connector and add automation around it for data clean-up, consolidation, monitoring and matching.

Can AI prepare e-invoices for LHDN?

AI can read supplier documents, suggest classification codes, check for missing buyer details and draft follow-up emails. Final tax treatment and submission should run through rules-based validation and human approval for exceptions. Automation tools such as n8n can call the MyInvois API and combine both.

Automating LHDN MyInvois e-Invoicing in Malaysia (2026)

Q: What is the e-invoice exemption threshold in Malaysia in 2026?

From 30 August 2026, businesses with annual turnover below RM3 million are exempt from mandatory e-invoicing, up from RM1 million. The exemption does not apply if a corporate shareholder, holding company, related company or joint venture has turnover of RM3 million or more. Check LHDN’s latest timeline and FAQ for your position.

Automating LHDN MyInvois e-invoicing in 2026

The exemption moved to RM3 million on 30 August 2026. Here is where the rules stand, and the five places automation takes the manual work out of month-end.

By Chan Wei Khjan 2026-09-03 8 min read

On 30 August 2026 the e-invoicing exemption threshold moved again, from RM1 million to RM3 million in annual turnover. For many small businesses that is a reprieve. For every company above the line, and for every business that buys from one, e-invoicing through LHDN’s MyInvois system is now part of month-end. The question I get from finance teams is no longer whether to comply but how to stop it eating two days a month. That is an automation problem, and a solvable one.

Not tax advice. Thresholds and relaxation periods have changed several times. Confirm your own position against LHDN’s timeline and FAQ, linked below, or with your tax agent.

Where the rules stand in September 2026

Annual turnover	Mandatory from
Above RM100 million	1 August 2024
RM25 million to RM100 million	1 January 2025
RM5 million to RM25 million	1 July 2025
RM3 million to RM5 million	1 July 2026 (relaxation to 31 December 2027)
Below RM3 million	Exempt (from 30 August 2026), unless a related company is at or above RM3 million

Three details catch people out. First, the exemption does not apply if a corporate shareholder, holding company, related company or joint venture has turnover of RM3 million or more. Second, if your turnover first reaches RM3 million in YA2026 or later, e-invoicing starts on 1 January of the second year after that. Third, during the relaxation period you may issue consolidated e-invoices, but still monthly, and within seven calendar days of month-end. Full enforcement for the last phase starts on 1 January 2028. Non-compliance can carry a fine of RM200 to RM20,000 per offence under the Income Tax Act.

Portal or API?

LHDN gives you two ways in. The MyInvois Portal is free and handles single invoices or spreadsheet batch uploads. The API connects your systems directly. Most accounting packages sold in Malaysia now include a MyInvois connector, and if yours does, use it. Automation earns its keep in the gaps around the connector, which is where the manual hours hide.

Five places automation saves the most time

An e-invoicing automation map for finance teams

1
Buyer data clean-up
An agent checks customer master data for missing TINs, ID numbers and addresses before invoices fail validation, and drafts the email asking the customer for what is missing.
2
Consolidated invoices from POS or e-commerce
A monthly workflow pulls sales from your POS, Shopee or Lazada exports, groups them, and prepares the consolidated e-invoice well inside the 7-day window.
3
Validation monitoring
A daily check of submission status that flags rejections with the reason, so someone fixes them the same day.
4
The 72-hour cancellation window
A validated e-invoice can be cancelled within 72 hours. An alert when credit notes or cancellations are requested stops the window being missed.
5
Matching supplier e-invoices
Incoming validated e-invoices are matched against purchase orders and the purchase ledger, with only the exceptions sent to a person.

None of this needs a developer. In our n8n automation course, finance participants build the POS consolidation and the rejection monitor on day one, calling the MyInvois API from n8n and using Claude or GPT to read messy supplier documents. If your company is on Microsoft 365, the same logic works in Copilot Studio; see agentic finance automation with Copilot 365.

Where AI helps, and where it must not

Large language models are good at the messy edges: reading a supplier’s scanned invoice, working out which classification code a line item probably belongs to, drafting the chaser email. They should not be the final authority on tax treatment. The pattern that works is AI prepares, rules validate, a person approves anything unusual. That is the same principle we teach for AI in tax compliance and reconciliation.

If you are now exempt

Businesses under RM3 million with no large related companies can stop preparing for mandatory issuance, but they will still receive e-invoices from suppliers above the threshold. Keeping those organised and matched to payments is worth automating anyway. It is the cheapest month-end improvement a small finance team can make.
