Malaysia's e-invoicing deadlines, by phase
LHDN rolled out mandatory e-invoicing in turnover-based phases rather than all at once — which means the actual deadline that applies to a business depends entirely on its annual turnover band, not a single date. The exemption threshold has already been raised once since the mandate was first announced, so the safest approach is to confirm your business's current phase directly with LHDN or your accountant rather than relying on any single source, including this one, as final.

The phases, by turnover
Phase 1 covered the largest businesses (turnover above RM100 million). Phase 2 captured mid-tier corporations, turnover between RM25 million and RM100 million, from 1 January 2025. Phase 3 covers turnover between RM5 million and RM25 million, from 1 July 2025 with a relaxation period through the end of 2025. Phase 4 covers turnover between RM1 million and RM5 million, live from 1 January 2026.
Each phase has come with a relaxation period — typically around six months — during which LHDN eases enforcement while businesses in that band transition. That relaxation period is not an extension of the deadline itself; it changes how strictly early non-compliance is treated, not when the obligation starts.
The exemption threshold, and that it has already moved once
The exemption threshold was raised from RM500,000 to RM1,000,000 in annual turnover, effective 1 January 2026 — businesses below that figure are currently fully exempt. That threshold has already changed once since the mandate was first announced, which is the clearest evidence that a business should verify its current obligation directly rather than assume a figure it read months ago still holds.
The RM10,000 individual-invoice rule
Effective 1 January 2026, individual e-invoices became mandatory for transactions above RM10,000, and consolidated invoices — batching multiple transactions into one submission — are no longer permitted at that value. This is the rule that most affects businesses with a high volume of smaller transactions who had been relying on consolidation to reduce submission overhead.
What actually happens if a deadline is missed
This is genuinely a compliance question for LHDN or a tax advisor, not something to take from a vendor's blog post — the honest answer depends on specifics (how late, what volume, whether it's a first instance) that a general guide can't responsibly generalise. What's consistent advice regardless of specifics: the lead time to get a proper integration built and validated (8–14 weeks for a direct API integration, per our MyInvois integration guide) means the moment to start is before the deadline is close, not after.

Questions
Is my business exempt from e-invoicing?
Only if annual turnover is below RM1,000,000, per the threshold in force from 1 January 2026 — and that threshold has changed once already, so confirm current status with LHDN or your accountant rather than assuming.
Do I need e-invoicing if I only invoice other Malaysian businesses, not consumers?
The mandate applies to B2B, B2C and B2G transactions alike, with only narrow exemptions — this isn't limited to consumer-facing businesses.
What's the difference between the phase deadline and the relaxation period?
The phase deadline is when the obligation starts for that turnover band. The relaxation period that follows (typically around six months) is where LHDN eases enforcement while businesses transition — it softens how early non-compliance is treated, it doesn't move the start date.
