What is Phase 4? A Quick Refresher
- Started 1 January 2026, Phase 4 mandates that businesses with annual sales or revenue up to RM5 million adopt e-invoicing processes. (hasil.gov.my)
- However, entities meeting exemption criteria—turnover under RM3 million and other conditions—are currently exempt, with no penalties in place during the transition. (hasil.gov.my)
- Transition/concession period runs through 31 December 2027. During this time, businesses may use simplified e-invoice formats or consolidated self-billing where allowed. (hasil.gov.my)
Immediate Steps for Businesses in Phase 4 Bracket
- Assess your revenue band: Are you likely between RM3 million to RM5 million? If yes, you fall under mandatory compliance in Phase 4.
- Understand exemption conditions: Not just revenue—ownership structure and related parties matter. If you fail any criteria, you must comply. (hasil.gov.my)
- Upgrade or select appropriate e-invoicing system: Options include MyInvois portal, MyInvois e-POS, or certified third-party providers.
- Train accounting and sales teams to issue valid e-invoices, document transactions correctly, capture buyer’s Tax Identification Number (TIN), etc.
- Use transition period wisely: No penalties yet if you comply under relaxed guidelines. Experiment, pilot, and refine practices.
Common Pitfalls to Avoid
- Relying on bundled invoices when individual ones are required (especially when transactions exceed set amounts like RM10,000 in some sectors).
- Not verifying whether your business is exempt due to related entities or shareholders exceeding thresholds.
- Missing deadline for adoption if exemption is lost (e.g., exceeding RM1 million and not meeting exemption criteria).
Case Example: Construction Supply Firm
Suppose ABC Trading supplies building materials and has RM4.5 million in annual sales. Because they exceed RM3 million, they are not exempt. Starting Jan 2026, they should have set up e-invoice issuance workflows—choosing whether to issue self-billed, consolidated, or detailed invoices, depending on sector rules. If they delay past Dec 2027 without complaint-worthy compliance, HASiL could start enforcing penalties.
Final Tips for Smooth Transition
- Regularly monitor HASiL notices—technical/e-invoice threshold changes may still happen.
- Document all changes, make policy for staff, and keep systems updated.
- Consider voluntary adoption even if exempt—digitization helps in due diligence, auditing, and future readiness.
