In April 2026, LHDN extended the penalty-free relaxation for Phase 4 businesses (RM1M–5M turnover) by 12 months, to December 31, 2027. Full enforcement — fines of RM200 to RM20,000 per non-compliant invoice — begins January 1, 2028. The extension is breathing room to get compliant, not a reason to delay.
What to do
1
Use 2026-2027 to test and stabilize your MyInvois workflow while mistakes are penalty-free
2
Train whoever handles billing on validation rejections — rejected invoices delay payment even without fines
Risk if ignored: From January 1, 2028: RM200–RM20,000 per non-compliant invoice, potential prosecution under the Income Tax Act.
