E-Invoice Requirements for Architect / Architecture Firm in Malaysia (2026)
Malaysia's MyInvois e-invoicing mandate is transforming how architect / architecture firm businesses issue and receive invoices. Whether you're already mandated or preparing for Phase 4 (January 2026), this guide gives you the clear, practical steps to get compliant.
Does this apply to your Architect / Architecture Firm business?
Phase 4 of Malaysia's MyInvois mandate covers all businesses with annual turnover above RM 1 million, effective 1 January 2026 with a grace period until 30 June 2026. Below the RM 1 million threshold, compliance is currently voluntary — but collecting the required data now puts you ahead.
Why Architect / Architecture Firm businesses need to act now
Architecture firms typically bill property developers and government bodies who are mandated under earlier MyInvois phases — making compliant e-invoicing essential to receive payment without delay.
MSIC Code for Architect / Architecture Firm
LHDN requires your MSIC (Malaysia Standard Industrial Classification) code on every e-invoice submission. For architect / architecture firm: 71111 (Architectural Activities).
Verify your exact MSIC code at dosm.gov.my or the LHDN MyInvois portal.

Frequently asked questions for Architect / Architecture Firm in Malaysia
When do architects in Malaysia need to comply with e-invoicing?
Architecture firms with annual turnover above RM 1 million must comply from 1 January 2026. Most established practices and larger firms will meet this threshold given project-based billing amounts.
Are architectural services subject to SST?
Yes — architectural services are subject to Service Tax at 8% if the firm's revenue exceeds the RM 500,000 registration threshold. Each invoice must clearly show the service tax registration number, rate, and amount.
How do architects handle progress billing under MyInvois?
Architectural fees are typically billed in stages (e.g., schematic design, design development, construction documents, site supervision). Each stage billing is a separate e-invoice submitted to LHDN, with the project reference and stage description clearly stated.
What MSIC code applies to architecture practices?
71111 — Architectural Activities. If your practice also provides engineering or related technical consulting, those services may require separate classification codes on mixed invoices.
