Singapore continues to lead Asia’s digital transformation journey with two groundbreaking regulatory developments that are reshaping how businesses operate in the city-state. The mandatory implementation of INVOICENOW for e-invoicing and the introduction of the Corporate Services Providers Act (CSP Act) 2024 represent significant milestones in Singapore’s commitment to digitalisation, transparency, and anti-money laundering compliance.
INVOICENOW: Singapore’s Nationwide E-Invoicing Revolution
Singapore’s INVOICENOW system, built on the internationally recognised Peppol (Pan-European Public Procurement Online) standard, is transforming how businesses handle invoicing and GST compliance. The Inland Revenue Authority of Singapore (IRAS) has reconfirmed 7 March 2025 the phased voluntary introduction of e-invoice data reporting via InvoiceNow, marking a crucial step toward full digitalisation of business transactions.
Phased Implementation Timeline
The GST InvoiceNow Requirement follows a carefully structured rollout schedule designed to give businesses adequate preparation time:
Phase 1: Voluntary Adoption
- May 2025: Voluntary adoption by GST-registered businesses
- Initial testing phase for early adopters
Phase 2: Mandatory Implementation
- November 1, 2025: Newly incorporated businesses that voluntarily register for GST
- April 1, 2026: All new voluntary GST registrants
The phased approach ensures that accounting firms in Singapore and businesses have sufficient time to adapt their systems and processes. This gradual implementation recognises the complexity of digital transformation while maintaining Singapore’s reputation for business-friendly policies.
Key Benefits for Businesses
INVOICENOW offers substantial advantages for companies seeking efficient accounting services in Singapore:
- Streamlined GST Compliance: Direct transmission of invoice data to IRAS eliminates manual filing processes
- Reduced Administrative Burden: Automated data capture reduces human error and processing time
- Enhanced Cash Flow Management: Faster invoice processing and approval cycles
- Improved Audit Trail: Complete digital records enhance transparency and compliance
- Cost Savings: Long-term reduction in administrative costs and paper-based processes
Support for New Businesses
InvoiceNow Accelerate was launched in April 2024 to provide newly incorporated businesses a head-start in their digitalisation journey with one year of free InvoiceNow services. This initiative demonstrates Singapore’s commitment to supporting entrepreneurship while ensuring compliance readiness from day one. Here is the IRAS e-Tax Guide
Corporate Services Providers Act 2024: Strengthening Singapore’s Financial Integrity
The Singapore Corporate Service Providers Act 2024 (“CSP Act”), effective 9 June 2025, introduces critical compliance requirements for businesses using corporate services in Singapore.
