Sri Lanka Launches National E-Invoicing System to Modernize Tax Infrastructure

As part of a broader initiative to reach its 2030 digital economy targets, Sri Lanka has initiated the implementation of a national electronic invoicing framework. This project, managed by the Department of Inland Revenue, is designed to modernize the country’s tax administration, enhance financial transparency, and proactively address tax evasion. The system will be integrated directly with the existing Revenue Administration Management Information System (RAMIS) to ensure a unified digital tax environment.

Technical Architecture and API Integration

The Inland Revenue authorities have identified a secure Web Application Programming Interface (Web API) as the foundation for this transition. This approach facilitates a seamless digital connection between a taxpayer’s internal ERP systems and the RAMIS platform.

Phased Implementation Roadmap

The rollout of the e-invoicing mandate is structured into several stages:

• The implementation will begin with the pilot phase involving a group of selected taxpayers who have already updated their ERP systems to support API connectivity. Full deployment of this initial phase is anticipated by the end of 2025.
• Following the pilot, the mandate will be extended to encompass selected export-oriented businesses.
• The system will subsequently become mandatory for all VAT-registered businesses across the country.
• The final stage of the reform will mandate e-invoicing for B2C transactions via Point-of-Sale (POS) systems. This will enable real-time transaction recording and significantly improve VAT oversight through a centralized web-based platform.
