Tamil Nadu plans Single Window 3.0 for faster business clearance

Tamil Nadu plans a Single Window Portal 3.0, being developed by Guidance Tamil Nadu and proposed for launch by December 2026. Departments could raise only one consolidated query per application, and the approval clock would pause rather than restart from Day 1. Other features include parallel processing of independent approvals, reuse of government-held documents, and risk-based processing with self-certification for low-risk applications, aimed at cutting reliance on separate departmental portals.
