Commercial training or coaching taxability clarified: all coaching centres liable as taxable service, irrespective of trust status or profit motive. Any service provided by a commercial training or coaching centre is taxable; the statutory definition includes any centre imparting training or coaching for consideration irrespective of registration or profit motive. The definition covers instruction to impart skill, knowledge or lessons on any subject except sports and expressly includes coaching and tutorial classes. Administrative circulars consolidate prior technical guidance on scope, valuation, export, and exemptions.
