Widening of service tax base expands taxable services and adjusts thresholds, definitions, exemptions and compliance rules. The Finance Bill expands the service tax base and adjusts thresholds: it raises exemption and registration limits for small providers, consolidates and newly specifies taxable services-notably telecommunication, mining, renting of immovable property for business, works contract services (with valuation rules and optional composition), content development for telecom/advertising/internet, non-banking asset/fund management, and design services-and amends definitions, exclusions and procedural rules. New targeted exemptions (RWAs, incubators/incubatees, CRO clinical trials, and digital cinema delivery) and amendments to CENVAT, export rules, registration, return revision and reverse-charge mechanisms are also provided.
