The document discusses the Aayakar Seva Kendra (ASK), which is the Income Tax department's flagship project for integrated service delivery and a single point of contact for taxpayers. The ASK represents a single window system for registration of taxpayer applications and returns. It issues unique acknowledgement numbers for applications and tracks requests throughout their lifecycle. The ASK reflects the department's shift from an enforcement-only agency to also being a service provider, in line with recommendations to prioritize taxpayer services and make the department more customer-oriented.
