Centralized Processing Centre [CPC] & It’s Role

The Government of India (GOI) on the recommendations of the Business Process Re-engineering Committee (BPR Committee) approved (February 2009) the establishment of a Centralised Processing Centre.

The Income Tax Department has been granted the authority to establish a Centralized Processing Center (CPC) dedicated to handling tax returns. The primary goal of this center,  is to determine the tax liability and process refunds for taxpayers.

Notably, the CPC autonomously processes returns submitted by assesses without any involvement from the taxpayer or jurisdictional officers. This streamlined approach aims to ensure swift and accurate processing of returns while providing timely information to taxpayers.

Upon the completion of the processing phase, the department issues an intimation to the taxpayer. This intimation serves as a communication channel, allowing the taxpayer an opportunity to respond to any adjustments made by the CPC. It is crucial for the taxpayer to address these adjustments within 30 days of receiving the intimation.
