Annual Report:
The CIC prepares an annual report that provides an overview of its activities, achievements, challenges, and recommendations. This report is an important document that assesses the progress made in implementing the RTI Act and highlights any issues or areas for improvement.

Submission of the Annual Report:
The annual report of the CIC is submitted to the Central Government. Here's why:

1. Accountability: The CIC is accountable to the Central Government as it is a statutory body established by the government. Submitting the annual report to the Central Government ensures transparency and accountability in the functioning of the Commission.

2. Government Oversight: The Central Government has the authority to oversee the activities of the CIC. By submitting the annual report, the Commission provides the government with insights into its functioning, challenges faced, and recommendations for improvement.

By submitting the report to the Central Government, the Commission provides information regarding its budgetary requirements, which helps the government in allocating funds for its functioning.
