What is Income Tax?
Income Tax is a direct tax levied by the Government of India on the income earned by individuals, Hindu Undivided Families (HUFs), firms, companies, and other entities during a financial year (April-March).
The Income Tax Department under the Central Board of Direct Taxes (CBDT) administers and enforces tax laws in India.
