Explanation:

Corporation tax is a direct tax imposed on the net income or profit that enterprises make from their businesses.

• Companies, both public and privately registered in India under the Companies Act 1956, are liable to pay corporation tax.
• This tax is levied at a specific rate according to the provisions of the Income Tax Act, 1961.
• In September 2019, India slashed corporate tax rates to 22% from 30% for existing companies and to 15% from 25% for new manufacturing companies.
• Including a surcharge and cess, the effective tax rate for existing companies now stands at 25.17%, down from 35%.

Hence both statements 2&3 are correct.
