Am I liable for any criminal prosecution [arrest/imprisonment, etc.] if I don’t file my Income-tax return, even though my income is taxable?

Ans. Non-payment of tax attracts interests, penalty and prosecution. The prosecution can lead to rigorous imprisonment from 3 months to 2 years (when the tax sought to be evaded exceeds Rs. 25,00,000 the punishment could be 6 months to 7 years).
