I have pension and professional income as a consultant, should I file ITR under Section 44ADA to reduce income tax?

ET Wealth Reader's Query: After retiring from a public sector bank, I transitioned to teaching at various MBA institutes in Mumbai and also work as a consultant with banks and related organisations. I have been filing my income-tax returns in the standard manner. Some friends have suggested that I should, instead, file my returns under Section 44ADA of the Income-tax Act to potentially reduce my tax liability.
