Information return obligation requires furnishing prescribed transactional data; defective returns may be treated as not furnished. A wide range of persons and authorities maintaining records or periodic returns of registration, accounts, tax payments, transactional details, bank-account activity, electricity consumption, or property transactions must furnish an information return in the prescribed form, manner, period and to the prescribed authority. The Commissioner or an authorised officer may declare a return defective, require rectification within thirty days or longer on application, and if not rectified the return is to be treated as not furnished; failure to furnish may also attract a notice requiring submission within a period not exceeding ninety days.
