Information return obligation requires prescribed entities to furnish transaction records and allows rectification and enforcement notices. Obligation to furnish information return applies to prescribed persons who maintain records or returns of transactions, tax payments, bank accounts, electricity consumption, or transfers of goods or property; such returns must be submitted in the prescribed form, manner, period and to the prescribed authority. If the Commissioner or an authorised officer finds an information return defective, the person is entitled to rectify within thirty days or a further allowed period, failing which the return is treated as not furnished and the Act's provisions apply; the authority may also serve a notice requiring furnishing within a specified period.
