The tax commissioner shall administer sections 5711.01 to 5711.36 of the Revised Code, which are laws which he is required to administer within the meaning of sections 5703.19 to 5703.37, 5703.39, 5703.41, and 5703.45 of the Revised Code. He may adopt and promulgate rules not inconsistent with sections 5711.01 to 5711.36 of the Revised Code, so that all taxable property shall be listed and assessed for taxation. The commissioner shall prescribe the forms of all blank returns consistently with such sections, and no return shall be made or accepted except on the proper prescribed form. Such rules and the forms prescribed may be varied to meet differing local conditions in the counties, but in prescribing such forms the commissioner shall be governed by the following requirements:
The enumeration in sections 5711.01 to 5711.36 of the Revised Code, of facts required to be stated in a return, and questions required to be asked, is not exclusive, but the commissioner may propound any other question in the forms of returns prescribed by him, the answer to which is relevant and material for the purpose of enabling the commissioner, pursuant to Title LVII of the Revised Code, to assess the taxable property of the taxpayer making the return, or that of any other taxpayer, or to administer any of the laws relating to taxation. Each question so propounded shall be answered specifically, and no return shall be accepted by the county auditor until full disclosure has been made as required by such blanks.
