(a) The assessment of property, as the same appears on the tax roll last prepared, shall, after it has been corrected, amended and revised, as herein provided for, constitute the assessment roll for the current calendar year. As soon after January 1st of each year as possible, and not later than May 31st, the Tax Assessor shall fill out an assessment schedule showing in detail each separate piece of real property and improvements thereon, subject to taxation and belonging, on January 1st, to each taxable person whose property, in the opinion of the Tax Assessor should be revalued or reassessed for the purpose of taxation, or the revaluation of which has been requested by the owner thereof or by the government of the United States Virgin Islands, or by any property owner. The assessment roll shall be open to public inspection at any time.
(b) The Tax Assessor may deliver such blank schedule or schedules, to which may be attached such interrogatories as he deems necessary in order to secure discovery of taxable property and its value, to any taxable person or to any adult member of his household or business establishment, and require said taxable person to issue and make the proper receipt for such schedule and return the same to him, properly filled out, within a period not to exceed ten days, and the taxable person shall make upon said schedule or schedules, a complete return and full valuation of all the real property owned, held or possessed by him and liable to taxation, and return the same to said Tax Assessor within the period of time appointed. Every partnership, concern, trustee, administrator, guardian, agent and every person having any manner of title, either legal or equitable, or having possession of, holding or claiming in any manner anything required to be returned in the schedule shall be held subject to the provisions of this subtitle and shall make return upon said schedule as provided in this section.
(c) Whenever property is owned, held or possessed by more than one person as administrator, executor, trustee, or in any other fiduciary or representative capacity, any one of them may make the oath required by section 2406 of this title. Every schedule of partnership property shall be sworn to by at least one of the partners, and every schedule of corporate property shall be sworn to by the president, director or local agent. Every schedule of a limited liability company shall be sworn to by a member or manager. The Tax Assessor, however, shall not be bound in any manner by the list of property or the value placed thereon as thus returned by a taxpayer, but shall proceed upon the information as he may be able to obtain, to assess the property at its actual value, according to his best information.
