A. The appropriate county, city or town assessing officer shall make and maintain an inventory and assessment of all tax-exempt real property and all such property immune from real estate taxation within his county, city or town, excluding streets, highways and other roadways. Such official shall identify such property by a general site description indicating the owner thereof and report such information on the land book along with an assessment of the fair market value of such property, the total assessed valuation for each type of exemption and a computation of total tax which would be due if such property were not exempt. A total of such assessed valuations and a computation of the percentage such exempt and immune property represents in relation to all property assessed within the county, city or town shall be published annually by such local assessing officer and a copy thereof shall be filed with the Department of Taxation on forms prescribed by the Department. All costs incurred pursuant to this section shall be borne by the county, city or town.
B. The appropriate county, city or town assessing officer shall also cause to be published, on an annual basis, at the same time and in the same publication, or in the same manner, as notice of the local real estate tax rates is published or otherwise posted, a statement indicating the aggregate assessed value of all real property exempted from taxation under §§ 58.1-3607 and 58.1-3608, and Articles 3, 4 and 5 of Chapter 36 of this title, and the total reduction in tax revenues resulting from such exemptions.
