rolls - Assessments - Arrearages - Taxing during current year.

A. If any real, personal, railroad, air carrier or public

service corporation property is omitted in the assessment of any

prior year or years, and the property thereby escapes just and

proper taxation, at any time and as soon as such omission is

discovered, the county assessor or the county board of equalization,

or the State Board of Equalization in the case of public service

corporation property or railroad and air carrier property, whose

duty it is to assess the class of property which has been omitted,

shall at any time cause such property to be entered on the

assessment rolls and tax rolls for the year or years omitted, not to

exceed the last fifteen (15) years as to real property and the last

three (3) years as to personal property, and shall, after reasonable

notice to the parties affected, in order that they be heard, assess

such omitted property for said periods and cause to be extended

against the same on the tax rolls for the current year all arrearage

of taxes properly accruing against it, including therein interest

thereon at the rate of twelve percent (12%) per annum from the time

such tax should have become delinquent.

B. If any tax on property subject to taxation is prevented from

being collected for any year or years by reason of any erroneous

proceedings, or failure to give notice, or otherwise, the amount of

such tax which such property should have paid or should have been

paid thereon shall be added to the tax on such property for the

current year, and if for want of sufficient time or for any cause

such assessment cannot be entered, and the tax thereon extended on

the tax rolls for the current year, the same shall be done the

following year.
