(a) Whenever the tax assessor, county revenue commissioner, or other assessing official shall discover that any property, including any improvements on real estate assessed as vacant property, has escaped taxation in any assessment within five years next preceding the current year, he shall list, return, and value said property for assessment for the years during which same has escaped taxation and shall also endorse on such returns the year or years for which the property has escaped taxation and, except as provided in subsection (b) hereinafter, the accrual of a penalty of 10 percent of the taxes assessed thereon for each year.

(b) Any taxpayer who escaped assessment of tangible personal property for taxable years ending on or before September 30, 1988 shall not have accrued to his account the 10 percent penalty, provided:

(1) He files a proper tax return and assesses such property not later than June 30, 1989;

(2) He makes or agrees to be subject to an escape assessment for the tax year ending September 30, 1988; and

(3) He pays the tax due on such escape assessment without any penalty not later than June 30, 1989.

(c) Any taxpayer who fulfills the requirements of subsection (b) of this section to avoid penalty, shall not be liable for any unpaid ad valorem tax on the tangible personal property so assessed for the tax years ending on or before September 30, 1987.

(d) The assessing official shall give notice of an escape assessment by certified or registered mail, return receipt requested, to the owner or to the agent or attorney of such owner, notifying such person to appear before the assessing official in person, or by agent or attorney, within 20 days after such notice is given, if there is an objection to the assessment, and notifying such person that if no objection is made said assessment will be made final on the twentieth day after the mailing of such notice of escape assessment. If on the date set for hearing such objection the person against whom the assessment is made fails to appear or if in the opinion of the assessing official the assessment should not be changed and the assessment is proper, then the assessing official shall make the assessment final. The property owner, if he has filed objection to such assessment, may appeal from the assessment to the circuit court of the county in which the property is located within 30 days after such assessment becomes final, by giving notice in writing to the assessing official and by filing a copy of such notice with the clerk of the circuit court and giving bond to be approved by and filed with the clerk of the circuit court to cover costs, and thereafter such case shall be tried as other tax cases appealed to the circuit court from the board of equalization. The taxpayer or the state shall have the right to demand a trial by jury by filing a written demand therefor, within 10 days after the appeal is taken.

(e) Whenever any escape assessment is made final the taxes shall immediately become due, and the assessor, deputy assessor, or other assessing official shall forthwith certify the assessment to the tax collector, or other collecting official, who shall forthwith collect same, unless at the time of taking the appeal the taxpayer has executed a supersedeas bond with sufficient sureties to be approved by the clerk of the circuit court in double the amount of the taxes, payable to the State of Alabama, conditioned to pay all taxes, interest, and costs due the state, county, or any agency or subdivision thereof.
