(f) Before a county auditor terminates a deduction under this article, the county auditor shall give to the person claiming the deduction written notice that states the county auditor's intention to terminate the deduction and the county auditor's reason for terminating the deduction.  The county auditor may send the notice to the taxpayer claiming the deduction by first class mail or by electronic mail.  A notice issued under this subsection is not appealable under IC 6-1.1-15.  However, after a deduction is terminated by a county auditor, the taxpayer may appeal the county auditor's action under IC 6-1.1-15.
