Notwithstanding the provisions of section 621.050 to the contrary, an additional assessment may be appealed to the administrative hearing commission within sixty days after the date the assessment is delivered in person or is sent by certified mail, whichever is earlier.

2. Within sixty days after the date on which an additional assessment is delivered in person or is sent by certified mail, whichever is earlier, the taxpayer may request an informal review of the assessment by the director of revenue.

3. The taxpayer may request and the director may enter into a payment agreement with any taxpayer against which an assessment has been made, if the director determines that such agreement is in the best interest of the state.
