Field audit.
(a)#
Whenever the department deems it advisable to verify any return directly from the books and records of any person, or from any other sources of information, the department may direct any return to be so verified.
(b)#
For the purpose of ascertaining the correctness of any return or for the purpose of making a determination of the taxable income of any person, the department may examine or cause to be examined by any agent or representative designated by it, any books, papers, records or memoranda bearing on the income of the person, and may require the production of the books, papers, records or memoranda, and require the attendance of any person having knowledge in the premises, and may take testimony and require proof material for its information. Upon such information as it may be able to discover, the department shall determine the true amount of income received during the year or years under investigation.
(c)#
If it appears upon such investigation that a person has been over or under assessed, or that no assessment has been made when one should have been made, the department shall make a correct assessment in the manner provided in this chapter.
