Records may be required of taxpayer.

Whenever the department deems it necessary that a person subject to an income or franchise tax should keep records to show whether or not the person is liable to tax, the department may serve notice upon the person and require such records to be kept as will include the entire net income of the person and will enable the department to compute the taxable income. The department may require any person who keeps records in machine-readable form for federal income tax purposes to keep those records in the same form for purposes of the taxes under this chapter.
