Description of Occupational Work

This class series uses four levels in the Administrative Services occupational group, Fiscal Services occupational series. Tax auditing involves auditing corporate, business and individual tax returns to determine the accuracy of self-assessed tax payments, arranging for the collection of delinquent taxes and ensuring compliance with tax laws. Representative types of taxes audited include but are not limited to corporate, business and personal income, withholding, licensing, fiduciary, realty transfer, gross receipt, motor fuel, cigarette and bankruptcy. 

Note: This career ladder series incorporates levels I and II.  Based on the level of work applicable to the employing agency and functional area, positions can be allocated up to level II.  The I level is to provide entry for hiring new employees into the class series but does not preclude hiring new employees at higher levels.  Employees may be promoted through the career ladder in accordance with minimum qualifications and promotional standards. Promotional standards, a selection document under separate cover, sets forth the criteria that defines and describes the requirements that must be met at each level.  Advancement of employees through the career ladder is dependent on an agency's/department's operational needs and distribution of work.
The Tax Auditor III and Tax Auditor Supervisor levels, although not part of the career ladder, provide competitive opportunity for movement of employees.
