The tax administrators of the States of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, Oklahoma, South Dakota, and Wisconsin realize that by their geographical proximity to each other and the similarity of their economies, these thirteen states share the same interests in tax administration.  As a result of these shared interest, in 1961,  MSATA was formed for the purpose and importance of their active participation in the affairs of the Federation of Tax Administrators.
