Interstate Tax Corporation, now in its 32nd year of doing business, continues to train and update state tax practitioners on how to properly navigate the interstate tax system. With Caryl Nackenson-Sheiber at its helm, the company has dedicated itself to the education of multistate tax professionals in industry, consulting and government through four seminars held in the spring and fall of each year and its publication, Interstate Tax Insights.

Interstate Tax Corporation seminars are known throughout the industry for their practicality, all-star speakers who know how to entertain as well as educate, and up-to-the-minute information, all of which are extremely useful to the state tax professional. Unlike the larger symposiums, ITC seminars range in size from 10-30 participants, allowing the attendees to feel comfortable raising questions, establish peer contacts, and absorb the material, all in an intimate, yet professional environment. This effective learning environment has been maintained successfully in the live on-line seminars we have offered for the last few years.

Caryl Nackenson-Sheiber is the Editor-in-Chief of Interstate Tax Insights, the Chairperson of, and one of the primary speakers at, ITC’s multistate tax seminars, and an attorney specializing in state taxation of multistate business. Prior to her tenure with Interstate Tax Corporation, Ms. Sheiber was, for nine years, the Managing Editor of Interstate Tax Report, the predecessor to Interstate Tax Insights. She received her B.A. in English magna cum laude from the State University of New York at Albany and J.D. from St. John’s University School of Law.
