An initial trade name registration shall expire on September 1 of the second calendar year after the calendar year in which the initial registration occurred (for example, a trade name registration that occurred on August 15, 2015, would expire on September 1, 2017).
Except as provided in Subsection 8902.3, each renewal of a trade name registration shall expire two (2) years after the expiration date of the registration being renewed.
If a person has an existing trade name registration on October 1, 2015, the first renewal of that trade name registration after October 1, 2015 shall expire on September 1 of the second calendar year after the calendar year in which the initial registration occurred (for example, a trade name registration that occurred on August 15, 2015, would expire on September 1, 2017).
