Indiana Governor Mike Pence has signed several bills that significantly change elements of the Indiana income and sales tax laws.

Intercompany Expense Addbacks

Under current law, intercompany interest expense is required to be added back to Indiana adjusted gross income only in situations where the intercompany interest was the result of transactions involving intangible assets. Under the recent legislation, all intercompany interest, not just interest related to intangibles, must be added back to Indiana adjusted gross...
