How much revenue would full “combined reporting” generate in Tennessee?
A. Because corporations’ tax returns are treated as confidential, proprietary information, it is difficult to know with certainty how much revenue would be generated by “combined reporting” in Tennessee. The most detailed study on revenue generated through “combined reporting”, prepared by the Pennsylvania Department of Revenue, received an award for best research by a state revenue department from the Federation of Tax Administrators. That study found that “combined reporting” would increase business income tax revenue by 24%. Based on the following table, TFT estimates additional business income tax revenue in the range of 12-25%. Tennessee’s projected business income tax revenue for 2007 is around $1 Billion. This figure suggests that “combined reporting” could result in additional revenue between $120 and $250 Million.
