* State has adopted substantial portions of the UDITPA.
(1) A 3-factor formula is used for corporations not subject to the corporation business franchise tax.
(2) Corporations using this formula must release financial data to the Legislative Budget Committee,
otherwise use double weighted sales.
(3) State is phasing in a single sales factor. Weightings will change each year until 100% sales factor
in 2011 for Indiana, and 2013 for Minnesota.
(4) Taxpayers are allowed only 40% of the reduced taxes from a single sales factor (60% in 2009)
