Analysis by the Legislative Reference Bureau
Corporate rate structure
Under current law, the rate for the income tax and franchise tax imposed on cor
porations, including tax-option corporations and insurers, is 7.9%. This bill esta
blishes a graduated rate structure, the highest rate of which is 7.9%.
Corporate minimum tax
This bill creates an alternative minimum tax that is based on the federal mini
mum tax; that is imposed on corporations, including tax-option corporations and in
surers; and that is due if it results in greater liability than the regular corporate in
come tax or franchise tax.
Capital gains
This bill also changes current law by including one-half of the 60% capital gains
exclusion and the net capital gains on certain small business stock as a tax prefer
ence item in the calculation of the alternative minimum tax that applies to individu
als. Generally, tax preference items are benefits received in the form of deductions,
lower tax rates and exclusions.

For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
