7(3m) of the statutes; relating to: the repeal of single sales factor apportionment
8of corporate income.
Analysis by the Legislative Reference Bureau
Under current law, when computing corporate income taxes and franchise
taxes, a formula is used to attribute a portion of a corporation's income to this state.
The formula has three factors: a sales factor, a property factor, and a payroll factor.
The sales factor represents 50 percent of the formula and the property and payroll
factors each represent 25 percent of the formula. When computing income taxes and
franchise taxes for an insurance company, a formula with a premium factor and a
payroll factor is used to attribute a portion of an insurance company's income to this
state. Under current law, beginning on January 1, 2008, the sales factor will be the
only factor used to attribute a portion of a corporation's income to this state and the

premium factor will be the only factor used to attribute a portion of an insurance
company's income to this state.
Under this bill, the formula for attributing a portion of a corporation's income
to this state will continue to have a sales factor, a property factor, and a payroll factor,
rather than just a sales factor. Under this bill, the formula for attributing a portion
of an insurance company's income to this state will continue to have a premium factor
and a payroll factor, rather than just a premium factor.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
The people of the state of Wisconsin, represented in senate and assembly, do
enact as follows:
