9and granting rule-making authority.
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% of the formula and the property and payroll factors
each represent 25% 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 this bill, 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. The property
and payroll factors will be decreased, and eventually phased out, over four years as
the sales factor is increased and becomes the only factor. Beginning on January 1,
2008, the premium factor will be the only factor used to attribute a portion of an
insurance company's income to this state. The payroll factor will be decreased, and
eventually phased out, over four years as the premium factor is increased and
becomes the only factor.
Under current law, the income of an electric or gas utility is apportioned by
rules established by the Department of Revenue (DOR). Under the bill, for taxable
years beginning after December 31, 2005, and before January 1, 2008, the income of
an electric or gas utility is apportioned in the same manner as the income of a
corporation under the bill. Beginning on January 1, 2008, the sales factor will be the
only factor used to attribute a portion of the income of an electric or gas utility to this
state.
Under current law, the income of a financial organization is apportioned, for
corporate income tax and franchise tax purposes, by rules established by DOR.
Under the bill, for taxable years beginning after December 31, 2005, and before
January 1, 2008, the income of a financial organization is apportioned by multiplying
that income by a fraction that includes a sales factor representing more than 50% of
the fraction, as determined by rule by DOR. For taxable years beginning after
December 31, 2007, the income of a financial organization is apportioned by using
a sales factor, as determined by DOR.
Under current law and under the bill, the income of air carriers and pipeline
companies is apportioned by rules established by DOR.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.

7income attributable to Wisconsin may be determined by an allocation and separate

1accounting thereof, when the business of such nonresident individual or nonresident
2estate or trust within the state is not an integral part of a unitary business, but the
