In this paragraph, “wholly exempt income”, for corporations subject to franchise or income taxes, includes amounts received from affiliated or subsidiary corporations for interest, dividends or capital gains that, because of the degree of common
ownership, control or management between the payor and payee,
are not subject to taxes under this chapter. In this paragraph,
“wholly exempt income”, for corporations subject to income taxation under this chapter, also includes interest on obligations of
the United States. In this paragraph, “wholly exempt income”
does not include income excludable, not recognized, exempt or
deductible under specific provisions of this chapter. If any expense or amount otherwise deductible is indirectly related both to
wholly exempt income or loss and to other income or loss, a reasonable proportion of the expense or amount shall be allocated to
each type of income or loss, in light of all the facts and circumstances. This paragraph does not apply to the exclusion under

3. Section 71.28 (3).
4. Section 71.28 (4).

under s. 71.28 (4) instead of to federal credits and federal net operating losses.

this chapter.

of unrelated business taxable income in section 512, and replaced
by the treatment of exemptions under sub. (1).

that are exempt from tax under this chapter.
(u) Section 1017 (relating to adjustments to basis because of
discharge of indebtedness) is modified to reflect the modification
under par. (c).
(v) Section 1033 is modified so that it does not apply to involuntary conversions of property in this state that produces nonbusiness income and that is replaced with similar property outside this state and to involuntary conversions of property in this
state that produces business income and that is replaced with
property outside this state if at the time of replacement the taxpayer is not subject to tax under this chapter.
(vm) 1. For taxable years beginning after December 31,
2019, section 1400Z-2 (relating to capital gains invested in opportunity zones) is modified so that an increase in basis is twice
the amount determined under section 1400Z-2 (b) (2) (B) (iii) for
an investment held in a Wisconsin qualified opportunity fund for
at least 5 years or under section 1400Z-2 (b) (2) (B) (iv) for an investment held in a Wisconsin qualified opportunity fund for at
least 7 years. In this subdivision, “Wisconsin qualified opportunity fund” has the meaning given in s. 71.05 (25m) (a) 2.

fund shall annually certify to each investor and the department

offset against its Wisconsin net business income any Wisconsin
net business loss incurred in any of the 20 immediately preceding
taxable years, if the corporation was subject to taxation under this
chapter in the taxable year in which the loss was incurred, to the
extent not offset by other items of Wisconsin income in the loss
year and by Wisconsin net business income of any year between
the loss year and the taxable year for which an offset is claimed.
For purposes of this subsection, Wisconsin net business income
or loss shall consist of all the income attributable to the operation
of a trade or business in this state, less the business expenses allowed as deductions in computing net income. The Wisconsin
net business income or loss of corporations engaged in business
within and without the state shall be determined under s. 71.25
(6) and (10) to (12). Nonapportionable losses having a Wisconsin situs under s. 71.25 (5) (b) shall be included in Wisconsin net
business loss; and nonapportionable income having a Wisconsin
situs under s. 71.25 (5) (b), whether taxable or exempt, shall be
included in other items of Wisconsin income and Wisconsin net
business income for purposes of this subsection.
