Section 5. The Illinois Income Tax Act is amended by
changing Section 203 as follows:
(35 ILCS 5/203) (from Ch. 120, par. 2-203)
Sec. 203. Base income defined.
(a) Individuals.
(1) In general. In the case of an individual, base
income means an amount equal to the taxpayer's adjusted
gross income for the taxable year as modified by paragraph
(2).
(2) Modifications. The adjusted gross income referred
to in paragraph (1) shall be modified by adding thereto
the sum of the following amounts:
(A) An amount equal to all amounts paid or accrued
to the taxpayer as interest or dividends during the
taxable year to the extent excluded from gross income
in the computation of adjusted gross income, except
stock dividends of qualified public utilities

HB3580 - 2 - LRB103 05339 SPS 50358 b
described in Section 305(e) of the Internal Revenue
Code;
(B) An amount equal to the amount of tax imposed by
this Act to the extent deducted from gross income in
the computation of adjusted gross income for the
taxable year;
(C) An amount equal to the amount received during
the taxable year as a recovery or refund of real
property taxes paid with respect to the taxpayer's
principal residence under the Revenue Act of 1939 and
for which a deduction was previously taken under
subparagraph (L) of this paragraph (2) prior to July
1, 1991, the retrospective application date of Article
4 of Public Act 87-17. In the case of multi-unit or
multi-use structures and farm dwellings, the taxes on
the taxpayer's principal residence shall be that
portion of the total taxes for the entire property
which is attributable to such principal residence;
(D) An amount equal to the amount of the capital
gain deduction allowable under the Internal Revenue
Code, to the extent deducted from gross income in the
computation of adjusted gross income;
(D-5) An amount, to the extent not included in
adjusted gross income, equal to the amount of money
withdrawn by the taxpayer in the taxable year from a
medical care savings account and the interest earned

HB3580 - 3 - LRB103 05339 SPS 50358 b
on the account in the taxable year of a withdrawal
pursuant to subsection (b) of Section 20 of the
Medical Care Savings Account Act or subsection (b) of
Section 20 of the Medical Care Savings Account Act of
2000;
(D-10) For taxable years ending after December 31,
1997, an amount equal to any eligible remediation
costs that the individual deducted in computing
adjusted gross income and for which the individual
claims a credit under subsection (l) of Section 201;
(D-15) For taxable years 2001 and thereafter, an
amount equal to the bonus depreciation deduction taken
on the taxpayer's federal income tax return for the
taxable year under subsection (k) of Section 168 of
the Internal Revenue Code;
(D-16) If the taxpayer sells, transfers, abandons,
or otherwise disposes of property for which the
taxpayer was required in any taxable year to make an
addition modification under subparagraph (D-15), then
an amount equal to the aggregate amount of the
deductions taken in all taxable years under
subparagraph (Z) with respect to that property.
If the taxpayer continues to own property through
the last day of the last tax year for which a taxpayer
may claim a depreciation deduction for federal income
tax purposes a subtraction is allowed with respect to

HB3580 - 4 - LRB103 05339 SPS 50358 b
that property under subparagraph (Z) and for which the
taxpayer was allowed in any taxable year to make a
subtraction modification under subparagraph (Z), then
an amount equal to that subtraction modification.
The taxpayer is required to make the addition
modification under this subparagraph only once with
respect to any one piece of property;
(D-17) An amount equal to the amount otherwise
allowed as a deduction in computing base income for
interest paid, accrued, or incurred, directly or
indirectly, (i) for taxable years ending on or after
December 31, 2004, to a foreign person who would be a
member of the same unitary business group but for the
fact that foreign person's business activity outside
the United States is 80% or more of the foreign
person's total business activity and (ii) for taxable
years ending on or after December 31, 2008, to a person
who would be a member of the same unitary business
group but for the fact that the person is prohibited
under Section 1501(a)(27) from being included in the
unitary business group because he or she is ordinarily
required to apportion business income under different
subsections of Section 304. The addition modification
required by this subparagraph shall be reduced to the
extent that dividends were included in base income of
the unitary group for the same taxable year and

HB3580 - 5 - LRB103 05339 SPS 50358 b
received by the taxpayer or by a member of the
taxpayer's unitary business group (including amounts
included in gross income under Sections 951 through
964 of the Internal Revenue Code and amounts included
in gross income under Section 78 of the Internal
Revenue Code) with respect to the stock of the same
person to whom the interest was paid, accrued, or
incurred.
This paragraph shall not apply to the following:
(i) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary
reporting, to a tax on or measured by net income
with respect to such interest; or
(ii) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person if
the taxpayer can establish, based on a
preponderance of the evidence, both of the
following:
(a) the person, during the same taxable
year, paid, accrued, or incurred, the interest
to a person that is not a related member, and
(b) the transaction giving rise to the
interest expense between the taxpayer and the
person did not have as a principal purpose the

HB3580 - 6 - LRB103 05339 SPS 50358 b
avoidance of Illinois income tax, and is paid
pursuant to a contract or agreement that
reflects an arm's-length interest rate and
terms; or
(iii) the taxpayer can establish, based on
clear and convincing evidence, that the interest
paid, accrued, or incurred relates to a contract
or agreement entered into at arm's-length rates
and terms and the principal purpose for the
payment is not federal or Illinois tax avoidance;
or
(iv) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person if
the taxpayer establishes by clear and convincing
evidence that the adjustments are unreasonable; or
if the taxpayer and the Director agree in writing
to the application or use of an alternative method
of apportionment under Section 304(f).
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act
for any tax year beginning after the effective
date of this amendment provided such adjustment is
made pursuant to regulation adopted by the
Department and such regulations provide methods
and standards by which the Department will utilize

HB3580 - 7 - LRB103 05339 SPS 50358 b
its authority under Section 404 of this Act;
(D-18) An amount equal to the amount of intangible
expenses and costs otherwise allowed as a deduction in
computing base income, and that were paid, accrued, or
incurred, directly or indirectly, (i) for taxable
years ending on or after December 31, 2004, to a
foreign person who would be a member of the same
unitary business group but for the fact that the
foreign person's business activity outside the United
States is 80% or more of that person's total business
activity and (ii) for taxable years ending on or after
December 31, 2008, to a person who would be a member of
the same unitary business group but for the fact that
the person is prohibited under Section 1501(a)(27)
from being included in the unitary business group
because he or she is ordinarily required to apportion
business income under different subsections of Section
304. The addition modification required by this
subparagraph shall be reduced to the extent that
dividends were included in base income of the unitary
group for the same taxable year and received by the
taxpayer or by a member of the taxpayer's unitary
business group (including amounts included in gross
income under Sections 951 through 964 of the Internal
Revenue Code and amounts included in gross income
under Section 78 of the Internal Revenue Code) with

HB3580 - 8 - LRB103 05339 SPS 50358 b
respect to the stock of the same person to whom the
intangible expenses and costs were directly or
indirectly paid, incurred, or accrued. The preceding
sentence does not apply to the extent that the same
dividends caused a reduction to the addition
modification required under Section 203(a)(2)(D-17) of
this Act. As used in this subparagraph, the term
"intangible expenses and costs" includes (1) expenses,
losses, and costs for, or related to, the direct or
indirect acquisition, use, maintenance or management,
ownership, sale, exchange, or any other disposition of
intangible property; (2) losses incurred, directly or
indirectly, from factoring transactions or discounting
transactions; (3) royalty, patent, technical, and
copyright fees; (4) licensing fees; and (5) other
similar expenses and costs. For purposes of this
subparagraph, "intangible property" includes patents,
patent applications, trade names, trademarks, service
marks, copyrights, mask works, trade secrets, and
similar types of intangible assets.
This paragraph shall not apply to the following:
(i) any item of intangible expenses or costs
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary

HB3580 - 9 - LRB103 05339 SPS 50358 b
reporting, to a tax on or measured by net income
with respect to such item; or
(ii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, if the taxpayer can establish, based
on a preponderance of the evidence, both of the
following:
(a) the person during the same taxable
year paid, accrued, or incurred, the
intangible expense or cost to a person that is
not a related member, and
(b) the transaction giving rise to the
intangible expense or cost between the
taxpayer and the person did not have as a
principal purpose the avoidance of Illinois
income tax, and is paid pursuant to a contract
or agreement that reflects arm's-length terms;
or
(iii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person if
the taxpayer establishes by clear and convincing
evidence, that the adjustments are unreasonable;
or if the taxpayer and the Director agree in
writing to the application or use of an
alternative method of apportionment under Section

HB3580 - 10 - LRB103 05339 SPS 50358 b
304(f);
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act
for any tax year beginning after the effective
date of this amendment provided such adjustment is
made pursuant to regulation adopted by the
Department and such regulations provide methods
and standards by which the Department will utilize
its authority under Section 404 of this Act;
(D-19) For taxable years ending on or after
December 31, 2008, an amount equal to the amount of
insurance premium expenses and costs otherwise allowed
as a deduction in computing base income, and that were
paid, accrued, or incurred, directly or indirectly, to
a person who would be a member of the same unitary
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304. The
addition modification required by this subparagraph
shall be reduced to the extent that dividends were
included in base income of the unitary group for the
same taxable year and received by the taxpayer or by a
member of the taxpayer's unitary business group

HB3580 - 11 - LRB103 05339 SPS 50358 b
(including amounts included in gross income under
Sections 951 through 964 of the Internal Revenue Code
and amounts included in gross income under Section 78
of the Internal Revenue Code) with respect to the
stock of the same person to whom the premiums and costs
were directly or indirectly paid, incurred, or
accrued. The preceding sentence does not apply to the
extent that the same dividends caused a reduction to
the addition modification required under Section
203(a)(2)(D-17) or Section 203(a)(2)(D-18) of this
Act;
(D-20) For taxable years beginning on or after

to the amount excluded from gross income under Section
529(c)(3)(B). For taxable years beginning on or after
January 1, 2007, in the case of a distribution from a
qualified tuition program under Section 529 of the

Section 529 of the Internal Revenue Code that (I)
adopts and determines that its offering materials
comply with the College Savings Plans Network's
disclosure principles and (II) has made reasonable
efforts to inform in-state residents of the existence
of in-state qualified tuition programs by informing
Illinois residents directly and, where applicable, to
inform financial intermediaries distributing the
program to inform in-state residents of the existence
of in-state qualified tuition programs at least
annually, an amount equal to the amount excluded from
gross income under Section 529(c)(3)(B).
For the purposes of this subparagraph (D-20), a
qualified tuition program has made reasonable efforts
if it makes disclosures (which may use the term
"in-state program" or "in-state plan" and need not
specifically refer to Illinois or its qualified
programs by name) (i) directly to prospective
participants in its offering materials or makes a
public disclosure, such as a website posting; and (ii)
where applicable, to intermediaries selling the
out-of-state program in the same manner that the

group but for the fact that the person is prohibited
under Section 1501(a)(27) from being included in the
unitary business group because he or she is ordinarily
required to apportion business income under different
subsections of Section 304. The addition modification
required by this subparagraph shall be reduced to the
extent that dividends were included in base income of
the unitary group for the same taxable year and
received by the taxpayer or by a member of the
taxpayer's unitary business group (including amounts
included in gross income pursuant to Sections 951
through 964 of the Internal Revenue Code and amounts
included in gross income under Section 78 of the
Internal Revenue Code) with respect to the stock of
the same person to whom the interest was paid,

This paragraph shall not apply to the following:
(i) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary
reporting, to a tax on or measured by net income
with respect to such interest; or
(ii) an item of interest paid, accrued, or

HB3580 - 36 - LRB103 05339 SPS 50358 b
incurred, directly or indirectly, to a person if
the taxpayer can establish, based on a
preponderance of the evidence, both of the
following:
(a) the person, during the same taxable
year, paid, accrued, or incurred, the interest
to a person that is not a related member, and
(b) the transaction giving rise to the
interest expense between the taxpayer and the
person did not have as a principal purpose the
avoidance of Illinois income tax, and is paid
pursuant to a contract or agreement that
reflects an arm's-length interest rate and
terms; or
(iii) the taxpayer can establish, based on
clear and convincing evidence, that the interest
paid, accrued, or incurred relates to a contract
or agreement entered into at arm's-length rates
and terms and the principal purpose for the
payment is not federal or Illinois tax avoidance;
or
(iv) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person if
the taxpayer establishes by clear and convincing
evidence that the adjustments are unreasonable; or
if the taxpayer and the Director agree in writing

HB3580 - 37 - LRB103 05339 SPS 50358 b
to the application or use of an alternative method
of apportionment under Section 304(f).
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act

and standards by which the Department will utilize
its authority under Section 404 of this Act;
(E-13) An amount equal to the amount of intangible
expenses and costs otherwise allowed as a deduction in
computing base income, and that were paid, accrued, or
incurred, directly or indirectly, (i) for taxable
years ending on or after December 31, 2004, to a
foreign person who would be a member of the same
unitary business group but for the fact that the
foreign person's business activity outside the United
States is 80% or more of that person's total business
activity and (ii) for taxable years ending on or after
December 31, 2008, to a person who would be a member of
the same unitary business group but for the fact that
the person is prohibited under Section 1501(a)(27)
from being included in the unitary business group
because he or she is ordinarily required to apportion

HB3580 - 38 - LRB103 05339 SPS 50358 b
business income under different subsections of Section
304. The addition modification required by this
subparagraph shall be reduced to the extent that
dividends were included in base income of the unitary
group for the same taxable year and received by the
taxpayer or by a member of the taxpayer's unitary
business group (including amounts included in gross
income pursuant to Sections 951 through 964 of the
Internal Revenue Code and amounts included in gross
income under Section 78 of the Internal Revenue Code)
with respect to the stock of the same person to whom
the intangible expenses and costs were directly or
indirectly paid, incurred, or accrued. The preceding
sentence shall not apply to the extent that the same
dividends caused a reduction to the addition
modification required under Section 203(b)(2)(E-12) of
this Act. As used in this subparagraph, the term
"intangible expenses and costs" includes (1) expenses,
losses, and costs for, or related to, the direct or
indirect acquisition, use, maintenance or management,

subparagraph, "intangible property" includes patents,
patent applications, trade names, trademarks, service
marks, copyrights, mask works, trade secrets, and
similar types of intangible assets.
This paragraph shall not apply to the following:
(i) any item of intangible expenses or costs
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary
reporting, to a tax on or measured by net income
with respect to such item; or
(ii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, if the taxpayer can establish, based
on a preponderance of the evidence, both of the
following:
(a) the person during the same taxable
year paid, accrued, or incurred, the
intangible expense or cost to a person that is
not a related member, and
(b) the transaction giving rise to the
intangible expense or cost between the
taxpayer and the person did not have as a
principal purpose the avoidance of Illinois
income tax, and is paid pursuant to a contract

HB3580 - 40 - LRB103 05339 SPS 50358 b
or agreement that reflects arm's-length terms;
or
(iii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person if
the taxpayer establishes by clear and convincing
evidence, that the adjustments are unreasonable;
or if the taxpayer and the Director agree in
writing to the application or use of an
alternative method of apportionment under Section
304(f);
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act
for any tax year beginning after the effective
date of this amendment provided such adjustment is
made pursuant to regulation adopted by the
Department and such regulations provide methods
and standards by which the Department will utilize
its authority under Section 404 of this Act;
(E-14) For taxable years ending on or after
December 31, 2008, an amount equal to the amount of
insurance premium expenses and costs otherwise allowed
as a deduction in computing base income, and that were
paid, accrued, or incurred, directly or indirectly, to
a person who would be a member of the same unitary

HB3580 - 41 - LRB103 05339 SPS 50358 b
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304. The
addition modification required by this subparagraph
shall be reduced to the extent that dividends were
included in base income of the unitary group for the
same taxable year and received by the taxpayer or by a
member of the taxpayer's unitary business group
(including amounts included in gross income under
Sections 951 through 964 of the Internal Revenue Code
and amounts included in gross income under Section 78
of the Internal Revenue Code) with respect to the
stock of the same person to whom the premiums and costs
were directly or indirectly paid, incurred, or
accrued. The preceding sentence does not apply to the
extent that the same dividends caused a reduction to
the addition modification required under Section
203(b)(2)(E-12) or Section 203(b)(2)(E-13) of this
Act;
(E-15) For taxable years beginning after December

modification required under Section 203(c)(2)(G-12) of
this Act. As used in this subparagraph, the term

following:
(a) the person during the same taxable
year paid, accrued, or incurred, the
intangible expense or cost to a person that is
not a related member, and
(b) the transaction giving rise to the

the taxpayer establishes by clear and convincing
evidence, that the adjustments are unreasonable;
or if the taxpayer and the Director agree in
writing to the application or use of an
alternative method of apportionment under Section
304(f);
Nothing in this subsection shall preclude the
Director from making any other adjustment

paid, accrued, or incurred, directly or indirectly, to

HB3580 - 67 - LRB103 05339 SPS 50358 b
a person who would be a member of the same unitary
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304. The
addition modification required by this subparagraph
shall be reduced to the extent that dividends were
included in base income of the unitary group for the
same taxable year and received by the taxpayer or by a
member of the taxpayer's unitary business group
(including amounts included in gross income under
Sections 951 through 964 of the Internal Revenue Code
and amounts included in gross income under Section 78
of the Internal Revenue Code) with respect to the
stock of the same person to whom the premiums and costs
were directly or indirectly paid, incurred, or

member of the same unitary business group but for the
fact the foreign person's business activity outside
the United States is 80% or more of the foreign
person's total business activity and (ii) for taxable

required to apportion business income under different
subsections of Section 304. The addition modification
required by this subparagraph shall be reduced to the

incurred, directly or indirectly, to a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary
reporting, to a tax on or measured by net income
with respect to such interest; or

year, paid, accrued, or incurred, the interest
to a person that is not a related member, and
(b) the transaction giving rise to the
interest expense between the taxpayer and the
person did not have as a principal purpose the
avoidance of Illinois income tax, and is paid
pursuant to a contract or agreement that
reflects an arm's-length interest rate and
terms; or
(iii) the taxpayer can establish, based on
clear and convincing evidence, that the interest
paid, accrued, or incurred relates to a contract
or agreement entered into at arm's-length rates
and terms and the principal purpose for the
payment is not federal or Illinois tax avoidance;
or
(iv) an item of interest paid, accrued, or
incurred, directly or indirectly, to a person if
the taxpayer establishes by clear and convincing
evidence that the adjustments are unreasonable; or
if the taxpayer and the Director agree in writing
to the application or use of an alternative method
of apportionment under Section 304(f).
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act

HB3580 - 83 - LRB103 05339 SPS 50358 b

foreign person who would be a member of the same
unitary business group but for the fact that the
foreign person's business activity outside the United
States is 80% or more of that person's total business
activity and (ii) for taxable years ending on or after
December 31, 2008, to a person who would be a member of
the same unitary business group but for the fact that
the person is prohibited under Section 1501(a)(27)
from being included in the unitary business group
because he or she is ordinarily required to apportion
business income under different subsections of Section
304. The addition modification required by this
subparagraph shall be reduced to the extent that
dividends were included in base income of the unitary
group for the same taxable year and received by the

HB3580 - 84 - LRB103 05339 SPS 50358 b
taxpayer or by a member of the taxpayer's unitary
business group (including amounts included in gross
income pursuant to Sections 951 through 964 of the
Internal Revenue Code and amounts included in gross
income under Section 78 of the Internal Revenue Code)
with respect to the stock of the same person to whom
the intangible expenses and costs were directly or
indirectly paid, incurred or accrued. The preceding
sentence shall not apply to the extent that the same
dividends caused a reduction to the addition
modification required under Section 203(d)(2)(D-7) of
this Act. As used in this subparagraph, the term
"intangible expenses and costs" includes (1) expenses,
losses, and costs for, or related to, the direct or
indirect acquisition, use, maintenance or management,
ownership, sale, exchange, or any other disposition of
intangible property; (2) losses incurred, directly or

marks, copyrights, mask works, trade secrets, and
similar types of intangible assets;
This paragraph shall not apply to the following:

HB3580 - 85 - LRB103 05339 SPS 50358 b
(i) any item of intangible expenses or costs
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person who
is subject in a foreign country or state, other
than a state which requires mandatory unitary
reporting, to a tax on or measured by net income
with respect to such item; or
(ii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, if the taxpayer can establish, based
on a preponderance of the evidence, both of the
following:
(a) the person during the same taxable
year paid, accrued, or incurred, the
intangible expense or cost to a person that is
not a related member, and
(b) the transaction giving rise to the
intangible expense or cost between the
taxpayer and the person did not have as a
principal purpose the avoidance of Illinois
income tax, and is paid pursuant to a contract
or agreement that reflects arm's-length terms;
or
(iii) any item of intangible expense or cost
paid, accrued, or incurred, directly or
indirectly, from a transaction with a person if

HB3580 - 86 - LRB103 05339 SPS 50358 b
the taxpayer establishes by clear and convincing
evidence, that the adjustments are unreasonable;
or if the taxpayer and the Director agree in
writing to the application or use of an
alternative method of apportionment under Section
304(f);
Nothing in this subsection shall preclude the
Director from making any other adjustment
otherwise allowed under Section 404 of this Act
for any tax year beginning after the effective
date of this amendment provided such adjustment is
made pursuant to regulation adopted by the
Department and such regulations provide methods
and standards by which the Department will utilize
its authority under Section 404 of this Act;
(D-9) For taxable years ending on or after
December 31, 2008, an amount equal to the amount of
insurance premium expenses and costs otherwise allowed
as a deduction in computing base income, and that were
paid, accrued, or incurred, directly or indirectly, to
a person who would be a member of the same unitary
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304. The

HB3580 - 87 - LRB103 05339 SPS 50358 b
addition modification required by this subparagraph
shall be reduced to the extent that dividends were
included in base income of the unitary group for the
same taxable year and received by the taxpayer or by a
member of the taxpayer's unitary business group
(including amounts included in gross income under
Sections 951 through 964 of the Internal Revenue Code
and amounts included in gross income under Section 78
of the Internal Revenue Code) with respect to the
stock of the same person to whom the premiums and costs
were directly or indirectly paid, incurred, or

the addition modification required under Section
203(d)(2)(D-7) or Section 203(d)(2)(D-8) of this Act;

the taxpayer under Section 218(a) of this Act,

(3) for taxable years ending after December
31, 2005:
(i) for property on which a bonus
depreciation deduction of 30% of the adjusted
basis was taken, "x" equals "y" multiplied by
30 and then divided by 70 (or "y" multiplied
by 0.429);
(ii) for property on which a bonus
depreciation deduction of 50% of the adjusted
basis was taken, "x" equals "y" multiplied by
1.0;
(iii) for property on which a bonus
depreciation deduction of 100% of the adjusted
basis was taken in a taxable year ending on or
after December 31, 2021, "x" equals the
depreciation deduction that would be allowed

HB3580 - 92 - LRB103 05339 SPS 50358 b
on that property if the taxpayer had made the
election under Section 168(k)(7) of the
Internal Revenue Code to not claim bonus
depreciation on that property; and
(iv) for property on which a bonus
depreciation deduction of a percentage other
than 30%, 50% or 100% of the adjusted basis
was taken in a taxable year ending on or after
December 31, 2021, "x" equals "y" multiplied
by 100 times the percentage bonus depreciation
on the property (that is, 100(bonus%)) and
then divided by 100 times 1 minus the
percentage bonus depreciation on the property
(that is, 100(1–bonus%)).
The aggregate amount deducted under this
subparagraph in all taxable years for any one piece of
property may not exceed the amount of the bonus
depreciation deduction taken on that property on the
taxpayer's federal income tax return under subsection
(k) of Section 168 of the Internal Revenue Code. This
subparagraph (O) is exempt from the provisions of
Section 250;
(P) If the taxpayer sells, transfers, abandons, or
otherwise disposes of property for which the taxpayer
was required in any taxable year to make an addition
modification under subparagraph (D-5), then an amount

HB3580 - 93 - LRB103 05339 SPS 50358 b
equal to that addition modification.
If the taxpayer continues to own property through
the last day of the last tax year for which a taxpayer
may claim a depreciation deduction for federal income
tax purposes a subtraction is allowed with respect to
that property under subparagraph (O) and for which the
taxpayer was required in any taxable year to make an
addition modification under subparagraph (D-5), then
an amount equal to that addition modification.
The taxpayer is allowed to take the deduction
under this subparagraph only once with respect to any
one piece of property.
This subparagraph (P) is exempt from the
provisions of Section 250;
(Q) The amount of (i) any interest income (net of
the deductions allocable thereto) taken into account
for the taxable year with respect to a transaction
with a taxpayer that is required to make an addition
modification with respect to such transaction under
Section 203(a)(2)(D-17), 203(b)(2)(E-12),
203(c)(2)(G-12), or 203(d)(2)(D-7), but not to exceed
the amount of such addition modification and (ii) any
income from intangible property (net of the deductions
allocable thereto) taken into account for the taxable
year with respect to a transaction with a taxpayer
that is required to make an addition modification with

HB3580 - 94 - LRB103 05339 SPS 50358 b
respect to such transaction under Section
203(a)(2)(D-18), 203(b)(2)(E-13), 203(c)(2)(G-13), or
203(d)(2)(D-8), but not to exceed the amount of such
addition modification. This subparagraph (Q) is exempt
from Section 250;
(R) An amount equal to the interest income taken
into account for the taxable year (net of the
deductions allocable thereto) with respect to
transactions with (i) a foreign person who would be a
member of the taxpayer's unitary business group but
for the fact that the foreign person's business
activity outside the United States is 80% or more of
that person's total business activity and (ii) for
taxable years ending on or after December 31, 2008, to
a person who would be a member of the same unitary
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304, but
not to exceed the addition modification required to be
made for the same taxable year under Section
203(d)(2)(D-7) for interest paid, accrued, or
incurred, directly or indirectly, to the same person.
This subparagraph (R) is exempt from Section 250;
(S) An amount equal to the income from intangible

HB3580 - 95 - LRB103 05339 SPS 50358 b
property taken into account for the taxable year (net
of the deductions allocable thereto) with respect to
transactions with (i) a foreign person who would be a
member of the taxpayer's unitary business group but
for the fact that the foreign person's business
activity outside the United States is 80% or more of
that person's total business activity and (ii) for
taxable years ending on or after December 31, 2008, to
a person who would be a member of the same unitary
business group but for the fact that the person is
prohibited under Section 1501(a)(27) from being
included in the unitary business group because he or
she is ordinarily required to apportion business
income under different subsections of Section 304, but
not to exceed the addition modification required to be
made for the same taxable year under Section
203(d)(2)(D-8) for intangible expenses and costs paid,
accrued, or incurred, directly or indirectly, to the
same person. This subparagraph (S) is exempt from
Section 250; and
(T) For taxable years ending on or after December
31, 2011, in the case of a taxpayer who was required to
add back any insurance premiums under Section
203(d)(2)(D-9), such taxpayer may elect to subtract
that part of a reimbursement received from the
insurance company equal to the amount of the expense

HB3580 - 96 - LRB103 05339 SPS 50358 b
or loss (including expenses incurred by the insurance
company) that would have been taken into account as a
deduction for federal income tax purposes if the
expense or loss had been uninsured. If a taxpayer
makes the election provided for by this subparagraph
(T), the insurer to which the premiums were paid must
add back to income the amount subtracted by the
taxpayer pursuant to this subparagraph (T). This
subparagraph (T) is exempt from the provisions of
Section 250.
(e) Gross income; adjusted gross income; taxable income.
(1) In general. Subject to the provisions of paragraph
(2) and subsection (b)(3), for purposes of this Section
and Section 803(e), a taxpayer's gross income, adjusted
gross income, or taxable income for the taxable year shall
mean the amount of gross income, adjusted gross income or
taxable income properly reportable for federal income tax
purposes for the taxable year under the provisions of the
Internal Revenue Code. Taxable income may be less than
zero. However, for taxable years ending on or after
December 31, 1986, net operating loss carryforwards from
taxable years ending prior to December 31, 1986, may not
exceed the sum of federal taxable income for the taxable
year before net operating loss deduction, plus the excess
of addition modifications over subtraction modifications

HB3580 - 97 - LRB103 05339 SPS 50358 b
for the taxable year. For taxable years ending prior to
December 31, 1986, taxable income may never be an amount
in excess of the net operating loss for the taxable year as
defined in subsections (c) and (d) of Section 172 of the
Internal Revenue Code, provided that when taxable income
of a corporation (other than a Subchapter S corporation),
trust, or estate is less than zero and addition
modifications, other than those provided by subparagraph
(E) of paragraph (2) of subsection (b) for corporations or
subparagraph (E) of paragraph (2) of subsection (c) for
trusts and estates, exceed subtraction modifications, an
addition modification must be made under those
subparagraphs for any other taxable year to which the
taxable income less than zero (net operating loss) is
applied under Section 172 of the Internal Revenue Code or
under subparagraph (E) of paragraph (2) of this subsection
(e) applied in conjunction with Section 172 of the
Internal Revenue Code.
(2) Special rule. For purposes of paragraph (1) of
this subsection, the taxable income properly reportable
for federal income tax purposes shall mean:
(A) Certain life insurance companies. In the case
of a life insurance company subject to the tax imposed
by Section 801 of the Internal Revenue Code, life
insurance company taxable income, plus the amount of
distribution from pre-1984 policyholder surplus

HB3580 - 98 - LRB103 05339 SPS 50358 b
accounts as calculated under Section 815a of the
Internal Revenue Code;
(B) Certain other insurance companies. In the case
of mutual insurance companies subject to the tax
imposed by Section 831 of the Internal Revenue Code,
insurance company taxable income;
(C) Regulated investment companies. In the case of
a regulated investment company subject to the tax
imposed by Section 852 of the Internal Revenue Code,
investment company taxable income;
(D) Real estate investment trusts. In the case of
a real estate investment trust subject to the tax
imposed by Section 857 of the Internal Revenue Code,
real estate investment trust taxable income;
(E) Consolidated corporations. In the case of a
corporation which is a member of an affiliated group
of corporations filing a consolidated income tax
return for the taxable year for federal income tax
purposes, taxable income determined as if such
corporation had filed a separate return for federal
income tax purposes for the taxable year and each
preceding taxable year for which it was a member of an
affiliated group. For purposes of this subparagraph,
the taxpayer's separate taxable income shall be
determined as if the election provided by Section
243(b)(2) of the Internal Revenue Code had been in

HB3580 - 99 - LRB103 05339 SPS 50358 b
effect for all such years;
(F) Cooperatives. In the case of a cooperative
corporation or association, the taxable income of such
organization determined in accordance with the
provisions of Section 1381 through 1388 of the
Internal Revenue Code, but without regard to the
prohibition against offsetting losses from patronage
activities against income from nonpatronage
activities; except that a cooperative corporation or
association may make an election to follow its federal
income tax treatment of patronage losses and
nonpatronage losses. In the event such election is
made, such losses shall be computed and carried over
in a manner consistent with subsection (a) of Section
207 of this Act and apportioned by the apportionment
factor reported by the cooperative on its Illinois
income tax return filed for the taxable year in which
the losses are incurred. The election shall be
effective for all taxable years with original returns
due on or after the date of the election. In addition,
the cooperative may file an amended return or returns,
as allowed under this Act, to provide that the
election shall be effective for losses incurred or
carried forward for taxable years occurring prior to
the date of the election. Once made, the election may
only be revoked upon approval of the Director. The

HB3580 - 100 - LRB103 05339 SPS 50358 b
Department shall adopt rules setting forth
requirements for documenting the elections and any
resulting Illinois net loss and the standards to be
used by the Director in evaluating requests to revoke
elections. Public Act 96-932 is declaratory of
existing law;
(G) Subchapter S corporations. In the case of: (i)
a Subchapter S corporation for which there is in
effect an election for the taxable year under Section
1362 of the Internal Revenue Code, the taxable income
of such corporation determined in accordance with
Section 1363(b) of the Internal Revenue Code, except
that taxable income shall take into account those
items which are required by Section 1363(b)(1) of the
Internal Revenue Code to be separately stated; and
(ii) a Subchapter S corporation for which there is in
effect a federal election to opt out of the provisions
of the Subchapter S Revision Act of 1982 and have
applied instead the prior federal Subchapter S rules
as in effect on July 1, 1982, the taxable income of
such corporation determined in accordance with the
federal Subchapter S rules as in effect on July 1,
1982; and
(H) Partnerships. In the case of a partnership,
taxable income determined in accordance with Section
703 of the Internal Revenue Code, except that taxable

HB3580 - 101 - LRB103 05339 SPS 50358 b
income shall take into account those items which are
required by Section 703(a)(1) to be separately stated
but which would be taken into account by an individual
in calculating his taxable income.
(3) Recapture of business expenses on disposition of
asset or business. Notwithstanding any other law to the
contrary, if in prior years income from an asset or
business has been classified as business income and in a
later year is demonstrated to be non-business income, then
all expenses, without limitation, deducted in such later
year and in the 2 immediately preceding taxable years
related to that asset or business that generated the
non-business income shall be added back and recaptured as
business income in the year of the disposition of the
asset or business. Such amount shall be apportioned to
Illinois using the greater of the apportionment fraction
computed for the business under Section 304 of this Act
for the taxable year or the average of the apportionment
fractions computed for the business under Section 304 of
this Act for the taxable year and for the 2 immediately
preceding taxable years.
(f) Valuation limitation amount.
(1) In general. The valuation limitation amount
referred to in subsections (a)(2)(G), (c)(2)(I) and
(d)(2)(E) is an amount equal to:

HB3580 - 102 - LRB103 05339 SPS 50358 b
(A) The sum of the pre-August 1, 1969 appreciation
amounts (to the extent consisting of gain reportable
under the provisions of Section 1245 or 1250 of the
Internal Revenue Code) for all property in respect of
which such gain was reported for the taxable year;
plus
(B) The lesser of (i) the sum of the pre-August 1,
1969 appreciation amounts (to the extent consisting of
capital gain) for all property in respect of which
such gain was reported for federal income tax purposes
for the taxable year, or (ii) the net capital gain for
the taxable year, reduced in either case by any amount
of such gain included in the amount determined under
subsection (a)(2)(F) or (c)(2)(H).
(2) Pre-August 1, 1969 appreciation amount.
(A) If the fair market value of property referred
to in paragraph (1) was readily ascertainable on
August 1, 1969, the pre-August 1, 1969 appreciation
amount for such property is the lesser of (i) the
excess of such fair market value over the taxpayer's
basis (for determining gain) for such property on that
date (determined under the Internal Revenue Code as in
effect on that date), or (ii) the total gain realized
and reportable for federal income tax purposes in
respect of the sale, exchange or other disposition of
such property.

HB3580 - 103 - LRB103 05339 SPS 50358 b
(B) If the fair market value of property referred
to in paragraph (1) was not readily ascertainable on
August 1, 1969, the pre-August 1, 1969 appreciation
amount for such property is that amount which bears
the same ratio to the total gain reported in respect of
the property for federal income tax purposes for the
taxable year, as the number of full calendar months in
that part of the taxpayer's holding period for the
property ending July 31, 1969 bears to the number of
full calendar months in the taxpayer's entire holding
period for the property.
(C) The Department shall prescribe such
regulations as may be necessary to carry out the
purposes of this paragraph.
(g) Double deductions. Unless specifically provided
otherwise, nothing in this Section shall permit the same item
to be deducted more than once.
(h) Legislative intention. Except as expressly provided by
this Section there shall be no modifications or limitations on
the amounts of income, gain, loss or deduction taken into
account in determining gross income, adjusted gross income or
taxable income for federal income tax purposes for the taxable
year, or in the amount of such items entering into the
computation of base income and net income under this Act for

HB3580 - 104 - LRB103 05339 SPS 50358 b
such taxable year, whether in respect of property values as of
August 1, 1969 or otherwise.
