9 member of the same unitary business group but for the
10 fact that foreign person's business activity outside
11 the United States is 80% or more of the foreign
12 person's total business activity and (ii) for taxable
13 years ending on or after December 31, 2008, to a person
14 who would be a member of the same unitary business
15 group but for the fact that the person is prohibited
16 under Section 1501(a)(27) from being included in the
17 unitary business group because he or she is ordinarily
18 required to apportion business income under different
19 subsections of Section 304. The addition modification
20 required by this subparagraph shall be reduced to the
21 extent that dividends were included in base income of
22 the unitary group for the same taxable year and
23 received by the taxpayer or by a member of the
24 taxpayer's unitary business group (including amounts
25 included in gross income under Sections 951 through
26 964 of the Internal Revenue Code and amounts included

HB3310- 5 -LRB104 10872 HLH 20954 b
1 in gross income under Section 78 of the Internal
2 Revenue Code) with respect to the stock of the same
3 person to whom the interest was paid, accrued, or
4 incurred.
5            This paragraph shall not apply to the following:
6                (i) an item of interest paid, accrued, or
7 incurred, directly or indirectly, to a person who
8 is subject in a foreign country or state, other
9 than a state which requires mandatory unitary
10 reporting, to a tax on or measured by net income
11 with respect to such interest; or
12                (ii) an item of interest paid, accrued, or
13 incurred, directly or indirectly, to a person if
14 the taxpayer can establish, based on a
15 preponderance of the evidence, both of the
16 following:
17                    (a) the person, during the same taxable
18 year, paid, accrued, or incurred, the interest
19 to a person that is not a related member, and
20                    (b) the transaction giving rise to the
21 interest expense between the taxpayer and the
22 person did not have as a principal purpose the
23 avoidance of Illinois income tax, and is paid
24 pursuant to a contract or agreement that
25 reflects an arm's-length interest rate and
26 terms; or

HB3310- 6 -LRB104 10872 HLH 20954 b
1                (iii) the taxpayer can establish, based on
2 clear and convincing evidence, that the interest
3 paid, accrued, or incurred relates to a contract
4 or agreement entered into at arm's-length rates
5 and terms and the principal purpose for the
6 payment is not federal or Illinois tax avoidance;
7 or
8                (iv) an item of interest paid, accrued, or
9 incurred, directly or indirectly, to a person if
10 the taxpayer establishes by clear and convincing
11 evidence that the adjustments are unreasonable; or
12 if the taxpayer and the Director agree in writing
13 to the application or use of an alternative method
14 of apportionment under Section 304(f).
15                Nothing in this subsection shall preclude the
16 Director from making any other adjustment
17 otherwise allowed under Section 404 of this Act
18 for any tax year beginning after the effective
19 date of this amendment provided such adjustment is
20 made pursuant to regulation adopted by the
21 Department and such regulations provide methods
22 and standards by which the Department will utilize
23 its authority under Section 404 of this Act;
24            (D-18) An amount equal to the amount of intangible
25 expenses and costs otherwise allowed as a deduction in
26 computing base income, and that were paid, accrued, or

HB3310- 7 -LRB104 10872 HLH 20954 b
1 incurred, directly or indirectly, (i) for taxable
2 years ending on or after December 31, 2004, to a
3 foreign person who would be a member of the same
4 unitary business group but for the fact that the
5 foreign person's business activity outside the United
6 States is 80% or more of that person's total business
7 activity and (ii) for taxable years ending on or after
8 December 31, 2008, to a person who would be a member of
9 the same unitary business group but for the fact that
10 the person is prohibited under Section 1501(a)(27)
11 from being included in the unitary business group
12 because he or she is ordinarily required to apportion
13 business income under different subsections of Section
14 304. The addition modification required by this
15 subparagraph shall be reduced to the extent that
16 dividends were included in base income of the unitary
17 group for the same taxable year and received by the
18 taxpayer or by a member of the taxpayer's unitary
19 business group (including amounts included in gross
20 income under Sections 951 through 964 of the Internal
21 Revenue Code and amounts included in gross income
22 under Section 78 of the Internal Revenue Code) with
23 respect to the stock of the same person to whom the
24 intangible expenses and costs were directly or
25 indirectly paid, incurred, or accrued. The preceding
26 sentence does not apply to the extent that the same

HB3310- 8 -LRB104 10872 HLH 20954 b
1 dividends caused a reduction to the addition
2 modification required under Section 203(a)(2)(D-17) of
3 this Act. As used in this subparagraph, the term
4 "intangible expenses and costs" includes (1) expenses,
5 losses, and costs for, or related to, the direct or
6 indirect acquisition, use, maintenance or management,
7 ownership, sale, exchange, or any other disposition of
8 intangible property; (2) losses incurred, directly or
9 indirectly, from factoring transactions or discounting
10 transactions; (3) royalty, patent, technical, and
11 copyright fees; (4) licensing fees; and (5) other
12 similar expenses and costs. For purposes of this
13 subparagraph, "intangible property" includes patents,
14 patent applications, trade names, trademarks, service
15 marks, copyrights, mask works, trade secrets, and
16 similar types of intangible assets.
17            This paragraph shall not apply to the following:
18                (i) any item of intangible expenses or costs
19 paid, accrued, or incurred, directly or
20 indirectly, from a transaction with a person who
21 is subject in a foreign country or state, other
22 than a state which requires mandatory unitary
23 reporting, to a tax on or measured by net income
24 with respect to such item; or
25                (ii) any item of intangible expense or cost
26 paid, accrued, or incurred, directly or

HB3310- 9 -LRB104 10872 HLH 20954 b
1 indirectly, if the taxpayer can establish, based
2 on a preponderance of the evidence, both of the
3 following:
4                    (a) the person during the same taxable
5 year paid, accrued, or incurred, the
6 intangible expense or cost to a person that is
7 not a related member, and
8                    (b) the transaction giving rise to the
9 intangible expense or cost between the
10 taxpayer and the person did not have as a
11 principal purpose the avoidance of Illinois
12 income tax, and is paid pursuant to a contract
13 or agreement that reflects arm's-length terms;
14 or
15                (iii) any item of intangible expense or cost
16 paid, accrued, or incurred, directly or
17 indirectly, from a transaction with a person if
18 the taxpayer establishes by clear and convincing
19 evidence, that the adjustments are unreasonable;
20 or if the taxpayer and the Director agree in
21 writing to the application or use of an
22 alternative method of apportionment under Section
23 304(f);
24                Nothing in this subsection shall preclude the
25 Director from making any other adjustment
26 otherwise allowed under Section 404 of this Act

HB3310- 10 -LRB104 10872 HLH 20954 b
1 for any tax year beginning after the effective
2 date of this amendment provided such adjustment is
3 made pursuant to regulation adopted by the
4 Department and such regulations provide methods
5 and standards by which the Department will utilize
6 its authority under Section 404 of this Act;
7            (D-19) For taxable years ending on or after
8 December 31, 2008, an amount equal to the amount of
9 insurance premium expenses and costs otherwise allowed
10 as a deduction in computing base income, and that were
11 paid, accrued, or incurred, directly or indirectly, to
12 a person who would be a member of the same unitary
13 business group but for the fact that the person is
14 prohibited under Section 1501(a)(27) from being
15 included in the unitary business group because he or
16 she is ordinarily required to apportion business
17 income under different subsections of Section 304. The
18 addition modification required by this subparagraph
19 shall be reduced to the extent that dividends were
20 included in base income of the unitary group for the
21 same taxable year and received by the taxpayer or by a
22 member of the taxpayer's unitary business group
23 (including amounts included in gross income under
24 Sections 951 through 964 of the Internal Revenue Code
25 and amounts included in gross income under Section 78
26 of the Internal Revenue Code) with respect to the

HB3310- 11 -LRB104 10872 HLH 20954 b
1 stock of the same person to whom the premiums and costs
2 were directly or indirectly paid, incurred, or
3 accrued. The preceding sentence does not apply to the
4 extent that the same dividends caused a reduction to
5 the addition modification required under Section
6 203(a)(2)(D-17) or Section 203(a)(2)(D-18) of this
7 Act;
8            (D-20) For taxable years beginning on or after

12 Revenue Code, other than (i) a distribution from a
13 College Savings Pool created under Section 16.5 of the
14 State Treasurer Act or (ii) a distribution from the
15 Illinois Prepaid Tuition Trust Fund, an amount equal
16 to the amount excluded from gross income under Section
17 529(c)(3)(B). For taxable years beginning on or after
18 January 1, 2007, in the case of a distribution from a
19 qualified tuition program under Section 529 of the
20 Internal Revenue Code, other than (i) a distribution

22 of the State Treasurer Act, (ii) a distribution from
23 the Illinois Prepaid Tuition Trust Fund, or (iii) a

26 adopts and determines that its offering materials

17 participants in its offering materials or makes a
18 public disclosure, such as a website posting; and (ii)

19 preponderance of the evidence, both of the
20 following:
21                    (a) the person, during the same taxable
22 year, paid, accrued, or incurred, the interest
23 to a person that is not a related member, and
24                    (b) the transaction giving rise to the
25 interest expense between the taxpayer and the
26 person did not have as a principal purpose the

HB3310- 38 -LRB104 10872 HLH 20954 b
1 avoidance of Illinois income tax, and is paid
2 pursuant to a contract or agreement that
3 reflects an arm's-length interest rate and
4 terms; or
5                (iii) the taxpayer can establish, based on
6 clear and convincing evidence, that the interest
7 paid, accrued, or incurred relates to a contract
8 or agreement entered into at arm's-length rates
9 and terms and the principal purpose for the
10 payment is not federal or Illinois tax avoidance;
11 or
12                (iv) an item of interest paid, accrued, or
13 incurred, directly or indirectly, to a person if
14 the taxpayer establishes by clear and convincing
15 evidence that the adjustments are unreasonable; or
16 if the taxpayer and the Director agree in writing
17 to the application or use of an alternative method
18 of apportionment under Section 304(f).
19                Nothing in this subsection shall preclude the
20 Director from making any other adjustment
21 otherwise allowed under Section 404 of this Act
22 for any tax year beginning after the effective
23 date of this amendment provided such adjustment is
24 made pursuant to regulation adopted by the
25 Department and such regulations provide methods
26 and standards by which the Department will utilize

HB3310- 39 -LRB104 10872 HLH 20954 b
1 its authority under Section 404 of this Act;
2            (E-13) An amount equal to the amount of intangible
3 expenses and costs otherwise allowed as a deduction in
4 computing base income, and that were paid, accrued, or
5 incurred, directly or indirectly, (i) for taxable
6 years ending on or after December 31, 2004, to a
7 foreign person who would be a member of the same
8 unitary business group but for the fact that the
9 foreign person's business activity outside the United
10 States is 80% or more of that person's total business
11 activity and (ii) for taxable years ending on or after
12 December 31, 2008, to a person who would be a member of
13 the same unitary business group but for the fact that
14 the person is prohibited under Section 1501(a)(27)
15 from being included in the unitary business group
16 because he or she is ordinarily required to apportion
17 business income under different subsections of Section
18 304. The addition modification required by this
19 subparagraph shall be reduced to the extent that
20 dividends were included in base income of the unitary
21 group for the same taxable year and received by the

1 with respect to the stock of the same person to whom
2 the intangible expenses and costs were directly or
3 indirectly paid, incurred, or accrued. The preceding
4 sentence shall not apply to the extent that the same
5 dividends caused a reduction to the addition
6 modification required under Section 203(b)(2)(E-12) of
7 this Act. As used in this subparagraph, the term
8 "intangible expenses and costs" includes (1) expenses,
9 losses, and costs for, or related to, the direct or
10 indirect acquisition, use, maintenance or management,
11 ownership, sale, exchange, or any other disposition of
12 intangible property; (2) losses incurred, directly or
13 indirectly, from factoring transactions or discounting
14 transactions; (3) royalty, patent, technical, and
15 copyright fees; (4) licensing fees; and (5) other
16 similar expenses and costs. For purposes of this
17 subparagraph, "intangible property" includes patents,
18 patent applications, trade names, trademarks, service
19 marks, copyrights, mask works, trade secrets, and

23 paid, accrued, or incurred, directly or
24 indirectly, from a transaction with a person who
25 is subject in a foreign country or state, other
26 than a state which requires mandatory unitary

1 reporting, to a tax on or measured by net income
2 with respect to such item; or
3                (ii) any item of intangible expense or cost
4 paid, accrued, or incurred, directly or
5 indirectly, if the taxpayer can establish, based
6 on a preponderance of the evidence, both of the
7 following:
8                    (a) the person during the same taxable
9 year paid, accrued, or incurred, the
10 intangible expense or cost to a person that is
11 not a related member, and
12                    (b) the transaction giving rise to the
13 intangible expense or cost between the
14 taxpayer and the person did not have as a
15 principal purpose the avoidance of Illinois
16 income tax, and is paid pursuant to a contract
17 or agreement that reflects arm's-length terms;
18 or
19                (iii) any item of intangible expense or cost
20 paid, accrued, or incurred, directly or
21 indirectly, from a transaction with a person if
22 the taxpayer establishes by clear and convincing
23 evidence, that the adjustments are unreasonable;
24 or if the taxpayer and the Director agree in
25 writing to the application or use of an
26 alternative method of apportionment under Section

HB3310- 42 -LRB104 10872 HLH 20954 b
1 304(f);
2                Nothing in this subsection shall preclude the
3 Director from making any other adjustment
4 otherwise allowed under Section 404 of this Act
5 for any tax year beginning after the effective
6 date of this amendment provided such adjustment is
7 made pursuant to regulation adopted by the
8 Department and such regulations provide methods
9 and standards by which the Department will utilize
10 its authority under Section 404 of this Act;
11            (E-14) For taxable years ending on or after
12 December 31, 2008, an amount equal to the amount of
13 insurance premium expenses and costs otherwise allowed
14 as a deduction in computing base income, and that were
15 paid, accrued, or incurred, directly or indirectly, to
16 a person who would be a member of the same unitary
17 business group but for the fact that the person is
18 prohibited under Section 1501(a)(27) from being
19 included in the unitary business group because he or
20 she is ordinarily required to apportion business
21 income under different subsections of Section 304. The
22 addition modification required by this subparagraph
23 shall be reduced to the extent that dividends were
24 included in base income of the unitary group for the
25 same taxable year and received by the taxpayer or by a
26 member of the taxpayer's unitary business group

HB3310- 43 -LRB104 10872 HLH 20954 b

4 of the Internal Revenue Code) with respect to the
5 stock of the same person to whom the premiums and costs
6 were directly or indirectly paid, incurred, or
7 accrued. The preceding sentence does not apply to the
8 extent that the same dividends caused a reduction to
9 the addition modification required under Section

11 Act;

16 made for the same taxable year under Section
17 203(b)(2)(E-12) for interest paid, accrued, or

12 with respect to such interest; or
13                (ii) an item of interest paid, accrued, or
14 incurred, directly or indirectly, to a person if
15 the taxpayer can establish, based on a
16 preponderance of the evidence, both of the
17 following:
18                    (a) the person, during the same taxable
19 year, paid, accrued, or incurred, the interest
20 to a person that is not a related member, and
21                    (b) the transaction giving rise to the
22 interest expense between the taxpayer and the
23 person did not have as a principal purpose the
24 avoidance of Illinois income tax, and is paid
25 pursuant to a contract or agreement that
26 reflects an arm's-length interest rate and

HB3310- 65 -LRB104 10872 HLH 20954 b
1 terms; or
2                (iii) the taxpayer can establish, based on
3 clear and convincing evidence, that the interest
4 paid, accrued, or incurred relates to a contract

8 or
9                (iv) an item of interest paid, accrued, or

11 the taxpayer establishes by clear and convincing
12 evidence that the adjustments are unreasonable; or

15 of apportionment under Section 304(f).
16                Nothing in this subsection shall preclude the
17 Director from making any other adjustment
18 otherwise allowed under Section 404 of this Act
19 for any tax year beginning after the effective
20 date of this amendment provided such adjustment is
21 made pursuant to regulation adopted by the

23 and standards by which the Department will utilize
24 its authority under Section 404 of this Act;
25            (G-13) An amount equal to the amount of intangible
26 expenses and costs otherwise allowed as a deduction in

HB3310- 66 -LRB104 10872 HLH 20954 b
1 computing base income, and that were paid, accrued, or
2 incurred, directly or indirectly, (i) for taxable
3 years ending on or after December 31, 2004, to a
4 foreign person who would be a member of the same
5 unitary business group but for the fact that the
6 foreign person's business activity outside the United
7 States is 80% or more of that person's total business
8 activity and (ii) for taxable years ending on or after
9 December 31, 2008, to a person who would be a member of
10 the same unitary business group but for the fact that
11 the person is prohibited under Section 1501(a)(27)
12 from being included in the unitary business group
13 because he or she is ordinarily required to apportion
14 business income under different subsections of Section
15 304. The addition modification required by this
16 subparagraph shall be reduced to the extent that
17 dividends were included in base income of the unitary
18 group for the same taxable year and received by the
19 taxpayer or by a member of the taxpayer's unitary
20 business group (including amounts included in gross
21 income pursuant to Sections 951 through 964 of the

23 income under Section 78 of the Internal Revenue Code)
24 with respect to the stock of the same person to whom
25 the intangible expenses and costs were directly or
26 indirectly paid, incurred, or accrued. The preceding

HB3310- 67 -LRB104 10872 HLH 20954 b
1 sentence shall not apply to the extent that the same
2 dividends caused a reduction to the addition
3 modification required under Section 203(c)(2)(G-12) of
4 this Act. As used in this subparagraph, the term
5 "intangible expenses and costs" includes: (1)
6 expenses, losses, and costs for or related to the

20 paid, accrued, or incurred, directly or
21 indirectly, from a transaction with a person who
22 is subject in a foreign country or state, other
23 than a state which requires mandatory unitary
24 reporting, to a tax on or measured by net income
25 with respect to such item; or
26                (ii) any item of intangible expense or cost

HB3310- 68 -LRB104 10872 HLH 20954 b
1 paid, accrued, or incurred, directly or
2 indirectly, if the taxpayer can establish, based
3 on a preponderance of the evidence, both of the
4 following:
5                    (a) the person during the same taxable
6 year paid, accrued, or incurred, the
7 intangible expense or cost to a person that is
8 not a related member, and
9                    (b) the transaction giving rise to the
10 intangible expense or cost between the
11 taxpayer and the person did not have as a
12 principal purpose the avoidance of Illinois
13 income tax, and is paid pursuant to a contract
14 or agreement that reflects arm's-length terms;
15 or
16                (iii) any item of intangible expense or cost
17 paid, accrued, or incurred, directly or
18 indirectly, from a transaction with a person if
19 the taxpayer establishes by clear and convincing
20 evidence, that the adjustments are unreasonable;
21 or if the taxpayer and the Director agree in
22 writing to the application or use of an
23 alternative method of apportionment under Section
24 304(f);
25                Nothing in this subsection shall preclude the
26 Director from making any other adjustment

1 otherwise allowed under Section 404 of this Act
2 for any tax year beginning after the effective
3 date of this amendment provided such adjustment is

7 its authority under Section 404 of this Act;
8            (G-14) For taxable years ending on or after
9 December 31, 2008, an amount equal to the amount of
10 insurance premium expenses and costs otherwise allowed
11 as a deduction in computing base income, and that were
12 paid, accrued, or incurred, directly or indirectly, to
13 a person who would be a member of the same unitary
14 business group but for the fact that the person is
15 prohibited under Section 1501(a)(27) from being
16 included in the unitary business group because he or
17 she is ordinarily required to apportion business
18 income under different subsections of Section 304. The
19 addition modification required by this subparagraph
20 shall be reduced to the extent that dividends were
21 included in base income of the unitary group for the
22 same taxable year and received by the taxpayer or by a
23 member of the taxpayer's unitary business group
24 (including amounts included in gross income under
25 Sections 951 through 964 of the Internal Revenue Code

1 of the Internal Revenue Code) with respect to the
2 stock of the same person to whom the premiums and costs
3 were directly or indirectly paid, incurred, or
4 accrued. The preceding sentence does not apply to the

8 Act;

1 preponderance of the evidence, both of the
2 following:
3                    (a) the person, during the same taxable
4 year, paid, accrued, or incurred, the interest
5 to a person that is not a related member, and
6                    (b) the transaction giving rise to the
7 interest expense between the taxpayer and the
8 person did not have as a principal purpose the
9 avoidance of Illinois income tax, and is paid
10 pursuant to a contract or agreement that
11 reflects an arm's-length interest rate and
12 terms; or
13                (iii) the taxpayer can establish, based on
14 clear and convincing evidence, that the interest
15 paid, accrued, or incurred relates to a contract
16 or agreement entered into at arm's-length rates

19 or

22 the taxpayer establishes by clear and convincing

10            (D-8) An amount equal to the amount of intangible
11 expenses and costs otherwise allowed as a deduction in
12 computing base income, and that were paid, accrued, or
13 incurred, directly or indirectly, (i) for taxable
14 years ending on or after December 31, 2004, to a
15 foreign person who would be a member of the same
16 unitary business group but for the fact that the
17 foreign person's business activity outside the United
18 States is 80% or more of that person's total business
19 activity and (ii) for taxable years ending on or after
20 December 31, 2008, to a person who would be a member of
21 the same unitary business group but for the fact that

23 from being included in the unitary business group
24 because he or she is ordinarily required to apportion
25 business income under different subsections of Section
26 304. The addition modification required by this

HB3310- 87 -LRB104 10872 HLH 20954 b

8 income under Section 78 of the Internal Revenue Code)
9 with respect to the stock of the same person to whom
10 the intangible expenses and costs were directly or

12 sentence shall not apply to the extent that the same
13 dividends caused a reduction to the addition
14 modification required under Section 203(d)(2)(D-7) of
15 this Act. As used in this subparagraph, the term
16 "intangible expenses and costs" includes (1) expenses,

3            This paragraph shall not apply to the following:
4                (i) any item of intangible expenses or costs
5 paid, accrued, or incurred, directly or
6 indirectly, from a transaction with a person who
7 is subject in a foreign country or state, other
8 than a state which requires mandatory unitary
9 reporting, to a tax on or measured by net income
10 with respect to such item; or
11                (ii) any item of intangible expense or cost
12 paid, accrued, or incurred, directly or

15 following:
16                    (a) the person during the same taxable
17 year paid, accrued, or incurred, the
18 intangible expense or cost to a person that is
19 not a related member, and
20                    (b) the transaction giving rise to the
21 intangible expense or cost between the
22 taxpayer and the person did not have as a
23 principal purpose the avoidance of Illinois
24 income tax, and is paid pursuant to a contract
25 or agreement that reflects arm's-length terms;
26 or

HB3310- 89 -LRB104 10872 HLH 20954 b
1                (iii) any item of intangible expense or cost
2 paid, accrued, or incurred, directly or
3 indirectly, from a transaction with a person if
4 the taxpayer establishes by clear and convincing
5 evidence, that the adjustments are unreasonable;
6 or if the taxpayer and the Director agree in
7 writing to the application or use of an
8 alternative method of apportionment under Section
9 304(f);
10                Nothing in this subsection shall preclude the
11 Director from making any other adjustment
12 otherwise allowed under Section 404 of this Act
13 for any tax year beginning after the effective
14 date of this amendment provided such adjustment is
15 made pursuant to regulation adopted by the
16 Department and such regulations provide methods
17 and standards by which the Department will utilize
18 its authority under Section 404 of this Act;
19            (D-9) For taxable years ending on or after
20 December 31, 2008, an amount equal to the amount of
21 insurance premium expenses and costs otherwise allowed
22 as a deduction in computing base income, and that were
23 paid, accrued, or incurred, directly or indirectly, to
24 a person who would be a member of the same unitary
25 business group but for the fact that the person is
26 prohibited under Section 1501(a)(27) from being

HB3310- 90 -LRB104 10872 HLH 20954 b
1 included in the unitary business group because he or

5 shall be reduced to the extent that dividends were
6 included in base income of the unitary group for the
7 same taxable year and received by the taxpayer or by a
8 member of the taxpayer's unitary business group
9 (including amounts included in gross income under
10 Sections 951 through 964 of the Internal Revenue Code

12 of the Internal Revenue Code) with respect to the
13 stock of the same person to whom the premiums and costs
14 were directly or indirectly paid, incurred, or
15 accrued. The preceding sentence does not apply to the

18 203(d)(2)(D-7) or Section 203(d)(2)(D-8) of this Act;
19            (D-10) An amount equal to the credit allowable to

24 by Section 801 of the Internal Revenue Code, life
25 insurance company taxable income, plus the amount of
26 distribution from pre-1984 policyholder surplus

HB3310- 102 -LRB104 10872 HLH 20954 b
1 accounts as calculated under Section 815a of the

12 a real estate investment trust subject to the tax

15            (E) Consolidated corporations. In the case of a
16 corporation which is a member of an affiliated group
17 of corporations filing a consolidated income tax
18 return for the taxable year for federal income tax
19 purposes, taxable income determined as if such
20 corporation had filed a separate return for federal
21 income tax purposes for the taxable year and each
22 preceding taxable year for which it was a member of an
23 affiliated group. For purposes of this subparagraph,
24 the taxpayer's separate taxable income shall be
25 determined as if the election provided by Section
26 243(b)(2) of the Internal Revenue Code had been in

HB3310- 103 -LRB104 10872 HLH 20954 b
1 effect for all such years;
2            (F) Cooperatives. In the case of a cooperative
3 corporation or association, the taxable income of such
4 organization determined in accordance with the
5 provisions of Section 1381 through 1388 of the
6 Internal Revenue Code, but without regard to the
7 prohibition against offsetting losses from patronage
8 activities against income from nonpatronage
9 activities; except that a cooperative corporation or
10 association may make an election to follow its federal
11 income tax treatment of patronage losses and
12 nonpatronage losses. In the event such election is
13 made, such losses shall be computed and carried over
14 in a manner consistent with subsection (a) of Section
15 207 of this Act and apportioned by the apportionment
16 factor reported by the cooperative on its Illinois
17 income tax return filed for the taxable year in which
18 the losses are incurred. The election shall be
19 effective for all taxable years with original returns
20 due on or after the date of the election. In addition,
21 the cooperative may file an amended return or returns,
22 as allowed under this Act, to provide that the
23 election shall be effective for losses incurred or
24 carried forward for taxable years occurring prior to
25 the date of the election. Once made, the election may
26 only be revoked upon approval of the Director. The

HB3310- 104 -LRB104 10872 HLH 20954 b
1 Department shall adopt rules setting forth
2 requirements for documenting the elections and any
3 resulting Illinois net loss and the standards to be
4 used by the Director in evaluating requests to revoke
5 elections. Public Act 96-932 is declaratory of
6 existing law;
7            (G) Subchapter S corporations. In the case of: (i)
8 a Subchapter S corporation for which there is in
9 effect an election for the taxable year under Section
10 1362 of the Internal Revenue Code, the taxable income
11 of such corporation determined in accordance with
12 Section 1363(b) of the Internal Revenue Code, except
13 that taxable income shall take into account those
14 items which are required by Section 1363(b)(1) of the
15 Internal Revenue Code to be separately stated; and
16 (ii) a Subchapter S corporation for which there is in
17 effect a federal election to opt out of the provisions
18 of the Subchapter S Revision Act of 1982 and have
19 applied instead the prior federal Subchapter S rules
20 as in effect on July 1, 1982, the taxable income of
21 such corporation determined in accordance with the
22 federal Subchapter S rules as in effect on July 1,
23 1982; and
24            (H) Partnerships. In the case of a partnership,
25 taxable income determined in accordance with Section
26 703 of the Internal Revenue Code, except that taxable

HB3310- 105 -LRB104 10872 HLH 20954 b
1 income shall take into account those items which are
2 required by Section 703(a)(1) to be separately stated
3 but which would be taken into account by an individual
4 in calculating his taxable income.
5        (3) Recapture of business expenses on disposition of
6 asset or business. Notwithstanding any other law to the
7 contrary, if in prior years income from an asset or
8 business has been classified as business income and in a
9 later year is demonstrated to be non-business income, then
10 all expenses, without limitation, deducted in such later
11 year and in the 2 immediately preceding taxable years
12 related to that asset or business that generated the
13 non-business income shall be added back and recaptured as
14 business income in the year of the disposition of the
15 asset or business. Such amount shall be apportioned to
16 Illinois using the greater of the apportionment fraction
17 computed for the business under Section 304 of this Act
18 for the taxable year or the average of the apportionment
19 fractions computed for the business under Section 304 of
20 this Act for the taxable year and for the 2 immediately
21 preceding taxable years.
22    (f) Valuation limitation amount.
23        (1) In general. The valuation limitation amount
24 referred to in subsections (a)(2)(G), (c)(2)(I) and
25 (d)(2)(E) is an amount equal to:

HB3310- 106 -LRB104 10872 HLH 20954 b
1            (A) The sum of the pre-August 1, 1969 appreciation
2 amounts (to the extent consisting of gain reportable
3 under the provisions of Section 1245 or 1250 of the
4 Internal Revenue Code) for all property in respect of
5 which such gain was reported for the taxable year;
6 plus
7            (B) The lesser of (i) the sum of the pre-August 1,
8 1969 appreciation amounts (to the extent consisting of
9 capital gain) for all property in respect of which
10 such gain was reported for federal income tax purposes
11 for the taxable year, or (ii) the net capital gain for
12 the taxable year, reduced in either case by any amount
13 of such gain included in the amount determined under
14 subsection (a)(2)(F) or (c)(2)(H).
15        (2) Pre-August 1, 1969 appreciation amount.
16            (A) If the fair market value of property referred
17 to in paragraph (1) was readily ascertainable on
18 August 1, 1969, the pre-August 1, 1969 appreciation
19 amount for such property is the lesser of (i) the
20 excess of such fair market value over the taxpayer's
21 basis (for determining gain) for such property on that
22 date (determined under the Internal Revenue Code as in
23 effect on that date), or (ii) the total gain realized
24 and reportable for federal income tax purposes in
25 respect of the sale, exchange or other disposition of
26 such property.

HB3310- 107 -LRB104 10872 HLH 20954 b
1            (B) If the fair market value of property referred
2 to in paragraph (1) was not readily ascertainable on
3 August 1, 1969, the pre-August 1, 1969 appreciation
4 amount for such property is that amount which bears
5 the same ratio to the total gain reported in respect of
6 the property for federal income tax purposes for the
7 taxable year, as the number of full calendar months in
8 that part of the taxpayer's holding period for the
9 property ending July 31, 1969 bears to the number of
10 full calendar months in the taxpayer's entire holding
11 period for the property.
12            (C) The Department shall prescribe such
13 regulations as may be necessary to carry out the
14 purposes of this paragraph.
15    (g) Double deductions. Unless specifically provided
16otherwise, nothing in this Section shall permit the same item
17to be deducted more than once.
18    (h) Legislative intention. Except as expressly provided by
19this Section there shall be no modifications or limitations on
20the amounts of income, gain, loss or deduction taken into
21account in determining gross income, adjusted gross income or
22taxable income for federal income tax purposes for the taxable
23year, or in the amount of such items entering into the
24computation of base income and net income under this Act for

HB3310- 108 -LRB104 10872 HLH 20954 b
