SECTION 4. DEFINITIONS

The following definitions apply solely for purposes of this revenue procedure.

election for the qualifying ESB sole proprietorship income, gain, loss, and deduction that is allowed in calculating the taxpayer’s applicable 2008 NOL.

(4) In determining whether a partnership, S corporation, or sole proprietorship qualifies as an ESB, the gross receipts test applies at the partnership, corporate, or sole proprietorship level. The aggregation rules of § 448(c)(2) apply to determine whether the partnership, S corporation, or sole proprietorship meets the gross receipts test of § 448(c).

(5) The amount of the taxpayer’s applicable 2008 NOL that the taxpayer may carry back under §172(b)(1)(H) is limited to the lesser of:

(a) The taxpayer’s items of income, gain, loss or deduction that are allowed in calculating the taxpayer’s applicable 2008 NOL and are from one or more partnerships, S corporations or sole proprietorships that qualify as ESBs, or

(b) The taxpayer’s applicable 2008 NOL.

(6) Examples . (a) Example 1 . Partnerships A, B, and C have average annual gross receipts of $10 million, $12 million, and $14 million, respectively. Partner T owns a 40% interest in each partnership. None of the partnerships is required to be aggregated with any other entity for purposes of the aggregation rules of § 448(c)(2). Subject to the limitations in section 4.04(5) of this revenue procedure, Partner T may apply its election under § 172(b)(1)(H) to the portion of its applicable 2008 NOL attributable to its distributive share of the income, gain, loss, and deduction of each of Partnerships A, B, and C.

(b) Example 2 . The facts are the same as in Ex- ample 1, except that Partnerships A and B are under common control within the meaning of § 52(b)(1). Accordingly, Partnerships A and B are treated as one person under the aggregation rules of § 448(c)(2). Because the aggregated average annual gross receipts of Partnerships A and B exceed $15 million, Partnerships A and B do not qualify as ESBs. Partner T may not apply its election under § 172(b)(1)(H) to the portion of its applicable 2008 NOL attributable to its distributive share of the income, gain, loss, and deduction of Partnerships A and B. However, subject to the limitations in section 4.04(5) of this revenue procedure, Partner T may apply its election under § 172(b)(1)(H) to the portion of its applicable 2008 NOL attributable to its distributive share of income, gain, loss, and deduction of Partnership C.
