(I) Special rules with respect to certain acquisitive reorganizations described in paragraph (1)(A), (1)(B), (1)(C), and (1)(D)

(i) In general

A merger, consolidation, acquisition, or transfer which is described in clause (ii) shall not be treated as a merger, consolidation, acquisition, or transfer described in paragraph (1)(A), (1)(B), (1)(C), or (1)(D).

(ii) Transactions described

A merger, consolidation, acquisition, or transfer is described in this clause if—

(I)

such merger, consolidation, acquisition, or transfer is, or is treated as, the acquisition of the stock or assets of another corporation,

(II)

such merger, consolidation, acquisition, or transfer is not excepted under clause (iii), and

(III)

the combined average annual gross receipts of the acquiring corporation and the acquired corporation for the 3-taxable year period which precedes the taxable year in which the merger, consolidation, acquisition, or transfer is completed exceeds $500,000,000.

(iii) Exceptions

A merger, consolidation, acquisition, or transfer is excepted under this clause if—

(I)

either the acquiring corporation or the acquired corporation controls the other immediately before (and, if both corporations continue to exist, after) the merger, consolidation, acquisition, or transfer (as the case may be),

(II)

any other corporation controls both the acquiring corporation and the acquired corporation immediately before (and, if both corporations continue to exist, after) the merger, consolidation, acquisition, or transfer (as the case may be), or

(III)

either the acquiring corporation or the acquired corporation meets the gross receipts test of section 448(c)(1) for the taxable year in which the merger, consolidation, acquisition, or transfer is completed.

(iv) Aggregation and other special rules

Rules similar to the rules of paragraphs (2) and (3) of section 448(c) shall apply for purposes of clause (i)(II), except that (unless otherwise provided by the Secretary) the rules of section 448(c)(2) shall not apply in determining the average annual gross receipts of the acquired corporation.

(v) Inflation adjustment

In the case of any taxable year beginning after 2026, the dollar amount in clause (ii)(III) shall be increased by an amount equal to—

(I)

such dollar amount, multiplied by

(II)

the cost-of-living adjustment determined under section 1(f)(3) for the calendar year in which such taxable year begins, determined by substituting calendar year 2025 for calendar year 2016 in subparagraph (A)(ii) thereof.

If any amount as increased under the preceding sentence is not a multiple of $1,000,000, such amount shall be rounded to the nearest multiple of $1,000,000.

(vi) Regulations and guidance

The Secretary may prescribe such regulations and other guidance as are necessary or appropriate to carry out, and to prevent the abuse of the purposes of, this subparagraph, including rules—

(I)

to prevent the avoidance of the application of this subparagraph through the use of a series of transactions designed and executed as parts of a unitary plan, and

(II)

for the nonapplication of the rules of clause (i) where such nonapplication is consistent with the purposes of this subparagraph.

(b) Transfers to corporations controlled by transferors

Section 351 is amended by redesignating subsection (h) as subsection (i) and by inserting after subsection (g) the following new subsection:

(h) Special rule with respect to multiple transferors

(1) In general

(2) Exception

Clause (i) shall not apply if—

(A)

such persons control the corporation to which the property is transferred immediately before the transfer,

(B)

another corporation controls all such persons and the corporation to which the property is transferred immediately before the transfer, or

(C)

all such persons meet the gross receipts test of section 448(c)(1) for the taxable year in which the transfer is made.

(3) Aggregation and other special rules

Rules similar to the rules of paragraphs (2) and (3) of section 448(c) shall apply for purposes of paragraph (1).

In the case of any taxable year beginning after 2026, the dollar amount in paragraph (1) shall be increased by an amount equal to—

the cost-of-living adjustment determined under section 1(f)(3) for the calendar year in which such taxable year begins, determined by substituting calendar year 2025 for calendar year 2016 in subparagraph (A)(ii) thereof.

If any amount as increased under the preceding sentence is not a multiple of $1,000,000, such amount shall be rounded to the nearest multiple of $1,000,000.

(5) Regulations and guidance

The Secretary may prescribe such regulations and other guidance as are necessary or appropriate to carry out, and to prevent the abuse of the purposes of, this subparagraph, including rules—

(A)

to prevent the avoidance of the application of this subsection through the use of a series of transactions designed and executed as parts of a unitary plan, and

for the nonapplication of the rules of paragraph (1) where such nonapplication is consistent with the purposes of this subsection.
