(less than $5,000 for taxable years beginning before January 1, 1970) see section 3. The tax imposed is upon taxable income (determined by subtracting the allowable deductions from gross income). The tax is determined in accordance with the table contained in section 1. See subparagraph (2) of this paragraph for reference guides to the appropriate table for taxable years beginning on or after January 1, 1964, and before January 1, 1965, taxable years beginning after December 31, 1964, and before January 1, 1971, and taxable years beginning after December 31, 1970. In certain cases credits are allowed against the amount of the tax. See part IV (section 31 and following), subchapter A, chapter 1 of the Code. In general, the tax is payable upon the basis of returns rendered by persons liable therefor (subchapter A (sections 6001 and following), chapter 61 of the Code) or at the source of the income by

Taxable years beginning in 1964

withholding. For the computation of tax in the case of a joint return of a husband and wife, or a return of a surviving spouse, for taxable years beginning before January 1, 1971, see section 2. The computation of tax in such a case for taxable years beginning after December 31, 1970, is determined in accordance with the table contained in section 1(a) as amended by the Tax Reform Act of 1969. For other rates of tax on individuals, see section 5(a). For the imposition of an additional tax for the calendar years 1968, 1969, and 1970, see section 51(a).

(2)(i) For taxable years beginning on or after January 1, 1964, the tax imposed upon a single individual, a head of a household, a married individual filing a separate return, and estates and trusts is the tax imposed by section 1 determined in accordance with the appropriate table contained in the following subsection of section 1:

(ii) For taxable years beginning after December 31, 1970, the tax imposed by section 1(d), as amended by the Tax Reform Act of 1969, shall apply to the income effectively connected with the conduct of a trade or business in the United States by a married alien individual who is a nonresident of the United States for all or part of the taxable year or by a foreign estate or trust. For such years the tax imposed by section 1(c), as amended by such Act, shall apply to the income effectively connected with the conduct of a trade or business in the United States by an unmarried alien individual (other than a surviving spouse) who is a nonresident of the United States for all or part of the taxable year. See paragraph (b)(2) of §1.871-8.

(3) The income tax imposed by section 1 upon any amount of taxable income is computed by adding to the income tax for the bracket in which that

amount falls in the appropriate table in section 1 the income tax upon the excess of that amount over the bottom of the bracket at the rate indicated in such table.

(4) The provisions of section 1 of the Code, as amended by the Tax Reform Act of 1969, and of this paragraph may be illustrated by the following examples:

Example 1. A, an unmarried individual, had taxable income for the calendar year 1964 of $15,750. Accordingly, the tax upon such taxable income would be $4,507.50, computed as follows from the table in section 1(a)(1): Tax on $14,000 (from table)

Tax on $1,750 (at 41 percent as determined from the table)

Total tax on $15,750

$3,790.00

717.50

4,507.50

Example 2. Assume the same facts as in example (1), except the figures are for the calendar year 1965. The tax upon such taxable income would be $4,232.50, computed as follows from the table in section 1(a)(2):

(b) Citizens or residents of the United States liable to tax. In general, all citizens of the United States, wherever resident, and all resident alien individuals are liable to the income taxes imposed by the Code whether the income is received from sources within or without the United States. Pursuant to section 876, a nonresident alien individual who is a bona fide resident of Puerto Rico during the entire taxable year is, except as provided in section 933 with respect to Puerto Rican source income, subject to taxation in the same manner as a resident alien individual. As to tax on nonresident alien individuals, see sections 871 and 877.

(c) Who is a citizen. Every person born or naturalized in the United States and subject to its jurisdiction is a citizen. For other rules governing the acquisition of citizenship, see chapters 1 and 2 of title III of the Immigration and Nationality Act (8 U.S.C. 1401-1459). For rules governing loss of citizenship, see sections 349 to 357, inclusive, of such Act (8 U.S.C. 1481-1489), Schneider v. Rusk, (1964) 377 U.S. 163, and Rev. Rul. 70-506, C.B. 1970-2, 1. For rules pertaining to persons who are nationals but not citizens at birth, e.g., a person born in American Samoa, see section 308 of such Act (8 U.S.C. 1408). For special rules applicable to certain expatriates who have lost citizenship with a principal purpose of avoiding certain taxes, see section 877. A foreigner who has filed his declaration of intention of becoming a citizen but who has not yet been admitted to citizenship by a final

order of a naturalization court is an alien.

§1.1-2 Limitation on tax.

(a) Taxable years ending before January 1, 1971. For taxable years ending before January 1, 1971, the tax imposed by section 1 (whether by subsection (a) or subsection (b) thereof) shall not exceed 87 percent of the taxable income for the taxable year. For purposes of determining this limitation the tax under section 1 (a) or (b) and the tax at the 87-percent rate shall each be computed before the allowance of any credits against the tax. Where the alternative tax on capital gains is imposed under section 1201(b), the 87-percent limitation shall apply only to the partial tax computed on the taxable income reduced by 50 percent of the excess of net long-term capital gains over net shortterm capital losses. Where, for purposes of computations under the income averaging provisions, section 1201(b) is treated as imposing the alternative tax on capital gains computed under section 1304(e)(2), the 87-percent limitation shall apply only to the tax equal to the tax imposed by section 1, reduced by the amount of the tax imposed by section 1 which is attributable to capital gain net income for the computation year.

(b) Taxable years beginning after December 31, 1970. If, for any taxable year beginning after December 31, 1970, an individual has earned taxable income which exceeds his taxable income as defined by section 1348, the tax imposed by section 1, as amended by the Tax Reform Act of 1969, shall not exceed the sum computed under the provisions of section 1348. For imposition of minimum tax for tax preferences see sections 56 through 58.

For computation of the tax for a taxable year during which a change in the

tax rates occurs, see section 21 and the regulations thereunder.

§1.1(h)-1 Capital gains look-through

rule for sales or exchanges of interests in a partnership, S corporation, or trust.

(a) In general. When an interest in a partnership held for more than one year is sold or exchanged, the transferor may recognize ordinary income (e.g., under section 751(a)), collectibles gain, section 1250 capital gain, and residual long-term capital gain or loss. When stock in an S corporation held for more than one year is sold or exchanged, the transferor may recognize ordinary income (e.g., under sections 304, 306, 341, 1254), collectibles gain, and residual long-term capital gain or loss. When an interest in a trust held for more than one year is sold or exchanged, a transferor who is not treated as the owner of the portion of the trust attributable to the interest sold or exchanged (sections 673 through 679) (a non-grantor transferor) may recognize collectibles gain and residual longterm capital gain or loss.

(b) Look-through capital gain—(1) In general. Look-through capital gain is the share of collectibles gain allocable to an interest in a partnership, S corporation, or trust, plus the share of section 1250 capital gain allocable to an interest in a partnership, determined under paragraphs (b)(2) and (3) of this section.

(2) Collectibles gain—(i) Definition. For purposes of this section, collectibles gain shall be treated as gain from the sale or exchange of a collectible (as defined in section 408(m) without regard to section 408(m)(3)) that is a capital asset held for more than 1 year.

(ii) Share of collectibles gain allocable to an interest in a partnership, S corporation, or a trust. When an interest in a partnership, S corporation, or trust held for more than one year is sold or exchanged in a transaction in which all realized gain is recognized, the transferor shall recognize as collectibles gain the amount of net gain (but not net loss) that would be allocated to that partner (taking into account any remedial allocation under §1.704-3(d)),

shareholder, or beneficiary (to the extent attributable to the portion of the partnership interest, S corporation stock, or trust interest transferred that was held for more than one year) if the partnership, S corporation, or trust transferred all of its collectibles for cash equal to the fair market value of the assets in a fully taxable transaction immediately before the transfer of the interest in the partnership, S corporation, or trust. If less than all of the realized gain is recognized upon the sale or exchange of an interest in a partnership, S corporation, or trust, the same methodology shall apply to determine the collectibles gain recognized by the transferor, except that the partnership, S corporation, or trust shall be treated as transferring only a proportionate amount of each of its collectibles determined as a fraction that is the amount of gain recognized in the sale or exchange over the amount of gain realized in the sale or exchange. With respect to the transfer of an interest in a trust, this paragraph (b)(2) applies only to transfers by nongrantor transferors (as defined in paragraph (a) of this section). This paragraph (b)(2) does not apply to a transaction that is treated, for Federal income tax purposes, as a redemption of an interest in a partnership, S corporation, or trust.

(3) Section 1250 capital gain—(i) Definition. For purposes of this section, section 1250 capital gain means the capital gain (not otherwise treated as ordinary income) that would be treated as ordinary income if section 1250(b)(1) included all depreciation and the applicable percentage under section 1250(a) were 100 percent.

(ii) Share of section 1250 capital gain allocable to interest in partnership. When an interest in a partnership held for more than one year is sold or exchanged in a transaction in which all realized gain is recognized, there shall be taken into account under section 1(h)(7)(A)(i) in determining the partner's unrecaptured section 1250 gain the amount of section 1250 capital gain that would be allocated (taking into account any remedial allocation under §1.704-3(d)) to that partner (to the extent attributable to the portion of the partnership interest transferred that

was held for more than one year) if the partnership transferred all of its section 1250 property in a fully taxable transaction for cash equal to the fair market value of the assets immediately before the transfer of the interest in the partnership. If less than all of the realized gain is recognized upon the sale or exchange of an interest in a partnership, the same methodology shall apply to determine the section 1250 capital gain recognized by the transferor, except that the partnership shall be treated as transferring only a proportionate amount of each section 1250 property determined as a fraction that is the amount of gain recognized in the sale or exchange over the amount of gain realized in the sale or exchange. This paragraph (b)(3) does not apply to a transaction that is treated, for Federal income tax purposes, as a redemption of a partnership interest.

(iii) Limitation with respect to net section 1231 gain. In determining a transferor partner's net section 1231 gain (as defined in section 1231(c)(3)) for purposes of section 1(h)(7)(B), the transferor partner's allocable share of section 1250 capital gain in partnership property shall not be treated as section 1231 gain, regardless of whether the partnership property is used in the trade or business (as defined in section 1231(b)).

(c) Residual long-term capital gain or loss. The amount of residual long-term capital gain or loss recognized by a partner, shareholder of an S corporation, or beneficiary of a trust on account of the sale or exchange of an interest in a partnership, S corporation, or trust shall equal the amount of long-term capital gain or loss that the partner would recognize under section 741, that the shareholder would recognize upon the sale or exchange of stock of an S corporation, or that the beneficiary would recognize upon the sale or exchange of an interest in a trust (pre-look-through long-term capital gain or loss) minus the amount of lookthrough capital gain determined under paragraph (b) of this section.

(d) Special rule for tiered entities. In determining whether a partnership, S corporation, or trust has gain from collectibles, such partnership, S corpora

tion, or trust shall be treated as owning its proportionate share of the collectibles of any partnership, S corporation, or trust in which it owns an interest either directly or indirectly through a chain of such entities. In determining whether a partnership has section 1250 capital gain, such partnership shall be treated as owning its proportionate share of the section 1250 property of any partnership in which it owns an interest, either directly or indirectly through a chain of partnerships.

(e) Notification requirements. Reporting rules similar to those that apply to the partners and the partnership under section 751(a) shall apply in the case of sales or exchanges of interests in a partnership, S corporation, or trust that cause holders of such interests to recognize collectibles gain and in the case of sales or exchanges of interests in a partnership that cause holders of such interests to recognize section 1250 capital gain. See §1.751-1(a)(3).

(f) Examples. The following examples illustrate the requirements of this section:

Example 1. Collectibles gain. (i) A and B are equal partners in a personal service partnership (PRS). B transfers B's interest in PRS to T for $15,000 when PRS's balance sheet (reflecting a cash receipts and disbursements method of accounting) is as follows:

$10,000 ($9,000 plus $1,000, B's share of partnership liabilities). None of the property owned by PRS is section 704(c) property. The total amount realized by B is $16,000, consisting of the cash received, $15,000, plus $1,000, B's share of the partnership liabilities assumed by T. See section 752. B's undivided one-half interest in PRS includes a one-half interest in the partnership's unrealized receivables and a one-half interest in the partnership's collectibles.

(iii) If PRS were to sell all of its section 751 property in a fully taxable transaction for cash equal to the fair market value of the assets immediately prior to the transfer of B's partnership interest to T, B would be allocated $7,000 of ordinary income from the sale of PRS's unrealized receivables. Therefore, B will recognize $7,000 of ordinary income with respect to the unrealized receivables. The difference between the amount of capital gain or loss that the partner would realize in the absence of section 751 ($6,000) and the amount of ordinary income or loss determined under §1.751-1(a)(2) ($7,000) is the partner's capital gain or loss on the sale of the partnership interest under section 741. In this case, the transferor has a $1,000 prelook-through long-term capital loss.

(iv) If PRS were to sell all of its collectibles in a fully taxable transaction for cash equal to the fair market value of the assets immediately prior to the transfer of B's partnership interest to T, B would be allocated $1,000 of gain from the sale of the collectibles. Therefore, B will recognize $1,000 of collectibles gain on account of the collectibles held by PRS.

(v) The difference between the transferor's pre-look-through long-term capital gain or loss ($1,000) and the look-through capital gain determined under this section ($1,000) is the transferor's residual long-term capital gain or loss on the sale of the partnership interest. Under these facts, B will recognize a $2,000 residual long-term capital loss on account of the sale or exchange of the interest in PRS.

Example 2. Special allocations. Assume the same facts as in Example 1, except that under the partnership agreement, all gain from the sale of the collectibles is specially allocated to B, and B transfers B's interest to T for $16,000. All items of income, gain, loss, or deduction of PRS, other than the gain from the collectibles, are divided equally between A and B. Under these facts, B's amount realized is $17,000, consisting of the cash received, $16,000, plus $1,000, B's share of the partnership liabilities assumed by T. See section 752. B will recognize $7,000 of ordinary income with respect to the unrealized receivables (determined under §1.751-1(a)(2)). Accordingly, B's pre-look-through long-term capital gain would be $0. If PRS were to sell all of its collectibles in a fully taxable transaction for cash equal to the fair market

value of the assets immediately prior to the transfer of B's partnership interest to T, B would be allocated $2,000 of gain from the sale of the collectibles. Therefore, B will recognize $2,000 of collectibles gain on account of the collectibles held by PRS. B will recognize a $2,000 residual long-term capital loss on account of the sale of B's interest in PRS. Example 3. Net collectibles loss ignored. Assume the same facts as in Example 1, except that the collectibles held by PRS have an adjusted basis of $3,000 and a fair market value of $1,000, and the other capital assets have an adjusted basis of $4,000 and a fair market value of $4,000. (The total adjusted basis and fair market value of the partnership's capital assets are the same as in Example 1.) If PRS were to sell all of its collectibles in a fully taxable transaction for cash equal to the fair market value of the assets immediately prior to the transfer of B's partnership interest to T, B would be allocated $1,000 of loss from the sale of the collectibles. Because none of the gain from the sale of the interest in PRS is attributable to unrealized appreciation in the value of collectibles held by PRS, the net loss in collectibles held by PRS is not recognized at the time B transfers the interest in PRS. B will recognize $7,000 of ordinary income (determined under §1.7511(a)(2)) and a $1,000 long-term capital loss on account of the sale of B's interest in PRS.

Example 4. Collectibles gain in an S corporation. (i) A corporation (X) has always been an S corporation and is owned by individuals A, B, and C. In 1996, X invested in antiques. Subsequent to their purchase, the antiques appreciated in value by $300. A owns onethird of the shares of X stock and has held that stock for more than one year. A's adjusted basis in the X stock is $100. If A were to sell all of A's X stock to T for $150, A would realize $50 of pre-look-through longterm capital gain.

(ii) If X were to sell its antiques in a fully taxable transaction for cash equal to the fair market value of the assets immediately before the transfer to T, A would be allocated $100 of gain on account of the sale. Therefore, A will recognize $100 of collectibles gain (look-through capital gain) on account of the collectibles held by X.

(iii) The difference between the transferor's pre-look-through long-term capital gain or loss ($50) and the look-through capital gain determined under this section ($100) is the transferor's residual long-term capital gain or loss on the sale of the S corporation stock. Under these facts, A will recognize $100 of collectibles gain and a $50 residual long-term capital loss on account of the sale of A's interest in X.

Example 5. Sale or exchange of partnership interest where part of the interest has a shortterm holding period. (i) A, B, and C form an equal partnership (PRS). In connection with the formation, A contributes $5,000 in cash
