-STATUTE-
    (a) Net earnings from self-employment
      The term "net earnings from self-employment" means the gross
    income derived by an individual from any trade or business carried
    on by such individual, less the deductions allowed by this subtitle
    which are attributable to such trade or business, plus his
    distributive share (whether or not distributed) of income or loss
    described in section 702(a)(8) from any trade or business carried
    on by a partnership of which he is a member; except that in
    computing such gross income and deductions and such distributive
    share of partnership ordinary income or loss - 
        (1) there shall be excluded rentals from real estate and from
      personal property leased with the real estate (including such
      rentals paid in crop shares) together with the deductions
      attributable thereto, unless such rentals are received in the
      course of a trade or business as a real estate dealer; except
      that the preceding provisions of this paragraph shall not apply
      to any income derived by the owner or tenant of land if (A) such
      income is derived under an arrangement, between the owner or
      tenant and another individual, which provides that such other
      individual shall produce agricultural or horticultural
      commodities (including livestock, bees, poultry, and fur-bearing
      animals and wildlife) on such land, and that there shall be
      material participation by the owner or tenant (as determined
      without regard to any activities of an agent of such owner or
      tenant) in the production or the management of the production of
      such agricultural or horticultural commodities, and (B) there is
      material participation by the owner or tenant (as determined
      without regard to any activities of an agent of such owner or
      tenant) with respect to any such agricultural or horticultural
      commodity;
        (2) there shall be excluded dividends on any share of stock,
      and interest on any bond, debenture, note, or certificate, or
      other evidence of indebtedness, issued with interest coupons or
      in registered form by any corporation (including one issued by a
      government or political subdivision thereof), unless such
      dividends and interest are received in the course of a trade or
      business as a dealer in stocks or securities;
        (3) there shall be excluded any gain or loss - 
          (A) which is considered as gain or loss from the sale or
        exchange of a capital asset,
          (B) from the cutting of timber, or the disposal of timber,
        coal, or iron ore, if section 631 applies to such gain or loss,

        disposition of property if such property is neither - 
            (i) stock in trade or other property of a kind which would
          properly be includible in inventory if on hand at the close
          of the taxable year, nor
            (ii) property held primarily for sale to customers in the
          ordinary course of the trade or business;

        (4) the deduction for net operating losses provided in section
      172 shall not be allowed;
        (5) if - 
          (A) any of the income derived from a trade or business (other
        than a trade or business carried on by a partnership) is
        community income under community property laws applicable to
        such income, all of the gross income and deductions
        attributable to such trade or business shall be treated as the
        gross income and deductions of the husband unless the wife
        exercises substantially all of the management and control of
        such trade or business, in which case all of such gross income
        and deductions shall be treated as the gross income and
        deductions of the wife; and
          (B) any portion of a partner's distributive share of the
        ordinary income or loss from a trade or business carried on by
        a partnership is community income or loss under the community
        property laws applicable to such share, all of such
        distributive share shall be included in computing the net
        earnings from self-employment of such partner, and no part of
        such share shall be taken into account in computing the net
        earnings from self-employment of the spouse of such partner;

      151 shall not be allowed;

      the performance of service described in subsection (c)(4) without
      regard to section 107 (relating to rental value of parsonages),
      section 119 (relating to meals and lodging furnished for the
      convenience of the employer), and section 911 (relating to
      citizens or residents of the United States living abroad), but
      shall not include in such net earnings from self-employment the
      rental value of any parsonage or any parsonage allowance (whether
      or not excludable under section 107) provided after the
      individual retires, or any other retirement benefit received by
      such individual from a church plan (as defined in section 414(e))
      after the individual retires;
        (9) the exclusion from gross income provided by section 931
      shall not apply;
        (10) there shall be excluded amounts received by a partner
      pursuant to a written plan of the partnership, which meets such
      requirements as are prescribed by the Secretary, and which
      provides for payments on account of retirement, on a periodic
      basis, to partners generally or to a class or classes of
      partners, such payments to continue at least until such partner's
      death, if - 
          (A) such partner rendered no services with respect to any
        trade or business carried on by such partnership (or its
        successors) during the taxable year of such partnership (or its
        successors), ending within or with his taxable year, in which
        such amounts were received, and
          (B) no obligation exists (as of the close of the
        partnership's taxable year referred to in subparagraph (A))
        from the other partners to such partner except with respect to
        retirement payments under such plan, and
          (C) such partner's share, if any, of the capital of the
        partnership has been paid to him in full before the close of
        the partnership's taxable year referred to in subparagraph (A);

        (11) the exclusion from gross income provided by section
      911(a)(1) shall not apply;
        (12) in lieu of the deduction provided by section 164(f)
      (relating to deduction for one-half of self-employment taxes),
      there shall be allowed a deduction equal to the product of - 
          (A) the taxpayer's net earnings from self-employment for the
        taxable year (determined without regard to this paragraph), and
          (B) one-half of the sum of the rates imposed by subsections
        (a) and (b) of section 1401 for such year;

        (13) there shall be excluded the distributive share of any item
      of income or loss of a limited partner, as such, other than
      guaranteed payments described in section 707(c) to that partner
      for services actually rendered to or on behalf of the partnership
      to the extent that those payments are established to be in the
      nature of remuneration for those services;
        (14) in the case of church employee income, the special rules
      of subsection (j)(1) shall apply; and
        (15) in the case of a member of an Indian tribe, the special
      rules of section 7873 (relating to income derived by Indians from
      exercise of fishing rights) shall apply.

    If the taxable year of a partner is different from that of the
    partnership, the distributive share which he is required to include
    in computing his net earnings from self-employment shall be based
    on the ordinary income or loss of the partnership for any taxable
    year of the partnership ending within or with his taxable year. In
    the case of any trade or business which is carried on by an
    individual or by a partnership and in which, if such trade or
    business were carried on exclusively by employees, the major
    portion of the services would constitute agricultural labor as
    defined in section 3121(g) - 
        (i) in the case of an individual, if the gross income derived
      by him from such trade or business is not more than $2,400, the
      net earnings from self-employment derived by him from such trade
      or business may, at his option, be deemed to be 66 2/3  percent
      of such gross income; or
        (ii) in the case of an individual, if the gross income derived
      by him from such trade or business is more than $2,400 and the
      net earnings from self-employment derived by him from such trade
      or business (computed under this subsection without regard to
      this sentence) are less than $1,600, the net earnings from
      self-employment derived by him from such trade or business may,
      at his option, be deemed to be $1,600; and
        (iii) in the case of a member of a partnership, if his
      distributive share of the gross income of the partnership derived
      from such trade or business (after such gross income has been
      reduced by the sum of all payments to which section 707(c)
      applies) is not more than $2,400, his distributive share of
      income described in section 702(a)(8) derived from such trade or
      business may, at his option, be deemed to be an amount equal to
      66 2/3  percent of his distributive share of such gross income
      (after such gross income has been so reduced); or
        (iv) in the case of a member of a partnership, if his
      distributive share of the gross income of the partnership derived
      from such trade or business (after such gross income has been
      reduced by the sum of all payments to which section 707(c)
      applies) is more than $2,400 and his distributive share (whether
      or not distributed) of income described in section 702(a)(8)
      derived from such trade or business (computed under this
      subsection without regard to this sentence) is less than $1,600,
      his distributive share of income described in section 702(a)(8)
      derived from such trade or business may, at his option, be deemed
      to be $1,600.

    For purposes of the preceding sentence, gross income means - 
        (v) in the case of any such trade or business in which the
      income is computed under a cash receipts and disbursements
      method, the gross receipts from such trade or business reduced by
      the cost or other basis of property which was purchased and sold
      in carrying on such trade or business, adjusted (after such
      reduction) in accordance with the provisions of paragraphs (1)
      through (7) and paragraph (9) of this subsection; and
        (vi) in the case of any such trade or business in which the
      income is computed under an accrual method, the gross income from
      such trade or business, adjusted in accordance with the
      provisions of paragraphs (1) through (7) and paragraph (9) of
      this subsection;

    and, for purposes of such sentence, if an individual (including a
    member of a partnership) derives gross income from more than one
    such trade or business, such gross income (including his
    distributive share of the gross income of any partnership derived
    from any such trade or business) shall be deemed to have been
    derived from one trade or business.
      The preceding sentence and clauses (i) through (iv) of the second
    preceding sentence shall also apply in the case of any trade or
    business (other than a trade or business specified in such second
    preceding sentence) which is carried on by an individual who is
    self-employed on a regular basis as defined in subsection (h), or
    by a partnership of which an individual is a member on a regular
    basis as defined in subsection (h), but only if such individual's
    net earnings from self-employment as determined without regard to
    this sentence in the taxable year are less than $1,600 and less
    than 66 2/3  percent of the sum (in such taxable year) of such
    individual's gross income derived from all trades or businesses
    carried on by him and his distributive share of the income or loss
    from all trades or businesses carried on by all the partnerships of
    which he is a member; except that this sentence shall not apply to
    more than 5 taxable years in the case of any individual, and in no
    case in which an individual elects to determine the amount of his
    net earnings from self-employment for a taxable year under the
    provisions of the two preceding sentences with respect to a trade
    or business to which the second preceding sentence applies and with
    respect to a trade or business to which this sentence applies shall
    such net earnings for such year exceed $1,600.
    (b) Self-employment income
      The term "self-employment income" means the net earnings from
    self-employment derived by an individual (other than a nonresident
    alien individual, except as provided by an agreement under section
    233 of the Social Security Act) during any taxable year; except
    that such term shall not include - 
        (1) in the case of the tax imposed by section 1401(a), that
      part of the net earnings from self-employment which is in excess
      of (i) an amount equal to the contribution and benefit base (as
      determined under section 230 of the Social Security Act) which is
      effective for the calendar year in which such taxable year
      begins, minus (ii) the amount of the wages paid to such
      individual during such taxable years; or
        (2) the net earnings from self-employment, if such net earnings
      for the taxable year are less than $400.

    For purposes of paragraph (1), the term "wages" (A) includes such
    remuneration paid to an employee for services included under an
    agreement entered into pursuant to the provisions of section
    3121(l) (relating to coverage of citizens of the United States who
    are employees of foreign affiliates of American employers), as
    would be wages under section 3121(a) if such services constituted
    employment under section 3121(b), and (B) includes compensation
    which is subject to the tax imposed by section 3201 or 3211,.(!1)
    An individual who is not a citizen of the United States but who is
    a resident of the Commonwealth of Puerto Rico, the Virgin Islands,
    Guam, or American Samoa shall not, for purposes of this chapter be
    considered to be a nonresident alien individual. In the case of
    church employee income, the special rules of subsection (j)(2)
    shall apply for purposes of paragraph (2).

    (c) Trade or business
      The term "trade or business", when used with reference to
    self-employment income or net earnings from self-employment, shall
    have the same meaning as when used in section 162 (relating to
    trade or business expenses), except that such term shall not
    include - 
        (1) the performance of the functions of a public office, other
      than the functions of a public office of a State or a political
      subdivision thereof with respect to fees received in any period
      in which the functions are performed in a position compensated
      solely on a fee basis and in which such functions are not covered
      under an agreement entered into by such State and the
      Commissioner of Social Security pursuant to section 218 of the
      Social Security Act;
        (2) the performance of service by an individual as an employee,
      other than - 
          (A) service described in section 3121(b)(14)(B) performed by
        an individual who has attained the age of 18,
          (B) service described in section 3121(b)(16),
          (C) service described in section 3121(b)(11), (12), or (15)
        performed in the United States (as defined in section
        3121(e)(2)) by a citizen of the United States, except service
        which constitutes "employment" under section 3121(y),
          (D) service described in paragraph (4) of this subsection,
          (E) service performed by an individual as an employee of a
        State or a political subdivision thereof in a position
        compensated solely on a fee basis with respect to fees received
        in any period in which such service is not covered under an
        agreement entered into by such State and the Commissioner of
        Social Security pursuant to section 218 of the Social Security
        Act,
          (F) service described in section 3121(b) (20), and
          (G) service described in section 3121(b)(8)(B);

        (3) the performance of service by an individual as an employee
      or employee representative as defined in section 3231;
        (4) the performance of service by a duly ordained,
      commissioned, or licensed minister of a church in the exercise of
      his ministry or by a member of a religious order in the exercise
      of duties required by such order;
        (5) the performance of service by an individual in the exercise
      of his profession as a Christian Science practitioner; or
        (6) the performance of service by an individual during the
      period for which an exemption under subsection (g) is effective
      with respect to him.

    The provisions of paragraph (4) or (5) shall not apply to service
    (other than service performed by a member of a religious order who
    has taken a vow of poverty as a member of such order) performed by
    an individual unless an exemption under subsection (e) is effective
    with respect to him.
    (d) Employee and wages
      The term "employee" and the term "wages" shall have the same
    meaning as when used in chapter 21 (sec. 3101 and following,
    relating to Federal Insurance Contributions Act).
    (e) Ministers, members of religious orders, and Christian Science
      practitioners
      (1) Exemption
        Subject to paragraph (2), any individual who is (A) a duly
      ordained, commissioned, or licensed minister of a church or a
      member of a religious order (other than a member of a religious
      order who has taken a vow of poverty as a member of such order)
      or (B) a Christian Science practitioner, upon filing an
      application (in such form and manner, and with such official, as
      may be prescribed by regulations made under this chapter)
      together with a statement that either he is conscientiously
      opposed to, or because of religious principles he is opposed to,
      the acceptance (with respect to services performed by him as such
      minister, member, or practitioner) of any public insurance which
      makes payments in the event of death, disability, old age, or
      retirement or makes payments toward the cost of, or provides
      services for, medical care (including the benefits of any
      insurance system established by the Social Security Act) and, in
      the case of an individual described in subparagraph (A), that he
      has informed the ordaining, commissioning, or licensing body of
      the church or order that he is opposed to such insurance, shall
      receive an exemption from the tax imposed by this chapter with
      respect to services performed by him as such minister, member, or
      practitioner. Notwithstanding the preceding sentence, an
      exemption may not be granted to an individual under this
      subsection if he had filed an effective waiver certificate under
      this section as it was in effect before its amendment in 1967.
      (2) Verification of application
        The Secretary may approve an application for an exemption filed
      pursuant to paragraph (1) only if the Secretary has verified that
      the individual applying for the exemption is aware of the grounds
      on which the individual may receive an exemption pursuant to this
      subsection and that the individual seeks exemption on such
      grounds. The Secretary (or the Commissioner of Social Security
      under an agreement with the Secretary) shall make such
      verification by such means as prescribed in regulations.
      (3) Time for filing application
        Any individual who desires to file an application pursuant to
      paragraph (1) must file such application on or before whichever
      of the following dates is later: (A) the due date of the return
      (including any extension thereof) for the second taxable year for
      which he has net earnings from self-employment (computed without
      regard to subsections (c)(4) and (c)(5)) of $400 or more, any
      part of which was derived from the performance of service
      described in subsection (c)(4) or (c)(5); or (B) the due date of
      the return (including any extension thereof) for his second
      taxable year ending after 1967.
      (4) Effective date of exemption
        An exemption received by an individual pursuant to this
      subsection shall be effective for the first taxable year for
      which he has net earnings from self-employment (computed without
      regard to subsections (c)(4) and (c)(5)) of $400 or more, any
      part of which was derived from the performance of service
      described in subsection (c)(4) or (c)(5), and for all succeeding
      taxable years. An exemption received pursuant to this subsection
      shall be irrevocable.
    (f) Partner's taxable year ending as the result of death
      In computing a partner's net earnings from self-employment for
    his taxable year which ends as a result of his death (but only if
    such taxable year ends within, and not with, the taxable year of
    the partnership), there shall be included so much of the deceased
    partner's distributive share of the partnership's ordinary income
    or loss for the partnership taxable year as is not attributable to
    an interest in the partnership during any period beginning on or
    after the first day of the first calendar month following the month
    in which such partner died. For purposes of this subsection - 
        (1) in determining the portion of the distributive share which
      is attributable to any period specified in the preceding
      sentence, the ordinary income or loss of the partnership shall be
      treated as having been realized or sustained ratably over the
      partnership taxable year; and
        (2) the term "deceased partner's distributive share" includes
      the share of his estate or of any other person succeeding, by
      reason of his death, to rights with respect to his partnership
      interest.
    (g) Members of certain religious faiths
      (1) Exemption
        Any individual may file an application (in such form and
      manner, and with such official, as may be prescribed by
      regulations under this chapter) for an exemption from the tax
      imposed by this chapter if he is a member of a recognized
      religious sect or division thereof and is an adherent of
      established tenets or teachings of such sect or division by
      reason of which he is conscientiously opposed to acceptance of
      the benefits of any private or public insurance which makes
      payments in the event of death, disability, old-age, or
      retirement or makes payments toward the cost of, or provides
      services for, medical care (including the benefits of any
      insurance system established by the Social Security Act). Such
      exemption may be granted only if the application contains or is
      accompanied by - 
          (A) such evidence of such individual's membership in, and
        adherence to the tenets or teachings of, the sect or division
        thereof as the Secretary may require for purposes of
        determining such individual's compliance with the preceding
        sentence, and
          (B) his waiver of all benefits and other payments under
        titles II and XVIII of the Social Security Act on the basis of
        his wages and self-employment income as well as all such
        benefits and other payments to him on the basis of the wages
        and self-employment income of any other person,

      and only if the Commissioner of Social Security finds that - 
          (C) such sect or division thereof has the established tenets
        or teachings referred to in the preceding sentence,
          (D) it is the practice, and has been for a period of time
        which he deems to be substantial, for members of such sect or
        division thereof to make provision for their dependent members
        which in his judgment is reasonable in view of their general
        level of living, and
          (E) such sect or division thereof has been in existence at
        all times since December 31, 1950.

      An exemption may not be granted to any individual if any benefit
      or other payment referred to in subparagraph (B) became payable
      (or, but for section 203 or 222(b) of the Social Security Act,
      would have become payable) at or before the time of the filing of
      such waiver.
      (2) Period for which exemption effective
        An exemption granted to any individual pursuant to this
      subsection shall apply with respect to all taxable years
      beginning after December 31, 1950, except that such exemption
      shall not apply for any taxable year - 
          (A) beginning (i) before the taxable year in which such
        individual first met the requirements of the first sentence of
        paragraph (1), or (ii) before the time as of which the
        Commissioner of Social Security finds that the sect or division
        thereof of which such individual is a member met the
        requirements of subparagraphs (C) and (D), or
          (B) ending (i) after the time such individual ceases to meet
        the requirements of the first sentence of paragraph (1), or
        (ii) after the time as of which the Commissioner of Social
        Security finds that the sect or division thereof of which he is
        a member ceases to meet the requirements of subparagraph (C) or
        (D).
      (3) Subsection to apply to certain church employees
        This subsection shall apply with respect to services which are
      described in subparagraph (B) of section 3121(b)(8) (and are not
      described in subparagraph (A) of such section).
    (h) Regular basis
      An individual shall be deemed to be self-employed on a regular
    basis in a taxable year, or to be a member of a partnership on a
    regular basis in such year, if he had net earnings from
    self-employment, as defined in the first sentence of subsection
    (a), of not less than $400 in at least two of the three consecutive
    taxable years immediately preceding such taxable year from trades
    or businesses carried on by such individual or such partnership.
    (i) Special rules for options and commodities dealers
      (1) In general
        Notwithstanding subsection (a)(3)(A), in determining the net
      earnings from self-employment of any options dealer or
      commodities dealer, there shall not be excluded any gain or loss
      (in the normal course of the taxpayer's activity of dealing in or
      trading section 1256 contracts) from section 1256 contracts or
      property related to such contracts.

        overall earnings from services performed for such company
        (without regard to whether eligibility for payment depends on
        length of service).
