    Sec. 6201. Assessment authority

-STATUTE-
    (a) Authority of Secretary
      The Secretary is authorized and required to make the inquiries,
    determinations, and assessments of all taxes (including interest,
    additional amounts, additions to the tax, and assessable penalties)
    imposed by this title, or accruing under any former internal
    revenue law, which have not been duly paid by stamp at the time and
    in the manner provided by law. Such authority shall extend to and
    include the following:
      (1) Taxes shown on return
        The Secretary shall assess all taxes determined by the taxpayer
      or by the Secretary as to which returns or lists are made under
      this title.
      (2) Unpaid taxes payable by stamp
        (A) Omitted stamps
          Whenever any article upon which a tax is required to be paid
        by means of a stamp is sold or removed for sale or use by the
        manufacturer thereof or whenever any transaction or act upon
        which a tax is required to be paid by means of a stamp occurs
        without the use of the proper stamp, it shall be the duty of
        the Secretary, upon such information as he can obtain, to
        estimate the amount of tax which has been omitted to be paid
        and to make assessment therefor upon the person or persons the
        Secretary determines to be liable for such tax.
        (B) Check or money order not duly paid
          In any case in which a check or money order received under
        authority of section 6311 as payment for stamps is not duly
        paid, the unpaid amount may be immediately assessed as if it
        were a tax imposed by this title, due at the time of such
        receipt, from the person who tendered such check or money
        order.
      (3) Erroneous income tax prepayment credits
        If on any return or claim for refund of income taxes under
      subtitle A there is an overstatement of the credit for income tax
      withheld at the source, or of the amount paid as estimated income
      tax, the amount so overstated which is allowed against the tax
      shown on the return or which is allowed as a credit or refund may
      be assessed by the Secretary in the same manner as in the case of
      a mathematical or clerical error appearing upon the return,
      except that the provisions of section 6213(b)(2) (relating to
      abatement of mathematical or clerical error assessments) shall
      not apply with regard to any assessment under this paragraph.
    (b) Amount not to be assessed
      (1) Estimated income tax
        No unpaid amount of estimated income tax required to be paid
      under section 6654 or 6655 shall be assessed.
      (2) Federal unemployment tax
        No unpaid amount of Federal unemployment tax for any calendar
      quarter or other period of a calendar year, computed as provided
      in section 6157, shall be assessed.
    (c) Compensation of child
      Any income tax under chapter 1 assessed against a child, to the
    extent attributable to amounts includible in the gross income of
    the child, and not of the parent, solely by reason of section
    73(a), shall, if not paid by the child, for all purposes be
    considered as having also been properly assessed against the
    parent.
    (d) Required reasonable verification of information returns
      In any court proceeding, if a taxpayer asserts a reasonable
    dispute with respect to any item of income reported on an
    information return filed with the Secretary under subpart B or C of
    part III of subchapter A of chapter 61 by a third party and the
    taxpayer has fully cooperated with the Secretary (including
    providing, within a reasonable period of time, access to and
    inspection of all witnesses, information, and documents within the
    control of the taxpayer as reasonably requested by the Secretary),
    the Secretary shall have the burden of producing reasonable and
    probative information concerning such deficiency in addition to
    such information return.
    (e) Deficiency proceedings
          For special rules applicable to deficiencies of income,
        estate, gift, and certain excise taxes, see subchapter B.

    Sec. 6211. Definition of a deficiency

-STATUTE-
    (a) In general
      For purposes of this title in the case of income, estate, and
    gift taxes imposed by subtitles A and B and excise taxes imposed by
    chapters 41, 42, 43, and 44 the term "deficiency" means the amount
    by which the tax imposed by subtitle A or B, or chapter 41, 42, 43,
    or 44 exceeds the excess of - 
        (1) the sum of
          (A) the amount shown as the tax by the taxpayer upon his
        return, if a return was made by the taxpayer and an amount was
        shown as the tax by the taxpayer thereon, plus
          (B) the amounts previously assessed (or collected without
        assessment) as a deficiency, over - 

        (2) the amount of rebates, as defined in subsection (b)(2),
      made.
    (b) Rules for application of subsection (a)
      For purposes of this section - 
        (1) The tax imposed by subtitle A and the tax shown on the
      return shall both be determined without regard to payments on
      account of estimated tax, without regard to the credit under
      section 31, without regard to the credit under section 33, and
      without regard to any credits resulting from the collection of
      amounts assessed under section 6851 or 6852 (relating to
      termination assessments).
        (2) The term "rebate" means so much of an abatement, credit,
      refund, or other repayment, as was made on the ground that the
      tax imposed by subtitle A or B or chapter 41, 42, 43, or 44 was
      less than the excess of the amount specified in subsection (a)(1)
      over the rebates previously made.
        (3) The computation by the Secretary, pursuant to section 6014,
      of the tax imposed by chapter 1 shall be considered as having
      been made by the taxpayer and the tax so computed considered as
      shown by the taxpayer upon his return.
        (4) For purposes of subsection (a) - 
          (A) any excess of the sum of the credits allowable under
        sections 24(d), 32, and 34 over the tax imposed by subtitle A
        (determined without regard to such credits), and
          (B) any excess of the sum of such credits as shown by the
        taxpayer on his return over the amount shown as the tax by the
        taxpayer on such return (determined without regard to such
        credits),

      shall be taken into account as negative amounts of tax.
    (c) Coordination with subchapters C and D
      In determining the amount of any deficiency for purposes of this
    subchapter, adjustments to partnership items shall be made only as
    provided in subchapters C and D.

    Sec. 6212. Notice of deficiency

-STATUTE-
    (a) In general
      If the Secretary determines that there is a deficiency in respect
    of any tax imposed by subtitles A or B or chapter 41, 42, 43, or 44
    he is authorized to send notice of such deficiency to the taxpayer
    by certified mail or registered mail. Such notice shall include a

    office of the taxpayer advocate and the location and phone number
    of the appropriate office.
    (b) Address for notice of deficiency
      (1) Income and gift taxes and certain excise taxes
        In the absence of notice to the Secretary under section 6903 of
      the existence of a fiduciary relationship, notice of a deficiency
      in respect of a tax imposed by subtitle A, chapter 12, chapter
      41, chapter 42, chapter 43, or chapter 44 if mailed to the
      taxpayer at his last known address, shall be sufficient for
      purposes of subtitle A, chapter 12, chapter 41, chapter 42,
      chapter 43, chapter 44, and this chapter even if such taxpayer is
      deceased, or is under a legal disability, or, in the case of a
      corporation, has terminated its existence.
      (2) Joint income tax return
        In the case of a joint income tax return filed by husband and
      wife, such notice of deficiency may be a single joint notice,
      except that if the Secretary has been notified by either spouse
      that separate residences have been established, then, in lieu of
      the single joint notice, a duplicate original of the joint notice
      shall be sent by certified mail or registered mail to each spouse
      at his last known address.
      (3) Estate tax
        In the absence of notice to the Secretary under section 6903 of

      deficiency as provided in subsection (a), and the taxpayer files
      a petition with the Tax Court within the time prescribed in

-HEAD-
    Sec. 6213. Restrictions applicable to deficiencies; petition to Tax
      Court

-STATUTE-
    (a) Time for filing petition and restriction on assessment
      Within 90 days, or 150 days if the notice is addressed to a
    person outside the United States, after the notice of deficiency
    authorized in section 6212 is mailed (not counting Saturday,
    Sunday, or a legal holiday in the District of Columbia as the last
    day), the taxpayer may file a petition with the Tax Court for a
    redetermination of the deficiency. Except as otherwise provided in
    section 6851, 6852, or 6861 no assessment of a deficiency in
    respect of any tax imposed by subtitle A, or B, chapter 41, 42, 43,
    or 44 and no levy or proceeding in court for its collection shall
    be made, begun, or prosecuted until such notice has been mailed to
    the taxpayer, nor until the expiration of such 90-day or 150-day
    period, as the case may be, nor, if a petition has been filed with
    the Tax Court, until the decision of the Tax Court has become
    final. Notwithstanding the provisions of section 7421(a), the
    making of such assessment or the beginning of such proceeding or
    levy during the time such prohibition is in force may be enjoined
    by a proceeding in the proper court, including the Tax Court, and a
    refund may be ordered by such court of any amount collected within
    the period during which the Secretary is prohibited from collecting
    by levy or through a proceeding in court under the provisions of
    this subsection. The Tax Court shall have no jurisdiction to enjoin
    any action or proceeding or order any refund under this subsection
    unless a timely petition for a redetermination of the deficiency
    has been filed and then only in respect of the deficiency that is
    the subject of such petition. Any petition filed with the Tax Court
    on or before the last date specified for filing such petition by
    the Secretary in the notice of deficiency shall be treated as
    timely filed.
    (b) Exceptions to restrictions on assessment
      (1) Assessments arising out of mathematical or clerical errors
        If the taxpayer is notified that, on account of a mathematical
      or clerical error appearing on the return, an amount of tax in
      excess of that shown on the return is due, and that an assessment
      of the tax has been or will be made on the basis of what would
      have been the correct amount of tax but for the mathematical or
      clerical error, such notice shall not be considered as a notice
      of deficiency for the purposes of subsection (a) (prohibiting
      assessment and collection until notice of the deficiency has been
      mailed), or of section 6212(c)(1) (restricting further deficiency
      letters), or of section 6512(a) (prohibiting credits or refunds
      after petition to the Tax Court), and the taxpayer shall have no
      right to file a petition with the Tax Court based on such notice,
      nor shall such assessment or collection be prohibited by the
      provisions of subsection (a) of this section. Each notice under
      this paragraph shall set forth the error alleged and an
      explanation thereof.
      (2) Abatement of assessment of mathematical or clerical errors
        (A) Request for abatement
          Notwithstanding section 6404(b), a taxpayer may file with the
        Secretary within 60 days after notice is sent under paragraph
        (1) a request for an abatement of any assessment specified in
        such notice, and upon receipt of such request, the Secretary
        shall abate the assessment. Any reassessment of the tax with
        respect to which an abatement is made under this subparagraph
        shall be subject to the deficiency procedures prescribed by
        this subchapter.
        (B) Stay of collection
          In the case of any assessment referred to in paragraph (1),
        notwithstanding paragraph (1), no levy or proceeding in court
        for the collection of such assessment shall be made, begun, or
        prosecuted during the period in which such assessment may be
        abated under this paragraph.
      (3) Assessments arising out of tentative carryback or refund
        adjustments
        If the Secretary determines that the amount applied, credited,
      or refunded under section 6411 is in excess of the overassessment
      attributable to the carryback or the amount described in section
      1341(b)(1) with respect to which such amount was applied,
      credited, or refunded, he may assess without regard to the
      provisions of paragraph (2) the amount of the excess as a
      deficiency as if it were due to a mathematical or clerical error
      appearing on the return.
      (4) Assessment of amount paid
        Any amount paid as a tax or in respect of a tax may be assessed
      upon the receipt of such payment notwithstanding the provisions
      of subsection (a). In any case where such amount is paid after
      the mailing of a notice of deficiency under section 6212, such
      payment shall not deprive the Tax Court of jurisdiction over such
      deficiency determined under section 6211 without regard to such
      assessment.
    (c) Failure to file petition
      If the taxpayer does not file a petition with the Tax Court
    within the time prescribed in subsection (a), the deficiency,
    notice of which has been mailed to the taxpayer, shall be assessed,
    and shall be paid upon notice and demand from the Secretary.
    (d) Waiver of restrictions
      The taxpayer shall at any time (whether or not a notice of
    deficiency has been issued) have the right, by a signed notice in
    writing filed with the Secretary, to waive the restrictions
    provided in subsection (a) on the assessment and collection of the
    whole or any part of the deficiency.
    (e) Suspension of filing period for certain excise taxes
      The running of the time prescribed by subsection (a) for filing a
    petition in the Tax Court with respect to the taxes imposed by
    section 4941 (relating to taxes on self-dealing), 4942 (relating to
    taxes on failure to distribute income), 4943 (relating to taxes on
    excess business holdings), 4944 (relating to investments which
    jeopardize charitable purpose), 4945 (relating to taxes on taxable
    expenditures), 4951 (relating to taxes on self-dealing), or 4952
    (relating to taxes on taxable expenditures), 4955 (relating to
    taxes on political expenditures), 4958 (relating to private excess
    benefit), 4971 (relating to excise taxes on failure to meet minimum
    funding standard), 4975 (relating to excise taxes on prohibited
    transactions) shall be suspended for any period during which the
    Secretary has extended the time allowed for making correction under
    section 4963(e).
    (f) Coordination with title 11
      (1) Suspension of running of period for filing petition in title
        11 cases
        In any case under title 11 of the United States Code, the
      running of the time prescribed by subsection (a) for filing a
      petition in the Tax Court with respect to any deficiency shall be
      suspended for the period during which the debtor is prohibited by
      reason of such case from filing a petition in the Tax Court with
      respect to such deficiency, and for 60 days thereafter.
      (2) Certain action not taken into account
        For purposes of the second and third sentences of subsection
      (a), the filing of a proof of claim or request for payment (or
      the taking of any other action) in a case under title 11 of the
      United States Code shall not be treated as action prohibited by
      such second sentence.

        The term "return" includes any return, statement, schedule, or
