Wealth    escaping assessment.
17.    [(1) If the Assessing Officer [has reason to believe] that the net wealth    chargeable to tax in respect of which any person is assessable under this Act    has escaped assessment for any assessment year (whether by reason of under-    assessment or assessment at too low a rate or otherwise), he may, subject to    the other provisions of this section and section 17A, serve on such person a    notice requiring him to furnish within such period, [***] as may be specified    in the notice, a return in the prescribed form and verified in the prescribed    manner setting forth the net wealth in respect of which such person is    assessable as on the valuation date mentioned in the notice, along with such    other particulars as may be required by the notice, and may proceed to assess    or reassess such net wealth and also any other net wealth chargeable to tax in    respect of which such person is assessable, which has escaped assessment and    which comes to his notice subsequently in the course of the proceedings under    this section for the assessment year concerned (hereafter in this section    referred to as the relevant assessment year), and the provisions of this Act    shall, so far as may be, apply as if the return were a return required to be    furnished under section 14 :
Provided    that where an assessment under sub-section (3) of section 16 or this section    has been made for the relevant assessment year, no action shall be taken under    this section after the expiry of four years from the end of the relevant    assessment year, unless any net wealth chargeable to tax has escaped    assessment for such assessment year by reason of the failure on the part of    the assessee to make a return under section 14 or section 15 or in response to    a notice issued under sub-section (4) of section 16 or this section or to    disclose fully and truly all material facts necessary for his assessment for    that assessment year :
[Provided    further that the Assessing Officer shall, before issuing any notice under    this sub-section, record his reasons for doing so:]
[Provided    also that nothing contained in the first proviso shall apply in a case    where any net wealth in relation to any asset (including financial interest in    any entity) located outside India chargeable to tax, has escaped assessment    for any assessment year:]
[Provided    also that the Assessing Officer may assess or reassess such net wealth,    other than the net wealth which is the subject matter of any appeal, reference    or revision, which is chargeable to tax and has escaped assessment.]
Explanation.—Production    before the Assessing Officer of account books or other evidence from which    material evidence could with due diligence have been discovered by the    Assessing Officer will not necessarily amount to disclosure within the meaning    of the foregoing proviso.
(1A)    No notice under sub-section (1) shall be issued for the relevant assessment    year,—
[(a)     if four years have elapsed from the end of the relevant assessment year, unless the case falls under clause (b) [or clause    (c)];
(b) if four years, but not more than six years, have elapsed from the end of the relevant assessment year unless the net wealth chargeable to tax which has escaped assessment amounts to or is likely to amount to rupees ten lakhs or more for that    year;]
[(c) if four years, but not more than sixteen years, have elapsed from the end of the relevant assessment year unless the net wealth in relation to any asset (including financial interest in any entity) located outside India, chargeable to tax, has escaped assessment for any assessment year.]
[Explanation    1].—For the purposes of sub-section (1) and sub-section (1A), the    following shall also be deemed to be cases where net wealth chargeable to tax    has escaped assessment, namely :—
(a)     where no return of net wealth has been furnished by the assessee although his net wealth or the net wealth of any other person in respect of which he is assessable under this Act on the valuation date exceeded the maximum amount which is not chargeable to wealth-tax    ;
(b)     where a return of net wealth has been furnished by the assessee but no assessment has been made and it is noticed by the Assessing Officer that the assessee has understated the net wealth or has claimed excessive exemption or deduction in the    return;
[(c)     where a person is found to have any asset (including financial interest in any entity) located outside India.]
[Explanation    2.—For the removal of doubts, it is hereby clarified that the provisions    of this section, as amended by the Finance Act, 2012, shall also be applicable    for any assessment year beginning on or before the 1st day of April, 2012.]
(1B)    (a) In a case where an assessment under sub-section (3) of section 16    or sub-section (1) of this section has been made for the relevant assessment    year, no notice shall be issued under sub-section (1) [by an Assessing    Officer, who is below the rank of Assistant Commissioner [or Deputy    Commissioner], unless the [Joint] Commissioner is satisfied, on the reasons    recorded by such Assessing Officer, that it is a fit case for the issue of    such notice] :
Provided    that, after the expiry of four years from the end of the relevant assessment    year, no such notice shall be issued unless the Chief Commissioner or    Commissioner is satisfied, on the reasons recorded by the Assessing Officer    aforesaid, that it is a fit case for the issue of such notice.
(b)    In a case other than a case falling under clause (a), no notice shall    be issued under sub-section (1) by an Assessing Officer, who is below the rank    of [Joint] Commissioner, after the expiry of four years from the end of the    relevant assessment year, unless the [Joint] Commissioner is satisfied, on the    reasons recorded by such Assessing Officer, that it is a fit case for the    issue of such notice.]
[Explanation.—For    the removal of doubts, it is hereby declared that the Joint Commissioner, the    Commissioner or the Chief Commissioner, as the case may be, being satisfied on    the reasons recorded by the Assessing Officer about fitness of a case for the    issue of notice, need not issue such notice himself.]
[(2)    Nothing contained in this section limiting the time within which any    proceeding for assessment or reassessment may be commenced, shall apply to an    assessment or reassessment to be made on such person in consequence of or to    give effect to any finding or direction contained in an order under section    23, 24, 25, 27 or 29 [or by a Court in any proceedings under any other law] :
Provided    that the provisions of this sub-section shall not apply in any case where any    such assessment or reassessment relates to an assessment year in respect of    which an assessment or reassessment could not have been made at the time the    order which was the subject-matter of the appeal, reference or revision, as    the case may be, was made by reason of any provision limiting the time within    which any action for assessment or reassessment may be taken.]
