Expenditure-Tax Act, 1987
11. Chargeable expenditure escaping assessment
If-
(a) the 16[Assessing] Officer has
reason to believe that by reason of omission or failure on the part of the assessee
to make a return under section 8 for any assessment year or to disclose wholly
and truly all material facts necessary for his assessment for any assessment
year, chargeable expenditure for that year has escaped assessment or has been
under-assessed, or
(b) notwithstanding that there has been no
omission or failure as mentioned in clause (a) on the part of the assessee, the
16[Assessing] Officer has, in consequence of information in his
possession, reason to believe that chargeable expenditure assessable in any
assessment year has escaped assessment or has been under assessed, he may, in
cases falling under clause (a), at any time, and in cases failing under clause
(b), at any time within four years from the end of that assessment year, serve
on the assessee a notice containing all or any of the requirements which may be
included in a notice under section 8 and may proceed to assess or reassess the
chargeable expenditure, and the provisions of this Act shall, so far as may be,
apply, as if the notice were a notice issued under that section.
