and gains of an eligible business to which the provisions of sub-section (1) apply
shall, for the purposes of determining the quantum of deduction under that sub-sec -
tion for the tax year immediately succeeding the initial tax year or any subsequent

the assessee during the initial tax year and to every subsequent tax year up to and
including the tax year for which the determination is to be made.
(8) The deduction under sub-section (1) from profits and gains derived from an
eligible business shall not be admissible unless the accounts of the eligible busi -

accountant, before the specified date referred to in section 63 and the assessee
furnishes by that date the report of such audit in the prescribed form duly signed
and verified by such accountant.

( i )   for the purposes of the eligible business are transferred to any other
business carried on by the assessee; or
( ii )   for the purposes of any other business carried on by the assessee are
transferred to the eligible business,
and, in either case, the consideration, if any, for such transfer as recorded in
the accounts of the eligible business does not correspond to the market value of
such goods or services as on the date of the transfer, then, for the purposes of the
deduction under this section, the profits and gains of such eligible business shall
be computed as if the transfer, in either case, had been made at the market value
of such goods or services as on that date.
(10) For the purposes of sub-section (9), where, in the opinion of the Assessing Offi -

or services, means—

section 164.
(12) Where any amount of profits and gains of an undertaking or of an enterprise
in the case of an assessee is claimed and allowed under this section for any tax year,
deduction to the extent of such profits and gains shall not be allowed under any
other provisions of Part C of this Chapter and shall in no case exceed the profits
and gains of such eligible business of undertaking or enterprise, as the case may be.

is so arranged that the business transacted between them produces to the assessee

eligible business for the purposes of the deduction under this section, take the
amount of profits as may be reasonably deemed to have been derived therefrom.
(14) Where the arrangement as mentioned in sub-section (13) involves a specified
