( b) within three years after that date, purchased any other land or building or
any right in any other land or building or constructed any other building

year in which the transfer took place, it shall be dealt with as follows:—
( i) if the capital gains exceeds the cost of new asset, such excess shall be

from the transfer of the new asset within three years of its purchase or
construction, the cost shall be nil; or
( ii) if the capital gains is equal to or less than the cost of new asset, no capital
gains shall be charged under section 67 and for computing capital gains
from the transfer of the new asset within three years of its purchase or
construction, the cost shall be reduced by the amount of the capital gains.
(2) If the capital gains referred to in sub-section (1) is not utilised by the assessee to
purchase the new asset before filing the return of income under section 263, then—

( b) such deposit shall be made before the filing of the return not later than
the due date applicable in the case of the assessee for filing the return
of income under section 263(1); and
( c) the proof of deposit shall be submitted along with such return.
(3) For the purposes of sub-section (1), the amount already utilised for purchas-
ing or constructing the new asset together with the deposited amount under sub-
section (2), shall be deemed to be the cost of the new asset.
(4) If the amount deposited under sub-section (2) is not fully utilised for the purchase
or construction of the new asset within the period specified in sub-section (1), then,—
( a) the unutilised amount shall be charged under section 67 as the income
of the tax year in which three years from the date of the transfer of the
original asset expires; and
( b) the assessee shall be entitled to withdraw such unutilised amount in
accordance with the scheme referred to in sub-section (2).
