Section 2 to Section 93 of the Amendment Act will come into effect from 01.04.2007, Section 54 of the Finance Act, 2007 which amends Section 194C of the Act specifies that the amendment in 194C will be substituted with effect from 01.06.2007. Thus, it is beyond the pale of any dispute, that the liability for deducting tax at source for payments made to individual contractors above the monetary limits arose only with effect from 01.06.2007. When the liability to make such deduction arose from 01.06.2007, it cannot be assumed that for failure to deduct such a tax at source for the previous year 2006-07, (i.e.01.04.2006 to 31.03.2007), the assessee should be put to a liability for non-deduction of such tax at source. We, therefore, hold that the asseessee was not bound to deduct tax at source for payment made to individual contractors for the assessment year in question. In the circumstances, the Tribunal went wrong in interfering with the order of the First Appellate Authority directing deletion of the disallowance made under Section 40(a)(ia) to the extent of Rs.32,18,677/- for non-payment of TDS under Section 194C of the Act. We hold that the assessee was entitled to deduct the aforesaid sum even though tax had not been deducted at source.
