One of the major claims raised by the respondents in their returns was deduction under Section 80-IB(10). Such returns were taken up for scrutiny and the assessing officer passed orders of assessment under Section 143(3) granting deduction under Section 80IB(10) as claimed by the respondents herein. However, after a period of four years, the assessing officer sought to reopen the assessments on the ground that the respondents company are not eligible to claim deduction under Section 80-IB(10) in the light of the explanation inserted below section 80-IB(10) of the Act by Finance Act, 2 of 2009 with retrospective effect from 1-42000 whereunder, it was stated that deduction under section 80IB(10) of the Act shall not be admissible to a contractor in respect of works contract awarded by any person. On receipt of the notices for re-assessment, the respondents have submitted their objections, but they were rejected.
