Section 10AA was inserted in the Income-tax Act by the Special Economic Zone Act, 2005 with effect from 10.2.2006. Through the Finance (No.2) Act, 2009, section 10AA(7) of the Income-tax Act, 1961 was amended and the words “by the undertaking” were substituted for “by the assessee” with effect from assessment year 2010-11 and subsequent assessment years. This was done as the existing formula was perceived to be discriminatory in so far as those assessees are concerned who have multiple units in both the SEZ and the domestic tariff area (DTA) vis-â-vis those assessees who were having units in only the SEZ. With a view to removing the anomaly, the provisions of sub-section (7) of section 10AA of the Income-tax Act were amended.
In order to make the amendment effective for earlier years, it is proposed, by inserting a proviso to sub-section (7), to provide that the provision of sub-section (7), as amended by Finance (No. 2) Act 2009, will apply to the assessment year 2006- 07 and subsequent assessment years.
