A company got the licence under SEZ (100% EOU) on December 2010, but it was carrying the export business from the beginning of the year. Is it possible to get tax exemption for the entire profit. i;e for the profit made during the year April 2010 to March 2011? Or the exemption will be applicable only for the profit made after the 100% EOU licence i;e from December 2010 till March 2011?
