The amendment clarifies the tax treatment of income arising from investments made before 1st April 2017, that it is excluded from the applicability of Chapter XI provisions. While Anti-Abuse provisions will apply to all arrangements, regardless of when they were entered into, if the tax benefit arises on or after 1st April 2017, an exception is carved out for income derived from the transfer of investments made prior to 1st April 2017, which remains outside the scope of these anti-abuse provisions.
