Wealth tax amendment narrows transitional date ranges for section 17A provisos, restricting their window of applicability. Amendment of section 17A of the Wealth tax Act (effective 1 July 2012) substitutes provisos to limit their temporal scope: sub section (1) is confined to assessment years commencing on or after 1 April 2004 but before 1 April 2010; sub sections (2) and (3) are confined to dates after 1 April 2005 but before 1 April 2011, thereby narrowing the transitional applicability of those provisos.
