Cap cut caused 25pc fall THE federal government's reduction of the concessional contribution cap to $25,000 for all savers in 2012-3 caused the average contribution per Self-Managed Super fund to drop by 25 per cent for the financial year recently ended, according to a report released yesterday. AMP's Multiport operation, which administers SMSFs, calculated that the average contribution per fund had dropped from $47,500 in the 2011-12 year to $35,200 in the year to June 30 because of the reduction in the concessional cap.
