Simon Crean to fight plan for superannuation tax changes as internal rift deepens SIMON Crean has deepened the rift within Labor over looming budget changes to the superannuation regime, declaring he would oppose any move by the government to tax earnings on super accounts. Launching an attack on Labor's inability to frame serious policy debate, the senior party figure would not comment on whether he would cross the floor to vote against any changes. But he called on the government to explicitly rule out changes that retrospectively taxed earnings generated by super accounts, saying it was "tantamount to taxing people's retirement surpluses to fund our surplus."
