Shadow treasurer Chris Bowen says a Labor government would review all tax rates when fiscal circumstances allow.
But in the interim it would not scrap the two per cent deficit levy on high income earners that is due to end next year.
"When fiscal circumstances allow we would review all the tax rates ... but we believe with all the budget pressure, the triple-A rating under pressure, the need to get back to budget balance, taking the deficit levy off when the deficit has tripled is not justified," he told Sky News on Sunday.
