Budget repair levy won't be extended

The federal government will not extend a levy on top earners even though its budget is being hit by revenue writedowns.

Assistant Treasurer Josh Frydenberg says the government will stick to its promise last year that the two per cent deficit levy on people earning more than $180,000 annually will only last for three years.

"There's no plans to expand or to extend that temporary budget deficit levy," he told Sky News on Monday.
