In an interview earlier this week, Wayne Swan refused to comment on speculation concerning the outcome and response to the Henry Tax Review.
Australian capital gains and income tax could all be affected by the proposals outlined in the review, which is finalising its recommendations following a public consultation that attracted over 1,000 submissions.
Responding to a question about the prospect of new taxes for Australians, Mr Swan said: "It is too early for people to speculate about what may be or not be in the Henry Review.
"We will receive that review soon. We will deal with it early next year. I guess there will be an enormous amount of speculation - much of it inaccurate - between now and then, but I don't intend to respond to the sort of speculation."
The full review is expected to be published by the end of the year and will recommend a tax, interactions and transfer system to the government that authors believe will help the country to meet the demographic, social and economic challenges of the future.
