The documents reveal previously unpublished details of the breadth and scope of tax reform considered by the then-Prime Minister and Treasurer in the early months of the new government,some of which - such as increasing the GST and curbing negative gearing - had been broadly canvassed publicly at the time.
But other proposals,such as cutting the top marginal tax rate to 40 per cent and the bottom rate to 17 per cent,removing the tax-free threshold and replacing it with an earned income tax credit and a 25 per cent tax discount for all savings were not canvassed publicly.
Five separate options to wind back negative gearing tax concessions were canvassed by Treasury with Mr Turnbull,Mr Morrison and the cabinet,as was reducing the capital gains tax discount to 25 per cent,while four major options for tax reform were floated.
While governments regularly receive policy proposals from the public service that they do not adopt,leading economists Chris Richardson and Danielle Wood and Australian Chamber of Commerce and Industry boss Andrew McKellar said the leaked documents highlighted — on the eve of the federal budget and an election — the lack of tax reform ambition from both the Coalition and Labor.
Three of the four major tax reform options involved changes to the GST to raise the rate to 15 per cent and broaden the base,cutting company tax to 25 per cent,reducing the capital gains tax discount and in the most ambitious proposal — which had an estimated size of $82 billion and would have increased GDP by 2.5 per cent — abolishing state stamp duties on conveyancing and insurance taxes,while doubling council rates.
The less ambitious two options did not touch state taxes,still raised and broadened the GST and the estimated size of these “tax mix switches” was $55billion and $45 billion respectively.
In February 2016,Labor announced changes to limit negative gearing to new properties only and a cut to the capital gains tax discount from 50 per cent to 25 per cent,two of the options privately canvassed by Treasury in its work for the government.
