"Greg recently had the opportunity to meet with The Hon. Scott Morrison to discuss negative gearing," the email notes. "As a result of that meeting, Greg agreed to provide a report to the Treasurer – he asked Brian Haratsis to undertake a study on the impact of the proposed negative gearing changes."

It also asks for feedback as "the Treasurer is keen to get the report next week". Entitled "Short Memory: Negative Gearing and Capital Gains Tax: Foundations of the New Australian Housing Model," the attached draft report is also presented with an alternative title: "Shortened Memory".

It claims Labor's policy would remove 205,000 dwellings from the rental housing stock over a decade, adding to housing stress. Asked why removing dwellings from the rental stock would add to housing stress when the dwellings would still be available for use, Mr Haratsis said the phrase was meant to refer to low-income rental dwellings.

Mr Haratsis explained the apparent contradiction by saying the market was bifurcated and that different parts of it would react differently. Mr Paramor confirmed to Fairfax Media he had recently met with Mr Morrison over the negative gearing issue but denied he had been asked for the research by the Treasurer. Illustration: Ron Tandberg

"It [negative gearing] was one of the things we discussed," he said, but he "didn't know" why the leaked email from a member of his staff said the Treasurer was keen to get the draft report this week. Mr Morrison's office said the Treasurer met with "many people from the community and the real estate industry who are raising concerns about Labor's negative gearing proposal". I am writing this as we go, and there are a number of references that you are looking at that won't be there in the final The Treasurer's office denied he had asked for a report to be prepared or that he or his office had received copies. The report also says Australian governments would need to stump up an extra $3.3 billion per year for social housing and rent assistance should Labor's policy became law, more than the $3.2 billion per year it would raise.

The total economic cost of Labor's policy would be $5 billion per year, a reference Mr Haratsis said has since been removed from the document after acknowledging that it was arrived at by adding up payments without subtracting receipts. "I am writing this as we go, and there are a number of references that you are looking at that won't be there in the final," he said. "I want to go back and recalculate the numbers." Prepared in haste with what appears to have been a speech recognition program, the draft at one point refers to Labor's promise to "grandfather" the entitlements of existing investors as a promise to create "ground furthered" properties. The leaking of the report potentially blunts another avenue of attack on Labor's plan to restrict negative gearing to new properties only and halve the capital gains tax discount to 25 per cent, which has been the subject of a fierce government scare campaign. Mr Haratsis insisted it was his decision to initiate the report after his meeting with Mr Paramor, that he would fund the work himself and that it was planned for release next week - at which point "I could maybe give it to the Treasurer".

The report critiques organisations such as the Grattan Institute, which engages in "Robin Hood economics" and chooses to "ostracise high income individuals" instead of focusing on tax efficiency. Follow James Massola and Peter Martin on Facebook Follow us on Twitter
