Treasury exposes mining tax flaws as Martin Parkinson blames Labor's concessions

TREASURY secretary Martin Parkinson has admitted the design of the mining tax is responsible for its failure to generate revenue, not the falling commodity prices, higher currency and state royalties blamed by the government.
In explosive testimony to the Senate economics committee yesterday, Dr Parkinson said Treasury had compiled its budget forecasts in ignorance of the real cost of concessions agreed to by Wayne Swan and Resources Minister Martin Ferguson when they renegotiated the tax in private with the chief executives of BHP Billiton, Rio Tinto and Xstrata in mid-2010.
"We've adjusted those estimates for the things that we can see that have changed in the interim. What we haven't done is adjust the estimates for things that we can't see," he said.
Reporting a $3 billion loss as it wrote down the value of assets, Rio yesterday confirmed that it had paid no minerals resource rent tax on its massive West Australian iron ore operations or its east-coast coalmines.
Dr Parkinson said that when Treasury lowered its forecast for first-year revenue from the MRRT from the $3bn predicted in last May's budget to $2bn in the October update, it had taken into account falling commodity prices, the high value of the Australian dollar and increases in state government royalties. "We can see the commodity prices . . . and we can get very quick estimates of movements in volume," he said. "The second thing we can see in real time is the exchange rate; and the third thing we can see in real time is state royalty rates."
Dr Parkinson said the two big variables it did not take into account - and which resulted in the tax raising only $126 million in its first six months - were the value that the mining companies put on their assets (the starting base for the tax) and the share of the profits that is attributable to downstream operations not covered by the mining tax.
He said Treasury was hoping for the assistance of the mining industry in working out where it had gone wrong. "We now have to find out: is there something we missed," he said. He said the mining companies had given Treasury estimates of the valuations they would put on their mines when the tax was negotiated in July 2010, but had not updated Treasury about revisions they might have made.
"When . . . the mining industry talked with us there was no legal obligation on them to have actually settled on the starting base," he
said. "They actually had the opportunity to go back and think about what their starting base should be. They gave us their best estimate, as we understand it, their best estimate at the time, but they clearly had until the point they are legally obligated for the tax the opportunity to rethink that."
Asked by opposition assistant Treasury spokesman Mathias Cormann whether Treasury was "flying blind" when it compiled the forecasts, Dr Parkinson replied: "We can't see changes that may have been made."
The government has faced a barrage of criticism in parliament this week over the failure of the tax to meet its revenue forecasts.
Julia Gillard faces pressure from her own backbench, as well as the independents and the Greens, to make changes to the tax to fix the revenue shortfall. The government has indicated it has no plans to change the design of the tax but it will continue negotiations with the states aimed at taking away the states' ability to raise royalties at the expense of the commonwealth.
Dr Parkinson's testimony highlights the concessions given by Mr Swan and Mr Ferguson, and signed off by the new Prime Minister, when they renegotiated the tax one week after the overthrow of Kevin Rudd in mid-2010.
Where the original resource super-profits tax proposed by the Rudd government had required mining companies to value their projects at their written-down book value, the new tax allowed them to use the market value of their assets at March 2010 and then claim depreciation.
An assessment by investment bank UBS compared the book value of BHP's Queensland Coal mines of $3.7bn with its market value of almost $18bn.
With a higher value, the companies can make bigger tax deductions for depreciation.
The revised tax also applies only to profits derived from mining, not from processing, transporting and shipping minerals.
Dr Parkinson suggested the mining companies may be attributing more profit to these downstream activities than Treasury expected.
Senator Cormann said Dr Parkinson's testimony showed Mr Swan had been "reckless" in agreeing to the concessions. He had "signed up to a major concession as part of his failed mining tax deal, formally committed the commonwealth to it and even got the Prime Minister to sign it when he had no idea what the cost of that significant concession was".
A spokeswoman for Mr Swan said there was nothing unusual in Dr Parkinson's admission that Treasury did not know what values the mining companies would be using for their assets in calculating the tax. "Treasury does not have access to the full financial details of individual taxpayers, but bases its forecasts on the best available data," she said.
Broking analysts and mining companies suspected, from the beginning, that companies' ability to put a market value on their assets would have a big impact.
A week after the tax was agreed, the then Coalition industry spokesman Ian Macfarlane suggested no tax would be paid: "The companies involved in the negotiations will be paying no more tax than they are now. We're starting to think the whole thing is a sham."
Association of Mining and Exploration Companies chief executive Simon Bennison last night told a Senate estimates hearing that Treasury understood the concessions that had been offered to the big miners. "They went in with their eyes wide open, knowing the design of the tax would provide for big tax deductions from their starting base," he said.
Announcing his company's annual results, new Rio chief executive Sam Walsh revealed that his company - the nation's biggest and most profitable iron ore producer - has paid no MRRT since the tax was introduced last July. He would not say whether Rio expected to pay the tax this year.
Mr Walsh said calls to rejig the tax could affect future investment in the mining industry. "It's very important in our industry . . . that we have certainty," he said.
Lance Cunningham, national director of tax at BDO, told The Australian it was well known in the industry how the MRRT and its depreciation scheme would work.
"The method they have used has given them the advantage of being able to claim a greater amount from their starting value than perhaps the government had envisaged," he said.
