Crisis: Slugging households to fix budget 'unsustainable'
May 27 2017
Financial Review
Australia faces a budget crisis because the Turnbull government is asking households to bear an unsustainable tax burden for budget repair, says Bob Gregory, emeritus professor of economics at ANU.
A budget crisis looms because the Turnbull government is asking ordinary households and workers to do the heavy lifting of budget repair by paying higher income taxes as company taxes and wages sag, top budget experts say.
The 2017 budget is built on heroic assumptions about company taxes and wages growth returning to pre-global financial crisis levels, and the burden will instead fall on wage and salary earners who will have to pay higher effective income tax rates via bracket creep to close the gap.
The squeeze on households as company taxes are being cut and indirect taxes flatline is unsustainable and will bring about a budget crisis, yet the major political parties are silent on the issue, Bob Gregory, emeritus professor of economics at Australian National University, will say on Tuesday.
"My view is that it will not be possible to increase income taxes to levels implied by forecast company tax revenue," Professor Gregory, a former Reserve Bank of Australia board member, will tell the Melbourne Economic Forum.
"Of course the crisis will be greater and arrive sooner if Treasury has again over forecast company tax revenue," he will say.
The government raised the threshold for the 37 per cent second top income tax rate last year to ease bracket creep – the process by which average tax rates increase as wages increase with constant thresholds – last year, while Labor wants to increase the top rate to 49.5 per cent.
This will bring the political bogeys of increasing the GST and imposing a mining tax back on to the agenda, Professor Gregory will say, adding to the political stresses around budget planning.
Squeeze on households
Households are already trimming their spending as wages stagnate and mortgage borrowings increase to record levels to pay for boom-level house prices.
John Fraser, Secretary of the Treasury, was forced to defend the government's wages growth forecasts during Budget Estimates at Parliament House in Canberra.
With wages grinding below 2 per cent a year, a record low in data dating to the late 1990s, the government is under pressure over budget projections that the measure will surge towards 4 per cent in coming years.
Mr Fraser said his department's wages outlook was its "best forecast and projection" taking into account the "far greater optimism at the global level" which he said was now being picked up more widely after Treasury noted it 18 months ago.
"It is a palpably more optimistic world that we're facing," he said, referring to buoyant financial markets and economic data.
"We haven't uninvented the business cycle," he said, adding that meant there would be improvements in wages as the labour market tightens.
But John Daley and Danielle Wood, chief executive and fellow of the Grattan Institute, write in The Australian Financial Review on Tuesday that Treasury has consistently forecast about $30 billion too much revenue each year for seven years because its rose-tinted model over-estimates nominal GDP and wages growth.
Dr Daley and Ms Wood will tell the forum that governments need to be more realistic because over optimistic revenue and growth forecasts are leading them to deny the need for budget repair and rely too much on bracket creep.
Treacherous politics
The treacherous budget politics of hitting households hardest will make it harder to win public approval for tax cuts for large companies, which have been blocked by the Senate, especially as many are foreign multinationals, Professor Gregory will say.
"It seems difficult to argue, as is implicit in current policy, that Australians should increase personal income tax rates to historically high levels in order to cut company taxes that will largely accrue to foreigners."
Professor Gregory will say the GFC marked a dramatic turning point in the Australian tax mix. Company taxes had increased as a share of GDP since the mid-1980s until that point, personal income taxes had fallen, and indirect (sales) taxes had flatlined.
From the GFC until 2020, by sharp contrast, company taxes fall, indirect taxes remain unchanged or fall, despite the introduction of the GST in 2000, and personal income tax revenues increase after the Howard era tax cuts take effect.

This is inconsistent with political rhetoric, which focuses on cutting company tax rates and forecasting increases in company tax revenue that don't occur, while ruling out GST increases.
