A weaker-than-expected labour market and disappointing corporate profits are taking a toll on the Government's tax revenue and raising the risk of a higher deficit than foreshadowed even in last month's Budget Policy Statement.
The Crown accounts for the seven months to January, released yesterday, had source deductions (PAYE) 3 per cent or nearly $400 million lower than forecast in the pre-election economic and fiscal update (Prefu), while GST was 4 per cent or $350 million lower and the corporate tax take 5 per cent or $250 million lower.
Since the Prefu the Treasury has lowered its forecasts for economic growth in the short term, implying a smaller tax base and resulting in a cumulative $5.6 billion shaved off the Government's bottom line over the next five years and a correspondingly higher borrowing requirement, all else being equal.
For the current year the Budget Policy Statement revised down forecast tax revenue from the Prefu's 28.9 per cent of gross domestic product to 28.7 per cent, a drop of around $400 million.
Seven months through the year the tax revenue shortfall, relative to Prefu, is $950 million.
