Three months into the Government's financial year its tax revenue was running 6.1 per cent higher than in the same period last year, while core Crown expenses were up 1.1 per cent.
The Crown accounts for the three months to September 30 include a 6.2 per cent increase in source deductions (PAYE) compared with the September 2012 quarter and a 7.3 per cent increase in corporate tax.
The $200 million increase in expenditure is entirely explained by a 3.5 per cent increase in social security and welfare, which includes superannuation, reflecting both indexation and an increase in recipient numbers.
Other spending lines were modestly over or under their levels of last year.
Compared with forecasts in last May's Budget, tax revenue in the September quarter was 1.1 per cent higher, while core Crown expenses were 1.4 per cent lower.
