Both revenue and expenditure this year are around $4 billion lower than they were projected to be back in 2011 when the Government adopted the target of returning to surplus this year. And there was always a caveat about that. It was "subject to any significant shocks". Though not on the scale of the global financial crisis or the Canterbury earthquakes, the past year has seen a significant external shock in the form of steep falls in commodity prices including dairy and oil, cutting farmers' incomes and the inflation rate respectively.
But the Government has been a bit quick to blame low inflation, which reduces nominal GDP and with it the tax base, for its likely failure to make surplus this year. The most recent Crown accounts, covering two-thirds of the current financial year, show tax revenue running a healthy 7.5 per cent ahead of the same period a year ago.
While it would have some effect this year the main impact of lower inflation on the Government's finances would be over the next couple of years, English conceded. Forecast tax revenue over the next four years has been revised down by $4.5 billion.
The low-inflation excuse also glosses over the other side of the Government's accounts. As a purchaser of goods and services, an employer, a payer of interest and a distributor of indexed transfer payment it benefits from low inflation as well. The fiscal policy the Government took to last year's election included $1 billion for new spending in this year's Budget and next year's but $2.5 billion for potential tax cuts in Budget 2017 - election year. At this stage English is "confident about the ongoing improvement in the Government's finances". This time next year, if dairy farmers face a second lousy season and inflation is not much more than 1 per cent, it may be a sterner Finance Minister we see.
