Tax Outturn Data

Page updated 13 Feb 2018

Tables of monthly tax revenue and receipts from collecting departments

Tax data are sometimes difficult to interpret as economic indicators, but tax outturns are among the earliest data available about the state of the economy. The Government has decided that it is important that this information about the economy should be available to market analysts, and the general public, as soon as possible.

Monthly tax outturn data are published here usually just over six weeks after the end of the month, shortly after they are reported to Ministers.

Outturns for December 2017

Total unconsolidated tax revenue for the six months ended December 2017 was $567 million (1.4%) above the 2017 Half-Year Economic and Fiscal Update (2017 HYEFU) forecast and $1.7 billion (4.4%) greater than last year. GST and source deductions were above forecast while corporate tax was below forecast.

Total unconsolidated tax receipts for the six months ended December 2017 were $644 million (1.7%) above the 2017 HYEFU forecast and $2.1 billion (5.7%) higher than last year. GST and source deductions were above forecast. For further details, refer to the Financial Statements of the Government of New Zealand for the Six Months to 31 December 2017.


The figures reported in the spreadsheets below are on an unconsolidated basis, adding to total tax, and differ from the figures reported in the monthly financial statements of Government. The monthly financial statements are prepared on a consolidated basis, meaning they eliminate tax transactions between Departments, State-owned enterprises and Crown entities. The eliminations are included in Section III in the Monthly History spreadsheet for comparison with the figures in the financial statements of the Government.


The tax outturn data tables are available in MS Excel format only. Using MS Excel Files 

Next Release of Tax Outturn Data

The Treasury publishes tax outturns in conjunction with the release of the monthly Financial Statements of the Government of New Zealand. Sometimes there are delays in data collection due to audits, holidays, or changes to processes. If the release date should change, a message will appear on this page and on the Treasury main page. The upcoming release dates are listed on the Treasury's Calendar of Upcoming Releases. The standard time for each release will be 10am.

Glossary of Tax Terms

The Glossary of Tax Terms explains some of the common names and terms used in tax-related reports, including the difference between tax receipts and tax revenue. Where relevant, notes explaining if the tax type no longer exists and when it was abolished, its relative importance in the overall tax take etc are included.

Tax Revenue Outturns

Tax revenue, which measures tax due in a given time period, entails estimation. Some tax types use taxpayers' own estimates from their tax returns. These are subject to revisions when new returns are filed, application of revenue recognition rules when assessments and payments do not reconcile, etc. Other tax types require some estimation from the tax-collecting entity because returns for the current period are usually unavailable at the time of reporting. While several checks are done, such as sampling and individually reviewing exceptionally large estimates, the nature of revenue means it is more difficult to measure than receipts. Tax revenue figures are audited independently at 30 June each year and adjustments made if necessary. For these reasons, the monthly track of many tax types may be more erratic for revenue than receipts.

Notes on Historical Data

The "Monthly history" spreadsheet includes monthly tax receipts and revenue data from July 1990 and July 1993 respectively. Each worksheet tab contains up to four sections. The first section displays monthly cash receipts/accrual revenue by tax type. We have omitted some very minor taxes.

The second section consists of aggregates: individuals, corporates (net company, foreign-source dividends, non-resident withholding), net GST.

The third section shows the eliminations that, when removed, give Core Crown Tax and Fully Consolidated Tax respectively.

The fourth section shows tax write-offs by tax type. From June 2007, tax revenues have been reported gross of tax write-offs, whereas previously they were reported net of tax write-offs. Tax write-offs are now included separately as an expense item in the financial statements. To get a series consistent with the figures prior to June 2007, users of the data may like to subtract tax write-offs from the corresponding tax revenue line above.
