Changes in composition of combined IR tax revenue and Customs GST collected from 2001 to 2022

This graph has four lines showing the relative shares of components of net Inland Revenue taxes and Customs GST from June 2001 to June 2022. Because these are relative shares, they all add to 100%. The graphed components are taxes on companies, taxes on individuals, GST, and duties and other revenue streams.

On 1 October 2010, the rate of GST was increased from 12.5% to 15% and the tax rates on personal incomes and companies were reduced. The company income tax rate was also reduced in the 2009 tax year. The combined effect of these changes was to increase the overall proportion of taxes collected as GST while reducing the taxes collected from individuals and companies.

Notes on the charts and accompanying tables

Measurement of Inland Revenue tax revenue is on an accrual basis. Figures are unconsolidated, including the tax of government-owned entities. Changes to accounting policies have affected the published statistics as follows:

  • Provisional tax estimation is included in company tax and other personal tax revenue in the June 2006 and subsequent years. Before June 2006, provisional tax was not estimated at the time the income was earned but was instead recognised at the due date. The accounting change had the effect of a bring-forward of some tax revenue into 2006.

  • Bad debt write-offs have been reported separately as an expense and are no longer netted against tax revenue from the June 2008 year onwards.

Source deductions includes pay as you earn (PAYE) income tax paid through employers, and ESCT (employer superannuation contributions tax).Other persons includes income tax paid directly to Inland Revenue by individuals, Māori authorities and trusts, net of refunds such as refunds of PAYE after year end return filing. It does not include tax withheld by other entities via PAYE or resident’s withholding tax (RWT) on interest and dividends.

Company tax includes income tax paid directly to Inland Revenue by companies, unit trusts, superannuation funds, PIEs, and clubs and societies, net of refunds.

GST collected by the New Zealand Customs service has been included to give more complete information on GST. Customs GST can result in refunds from Inland Revenue.
