GST turnover is calculated from GST returns as the sum of gross sales in the year ended 31 March.
For a two-monthly filer, this would mean the sum of gross sales on six successive GST returns, with the last return being for the period ending 31 March.
The GST tables only include GST collected or refunded by Inland Revenue. GST collected on imports by the New Zealand Custom Service is not included.

Customers not registered for GST or PAYE and not belonging to large enterprises (LE) and non-profit organisations (NPO).

Notes:

1. This includes individual customers receiving income from business (eg, rental property, shares) but not registered for GST or PAYE.
2. Where there are overlaps between LE, NPO, SME and individuals, entities are allocated to the group with higher priority. The priorities are:
   1. large enterprises (LE)
   2. non-profit orgs (NPO)
   3. small and medium enterprises (SME)
   4. individuals.

Taxable income for individuals is income on which their personal income tax is assessed for the March year.
For people with IR3 tax returns or Personal tax summaries, this is income from all taxable sources less allowable deductions and losses. People with negative income because of losses are recorded as having nil taxable income in the tables. For people who are non-filers, taxable income is assumed to be their total PAYE gross earnings in the year ended 31 March. PAYE gross earnings can include income from employment, and also taxable welfare benefits, New Zealand Superannuation, earnings-related ACC, student allowances, and paid parental leave.
