Most growth in net Inland Revenue GST from 2001 to 2023 has been in customers with GST turnover exceeding $1 million. Net Inland Revenue GST in this band grew by 0.7% for the year to 31 March 2023 (5% in the previous year) and is 422% higher than the year to 31 March 2001. The growth in GST collected from taxpayers with turnover of more than $1 million was higher than the growth in the number of customers in this band (up 165%), indicating that the growth is driven by both an increase in the number of taxpayers and increasing sales, as well as the GST rate increase from October 2011.
