In New Zealand Goods and Services Tax is a value-added tax which is paid across all goods and services that are taxation liable. The same GST calculation applies for both consumer GST and business based GST calculations. The main difference is nearly all consumer prices include GST within the price whereas most business based purchases are advertised without GST.

If you would like to see the results for the previous GST rate in New Zealand which was 12.50% before October 1st, 2010 simply change the existing GST rate of 15% to 12.5% on the left-hand menu.

Alternatively, if you would like to see the rate that would apply for Australian GST calculations enter 10.00%.
