Understanding GST in Australia and New Zealand

Goods and Services Tax is a consumption tax applied to most goods and services. While the principle is the same in both countries, the rates are the key difference.

Australia’s GST Rate: 10%

The Australian Goods and Services Tax is set at a flat rate of 10%. It’s a broad-based tax that applies to most items, with some notable exemptions like basic food, some medical services, and education. For businesses, accurately calculating this 10% is essential for lodging Business Activity Statements (BAS). For more detailed information, you can visit the Australian Taxation Office (ATO) website.

New Zealand’s GST Rate: 15%

New Zealand has a higher standard GST rate of 15%. Like Australia, it applies to most goods and services, and registered businesses are responsible for collecting it on behalf of the government. Understanding this 15% rate is vital for anyone doing business in or with New Zealand. For official guidelines, please refer to the New Zealand Inland Revenue (IRD) website.
