What is GST?
GST (Goods and Services Tax) is a broad-based consumption tax levied on the supply of goods and services at each stage of the production and distribution chain. It is designed to be paid by the final consumer, similar to VAT (Value Added Tax).
While GST and VAT share the same principle — taxing value added at each stage — the key difference is in how they are named and administered. Countries like Australia, New Zealand, Canada, India, and Singapore use the term "GST," while most European countries call it "VAT." The underlying mechanism is essentially the same.
Country-specific GST rates:
- Australia: 10% GST on most goods and services
- New Zealand: 15% GST (one of the broadest bases with very few exemptions)
- Canada: 5% federal GST (some provinces combine with provincial tax for a Harmonized Sales Tax)
- India: Multi-tier structure with rates of 0%, 5%, 12%, 18%, and 28%
- Singapore: 9% GST (as of 2024)
Formula
Adding GST (net to gross):
Gross = Net + GST Amount
Removing GST (gross to net):
GST Amount = Gross − Net

Frequently Asked Questions
What is GST?
GST (Goods and Services Tax) is a value-added consumption tax applied at each stage of the supply chain. The end consumer ultimately bears the full cost of GST, which businesses collect and remit to the government on their behalf.
How is GST different from VAT?
GST and VAT are essentially the same type of tax — both are consumption taxes collected at each stage of production. The main difference is naming: countries like Australia and Canada use "GST," while European nations use "VAT." Some countries like India use GST with a multi-rate structure, while others apply a single flat rate.
What are GST rates in Australia?
Australia applies a flat 10% GST on most goods and services. Some items are GST-free, including basic food, certain medical services, education, and childcare. There is no reduced or concessionary GST rate in Australia — it is a single 10% rate.
