What is GST and How Does It Work?
Goods and Services Tax (GST) is a broad-based consumption tax levied on most goods and services sold for domestic consumption. It is collected at each stage of the supply chain but ultimately borne by the end consumer. Different countries call it by different names: GST in Australia, Canada, India, and New Zealand; VAT (Value Added Tax) in the UK, Europe, and UAE; HST (Harmonized Sales Tax) in certain Canadian provinces. Despite the different names, the calculation method is the same.
