Frequently Asked Questions
What is the difference between GST and VAT?
GST (Goods and Services Tax) and VAT (Value Added Tax) are essentially the same concept — a consumption tax on goods and services. The term varies by country: GST is used in Australia, Canada, India, while VAT is used in the EU, UK, and many other countries.
How do I calculate the price before tax?
Divide the tax-inclusive price by (1 + tax rate). For example, if the price is $110 with 10% GST: $110 ÷ 1.10 = $100 is the pre-tax price.
