Frequently Asked Questions
GST (Goods and Services Tax) and VAT (Value Added Tax) are functionally the same — both are consumption taxes on goods and services. The name varies by country: Australia, Canada, India, and New Zealand use GST, while the UK and EU use VAT.
Multiply the net price by (1 + tax rate). For example, to add 10% GST to $100: $100 × 1.10 = $110. The GST amount is $10.
Divide the gross price by (1 + tax rate) to get the net price, then subtract. For 20% VAT on £120: £120 ÷ 1.20 = £100 net, so the VAT is £20.
Use the rate for your country or the country where the sale occurs. Common rates: Australia 10%, UK 20%, Canada 5% (federal GST), EU 19-27%, New Zealand 15%. Some goods may have reduced or zero rates.
