How GST and VAT work
GST and VAT are consumption taxes charged as a percentage of the selling price. The rate is set by each country's government and varies widely — from 5% in Canada to 27% in Hungary. Businesses collect the tax on behalf of the government and pass it on. Consumers ultimately pay it embedded in the final price.
Adding tax to a price (tax-exclusive)
Example: A product costs $200 before 10% GST. Tax = $20. Total = $220.
Removing tax from an inclusive price
Example: A receipt shows £96 including 20% VAT. Pre-tax = 96 ÷ 1.20 = £80. VAT = £16.
