Frequently Asked Questions
What's the difference between adding and removing tax?
Adding tax means you start with a base (net) price and calculate how much extra tax to include, resulting in a higher gross price. Removing tax means you start with a tax-inclusive (gross) price and work backwards to find the original net price and the tax portion. They are inverse operations.
What are common VAT rates around the world?
Common VAT/GST rates include: 0% (exempt goods), 5% (UK reduced, Canada GST), 7% (Thailand, Taiwan), 10% (Japan, Australia GST), 15% (Singapore GST, New Zealand GST), 19% (Germany), 20% (UK standard, France), 21% (Netherlands, Belgium, Ireland), 22% (Italy, Greece), and 25% (Sweden, Denmark, Norway).
Is sales tax the same as VAT?
No. Sales tax is charged only once, at the final point of sale to the consumer. VAT (Value Added Tax) is charged at each stage of production and distribution, but the end consumer effectively bears the full cost. In practice, the total tax amount paid by the consumer is often similar, but the collection mechanism differs.
