Frequently Asked Questions
What is the difference between VAT and sales tax?
VAT is charged at each stage of production, while sales tax is added only at the final point of sale to the consumer.
How do I add or remove VAT from a price?
To add, multiply the net price by (1 + the VAT rate); to remove, divide the gross price by the same factor.
What does "VAT-inclusive" mean?
An inclusive price already contains the tax, so the tool can back out the net amount and the tax portion for you.
