Frequently Asked Questions
What is the difference between Sales Tax, VAT, and GST?
Sales tax is collected once at retail sale. Value Added Tax (VAT) and Goods and Services Tax (GST) are multi-stage consumption taxes collected throughout the supply chain.
How do I extract VAT/GST from a tax-inclusive total?
Select "Reverse / Remove Tax", enter your gross receipt amount and tax rate. The calculator divides by (1 + rate/100) to isolate pre-tax price and tax paid.
