FAQ
Frequently asked questions
How do I remove 20% VAT from a price?
Divide by 1.2, don't multiply by 0.8. £120 including VAT is £100 before VAT — multiplying by 0.8 would wrongly give £96.
What are Canada's sales tax rates?
GST is 5%. HST is 13% in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador and PEI. BC and Manitoba add 7% PST, Saskatchewan 6%, and Quebec 9.975% QST.
Why isn't there a US state list?
US sales tax varies by state, county and city, so the right rate depends on the exact address. Enter the combined rate shown on your receipt.
