Questions people ask
How do I add GST?
Multiply the net price by 1 plus the rate. At 10%, multiply by 1.1.
How do I remove GST from a price?
Divide the gross price by 1 plus the rate, not take 10% off. At 10%, divide by 1.1. Taking 10% off gives the wrong answer because the tax was added to the smaller net price.
What rate applies in my country?
UK VAT is 20% (5% and 0% for some goods), Ireland 23% (13.5%, 9% and 0%), UAE 5%, Australia GST 10%, New Zealand GST 15%, and Canada 5% GST plus provincial tax, up to 15% HST. Pick your country above to see its rates.
