Frequently asked questions
What is the difference between adding and removing VAT/GST?
Adding tax starts from a net (tax-exclusive) price and works out the tax and the final gross price: tax = net × rate / 100, and gross = net + tax. Removing tax starts from a gross (tax-inclusive) price and works backwards to the net figure: net = gross / (1 + rate / 100), and tax = gross − net.
Are the country rate presets guaranteed to be current?
No. The presets are provided as a convenience and reflect common standard rates at the time of writing, but VAT and GST rates change and many countries also have reduced or zero rates for specific goods. Always verify the current official rate for your situation, and note that you can override the percentage in the rate field at any time.
