The United States has no federal GST. State and city sales tax is often about 0% to 10%. Canada uses 5% GST or 13% to 15% HST. The UK standard VAT rate is 20%, with 5% and 0% on some goods. Australia GST is 10%. Germany VAT is 19% or 7%. India GST slabs are 0%, 5%, 12%, 18% and 28%, split into CGST and SGST inside a state. The header country menu switches the name, the preset rates and the currency.

A worked check

On a 10,000 net price, 20% UK VAT adds 2,000 and the gross price is 12,000. The same 10,000 with 10% Australia GST adds 1,000. To remove 20% VAT from a 12,000 gross price, divide by 1.20. The net is 10,000 and the tax is 2,000. Subtracting 20% of 12,000 is the wrong way to remove tax.
