I recently discovered how to use VAT with Categories. I've set up a few VAT Categories and associated them with several expense categories. Tests so far indicate I've configured VAT and Categories correctly. There's one problem that I can't resolve. In Ontario Gas taxes amount to approximately 29%. HST (Harmonized Sales Tax) in the amount of 13% is also charged on each gasoline purchase. I've set up VAT Categories for both HST and Gas but only one VAT may be selected on the Tax tab of the "Fuel" category. I know I can add the two taxes together into one VAT Category however doing so doesn't allow the these taxes to be tracked independently. The ability to track both tax types would be advantageous.

I agree that assigning multiple vat to a category would be useful. Moreover VAT is a bit restrictive. For example on my income, I may want to track different components besides VAT, for example: Gross income VAT 5% Pension fund 2 %
