Most countries have a form of GST/VAT/Sales tax that varies by type of purchase. It’ll be nice to be able to specify the GST/VAT/Sales tax rate per item under expenses, since some countries like New Zealand have a 15% GST, which can significantly plans.

Currently, the workaround is to include the GST/VAT/Sales tax in the total expense number, but this makes it difficult to adjust and scale expenses easily and for the GST/VAT/Sales tax to be accurately reflected.
