Tax added on expense items, giving you the option to activate VAT or other tax codes by expense type (e.g. for flights and hotels but not for phone bills) and have the system calculate and propose a tax amount in your expense based on the applicable VAT etc. rate for the country in which the expense was incurred. You can typically edit both the tax rate and the amount for example to deal with cases where only a part of your hotel expense was taxable. Your system administrator can also choose in your company set-up whether to bill this tax onto customers or whether to back it out automatically and potentially replace it with a sales tax
