By configuring the correct tax type within ReRum to match with Xero, this will allow the correct tax to be recognised when transfering invoices and purchases onto Xero.
1 - To access Tax Codes you go to Admin -> Finance -> Tax Codes.
2 - You will then open up all the tax codes created and within your system. Within each of these codes they will include a Xero Tax Type. Select the Tax Type you wish to view.
3 - As you can see here there is a field called 'Xero Tax Type'. This can be configured for each code. Edit the tax code.
4 - Xero Tax Types can vary for different tax codes and countries as they are all different.
The U.K's standard are
INPUT2 - 20% (VAT on Expenses)
OUTPUT2 - 20% (VAT on Income)
These are the basic Tax Types that can be used, however with the link below, you can choose different tax types and use tax types from other countries.
5 - This is an example of how it would look. Once this is done click update.
