You can find these within the 'Account Settings' menu under the 'Integration' tab. There is the 'Publishing tax data to purchases' setting that you can set to:
1.'Allow Receipt Bank to decide'
Selecting this option will always send the sales tax from Receipt Bank to Xero using the “Tax amount” used for the individual receipts. Use it to prevent Xero overwriting the tax amount so that the tax shown in Receipt Bank will always be the same as that in Xero.
2.'Allow Receipt Bank to decide with exceptions'
To use the tax shown on an item when publishing apart from in 3 exceptional cases:
- When the tax on an item is 0.00,
- When the tax amount field on an item is blank or empty,
- When the default tax rate for a category in Xero is Zero Rated
3.‘Allow Xero to calculate’
Selecting this option will ignore the “Tax amount” that’s in Receipt Bank and recalculate sales taxes in Xero using the default tax rate for the account/category selected.
Use it to disable your ‘Supplier’ rules, ignore the tax amount shown in Receipt Bank and calculate the tax on an item based on the ‘total amount’ and the default tax rate of the category.
You can also enable ‘Show tax list’ to provide a dropdown box when viewing an item to change the item’s tax rate from the amount extracted by Receipt Bank to a specific rate.
