A2X has the ability to split out 'No Tax' sales transactions meaning that any orders or orders including products that don't include tax can be separated out from all other sales that do include tax.
If you are using the Amazon VAT calculation service your sales VAT will come through to A2X already separated out from the sales figures within your settlements. This means that if you are completing your VAT returns or reporting from within your accounting system the separated tax amounts will need to be wrapped back into the applicable income and expense accounts so that the your VAT rates can be applied in your tax rate mapping section of the Accounts and Taxes page in A2X. Tax line wrapping is explained in more detail HERE.
Using the 'No Tax' grouping feature in A2X means that the Sales lines you apply your tax rates to in the A2X Accounts and Taxes mapping will only include the sales amounts that actually incurred tax. With the sales amounts being split simply between sales that incurred tax and sales that didn't incur tax, you are able to apply the applicable tax rate mapping in A2X so that your accounting system can accurately calculate your VAT liability.
