Specifying GST amounts (AU) - eg. airfares

Hi - Airfares have complex taxation. They do have GST, but they also have a number of other taxes and charges, so the GST is not 10% of the total fare.

Is there a way of inputting the GST component from the airline’s tax invoice manually rather than having it automatically calculated?

You need to split the amount into GST and GST-free portions. So let’s say if airfare is $1,000 and $100 is GST-free, then you need to split the amount so only $900 is subject to GST 10% and remaining $100 is marked with GST-free tax code.

Good workaround! A bit of backward engineering is required to work out the GST-component, but I’ll have a go. Thanks for prompt reply!
