What tax code and category should i use when paying my GST and PAYG tax liability?

Hi Contact36,

Thank you for reaching out on this. 

I have found this article from our community for your reference:

- Recording a GST payment (BAS Payment)

In terms of GST code, my understanding is you can use Out of Scope as GST does not need to be tracked for GST and PAYG tax liability payments, but please confirm this with your accounting professionals. 

Thank you.
