"Goods and services tax (GST) is a broad-based tax of 10% on most goods, services and other items sold or consumed in Australia."
The "most" in this statement is the most misleading word there is.
There are so many variations, exemptions and interpretations.
- Most insurances
- Phone bills that still include the white/yellow pages listing
- Imported goods
- Digital goods
- Fees and charges
- Australian v non Australian companies
- Second hand goods
- Trading of going concerns
- Business to Business v Business to Consumer
- Precious metal trading
The best and only way is having a copy of the source document available to confirm GST treatment and or know the relevant part of the tax act for the required treatment (yes/no or part GST)
This knowledge is another difference between a data entry Bookkeeper and a great Bookkeeper (and why only registered BAS agents are allowed to provide fee for service where GST is coded)
