When setting up GST in QuickBooks Online (QBO), the system will automatically calculates taxes by the time you add them to a transaction.
The calculation will be based on the following:
- Your customer's tax exempt status
- Where you sell and where you ship
- Your service or product's tax category
To learn more about the setup process, consider checking out this article: Set up and use GST in QuickBooks Online.
For more information about filing your GST return in QBO, refer to this article: File your GST return and record tax payment in QuickBooks Online.
