Tax Configuration
Configure the tax rates included in the tax group.

- Tax Rate – Displays the rate of the selected tax automatically.
- Taxable Base Rate (%) – Specifies the percentage of the transaction amount used to calculate the selected tax. The default value is 100%.
- Compounded Tax – Enable this option to calculate the selected tax on top of the transaction amount plus any previously applied taxes within the same tax group.
