Overview
In Prokip, a Combo Tax (Tax Group) is a combination of two or more existing single tax rates applied together to products or services.
Important: Sub-taxes must already exist as single tax rates before they can be combined into a tax group.
Step 1: Create a Tax Group (Combo Tax)
Once the single taxes exist, scroll to:
Tax groups (Combination of multiple taxes)
- Click on Add to add the Tax Group
-
You can give it a name like: Combo Tax Charge
-
Select the Sub Taxes from the single taxes that already exist e.g:
-
VAT
-
Service Charge
-
Prokip will automatically calculate the combined tax rate.
