There are two ways to edit & review your taxes on an estimate:
Option 1 - "Edit Taxes"
To change or update taxes on items in one or more workareas within the same estimate simultaneously, use the "Edit Taxes" option from within the workarea/service.
A new window will open that will allow you to change items within your estimate, and apply those changes to one or more workareas/services.
Option 2 - Workareas/Services + Pricing
Go to the "Workareas + Pricing" section for a standard estimate, or "Services + Pricing" for a Service estimate.
Select the workarea or service that requires changes to taxes to open the details for that service/workarea.
Select the "Edit Taxes" tab. This will allow you to select/change purchase and sales taxes and edit Warranty and shipping percentages.
