Event managers have the ability to choose to display prices on the event to either include tax or exclude tax. This setting must be chosen before registrations have been taken, and affects prices for tickets and sessions.
Include or exclude tax
To choose to include tax in displayed prices:
Go to Setup > Financial > Settings
Under Financial Settings, select to display prices either as “Include Tax” or “Exclude Tax”
Click “Save” to keep your changes.
Note: The options may be greyed out if registrations have already been taken, or if there are in-progress registrations.
