Within the UpMail Champion’s Admin Settings there is an option to configure Default Tax Settings by going to Setup>Account Settings>General Settings>Meetings & Events Module Settings
If the checkbox is selected for your account, by default the ‘Include Taxes’ box will be checked with the default tax settings when you are editing your Events, Guestroom and Other tables.
When editing these tables within your email templates, users will have the option to uncheck the 'Include Taxes' box if they do not want the taxes to appear in these tables. They will also have the ability to change the tax amount when editing the individual tables.
