How can I exclude expense entries from MET?

There are two ways to exclude expense entries from being subject to the project-level Main Expense Tax (MET):

1. Set the project or phase to 0% tax and handle taxes at the item level (Activity and Expense) for items that require a tax. Leave the item level tax at 0% for those that don’t.
2. Set up a phase for the project to have 0% project-level tax, and assign those expenses to that phase.
