When you create a new tax rate, it is NOT automatically applied to any existing Products. If you'd like to tax all your Products at a location, or just some of your products it's easy to do!

Just click "Apply Tax to Products" at the right of the Tax Rates page:

You can use filters and searches to add the products you would like to assign that tax to or you can choose to add all products.

Once all products that you want to be assigned to that tax rate are on the right-hand side click Save.
