To prevent a tax from displaying in the list of available taxes, you can either make it inactive or simply delete it.

1. Making a tax inactive

To make a tax inactive in Nutcache, simply display the tax file and set the tax status to "Inactive". This way, you can always set the tax status back to "Active", should you wish to use this tax again in the future.

2. Deleting a tax

In order to delete permanently a tax in Nutcache, you need to select the "Delete" action from the list of available taxes. Please note that you cannot delete a tax once it has been used in a transaction.
