Deleting a Tax Type is a permanent action. Please confirm you're removing only tax types that you no longer need before proceeding.
Tax Types can only be deleted by Account Owners or other Admins on your account.
From your Account Settings (Link) scroll down to your Tax Types. Next, click to View the Tax Type you're looking to remove.
Then, click the pencil icon at the top right to edit the Tax Type.
Finally, click 'Delete Tax Typ'e in the bottom right.
Note that any deleted Tax Types from existing orders will appear as (Inactive) on your Tax Reports.
