Why can't I find tax code 0N020000 when trying to map my items?

Overview

I am trying to use a non taxable tax code for item mapping and suddenly 0N020000 is no where to be found.

Tax code 0N020000 has been expired since 3/1/15

Please use tax code NT for non taxable if you would simply like to have a tax code that never taxes.
