In certain rare cases you may see AVATAX listed twice on your tax item list in Netsuite. If you see two identical listings, this means you have a Tax Code and a Tax Group both named AVATAX.
Make the tax group inactive as it is not created as part of our installation and is the extra item in the list.
- Setup> Accounting> Tax Groups
- Show Inactives
- Check the Inactive box next to the correct tax group
