I am showing Anniston as calculating tax in Alabama even though I have it turned off in Nexus.
The city of Anniston Alabama changed from compulsory to non compulsory in October 2014.
This means that before October 2014 it was administered by the state and was rightfully calculating tax.
They are now self administered and should be on your list of cities to turn on or off in nexus for Alabama.
If nexus is turned off for Anniston Alabama you can and should still see tax for calculations there before October 2014.
For transactions AFTER October 1 2014 you should see Anniston as 0 taxable if nexus is turned off there.
