How to ignore tax for unincorporated area in atlanta city

Hi,

We have a vendor who falls in an unincorporated area(no local city tax). I know that in ebusiness tax, we can create a jurisdiction at the city level and you can check/uncheck as a "inner jurisdiction" which will calculate/not calculate the city tax based on that setting.

However the point is ,vendor address is falling in Atlanta city  in dekalb  County (xxxxx) and he says that zip code is in unincorporated area, but the city is still Atlanta city. At the city level(Atlanta), it is definitely not a unincorporated area.

As the ebiz tax does not allow us to define jurisdictions at the zip code level (lowest is the city level) we are not sure, how we can avoid city tax for him.
