The Az. Dept. of Revenue is changing the way businesses complete their sales tax returns beginning January 1st, 2015. While the process will remain the same, with both form and online filing options, the classifications will change. There are now numerous “business class codes”. Business will need to select the correct code for their business type. For instance, Restaurants will no longer report sales under the code CE000 under retail sales but will now use code CE011 Restaurants & Bars. For a complete listing of the new codes see the updated Transaction Privilege Tax Codes listing in the Finance Documents Section. You can also follow the link below to the AzDOR site but not all business class codes are included on their site as of this posting.
