The way it is explained to us, sales tax in Arizona is really Transaction Privilege Tax or called TPT. For all contractors the upcoming changes in the 2015 AZ TPT law will affect all contractors in one way or another.
As of 1/1/15, we at Norman S. Wright are required to charge sales tax on all purchases that do not have a Form 5009L or a 2015 TPT license.
This change will affect jobs that are already in progresss. Any materials you pick up after 1/1/15 will be taxed unless you have either a 2015 AZ Form 5000 or a Form 5009L from your general contractor.
