So, a bit about us

Arizona Tax & Business PLLC was established in 2004 as SS2 Enterprises, LLC. Principals, Joan D Schnell & Kimberly J Schnell, a mother/daughter partnership, started the company in order to serve the Avra Valley & Marana communities & their large extended family, while still working full-time on the East side of Tucson.

In 2011, Joan & Kim struck out on their own leaving the corporate world behind. The name changed in 2012 to Arizona Tax & Business PLLC, fondly referred to as ATB In a complete role reversal, their former manager, Carol Swango, began working part-time for Joan & Kim in 2013. Between the three of them, they have over 125 years of tax season experience. In addition, their staff is all family & extended family, making ATB truly a family-run business.
