The infrastructure for software and payroll platforms powering the paychecks of over 64M+ workers.
Our Mission
To reach every American paycheck with accurate withholding and accelerate compliance with a technology-first approach to payroll taxes. In other words, to help you get “the right taxes the first time®.”
Our Promise
With 40 years of expertise in tax compliance, Symmetry Software will deliver efficient and dependable solutions as well as experienced and friendly customer service.
Our Vision
Create payroll technology to solve tax compliance issues and build applications across the entirety of the payroll process. Powered by deep tax compliance relationships enabled by technology.
Modern technology that
developers love + compliance teams trust.
Symmetry Software founder, Tom Reahard, wrote his first payroll system for the Apple II in 1979 while a Ph.D. student at Arizona State University after learning from a ComputerLand associate that “people wanted to do payroll on the computer.” A nights and weekends self-taught coder, he started Symmetry Software in 1984. Symmetry is now the second oldest software company in the greater valley of Phoenix, Arizona. Over time, Symmetry created additional unique payroll tax technologies that today provide an infrastructure relied upon by hundreds of thousands of growing businesses and millions of employees.
Over the last 40 years, we’ve had the privilege of calculating paychecks for millions of working Americans. In addition, we’ve helped America’s largest companies determine the right payroll taxes for their employees.
In July of 2021, Symmetry Software became part of Gusto. We believe that the paycheck is the most fundamental building block for creating a better life and are excited to have Gusto behind us as we further our efforts to ensure payroll tax compliance across the entire payroll industry. Our focus is to help clients accelerate compliance with a technology-first approach to payroll taxes.

If you don’t have a Payroll Goddess blinky badge or Payroll Titan pin, catch us at our next trade show to pick up your own!
Buttons
We couldn’t do any of this without the trusty calculator; therefore, we decided to make a calculator our Symmetry Software Mascot and name him Buttons. Buttons’ role in the company has increased throughout the years; for example, he recently became the face of our chatbot for symmetry.com. We have many more plans for Buttons, so stay tuned.
