Symmetry Software specializes in payroll withholding tax related software applications and services for payroll/human resources departments, software developers, and corporate intranets. At its core, Symmetry is a software development company with a high level of expertise in taxation and accounting applications with a focus towards payroll. Our team of software engineers and taxation experts provide leading edge, regulatory compliant payroll software products. Symmetry was founded by software pioneer, Tom Reahard in 1984. Tom is directly responsible for the development of 20 different accounting products on 10 different platforms including the first comprehensive PC-based payroll system.

In the late 1980's and early 1990's Symmetry developed and successfully marketed a number of "shrink-wrapped" Macintosh taxation and accounting products. As the mid 90's approached, Symmetry focused its efforts entirely towards the payroll software industry. Symmetry's Payroll Tax Table Library was first delivered in 1987 and its successor, the Symmetry Tax Engine® is the calculation engine behind millions of American's paychecks every week. The Symmetry Tax Engine® is highly regarded for its precise accuracy and timeliness.

Tom and his team created a winner in 2000 when they defied logic and successfully launched www.PayCheckCity.com. This popular free website hosts online paycheck modeling calculators and is the runaway leader in its market space, boasting the most internet traffic of any payroll oriented website.  Its Private-labeled calculators are ideal for corporate ESS portals where companies are seeking paycheck modeling solutions for employees and can fully integrate with ERP applications.  PaycheckCity also offers advertisers a targeted, payroll oriented audience.

PayCheckCity.com calculates taxes using the Symmetry Tax Engine®. Using the STE, application development teams can free themselves from the chore and expense of maintaining and updating payroll withholding tax tables,  allowing developers to focus on their application development.

The website StateW4.com is the home of Symmetry's electronic withholding forms products and services. Symmetry's process allows for completing Federal, State and Local Employee Exemption Certificates online. It virtually eliminates the paper shuffling, expense, and errors associated with traditional Form W-4 processing.

Symmetry's Payroll Point service is a mashup that combines several technologies to deliver accurate and specific details about tax withholding settings based on the addresses of where an employee lives and works

Symmetry Software is also the company behind Payroll-Taxes.com, the premier payroll research library as well as PayrollTalk.com, a forum for discussion of payroll and related issues.

Symmetry Software is based in Scottsdale, Arizona and has a development office in Bratislava, Slovakia.
