For over 25 years, Symmetry has provided the tax calculation engine for millions of paychecks calculated every payday. For software developers, the Symmetry Tax Engine® is a logical component of your payroll application. Virtually every community in America has employees whose paycheck withholding calculations are computed by a Symmetry Tax Engine®. Why not go with the leader? The tax team managing PaycheckCity.com can also keep your tax tables up-to-date.

Symmetry Software supports customers with timely and accurate updates and supporting documentation.
