Whether you're a software developer starting from scratch, or a payroll service provider planning on improving your existing payroll solution, the Symmetry Tax Engine (STE) is the most powerful tax engine on the market.
A tax engine is a powerful calculator that calculates every payroll tax imaginable, including: Federal, FICA, state withholdings for all 50 states, Puerto Rico, US Territories, select local taxes, and various other payroll-related withholdings. Our tax engine accounts for employer taxes, benefits taxation, and multi-state processing. Even nexus and reciprocity are considered. And because we know these taxes change frequently, we support you with timely and accurate updates to the engine.
But the best part? Knowing your payroll taxes will be right, the first time.
Quick calculations, monthly updates - the STE helps you make sure your payroll is accurate, every time.
The STE utilizes geocoding technology to normalize addresses, and also takes nexus, reciprocity, state, local, and federal taxes into consideration.
Consistently updated to always calculate the right taxes, the first time. The STE just works - calculating even the most complicated tax scenarios.
