There are two challenges facing the developer attempting to compute withhoding taxes: providing a framework for the expression of complex formulas, and keeping track of changes to the formulas. For most appications, hard-coding of tax formulas is simply not a workable solution. TaxControls instead provides a simple API and tax tables which do not require compilation when changes occur. This software provides convenience in programming, but the bigger issue is maintenance of the tax tables. Because the federal, state and local tables are constantly changing, payroll programming requires a well-designed maintenance and distribution framework. Timeliness is crucial, because incorrect withholdings carry a risk of tax penalties for the employer. That's where Caliber Technology can save you time and money. We monitor the state web sites daily for changes, and provide a small, convenient table format with all the formulas. The tables even include embedded user instructions for the various state and local employee setup requirements.
