If you are incorporated as an S Corporation, the IRS requires you to run a payroll. In addition, if you pay someone to do work for your business you become responsible for deducting payroll taxes based on wages earned. These taxes are then required to be paid to IRS and State agencies. Payroll reports are required to be filed quarterly and annually. Payroll processing is time consuming and often confusing. By outsourcing your payroll, you will have more free time and be less worried about whether you are in compliance with ever changing rules associated with payroll.
