Keeping track of hours worked is time consuming enough. Much less having to calculate the gross payroll, compute the withholdings, administer garnishments and track all the taxes.
States have their own withholdings, unemployment insurance and workers compensation requirements.
These monies are considered trust monies, as they are being deposited for your employees benefits. Any delays in depositing them can result in severe penalties. This includes preparing paystubs, journal entries and required tax forms. Due to the various local taxes, these quotes are given on a case by case basis. Preparing payroll in Texas is easier than in Pennsylvania as Texas doesn't have any State or Local income taxes to compute.
