As a previous Paychex employee, we had to learn & understand how to manually calculate checks and quarterly returns. Its very disturbing when I come across business owners who pay their employees cash. When calculating a check to receive NET PAY, you have to take into consideration excess and taxable wages because that will play a role in their federal withholding along with their allowances. Thiswill also play a major role with SUI/ quarterly returns. Take the time and get operations running properly!
