It is preferable that you use the contribution reports which we send you on a monthly basis. The reason for this is that the names of the employees appear in our computer system in the same order as they appear on the contribution reports. This makes entering the data into the computer much easier and less prone to error. If you are going to submit contributions on a worksheet that you have created, we request that you make sure the employees are listed in alphabetical order with social security numbers. The hours and wages should be displayed next to each name. When submitting a self-generated report be sure to attached our report to the back or your report.
