Do I have to include Fringe benefit payments on my certified payroll reports?

Yes, if you are paying your fringe benefits in cash, then you must show the actual base rate of pay, PLUS the Fringe Benefit rate per hour, that is paid directly to the employee. 

For federal Davis-Bacon projects, however, if you pay all required fringe benefits defined by the wage decision to an approved plan (such as an ERISA Trust), then you only need to show the base rate of pay for Straight Time and Overtime.

For California prevailing wage work you are required to report gross contributions to fringe benefit plans on the certified payroll report. This is to be done for each plan for which the employee is enrolled.  This amount is reflected in Box 8 of the A-1-131 form.
