Reminders Regarding Fringe Benefit Rate Functionality:

  • Effective July 1, 2021, fringe benefits is charged as a flat rate based on job/appointment type (academic, staff, postdoc, clinical fellow, etc.) and funding source (federal/state/local or other).
  • Dependent tuition will not be charged to state and local sponsors.
  • Workday and RMS will automatically apply the correct fringe rate based on HR appointment type and sponsor information.
  • These rates are already effective in RMS. Workday will be updated and the new rates will be applied on July 1, 2022.
  • Fringes will be charged only on the first $200,000 of base salary per calendar year. This is the fringe cap.
  • Once the fringe cap is reached by total base pay during a calendar year, fringes can no longer be charged to a grant even if there are remaining months of allowable salary. Note: Charging of fringe benefits will restart at the beginning of new calendar year.
  • The new rate agreement will be available on the SPA website.
  • When requested in proposals, use April 28, 2022, as the rate agreement date.
