Wrap Document-125 Plan with different PYE than other benefits?

[Guest Carolyn Barnard]

I understand that a "wrap" plan can be advantageous to an employer who's been filing several 5500s every year. However, I have a plan sponsor who wants to create one plan for their self-funded health and dental, life, LTD and flex benefits. The only problem is that the health, dental, life and LTD are 10/31 plan year ends, and the 125 plan has a 12/31 plan year end. They have not been filing on the Health Reimbursement Account as it did not meet the participant threshold. It will however, for the 1/1/04 - 12/31/04 plan year. Is it allowable to keep the 125 plan on a 12/31 basis and yet report on it as a 10/31 if it is included in the wrap plan? Which document overrides, or does the 125 plan just have to have the same plan year end under the wrap plan provisions?
