Participant Compensation used in Deduction Limits for Combo Plans

[jbrindisi77]

I was told an EA conference speaker mentioned that when applying the 31% deduction limit for a combo plan, that you can only use the participant's compensation if they are receiving an employer contribution in either plan. For example, I have a plan that is not Top-Heavy and they are not giving the HCEs an employer contribution in either plan but they are able to contribute 401(k). He is saying I would not be able to include their compensation when calculating the deduction limits. I wanted to use the 6% limit on the profit sharing contribution. The HCEs are not excluded they are just in their own class and get 0%. Would I not be able to use their compensation in calculating the maximum deductible contribution?

Maybe their class should receive an allocation of $1.00 each?
