Is it permissible to have EACA for only one type of compensation, such as bonus?

[jkharvey]

Employer wants to automatically withhold deferral from a quarterly bonus only. Any restrictions on this?

[DPL]

Does anyone know the answer to the question yet?  An EACA would really help one client if it could be uniformly applied to "plan compensation" which consists of bonuses only.  Client needs the 6 month period for ADP refunds because there are always 415 issues with the ESOP, and the test is run after the 415 issues are addressed.

without even thinking about other ramifications, would such a plan even pass the comp test?
