A. No, assets cannot be transferred from the 403(b) plan to the 401(k) plan. If participants have a distributable event, however, the 403(b) assets could be rolled over to the 401(k) plan (or to an IRA). If the 403(b) plan is funded with individual accounts, any movement of money would need to be authorized by each individual participant, because the employer would not have the authority to arbitrarily move those monies. Since an ineligible transfer has taken place, the employer should review Revenue Procedure 2013-12 for guidance on the correction methodology.
