457 Plan Company contribution deduction code

Legacy Contributor

Our 457 Plan is defined as a Contribution Limits type plan. An employee group limits the plan's eligible participants. I need to find a way to track the one time company match so it shows up on the W2 as part of their contribution for the year. I defined a company deduction for the company's contribution.The company and employee deduction codes stops the contribution at the maximum limit. The problem I have discovered is that any employee can have the company deduction code. If you have a keying error an employee who is not in the plan will have the deduction code on their paycheck. You do not receive an error message that the employee is not enrolled in the plan. Is there another way to set up the company contribution to limit the deduction code to only those enrolled in the plan.
