NP 457(b) Plan and Excess Deferrals

[Guest Golden Girl]

I am hoping for guidance.

If an employee has excess deferrals for 2013, what are the mechanics for getting those funds refunded?

The excess deferrral arose from the participant deferring 15,000 and the company putting in a 40% vested contribution of 10,000. That gets deferrals to 15,000 + 4,000 or 19,000 with excess deferals of 1,500.

Is the 1,500 returned to the employer and they pay out on a Form W-2?

If this is discovered after the end of 2013 - does an amended 2013 W-2s need to be done?

Thanks much
