If a participant has excess deferral, and when calculation the gain/loss the participant incurs a loss. I thought the proper procedure was to refund the full amount back to the participant and the loss was reported on the participants taxes.
per the below, I this method might not be correct.
(2007) IRS Publication NO 525 Elective Deferrals
Report a loss on a corrective distribution of an excess deferral in the year the excess amount (reduced by the loss) is distributed to you . Include the loss as a negative amount on Form 1040, line 21 and identify it as "Loss on Excess Deferral Distribution".
Please advise if the amount should be reduce by the loss.
