Revenue Procedure 2008-50, section 4.09:
Availability of correction of § 457 plans. Submissions relating to § 457(b) eligible governmental plans will be accepted by the Service on a provisional basis outside of EPCRS through standards that are similar to EPCRS.
So, if you are a non-government entity, any EPCRS filing is futile. Since VCP is not available for the nonprofits' 457(b) plans, if you find an error like this, do you recommend that the refund be made right away anyway, plus earnings? Then document your files and change the procedures so this error can be prevented in the future? If you are audited later, could you explain that no correction option existed under EPCRS, so the plan sponsor did all they could to reasonably correct the error? Then hope the IRS shows mercy under audit cap because of your efforts to have already corrected the issue? I assume that if no correction is made, they will show little mercy when negotiating under audit cap. What do you think?
The 457 treasury regs give you a grace period for refunding excess contributions, I think it's April 15 of the year following, but you would need to confirm. If you correct after this time, then you are screwed. If the Plan retains excess contributions after this grace period deadline, then the IRS views the Plan as having converted from an eligible 457(b) plan to an ineligible 457(f) plan. Since the two plans are structured differently, you'll have immediate taxation on all amounts in the plan from the date of the error. This means that all amounts deferred thereafter will also be subject to taxation.
I would make the correction as you suggest, but wouldn't count on mercy. I would institute a new plan as part of the correction in case the IRS comes poking around to limit the amounts on which they can ding you. In our case, the plan had been in existence for decades and involved a very small excess (under $2,000) and it took almost a year to find someone within the IRS to show mercy. And their mercy was very expensive (relative to the amount of the error).
