Form 8955-SSA has no minimum filing threshold. Filing is based on participant status. If a separated participant holds an unpaid deferred vested benefit, they generally need to be reported, regardless of the benefit amount.
A common filing issue with Form 8955-SSA is omitting a separated participant who still holds a deferred vested benefit, or not updating previously reported participant information when their status changes. Both can trigger IRS penalties.
The IRS imposes a $10 per participant per day penalty for failure to file or for omitting required participants, up to $50,000. Failing to report plan status changes carries a separate $10 per day penalty, up to $10,000.
File an amended Form 8955-SSA by checking the "amended registration statement" box in Part I. The amended filing must be complete, meaning the entire form needs to be resubmitted, not just the section with the error. Use Entry Code B in Part III for corrected participant information.
