What is Form 8955-SSA?
Last updated October 2, 2026
Form 8955-SSA reports separated participants who still have vested benefits in the plan, so the Social Security Administration can later remind them. It's filed with the IRS on the Form 5500 schedule, and chronic non-filing is a common cleanup item in plan audits.
When employees leave with vested balances they don't immediately take, the plan reports them on Form 8955-SSA. Decades later, when those individuals claim Social Security, the SSA notifies them that a retirement plan may still owe them money — the mechanism behind those "you may have a benefit" letters.
Filing follows the Form 5500 calendar (including extensions) but goes to the IRS separately. Participants are added in the year after separation (with some timing flexibility) and removed once paid out.
Two practical notes: recordkeepers typically prepare the form, but the sponsor should confirm it's actually filed each year — it's a frequent gap discovered in audits; and keeping reported data in sync with actual payouts avoids ghost entries that generate confused participant inquiries years later.
