19.4 Form 8955-SSA: Reporting Deferred Vested Participants & Related Registration Filings
Key Takeaways
- Form 8955-SSA reports participants who separated from service with a deferred vested benefit, so the Social Security Administration can notify them of the benefit when they claim Social Security.
- A participant is reported for the plan year following the plan year of separation, unless the benefit is paid out or the participant returns to service before the filing deadline, in which case reporting may be deferred or omitted.
- Form 8955-SSA is filed with the IRS — not through EFAST2 — on the same deadline as the Form 5500: the last day of the seventh month after the plan year end, extendable 2½ months by Form 5558.
- The penalty for failure to file is $10 per participant per day up to $50,000 per plan year under IRC §6652(d)(1), and a separate $10 per day up to $10,000 applies to a failure to furnish the individual statement to the participant.
The Filing Everyone Forgets
Form 5500 gets the attention. Form 8955-SSA — Annual Registration Statement Identifying Separated Participants With Deferred Vested Benefits — is the return that quietly generates penalty notices, because it is filed on a different system, to a different agency's ultimate benefit, and is easy to skip in a year with few terminations.
Purpose
When a participant leaves an employer with a vested benefit still in the plan, years may pass before they retire — and people forget. The plan reports them on Form 8955-SSA; the IRS transmits the data to the Social Security Administration; and when that individual later files for Social Security benefits, SSA sends them a Form SSA-L99-C1 potential private pension benefit notice telling them a plan may owe them money.
It is, in substance, a lost-participant prevention system. That framing matters because SECURE 2.0 §303 directed the DOL to build the Retirement Savings Lost and Found database, which draws on this same reporting stream.
Who Must Be Reported
A participant is reported if all of the following are true:
- They separated from service covered by the plan;
- They have a deferred vested benefit — a vested accrued benefit still held in the plan; and
- They have not previously been reported on a Form 8955-SSA for that benefit.
The Timing Rule
The general rule under IRC §6057(a): report the participant on the Form 8955-SSA for the plan year following the plan year in which the separation occurred.
| Event | Report on Form 8955-SSA for plan year |
|---|---|
| Separated in 2026, benefit still in the plan | 2027 |
| Separated in 2026, paid out in full during 2026 | Not reported at all |
| Separated in 2026, paid out during 2027 before the filing deadline | May be omitted at the administrator's election |
| Separated in 2026, rehired in 2027 before the filing deadline | May be omitted |
| Reported for 2027, benefit paid in 2029 | Optionally reported with Code D to delete the earlier entry |
The one-year lag exists precisely so that plans do not report participants who are about to be cashed out. In a plan with a $7,000 mandatory cash-out provision, most terminated participants are distributed within months and are never reported.
Who Is Not Reported
- Participants who received a full distribution of their vested benefit before the filing deadline;
- Participants who are fully non-vested at separation (a 0% vested participant with a deemed cashout has no deferred vested benefit);
- Participants already reported for the same benefit in a prior year;
- Participants who returned to service before the filing deadline.
Entry Codes
| Code | Meaning |
|---|---|
| A | A participant being reported for the first time |
| B | A participant previously reported whose information is being revised |
| C | A participant previously reported under another plan number, whose benefit has been transferred |
| D | A participant previously reported who is no longer entitled to the deferred vested benefit — used to delete a prior entry |
Code D is optional but valuable: without it, SSA continues telling retirees they may have a benefit in a plan that paid them years ago, generating fruitless inquiries to the administrator.
Filing Mechanics
| Element | Rule |
|---|---|
| Filed with | The IRS — not through EFAST2 |
| Method | Electronically through the IRS FIRE system, or on paper |
| Deadline | Last day of the 7th month after the plan year end — July 31 for a calendar-year plan |
| Extension | 2½ months via Form 5558, to October 15 for a calendar-year plan |
| Automatic extension | If the employer's federal income tax return is extended, and the plan year and tax year coincide, an automatic extension applies |
| Participant statement | The administrator must furnish each reported participant an individual statement describing the deferred vested benefit, no later than the date the Form 8955-SSA is filed |
The EFAST2 point is the one most commonly tested. Form 5500 goes to EFAST2; Form 8955-SSA goes to the IRS. Filing the 5500 does not satisfy the 8955-SSA obligation, and the two returns are penalized separately.
Penalties
| Failure | Penalty |
|---|---|
| Failure to file Form 8955-SSA (IRC §6652(d)(1)) | $10 per participant per day, capped at $50,000 per plan year |
| Failure to furnish the individual participant statement (IRC §6652(d)(2)) | $10 per day, capped at $10,000 per plan year |
| Reasonable cause | Penalties may be waived where the failure is due to reasonable cause and not willful neglect |
Worked example. Bellwether Freight terminated 40 participants during 2026, all with vested balances above the $7,000 cash-out threshold and none distributed. The plan should report all 40 on the 2027 Form 8955-SSA, due July 31, 2028 (or October 15, 2028 with Form 5558). If the plan never files, the penalty accrues at 40 × $10 = $400 per day, reaching the $50,000 annual cap in 125 days. If 12 of those participants take distributions in early 2028 before the filing deadline, the administrator may omit them and report the remaining 28.

Common ASPPA QKA Exam Traps
- Trap 1 — Filing Form 8955-SSA through EFAST2. It goes to the IRS.
- Trap 2 — Reporting in the year of separation. The general rule is the following plan year.
- Trap 3 — Reporting a participant who was cashed out before the deadline. They may be omitted.
- Trap 4 — Forgetting the individual participant statement. It carries its own separate penalty.
- Trap 5 — Mixing up the codes. A is a new entry; D deletes a prior one.
- Trap 6 — Reporting a 0% vested terminated participant. No deferred vested benefit exists.
