What Is Form 8955-SSA? Filing, Deadlines, and Penalties

Form 8955-SSA is the IRS registration statement that retirement plan administrators use to report separated participants who still have a vested benefit sitting in the plan. The IRS passes the data to the Social Security Administration, which later notifies those people about the benefit when they file for Social Security or Medicare. Most private-sector defined benefit and defined contribution plans have to file it; government plans, non-electing church plans, and owner-only plans do not.

Who Has To File

The plan administrator of any retirement plan subject to the vesting rules of Section 203 of ERISA must file Form 8955-SSA for each plan year in which a participant separates from service and keeps a right to a deferred vested benefit.¹ That sweeps in most 401(k) plans, traditional pensions, profit-sharing plans, and other qualified plans in the Form 5500 series.

A deferred vested benefit means the participant has earned a non-forfeitable benefit but isn’t yet receiving payments. If the departing employee rolled over the full balance or took a complete distribution, there’s nothing left to report for that person.

Plans That Don’t Have To File

Government plans, non-electing church plans, and plans covering only owners and their spouses (including solo 401(k) plans and partnership plans covering only partners and spouses) are outside ERISA’s vesting standards and are not required to file.² Administrators of these plans may file voluntarily, but there’s no penalty for skipping it.

When Form 8955-SSA Is Due

The form is due by the last day of the seventh month after the plan year ends.³ For a calendar-year plan, that’s July 31. It shares the Form 5500 due date, but the two are filed separately. Do not attach Form 8955-SSA to a Form 5500 or send it through the Department of Labor’s filing system.²

Filing Form 5558 before the original deadline extends the due date to the 15th day of the third month after the normal due date, which pushes a calendar-year plan to October 15.⁴ The extension is automatic if the Form 5558 arrives on time and the requested date stays within that limit.

What the Form Reports

The filing collects two kinds of information.

Plan Identifiers

At the plan level, the administrator reports the plan’s legal name, the sponsor’s name and address, the Employer Identification Number, and the three-digit plan number.²

Participant Entries

For each separated participant with a deferred vested benefit, the form asks for the full name and Social Security number, along with the nature, amount, and form of the benefit.¹ For a defined contribution plan, the amount is the account balance at plan year-end. For a defined benefit plan, it’s the benefit payable at normal retirement age.

Each participant needs a status code:²

Code A for a newly separated participant reported for the first time.
Code B for a previously reported participant whose information is being corrected.
Code C for a participant whose benefits were transferred from another employer’s plan and previously reported under that plan.
Code D for a previously reported participant who has since been paid out or is no longer entitled to a deferred vested benefit.

Code D is easy to overlook. Once a participant takes a full distribution or otherwise loses eligibility, you report them one more time under Code D to clear them from SSA’s records. Skipping that step leaves stale data in the system and can lead to future notices going to the wrong person.

How To Submit It

Filers required to submit at least 10 returns of any type to the IRS during the calendar year must file Form 8955-SSA electronically.⁵ That threshold catches most plan sponsors and third-party administrators. Electronic filing runs through the IRS FIRE (Filing Information Returns Electronically) system, usually via approved third-party payroll or benefits software.

If you qualify for an exception or receive a hardship waiver, paper forms go to the IRS Service Center in Ogden, Utah.² Either way, keep the filing confirmation. If the IRS later says the form never arrived, that receipt is your evidence.

One more submission point: Form 8955-SSA is not open to public inspection, unlike the Form 5500.² Because it contains Social Security numbers and benefit amounts, the IRS treats it as confidential tax information, which is another reason the two forms are never filed together.

Statements to Separated Participants

Filing with the IRS isn’t the end of the job. The administrator also has to furnish an individual statement to each separated participant listed on the form, and the deadline for delivering those statements is the same as the form’s filing deadline.¹ The statement tells the participant what was reported about their benefit and must include a notice of any benefits that would be forfeited if the participant dies before a certain date. When filing the form, the administrator has to give the IRS evidence that the statements went out.

Penalties

The penalty amounts here are higher than many plan administrators expect, particularly after the SECURE Act increases that took effect in 2020. Three separate penalties can apply.

Missing or Incomplete Registration Statement

Under IRC Section 6652(d)(1), failing to file Form 8955-SSA on time, or filing it without all required participants, costs $10 per unreported participant per day the failure continues. The maximum for any single plan year is $50,000.⁶ A plan with 20 unreported participants accrues $200 a day and hits the cap in 250 days; a plan with hundreds of participants reaches it much faster.

Missed Change-of-Status Notification

A separate penalty under IRC Section 6652(d)(2) applies when the administrator fails to notify the IRS of changes such as a new plan name, a change in the administrator’s name or address, a plan termination, or a merger. It runs at $10 per day, capped at $10,000.⁶

Willful Failure To Deliver a Participant Statement

An administrator who willfully fails to deliver a required individual statement to a separated participant faces a $50 penalty per participant.⁷ The “willful” qualifier draws a line between an honest clerical mistake and disregarding the requirement.

Reasonable Cause Relief

Both the registration penalty and the change-of-status penalty can be waived if the administrator shows the failure was due to reasonable cause.⁶ The statute doesn’t define the term, but reasonable cause generally means the administrator exercised ordinary business care and still couldn’t meet the deadline: a TPA system failure, destruction of records in a disaster, or reliance on incorrect professional advice. The IRS decides case by case. If a penalty notice arrives (usually Notice CP283C), respond in writing with documentation explaining what happened and why it was beyond your control.

Final Filing When a Plan Terminates

When a plan files its final Form 5500, the matching Form 8955-SSA has to report all remaining participants with deferred vested benefits and use Code D to clear anyone previously listed who has since been paid out.² It’s a common thing to miss during a plan wind-down, and the per-participant daily penalties make it an expensive one to miss.
