Yes, 403(b) plans generally file Form 5500 every year, but only if they are covered by ERISA. Governmental 403(b) plans, most church 403(b) plans, and private-sector plans funded entirely by voluntary employee salary deferrals that meet a Department of Labor safe harbor are outside ERISA and have no Form 5500 obligation. Every other 403(b) plan, including any plan where the employer makes matching or nonelective contributions, must file.
Who Is Exempt From Filing
Three categories of 403(b) plans sit outside ERISA Title I and therefore outside the Form 5500 requirement:
- Plans sponsored by public schools and state or local government entities are excluded from ERISA Title I under section 4(b) of the statute.
- Plans maintained by churches or qualified church-controlled organizations are excluded unless the plan has affirmatively elected ERISA coverage.
- Private-sector 403(b) plans funded entirely through employee salary deferrals can escape ERISA coverage if they satisfy the DOL safe harbor at 29 CFR 2510.3-2(f).
If none of those fit your plan, it is ERISA-covered and it files.
The Safe Harbor for Voluntary Salary-Reduction Plans
The safe harbor treats certain 403(b) programs as though they were not established or maintained by an employer, which removes them from ERISA. All four of these conditions must be met:
- Participation is voluntary. Employees cannot be required or automatically enrolled.
- All rights under the annuity contract or custodial account belong exclusively to the employee or their beneficiary.
- The employer’s role is limited to forwarding salary-reduction contributions, holding a group annuity contract, and curating a reasonable selection of investment providers.
- The employer receives no direct or indirect consideration from the annuity contractor other than reasonable compensation for administrative services actually performed.
The third condition is where plans most often trip up. If the employer negotiates special fund lineups, picks a single provider with no alternatives, or exercises discretion beyond what the regulation permits, the safe harbor breaks. Once it breaks, the plan is ERISA-covered and the filing obligation applies retroactively. Administrators who are unsure whether their program still qualifies should err on the side of filing rather than face penalties for years of missed returns.1eCFR. 29 CFR 2510.3-2 Employee Pension Benefit Plan
Form 5500 or Form 5500-SF
ERISA-covered 403(b) plans pick between two versions of the form based on size. Plans with 100 or more participants file the full Form 5500. Plans with fewer than 100 participants can file Form 5500-SF, a streamlined version with less detailed financial reporting and fewer supplemental schedules.2Department of Labor. 2025 Instructions for Form 5500 Annual Return/Report of Employee Benefit Plan
Because 403(b) plans are defined contribution plans, the participant count that sets your filing status is based on participants with account balances at the beginning of the plan year, not everyone who is eligible. An employee who is eligible but has never contributed, and has no employer contribution sitting in an account, does not count toward your threshold.
The 80/120 rule gives plans near the line some cushion. If your plan had between 80 and 120 participants with account balances and you filed as a small plan the prior year, you can keep filing as a small plan even if you technically crossed 100. That prevents bouncing between forms because of routine hiring fluctuations.
Extra Test for Form 5500-SF
Filing the short form is not only about headcount. Throughout the entire plan year, 100% of the plan’s assets must qualify as eligible plan assets: assets with a readily determinable fair market value, not employer securities, and held by a regulated financial institution such as a bank, insurance company, registered broker-dealer, or mutual fund company. Participant loans meeting ERISA section 408(b)(1) also count.3U.S. Department of Labor, Employee Benefits Security Administration. 2025 Instructions for Form 5500-SF Short Form Annual Return/Report of Small Employee Benefit Plan
If a single asset falls outside those categories at any point during the year, the plan cannot use the short form. Plans holding real estate, private placements, or similar assets file the full Form 5500 with Schedule H.
What Goes Into the Filing
Form 5500 collects identifying information and a financial snapshot for the year. You need the plan sponsor’s name and Employer Identification Number, the plan’s original effective date, and the three-digit plan number assigned in prior filings. These identifiers must match your previous submissions exactly, because changing them between years creates processing problems.2Department of Labor. 2025 Instructions for Form 5500 Annual Return/Report of Employee Benefit Plan
Participant counts break into active contributors, retirees and separated employees receiving distributions, and separated employees who still have a balance but are not yet receiving benefits. On the financial side, administrators report beginning and end-of-year net assets, total employer and employee contributions, distributions, plan expenses, and service provider fees.
Supplemental Schedules
Depending on plan size and structure, one or more schedules attach:
- Schedule H covers detailed financial information for large plans and generally triggers the requirement to attach an audit report from an independent qualified public accountant.
- Schedule I is the financial schedule for small plans that file the full Form 5500 instead of Form 5500-SF. It does not require an independent audit.
- Schedule R reports retirement-plan-specific items such as distributions and funding details.
- Schedule A is required when the plan holds insurance contracts.
- Schedule C reports information about service providers who received compensation from the plan.
The independent audit attached to Schedule H is typically the most expensive piece of the annual compliance burden for large 403(b) plans.
Small Plan Audit Waiver
Small plans can avoid the independent audit if they meet asset-quality and bonding conditions. At least 95% of the plan’s assets as of the last day of the preceding plan year must be qualifying plan assets held by regulated financial institutions. Qualifying assets include mutual fund shares, bank custodial accounts, insurance company contracts, and securities held by a registered broker-dealer.4U.S. Department of Labor – Employee Benefits Security Administration. Frequently Asked Questions On The Small Pension Plan Audit Waiver Regulation
If the plan falls below 95%, the waiver is still available, but anyone handling the non-qualifying assets must be covered by a fidelity bond equal to at least 100% of those non-qualifying assets. The bond must name the plan as an insured, carry no deductible, and come from a surety company on the Treasury Department’s approved list. Assets held in a safe deposit box do not qualify even if the box is at a bank.
Deadline and Extensions
Form 5500 is due by the last day of the seventh month after the plan year closes. For a calendar-year plan, that is July 31.5Internal Revenue Service. Form 5500 Corner
Two extension routes exist:
- File Form 5558 with the IRS on or before the normal due date. It grants an automatic extension of up to two and a half months, pushing a calendar-year plan’s deadline to October 15. No approval letter is issued; a properly completed and timely-filed Form 5558 is automatically approved.6Internal Revenue Service. Form 5558 Application for Extension of Time To File Certain Employee Plan Returns
- If the plan year matches the employer’s tax year and the employer has already received an extension on its federal income tax return, the Form 5500 deadline automatically extends to the employer’s extended tax due date. Form 5558 is not needed, and you cannot stack the two extensions.
How to File Through EFAST2
All Form 5500 and Form 5500-SF filings must be submitted electronically through the EFAST2 system operated by the Department of Labor. Paper filings are not accepted.7U.S. Department of Labor. Form 5500 E-Filing Requirement
The person who signs the filing must register as a Filing Signer on EFAST2 and create a Login.gov account. Filing Signer credentials consist of a User ID and PIN that carry the same legal weight as a handwritten signature. Plan administrators, employers, and plan sponsors can sign directly, and a third-party service provider can sign with written authorization from the plan administrator. Every Filing Signer must read and accept the EFAST2 Signature Agreement during registration.
After uploading, check the submission status in the portal. EFAST2 shows whether the filing was accepted or rejected. A rejected filing does not satisfy the obligation, so errors need to be corrected and the return resubmitted before the deadline.
Penalties for Late or Missed Filings
Missing the Form 5500 deadline exposes the plan administrator to penalties from both the DOL and the IRS, and the two run simultaneously.
The DOL penalty under ERISA section 502(c)(2) is $2,739 per day for each day a required filing is late, with no statutory maximum. That figure is inflation-adjusted annually; the amount here reflects the 2025 adjustment.8Federal Register. Federal Civil Penalties Inflation Adjustment Act Annual Adjustments for 2025
The IRS imposes a separate penalty under IRC section 6652(e) of $250 per day, capped at $150,000 per late return. A return that is two full years late maxes out the IRS penalty entirely.9Office of the Law Revision Counsel. 26 U.S. Code 6652 – Failure To File Certain Information Returns, Registration Statements, Etc.
The plan administrator personally bears this liability, not the employer or the plan trust.
Fixing Delinquent Filings Through the DFVCP
If you have missed filings and have not yet been notified by the DOL of the failure, the Delinquent Filer Voluntary Compliance Program cuts penalties sharply. The program charges $10 per day of delinquency with these caps:
- Small plans: $750 per filing, capped at $1,500 per plan. Plans sponsored by 501(c)(3) organizations get a $750 per-plan cap.
- Large plans: $2,000 per filing, capped at $4,000 per plan.
The DOL provides an online penalty calculator at askebsa.dol.gov.10U.S. Department of Labor. DFVC Penalty Calculator
Completing the DFVCP also opens the door to IRS penalty relief. The IRS will generally waive its own late-filing penalties for administrators who satisfy the DFVCP requirements, provided they also file any missing Form 8955-SSA on paper with the IRS. The Form 8955-SSA must include “DFVC” in the Special Extension field and be mailed within 30 calendar days after completing the DFVCP filing.11Internal Revenue Service. IRS Penalty Relief for DOL DFVC Filers of Late Annual Reports
The DFVCP is not available to plan administrators who have already received a notice of intent to assess a penalty, plans that file Form 5500-EZ, or direct filing entities. If you know you have delinquent filings, the program rewards acting before the DOL contacts you.12U.S. Department of Labor – Employee Benefits Security Administration.
