When Is Form 5500 Due?

For most employee benefit plans, Form 5500 is due by the last day of the seventh month after the plan year ends, so a calendar-year plan generally files by July 31 of the following year. A plan with a different year-end has a different deadline, calculated from its own plan year rather than the employer’s tax year or benefits renewal date. In some cases, a plan administrator can extend the deadline by filing Form 5558 on time. The filing requirement and the form a plan must use depend on factors such as plan type, participant count, and funding arrangement. Confirm the applicable deadline and filing requirements in the Form 5500 instructions for the relevant filing year, since missing a required filing can create penalty exposure.

The regular deadline is generally the last day of the seventh month after the plan year ends. For a calendar-year plan, that means the filing is due July 31 of the following year.

Plans with a fiscal year that does not end on December 31 use the same general rule. For example, a plan year ending June 30 would generally have a deadline at the end of the following January. The deadline follows the plan year, which may differ from the employer’s tax year, payroll calendar, or benefits renewal date. An organization sponsoring multiple plans should check the year-end for each plan separately.

Which Plans Must File Form 5500?

Form 5500 is an annual report used by many employer-sponsored retirement and welfare benefit plans. It gives federal agencies information about a plan’s operation, financial condition, and compliance with ERISA. Depending on the plan, the filing may involve the U.S. Department of Labor, the Internal Revenue Service, and, for certain pension plans, the Pension Benefit Guaranty Corporation.

Not every plan files the same form or has the same filing obligation. Larger plans typically file the standard Form 5500 with financial schedules. Smaller plans, generally those with fewer than 100 participants at the start of the plan year, may qualify for a simplified filing. A plan covering only a business owner and, in some cases, a spouse, with no other employees, may qualify to file Form 5500-EZ instead of the standard form. Some welfare plans with very few participants and fully insured, unfunded benefits may qualify for an exemption under specific small-plan exceptions.

These classifications depend on the plan’s type, participant count, and funding arrangement. Do not assume that last year’s filing category still applies. Review the Department of Labor instructions each year to determine which form, if any, applies. A plan that is exempt from filing does not have the same Form 5500 deadline as a plan required to submit a return.

Can You Extend the Filing Deadline?

A plan administrator may generally receive an automatic extension of up to 2½ months by filing Form 5558 on or before the original Form 5500 due date. The extension gives additional time to complete the filing, but it does not change the original deadline for requesting the extension.

For a calendar-year plan with a regular deadline of July 31, 2026, a timely extension would generally move the deadline to October 15, 2026. Form 5558 must be submitted by July 31. Waiting until after the regular due date to request an extension can mean the automatic extension is unavailable.

An extension is most useful when the plan team has identified missing information and assigned responsibility for completing the filing. It provides more time to resolve outstanding work, not a reason to postpone preparation. The Form 5500 instructions also describe possible agency extensions in certain circumstances, including disasters or military service. These forms of relief are situation-specific.

How Is Form 5500 Filed?

Form 5500 filings are submitted electronically through the Department of Labor’s EFAST2 system. Plan teams should allow time to confirm system access and identify who will review, authorize, and submit the filing. A vendor or service provider may prepare a draft, but the plan sponsor or administrator should confirm who is responsible for submission and verify that it was accepted.

Common sources of delay include incomplete or inconsistent participant data, unfinished financial information or schedules, late information from vendors or advisers, uncertainty about which plan documents apply, difficulty obtaining an electronic signature or authorization, and errors found during final review. Starting early gives the team time to address these issues before the deadline.

How Should You Prepare for the Deadline?

Form 5500 preparation is easier to manage as an annual process rather than a last-minute July task. A practical schedule can give the people responsible for the filing time to collect and review information.

Three to Four Months Before the Due Date

Confirm the plan year-end and identify the person responsible for filing. Review the prior year’s return and note plan changes, provider changes, mergers, terminations, or corrections that could affect the current filing. Request information from recordkeepers, insurers, third-party administrators, and other providers early enough to allow time for preparation and reconciliation.

Six to Eight Weeks Before the Due Date

Check the information received for completeness and consistency. Compare participant counts, plan assets, employer contributions, and other key entries with prior-year information and internal records. Investigate unusual figures while there is still time to resolve questions. If the team cannot complete the filing by the regular deadline, plan to submit Form 5558 on time.

Two to Three Weeks Before the Due Date

Complete the final review and confirm that the people responsible for signing or authorizing the filing are available. Check electronic filing access and confirm who will submit the return. Do not assume that a draft prepared by a vendor has been filed.

After Filing

Keep the filing confirmation, submitted return, supporting records, and related correspondence together. A complete record helps with future reporting, plan audits, participant requests, and internal compliance reviews.

What If the Deadline Has Passed?

If the regular deadline has passed and no timely extension was filed, first establish the plan’s actual filing status. Check whether the return was submitted, whether an extension was filed, and whether the filing was accepted. A missing copy in the employer’s records does not necessarily mean the filing was missed, but it should be investigated promptly.

Late filings can carry meaningful penalty exposure, and programs may be available to help reduce penalties for plans that come forward voluntarily. The available response depends on the plan type, filing history, and reason for the missed deadline. The applicable Form 5500 instructions explain the filing requirements and relevant procedures.

How Can You Keep the Next Filing on Schedule?

Add Form 5500 preparation to the annual benefits calendar. Assign a clear filing owner, document what information each provider must supply, and request that information well before the deadline. Set an internal review date ahead of the regular due date so there is time to finish the filing or submit Form 5558 before the original deadline.
