What Is Form 5500 and Does Your Business Have to File It?

What Form 5500 is for

It reports a benefit plan's finances, investments, participants and operations so regulators can monitor compliance with federal law.

If your business sponsors a 401(k), profit-sharing plan, pension or certain health and welfare plans, the plan has an annual reporting duty under ERISA and the Internal Revenue Code. The Form 5500 series is how that duty is met. It also gives participants a way to see how the plan is run, since the filings are public.

Offering a plan is one of the ways small businesses compete for talent, as covered in employee benefits and how employer 401(k) contributions work. Filing is the administrative price of doing it properly.

Which version applies

The main versions are the full Form 5500, the shorter Form 5500-SF for eligible small plans, and Form 5500-EZ for certain one-participant plans.

• Form 5500. The standard return, with schedules, for most plans, especially larger ones.
• Form 5500-SF. A short form for eligible small plans, typically those with fewer than 100 participants that meet specific conditions.
• Form 5500-EZ. For plans covering only the owner and spouse, or partners and spouses, that must file. Some of these plans are exempt from filing below an asset threshold.

Eligibility turns on participant counts, plan assets and plan type, and the thresholds can change. Check the current instructions on the Department of Labor or IRS site, or ask your plan administrator or third-party administrator (TPA).

What information you will need

Expect to provide plan and sponsor identifiers, participant counts, asset and income totals, and financial statements or audit data where required.

Collect these items before filing season:

• Employer identification number and plan number
• Plan year dates and plan type
• Number of participants at the start and end of the year
• Asset and liability totals from the custodian's statements
• Employer and employee contribution amounts
• Service provider and fee information, where required
• An independent audit report, if the plan is large enough to require one

Contribution timing matters. Employee deferrals must be deposited into the plan promptly after withholding. Late deposits are a common problem for small businesses with tight cash flow. See how to do payroll for process tips.

Deadlines and extensions

The return is generally due on the last day of the seventh month after the plan year ends, with a possible extension using Form 5558.

For a calendar-year plan, that is typically July 31. An extension of up to two and a half months is available by filing Form 5558 before the original due date. Filing is done electronically through the Department of Labor's EFAST2 system, usually via your TPA or recordkeeper.

Put the date on your compliance calendar the same way you track payroll tax deadlines and quarterly taxes. Verify dates each year, because weekends and rule changes can shift them.

Penalties for late or missing filings

Penalties can be steep and accrue daily for late filers. Programs exist for voluntary correction, so act quickly if you missed a deadline.

Both the Department of Labor and the IRS can assess penalties, and amounts are adjusted over time, so we do not quote figures here. Ask an ERISA attorney or your TPA for current numbers.

If you discover a missed filing:

1. Do not ignore it. Penalties grow with time.
2. Ask your plan advisor about the Department of Labor's delinquent filer program and IRS correction programs.
3. Gather the missing years' data.
4. File and keep proof of submission.

Do you have to sponsor a plan at all?

No. Offering a retirement plan is voluntary for most small employers, and the filing burden is one reason owners compare plan types first.

Some states require employers without a plan to enroll employees in a state-run program. Check your state's rules. If you do choose to sponsor, simpler plans such as SIMPLE IRAs or SEP IRAs often carry lighter reporting than a 401(k), though each has its own contribution rules. Our piece on the solo 401(k) vs. SEP IRA covers options for owner-only businesses.

Costs include employer match, setup and annual administration fees. Add these to your budget alongside other benefit costs. Your accountant or a benefits adviser can model what is affordable.

Funding benefits and compliance costs

Employer contributions and plan fees are predictable monthly costs. Plan for them in your cash flow before you promise a match.

Illustrative example: a 4% match on $400,000 of covered payroll is $16,000 a year, about $1,333 a month, plus administration fees. If margins are thin, a missed deposit can create compliance problems. A cash-flow forecast helps; start with cash flow forecasting.
