How to Read Your Form 5500 Like a Pro

Form 5500 is the annual report every U.S. retirement plan files with the Department of Labor. Once you know where to look, you can learn more about the health of a 401(k) plan in five minutes with a 5500 than in a two-hour meeting with its vendor. Here’s how to read one.

Start with the main form

The main Form 5500 (or Form 5500-SF for small plans) is the summary page. Three numbers matter most:

• Line 6a — Active participants. This tells you the plan’s size and whether an audit is required. 100+ participants on the first day of the plan year usually triggers the IQPA audit requirement under ERISA §103(a)(3).
• Line 6f — Total participants with account balances. Compare this to active participants. If only 60% of eligible employees have a balance, participation is low — often a design problem, not an employee problem.
• Line 7 — Plan type codes. These two-character codes describe what the plan does. “2E” means profit-sharing. “2J” means 401(k). “2R” means participant-directed accounts. Codes tell you whether you’re looking at a 401(k), money purchase, ESOP, defined benefit, or welfare plan.

That’s enough to know what you’re looking at. Now the schedules.

Schedule A — Insurance contracts

Schedule A is filed when a plan has insurance contracts — typically a group annuity or a stable value product. A single Schedule A won’t tell you much on its own, but pay attention to Part II, Commissions and Fees. This is where insurance brokers’ commissions show up. If you see a material commission being paid every year on what you thought was a fixed-income fund, you’ve learned something.

The tip: plans with old group annuity products often have surrender charges that silently prevent them from switching providers. Schedule A will often reveal whether you’re locked in.

Schedule C — Service providers (the real gold)

For plans that file Schedule C (generally large plans), this is the single most valuable page in the entire document. It lists every service provider paid $5,000 or more during the plan year, what they did, and — critically — how much they received in direct and indirect compensation.

• “Direct” compensation = fees paid straight from the plan (usually from participant accounts).
• “Indirect” compensation = revenue sharing, 12b-1 fees, sub-transfer-agent payments, float, and anything else the provider collected from third parties because of their relationship with your plan.

Read Schedule C carefully. The indirect compensation column is where the “free” 401(k) plan stops being free. A recordkeeper collecting $200,000 in indirect compensation on a $15M plan is collecting ~1.3% per year that never showed up on a single invoice.

What to look for:

• Any provider you don’t recognize (these are often sub-brokers)
• Indirect compensation larger than direct compensation (a sign of heavy revenue sharing)
• The same entity listed as multiple providers (common with bundled vendors)

Schedule H — Financial statements for large plans

Schedule H is where the money lives. It’s the plan’s balance sheet and income statement. For quickly scanning a plan’s health, these lines matter most:

• Line 1c — Total assets. The plan’s size.
• Line 2c — Contributions (employer, participant, other). Tells you whether the employer is actually funding the plan.
• Line 2e — Distributions and benefits paid. Useful if you’re wondering whether the plan is mostly in “accumulation” or is paying out retirees.
• Line 2i — Administrative expenses. Subtotal. Divide by line 1c to get your admin fee ratio. Above ~0.5% is worth a look. Above 1% is worth a conversation.
• Line 1c(13) — Employer securities. If this is more than about 15-20% of line 1c on a non-ESOP plan, there is employer-stock concentration worth reviewing.
• Line 3 — Accountant’s opinion. This is where the IQPA audit opinion is referenced. If it says “disclaimer” or “adverse,” stop and read the attached auditor’s report in full. If it says “unqualified” or “clean,” you’re in good shape on controls.

The tip: on Schedule H, always calculate total administrative expenses ÷ average plan assets. This single ratio is the quickest fee-health measure you can compute from a 5500.

Schedule R — Distributions

Schedule R (Retirement Plan Information) reports how many participants received distributions during the year, whether there were mandatory distributions, and whether the plan had amendments. Two things to watch:

• Unusually large lump-sum distributions — sometimes a sign of layoffs or an executive departure that would warrant plan amendments.
• Timing of amendments — plans that haven’t been amended in 4+ years may be behind on IRS/ERISA required language updates.

Schedule I — Small plan financial information

For plans under 100 participants that didn’t file the short Form 5500-SF, Schedule I is the small-plan version of Schedule H. It’s shorter, less detailed, and doesn’t require an audit. The key lines are expenses (ask: what percent of assets are you spending on admin?) and non-routine items like loans in default or corrective contributions.

Schedule MB / SB — Defined benefit actuarial information

Almost no modern 401(k) plan files these, but if you see them, you’re looking at a defined-benefit plan or a cash balance plan. Different animal entirely; the actuarial reports matter far more than the rest of the 5500 for these.

The five-minute read

If you’ve got five minutes and a single 5500 PDF, here’s the minimum-effective review:

1. Main form, line 6a and 6f. Plan size and participation rate.
2. Schedule H, line 2i ÷ line 1c. Admin fee ratio.
3. Schedule C, indirect compensation column. Hidden revenue sharing.
4. Schedule H, line 3 (accountant’s opinion). Clean audit?
5. Schedule H, line 1c(13). Employer stock concentration.

That’s the whole plan’s story in one page of notes. Everything else is detail.
