Fidelity Bond for a 401(k): Requirements & Costs

If you sponsor a 401(k) plan, you’ve probably heard the term “fidelity bond” (often called an ERISA bond)—usually right when you’re onboarding a new provider, filing your Form 5500, or preparing for an audit. It’s easy to confuse a fidelity bond with fiduciary liability insurance, but they’re not the same thing. A fidelity bond is a compliance requirement for most plans, and it’s designed to protect the plan (not the employer) if someone who handles plan funds commits fraud or dishonesty.

Below is a practical guide to what a fidelity bond for a 401(k) is, who needs it, how much coverage is required, and how to buy the right bond.

What is a fidelity bond for a 401(k)?

A 401(k) fidelity bond is an insurance-like bond required under ERISA that protects the plan against losses caused by acts of fraud or dishonesty by people who handle plan funds or other plan property.

In plain English: if someone with access to plan money steals it (or commits certain dishonest acts), the bond is meant to reimburse the plan up to the bond amount.

ERISA’s bonding requirement is administered by the U.S. Department of Labor (DOL). You can read the DOL’s overview of ERISA bonding requirements on DOL/EBSA’s ERISA fidelity bond fact sheet.

For a deeper walkthrough (including purchase tips and common mistakes), see our guide: What Is An ERISA Bond And How To Buy One? and our directory of ERISA bond providers.

Who needs an ERISA fidelity bond (and who must be covered)?

Most private-sector retirement plans—including many 401(k) plans—are required to be bonded. The rule generally applies to any person who “handles” plan funds, which can include:

• Owners, officers, and employees who can initiate or approve plan transactions

• HR or payroll staff who transmit employee deferrals or have access to plan accounts

• Plan administrators or internal committees with authority over plan assets

• Service providers who actually handle plan assets (in some arrangements)

“Handle” is broader than simply touching a check. It can include the ability to direct transfers, access plan accounts, or otherwise create a risk of loss.

Important: the fidelity bond protects the plan. It is not the same as fiduciary liability insurance, which is designed to protect the employer or fiduciaries against certain claims.

If you’re unsure who in your organization may be considered to “handle” plan funds, it’s often helpful to consult your plan advisor or ERISA counsel. If you’re evaluating help, see How To Hire A Retirement Plan Advisor and our directory of 401(k) financial advisors or ERISA attorneys.

How much fidelity bond coverage does a 401(k) need?

Under ERISA, the required bond amount is generally at least 10% of the amount of funds handled, subject to minimums and maximums set by law and regulation.

While the exact calculation can depend on facts and circumstances, many plan sponsors use a practical approach based on plan asset levels and who handles funds.

Key points to know:

• Minimum bond amount: generally $1,000

• Maximum bond amount: generally $500,000 per plan (higher in certain cases, such as plans holding employer securities)

• Coverage must be in place for every person who handles plan funds

The DOL provides additional detail on these limits and how the requirement works in its guidance, including the fact sheet linked above and related materials on EBSA’s website.

Practical tip: Many employers choose a bond amount that clearly satisfies the requirement (and avoids under-bonding) rather than trying to fine-tune the number to the dollar.

Fidelity bond vs. fiduciary liability insurance (common confusion)

These two are often mixed up during onboarding or renewal. Here’s the simplest way to separate them:

• ERISA fidelity bond: protects the plan from losses due to fraud/dishonesty by people who handle plan assets; often required by ERISA.

• Fiduciary liability insurance: can help protect the employer/plan fiduciaries from certain claims alleging breaches of fiduciary duty; generally optional (but commonly purchased).

Having fiduciary liability coverage does not replace the ERISA bonding requirement.

How to buy a fidelity bond for a 401(k) (step-by-step)

Purchasing an ERISA fidelity bond is usually straightforward, but mistakes can create compliance issues. Here’s a clean process most plan sponsors can follow:

1. Confirm the plan’s bonding requirement (most 401(k) plans are covered by ERISA, but verify your plan type and status).

2. Identify who handles plan funds (internal staff, committees, and possibly certain vendors depending on arrangement).

3. Calculate a compliant bond amount based on assets/funds handled and the ERISA minimum/maximum rules.

4. Purchase the bond from a qualified issuer and ensure the bond is written correctly (naming the plan and meeting ERISA requirements).

5. Keep documentation with your plan’s compliance records so it’s easy to produce during an audit or Form 5500 preparation.

How the fidelity bond shows up in Form 5500 and audits

Bonding is closely connected to annual reporting and, for larger plans, the audit requirement.

• Form 5500: Plans typically report fidelity bond information as part of the annual filing. If you need a refresher, see What is a Form 5500?.

• 401(k) audits: If your plan is subject to an annual audit, your auditor may ask for proof of the bond and review whether the amount appears compliant. Start here: What Is a 401(k) Audit and When Do I Need One? and What Is Needed for a 401(k) Audit and Where Do I Find It?.

If you are approaching the audit threshold or already require an audit, it helps to work with experienced specialists. You can explore our directory of 401(k) auditors (or browse all auditors if you sponsor multiple plan types). We also have directories for related plan audits, including 403(b) auditors, defined benefit plan auditors, ESOP auditors, and health & welfare auditors.

Common mistakes plan sponsors make with 401(k) fidelity bonds

Most bonding issues are avoidable. Watch for these frequent pitfalls:

• Buying the wrong product: confusing a fidelity bond with fiduciary liability insurance.

• Under-bonding: selecting a bond amount that doesn’t satisfy the 10% rule or applicable minimums.

• Incorrect named insured: the bond should be structured to protect the plan as required (details matter).

• Letting the bond lapse: gaps in coverage can create compliance exposure.

• Poor recordkeeping: not having the bond certificate available for Form 5500 prep or the annual audit.

Conclusion: treat the fidelity bond as core 401(k) compliance

A fidelity bond for your 401(k) is one of the simplest ERISA compliance items to get right—yet it’s often overlooked until a Form 5500 filing or audit brings it to the surface. If you confirm who handles plan funds, select a compliant bond amount, and keep clean documentation, you’ll reduce headaches and help protect the plan from real risk.
