IRS Form 15091 – Benefit Assurance – In the complex world of employee benefits and retirement planning, ensuring compliance with IRS regulations is crucial for employers and plan administrators. One lesser-known but important document in this arena is IRS Form 15091, also known as the Benefit Assurance form. This form plays a key role in the termination process of certain retirement plans, helping to verify that all participant benefits have been properly distributed. Whether you’re a plan sponsor dealing with a terminating defined benefit pension plan or a tax professional advising on plan closures, understanding Form 15091 can help avoid costly penalties and ensure a smooth wind-down.
In this comprehensive guide, we’ll break down what IRS Form 15091 is, who needs it, how to complete it, and key considerations for submission. We’ll draw from official IRS sources to provide accurate, up-to-date information as of 2026.
What Is IRS Form 15091?
IRS Form 15091, titled “Benefit Assurance,” is a certification document used primarily in the context of terminating qualified retirement plans, such as defined benefit pension plans. It serves as a formal assurance to the IRS that all liabilities to plan participants have been fully satisfied through specific methods, such as purchasing guaranteed annuity contracts or making lump sum distributions.
The form was last revised in January 2019 and is available for download directly from the IRS website. It’s not a standalone tax return but rather a supporting document often required during the IRS review of plan terminations, especially when there’s a reversion of excess assets to the employer. Reversions occur when a plan has more assets than needed to cover participant benefits, and without proper handling, they can trigger a 50% excise tax under IRC Section 4980.
Key elements of the form include:
- Basic Plan Information: Employer Identification Number (EIN), plan name, plan number, and contact details.
- Termination Details: Date of plan termination.
- Distribution Breakdown: Dates and amounts for excess assets received, annuity contracts purchased, and lump sum payments made.
- Certification Statement: A signed affirmation that all participant liabilities are settled.
This form helps the IRS confirm that the plan termination complies with ERISA (Employee Retirement Income Security Act) requirements, particularly under Section 4044, which governs asset allocation in terminations.
Who Needs to File IRS Form 15091?
Not every retirement plan termination requires Form 15091. It’s specifically relevant for:
- Terminating Defined Benefit Plans: Plans where excess assets are reverting to the employer or being transferred to a qualified replacement plan.
- Plans Seeking Favorable Determination Letters: During IRS review, if a plan has reversions, the IRS may generate a “Benefit Assurance Form Alert” and require this certification as part of the enclosures in the determination letter process.
- Employers Avoiding Excise Taxes: To qualify for excise tax relief under IRC 4980, employers must meet conditions like transferring at least 25% of excess assets to a replacement plan where at least 95% of active participants join. Form 15091 supports this by certifying benefit distributions.
Plan sponsors, administrators, or authorized representatives typically file this form. It’s not for individual taxpayers but for entities managing qualified plans. If your plan involves life insurance contracts or prohibited transactions during termination, additional scrutiny may apply, making this form even more critical.
If you’re unsure whether your situation requires Form 15091, consult the IRS Internal Revenue Manual (IRM) sections on plan terminations or seek guidance from a tax advisor familiar with employee plans.
Step-by-Step Guide: How to Fill Out IRS Form 15091
Completing Form 15091 is straightforward but requires accurate records from the plan termination process. Here’s a breakdown:
- Header Information:
- Enter the current date.
- Provide the Employer Identification Number (EIN) and Document Locator Number (DLN), if applicable.
- Include the plan sponsor’s address, person to contact, and contact telephone number.
- Plan Details:
- List the plan name and three-digit plan number (e.g., 001 for the first plan).
- Termination and Distribution Data:
- Note the date of plan termination.
- Detail the dates and amounts for:
- Excess assets received by the employer.
- Guaranteed annuity contracts purchased (include total amounts).
- Lump sum distributions paid to participants.
- Certification:
- Sign the form, include your title (e.g., Plan Administrator), and date it.
- The certification reads: “I certify that the above plan’s liabilities to all plan participants have been satisfied by the purchase of guaranteed annuity contracts or the payment of lump sum distributions.”
Ensure all information aligns with PBGC (Pension Benefit Guaranty Corporation) filings and ERISA allocations. Errors could delay IRS approval or trigger audits.
Where and How to Submit IRS Form 15091?
Once completed, mail the form to the address specified on the document:

Key Considerations and Common Pitfalls
- Excise Tax Implications: If excess assets revert without meeting IRC 4980(d) conditions, a 50% tax applies. Using Form 15091 correctly can help demonstrate compliance.
- Coordination with Other Forms: This form often accompanies Form 5310 (Application for Determination Upon Termination) or PBGC filings.
- Updates and Revisions: As of 2026, the January 2019 version remains in use, with no major changes noted in IRS publications.
- Professional Advice: Plan terminations involve legal and tax complexities. Engage an ERISA attorney or CPA to avoid issues like prohibited transactions.
