What Is IRS Form 5310-A?

IRS Form 5310-A, officially titled “Notice of Plan Merger or Consolidation, Spinoff, or Transfer of Plan Assets or Liabilities; Notice of Qualified Separate Lines of Business,” serves as a notification tool under Internal Revenue Code sections 6058(b) and 414(r). Employers use it to inform the IRS about major changes to pension, profit-sharing, or other deferred compensation plans.

The form’s primary purposes include:

  • Reporting a plan merger or consolidation, where two or more plans combine into one.
  • Notifying about a plan spinoff, which splits a single plan into multiple plans.
  • Detailing a transfer of plan assets or liabilities, involving the movement of portions from one plan (transferor) to another (transferee).
  • Electing, modifying, or revoking treatment as qualified separate lines of business (QSLOBs), allowing separate testing for compliance with nondiscrimination rules under sections 410(b), 401(a)(26), and 129(d)(8).

Unlike determination letter applications (e.g., Form 5310 for plan terminations), filing Form 5310-A does not result in an IRS determination letter. It’s purely a notice to ensure transparency and compliance with qualification rules, particularly section 414(l) for benefit protections.

Form 5310-A is a one-page document revised in November 2010, but instructions are updated periodically. It’s structured into three parts:

  • Part I: General information for all filers, including the reason for filing and sponsor details.
  • Part II: Specifics for mergers, consolidations, spinoffs, or transfers.
  • Part III: Details for QSLOB notices.

This form is crucial for maintaining tax-qualified status, as improper handling of these transactions could lead to disqualification or excise taxes.

Who Must File IRS Form 5310-A?

Filing responsibility falls on the plan sponsor or administrator. Key scenarios include:

  • Sponsors of single-employer pension, profit-sharing, or deferred compensation plans (excluding multiemployer plans covered by Pension Benefit Guaranty Corporation (PBGC) insurance).
  • For mergers, spinoffs, or transfers: File separately for each plan with its own Employer Identification Number (EIN) and plan number. For spinoffs, file only for the original (pre-spinoff) plan.
  • For QSLOBs: The employer files one notice covering all plans, as QSLOB treatment applies employer-wide.

Exceptions where filing is not required:

  • Direct rollovers under section 401(a)(31).
  • Certain small-scale transactions meeting safe harbors in Regulations section 1.414(l)-1, such as mergers where transferred liabilities are under 3% of the larger plan’s assets, or spinoffs where assets equal participant account balances in defined contribution plans.

If your plan is terminating entirely, you may need Form 5310 instead, along with Form 5310-A if a merger or transfer is involved prior to termination.

When and Where to File IRS Form 5310-A?

Timing is critical to avoid penalties:

  • For mergers, consolidations, spinoffs, or transfers: File at least 30 days before the transaction date.
  • For QSLOB notices: File by the later of October 15 of the year following the testing year or the 15th day of the 10th month after the earliest plan year beginning in the testing year. The testing year is typically the calendar year.

Submit the form to:

  • Internal Revenue Service, TE/GE Stop 31A Team 105, P.O. Box 12192, Covington, KY 41012-0192.
  • For express or private delivery: 7940 Kentucky Drive, Florence, KY 41042.

Use certified mail or designated private delivery services for proof of timely filing. Electronic filing is not available for this form, but check IRS updates for changes.
