Introduction
Business owners in the United States often ask whether they can sponsor more than one retirement plan for employees. A common misconception is that companies can only sponsor one type of retirement plan. In reality, the IRS allows businesses to maintain multiple retirement plans, but strict rules apply regarding contribution limits, nondiscrimination testing, and plan coordination. Understanding these rules helps employers design effective retirement benefits while avoiding costly compliance errors.
1. Can a Company Have More Than One Retirement Plan?
Yes. Employers can offer more than one retirement plan at the same time, such as:
- 401(k) plan plus a profit-sharing plan
- 401(k) plan plus a defined benefit pension plan
- SEP IRA alongside another qualified plan (with restrictions)
However, the IRS requires coordination of contributions and benefits across all plans sponsored by the same employer or controlled group.
2. Contribution Limits Across Multiple Plans
The most important rule is that IRS contribution limits apply collectively across all plans, not per plan.
- Employee Elective Deferral Limit (2025): 22,500 across all 401(k), 403(b), SIMPLE, and similar plans.
- Catch-Up Contributions (age 50+): 7,500 additional.
- Overall Contribution Limit for Defined Contribution Plans (2025): 66,000 (or 73,500 with catch-up).
Example:
An employee contributes 20,000 to a 401(k). They cannot contribute another 20,000 to a different employer’s 401(k). Their total elective deferrals cannot exceed 22,500.
3. Defined Benefit and Defined Contribution Plan Combination
Companies may maintain both a defined benefit pension and a defined contribution plan (like a 401(k)). However:
- Combined benefits are subject to the IRC Section 415 limits.
- Defined benefit plans provide lifetime annuity promises, which require actuarial testing.
- Employers often use this strategy to maximize retirement savings for owners or key employees.
Example Calculation:
If an employer funds a defined benefit plan with an annual benefit value equivalent of 150,000 and also contributes 20,000 to a 401(k), the IRS requires compliance with Section 415 limits to ensure total benefits stay within legal thresholds.
4. Controlled Group Rules
If a business owner controls multiple companies, the IRS may treat them as a single employer under “controlled group” rules. This means:
- All employees across the companies may need to be considered for plan eligibility.
- Contribution and coverage testing apply across all entities.
5. Plan Testing and Compliance Requirements
When multiple plans exist, employers must perform additional compliance checks:
- Nondiscrimination Testing (NDT): Ensures benefits do not favor highly compensated employees (HCEs).
- Top-Heavy Testing: Ensures key employees do not receive disproportionate benefits.
- Annual Reporting (Form 5500): Each plan requires proper filing.
6. Common Combinations of Retirement Plans
Table: Examples of Multiple Retirement Plan Structures
| Plan Combination | Purpose | Compliance Notes |
|---|---|---|
| 401(k) + Profit-Sharing Plan | Boost savings potential | Combined limit: 66,000 total |
| 401(k) + Defined Benefit Pension Plan | Maximize tax deferrals for owners | Must meet Section 415 combined limits |
| SIMPLE IRA + SEP IRA | Generally not allowed in same year | IRS restricts overlap |
| 401(k) + Cash Balance Plan | Popular among professional firms | Requires actuarial certification |
7. Employer Considerations
Employers thinking of sponsoring multiple plans should:
- Consult a retirement plan advisor or ERISA attorney.
- Ensure contributions across plans comply with IRS limits.
- Consider the costs of additional testing, administration, and reporting.
- Evaluate whether employees will understand and use the benefits effectively.
Conclusion
The idea that companies can only sponsor one type of retirement plan is a myth. Employers may establish and maintain multiple plans, such as a 401(k) and a pension plan, but IRS rules require coordination of contributions, coverage, and nondiscrimination testing. By carefully structuring plan combinations, businesses can maximize tax benefits for owners while still offering competitive retirement options for employees. Proper planning and compliance are essential to avoid penalties and ensure retirement plans remain qualified.
