401(h) Plans for Small Business Owners: When Do They Make Sense?

For many small business owners, the idea of offering robust retiree health benefits while also enjoying significant tax advantages is appealing. However, a 401(h) plan isn't a one-size-fits-all solution.

These plans tend to make the most sense for profitable, stable businesses with predictable cash flow and an existing qualified defined benefit (DB) or cash balance plan. Businesses with episodic profits or small, transient workforces generally find the administrative burden and funding requirements too complex to justify the benefits.

Owners who prioritize tax deductions and long-term financial planning for their own retirement and key employees, and who are committed to maintaining a qualified retirement plan, are the most likely candidates to successfully implement and leverage a 401(h) sub-account. But they can work for many business owners.

Before delving into the specifics of a 401(h) plan design, business owners should engage in a thorough self-assessment. These foundational questions help clarify whether a 401(h) truly aligns with their business's financial capacity and long-term objectives. It's often beneficial to discuss these points with your financial advisor or benefits consultant early in the process.

Most owners benefit from sitting with these before any specific 401(h) conversation:

The allure of tax advantages can sometimes lead to misunderstandings about how 401(h) plans actually work. It's crucial to approach these plans with a clear understanding of their structure and limitations. A 401(h) is sometimes pitched as an open-ended tax shelter. It is not. It is a benefit structure with strict rules and ongoing obligations, and it works inside a qualified retirement plan that also has rules and obligations.

Owners should be wary of any advice that oversimplifies the complexity or exaggerates the flexibility of a 401(h) sub-account. Accurate information helps set realistic expectations regarding contributions, distributions, and the plan's overall operational requirements.

A 401(h) plan is not a standalone retirement plan. Instead, it operates as a separate medical benefit account within a qualified pension or annuity plan, most commonly a defined benefit or cash balance plan. This integration is key to its structure and compliance.

Contributions made to the 401(h) sub-account are generally tax-deductible for the employer, and earnings grow tax-free. When eligible retirees receive distributions for medical benefits, these benefits are typically tax-free to the recipient. This dual tax advantage — deduction at contribution, tax-free growth, and tax-free distributions — makes the 401(h) particularly attractive for funding post-retirement healthcare expenses.

The IRS imposes specific rules on 401(h) plans to ensure they are primarily used for retiree medical benefits and not as a circumventing tax shelter. A critical regulation is that contributions to the 401(h) account cannot exceed 25% of the total aggregate contributions made to the entire defined benefit or cash balance plan (excluding amounts necessary to fund past service liability). This limit helps maintain the primary purpose of the main pension plan.

Compliance also involves strict adherence to ERISA requirements, anti-discrimination rules, and regular actuarial valuations to ensure adequate funding. These complexities underscore the need for expert guidance in both the design and ongoing administration of a 401(h) plan.

Designing and maintaining a 401(h) plan is a sophisticated undertaking that requires a collaborative effort from multiple specialized professionals. An honest plan-design conversation with the plan's actuary, ERISA counsel, and your CPA — together — is the right starting point. A clear written design narrative beats slide-deck enthusiasm every time.

Each advisor brings a unique and essential perspective: the actuary ensures adequate funding and compliance with IRS limits, ERISA counsel navigates the legal complexities and fiduciary responsibilities, and your CPA integrates the plan into your overall tax strategy. This team approach helps to mitigate risks and optimize the plan's benefits for the business owner and eligible employees.
