Self-Insured Medical Reimbursement Plan: Complete Guide

This comprehensive guide walks employers through the ins and outs of establishing a self‑insured Section 105 Medical Reimbursement Plan—also called a self‑insured HRA or SIMRP—where the employer reimburses employees directly for eligible medical expenses rather than paying insurance premiums.

Quick Links:

A self-insured medical reimbursement plan offers employers a tax-efficient way to cover employee healthcare expenses. Rather than purchasing traditional insurance, the employer reimburses medical costs directly. This approach can lower costs and provide more flexibility. Understanding how these plans work is essential for compliance and cost savings.

What Is a Self-Insured Medical Reimbursement Plan?

A self-insured medical reimbursement plan is an employer-funded arrangement. It reimburses employees for eligible out-of-pocket healthcare expenses. These plans are often used as alternatives to traditional group insurance. They are governed by Section 105 of the Internal Revenue Code.

Employers design the plan and define which expenses are reimbursable. Reimbursements are generally tax-free to employees. The employer claims a tax deduction for every approved reimbursement. A written plan document is required for compliance.

These plans are common among small businesses, especially those looking to control healthcare costs. Unlike insurance premiums, reimbursements are paid only when expenses occur. This creates potential savings and better cash flow management.

How the Plan Works

The employer sets up a formal plan outlining eligible expenses and reimbursement rules. Employees pay for healthcare services out-of-pocket. They then submit receipts and documentation to the employer for reimbursement. Once approved, the employer pays the reimbursement directly.

There are no third-party insurance premiums involved. The employer assumes the financial risk for employee medical expenses. However, employers can set annual limits to manage exposure. The plan may reimburse medical, dental, and vision expenses.

The plan must follow IRS and Department of Labor (DOL) rules. Substantiation of expenses is mandatory. Without proper documentation, the reimbursements may be taxable. Proper setup and recordkeeping are essential.

Eligible Expenses Under the Plan

The IRS defines eligible expenses under Section 213(d) of the tax code. These include doctor visits, surgeries, and prescription medications. Dental and vision care are also reimbursable. Mental health services and physical therapy may qualify too.

Premiums for individual insurance, Medicare, and long-term care can be included. Over-the-counter medications require a prescription to qualify. Expenses for dependents can also be reimbursed. This includes spouses and children under age 27.

Some expenses are not eligible. These include cosmetic procedures, non-prescribed vitamins, and general wellness items. Gym memberships and elective surgeries are typically excluded. Employers should clearly list allowable expenses in the plan document.

Advantages of a Self-Insured Reimbursement Plan

One of the main advantages is cost control. Employers only pay for actual expenses incurred. There are no fixed monthly premiums. This can lead to significant annual savings.

Reimbursements are tax-free to employees and deductible for the business. This creates a double tax benefit. Employees receive more value without increasing taxable income. Employers lower their tax liability while offering meaningful benefits.

Flexibility is another key advantage. Employers design the plan to suit their workforce and budget. Coverage limits and eligible expenses can be customized. This makes the plan adaptable to changing needs.

Who Can Use These Plans?

Any business can establish a self-insured medical reimbursement plan. C-corporations, S-corporations, partnerships, and sole proprietors are all eligible. However, the benefits vary by business structure. Tax treatment differs depending on ownership status.

C-corporation owners can fully participate in the plan. Reimbursements are tax-free to them. The corporation deducts the payments as fringe benefits. This structure works well for one-person businesses.

Sole proprietors and partnerships face limitations. Owners cannot receive tax-free reimbursements directly. But they can hire their spouse as a legitimate employee. The plan can then reimburse the spouse for family medical costs.

Compliance and Documentation Requirements

A formal, written plan document is required. It must describe who is eligible, what expenses are covered, and any reimbursement limits. The plan must be adopted before reimbursements begin. Retroactive reimbursements are not allowed.

All reimbursed expenses must be substantiated. This means employees must submit receipts or detailed invoices. Payments must match documented expenses exactly. Records should be kept for at least seven years.

The plan may be subject to ERISA rules. If only one employee is covered, some ERISA requirements may not apply. However, if additional employees are added, full compliance is necessary. Employers should consult a benefits advisor or tax professional.

Common Mistakes to Avoid

A common mistake is failing to use a written plan document. Without one, reimbursements may be taxable and non-deductible. Always create a compliant plan before issuing reimbursements. Do not rely on informal arrangements.

Another mistake is reimbursing ineligible individuals. For example, sole proprietors reimbursing themselves is not allowed. The IRS may disallow deductions and assess penalties. Ensure all recipients meet IRS employee criteria.

Failure to document expenses is also risky. Reimbursements must be supported by receipts or proof of payment. Do not issue payments based on estimates or verbal confirmation. This can lead to audits and tax issues.

Conclusion

A self-insured medical reimbursement plan provides a flexible, cost-effective alternative to traditional group insurance. With proper setup, it offers significant tax advantages and healthcare savings. However, compliance is critical. A written plan document, proper documentation, and understanding IRS rules are essential for success. For small business owners and corporations, this plan can be a smart way to support employee health while managing costs.
