C-corporations have unique advantages in providing medical benefits. A medical reimbursement plan, or Section 105 plan, lets the business reimburse employees—including owners—for medical expenses tax-free.
When properly structured, these plans offer substantial tax benefits to C-Corp owners. But there are a few compliance tips that you must keep in mind.
In this guide, we will discuss how these plans work and offer some planning strategies. Let’s jump in!
What Is a C-Corp Medical Reimbursement Plan?
A C Corp medical reimbursement plan is funded by the corporation and lets the company reimburse employees for eligible medical expenses in a tax-advantaged way. These reimbursements are tax-free to employees and fully deductible to the corporation, creating a double tax benefit.
Section 105 of the Internal Revenue Code governs the plan. It requires a written document stating rules, eligibility, and limits. Unlike group insurance, the plan reimburses actual expenses, not fixed premiums, offering flexibility and cost control.
A C Corp can offer this benefit to any employee, including owner-employees, making it appealing for closely held corporations. Proper documentation and IRS compliance are key.
Who Can Participate?
Having outlined what a C-Corp medical reimbursement plan is, let’s clarify who is eligible to benefit from such a plan.
All C-Corporation employees—including owners, family members, and non-owners—are eligible to participate. Unlike S Corps or sole proprietors, C Corp owners are treated as employees for tax purposes.
This enables owner-employees, as well as their spouses and dependents, to get tax-free reimbursements. Even a one-person C-Corp qualifies if the owner is the only employee.
There are no income limits or minimums, but avoid discrimination among employees to preserve favorable tax treatment. All full-time employees should have fair access.
Eligible Medical Expenses
A C-Corp medical reimbursement plan covers a wide range of expenses under IRS Section 213(d): doctor visits, dental, vision, prescriptions, hospital stays, and lab fees all qualify.
Health insurance premiums, including individual, family, and Medicare, are reimbursable. Long-term care insurance is also eligible with some restrictions. Over-the-counter drugs may qualify if prescribed.
Cosmetic procedures and general wellness items like gym memberships or vitamins are usually excluded. The plan document should clarify covered expenses to avoid confusion and ensure compliance.
How to Set Up a Plan
To set up a C-Corp medical reimbursement plan, draft a written plan document specifying eligibility, covered expenses, and reimbursement procedures. Include clear timing and process instructions.
Maintain proper records for each reimbursement. Employees must submit receipts for claims. Payments come from the corporate account and should not appear on W-2s.
Communicate the plan to employees so they know what’s covered and how to submit expenses. Use forms and tracking tools for simplicity and IRS compliance.
Benefits of a C-Corp Medical Reimbursement Plan
The most obvious benefit is tax savings—reimbursements are excluded from employee wages and the corporation deducts 100% as a business expense.
Flexibility is another advantage. Employers can design the plan to suit their needs without statutory reimbursement limits, making budgeting simple.
Offering health reimbursements shows commitment to employee wellness, improving satisfaction and retention. Small companies benefit without group insurance costs.

Common Mistakes to Avoid
A major mistake is failing to use a written plan document—without one, reimbursements may become taxable. Always have a legally valid document before issuing payments.
Improper documentation is another issue. Each reimbursement needs receipt proof. Vague or missing documentation risks plan disqualification; keep detailed records.
Not applying nondiscrimination rules is risky; offer the plan fairly to all employees. Favoring highly compensated employees risks loss of tax benefits.
Bottom Line
A C-Corp medical reimbursement plan is one of the most tax-efficient benefits for corporations, enabling tax-free reimbursements, full corporate deductions, and flexible plan design. Whether for a one-person or small team, proper planning and compliance can turn medical expenses into valuable deductions and satisfaction gains.
