A Section 105 medical reimbursement plan is one of the most powerful yet underused tax-saving strategies for small business owners and sole proprietors. It allows you to turn personal medical expenses into fully deductible business expenses while providing tax-free benefits to your spouse. This approach works especially well for family businesses where the spouse works as a bona fide employee. When structured correctly, this plan can reimburse all family medical expenses —such as health insurance, dental care, and vision costs—completely tax-free.

What Is a Section 105 Medical Reimbursement Plan?
A Section 105 plan is a type of Health Reimbursement Arrangement (HRA) that lets a business reimburse employees for medical expenses tax-free. When you employ your spouse in your business, you can set up a one-person HRA, making your spouse the employee and yourself the dependent. This allows your business to deduct 100% of the family’s medical expenses—including insurance premiums, co-pays, and prescriptions—on Schedule C. For example, if you’re a self-employed web designer in Virginia Beach and your spouse handles bookkeeping, you can reimburse her for the family’s $12,000 annual medical costs and deduct the entire amount as a business expense.
Key Requirements for a Spousal 105 Plan
To keep your plan compliant and effective, several key requirements must be met.
1. Bona Fide Employment: Your spouse must perform legitimate, documentable work for your business, such as administrative duties, recordkeeping, or marketing.
2. Written Plan and Employment Agreement: You need a formal, written plan describing the benefits and a signed employment agreement outlining your spouse’s duties.
3. Reasonable Compensation: The total pay, including medical reimbursements, must match the fair market value of your spouse’s work.
4. Proper Documentation: Maintain time sheets, receipts, and detailed reimbursement records. The IRS requires proof of hours worked and tasks completed.
5. One-Employee Rule: This strategy works best when your spouse is your only eligible employee. Adding others could trigger nondiscrimination rules under IRS Section 105(h).
| Requirement | Description | Example |
|---|---|---|
| Employment | Spouse performs real business duties | Bookkeeping, admin work |
| Documentation | Written plan and time records | Weekly logs and receipts |
| Reasonable Pay | Fair market value compensation | $30/hour + reimbursements |
| Proof of Expenses | Receipts and EOBs | Health insurance, dental bills |
Tax Benefits for Small Business Owners
The main advantage of a Section 105 plan is turning personal medical expenses into business deductions. These reimbursements are tax-free to your spouse and fully deductible for your business. This reduces both income and self-employment taxes. For instance, if your family spends $15,000 on medical costs annually and you’re in the 25% income tax bracket, this plan could save around $5,800 in combined federal and self-employment taxes. Additionally, reimbursements can cover health, dental, and vision insurance, long-term care premiums, and even over-the-counter items like prescription glasses or first aid supplies.
Do You Need to Pay Your Spouse a W-2 Wage?
The IRS allows the Section 105 plan to serve as the sole compensation for your employee-spouse. You don’t need to issue a W-2 wage if the medical reimbursements represent reasonable pay. The Speltz case (TC Summary Opinion 2006-25) confirmed this rule, where reimbursements were accepted as the only form of compensation. The IRS’s Industry Specialized Program (ISP) guidelines also state that reimbursements qualify as deductible if the spouse is a bona fide employee. However, small employers (under 250 W-2 filings) are exempt from reporting the plan’s value on Form W-2.
Documentation: The Key to Compliance
Strong documentation is critical. The Francis case (T.C. Memo 2007-33) shows that failing to maintain time sheets can invalidate your deductions. To prevent this, maintain:
-
Weekly time logs listing hours worked and tasks performed.
-
Receipts and proof of payments for all medical expenses.
-
Reimbursement records showing monthly payments to your spouse.
Avoid overly formal employment contracts; they often cause more problems than they solve. Instead, focus on time sheets and reimbursement logs to prove that your spouse is a real employee performing meaningful work.
How the Reimbursement Process Works
Once your spouse is hired, follow these simple steps:
-
Have your spouse pay all family medical bills from a personal checking account.
-
Each month, your spouse submits receipts and proof of payment.
-
Reimburse your spouse from your business checking account.
-
Record these payments as business expenses on Schedule C.
This system creates a paper trail and makes the plan look like a legitimate business benefit. For example, if your spouse pays $800 in health premiums and $400 in dental costs each month, you reimburse $1,200 and deduct it entirely as a business expense.
Eligibility by Business Type
The Section 105 plan applies differently depending on your business structure.
-
Sole Proprietors, Single-Member LLCs, and Partnerships: The plan is set up in the spouse’s name, with the owner covered as a dependent.
-
C Corporations: The owner can directly benefit as an employee, so hiring a spouse isn’t required.
-
S Corporations: Owners holding over 2% equity face restrictions. Their benefits may be taxable as income but remain exempt from FICA taxes.
| Business Type | Who Qualifies | Deduction Benefit | Notes |
|---|---|---|---|
| Sole Proprietor | Spouse as employee | 100% of family health costs | Most common setup |
| C Corporation | Owner-employee | 100% deductible | Spouse not required |
| S Corporation | >2% owners limited | Partial deduction | FICA exemption |
Common Mistakes to Avoid
Avoid these common pitfalls when setting up your Section 105 plan:
-
No written plan or employment documentation.
-
Missing time sheets or unclear work records.
-
Reimbursing expenses from personal accounts.
-
Paying unreasonable compensation or skipping reimbursements.
Each of these can lead to IRS disqualification, causing you to lose valuable deductions. Always treat your spouse like any other employee and maintain proper business records.
Example: Tax Savings in Action
Imagine a self-employed consultant in Fairfax, Virginia, who spends $18,000 yearly on family medical costs. By hiring her spouse as an administrative assistant and setting up a Section 105 plan, she deducts all medical expenses as business costs. At a 37% combined federal and self-employment tax rate, she saves $6,660 annually. Without this plan, she would likely receive no deduction at all due to IRS medical deduction limits.
Section 105 Plan vs. Traditional Deduction
| Feature | Section 105 Plan | Itemized Deduction |
|---|---|---|
| Deductibility | 100% of medical costs | After 7.5% of AGI threshold |
| Self-Employment Tax Savings | Yes | No |
| Required Documentation | Written plan, receipts | Basic receipts |
| Coverage | Family-wide | Limited |
