Section 105 Medical Reimbursement Plans: A 2026 Guide for Small Business Owners
A Section 105 plan is a written, employer-funded arrangement that lets a business reimburse employees for medical expenses and, in some setups, health insurance premiums. The reimbursements are deductible for the business and, when the plan follows the rules, are not taxable income to the employee. The name comes from Section 105 of the Internal Revenue Code, which excludes these employer reimbursements from an employee's income.
Most owners who search for a "105 plan" are really asking one of three questions: can my business pay for health coverage tax-free, can I include myself, and which version of the plan fits my company. This page answers all three.
How a Section 105 plan works
- 1. The business adopts a written plan document. It names who is eligible, what is covered, and how claims are reimbursed. A plan that exists only as a habit is not a plan.
- 2. Only the employer funds it. Reimbursements cannot come out of employee paychecks.
- 3. Employees submit proof of expenses. Receipts or statements are substantiated before money is paid.
- 4. The business reimburses qualified expenses: medical care as defined in IRC Section 213(d), which can include premiums for some coverage, deductibles, copays, prescriptions, dental and vision costs.
- 5. The business deducts the reimbursements, and the employee generally owes no income or payroll tax on them.
Who can participate, including owners
Whether an owner can benefit depends on how the business is organized:
| Business type | Can the owner participate directly? | Common path |
|---|---|---|
| C corporation | Yes, owner-employees are employees | Owner can be covered by the plan |
| Sole proprietor | No | Hire your spouse as a genuine W-2 employee; the plan covers the employee's family, which includes you |
| Partnership / multi-member LLC | No | Same spouse-employee path, if the spouse is not a partner |
| S corporation (more than 2% shareholder) | No | Premiums can be paid by the S corp and reported as wages, then deducted on the owner's return |
Self-employed people are not treated as employees under Section 105(g), which is why a sole proprietor can't reimburse themselves directly.
The spouse-employee plan
The spouse-employee version is the one most small family businesses use. The owner hires their spouse to do real work, at reasonable pay, documented like any other employee. The business adopts a Section 105 plan covering that one employee and their family. Because the spouse's family includes the owner and children, the plan can reimburse the whole household's qualified medical costs.
What makes or breaks it:
- the spouse does real, documented work for the business;
- the plan is in writing before expenses are reimbursed;
- the spouse is the only eligible employee; adding a second employee changes the rules (see below);
- every reimbursement has a receipt.
The rule that catches owners: reimbursing individual premiums for staff
Once a business has two or more eligible employees, a plan that pays or reimburses employees' individual health insurance premiums is treated as a group health plan. Under IRS Notice 2013-54, an arrangement like that generally fails federal group-plan rules unless it is set up as one of the approved designs, and the penalty can be $100 per day for each affected employee.
That is why multi-employee businesses usually use a QSEHRA or ICHRA instead of a homemade premium-reimbursement plan.
Section 105 plan vs. QSEHRA vs. ICHRA (2026)
| Spouse-only Section 105 plan | QSEHRA | ICHRA | |
|---|---|---|---|
| Who it fits | Family business, spouse is the only employee | Employers under 50 full-time employees with no group plan | Employers of any size |
| 2026 dollar limit | No set IRS cap | $6,450 self-only / $13,100 family | No IRS cap |
| Coverage employees need | None specific | Qualifying individual coverage | Qualifying individual coverage |
| Owner participation | Through the spouse-employee | Not for sole proprietors, partners or more-than-2% S-corp owners | Same as QSEHRA |
QSEHRA limits for 2026 come from IRS Revenue Procedure 2025-32.
Common mistakes
- reimbursing without a written plan;
- paying a spouse who doesn't do real work;
- reimbursing non-medical expenses or paying cash allowances with no receipts;
- adding employees and keeping a premium-reimbursement setup that no longer qualifies;
- assuming every insurance plan can be reimbursed through every kind of HRA; the coverage requirements differ.
