The right health insurance strategy for your small business depends primarily on one question: do you have employees? Your situation as the owner is different from your obligation (or opportunity) to cover staff.
| Business size | Coverage for you (owner) | Coverage for employees |
|---|---|---|
| Solo / no employees | ACA marketplace + SE deduction Medicaid if income qualifies |
N/A |
| 1–24 employees | Marketplace or group plan (as owner-employee if S-corp) | Group plan optional; QSEHRA up to $6,350/$12,800 reimbursement |
| 25–49 employees | Usually group plan as owner-employee | Group plan optional; SHOP tax credit may apply; ICHRA alternative |
| 50+ full-time equivalent employees | Group plan as employer | ACA mandate: must offer affordable coverage to FT employees or face penalties |
Health Insurance for Small Business Owners
Small business owners face health insurance decisions on two tracks simultaneously: their own personal coverage, and whether and how to provide coverage for employees. These are governed by different rules, different tax treatments, and different federal requirements depending on business size.
Coverage for the Owner: The Self-Employment Health Insurance Deduction
Sole proprietors, partners in partnerships, and S-corp shareholders who own more than 2% of the company can deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents as an above-the-line deduction on their federal tax return. This deduction:
- Does not require itemizing
- Appears on Schedule 1 (Form 1040), not on your business Schedule C
- Reduces your adjusted gross income (MAGI), which can affect marketplace subsidy eligibility
- Is limited to your net self-employment income for the year
- Is not available in any month when you or your spouse were eligible for employer group coverage through another job
For an S-corp owner-employee, the health insurance premiums are run through the business payroll, included in Box 1 of your W-2 (but not in Box 3 or 5), and then deducted on Schedule 1. This requires coordination with your payroll provider but effectively makes the premiums exempt from Social Security and Medicare taxes — a meaningful savings at high income levels.
ACA Marketplace Plans for Owners Without Employees
If you have no employees, the ACA marketplace is typically your most accessible option. Marketplace plan subsidies are available if your net income falls within the eligible range, and the self-employment deduction can help reduce your MAGI closer to the subsidy eligibility threshold. A sole proprietor with $70,000 in gross profit and $12,000 in legitimate business deductions has a net of $58,000 — which may qualify for some premium tax credit depending on location and household size.
Coverage for Employees: Your Options as a Small Employer
Group health insurance (SHOP)
Small businesses with 1–50 employees can offer ACA-compliant group health insurance through the Small Business Health Options Program (SHOP). SHOP plans can be purchased through licensed brokers and meet ACA requirements. Small employers with fewer than 25 full-time equivalent employees and average wages below $56,000/year may qualify for the Small Business Health Care Tax Credit — worth up to 50% of the employer’s premium contribution for up to two consecutive years.
QSEHRA (Qualified Small Employer HRA)
For employers with fewer than 50 full-time employees who do not offer a group health plan, a QSEHRA allows you to reimburse employees tax-free for individual health insurance premiums and out-of-pocket medical expenses. 2026 limits: $6,350/year for self-only, $12,800/year for family coverage. The business deducts the reimbursements as a business expense; employees receive the reimbursement tax-free. Employees must have their own ACA-compliant coverage to receive QSEHRA funds.
ICHRA (Individual Coverage HRA)
An ICHRA is similar to a QSEHRA but has no employer size limit and no maximum reimbursement amount. The employer sets their own monthly reimbursement budget by employee class (full-time, part-time, seasonal, etc.) and reimburses employees for individual plan premiums. ICHRA is more flexible than QSEHRA but more complex to administer. Employees receiving ICHRA reimbursements that cover the full cost of an ACA-compliant plan are not eligible for marketplace premium tax credits.
The 50 Full-Time Equivalent Employee Threshold
Once your business has 50 or more full-time equivalent employees (FTEs), you become an Applicable Large Employer (ALE) subject to the ACA employer mandate. You must offer affordable minimum essential coverage to all full-time employees (those working 30+ hours/week) or face potential Employer Shared Responsibility Payments. This threshold is measured on a prior-year average — a business that had 55 FTEs in 2025 is subject to the mandate in 2026. A licensed broker can help you structure coverage that meets mandate requirements and minimizes your cost. Call (713) 575-9904 for a free consultation.
