How Self-Employed Individuals Can Deduct Health Insurance Premiums

If you're a self-employed individual in Boone County – meaning you own a business, are a partner in a partnership, or have net earnings from self-employment – you can often deduct the full amount of health insurance premiums you pay for yourself, your spouse, and your dependents. This is a particularly valuable deduction because it's taken "above-the-line," meaning it reduces your adjusted gross income (AGI) directly, rather than being an itemized deduction. To qualify for this deduction, you cannot be eligible to participate in an employer-sponsored health plan, such as one offered by your spouse's employer. This deduction covers premiums for medical, dental, and qualified long-term care insurance. For example, a self-employed individual with a median income of $84,571 in Boone County could significantly reduce their taxable income by deducting their health insurance costs.

Maximizing the Small Business Health Care Tax Credit

The Small Business Health Care Tax Credit is designed to help small employers afford health insurance for their employees. This credit can be worth up to 50% of the premiums you pay (up to 35% for tax-exempt organizations). To be eligible in Boone County, your business must meet specific criteria:

You must have fewer than 25 full-time equivalent (FTE) employees.
The average annual wages for your employees must be less than approximately $58,000 (this figure is adjusted annually by the IRS).
You must pay at least 50% of the premium cost for each employee covered by the health insurance plan.
You must purchase coverage through a Small Business Health Options Program (SHOP) marketplace or directly from a carrier if the plan is a "qualified health plan."

This credit is available for two consecutive tax years, providing substantial relief for small businesses like those found in Boone County, which has a population of 53,230 and an uninsured rate of 5.6% per U.S. Census Bureau ACS 2024 5-year estimates.

Understanding Tax Deductions for Group Health Plans

For small businesses in Boone County that offer a traditional group health plan to their employees, the premiums paid by the employer are generally 100% tax-deductible as a business expense. Furthermore, these contributions are not considered taxable income to the employees. This makes offering group health insurance a highly tax-efficient strategy for both the business and its workforce. When considering a group plan, you'll find various options available from carriers in Illinois. These typically include Health Maintenance Organizations (HMOs), Exclusive Provider Organizations (EPOs), and Preferred Provider Organizations (PPOs), with PPO plans being available on-exchange in Illinois. The ability to deduct these costs can make providing health benefits much more affordable, helping businesses attract and retain talent.
