How Small Businesses Can Deduct Health Insurance Premiums in Denver County

The Internal Revenue Service (IRS) allows qualifying small businesses to deduct health insurance premiums as an ordinary and necessary business expense. This deduction can apply to premiums paid for employees, their spouses, and dependents. The specific rules for the deduction depend on the business structure:

C Corporations: Premiums paid for employees (including owner-employees) are generally tax-deductible by the corporation and are not considered taxable income to the employees.
S Corporations: Premiums paid for a 2% shareholder-employee are deductible by the S corporation, but the premium amounts are included in the shareholder's gross income on their W-2. The shareholder can then deduct these premiums as a self-employed health insurance deduction on their personal income tax return (Form 1040, Schedule 1).
Partnerships and LLCs (taxed as partnerships): Partners can deduct premiums as a self-employed health insurance deduction, provided the partnership pays the premiums or provides funds for the partners to pay them, and the amounts are reported on their K-1.
Sole Proprietorships and Single-Member LLCs (taxed as sole proprietorships): Self-employed individuals can deduct health insurance premiums, including those for their spouse and dependents, as an adjustment to income on Form 1040, Schedule 1. This deduction is available if the individual is not eligible to participate in an employer-sponsored health plan through another job or a spouse's job.

Regardless of the business structure, the health insurance plan must be established by the business, and the premiums must be paid by the business to be eligible for the deduction.

The Small Business Health Care Tax Credit in Colorado

Beyond the deduction, some small businesses in Colorado may also qualify for the Small Business Health Care Tax Credit. This credit is designed to help small employers afford health insurance coverage for their employees. To be eligible, a business must:

Have fewer than 25 full-time equivalent (FTE) employees.
Pay average annual wages of less than $58,000 (for tax year 2023, adjusted annually).
Pay at least 50% of the cost of employee health insurance premiums.

The maximum credit is 50% of the premiums paid for small businesses and 35% for tax-exempt organizations. The credit is generally available for two consecutive tax years. Businesses must purchase coverage through the Small Business Health Options Program (SHOP) marketplace, which is part of Connect for Health Colorado, to be eligible for the tax credit. This credit can significantly reduce the out-of-pocket cost of providing health benefits, making it more feasible for smaller employers to offer competitive benefits.
