Self-Employed Health Insurance Deduction California

Self-Employed Health Insurance Deduction

Self-employed individuals in California can deduct 100% of health insurance premiums paid for themselves, their spouse, and their dependents as an above-the-line deduction — meaning it reduces your Adjusted Gross Income (AGI) before you even itemize. This deduction is available whether you take the standard deduction or itemize.

Who Qualifies for the Self-Employed Health Insurance Deduction

You qualify if you are self-employed (sole proprietor, single-member LLC, partner in a partnership, or S Corp shareholder-employee) and you paid health insurance premiums out of pocket. You do not qualify if you were eligible to participate in an employer-sponsored health plan through your own employer or your spouse's employer at any time during the year — even if you chose not to enroll.

What Premiums Count

Qualifying premiums include: medical insurance, dental insurance, vision insurance, and long-term care insurance (subject to age-based limits). Medicare premiums (Parts B, C, and D) paid by self-employed individuals over 65 also qualify. The premiums must be established under your business — either in your name or in the name of your business entity.

California-Specific Rules

California conforms to the federal self-employed health insurance deduction. California also has Covered California (the state health insurance marketplace), which offers subsidized plans for self-employed individuals. If you receive a premium tax credit through Covered California, you can only deduct the net premium you actually paid — not the subsidized portion.

Health Insurance for S Corp Owners

S Corp shareholders who own more than 2% of the company cannot receive health insurance as a tax-free employee benefit. Instead, the S Corp must include the health insurance premiums in the shareholder-employee's W-2 wages (Box 1), and the shareholder-employee then takes the self-employed health insurance deduction on their personal return. This is a specific compliance requirement that many S Corp owners miss.
