The self-employed health insurance deduction, explained

Buying your own health insurance is expensive, but the tax code softens the blow with a deduction built specifically for the self-employed. It is generous, it does not require itemizing, and a surprising number of gig workers who qualify never claim it — usually because they do not know it exists or they trip over one eligibility rule.

What the deduction is

The self-employed health insurance deduction lets you deduct the premiums you pay for medical, dental, and qualifying long-term care coverage for yourself, your spouse, and your dependents. It is an above-the-line deduction, meaning it reduces your adjusted gross income directly, and you get it whether or not you itemize. For a gig worker paying several hundred dollars a month for a marketplace plan, that can be thousands of dollars off taxable income.

The eligibility rules

• You must have net profit from self-employment; the deduction is limited to that profit.
• You cannot be eligible for a subsidized health plan through your own employer or your spouse’s employer for any month you want to deduct.
• The policy can be in your name or the business’s name.

What counts and what does not

• Counts: medical and dental premiums, marketplace plan premiums (net of any advance premium tax credit you received), and age-limited amounts of long-term care premiums.
• Does not count for any month you (or your spouse) were eligible for a subsidized employer plan — even if you declined it.
• Does not include out-of-pocket medical costs; those follow separate rules (and an HSA if you have a high-deductible plan).

The bottom line: if you buy your own coverage and have self-employment profit, this deduction is one of the best available — it lowers your taxable income dollar for dollar on premiums without requiring you to itemize. Watch the employer-eligibility rule that trips up hybrid workers, remember it does not reduce self-employment tax, and because it interacts with marketplace subsidies in a circular way, let good tax software or a CPA handle the calculation.
