Health Insurance and the Self-Employed Deduction

Health insurance is one of the larger expenses self-employed people carry, and there is a deduction specifically designed for it. It is valuable and it comes with conditions that catch people out — particularly one involving a spouse's employer coverage.

What the deduction does

Self-employed individuals may be able to deduct premiums paid for medical, dental and qualifying long-term care insurance for themselves, their spouse and their dependents.

Importantly, this is taken as an adjustment to income rather than as an itemized deduction, which means it is generally available whether or not you itemize. That distinction makes it considerably more useful than the itemized medical expense deduction, which is subject to a threshold based on income.

The limitation people miss

The deduction is generally not available for any month in which you were eligible to participate in a subsidized health plan maintained by an employer of yours or your spouse.

Read that carefully: eligible to participate, not enrolled. If your spouse's employer offers subsidized coverage that you are eligible for, the deduction may be unavailable for those months even if you declined the coverage and bought your own policy instead.

This is the single most common way people get this wrong, and it comes up frequently in households where one spouse is employed and one is self-employed.

The income limitation

The deduction is generally limited to the net earnings from the business under which the plan is established. It cannot create or increase a loss.

Practically, a business with minimal or negative net income limits what can be deducted this way. Premiums beyond that limit may potentially be considered as itemized medical expenses instead, subject to the applicable threshold.

Whose business the plan is under

The plan generally must be established under the business. What satisfies that requirement differs depending on how the business is structured, and the mechanics for an S corporation shareholder-employee are different from those for a sole proprietor.

For S corporation owners in particular, there are specific steps involving how premiums are handled through payroll that must be followed for the treatment to work. Getting the mechanics wrong is a common issue, and it is worth confirming your setup rather than assuming.

What is included

Generally, medical insurance premiums, dental insurance premiums, and qualifying long-term care insurance premiums subject to limits that vary with age. Coverage for yourself, your spouse, your dependents, and in certain circumstances children under a specified age.

Not included: amounts paid with pre-tax dollars, since you cannot deduct what was never taxed in the first place.

Marketplace coverage and the premium tax credit

If you obtain coverage through the marketplace and receive a premium tax credit, the interaction between the credit and this deduction is genuinely complicated. There is a circular relationship — the deduction affects income, income affects the credit, and the credit affects the deductible premium amount.

This is one of the areas where working through it properly matters and where guessing produces wrong answers in either direction.

HSAs are a separate opportunity

If your coverage qualifies as a high deductible health plan, a health savings account offers its own advantages — contributions may be deductible, growth is not taxed, and qualified distributions are not taxed.

For self-employed people managing their own coverage, HSA eligibility is worth factoring into plan selection rather than treating it as an afterthought.

Where we fit

If you are self-employed and paying for your own coverage — particularly if your spouse has employer coverage available — this is worth working through specifically rather than assuming the deduction applies.
